changing 32BIT O.S to 64bit in JIRA server

Question

Hi Team,

We are frequently facing OOM error in JIRA due to this our JIRA application is going down. Increasing memory from 2GB to 3GB will help to over come the issue. While trying to increase we faced error.

Since JIRA is running by 32 bit java, we are not able to increase its memory more than 2 GB.

JIRA will run on both 32 bit and 64 bit JVM without any compatibility issue. So that we tried change to 64 bit java on JIRA server. We encountered an issue while upgrading java from 32 bit to 64 bit.JIRA server is running on a 32 bit OS. Refer below,

FYI : JIRA version is 6.4.

So now we are stuck. Could you please advise how to convert 32bit O.S to 64 bit so that we can upgrade the jira then Java then increase memory.

To upgrade JIRA server from 32 bit to 64 bit, also require JIRA applications (eg. JIRA Software,  Service Desk, App-ons etc)  to upgrade to 64 bit version ?

Referred many sites bit could not find proper way.Please help advise.

Thanks,

Pavithra

You won't be able to install a 64bit Java to a 32bit operating system.   It just is not possible for the OS to run that environment.   But I agree with @Nic Brough -Adaptavist-, that the solution here is to backup your Jira data, and then install Jira to a new 64bit operating system, and restore your data there.

In theory you might be able to upgrade an existing OS, but I have never had success with this approach, and in my experience it tends to require to you reinstall Jira anyways, so I find it to be better to just do that on a new machine.  It is preferable to simply install Jira to a new server that already has a 64bit OS, and a 64bit version of Java.  When you look at the Jira Archives, you will notice that for Jira 6.4.x versions there exists both a 32bit and 64 bit installation packages for both Linux and Windows.  I would recommend installing a Linux 64bit installer to a new Linux 64 bit operating system.

There are two routes, but they are similar.

Backup Jira to XML, or get a database dump and a copy of the attachments.

* Install the new operating system
* Install a clean empty Jira on it, get it working, then stop it.
* Restore the xml or the database
