• SortList duplicated key, but it shouldn't

  - by Luca

  I have a class which implements IList interface. I requires a "sorted view" of this list, but without modifying it (I cannot sort directly the IList class). These view shall be updated when the original list is modified, keeping items sorted. So, I've introduced a SortList creation method which create a SortList which has a comparer for the specific object contained in the original list. Here is the snippet of code: public class MyList<T> : ICollection, IList<T> { ... public SortedList CreateSortView(string property) { try { Lock(); SortListView sortView; if (mSortListViews.ContainsKey(property) == false) { // Create sorted view sortView = new SortListView(property, Count); mSortListViews.Add(property, sortView); foreach (T item in Items) sortView.Add(item); } else sortView = mSortListViews[property]; sortView.ReferenceCount++; return (sortView); } finally { Unlock(); } } public void DeleteSortView(string property) { try { Lock(); // Unreference sorted view mSortListViews[property].ReferenceCount--; // Remove sorted view if (mSortListViews[property].ReferenceCount == 0) mSortListViews.Remove(property); } finally { Unlock(); } } protected class SortListView : SortedList { /// <summary> /// /// </summary> /// <param name="property"></param> /// <param name="capacity"></param> public SortListView(string property, int capacity) : base(new GenericPropertyComparer(typeof(T).GetProperty(property, BindingFlags.Instance | BindingFlags.Public)), capacity) { } /// <summary> /// Reference count. /// </summary> public int ReferenceCount = 0; /// <summary> /// /// </summary> /// <param name="item"></param> public void Add(T item) { Add(item, item); } /// <summary> /// /// </summary> /// <param name="item"></param> public void Remove(T item) { // Base implementation base.Remove(item); } /// <summary> /// Compare object on a generic property. /// </summary> class GenericPropertyComparer : IComparer { #region Constructors /// <summary> /// Construct a GenericPropertyComparer specifying the property to compare. /// </summary> /// <param name="property"> /// A <see cref="PropertyInfo"/> which specify the property to be compared. /// </param> /// <remarks> /// The <paramref name="property"/> parameter imply that the compared objects have the specified property. The property /// must be readable, and its type must implement the IComparable interface. /// </remarks> public GenericPropertyComparer(PropertyInfo property) { if (property == null) throw new ArgumentException("property doesn't specify a valid property"); if (property.CanRead == false) throw new ArgumentException("property specify a write-only property"); if (property.PropertyType.GetInterface("IComparable") == null) throw new ArgumentException("property type doesn't IComparable"); mSortingProperty = property; } #endregion #region IComparer Implementation public int Compare(object x, object y) { IComparable propX = (IComparable)mSortingProperty.GetValue(x, null); IComparable propY = (IComparable)mSortingProperty.GetValue(y, null); return (propX.CompareTo(propY)); } /// <summary> /// Sorting property. /// </summary> private PropertyInfo mSortingProperty = null; #endregion } } /// <summary> /// Sorted views of this ReactList. /// </summary> private Dictionary<string, SortListView> mSortListViews = new Dictionary<string, SortListView>(); } Practically, class users request to create a SortListView specifying the name of property which determine the sorting, and using the reflection each SortListView defined a IComparer which keep sorted the items. Whenever an item is added or removed from the original list, every created SortListView will be updated with the same operation. This seems good at first chance, but it creates me problems since it give me the following exception when adding items to the SortList: System.ArgumentException: Item has already been added. Key in dictionary: 'PowerShell_ISE [C:\Windows\sysWOW64\WindowsPowerShell\v1.0\PowerShell_ISE.exe]' Key being added: 'PowerShell_ISE [C:\Windows\system32\WindowsPowerShell\v1.0\PowerShell_ISE.exe]' As you can see from the exception message, thrown by SortedListView.Add(object), the string representation of the key (the list item object) is different (note the path of the executable). Why SortList give me that exception? To solve this I tried to implement a GetHashCode implementation for the underlying object, but without success: public override int GetHashCode() { return ( base.GetHashCode() ^ mApplicationName.GetHashCode() ^ mApplicationPath.GetHashCode() ^ mCommandLine.GetHashCode() ^ mWorkingDirectory.GetHashCode() ); }

• Understanding the passing of data/life of a script in web development/CodeIgniter

  - by Pete Jodo

  I hope I worded the title accurately enough but I typically use Java and don't have much experience in Web Development/PHP/CodeIgniter. I have a difficult time understanding the life cycle of a script as I found out trying to implement a certain feature to a website I am developing (as a means of learning how to). I'll first describe the feature I tried implementing and then the problem I ran into that made me question my fundamental understanding of how scripts work since I'm used to typical OOP. Ok so here goes... I have a webpage that has 2 basic tasks a user can do, create and delete an entry. What I attempted to implement was a way to time a user how long it takes them to complete a certain task. The way I did this was have a homepage where there would be a list of tasks a user to choose from (in this case 2, create and delete). A user would click a task which would link to the 'true' homepage where the user then would be expected to complete the task. My script looks like this: <?php class Site extends CI_Controller { var $task1; var $tasks = array( "task1" => NULL, "date1" => 0, "date2" => 0, "diff" => 0); function __construct() { parent::__construct(); include 'timetask.php'; $this->task1 = new TimeTask("create"); } function index() { $this->tasks['task1'] = $this->task1->getTask(); $this->tasks['diff'] = $this->task1->getTimeDiff(); if($this->tasks['diff'] == NULL) { $this->tasks['diff'] = 0; } $this->load->view('usability_test', $this->tasks); } function origIndex() { $this->task1->setDate1(new DateTime()); $this->tasks['date1'] = $this->task1->getDate1()->getTimestamp(); $data = array(); if($q = $this->site_model->get_records()) { $data['records'] = $q; } $this->load->view('options_view', $data); } function create() { $this->task1->setDate2(new DateTime()); $this->tasks['date2'] = $this->task1->getDate2()->getTimestamp(); $data = array( 'author' => $this->input->post('author'), 'title' => $this->input->post('title'), 'contents' => $this->input->post('contents') ); $this->site_model->add_record($data); $this->index(); } I only included create to keep it short. Then I also have the TimeTask class, that actually another StackOverflow so kindly helped me with: <?php class TimeTask { private $task; /** * @var DateTime */ private $date1, $date2; function __construct($currTask) { $this->task = $currTask; } public function getTimeDiff() { $hasDiff = $this->date1 && $this->date2; if ($hasDiff) { return $this->date2->getTimestamp() - $this->date1->getTimestamp(); } else { return NULL; } } public function __toString() { return (string) $this->getTimeDiff(); } /** * @return \DateTime */ public function getDate1() { return $this->date1; } /** * @param \DateTime $date1 */ public function setDate1(DateTime $date1) { $this->date1 = $date1; } /** * @return \DateTime */ public function getDate2() { return $this->date2; } /** * @param \DateTime $date2 */ public function setDate2(DateTime $date2) { $this->date2 = $date2; } /** * @return get current task */ public function getTask() { return $this->task; } } ?> I don't think posting the views is necessary for the question but here is atleast how the links are made. ...and... id", $row-title); ? Now there's no error in the code but it doesn't do what I expect of it and the reason I assume why is because that each time a function of the script is called via a new page it is NOT the same instance of the script called previously so any previously created objects are no longer there. This confuses me and leaves me quite unsure of how to implement this gracefully. Some ways I would guess of how to do this is by passing the necessary data through the URL or have data saved in a database and retrieve it later to compare the times. What would be a recommended way to do, not just this, but anything that needs previously created data? Also, am I correct to think that a script is only 'alive' for one webpage at a time? Thanks!

