JVM memory settings

[Eladó Lakás]

Hi,
I would like to setup less maximum memory than JVM_MAXIMUM_MEMORY="768m".

If I start with new settings error message comes and tells I can't setup less than 768m.
With older Jira I didn't have this Problem.
How can I ignore this error?

You can't.

The memory check has been coded into Jira because it really does need it.  Even if you do manage to bypass it and drop it to 512m, you'll find Jira rarely gets through the start up process without timing out or running out of memory (and there's no chance if you've got JSD or Software or any of the bigger Apps added).  On the rare times it does get through startup, it's so slow it is useless to even a single user.

You need to run Jira with at least 700m RAM allocated, or you simply won't have a usable system.

thanks your reply.

I understood it has its's needs, but
Total Memory 742 MB Free Memory 358 MB Used Memory 384 MB

So there would be some tweeking place.
I would use it for home tracjing system, so if page loading takes 5sec it wouldn't be a big problem.

It needs all of that 768M intermittently.  The most obvious time is during start-up, but it's going to need it again during normal execution.  

It doesn't matter what memory it is using now, it matters when it peaks, which it will do.  With too little memory, it's always going to be painfully slow, but it's going to crash a lot as well.

You really do need to give it the full 768m it is asking for.
