  • Forms&Reports upgrade characterset issues

    - by Lukasz Romaszewski
    Hello,This quick post is based on my findings during recent IMC workshops, especially those related to upgrading the Forms 6i/9i/10g applications to Forms 11g platform. The upgrade process itself is pretty straightforward and it basically requires recompiling your Forms application with a latest version of frmcmp tool. For some cases though, especially when you migrate from Forms 6i which is a client-server architecture to a 3-tier web solution (Forms 11g), you need to rewrite some parts of your code to make it run on new platform. The things you need to change range from reimplementing (using webutil library) typical client-site functionality like local IO operation, access to WinAPI, invoking DLLs etc. to changing deprecated or obsolete APIs like RUN_PRODUCT to RUN_REPORT_OBJECT. To automate those changes Oracle provides complete Java API  which allows you to manipulate the code and structure of you modules (JDAPI). To make it even easier we can use Forms Migration Assistant tool (written in Java using JDAPI) which is able to replace all occurrences of old API entries with their 11g equivalents or warn you when the replacement is not possible. You can also add your own replacement definitions in the search_replace.properties file. But you need to be aware of some issues that can be encountered using this tool. First of all if you are using some hard-coded text inside your triggers you may notice that after processing them by the Migration Assistant tool the national characters may be lost. This is due to the fact that you need to explicitly tell Java application (which MA really is) what kind of characterset it should use to read those text properly. In order to do that just add to a script calling MA the following line:  export JAVA_TOOL_OPTIONS=-Dfile.encoding=<JAVA_ISO_ENCODING>  when the particular encoding must match the NLS_LANG in your Forms Builder environment (for example for Polish characterset you need to use ISO-8859-2).Second issue you can encounter related to national charactersets is lack of national symbols in you reports after migration. This can be solved by adding appropriate NLS_LANG entry in your reports environment. Sometimes instead of particular characterset you see "Greek characters" in your reports. This is just default font used by reports engine instead of the one defined in your report. To solve it you must copy fonts definitions from your old environment (e.g. Forms 10g installation) to appropriate directory in new installation (usually AFM folder). For more information about this and other issues please refer to https://support.oracle.com/CSP/main/article?cmd=show&type=NOT&doctype=BULLETIN&id=1297012.1at My Oracle Support site. That's all for today, stay tuned for more posts on this topic! Lukasz

  • Implementing the Reactive Manifesto with Azure and AWS

    - by Elton Stoneman
    Originally posted on: http://geekswithblogs.net/EltonStoneman/archive/2013/10/31/implementing-the-reactive-manifesto-with-azure-and-aws.aspxMy latest Pluralsight course, Implementing the Reactive Manifesto with Azure and AWS has just been published! I’d planned to do a course on dual-running a messaging-based solution in Azure and AWS for super-high availability and scale, and the Reactive Manifesto encapsulates exactly what I wanted to do. A “reactive” application describes an architecture which is inherently resilient and scalable, being event-driven at the core, and using asynchronous communication between components. In the course, I compare that architecture to a classic n-tier approach, and go on to build out an app which exhibits all the reactive traits: responsive, event-driven, scalable and resilient. I use a suite of technologies which are enablers for all those traits: ASP.NET SignalR for presentation, with server push notifications to the user Messaging in the middle layer for asynchronous communication between presentation and compute Azure Service Bus Queues and Topics AWS Simple Queue Service AWS Simple Notification Service MongoDB at the storage layer for easy HA and scale, with minimal locking under load. Starting with a couple of console apps to demonstrate message sending, I build the solution up over 7 modules, deploying to Azure and AWS and running the app across both clouds concurrently for the whole stack - web servers, messaging infrastructure, message handlers and database servers. I demonstrating failover by killing off bits of infrastructure, and show how a reactive app deployed across two clouds can survive machine failure, data centre failure and even whole cloud failure. The course finishes by configuring auto-scaling in AWS and Azure for the compute and presentation layers, and running a load test with blitz.io. The test pushes masses of load into the app, which is deployed across four data centres in Azure and AWS, and the infrastructure scales up seamlessly to meet the load – the blitz report is pretty impressive: That’s 99.9% success rate for hits to the website, with the potential to serve over 36,000,000 hits per day – all from a few hours’ build time, and a fairly limited set of auto-scale configurations. When the load stops, the infrastructure scales back down again to a minimal set of servers for high availability, so the app doesn’t cost much to host unless it’s getting a lot of traffic. This is my third course for Pluralsight, with Nginx and PHP Fundamentals and Caching in the .NET Stack: Inside-Out released earlier this year. Now that it’s out, I’m starting on the fourth one, which is focused on C#, and should be out by the end of the year.

