  • PMDB Block Size Choice

    - by Brian Diehl
    Choosing a block size for the P6 PMDB database is not a difficult task. In fact, taking the default of 8k is going to be just fine. Block size is one of those things that is always hotly debated. Everyone has their personal preference and can sight plenty of good reasons for their choice. To add to the confusion, Oracle supports multiple block sizes withing the same instance. So how to decide and what is the justification? Like most OLTP systems, Oracle Primavera P6 has a wide variety of data. A typical table's average row size may be less than 50 bytes or upwards of 500 bytes. There are also several tables with BLOB types but the LOB data tends not to be very large. It is likely that no single block size would be perfect for every table. So how to choose? My preference is for the 8k (8192 bytes) block size. It is a good compromise that is not too small for the wider rows, yet not to big for the thin rows. It is also important to remember that database blocks are the smallest unit of change and caching. I prefer to have more, individual "working units" in my database. For an instance with 4gb of buffer cache, an 8k block will provide 524,288 blocks of cache. The following SQL*Plus script returns the average, median, min, and max rows per block. column "AVG(CNT)" format 999.99 set verify off select avg(cnt), median(cnt), min(cnt), max(cnt), count(*) from ( select dbms_rowid.ROWID_RELATIVE_FNO(rowid) , dbms_rowid.ROWID_BLOCK_NUMBER(rowid) , count(*) cnt from &tab group by dbms_rowid.ROWID_RELATIVE_FNO(rowid) , dbms_rowid.ROWID_BLOCK_NUMBER(rowid) ) Running this for the TASK table, I get this result on a database with an 8k block size. Each activity, on average, has about 19 rows per block. Enter value for tab: task AVG(CNT) MEDIAN(CNT) MIN(CNT) MAX(CNT) COUNT(*) -------- ----------- ---------- ---------- ---------- 18.72 19 3 28 415917 I recommend an 8k block size for the P6 transactional database. All of our internal performance and scalability test are done with this block size. This does not mean that other block sizes will not work. Instead, like many other parameters, this is the safest choice.

  • ADF Real World Developers Guide Book Review

    - by Grant Ronald
    I'm half way through my review of "Oracle ADF Real World Developer's Guide" by Jobinesh Purushothaman - unfortunately some work deadlines de-railed me from having completed my review by now but here goes.  First thing, Jobinesh works in the Oracle Product Management team with me, so is a colleague. That declaration aside, its clear that this is someone who has done the "real world" side of ADF development and that comes out in the book. In this book he addresses both the newbies and the experience developers alike.  He introduces the ADF building blocks like entity objects and view obejcts, but also goes into some of the nitty gritty details as well.  There is a pro and con to this approach; having only just learned about an entity or view object, you might then be blown away by some of the lower details of coding or lifecycle.  In that respect, you might consider this a book which you could read 3 or 4 times; maybe skipping some elements in the first read but on the next read you have a better grounding to learn the more advanced topics. One of the key issues he addresses is breaking down what happens behind the scenes.  At first, this may not seem important since you trust the framework to do everything for you - but having an understanding of what goes on is essential as you move through development.  For example, page 58 he explains the full lifecycle of what happens when you execute a query.  I think this is a great feature of his book. You see this elsewhere, for example he explains the full lifecycle of what goes on when a page is accessed : which files are involved,the JSF lifecycle etc. He also sprinkes the book with some best practices and advice which go beyond the standard features of ADF and really hits the mark in terms of "real world" advice. So in summary, this is a great ADF book, well written and covering a mass of information.  If you are brand new to ADF its still valid given it does start with the basics.  But you might want to read the book 2 or 3 times, skipping the advanced stuff on the first read.  For those who have some basics already then its going to be an awesome way to cement your knowledge and take it to the next levels.  And for the ADF experts, you are still going to pick up some great ADF nuggets.  Advice: every ADF developer should have one!

  • Oracle: How to update master with newest row from detail table?