• Throttling Cache Events

  - by dxfelcey

  The real-time eventing feature in Coherence is great for relaying state changes to other systems or to users. However, sometimes not all changes need to or can be sent to consumers. For instance; If rapid changes cannot be consumed or interpreted as fast as they are being sent. A user looking at changing Stock prices may only be able to interpret and react to 1 change per second. A client may be using low bandwidth connection, so rapidly sending events will only result in them being queued and delayed A large number of clients may need to be notified of state changes and sending 100 events p/s to 1000 clients cannot be supported with the available hardware, but 10 events p/s to 1000 clients can. Note this example assumes that many of the state changes are to the same value. One simple approach to throttling Coherence cache events is to use a cache store to capture changes to one cache (data cache) and insert those changes periodically in another cache (events cache). Consumers interested in state changes to entires in the first cache register an interest (event listener) against the second event cache. By using the cache store write-behind feature rapid updates to the same cache entry are coalesced so that updates are merged and written at the interval configured to the event cache. The time interval at which changes are written to the events cache can easily be configured using the write-behind delay time in the cache configuration, as shown below.   <caching-schemes>     <distributed-scheme>       <scheme-name>CustomDistributedCacheScheme</scheme-name>       <service-name>CustomDistributedCacheService</service-name>       <thread-count>1</thread-count>       <backing-map-scheme>         <read-write-backing-map-scheme>           <scheme-name>CustomRWBackingMapScheme</scheme-name>           <internal-cache-scheme>             <local-scheme />           </internal-cache-scheme>           <cachestore-scheme>             <class-scheme>               <scheme-name>CustomCacheStoreScheme</scheme-name>               <class-name>com.oracle.coherence.test.CustomCacheStore</class-name>               <init-params>                 <init-param>                   <param-type>java.lang.String</param-type>                   <param-value>{cache-name}</param-value>                 </init-param>                 <init-param>                   <param-type>java.lang.String</param-type>                   <!-- The name of the cache to write events to -->                   <param-value>cqc-test</param-value>                 </init-param>               </init-params>             </class-scheme>           </cachestore-scheme>           <write-delay>1s</write-delay>           <write-batch-factor>0</write-batch-factor>         </read-write-backing-map-scheme>       </backing-map-scheme>       <autostart>true</autostart>     </distributed-scheme>   </caching-schemes> The cache store implementation to perform this throttling is trivial and only involves overriding the basic cache store functions. public class CustomCacheStore implements CacheStore { private String publishingCacheName; private String sourceCacheName; public CustomCacheStore(String sourceCacheStore, String publishingCacheName) { this.publishingCacheName = publishingCacheName; this.sourceCacheName = sourceCacheName; } @Override public Object load(Object key) { return null; } @Override public Map loadAll(Collection keyCollection) { return null; } @Override public void erase(Object key) { if (sourceCacheName != publishingCacheName) { CacheFactory.getCache(publishingCacheName).remove(key); CacheFactory.log("Erasing entry: " + key, CacheFactory.LOG_DEBUG); } } @Override public void eraseAll(Collection keyCollection) { if (sourceCacheName != publishingCacheName) { for (Object key : keyCollection) { CacheFactory.getCache(publishingCacheName).remove(key); CacheFactory.log("Erasing collection entry: " + key, CacheFactory.LOG_DEBUG); } } } @Override public void store(Object key, Object value) { if (sourceCacheName != publishingCacheName) { CacheFactory.getCache(publishingCacheName).put(key, value); CacheFactory.log("Storing entry (key=value): " + key + "=" + value, CacheFactory.LOG_DEBUG); } } @Override public void storeAll(Map entryMap) { if (sourceCacheName != publishingCacheName) { CacheFactory.getCache(publishingCacheName).putAll(entryMap); CacheFactory.log("Storing entries: " + entryMap, CacheFactory.LOG_DEBUG); } } }  As you can see each cache store operation on the data cache results in a similar operation on event cache. This is a very simple pattern which has a lot of additional possibilities, but it also has a few drawbacks you should be aware of: This event throttling implementation will use additional memory as a duplicate copy of entries held in the data cache need to be held in the events cache too - 2 if the event cache has backups A data cache may already use a cache store, so a "multiplexing cache store pattern" must also be used to send changes to the existing and throttling cache store.  If you would like to try out this throttling example you can download it here. I hope its useful and let me know if you spot any further optimizations.

• NullReferenceException makes me want to shoot myself

  - by rockinthesixstring

  Ok, so once upon a time, my code worked. Since then I did some refactoring (basic stuff so I thought) but now I'm getting a null reference exception, and I can't bloody well figure out why. Here's where it starts. note, this is the logout method, but all of my ActivityLogs sections are throwing this error Function LogOut(ByVal go As String) As ActionResult ActivityLogService.AddActivity(AuthenticationHelper.RetrieveAuthUser.ID, _ IActivityLogService.LogType.UserLogout, _ HttpContext.Request.UserHostAddress) ActivityLogService.SubmitChanges() ''# more stuff happens after this End Function The service is pretty straight forward (notice the ERROR THROWN HERE) Public Sub AddActivity(ByVal userid As Integer, ByVal activity As Integer, ByVal ip As String) Implements IActivityLogService.AddActivity Dim _activity As ActivityLog = New ActivityLog With {.Activity = activity, .UserID = userid, .UserIP = ip.IPAddressToNumber, .ActivityDate = DateTime.UtcNow} ActivityLogRepository.Create(_activity) ''#ERROR THROWN HERE End Sub And the Interface that the Service uses looks like this Public Interface IActivityLogService Sub AddActivity(ByVal userid As Integer, ByVal activity As Integer, ByVal ip As String) Function GetUsersLastActivity(ByVal UserID As Integer) As ActivityLog Sub SubmitChanges() ''' <summary> ''' The type of activity done by the user ''' </summary> ''' <remarks>Each int refers to an activity.

• How to detect crashing tabed webbrowser and handle it?