  • Less than 50 Lines of Code to Create a Java Palette in NetBeans

    - by Geertjan
    Want to drag and drop Java code snippets into the palette, in the same way as can be done for HTML files? If so, create a new module and add a class with the content below and you're done. You'll be able to select a piece of Java code, drag it into the palette (Ctrl-Shift-8 to open it), where you'll be able to set a name, tooltip, and icons for the snippet, and then you'll be able to drag it out of the palette into any Java files you like. The palette content is persisted across restarts of the IDE. package org.netbeans.modules.javasourcefilepalette; import java.io.IOException; import javax.swing.Action; import org.netbeans.api.editor.mimelookup.MimeRegistration; import org.netbeans.spi.palette.DragAndDropHandler; import org.netbeans.spi.palette.PaletteActions; import org.netbeans.spi.palette.PaletteController; import org.netbeans.spi.palette.PaletteFactory; import org.openide.util.Exceptions; import org.openide.util.Lookup; import org.openide.util.datatransfer.ExTransferable; public class JavaSourceFileLayerPaletteFactory { private static PaletteController palette = null; @MimeRegistration(mimeType = "text/x-java", service = PaletteController.class) public static PaletteController createPalette() { try { if (null == palette) { return PaletteFactory.createPalette( //Folder: "JavaPalette", //Palette Actions: new PaletteActions() { @Override public Action[] getImportActions() {return null;} @Override public Action[] getCustomPaletteActions() {return null;} @Override public Action[] getCustomCategoryActions(Lookup lkp) {return null;} @Override public Action[] getCustomItemActions(Lookup lkp) {return null;} @Override public Action getPreferredAction(Lookup lkp) {return null;} }, //Palette Filter: null, //Drag and Drop Handler: new DragAndDropHandler(true) { @Override public void customize(ExTransferable et, Lookup lkp) {} }); } } catch (IOException ex) { Exceptions.printStackTrace(ex); } return null; } } In my layer file, I have this content: <folder name="JavaPalette"> <folder name="Snippets"/> </folder> That's all. Run the module. Open a Java source file and the palette will automatically open. Drag some code into the palette and a dialog will pop up asking for some details like display name and icons. Then the snippet will be in the palette and you'll be able to drag and drop it anywhere you like. Use the Palette Manager, which is automatically integrated, to add new categories and show/hide palette items. Related blog entry, for which the above is a big simplification: Drag/Drop Snippets into Palette .

  • Monitor the Weather from Your Windows 7 Taskbar

    - by Asian Angel
    Keeping up with the weather forecast can be hard when you are extra busy with work. If you need a simple but nice looking way to integrate weather monitoring into your Taskbar then join us as we look at WeatherBar. Setting Up & Using WeatherBar To get started unzip the following files, place them in an appropriate “Program Files Folder”, and create a shortcut. When you start WeatherBar for the first time you will be presented with the following window and a random/default location. To get WeatherBar set up for your location there are only two settings to adjust (using the “Pencil & Gear Buttons”). Clicking on the “Pencil Button” will open up this small window…enter the name of your location and click “OK”. Next click on the “Gear Button” where you can choose the “Update Interval” and “Measurement Format” that best suits your needs. Click “OK” when finished and WeatherBar will be ready to go. That definitely looks nice. When you are finished viewing this window minimize it to the “Taskbar Icon” instead of clicking on the “Close Button”…otherwise the entire app will close. Left click on the “Taskbar Icon” to bring the window back up… Hovering the mouse over the “Taskbar Icon” provides a nice thumbnail of the weather forecast. Right clicking on the “Taskbar Icon” will display a nice mini forecast. Conclusion While WeatherBar may not be for everyone it does provide a nice easy way to monitor the weather from your “Taskbar” without taking up a lot of room.

