Memory Allocation Pool

[Brad Huddleston]

So after upgrading and configuring, I'm not getting these messages when starting JIRA:

Setup: Your memory allocation pool settings need attention

JIRA runs in a Java virtual machine (JVM), and this JVM is allocated an amount of memory to enable JIRA to run. These amounts can be manually configured.

• The maximum memory allocation pool (-Xmx) is required to be at least 786m.

Setup: Your memory allocation pool settings need attention

JIRA runs in a Java virtual machine (JVM), and this JVM is allocated an amount of memory to enable JIRA to run. These amounts can be manually configured.

• The initial memory allocation pool (-Xms) is recommended to be at least 384m.

I have adjusted the JVM_MINIMUM_MEMORY and JVM_MAXIMUM_MEMORY variables in the setenv.bat file but nothing works.

I got to this point after this issue: JIRA-Will-Not-Start-After-Upgrade

Hi Brad,

The steps needed to increase the memory for Jira on windows systems can be different depending on how you start Jira: starting Jira via .bat files vs starting Jira via a Service. 

Details of this are in Increasing Jira memory.   Hence if you're trying to start Jira via a service, the changes you make to the setenv.bat file won't actually be honored when Jira starts.  Instead there are different steps needed to configure this listed in that document.

I would recommend setting the -Xmx and the -Xms values to be the same.  It can help prevent the JVM from doing pauses in order to resize the heap.

Check that out and let me know if this helps.