    - by LukLed
    We have two tables: Vehicle: Id, RegistrationNumber, LastAllocationUserName, LastAllocationDate, LastAllocationId Allocations: Id, VehicleId, UserName, Date What is the most efficient (easiest) way to update every row in Vehicle table with newest allocation? In SQL Server I would use UPDATE FROM and join every Vehicle with newest Allocation. Oracle doesn't have UPDATE FROM. How do you do it in Oracle?

  • Customer count map (Google maps?)

    - by David Hamilton
    I have a two column list consisting of a US zipcode and a count (number of customers in this case). I want to put this data onto a map. Would Google maps API be a good fit for this? It seems like this would be a common enough type of problem to already have an existing (preferably Java based) solution without having to re-invent the wheel. Any suggestions?

  • How to determine which version of Oracle Client is being used from the server.

    - by Robert Love
    Using Oracle 10g. ( 10.2.0.4 ) Possibly by looking at either logs or system tables is there a way to determine which version of the oracle client each connection is using. Our systems initially had 8.1.7 Clients, and then 9.X clients. We attempted to manually locate all machines that had older clients and upgrade them to to 10.2 Clients. We are seeking a method to audit (from the server) if we were successful in upgrading all of our client machines.

  • We have a Solaris 9 server running Oracle 10G and have been getting memory consumption errors for a few weeks now

    - by another_netadmin
    We recently upgraded our Enterprise application and everything worked ok until one weekend when we did a server reboot, ever since then we have run into memory errors. The server has 4GB of physical memory installed and the kernel parameters are set to the following (/etc/system). I'm not an Oracle guy so I'm not sure where to start looking but any informaiton is greatly appreciated. Thanks in advance. There are two databases running on this server, one is a production database and the other is a pre-production database.

  • Magento My Account Layout XML Problem

    - by Remy
    Hi there, I'm having issues getting the customer.xml layout file to work properly for the customer's "my account" pages. The navigation links and the previously ordered items that are usually on the left hand side of the page won't show up on the page, but if I change the reference name to "content" in the xml file, it shows up (except it's obviously then on the right hand side). I've checked the template it's referencing (2columns-left.phtml), and the getChildHtml('left') is there in the correct position. The block that's causing the problem: <customer_account> <!-- Mage_Customer --> <reference name="root"> <action method="setTemplate"><template>page/2columns-left.phtml</template></action> </reference> <reference name="left"> <action method="unsetChild"><name>catalog.navigation.all</name></action> <action method="unsetChild"><name>callout.sendcard</name></action> <action method="unsetChild"><name>callout.specialorder</name></action> <block type="customer/account_navigation" name="customer_account_navigation" before="-" template="customer/account/navigation.phtml"> <action method="addLink" translate="label" module="customer"><name>account</name><path>customer/account/</path><label>Account Dashboard</label></action> <action method="addLink" translate="label" module="customer"><name>account_edit</name><path>customer/account/edit/</path><label>Account Information</label></action> <action method="addLink" translate="label" module="customer"><name>address_book</name><path>customer/address/</path><label>Address Book</label></action> </block> <block type="sales/reorder_sidebar" name="sale.reorder.sidebar" as="reorder" template="sales/reorder/sidebar.phtml"/> <remove name="tags_popular"/> </reference> </customer_account> This was basically copied straight over from another one of our sites where this works 100%. I've tried everything I can think of (changing the name of the reference in both the template and the layout xml, for example) to no avail. The templates that the layout is referencing are obviously working because they do show up when put into the "content" area. This installation of magento is version 1.3.1.1. I appreciate any advice you have to give me... *Update: I tried changing the reference to "global_messages", and it doesn't show there either. It only seems to work in the "content" section.* Update 2: These are the results of using the "showLayout=page" query string on the page when used with Alan Storm's very handy debugging module (which you'll find in his answer below). <?xml version="1.0"?> <layout><block type="page/html" name="root" output="toHtml" template="page/3columns.phtml"> <block type="page/html_head" name="head" as="head">

  • Hibernate: how to call a stored function returning a varchar?