  • What are the drawbacks of sending XML to browsers and let them apply XSLT?

    - by MainMa
    Context Working as a freelance developer, I often made websites completely based on XSLT. In other words, on every request, an XML file is generated, containing everything we need to know about the page content: the name of the user currently logged in, the top menu entries, if this menu is dynamic/configurable, the text to display in a specific area of the page, etc. Then XSL process (caches, etc.) it to HTML/XHTML page to send to the browser. It has a good point to make it easier to create small-scale websites, especially with PHP. It is a sort of template engine, but which I prefer to other template engines because it's much more powerful than most of template engines, and because I know it better and like it. It is also possible, when need, to give an access to raw XML data on demand for an automated access, without the need to create separate APIs. Of course, it will fail completely on any medium-scale or large-scale website, since, even with good caching techniques, XSL still degrades overall website performance and requires more CPU serverside. Question Modern browsers have the ability to take an XML file and to transform it with an associated XSL file declared in XML like <?xml-stylesheet href="demo.xslt" type="text/xsl"?>. Firefox 3 can do it. Internet Explorer 8 can do it too. It means that it is possible to migrate XSL processing from the server to the client side for 50% of users (according on browser statistics on several websites where I may want to implement this). It means that those 50% of users will receive only the XML file at each request, thus reducing their and server's bandwidth (XML file being much shorter than its processed HTML analog), and reducing server's CPU usage. What are the drawbacks of this technique? I thought about several ones, but it doesn't apply in this situation: Difficult implementation and the need to choose, based on the browser request, when to send raw XML and when to transform it to HTML instead. Obviously, the system will not be much more difficult then the actual one. The only change to make is to add XSL file link to every XML, and to add a browser check. More IO and bandwidth usage, since the XSLT file will be downloaded by the browsers, instead of being cached by the server. I don't think it will be a problem, since XSLT file will be cached by the browsers (like images, or CSS, or JavaScript files are cached actually). Possibly some problems on client side, like maybe problems when saving a page in some browsers. Difficulty to debug code: it is impossible to obtain an HTML source the browser is actually using, since the only displayed source is the downloaded XML. On the other hand, I rarely go look at HTML code on client side, and in most cases, it is unusable directly (whitespace being removed).

  • Java word scramble game [closed]

    - by Dan
    I'm working on code for a word scramble game in Java. I know the code itself is full of bugs right now, but my main focus is getting a vector of strings broken into two separate vectors containing hints and words. The text file that the strings are taken from has a colon separating them. So here is what I have so far. public WordApp() { inputRow = new TextInputBox(); inputRow.setLocation(200,100); phrases = new Vector <String>(FileUtilities.getStrings()); v_hints = new Vector<String>(); v_words = new Vector<String>(); textBox = new TextBox(200,100); textBox.setLocation(200,200); textBox.setText(scrambled + "\n\n Time Left: \t" + seconds/10 + "\n Score: \t" + score); hintBox = new TextBox(200,200); hintBox.setLocation(300,400); hintBox.hide(); Iterator <String> categorize = phrases.iterator(); while(categorize.hasNext()) { int index = phrases.indexOf(":"); String element = categorize.next(); v_words.add(element.substring(0,index)); v_hints.add(element.substring(index +1)); phrases.remove(index); System.out.print(index); } The FileUtilities file was given to us by the pofessor, here it is. import java.util.*; import java.io.*; public class FileUtilities { private static final String FILE_NAME = "javawords.txt"; //------------------ getStrings ------------------------- // // returns a Vector of Strings // Each string is of the form: word:hint // where word contains no spaces. // The words and hints are read from FILE_NAME // // public static Vector<String> getStrings ( ) { Vector<String> words = new Vector<String>(); File file = new File( FILE_NAME ); Scanner scanFile; try { scanFile = new Scanner( file); } catch ( IOException e) { System.err.println( "LineInput Error: " + e.getMessage() ); return null; } while ( scanFile.hasNextLine() ) { // read the word and follow it by a colon String s = scanFile.nextLine().trim().toUpperCase() + ":"; if( s.length()>1 && scanFile.hasNextLine() ) { // append the hint and add to collection s+= scanFile.nextLine().trim(); words.add(s); } } // shuffle Collections.shuffle(words); return words; } }

