Confluence Increase Maximum Heap Size

You can only view Maximum Heap Size  from Confluence > Administration > System Information.

To Edit:

Do not set your memory using CATALINA_OPTS this is overridden by JAVA_OPTS.
On Linux

• In the unpacked Confluence standalone directory, edit the file bin/setenv.sh
• Edit the line beginning with JAVA_OPTS= substituting new values for -Xms (starting memory) and -Xmx (maximum memory)
• Leave the rest of the options in that line unchanged

An example of a minimal setting for a large system - max heap size is set to 1Gb :

JAVA_OPTS="-Xmx1024m $JAVA_OPTS -Djava.awt.headless=true "

The SystemInformationService could not be retrieved from the container. Therefore very limited information is available in this error report.
The SystemInformationService could not be retrieved due to the following error: java.lang.NullPointerException
Cause
com.atlassian.util.concurrent.LazyReference$InitializationException: java.lang.NullPointerException
at com.atlassian.util.concurrent.LazyReference.getInterruptibly(LazyReference.java:152)
caused by: java.lang.NullPointerException
at com.atlassian.spring.container.ContainerManager.getComponent(ContainerManager.java:33)

If you get this error message, permission error may cause this error.
To solve it,
1. Go to your confluence home directory
2. list all items with ls -al

testwww1:/usr/local/confluence-data# ls -al

total 152

drwx--S---  19 confluence confluence  4096 2012-08-20 10:27

(...)

drwxr-sr-x   2 root       confluence  4096 2012-07-10 15:41 plugins-cache




3. Then, (Our) Confluence is running with confluence user, so permissions were wrong (without writing for group). When I changed owner with:

chown -R confluence:confluence confluence chown -R confluence:confluence confluence-data

 and restarted Confluence with

/etc/init.d/confluence restart

 it raised up and is working. Hope you will find it useful :)

2. Copy the generated code.
3. Create a confluence page or open editing for an existing one. Add a html-include macro.
4. Paste the copied code into it, and save the page.