  - by David Eaton

  I have a desktop application (forms) with a tab control, I assign a tab and a new custom webrowser control. I open up about 10 of these tabs. Each one visits about 100 - 500 different pages. The trouble is that if 1 webbrowser control has a problem it shuts down the entire program. I want to be able to close the offending webbrowser control and open a new one in it's place. Is there any event that I need to subscribe to catch a crashing or unresponsive webbrowser control ? I am using C# on windows 7 (Forms), .NET framework v4 =============================================================== UPDATE: 1 - The Tabbed WebBrowser Example Here is the code I have and How I use the webbrowser control in the most basic way. Create a new forms project and name it SimpleWeb Add a new class and name it myWeb.cs, here is the code to use. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows.Forms; using System.Security.Policy; namespace SimpleWeb { //inhert all of webbrowser class myWeb : WebBrowser { public myWeb() { //no javascript errors this.ScriptErrorsSuppressed = true; //Something we want set? AssignEvents(); } //keep near the top private void AssignEvents() { //assign WebBrowser events to our custom methods Navigated += myWeb_Navigated; DocumentCompleted += myWeb_DocumentCompleted; Navigating += myWeb_Navigating; NewWindow += myWeb_NewWindow; } #region Events //List of events:http://msdn.microsoft.com/en-us/library/system.windows.forms.webbrowser_events%28v=vs.100%29.aspx //Fired when a new windows opens private void myWeb_NewWindow(object sender, System.ComponentModel.CancelEventArgs e) { //cancel all popup windows e.Cancel = true; //beep to let you know canceled new window Console.Beep(9000, 200); } //Fired before page is navigated (not sure if its before or during?) private void myWeb_Navigating(object sender, System.Windows.Forms.WebBrowserNavigatingEventArgs args) { } //Fired after page is navigated (but not loaded) private void myWeb_Navigated(object sender, System.Windows.Forms.WebBrowserNavigatedEventArgs args) { } //Fired after page is loaded (Catch 22 - Iframes could be considered a page, can fire more than once. Ads are good examples) private void myWeb_DocumentCompleted(System.Object sender, System.Windows.Forms.WebBrowserDocumentCompletedEventArgs args) { } #endregion //Answer supplied by mo. (modified)? public void OpenUrl(string url) { try { //this.OpenUrl(url); this.Navigate(url); } catch (Exception ex) { MessageBox.Show("Your App Crashed! Because = " + ex.ToString()); //MyApplication.HandleException(ex); } } //Keep near the bottom private void RemoveEvents() { //Remove Events Navigated -= myWeb_Navigated; DocumentCompleted -= myWeb_DocumentCompleted; Navigating -= myWeb_Navigating; NewWindow -= myWeb_NewWindow; } } } On Form1 drag a standard tabControl and set the dock to fill, you can go into the tab collection and delete the pre-populated tabs if you like. Right Click on Form1 and Select "View Code" and replace it with this code. using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using mshtml; namespace SimpleWeb { public partial class Form1 : Form { public Form1() { InitializeComponent(); //Load Up 10 Tabs for (int i = 0; i <= 10; i++) { newTab("Test_" + i, "http://wwww.yahoo.com"); } } private void newTab(string Title, String Url) { //Create a new Tab TabPage newTab = new TabPage(); newTab.Name = Title; newTab.Text = Title; //create webbrowser Instance myWeb newWeb = new myWeb(); //Add webbrowser to new tab newTab.Controls.Add(newWeb); newWeb.Dock = DockStyle.Fill; //Add New Tab to Tab Pages tabControl1.TabPages.Add(newTab); newWeb.OpenUrl(Url); } } } Save and Run the project. Using the answer below by mo. , you can surf the first url with no problem, but what about all the urls the user clicks on? How do we check those? I prefer not to add events to every single html element on a page, there has to be a way to run the new urls thru the function OpenUrl before it navigates without having an endless loop. Thanks.

• Multiple (variant) arguments overloading in Java: What's the purpose?

  Browsing google's guava collect library code, I've found the following: // Casting to any type is safe because the list will never hold any elements. @SuppressWarnings("unchecked") public static <E> ImmutableList<E> of() { return (ImmutableList<E>) EmptyImmutableList.INSTANCE; } public static <E> ImmutableList<E> of(E element) { return new SingletonImmutableList<E>(element); } public static <E> ImmutableList<E> of(E e1, E e2) { return new RegularImmutableList<E>( ImmutableList.<E>nullCheckedList(e1, e2)); } public static <E> ImmutableList<E> of(E e1, E e2, E e3) { return new RegularImmutableList<E>( ImmutableList.<E>nullCheckedList(e1, e2, e3)); } public static <E> ImmutableList<E> of(E e1, E e2, E e3, E e4) { return new RegularImmutableList<E>( ImmutableList.<E>nullCheckedList(e1, e2, e3, e4)); } public static <E> ImmutableList<E> of(E e1, E e2, E e3, E e4, E e5) { return new RegularImmutableList<E>( ImmutableList.<E>nullCheckedList(e1, e2, e3, e4, e5)); } public static <E> ImmutableList<E> of(E e1, E e2, E e3, E e4, E e5, E e6) { return new RegularImmutableList<E>( ImmutableList.<E>nullCheckedList(e1, e2, e3, e4, e5, e6)); } public static <E> ImmutableList<E> of( E e1, E e2, E e3, E e4, E e5, E e6, E e7) { return new RegularImmutableList<E>( ImmutableList.<E>nullCheckedList(e1, e2, e3, e4, e5, e6, e7)); } public static <E> ImmutableList<E> of( E e1, E e2, E e3, E e4, E e5, E e6, E e7, E e8) { return new RegularImmutableList<E>( ImmutableList.<E>nullCheckedList(e1, e2, e3, e4, e5, e6, e7, e8)); } public static <E> ImmutableList<E> of( E e1, E e2, E e3, E e4, E e5, E e6, E e7, E e8, E e9) { return new RegularImmutableList<E>( ImmutableList.<E>nullCheckedList(e1, e2, e3, e4, e5, e6, e7, e8, e9)); } public static <E> ImmutableList<E> of( E e1, E e2, E e3, E e4, E e5, E e6, E e7, E e8, E e9, E e10) { return new RegularImmutableList<E>(ImmutableList.<E>nullCheckedList( e1, e2, e3, e4, e5, e6, e7, e8, e9, e10)); } public static <E> ImmutableList<E> of( E e1, E e2, E e3, E e4, E e5, E e6, E e7, E e8, E e9, E e10, E e11) { return new RegularImmutableList<E>(ImmutableList.<E>nullCheckedList( e1, e2, e3, e4, e5, e6, e7, e8, e9, e10, e11)); } public static <E> ImmutableList<E> of( E e1, E e2, E e3, E e4, E e5, E e6, E e7, E e8, E e9, E e10, E e11, E e12, E... others) { final int paramCount = 12; Object[] array = new Object[paramCount + others.length]; arrayCopy(array, 0, e1, e2, e3, e4, e5, e6, e7, e8, e9, e10, e11, e12); arrayCopy(array, paramCount, others); return new RegularImmutableList<E>(ImmutableList.<E>nullCheckedList(array)); } And although it seems reasonable to have overloads for empty and single arguments (as they are going to use special instances), I cannot see the reason behind having all the others, when just the last one (with two fixed arguments plus the variable argument instead the dozen) seems to be enough. As I'm writing, one explanation that pops into my head is that the API pre-dates Java 1.5; and although the signatures would be source-level compatible, the binary interface would differ. Isn't it?

• Different behavior for REF CURSOR between Oracle 10g and 11g when unique index present?