  • why client can not receive message from server (java) [migrated]

    - by user1745931
    I have just started learning java. I modified the client side code for a server/client communication program, by creating two threads for the client side, main thread for receiving user's input, and inputThread for receiving server's response. I am sure that server has sent the response to client, however, no response message is obtain at client. Here is my code. Can anyone help me to figure it out? Thanks package clientnio; import java.net.*; import java.nio.*; import java.io.*; import java.nio.channels.*; import java.util.Scanner; public class ClientNIO { public static int bufferLen = 50; public static SocketChannel client; public static ByteBuffer writeBuffer; public static ByteBuffer readBuffer; public static void main(String[] args) { writeBuffer = ByteBuffer.allocate(bufferLen); readBuffer = ByteBuffer.allocate(bufferLen); try { SocketAddress address = new InetSocketAddress("localhost",5505); System.out.println("Local address: "+ address); client=SocketChannel.open(address); client.configureBlocking(false); //readBuffer.flip(); new inputThread(readBuffer); /* String a="asdasdasdasddffasfas"; writeBuffer.put(a.getBytes()); writeBuffer.clear(); int d=client.write(writeBuffer); writeBuffer.flip(); */ while (true) { InputStream inStream = System.in; Scanner scan = new Scanner(inStream); if (scan.hasNext()==true) { String inputLine = scan.nextLine(); writeBuffer.put(inputLine.getBytes()); //writeBuffer.clear(); System.out.println(writeBuffer.remaining()); client.write(writeBuffer); System.out.println("Sending data: "+new String(writeBuffer.array())); writeBuffer.flip(); Thread.sleep(300); } } } catch(Exception e) { System.out.println(e); } } } class inputThread extends Thread { private ByteBuffer readBuffer; public inputThread(ByteBuffer readBuffer1) { System.out.println("Receiving thread starts."); this.readBuffer = readBuffer1; start(); } @Override public void run() { try { while (true) { readBuffer.flip(); int i=ClientNIO.client.read(readBuffer); if(i>0) { byte[] b=readBuffer.array(); System.out.println("Receiving data: "+new String(b)); //client.close(); //System.out.println("Connection closed."); //break; } Thread.sleep(100); } } catch (Exception e) { System.out.println(e); } } }

  • SQL Saturday 194 - Exeter

    - by Dave Ballantyne
    Many kudos goes to Jonathan and Annette Allen and the others on the team for confirming SQL Saturday 194 in Exeter on the 8th and 9th of March.  The event home page is here http://www.sqlsaturday.com/194/eventhome.aspx and I delighted that myself and Dave Morrison will be presenting a full day pre-con on the 8th on favourite subjects “TSQL and Internals”. Here is the full abstract : TSQL and internals - When faced with performance issues there are many lines of attack. Tuning the engine itself can get you so far, however for maximum effect you need to understand how the engine and how it translates SQL statements into performable actions. This is not a simple task, it is a massive task to deal with a multi-table join and the number of permutations can be immense. To back up this knowledge, we can create better performing TSQL and understand the impact that is has upon the engine and recognize the pitfalls and gotcha’s that exist in SQLServer. Ultimately, there is no ‘best way’ to perform a single task only many variations of ‘it depends’ , but now we can pick the most appropriate option for the required dataload. Over the years, there have been many myths and misconceptions have grown around the product, some have basis in older versions and some are just wrong. Continuing to build on the knowledge given so far these issue will be explored and broken down and proved or disproved. Finally we will look to the future and explore SQL Server 2012 and the new functionality that that brings and some of the common uses that we will be able to address. After completion of this days pre-con, attendees will have a more complete knowledge of execution plans, and how they relate to the physical and logical actions that SQLServer will be executing on their behalf. The attendees will also have a more rounded and fuller knowledge of TSQL and the implications of incorrectly defining a query. Dave is a fountain of knowledge on execution plans and optimizer internals and ,though i may flatter myself, I’m no shrinking violet when it comes to TSQL and such matters.  I hope that if you cant join us, then there are other pre-cons available from other experts in their fields that may ‘float you boat’ too.  The pre-con page is http://sqlsouthwest.co.uk/SQLSaturday_precon.htm Also, excitingly, this pre-con day is sponsored by Fusion-IO which is a great boon for the day. If you want a more of this then i am offering a 2 day TSQL course starting on the 19th of March. More details on this are available here

