Hi All I have problem to configure xwiki7 To attach big file to wiki The steps that I did are: Size Limit The maximum size of an attachment is limited by a configuration parameter in the XWikiPreferences document. It is set to about 32MB by default. To change it follow these steps: 1. Go to http://<yourwiki>/xwiki/bin/edit/XWiki/XWikiPreferences?editor=object<http://%3cyourwiki%3e/xwiki/bin/edit/XWiki/XWikiPreferences?editor=object> 2. Click on the line that says XWikiPreferences 0 (right below the line that says Objects of type XWiki.XWikiPreferences (1)) 1. Scroll down to the field that says Maximum Upload Size and change the number to 10737418240 bytes which is 10GB 2. Scroll to the bottom and click "Save" 3. Restarted the tomcat 8 This didn't work: I am getting message that I can't attach files larger then 32mb 1. I have tried to attach a video file that about 32mb I got those messages: [Caused by: java.lang.OutOfMemoryError: Java heap space among the long message] A problem occurred while trying to process your request. Please contact the webmaster if this happens again.

I have change the attachment location to: a. To change the storage location do: [root@ cat /usr/apache-tomcat-8.0.20/webapps/xwiki-enterprise-web-7.0/WEB-INF/xwiki.properties |grep -n environment.permanentDirectory 78:# environment.permanentDirectory=/var/local/xwiki/ b. I will change it to : environment.permanentDirectory=/usr/apache-tomcat-8.0.20/Attachments a. c. My vim setenv.sh JAVA_OPTS="${JAVA_OPTS} -Djava.awt.headless=true" CATALINA_OPTS="-server -Xms800m -Xmx800m -XX:MaxPermSize=196m -Dfile.encoding=utf-8 -Djava.awt.headless=true -XX:+UseParallelGC -XX:MaxGCPauseMillis=100" export JAVA_OPTS CATALINA_OPTS Please advise how to change the configuration to be able to attach big files to wikis Thanks _______________________________________________ users mailing list users(a)xwiki.org http://lists.xwiki.org/mailman/listinfo/users

It seems that now, you should be able to increase the file size limit in XWiki preferences (upper to 32M). This configuration parameter is still used in the wiki. To be more precise, without file storage attachment disabled, attachments are directly loaded into the RAM of the JVM... and this is what make it explode most of the time. With file storage attachment enabled, the attachment is not loaded in the RAM of the JVM and then, you don't have the problem anymore. However, and these are the tricky points. It seems that even with file storage attachment enabled, you will still reach the problem of RAM in JVM if you try to export a page in XAR (because the JVM will need to load the attachment in RAM to generate the export). Moreover, it will be the same for deleting the wiki page (since system use export functionality to move it to the recycle bin). But for the deletion, there is a workaround: you can delete all the attachments before deleting the page. If you finally decide to restore the page, you can restore it (which will restore the last version, therefore without attachment) and then rollback the history to get back the attachments.

Hope this helps.