  - by wweicker

  Description I have an Oracle stored procedure that has been running for 7 or so years both locally on development instances and on multiple client test and production instances running Oracle 8, then 9, then 10, and recently 11. It has worked consistently until the upgrade to Oracle 11g. Basically, the procedure opens a reference cursor, updates a table then completes. In 10g the cursor will contain the expected results but in 11g the cursor will be empty. No DML or DDL changed after the upgrade to 11g. This behavior is consistent on every 10g or 11g instance I've tried (10.2.0.3, 10.2.0.4, 11.1.0.7, 11.2.0.1 - all running on Windows). The specific code is much more complicated but to explain the issue in somewhat realistic overview: I have some data in a header table and a bunch of child tables that will be output to PDF. The header table has a boolean (NUMBER(1) where 0 is false and 1 is true) column indicating whether that data has been processed yet. The view is limited to only show rows in that have not been processed (the view also joins on some other tables, makes some inline queries and function calls, etc). So at the time when the cursor is opened, the view shows one or more rows, then after the cursor is opened an update statement runs to flip the flag in the header table, a commit is issued, then the procedure completes. On 10g, the cursor opens, it contains the row, then the update statement flips the flag and running the procedure a second time would yield no data. On 11g, the cursor never contains the row, it's as if the cursor does not open until after the update statement runs. I'm concerned that something may have changed in 11g (hopefully a setting that can be configured) that might affect other procedures and other applications. What I'd like to know is whether anyone knows why the behavior is different between the two database versions and whether the issue can be resolved without code changes. Update 1: I managed to track the issue down to a unique constraint. It seems that when the unique constraint is present in 11g the issue is reproducible 100% of the time regardless of whether I'm running the real world code against the actual objects or the following simple example. Update 2: I was able to completely eliminate the view from the equation. I have updated the simple example to show the problem exists even when querying directly against the table. Simple Example CREATE TABLE tbl1 ( col1 VARCHAR2(10), col2 NUMBER(1) ); INSERT INTO tbl1 (col1, col2) VALUES ('TEST1', 0); /* View is no longer required to demonstrate the problem CREATE OR REPLACE VIEW vw1 (col1, col2) AS SELECT col1, col2 FROM tbl1 WHERE col2 = 0; */ CREATE OR REPLACE PACKAGE pkg1 AS TYPE refWEB_CURSOR IS REF CURSOR; PROCEDURE proc1 (crs OUT refWEB_CURSOR); END pkg1; CREATE OR REPLACE PACKAGE BODY pkg1 IS PROCEDURE proc1 (crs OUT refWEB_CURSOR) IS BEGIN OPEN crs FOR SELECT col1 FROM tbl1 WHERE col1 = 'TEST1' AND col2 = 0; UPDATE tbl1 SET col2 = 1 WHERE col1 = 'TEST1'; COMMIT; END proc1; END pkg1; Anonymous Block Demo DECLARE crs1 pkg1.refWEB_CURSOR; TYPE rectype1 IS RECORD ( col1 vw1.col1%TYPE ); rec1 rectype1; BEGIN pkg1.proc1 ( crs1 ); DBMS_OUTPUT.PUT_LINE('begin first test'); LOOP FETCH crs1 INTO rec1; EXIT WHEN crs1%NOTFOUND; DBMS_OUTPUT.PUT_LINE(rec1.col1); END LOOP; DBMS_OUTPUT.PUT_LINE('end first test'); END; /* After creating this index, the problem is seen */ CREATE UNIQUE INDEX unique_col1 ON tbl1 (col1); /* Reset data to initial values */ TRUNCATE TABLE tbl1; INSERT INTO tbl1 (col1, col2) VALUES ('TEST1', 0); DECLARE crs1 pkg1.refWEB_CURSOR; TYPE rectype1 IS RECORD ( col1 vw1.col1%TYPE ); rec1 rectype1; BEGIN pkg1.proc1 ( crs1 ); DBMS_OUTPUT.PUT_LINE('begin second test'); LOOP FETCH crs1 INTO rec1; EXIT WHEN crs1%NOTFOUND; DBMS_OUTPUT.PUT_LINE(rec1.col1); END LOOP; DBMS_OUTPUT.PUT_LINE('end second test'); END; Example of what the output on 10g would be:   begin first test   TEST1   end first test   begin second test   TEST1   end second test Example of what the output on 11g would be:   begin first test   TEST1   end first test   begin second test   end second test Clarification I can't remove the COMMIT because in the real world scenario the procedure is called from a web application. When the data provider on the front end calls the procedure it will issue an implicit COMMIT when disconnecting from the database anyways. So if I remove the COMMIT in the procedure then yes, the anonymous block demo would work but the real world scenario would not because the COMMIT would still happen. Question Why is 11g behaving differently? Is there anything I can do other than re-write the code?

• Can we add new attribute or change type of existing attribute to a "Referenced Element"?

  - by JSteve

  In my XML schema I have an element being referenced tens of times by other elements but with different enumerated values for one of its attribute. For now, instead of creating this element in global space and referencing it later, I am creating a new instance wherever it is needed. This approach has increased my schema size enormously because of repeated creation of almost same element many times. It also may have adverse effect on efficiency of the schema. The only way that I see is to create element once and then reference it many times but my problem is: one of the attribute of this referenced element is required to have a different set of enumerations for each referencing element. My question is: Is it possible to to add an attribute to a "Referenced Element" in XML Schema? Something like this: <?xml version="1.0" encoding="UTF-8"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.myDomain.com" xmlns="http://www.myDomain.com" elementFormDefault="qualified"> <xs:simpleType name="myValues1"> <xs:restriction base="xs:string"> <xs:enumeration value="value1" /> <xs:enumeration value="value2" /> </xs:restriction> </xs:simpleType> <xs:element name="myElement"> <xs:complexType mixed="true"> <xs:attribute name="attr1" type="xs:string" /> <xs:attribute name="attr2" type="xs:string" /> </xs:complexType> </xs:element> <xs:element name="MainElement1"> <xs:complexType> <xs:sequence> <xs:element ref="myElement"> <xs:complexType> <xs:attribute name="myAtt" type="myValues1" /> </xs:complexType> </xs:element> </xs:sequence> <xs:attribute name="mainAtt1" /> </xs:complexType> </xs:element> </xs:schema> Or can we change type of an existing attribute of a "Referenced Element" in XML Schema? something like this: <?xml version="1.0" encoding="UTF-8"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.myDomain.com" xmlns="http://www.myDomain.com" elementFormDefault="qualified"> <xs:simpleType name="myValues1"> <xs:restriction base="xs:string"> <xs:enumeration value="value1" /> <xs:enumeration value="value2" /> </xs:restriction> </xs:simpleType> <xs:simpleType name="myValues2"> <xs:restriction base="xs:string"> <xs:enumeration value="value3" /> <xs:enumeration value="value4" /> </xs:restriction> </xs:simpleType> <xs:element name="myElement"> <xs:complexType mixed="true"> <xs:attribute name="attr1" type="xs:string" /> <xs:attribute name="attr2" type="xs:string" /> <xs:attribute name="myAtt" type="myValues1" /> </xs:complexType> </xs:element> <xs:element name="MainElement1"> <xs:complexType> <xs:sequence> <xs:element ref="myElement"> <xs:complexType> <xs:attribute name="myAtt" type="myValues2" /> </xs:complexType> </xs:element> </xs:sequence> <xs:attribute name="mainAtt1" /> </xs:complexType> </xs:element> </xs:schema>

• TStringList and TThread that does not free all of its memory

  - by VanillaH

  Version used: Delphi 7. I'm working on a program that does a simple for loop on a Virtual ListView. The data is stored in the following record: type TList=record Item:Integer; SubItem1:String; SubItem2:String; end; Item is the index. SubItem1 the status of the operations (success or not). SubItem2 the path to the file. The for loop loads each file, does a few operations and then, save it. The operations take place in a TStringList. Files are about 2mb each. Now, if I do the operations on the main form, it works perfectly. Multi-threaded, there is a huge memory problem. Somehow, the TStringList doesn't seem to be freed completely. After 3-4k files, I get an EOutofMemory exception. Sometimes, the software is stuck to 500-600mb, sometimes not. In any case, the TStringList always return an EOutofMemory exception and no file can be loaded anymore. On computers with more memory, it takes longer to get the exception. The same thing happens with other components. For instance, if I use THTTPSend from Synapse, well, after a while, the software cannot create any new threads because the memory consumption is too high. It's around 500-600mb while it should be, max, 100mb. On the main form, everything works fine. I guess the mistake is on my side. Maybe I don't understand threads enough. I tried to free everything on the Destroy event. I tried FreeAndNil procedure. I tried with only one thread at a time. I tried freeing the thread manually (no FreeOnTerminate...) No luck. So here is the thread code. It's only the basic idea; not the full code with all the operations. If I remove the LoadFile prodecure, everything works good. A thread is created for each file, according to a thread pool. unit OperationsFiles; interface uses Classes, SysUtils, Windows; type TOperationFile = class(TThread) private Position : Integer; TPath, StatusMessage: String; FileStringList: TStringList; procedure UpdateStatus; procedure LoadFile; protected procedure Execute; override; public constructor Create(Path: String; LNumber: Integer); end; implementation uses Form1; procedure TOperationFile.LoadFile; begin try FileStringList.LoadFromFile(TPath); // Operations... StatusMessage := 'Success'; except on E : Exception do StatusMessage := E.ClassName; end; end; constructor TOperationFile.Create(Path : String; LNumber: Integer); begin inherited Create(False); TPath := Path; Position := LNumber; FreeOnTerminate := True; end; procedure TOperationFile.UpdateStatus; begin FileList[Position].SubItem1 := StatusMessage; Form1.ListView4.UpdateItems(Position,Position); end; procedure TOperationFile.Execute; begin FileStringList:= TStringList.Create; LoadFile; Synchronize(UpdateStatus); FileStringList.Free; end; end. What could be the problem? I thought at one point that, maybe, too many threads are created. If a user loads 1 million files, well, ultimately, 1 million threads is going to be created -- although, only 50 threads are created and running at the same time. Thanks for your input.