    - by Péter Török
    I am trying to call a legacy stored function in an Oracle9i DB from Java using Hibernate. The function is declared like this: create or replace FUNCTION Transferlocation_Fix (mnemonic_code IN VARCHAR2) RETURN VARCHAR2 After several failed tries and extensive googling, I found this thread on the Hibernate forums which suggested a mapping like this: <sql-query name="TransferLocationFix" callable="true"> <return-scalar column="retVal" type="string"/> select Transferlocation_Fix(:mnemonic) as retVal from dual </sql-query> My code to execute it is Query query = session.getNamedQuery("TransferLocationFix"); query.setParameter("mnemonic", "FC3"); String result = (String) query.uniqueResult(); and the resulting log is DEBUG (org.hibernate.jdbc.AbstractBatcher:366) - - about to open PreparedStatement (open PreparedStatements: 0, globally: 0) DEBUG (org.hibernate.SQL:401) - - select Transferlocation_Fix(?) as retVal from dual TRACE (org.hibernate.jdbc.AbstractBatcher:484) - - preparing statement TRACE (org.hibernate.type.StringType:133) - - binding 'FC3' to parameter: 2 TRACE (org.hibernate.type.StringType:133) - - binding 'FC3' to parameter: 2 java.lang.NullPointerException at oracle.jdbc.ttc7.TTCAdapter.newTTCType(TTCAdapter.java:300) at oracle.jdbc.ttc7.TTCAdapter.createNonPlsqlTTCColumnArray(TTCAdapter.java:270) at oracle.jdbc.ttc7.TTCAdapter.createNonPlsqlTTCDataSet(TTCAdapter.java:231) at oracle.jdbc.ttc7.TTC7Protocol.doOall7(TTC7Protocol.java:1924) at oracle.jdbc.ttc7.TTC7Protocol.parseExecuteDescribe(TTC7Protocol.java:850) at oracle.jdbc.driver.OracleStatement.doExecuteQuery(OracleStatement.java:2599) at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(OracleStatement.java:2963) at oracle.jdbc.driver.OraclePreparedStatement.executeUpdate(OraclePreparedStatement.java:658) at oracle.jdbc.driver.OraclePreparedStatement.execute(OraclePreparedStatement.java:736) at com.mchange.v2.c3p0.impl.NewProxyCallableStatement.execute(NewProxyCallableStatement.java:3044) at org.hibernate.dialect.Oracle8iDialect.getResultSet(Oracle8iDialect.java:379) at org.hibernate.jdbc.AbstractBatcher.getResultSet(AbstractBatcher.java:193) at org.hibernate.loader.Loader.getResultSet(Loader.java:1784) at org.hibernate.loader.Loader.doQuery(Loader.java:674) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:236) at org.hibernate.loader.Loader.doList(Loader.java:2220) at org.hibernate.loader.Loader.listIgnoreQueryCache(Loader.java:2104) at org.hibernate.loader.Loader.list(Loader.java:2099) at org.hibernate.loader.custom.CustomLoader.list(CustomLoader.java:289) at org.hibernate.impl.SessionImpl.listCustomQuery(SessionImpl.java:1695) at org.hibernate.impl.AbstractSessionImpl.list(AbstractSessionImpl.java:142) at org.hibernate.impl.SQLQueryImpl.list(SQLQueryImpl.java:152) at org.hibernate.impl.AbstractQueryImpl.uniqueResult(AbstractQueryImpl.java:811) at com.my.project.SomeClass.method(SomeClass.java:202) ...

  • HSDPA modem only working on certain USB ports

    - by nabulke
    Depending on which USB port I use to connect my HSDPA modem, the network manager will connect to the internet or not. I used to work (i.e. established a internet connection automatically) on all ports, but over time it simply stopped on some ports. lsusb output in all cases looks like that (Device ID varies depending on USB port): Bus 001 Device 009: ID 12d1:1003 Huawei Technologies Co., Ltd. E220 HSDPA Modem / E270 HSDPA/HSUPA Modem Any ideas what could cause this behaviour? What can I do to fix this? ADDED One additional information about the modem: if connected via USB it will be available as as harddrive AND as a HSDPA modem (kind of a duality...). In the error case, it will only be shown as a harddrive.