  • Sampling SQL server batch activity

    - by extended_events
    Recently I was troubleshooting a performance issue on an internal tracking workload and needed to collect some very low level events over a period of 3-4 hours.  During analysis of the data I found that a common pattern I was using was to find a batch with a duration that was longer than average and follow all the events it produced.  This pattern got me thinking that I was discarding a substantial amount of event data that had been collected, and that it would be great to be able to reduce the collection overhead on the server if I could still get all activity from some batches. In the past I’ve used a sampling technique based on the counter predicate to build a baseline of overall activity (see Mikes post here).  This isn’t exactly what I want though as there would certainly be events from a particular batch that wouldn’t pass the predicate.  What I need is a way to identify streams of work and select say one in ten of them to watch, and sql server provides just such a mechanism: session_id.  Session_id is a server assigned integer that is bound to a connection at login and lasts until logout.  So by combining the session_id predicate source and the divides_by_uint64 predicate comparator we can limit collection, and still get all the events in batches for investigation. CREATE EVENT SESSION session_10_percent ON SERVER ADD EVENT sqlserver.sql_statement_starting(     WHERE (package0.divides_by_uint64(sqlserver.session_id,10))), ADD EVENT sqlos.wait_info (        WHERE (package0.divides_by_uint64(sqlserver.session_id,10))), ADD EVENT sqlos.wait_info_external (        WHERE (package0.divides_by_uint64(sqlserver.session_id,10))), ADD EVENT sqlserver.sql_statement_completed(     WHERE (package0.divides_by_uint64(sqlserver.session_id,10))) ADD TARGET ring_buffer WITH (MAX_DISPATCH_LATENCY=30 SECONDS,TRACK_CAUSALITY=ON) GO   There we go; event collection is reduced while still providing enough information to find the root of the problem.  By the way the performance issue turned out to be an IO issue, and the session definition above was more than enough to show long waits on PAGEIOLATCH*.

  • Are we queueing and serializing properly?

    - by insta
    We process messages through a variety of services (one message will touch probably 9 services before it's done, each doing a specific IO-related function). Right now we have a combination of the worst-case (XML data contract serialization) and best-case (in-memory MSMQ) for performance. The nature of the message means that our serialized data ends up about 12-15 kilobytes, and we process about 4 million messages per week. Persistent messages in MSMQ were too slow for us, and as the data grows we are feeling the pressure from MSMQ's memory-mapped files. The server is at 16GB of memory usage and growing, just for queueing. Performance also suffers when the memory usage is high, as the machine starts swapping. We're already doing the MSMQ self-cleanup behavior. I feel like there's a part we're doing wrong here. I tried using RavenDB to persist the messages and just queueing an identifier, but the performance there was very slow (1000 messages per minute, at best). I'm not sure if that's a result of using the development version or what, but we definitely need a higher throughput[1]. The concept worked very well in theory but performance was not up to the task. The usage pattern has one service acting as a router, which does all reads. The other services will attach information based on their 3rd party hook, and forward back to the router. Most objects are touched 9-12 times, although about 10% are forced to loop around in this system for awhile until the 3rd parties respond appropriately. The services right now account for this and have appropriate sleeping behaviors, as we utilize the priority field of the message for this reason. So, my question, is what is an ideal stack for message passing between discrete-but-LAN'ed machines in a C#/Windows environment? I would normally start with BinaryFormatter instead of XML serialization, but that's a rabbit hole if a better way is to offload serialization to a document store. Hence, my question. [1]: The nature of our business means the sooner we process messages, the more money we make. We've empirically proven that processing a message later in the week means we are less likely to make that money. While performance of "1000 per minute" sounds plenty fast, we really need that number upwards of 10k/minute. Just because I'm giving numbers in messages per week doesn't mean we have a whole week to process those messages.

