  • isolate web servers on intranet with dfl-800

    - by microchasm
    I administer a small network (10 users). I'm getting ready to deploy a internal webapp that will be hosted and accessed locally only. There are about 10 users on the network (192.168.111.0/24), a win2k3 server, apache (RHEL), and Mysql (RHEL), and various miscellaneous peripheries. I'd like to isolate the apache and sql boxes into a seperate area of the lan to keep things easier to maintain/grow. I've been reading about vlans, subnets, etc.. I'm not clear, however, which would be the best solution for our setup. Thanks for any tips and or advice.

  • Offloading Cable Modem operations to Router

    - by Matt
    I may be crazy here, but I seem to recall a conversation in the past stating that it was possible to offload some of the operations taken by one's cable modem to one's router. The logic was that since the cable modem is often equipped with a cheaper processor as it is supplied by your provider, that it often chokes even crashes when you start a torrent or something else with a lot of connections. I seem to recall that some routers offered the ability to take some of the modem's operations. Is this possible or have I imagined the whole thing? I ask because my modem seems to have many issues when I start torrents.

  • The Oracle Cash Management Secret Very Few Customers Know About

    - by Theresa Hickman
    Did you know that Oracle Cash Management has a robust positioning feature? I had no idea. I was under the mistaken impression that Oracle Cash Management only did bank statement reconciliations. It seems I am not alone. In fact, many Oracle Financials customers are also not aware of this even though it is delivered for free with the Oracle Financials license. Even better, last week, Oracle released an enhancement to Oracle Cash Management for Release 12 that will greatly help customers with their cash positioning needs. As we all know, credit is tight these days. Companies need better visibility of their cash and other liquidity positions to make better use of their cash resources. Today, many customers are managing their cash positions manually using spreadsheets. We also hear how many of them are maintaining larger than normal balances in numerous bank accounts because they just do not have the visibility, and therefore the comfort they need. Although spreadsheets may work in the short-term, they are not the best way to manage your cash positions for the long-term especially if you have dozens, or even hundreds of bank and brokerage accounts. Also, spreadsheets are a lot more risky because they can be overwritten, deleted, difficult to audit, etc. With the newly enhanced positioning feature in Oracle Cash Management, customers can manage their daily cash positions using an excel-like interface that is very flexible and user-configurable. You can link the worksheet to an unlimited number of bank accounts to automatically retrieve your opening balances, the current/intra-day cash inflows and outflows, as well as your expected cash flows from your Fx, Investment and Debt positions if you have Oracle's Treasury module . Oracle Cash Management also has direct integration with Oracle Receivables, Oracle Payables, and Payroll, which adds to the comprehensive picture of what's happening with your organizations' cash in real-time. Here's a screen shot of what the cash positioning page looks like: View image As you can see, your Treasurers can obtain a holistic view of all cash positions across any number of bank accounts as well as other sources of cash flow movements. Depending on how they manage their accounts, they can also use this feature to initiate or monitor bank account sweeps or transfers between their zero balance accounts (ZBA) or cash pools. The cash position worksheet provide drill down for more detail and the ability to manually enter items directly into the worksheet for even greater flexibility and control. The enhancements to this feature were released last week. The following list the patches for Release 12.0.6 and 12.1.1: For more information, visit the following website. http://launch.oracle.com.

  • Checking if subfolders exist linux

    - by laura
    I'm trying to check if a folder has any subfolders without iterating through its children, in Linux. The closest I've found so far is using ftw and stopping at the first subfolder - or using scandir and filtering through the results. Both, are, however, an overkill for my purposes, I simply want a yes/no. On Windows, this is done by calling SHGetFileInfo and then testing dwAttributes & SFGAO_HASSUBFOLDER on the returned structure. Is there such an option on Linux?

  • Alternative Django Authenication

    - by pq
    Need to integrate Django with an existing authentication system. That system has it's own database, API, login/logout,edit profile web pages and cookie. (I may have to add a few additional profile fields stored/updated locally) What's the proper approach to substitute the out-of-the-box authentication in Django?