• Multiple windows services in a single project = mystery

  - by Remoh

  I'm having a bizarre issue that I haven't seen before and I'm thinking it MUST be something simple that I'm not seeing in my code. I have a project with 2 windows services defined. One I've called DataSyncService, the other SubscriptionService. Both are added to the same project installer. Both use a timer control from System.Timers. If I start both services together, they seem to work fine. The timers elapse at the appropriate time and everything looks okay. However, if I start either service individually, leaving the other stopped, everything goes haywire. The timer elapses constantly and on the wrong service. In other words, if I start the DataSyncService, the SubscriptionService timer elapses over and over. ...which is obviously strange. The setup is similar to what I've done in the past so I'm really stumped. I even tried deleting both service and starting over but it doesn't seem to make a difference. At this point, I'm thinking I've made a simple error in the way I'm defining the services and my brain just won't let me see it. It must be creating some sort of threading issue that causes one service to race when the other is stopped. Here the code.... From Program.cs: static void Main() { ServiceBase[] ServicesToRun; ServicesToRun = new ServiceBase[] { new DataSyncService(), new SubscriptionService() }; ServiceBase.Run(ServicesToRun); } From ProjectInstaller.designer.cs: private void InitializeComponent() { this.serviceProcessInstaller1 = new System.ServiceProcess.ServiceProcessInstaller(); this.dataSyncInstaller = new System.ServiceProcess.ServiceInstaller(); this.subscriptionInstaller = new System.ServiceProcess.ServiceInstaller(); // // serviceProcessInstaller1 // this.serviceProcessInstaller1.Account = System.ServiceProcess.ServiceAccount.LocalSystem; this.serviceProcessInstaller1.Password = null; this.serviceProcessInstaller1.Username = null; // // dataSyncInstaller // this.dataSyncInstaller.DisplayName = "Data Sync Service"; this.dataSyncInstaller.ServiceName = "DataSyncService"; this.dataSyncInstaller.StartType = System.ServiceProcess.ServiceStartMode.Automatic; // // subscriptionInstaller // this.subscriptionInstaller.DisplayName = "Subscription Service"; this.subscriptionInstaller.ServiceName = "SubscriptionService"; this.subscriptionInstaller.StartType = System.ServiceProcess.ServiceStartMode.Automatic; // // ProjectInstaller // this.Installers.AddRange(new System.Configuration.Install.Installer[] { this.serviceProcessInstaller1, this.dataSyncInstaller, this.subscriptionInstaller}); } private System.ServiceProcess.ServiceProcessInstaller serviceProcessInstaller1; private System.ServiceProcess.ServiceInstaller dataSyncInstaller; private System.ServiceProcess.ServiceInstaller subscriptionInstaller; From DataSyncService.cs: public static readonly int _defaultInterval = 43200000; //log4net.ILog log; public DataSyncService() { InitializeComponent(); //log = LogFactory.Instance.GetLogger(this); } protected override void OnStart(string[] args) { timer1.Interval = _defaultInterval; //GetInterval(); timer1.Enabled = true; EventLog.WriteEntry("MyProj", "Data Sync Service Started", EventLogEntryType.Information); //log.Info("Data Sync Service Started"); } private void timer1_Elapsed(object sender, System.Timers.ElapsedEventArgs e) { EventLog.WriteEntry("MyProj", "Data Sync Timer Elapsed.", EventLogEntryType.Information); } private void InitializeComponent() { this.timer1 = new System.Timers.Timer(); ((System.ComponentModel.ISupportInitialize)(this.timer1)).BeginInit(); // // timer1 // this.timer1.Enabled = true; this.timer1.Elapsed += new System.Timers.ElapsedEventHandler(this.timer1_Elapsed); // // DataSyncService // this.ServiceName = "DataSyncService"; ((System.ComponentModel.ISupportInitialize)(this.timer1)).EndInit(); } From SubscriptionService: public static readonly int _defaultInterval = 300000; //log4net.ILog log; public SubscriptionService() { InitializeComponent(); } protected override void OnStart(string[] args) { timer1.Interval = _defaultInterval; //GetInterval(); timer1.Enabled = true; EventLog.WriteEntry("MyProj", "Subscription Service Started", EventLogEntryType.Information); //log.Info("Subscription Service Started"); } private void timer1_Elapsed(object sender, System.Timers.ElapsedEventArgs e) { EventLog.WriteEntry("MyProj", "Subscription Service Time Elapsed", EventLogEntryType.Information); } private void InitializeComponent() //in designer { this.timer1 = new System.Timers.Timer(); ((System.ComponentModel.ISupportInitialize)(this.timer1)).BeginInit(); // // timer1 // this.timer1.Enabled = true; this.timer1.Elapsed += new System.Timers.ElapsedEventHandler(this.timer1_Elapsed); // // SubscriptionService // this.ServiceName = "SubscriptionService"; ((System.ComponentModel.ISupportInitialize)(this.timer1)).EndInit(); } Again, the problem is that the timer1_elapsed handler runs constantly when only one of the services is started. And it's the handler on the OPPOSITE service. Anybody see anything?

• Object oriented n-tier design. Am I abstracting too much? Or not enough?