  • Munin on Centos 6 - missing perl MODULE_COMPAT_5.8.8

    - by André Bergonse
    I'm trying to install Munin on a new VPS through yum install munin but I keep getting an error about a missing perl module: Requires: perl(:MODULE_COMPAT_5.8.8). This is the perl version currently installed: v5.10.1. I've searched all around and still haven't found a solution for this.

  • ARR troubleshooting 502.3 / WinHttp tracing on Server 2012

    - by nachojammers
    I have the following scenario: 3 windows server 2012 virtual servers, all with IIS 8: 1 server with Application Request Routing 3 2 servers with the web applications that the ARR server routes to I am getting intermittent 502 3 12002 errors. Following this guide http://www.iis.net/learn/extensions/troubleshooting-application-request-routing/troubleshooting-502-errors-in-arr I have identified that I need to trace using netsh the WinHttp/WebIO providers to get to the real error code that is mapped to the 12002 error code. I run the trace as the article suggests: netsh trace start scenario=internetclient capture=yes persistent=no level=verbose tracefile=c:\temp\net.etl When analysing the output of the netsh traces, I don't get the level of information that the article suggests I should. Specifically I only get the following types of entry in the trace viewed using netmon: WINHTTP_MicrosoftWindowsWinHttp:Stopping WorkItem Thread Action... WINHTTP_MicrosoftWindowsWinHttp:Starting WorkItem Thread Action... WINHTTP_MicrosoftWindowsWinHttp:Queue Overlapped IO Thread Action... I certainly don't get anything detailed enough that would help me understand why am getting any timeouts. Is there any reason why Server 2012 wouldn't trace the WinHttp API to the level I need? Thanks

  • WmiPrvSE memory leak on Windows 2008 *R2*

    - by MichaelGG
    I've seen references on Windows 2008 to WmiPrvSE leaks, but nothing about Windows 2008 R2. We're running R2 on top of Hyper-V (2008). We are also running NSClient++ for monitoring from opsview. Over time, WmiPrvSE.exe starts to use a lot of memory, causing memory alert issues (less than 10% free). VM has 2GB, WmiPrvSE consumes up to 500-600MB before I kill it. Killing the process doesn't seem to have any negative effect; it starts up again and I haven't noticed any problems. But after a day or two, it's back in the same situation. Any ideas on what to do? Resource Monitor doesn't show any Disk or Network IO by WmiPrvSE.exe. Just slowly climbing private memory... Edited to add: We aren't running clustering, or Windows System Resource Manager. The only regular WMI user I can guess is NSClient++, but we don't seem to have this problem on other servers.

It seems to me this script downloads some remote C source codes and binaries, compile them and execute them. I am a web developer, so I am not an expert about C language, but watching at the downloaded files it seems to me a bot injected in the cron of the server. Can you give me more infos about what this code does? About its working, its purposes?

  • How to safely remove a USB device from 2008 Core server?

    - by Qwerty
    I have a Hyper-V Core server 2008 that I administer via command line and remote tools. We have now got a new backup system in place and it involves me connecting an External USB drive (G:) to backup system state files. My question is how should I safely remove the drive for its weekly offsite swap? I've tried using the devcon tool however it just says the 'removal failed with no devices removed' with no other explanation. I have noticed that there isnt a readily available x64 version of devcon and that might be the cause of the problem. (I have read of people downloading a amd64 version but I have not located it myself, if someone knows where it is please let me know). The devcon command worked on my old 2003 x86 server with the command: devcon remove *3200AVJ_EXTERNAL* I have also looked at using fsutil volume dismount g: but it doesn't seem to work as G: is still listed as a connected volume. I have checked that the volume is not in use via remote tools and the net file command. Both show no open files in the G:\ volume. This could be a decent substitute as it might be used to flush any remaining IO to the volume can anyone clarify? Thanks in advance.