  • JDBC query to Oracle

    - by Harish
    Hi, We are planning to migrate our DB to Oracle.We need to manually check each of the embedded SQL is working in Oracle as few may follow different SQL rules.Now my need is very simple. I need to browse through a file which may contain queries like this. String sql = "select * from test where name="+test+"and age="+age; There are nearly 1000 files and each file has different kind of queries like this where I have to pluck the query alone which I have done through an unix script.But I need to convert these Java based queries to Oracle compatible queries. ie. select * from test where name="name" and age="age" Basically I need to check the syntax of the queries by this.I have seen something like this in TOAD but I have more than 1000 files and can't manually change each one.Is there a way? I will explain more i the question is not clear

  • What's the difference? eval() or just call the function directly?

    - by question_about_the_problem
    I'm not php expert and I don't know what's the difference(1) between a and b. a.)eval('return "'.base64_decode("encoded_text").'";') b.)base64_decode("encoded_text") -I THINK, a is php code and b is just string. And my other question is: What is the difference(2) between c and d? c.)eval('return "'.base64_decode("encoded_text").'";') d.)eval(base64_decode("encoded_text")) So I have 2 questions. Who can answer/help ? Thanks.

  • validating wsdl/schema using cxf

    - by SGB
    I am having a hard time getting cxf to validate an xml request that my service creates for a 3rd party. My project uses maven. Here is my project structure Main Module : + Sub-Module1 = Application + sub-Module2 = Interfaces In Interfaces, inside src/main/resources I have my wsdl and xsd. so, src/main/resources + mywsdl.wsdl. + myschema.xsd The interface submodule is listed as a dependency in the Application-sub-module. inside Application sub-module, there is a cxsf file in src/maim/resources. <jaxws:client name="{myTargerNameSpaceName}port" createdFromAPI="true"> <jaxws:properties> <entry key="schema-validation-enabled" value="true" /> </jaxws:properties> </jaxws:client> AND:. <jaxws:endpoint name="{myTargetNameSpaceName}port" wsdlLocation="/mywsdl.wsdl" createdFromAPI="true"> <jaxws:properties> <entry key="schema-validation-enabled" value="true" /> </jaxws:properties> </jaxws:endpoint> I tried changing the "name="{myTargetNameSpaceName}port" to "name="{myEndPointName}port" But to no anvil. My application works. But it just do not validate the xml I am producing that has to be consumed by a 3rd party application. I would like to get the validation working, so that any request that I send would be a valid one. Any suggestions?

  • JQuery class selectors like $(.someClass) are case sensitive?

    - by Justin Grant
    Given this HTML: <div class="OpenIDSelector">some text</div> Why does this JQuery selector match it on some browsers and some pages, but not on others? $('.OpenIdSelector) NOTE: I ran into this problem and solved it myself, but it was annoying and I didn't find it on StackOverflow already, so I'm posting it as a Q&A pair so someone else won't waste an hour like I did.

  • Removed MAMP from OS X, dyld still using MAMP libraries

    - by dizzee
    When I try and use a populator or sphinx on a Ruby app I keep receiving dyld errors. I used to use MAMP on OS X Leopard but since I've upgraded to Snow Leopard and am now using standalone MySQL (10.5 64-bit). $ rake ts:index Would return dyld: Library not loaded: /Applications/MAMP/Library/lib/mysql/libmysqlclient.15.dylib Referenced from: /usr/local/bin/indexer Reason: image not found rake aborted! Even though to remove MAMP I just deleted the /Applications/MAMP directory. But it still looks like dylib has references to it. I've tried running: $ sudo update_dyld_shared_cache -verify and restarting but the problem still persists. OS X 10.6.1, MySQL 5.0.85 (x86_64)

  • SSIS - Parallel Execution of Tasks - How efficient is it?

    - by Randy Minder
    I am building an SSIS package that will contain dozens of Sequence tasks. Each Sequence task will contain three tasks. One to truncate a destination table and remove indexes on the table, another to import data from a source table, and a third to add back indexes to the destination table. My question is this. I currently have nine of these Sequences tasks built, and none are dependent on any of the others. When I execute the package, SSIS seems to do a pretty good job of determining which tasks in which Sequence to execute, which, by the way, appears to be quite random. As I continue adding more Sequences, should I attempt to be smarter about how SSIS should execute these Sequences, or is SSIS smart enough to do it itself? Thanks.