  - by max

  Hi guys, I'm building my first enterprise grade solution (at least I'm attempting to make it enterprise grade). I'm trying to follow best practice design patterns but am starting to worry that I might be going too far with abstraction. I'm trying to build my asp.net webforms (in C#) app as an n-tier application. I've created a Data Access Layer using an XSD strongly-typed dataset that interfaces with a SQL server backend. I access the DAL through some Business Layer Objects that I've created on a 1:1 basis to the datatables in the dataset (eg, a UsersBLL class for the Users datatable in the dataset). I'm doing checks inside the BLL to make sure that data passed to DAL is following the business rules of the application. That's all well and good. Where I'm getting stuck though is the point at which I connect the BLL to the presentation layer. For example, my UsersBLL class deals mostly with whole datatables, as it's interfacing with the DAL. Should I now create a separate "User" (Singular) class that maps out the properties of a single user, rather than multiple users? This way I don't have to do any searching through datatables in the presentation layer, as I could use the properties created in the User class. Or would it be better to somehow try to handle this inside the UsersBLL? Sorry if this sounds a little complicated... Below is the code from the UsersBLL: using System; using System.Data; using PedChallenge.DAL.PedDataSetTableAdapters; [System.ComponentModel.DataObject] public class UsersBLL { private UsersTableAdapter _UsersAdapter = null; protected UsersTableAdapter Adapter { get { if (_UsersAdapter == null) _UsersAdapter = new UsersTableAdapter(); return _UsersAdapter; } } [System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Select, true)] public PedChallenge.DAL.PedDataSet.UsersDataTable GetUsers() { return Adapter.GetUsers(); } [System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Select, false)] public PedChallenge.DAL.PedDataSet.UsersDataTable GetUserByUserID(int userID) { return Adapter.GetUserByUserID(userID); } [System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Select, false)] public PedChallenge.DAL.PedDataSet.UsersDataTable GetUsersByTeamID(int teamID) { return Adapter.GetUsersByTeamID(teamID); } [System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Select, false)] public PedChallenge.DAL.PedDataSet.UsersDataTable GetUsersByEmail(string Email) { return Adapter.GetUserByEmail(Email); } [System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Insert, true)] public bool AddUser(int? teamID, string FirstName, string LastName, string Email, string Role, int LocationID) { // Create a new UsersRow instance PedChallenge.DAL.PedDataSet.UsersDataTable Users = new PedChallenge.DAL.PedDataSet.UsersDataTable(); PedChallenge.DAL.PedDataSet.UsersRow user = Users.NewUsersRow(); if (UserExists(Users, Email) == true) return false; if (teamID == null) user.SetTeamIDNull(); else user.TeamID = teamID.Value; user.FirstName = FirstName; user.LastName = LastName; user.Email = Email; user.Role = Role; user.LocationID = LocationID; // Add the new user Users.AddUsersRow(user); int rowsAffected = Adapter.Update(Users); // Return true if precisely one row was inserted, // otherwise false return rowsAffected == 1; } [System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Update, true)] public bool UpdateUser(int userID, int? teamID, string FirstName, string LastName, string Email, string Role, int LocationID) { PedChallenge.DAL.PedDataSet.UsersDataTable Users = Adapter.GetUserByUserID(userID); if (Users.Count == 0) // no matching record found, return false return false; PedChallenge.DAL.PedDataSet.UsersRow user = Users[0]; if (teamID == null) user.SetTeamIDNull(); else user.TeamID = teamID.Value; user.FirstName = FirstName; user.LastName = LastName; user.Email = Email; user.Role = Role; user.LocationID = LocationID; // Update the product record int rowsAffected = Adapter.Update(user); // Return true if precisely one row was updated, // otherwise false return rowsAffected == 1; } [System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Delete, true)] public bool DeleteUser(int userID) { int rowsAffected = Adapter.Delete(userID); // Return true if precisely one row was deleted, // otherwise false return rowsAffected == 1; } private bool UserExists(PedChallenge.DAL.PedDataSet.UsersDataTable users, string email) { // Check if user email already exists foreach (PedChallenge.DAL.PedDataSet.UsersRow userRow in users) { if (userRow.Email == email) return true; } return false; } } Some guidance in the right direction would be greatly appreciated!! Thanks all! Max

• Adding java source (.java files) to test jar in Maven

  - by user320550

  Hi all, I'm making use of my pom.xml and am was able to generate the jar for src/main/java (say app.jar) as well as for src/test/java (say app-test.jar). I was also able to include my java sources as part of the app.jar (i.e. have both my .class as well as my .java files in the jar). However for my app-test.jar, i'm not able to include my .java files in it. This is my pom.xml: <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.mycompany.app</groupId> <artifactId>my-app</artifactId> <version>1.0-SNAPSHOT</version> <packaging>jar</packaging> <name>my-app</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> </dependencies> <build> <resources> <resource> <directory>src/main/java</directory> </resource> </resources> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <version>2.3.1</version> <executions> <execution> <phase>package</phase> <goals> <goal>test-jar</goal> </goals> <configuration> <includes> <include>src/test/java</include> </includes> </configuration> </execution> </executions> </plugin> </plugins> </build> </project> Any help would be appreciated.

• How can I Include Multiples Tables in my linq to entities eager loading using mvc4 C#

  - by EBENEZER CURVELLO

  I have 6 classes and I try to use linq to Entities to get the SiglaUF information of the last deeper table (in the view - MVC). The problem is I receive the following error: "The ObjectContext instance has been disposed and can no longer be used for operations that require a connection." The view is like that: > @model IEnumerable<DiskPizzaDelivery.Models.EnderecoCliente> > @foreach (var item in Model) { > @Html.DisplayFor(modelItem => item.CEP.Cidade.UF.SiglaUF) > } The query that i use: var cliente = context.Clientes .Include(e => e.Enderecos) .Include(e1 => e1.Enderecos.Select(cep => cep.CEP)) .SingleOrDefault(); The question is: How Can I improve this query to pre loading (eager loading) "Cidade" and "UF"? See below the classes: public partial class Cliente { [Key] [DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)] public int IdCliente { get; set; } public string Email { get; set; } public string Senha { get; set; } public virtual ICollection<EnderecoCliente> Enderecos { get; set; } } public partial class EnderecoCliente { public int IdEndereco { get; set; } public int IdCliente { get; set; } public string CEPEndereco { get; set; } public string Numero { get; set; } public string Complemento { get; set; } public string PontoReferencia { get; set; } public virtual Cliente Cliente { get; set; } public virtual CEP CEP { get; set; } } public partial class CEP { public string CodCep { get; set; } public string Tipo_Logradouro { get; set; } public string Logradouro { get; set; } public string Bairro { get; set; } public int CodigoUF { get; set; } public int CodigoCidade { get; set; } public virtual Cidade Cidade { get; set; } } public partial class Cidade { public int CodigoCidade { get; set; } public string NomeCidade { get; set; } public int CodigoUF { get; set; } public virtual ICollection<CEP> CEPs { get; set; } public virtual UF UF { get; set; } public virtual ICollection<UF> UFs { get; set; } } public partial class UF { public int CodigoUF { get; set; } public string SiglaUF { get; set; } public string NomeUF { get; set; } public int CodigoCidadeCapital { get; set; } public virtual ICollection<Cidade> Cidades { get; set; } public virtual Cidade Cidade { get; set; } } var cliente = context.Clientes .Where(c => c.Email == email) .Where(c => c.Senha == senha) .Include(e => e.Enderecos) .Include(e1 => e1.Enderecos.Select(cep => cep.CEP)) .SingleOrDefault(); Thanks!

• How do I update mysql database when posting form without using hidden inputs?