  • Performance analytics via DBMS "plugins", or other solution

    - by Polynomial
    I'm working on a systems monitoring product that currently focuses on performance at the system level. We're expanding out to monitoring database systems. Right now we can fetch simple performance information from a selection of DBMS, like connection count, disk IO rates, lock wait times, etc. However, we'd really like a way to measure the execution time of every query going into a DBMS, without requiring the client to implement monitoring in their application code. Some potential solutions might be: Some sort of proxy that sits between client and server. SSL might be an issue here, plus it requires us to reverse engineer and implement the network protocol for each DBMS. Plugin for each DBMS system that automatically records performance information when a query comes in. Other problems include "anonymising" the SQL, i.e. taking something like SELECT * FROM products WHERE price > 20 AND name LIKE "%disk%" and producing SELECT * FROM products WHERE price > ? AND name LIKE "%?%", though this shouldn't be too difficult with some clever parsing and regex. We're mainly focusing on: MySQL MSSQL Oracle Redis mongodb memcached Are there any plugin-style mechanisms we can utilise for any of these? Or is there a simpler solution?

  • Coldfusion on VPS, how much JVM heap memory?

    - by Steven Filipowicz
    Recently I got a VPS server and I'm running Coldfusion, the website was running fine until it got more and more traffic and I started to encounter 'OutOfMemory' exceptions. I thought simply to rise the memory of the VPS server, but this didn't help. After doing some Google searches I found a setting in de CF Admin settings to set the JVM Heap memory. It was on the standard: Max Heap size 512MB and Min Heap size was empty. After playing around a bit I have now set it to Min 50MB and Max 200MB, good things is that I'm not getting the 'OutOfMemory' exceptions anymore. So far so good! But with about 50 active visitors on the website, the website starts to get slow. The CPU usage is only about 8% (Windows Taskmanager), also the taskmanager show only about 30% of the 3GB RAM in use. So I'm thinking that my values could be tweaked to use more of the RAM. Honestly I don't understand these JVM Memory heap settings, so I have no clue what is a good setting for me. I found a CF script that displays the memory usage, the details are: Heap Memory Usage - Committed 194 MB Heap Memory Usage - Initial 50.0 MB Heap Memory Usage - Max 194 MB Heap Memory Usage - Used 163 MB JVM - Free Memory 31.2 MB JVM - Max Memory 194 MB JVM - Total Memory 194 MB JVM - Used Memory 163 MB Memory Pool - Code Cache - Used 13.0 MB Memory Pool - PS Eden Space - Used 6.75 MB Memory Pool - PS Old Gen - Used 155 MB Memory Pool - PS Perm Gen - Used 64.2 MB Memory Pool - PS Survivor Space - Used 1.07 MB Non-Heap Memory Usage - Committed 77.4 MB Non-Heap Memory Usage - Initial 18.3 MB Non-Heap Memory Usage - Max 240 MB Non-Heap Memory Usage - Used 77.2 MB Free Allocated Memory: 30mb Total Memory Allocated: 194mb Max Memory Available to JVM: 194mb % of Free Allocated Memory: 16% % of Available Memory Allocated: 100% My JVM arguments are: -server -Dsun.io.useCanonCaches=false -XX:MaxPermSize=192m -XX:+UseParallelGC - Dcoldfusion.rootDir={application.home}/../ -Dcoldfusion.libPath={application.home}/../lib Can I give the JVM more memory? If so, what settings should I use? Thanks very much!!