  • Recursive mocking with Rhino-Mocks

    - by jaspernygaard
    Hi I'm trying to unittest several MVP implementations and can't quite figure out the best way to mock the view. I'll try to boil it down. The view IView consists e.g. of a property of type IControl. interface IView { IControl Control1 { get; } IControl Control2 { get; } } interface IControl { bool Enabled { get; set; } object Value { get; set; } } My question is whether there's a simple way to setup the property behavior for Enabled and Value on the IControl interface members on the IView interface - like recursive mocking a guess. I would rather not setup expectations for all my properties on the view (quite a few on each view). Thanks in advance

  • QuickReport.ExportToFilter throws "stack overflow" error when used in TWebModule

    - by M Schenkel
    I have a web application using the TWebModule component. It runs as a module on Apache. The code below throws a "Stack Overflow" error on the ExportToFilter. The same exact code works fine from a Winforms Application and even a service for that matter. I have seen other discussions on this which indicate it has something to do with threading. var mFileName: String; AExportFilter:; begin mFileName := 'c:\temp\calendar.pdf'; AExportFilter:=TQRPDFDocumentFilter.Create(mFileName); try WebSchdHistCalendarForm := TWebSchdHistCalendarForm.create(nil); WebSchdHistCalendarForm.quickrep1.ShowProgress := False; WebSchdHistCalendarForm.quickrep1.ExportToFilter(AExportFilter ); finally AExportFilter.Free; WebSchdHistCalendarForm.Free; end;

  • Getting results in a result set from dynamic SQL in Oracle

    - by msorens
    This question is similar to a couple others I have found on StackOverflow, but the differences are signficant enough to me to warrant a new question, so here it is: I want to obtain a result set from dynamic SQL in Oracle and then display it as a result set in a SqlDeveloper-like tool, just as if I had executed the dynamic SQL statement directly. This is straightforward in SQL Server, so to be concrete, here is an example from SQL Server that returns a result set in SQL Server Management Studio or Query Explorer: EXEC sp_executesql N'select * from countries' Or more properly: DECLARE @stmt nvarchar(100) SET @stmt = N'select * from countries' EXEC sp_executesql @stmt The question "How to return a resultset / cursor from a Oracle PL/SQL anonymous block that executes Dynamic SQL?" addresses the first half of the problem--executing dynamic SQL into a cursor. The question "How to make Oracle procedure return result sets" provides a similar answer. Web search has revealed many variations of the same theme, all addressing just the first half of my question. I found this post explaining how to do it in SqlDeveloper, but that uses a bit of functionality of SqlDeveloper. I am actually using a custom query tool so I need the solution to be self-contained in the SQL code. This custom query tool similarly does not have the capability to show output of print (dbms_output.put_line) statements; it only displays result sets. Here is yet one more possible avenue using 'execute immediate...bulk collect', but this example again renders the results with a loop of dbms_output.put_line statements. This link attempts to address the topic but the question never quite got answered there either. Assuming this is possible, I will add one more condition: I would like to do this without having to define a function or procedure (due to limited DB permissions). That is, I would like to execute a self-contained PL/SQL block containing dynamic SQL and return a result set in SqlDeveloper or a similar tool. So to summarize: I want to execute an arbitrary SQL statement (hence dynamic SQL). The platform is Oracle. The solution must be a PL/SQL block with no procedures or functions. The output must be generated as a canonical result set; no print statements. The output must render as a result set in SqlDeveloper without using any SqlDeveloper special functionality. Any suggestions?

  • Mysql - Join matches and non-matches

    - by jwzk
    This is related to my other question: http://stackoverflow.com/questions/2579249/managing-foreign-keys I am trying to join the table of matches and non-matches. So I have a list of interests, a list of users, and a list of user interests. I want the query to return all interests, whether the user has the interest or not (should be null in that case), only where the user = x. Every time I get the query working its only matching interests that the user specifically has, instead of all interests whether they have it or not.

  • Prototypejs .evalJSON not returning object

    - by Pselus
    I have this JSON (which validates according to JSONLint): [ { "BugCount":"2", "BugTitle":"C:\\INETPUB\\WWWROOT\\CLUBREADY2\\TRAINERS\\../Connections/LTC.asp", "ErrLine":"141", "BugID":"702" }, { "BugCount":"1", "BugTitle":"/admin/ajax_logagreementsig.asp", "ErrLine":"0", "BugID":"1322" }, ] However, when I run data = json.evalJSON on it I get some problems. If I run .evalJSON(true) (to sanitize) an error happens within prototype saying "json" is undefined. The same happens if I do .evalJSON(). If I do .evalJSON with no parenthesis, then data is just an empty object and no error happens. Is there something wrong with my JSON?