  - by user1322707

  I have a "members" table in mysql which has approximately 200 field names. Each user is given up to 7 website templates with 26 different values they can insert unique data into for each template. Each time they create a template, they post the form with the 26 associated values. These 26 field names are the same for each template, but are differentiated by an integer at the end, ie _1, _2, ... _7. In the form submitting the template, I have a variable called $pid_sum which is inserted at the end of each field name to identify which template they are creating. For instance: <form method='post' action='create.template.php'> <input type='hidden' name='address_1' value='address_1'> <input type='hidden' name='city_1' value='city_1'> <input type='hidden' name='state_1' value='state_1'> etc... <input type='hidden' name='address_1' value='address_2'> <input type='hidden' name='city_1' value='city_2'> <input type='hidden' name='state_1' value='state_2'> etc... <input type='hidden' name='address_2' value='address_3'> <input type='hidden' name='city_2' value='city_3'> <input type='hidden' name='state_2' value='state_3'> etc... <input type='hidden' name='address_2' value='address_4'> <input type='hidden' name='city_2' value='city_4'> <input type='hidden' name='state_2' value='state_4'> etc... <input type='hidden' name='address_2' value='address_5'> <input type='hidden' name='city_2' value='city_5'> <input type='hidden' name='state_2' value='state_5'> etc... <input type='hidden' name='address_2' value='address_6'> <input type='hidden' name='city_2' value='city_6'> <input type='hidden' name='state_2' value='state_6'> etc... <input type='hidden' name='address_2' value='address_7'> <input type='hidden' name='city_2' value='city_7'> <input type='hidden' name='state_2' value='state_7'> etc... // Visible form user fills out in creating their template ($pid_sum converts // into an integer 1-7, depending on what template they are filling out) <input type='' name='address_$pid_sum'> <input type='' name='city_$pid_sum'> <input type='' name='state_$pid_sum'> etc... <input type='submit' name='save_button' id='save_button' value='Save Settings'> <form> Each of these need updated in a hidden input tag with each form post, or the values in the database table (which aren't submitted with the form) get deleted. So I am forced to insert approximately 175 hidden input tags with every creation of 26 new values for one of the 7 templates. Is there a PHP function or command that would enable me to update all these values without inserting 175 hidden input tags within each form post? Here is the create.template.php file which the form action calls: <?php $q=new Cdb; $t->set_file("content", "create_template.html"); $q2=new CDB; $query="SELECT menu_category FROM menus WHERE link='create.template.ag.php'"; $q2->query($query); $toall=0; if ($q2->nf()<1) { $toall=1; } while ($q2->next_record()) { if ($q2->f('menu_category')=="main") { $toall=1; } } if ($toall==0) { get_logged_info(); $q2=new CDB; $query="SELECT id FROM menus WHERE link='create_template.php'"; $q2->query($query); $q2->next_record(); $query="SELECT membership_id FROM menu_permissions WHERE menu_item='".$q2->f("id")."'"; $q2->query($query); while ($q2->next_record()) { $permissions[]=$q2->f("membership_id"); } if (count($permissions)>0) { $error='<center><font color="red"><b>You do not have access to this area!<br><br>Upgrade your membership level!</b></font></center>'; foreach ($permissions as $value) { if ($value==$q->f("membership_id")) { $error=''; break; } } if ($error!="") { die("$error"); } } } $member_id=$q->f("id"); $pid=$q->f("pid"); $pid_sum = $pid +1; $first_name=$q->f("first_name"); $last_name=$q->f("last_name"); $email=$q->f("email"); echo " // THIS IS WHERE THE HTML FORM GOES "; replace_tags_t($q->f("id"), $t); ?>

• Error 0x800f0922 installing .NET 3.5 on Windows 8

  - by Benjamin Nolan

  I'm trying to install .NET 3.5 on my Windows 8 box and it keeps throwing Error 0x800f0922 at me. From what I've read on answers.microsoft.com and StackOverflow I gather the easiest way to fix this is to perform a system refresh, however this will remove all software I've installed from discs. I've just moved house, so I'd rather not do that as I don't know where all the installation media actually are for a lot of my software, so if possible I'd prefer to track down where the problem is actually occurring. (Also, I have a LOT of software installed. It'd take me a long time to reinstall it all, and I unfortunately haven't got that time.) The on-demand error screen sends me to KB2734782 (can't link it as I'm <10 rep), which doesn't help much. When I run this DISM line from the StackOverflow post: Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:C:\Windows\WinSxS /LimitAccess I get the following output on the terminal: Microsoft Windows [Version 6.2.9200] (c) 2012 Microsoft Corporation.

• Where do I find scripts generated by SharePoint MCMS Migration Profiles

  - by HipCzeck

  I am attempting to migrate data from an Microsoft Content Management Server (MCMS) 2002 instance into a new Microsoft Office Sharepoint Server (MOSS) 2007 installation using the Manage Microsoft Content Management Server Migration Profiles tool in the Operations space of MOSS Central Administration. When analyzing the profile, I receive 4 warnings, all of which may be safely ignored, but when I actually execute the migration profile, I get the same warnings and an additional error with a description of: Line 6: Incorrect syntax near ';'. I have seen this error numerous times when mucking about in SQL Server and recognize it as a Transact SQL error message, but can't find the actual SQL statement that is being executed so that I may determine the source of the error. EDIT: After enabling verbose logging on the MCMS 2002 Migration category, and poring through the Unified Logging Service (ULS) logs, I received a more complete stack trace at the point of the error, and a couple more anomalies listed below. Anomalies: The following is an abbreviated listing from the ULS logs around the time of the pre-migration analysis. 01 MCMS 2002 Migration Verbose Start ConnectionCheck 02 MCMS 2002 Migration Verbose End ConnectionCheck 03 MCMS 2002 Migration Verbose Start DatabaseCheck 04 MCMS 2002 Migration High Extra table SiteDeployLock will not be migrated 05 MCMS 2002 Migration High Analysis: Extra index PK__SiteDeployLock__05D8E0BE 06 MCMS 2002 Migration Verbose End DatabaseCheck 07 MCMS 2002 Migration Medium Pre-migration analysis: RootCheckTask is skipped because database check is blocked. 08 MCMS 2002 Migration Medium Pre-migration analysis: RightsGroupNameCheckTask is skipped because database check is blocked. 09 MCMS 2002 Migration Medium Pre-migration analysis: InvalidNameCheckTask is skipped because database check is blocked. 10 MCMS 2002 Migration Medium Pre-migration analysis: LeafNameCheckTask is skipped because database check is blocked. 11 MCMS 2002 Migration Medium Pre-migration analysis: LeafLengthCheckTask is skipped because database check is blocked. 12 MCMS 2002 Migration Medium Pre-migration analysis: TemplateNameCheckTask is skipped because database check is blocked. 13 MCMS 2002 Migration Medium Pre-migration analysis: TemplateCollisionCheckTask is skipped because database check is blocked. 14 MCMS 2002 Migration Medium Pre-migration analysis: PlaceholderCheckTask is skipped because database check is blocked. 15 MCMS 2002 Migration Medium Pre-migration analysis: CheckedOutItemsCheckTask is skipped because database check is blocked. 16 MCMS 2002 Migration Medium Pre-migration analysis: SubmittedItemsCheckTask is skipped because database check is blocked. 17 MCMS 2002 Migration Medium Pre-migration analysis: DeletedItemsCheckTask is skipped because database check is blocked. 18 MCMS 2002 Migration Medium Pre-migration analysis: UserCheckTask is skipped because database check is blocked. 19 MCMS 2002 Migration Medium Pre-migration analysis: FileSizeCheckTask is skipped because database check is blocked. 20 MCMS 2002 Migration Medium Pre-migration analysis: HostHeaderMapCheckTask is skipped because database check is blocked. 21 MCMS 2002 Migration Verbose Start Server check 22 MCMS 2002 Migration Verbose End Server check 23 MCMS 2002 Migration Verbose Start Server emptyness check 24 MCMS 2002 Migration Verbose End Server emptyness check 25 MCMS 2002 Migration Medium PreMigrationAnalyzer: Dry run starts 26 MCMS 2002 Migration Verbose CleanLockProcedure: start. 27 MCMS 2002 Migration High CleanLockProcedure: connection system lock is null 28 MCMS 2002 Migration Verbose Finished all tasks 29 MCMS 2002 Migration High PreMigrationAnalyzer ends with True 30 MCMS 2002 Migration Verbose Migration profile status is changed to AnalysisPassed Specifically, the two High level alerts on lines 4 and 5 are reflected in the migration report as warnings when running Pre-migration Analysis or running the migration profile. In addition, two other warnings appear in the migration report indicating two tables containing data (LayoutProperty and NodeLayout) that should be empty. According to the documentation, warnings are not sufficient cause to stop migration from occurring. Other anomalies are on lines 7-20 indicating a series of tests that are skipped because database check is blocked. The ULS doesn't give any additional warnings to indicate that the database check was blocked or exited in exceptional circumstances. After switching the profile from pre-migration analysis to exporting, there is one medium level warning that LastChangeTime is not set or incorrect. (null).