In the first post, JMS Step 1 - How to Create a Simple JMS Queue in Weblogic Server 11g we looked at how to create a JMS queue and its dependent objects in WebLogic Server. In the previous post, JMS Step 2 - Using the QueueSend.java Sample Program to Send a Message to a JMS Queue I showed how to write a message to that JMS queue using the QueueSend.java sample program. In this article, we will use a similar sample, the QueueReceive.java program to read the message from that queue. Please review the previous posts if you have not already done so, as they contain prerequisites for executing the sample in this article. 1. Source code The following java code will be used to read the message(s) from the JMS queue. As with the previous example, it is based on a sample program shipped with the WebLogic Server installation. The sample is not installed by default, but needs to be installed manually using the WebLogic Server Custom Installation option, together with many, other useful samples. You can either copy-paste the following code into your editor, or install all the samples. The knowledge base article in My Oracle Support: How To Install WebLogic Server and JMS Samples in WLS 10.3.x (Doc ID 1499719.1) describes how to install the samples. QueueReceive.java package examples.jms.queue; import java.util.Hashtable; import javax.jms.*; import javax.naming.Context; import javax.naming.InitialContext; import javax.naming.NamingException; /** * This example shows how to establish a connection to * and receive messages from a JMS queue. The classes in this * package operate on the same JMS queue. Run the classes together to * witness messages being sent and received, and to browse the queue * for messages. This class is used to receive and remove messages * from the queue. * * @author Copyright (c) 1999-2005 by BEA Systems, Inc. All Rights Reserved. */ public class QueueReceive implements MessageListener { // Defines the JNDI context factory. public final static String JNDI_FACTORY="weblogic.jndi.WLInitialContextFactory"; // Defines the JMS connection factory for the queue. public final static String JMS_FACTORY="jms/TestConnectionFactory"; // Defines the queue. public final static String QUEUE="jms/TestJMSQueue"; private QueueConnectionFactory qconFactory; private QueueConnection qcon; private QueueSession qsession; private QueueReceiver qreceiver; private Queue queue; private boolean quit = false; /** * Message listener interface. * @param msg message */ public void onMessage(Message msg) { try { String msgText; if (msg instanceof TextMessage) { msgText = ((TextMessage)msg).getText(); } else { msgText = msg.toString(); } System.out.println("Message Received: "+ msgText ); if (msgText.equalsIgnoreCase("quit")) { synchronized(this) { quit = true; this.notifyAll(); // Notify main thread to quit } } } catch (JMSException jmse) { System.err.println("An exception occurred: "+jmse.getMessage()); } } /** * Creates all the necessary objects for receiving * messages from a JMS queue. * * @param ctx JNDI initial context * @param queueName name of queue * @exception NamingException if operation cannot be performed * @exception JMSException if JMS fails to initialize due to internal error */ public void init(Context ctx, String queueName) throws NamingException, JMSException { qconFactory = (QueueConnectionFactory) ctx.lookup(JMS_FACTORY); qcon = qconFactory.createQueueConnection(); qsession = qcon.createQueueSession(false, Session.AUTO_ACKNOWLEDGE); queue = (Queue) ctx.lookup(queueName); qreceiver = qsession.createReceiver(queue); qreceiver.setMessageListener(this); qcon.start(); } /** * Closes JMS objects. * @exception JMSException if JMS fails to close objects due to internal error */ public void close()throws JMSException { qreceiver.close(); qsession.close(); qcon.close(); } /** * main() method. * * @param args WebLogic Server URL * @exception Exception if execution fails */ public static void main(String[] args) throws Exception { if (args.length != 1) { System.out.println("Usage: java examples.jms.queue.QueueReceive WebLogicURL"); return; } InitialContext ic = getInitialContext(args[0]); QueueReceive qr = new QueueReceive(); qr.init(ic, QUEUE); System.out.println( "JMS Ready To Receive Messages (To quit, send a \"quit\" message)."); // Wait until a "quit" message has been received. synchronized(qr) { while (! qr.quit) { try { qr.wait(); } catch (InterruptedException ie) {} } } qr.close(); } private static InitialContext getInitialContext(String url) throws NamingException { Hashtable env = new Hashtable(); env.put(Context.INITIAL_CONTEXT_FACTORY, JNDI_FACTORY); env.put(Context.PROVIDER_URL, url); return new InitialContext(env); } } 2. How to Use This Class 2.1 From the file system on Linux This section describes how to use the class from the file system of a WebLogic Server installation. Log in to a machine with a WebLogic Server installation and create a directory to contain the source and code matching the package name, e.g. span$HOME/examples/jms/queue. Copy the above QueueReceive.java file to this directory. Set the CLASSPATH and environment to match the WebLogic server environment. Go to $MIDDLEWARE_HOME/user_projects/domains/base_domain/bin  and execute . ./setDomainEnv.sh Collect the following information required to run the script: The JNDI name of the JMS queue to use In the WebLogic server console > Services > Messaging > JMS Modules > Module name, (e.g. TestJMSModule) > JMS queue name, (e.g. TestJMSQueue) select the queue and note its JNDI name, e.g. jms/TestJMSQueue The JNDI name of the connection factory to use to connect to the queue Follow the same path as above to get the connection factory for the above queue, e.g. TestConnectionFactory and its JNDI name e.g. jms/TestConnectionFactory The URL and port of the WebLogic server running the above queue Check the JMS server for the above queue and the managed server it is targeted to, for example soa_server1. Now find the port this managed server is listening on, by looking at its entry under Environment > Servers in the WLS console, e.g. 8001 The URL for the server to be passed to the QueueReceive program will therefore be t3://host.domain:8001 e.g. t3://jbevans-lx.de.oracle.com:8001 Edit Queue Receive .java and enter the above queue name and connection factory respectively under ... public final static String JMS_FACTORY="jms/TestConnectionFactory"; ... public final static String QUEUE="jms/TestJMSQueue"; ... Compile Queue Receive .java using javac Queue Receive .java Go to the source’s top-level directory and execute it using java examples.jms.queue.Queue Receive   t3://jbevans-lx.de.oracle.com:8001 This will print a message that it is ready to receive messages or to send a “quit” message to end. The program will read all messages in the queue and print them to the standard output until it receives a message with the payload “quit”. 2.2 From JDeveloper The steps from JDeveloper are the same as those used for the previous program QueueSend.java, which is used to send a message to the queue. So we won't repeat them here. Please see the previous blog post at JMS Step 2 - Using the QueueSend.java Sample Program to Send a Message to a JMS Queue and apply the same steps in that example to the QueueReceive.java program. This concludes the example. In the following post we will create a BPEL process which writes a message based on an XML schema to the queue.