  • Strange ZFS hidden filesystem problem

    - by RandomInsano
    Half of my ZFS filesystems are hidden in ZFS-fuse. Here's my story: So, I love ZFS. I used it for about six months on FreeBSD, but due to it crashing the kernel during heavy inter-filesystem IO load, I tried switching to Solaris 5.10. That was good, but when I attempted to do an import of my Version 13 pool into its Version 4 version of ZFS, there were some heafty problems. It may have tried to correct the filesystem definitions, I don't know. Since that version wasn't compatible with my pool, I've now switched to Ubuntu Server 10.4. That version more than supports that of my pool, but I can only see half of my filesystems. The filesystems I can see are the same as those Solaris could see. Now, despite those filesystems not being preset in a 'zfs list' command, I can still set properties on them and I can even still mount them and read and write files, but they just plain don't show up in 'zfs list'. I've mounted the major ones, but I'm not sure what other filesystems there are anymore (I have about eight that I can't see). Anyone have any idea what the heck is going on? I think I might try booting back into FreeBSD 8 (I still have the main boot drive laying around for that) and see if at least it is able to view the filesystems. I've also done a scrub while in Linux, and it found no errors with any of the data. Oddly, DMA read errors which caused problems on FreeBSD ZFS are reported by Linux, but ZFS-fuse doesn't find an error. That's a topic for another post however.

  • mod_perl loses STDOUT in middle of request

    - by puzzled72
    Hi, I have been having this weird issue where mod_perl seems to lose STDOUT in the middle of the request. So far I have eliminated everything I could think of. You might have seen this bug related to the following errors in error_log : Apache2 IO flush: (103) Apache2::RequestIO::read: (104) Software caused connection abort They are all the same error. It happens when the perl script running under mod_perl loses STDOUT when trying to print the result back to apache. I only notice this error on my servers running the following: (centos5.4) Perl 5.8.8-27 mod_perl 2.0.4-6 httpd 2.2.3-31 kernel-2.6.18-164.15.1 It's not the code This code has been working for months It's not network related The browser gets the error response from apache. It's not time related I get the error 15 or so seconds after I restart httpd It's not idle httpd related I have tried reducing the min/max SpareServers to 1 It's not load related I get the error even if there are only 10 sessions on httpd It's not related to the "fd < PERLIO_MAX_REFCOUNTABLE_FD" perl 5.8.8 bug I recompiled perl-5.8.8 with the patch mentioned here : https://bugzilla.redhat.com/show_bug.cgi?id=559832, same error. It appeared sometime between December 2009 and February 2010 sorry I cannot be more specific Anyone has any idea ? Anything that I have not tested ? Really Puzzled!

  • PostgreSQL lots of writes

    - by strife911
    Hi, I am using postgreSQL for a scientific application (unsupervised clustering). The python program is multi-threaded so that each thread manages its own postmaster process (one per core). Hence, their is a lot of concurrency. Each thread-process loop infinitely though two SQL queries. The first is for reading, the second is for writing. The read operation considers 500 time the amount of rows the write operation considers. Here is the output of dstat: ----total-cpu-usage---- ------memory-usage----- -dsk/total- --paging-- --io/total- usr sys idl wai hiq siq| used buff cach free| read writ| in out | read writ 4 0 32 64 0 0|3599M 63M 57G 1893M|1524k 16M| 0 0 | 98 2046 1 0 35 64 0 0|3599M 63M 57G 1892M|1204k 17M| 0 0 | 68 2062 2 0 32 66 0 0|3599M 63M 57G 1890M|1132k 17M| 0 0 | 62 2033 2 1 32 65 0 0|3599M 63M 57G 1904M|1236k 18M| 0 0 | 80 1994 2 0 31 67 0 0|3599M 63M 57G 1903M|1312k 16M| 0 0 | 70 1900 2 0 37 60 0 0|3599M 63M 57G 1899M|1116k 15M| 0 0 | 71 1594 2 1 37 60 0 0|3599M 63M 57G 1898M| 448k 17M| 0 0 | 39 2001 2 0 25 72 0 0|3599M 63M 57G 1896M|1192k 17M| 0 0 | 78 1946 1 0 40 58 0 0|3599M 63M 57G 1895M| 432k 15M| 0 0 | 38 1937 I am pretty sure I could write more often than that for I have seen it write up to 110-140M on dstat.