That appears to have happened on the SharePoint server. Are there any other locations I should investigate that might tell me where to find the source of the error?

• Cannot Start Nginx Compiled from Source

  - by Jason Alan Kennedy

  I am trying to compile Nginx from source based on the original compiled Nginx server running on my DigitalOcean server ( Ubuntu-14.04 64x ) but with a few extra modules. I can get everything installed smoothly but I can not get it to start. I am sure the ini is correct because I copied the original source off the current running Nginx server [ Even though I see that Nginx now adds the ini when compiling fron source ]. Below is the [ lengthy process ] that I am performing - add sorry but I wanted to be thorough for those who are in need of the info ]. Because I am a newB to Nginx, I am sure I am missing something or just have it all wrong. If you may look over what I have done and see if you spot anything I need/need to change, I will greatly appreciate it. Thnx! With the original Nginx server still running: I check the current/running Nginx configuration so I can build the new Nginx instance the same but with the added modules: nginx -V # The out-put: configure arguments: --with-cc-opt='-g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2' --with-ld-opt='-Wl,-Bsymbolic-functions -Wl,-z,relro' --prefix=/usr/share/nginx --conf-path=/etc/nginx/nginx.conf --http-log-path=/var/log/nginx/access.log --error-log-path=/var/log/nginx/error.log --lock-path=/var/lock/nginx.lock --pid-path=/run/nginx.pid --http-client-body-temp-path=/var/lib/nginx/body --http-fastcgi-temp-path=/var/lib/nginx/fastcgi --http-proxy-temp-path=/var/lib/nginx/proxy --http-scgi-temp-path=/var/lib/nginx/scgi --http-uwsgi-temp-path=/var/lib/nginx/uwsgi --with-debug --with-pcre-jit --with-ipv6 --with-http_ssl_module --with-http_stub_status_module --with-http_realip_module --with-http_addition_module --with-http_dav_module --with-http_geoip_module --with-http_gzip_static_module --with-http_image_filter_module --with-http_spdy_module --with-http_sub_module --with-http_xslt_module NOTE: The configure arguments below return errors during 'make' so I removed them.

Also with nginx -V and its not installed??? I reboot the system too and still nothing. So I am not sure what is wrong here. The ini was copied over from the old server along with all the other config files after deleting the old files. When I opened the new compiled files, the nginx default data was present so I replaced them with my old original data prior to starting the new server for the first time. Also to be safe, I rm /etc/nginx/sites-enabled/default and symlinked with ln -s /etc/nginx/sites-available/default /etc/nginx/sites-enabled/default with no errors and I verified that the data was in the sites-enabled/default file. I don't think the server really/fully installed because of the nginx -V result: The program 'nginx' can be found in the following packages: * nginx-core * nginx-extras * nginx-full * nginx-light * nginx-naxsi Try: apt-get install <selected package> Do/should I apt-get install nginx-1.7.4 ?? Or what package do I use being that its a custom package and make install earlier did nothing?? If you need to see the conf files I copied over from the old to the custom server, LMK and I'll post them. Again your help here would be appreciated!

• apache2 doesn't start with location

  - by Geod24

  I have a small domain, which I use only for personal purposes. I'm the main user, and have at most 3-4 users at the same time. I use apache2 with passenger to serve redmine. So I start with an empty apache2: root@xxxxx:/home/# service apache2 start [ ok ] Starting web server: apache2. root@xxxxx:/home/# a2dissite Your choices are: Which site(s) do you want to disable (wildcards ok)? Then enable my site, and restart (not reload) apache2: root@xxxxx:/home/# a2ensite 200-redmine Enabling site 200-redmine. To activate the new configuration, you need to run: service apache2 reload root@xxxxx:/home/# service apache2 restart [FAIL] Restarting web server: apache2 failed! [warn] The apache2 instance did not start within 20 seconds. Please read the log files to discover problems ... (warning). root@xxxxx:/home/# service apache2 restart [FAIL] Restarting web server: apache2 failed! [warn] There are processes named 'apache2' running which do not match your pid file which are left untouched in the name of safety, Please review the situation by hand. ... (warning). root@xxxxx:/home/# pidof apache2 20948 Here's my 200-redmine.conf: PerlLoadModule Apache::Redmine <VirtualHost *:80> ServerName redmine.xxxxx.xxx DocumentRoot /var/www/redmine/public/ ErrorLog ${APACHE_LOG_DIR}/redmine.error.log CustomLog ${APACHE_LOG_DIR}/redmine.access.log common MaxRequestLen 20971520 <Directory "/var/www/redmine/public/"> Options Indexes ExecCGI FollowSymLinks Order allow,deny Allow from all AllowOverride all </Directory> SetEnv GIT_PROJECT_ROOT /opt/git/ SetEnv GIT_HTTP_EXPORT_ALL ScriptAlias /git/ /usr/lib/git-core/git-http-backend/ <Location /git> PerlAuthenHandler Apache::Authn::Redmine::authen_handler PerlAccessHandler Apache::Authn::Redmine::access_handler AuthType Basic Require valid-user AuthName "Redmine Git Repository" RedmineDSN "DBI:mysql:database=redmine;host=localhost:3306" RedmineDbUser "redmine" RedmineDbPass "password" RedmineCacheCredsMax 50 </Location> </VirtualHost> Now if I comment out the ScriptAlias / stuff, it works ! In addition, starting the server with 200-redmine disabled, then enabling it works. But apache2 will die randomly. Plus the location doesn't work.

• Openvpn plugin openvpn-auth-ldap does not bind to Active Directory

  - by Selivanov Pavel

  I'm trying to configure OpenVPN with openvpn-auth-ldap plugin to authorize users via Active Directory LDAP. When I use the same server config without plugin option, and add client config with generated client key and cert, connection is successful, so problem is in the plugin. server.conf: plugin /usr/lib/openvpn/openvpn-auth-ldap.so "/etc/openvpn-test/openvpn-auth-ldap.conf" port 1194 proto tcp dev tun keepalive 10 60 topology subnet server 10.0.2.0 255.255.255.0 tls-server ca ca.crt dh dh1024.pem cert server.crt key server.key #crl-verify crl.pem persist-key persist-tun user nobody group nogroup verb 3 mute 20 openvpn-auth-ldap.conf: <LDAP> URL ldap://dc1.domain:389 TLSEnable no BindDN cn=bot_auth,cn=Users,dc=domain Password bot_auth Timeout 15 FollowReferrals yes </LDAP> <Authorization> BaseDN "cn=Users,dc=domain" SearchFilter "(sAMAccountName=%u)" RequireGroup false # <Group> # BaseDN "ou=groups,dc=mycompany,dc=local" # SearchFilter "(|(cn=developers)(cn=artists))" # MemberAttribute uniqueMember # </Group> </Authorization> Top-level domain in AD is used by historical reasons.