  • Issue 15: Introducing David Callaghan

    - by rituchhibber
        DAVID'S VIEW INTRODUCING DAVID CALLAGHAN David Callaghan Senior Vice President, Oracle EMEA Alliances and Channels David Callaghan is the Senior Vice President, Alliances & Channels, for Oracle EMEA. He is responsible for all elements of the Oracle Partner Network across the region and leads Oracle as it continues to deliver customer success through the alignment of Oracle's applications and hardware engineered to work together. As I reflect on our last quarter, I thank all our partners for your continued commitment and expertise in embracing the unique opportunity we have before us. The ability to engage with hardware, applications and technology is a real differentiator. We have been able to engage with deep specialization in individual products for some time, which has brought tremendous benefits. But now we can strengthen this further with the broad stack specialization that Oracle on Oracle brings. Now is the time to make that count. While customers are finishing spending this year's budget and planning their spend for the next calendar year, it is now that we need to build the quality opportunities and pipeline for the rest of the year. We have OpenWorld just around the corner with its compelling new product announcements and environment to engage customers at all levels. Make sure you use this event, and every opportunity it brings. In the next quarter you can expect to see targeted 'value creation' campaigns driven by Oracle, and I encourage you to exploit these where they will have greatest impact. My team will be engaging closely with their Oracle sales colleagues to help them leverage the tremendous value you bring, and to develop their ability to work effectively and independently with you, our partners. My team and I are all relentlessly committed to achieving partner, and customer, satisfaction to demonstrate the value of the Passion for Partnering that we all share. With best regards David Back to the welcome page
