Re: [xwiki-users] Import of XAR: Java Heap Space Out Of Memory Exception in 1.2
Hi all, I'm trying to upgrade XWiki from 1.0 to 1.2. The problem comes when I want to import my .xar file (6Mb) and get a Java Heap Space Out Of Memory Exception. I've checked your admin page http://www.xwiki.org/xwiki/bin/view/FAQ/Howtoincreasethemaximumattachmentsiz... and it looks like for my problem (file < 10Mb), only MySQL should be changed. So I've changed the max_allowed_packet parameter but the problem still occurs. I don't have anything in Tomcat or MySQL logs, which is a bit strange. The only trace I get is the one bellow. It looks like Lucene breaks because of the file upload not working. Any idea ? How could I get more details in the log ? Thanks, Antonio [http://localhost:8080/xwiki/bin/upload/XWiki/Import] [http-8080-Processor25] ERROR lucene.IndexUpdater - invalid parameters given to add: XWiki.Import, null, {grouplist={xwiki:XWiki.XWikiGuest=[], xwiki:xwiki:XWiki.XWikiGuest=[]}, fileuploadlist=[name=null, StoreLocation=D:\Servers\Tomcat\apache- tomcat-5.5.23\temp\upload_662feb76_117990b87e0__8000_00000000.tmp, size=77bytes, isFormField=true , FieldName=xredirect, name=null, StoreLocation=D:\Servers\Tomcat\apache- tomcat-5.5.23\temp\upload_662feb76_117990b87e0__8000_00000001.tmp, size=20bytes, isFormField=true, FieldName=filename, name= Backup2008-01-20.xar , StoreLocation=D:\Servers\Tomcat\apache- tomcat-5.5.23\temp\upl oad_662feb76_117990b87e0__8000_00000002.tmp, size=6639095bytes, isFormField=false, FieldName=filepath], msg=com.xpn.xwiki.web.XWikiMessageTo ol@1171e30, util=com.xpn.xwiki.util.Util@bf1a4a, baseskin=albatross, tdoc= XWiki.Import, ajax=false, locale=fr, doc=XWiki.Import, mainxwiki=x wiki, skin=albatross, message=javaheapspace, fileuploadplugin=com.xpn.xwiki.plugin.fileupload.FileUploadPlugin@571cc4, vcontext=org.apache.v elocity.VelocityContext@1219665}

There are 2 places where to make changes when you want to import a large XAR: 1) the mysql config as you said, 2) the XWikiPreferences object. Before 1.2 it had a max of 1MB if I recall correctly. In 1.2 we've upgraded it to 30MB I believe. However if you're using your old XWikiPreferences object then you'll have th max_upload_size set to the old value. See http://jira.xwiki.org/jira/browse/XE-145 Now regarding lucene I don't understand why this the import has anything to do with lucene but there's probably something I don't know here... Try changing the max file upload parameter in your xwikipreferences and try the upload again. -Vincent

Hi everybody, I'm bringing this issue back but it still doesn't work. This is what I'm doing : I'm starting everything from scratch : new database completly empty and a fresh XWiki 1.2.2.7518 on a fresh Tomcat 5.5.26 and a 5.0.41 MySQL (with a 5.1.5 driver). Just after installing XWiki, I try to import my 6Mb xar file that I've exported from a XWiki 1.0. I select my file, click on Upload and I end up with a "Java Heap Space Out Of Memory Exception" without any stack trace. Notice that it breaks even before showing the page allowing me to select the file. Here is how I've checked that MySQL could handle 6Mb : SHOW SESSION VARIABLES like max_allowed_packet'; and SHOW GLOBAL VARIABLES like 'max_allowed_packet'; Both results are 16Mb (max_allowed_packet = 16776192). I don't know how to get the value max_upload_size from XWiki.Preferences but following what Vincent said and http://jira.xwiki.org/jira/browse/XE-145 it should be set to 32Mb. In terms of size (MySQL and XWiki) it looks like it can handle 6Mb. I have several archives. So I've tried with a 2.2Mb xar file. It also breaks but the behaviour is different. After clicking on upload, XWiki shows me the page allowing me to choose from a file (this page doesn't even appear with the 6Mb file). But then it breaks with a more explicit stack trace (as follow).

You definitely can't do that. The default configuration for HSQL is to use in-memory tables. All that data can't fit in the memory you've configured. You'd have to switch to a different database.
and i can't find max_upload_size in XWiki preferences
thanks for helping me i'm really stucked on this one
Hi, aie,aie,.. that's a real bad news for me, because i was counting on that but is there a solution to change the configuration of hsql, to put tables in files for example directly on disk not on memory or to extend the size of the memory allowed to him ( i can get a 4Go of RAM for my PC) or if i have to switch to another database is there a solution to migrate my hsql database with its contents to the new database mysql. thanks so much for helping me it's so important for the job thank you -- View this message in context: http://n2.nabble.com/Re-Import-of-XAR-Java-Heap-Space-Out-Of-Memory-Exceptio...

Hi guys, We are experiencing serious performance problems with the Blog application. We cloned it in version 2.1 and did a few minor mods. We have under 1000 blog entires now in about 60 categories, some are subcategories. Loading the category management page takes about a minute. I have seen no big database activity, there is mostly a load on the cpu of the application server. Does anyone know how to fix this? For example when looking at the add a post page, the same tree is displayed there, but loading is much faster. I was trying to load the tree in a simple way and add the add category functionality, but it rather a PITA. We have multiple people using the Blog at the same time, does anyone know a fix? Kind regards, Vincent Gerris
