Hi Subramanian,

Just want to inform you that it is not recommended for you to rely on XML backup and restore method as the sole backup solution of your production instance, since this method is meant only for evaluation purposes and other than the fact that it require a huge resources to finsihed it is also not reliable for huge instances (data lost due to corruption).

We highly recommend you to review our documentation regarding our production instance backup strategy. Hope it helps.

Cheers,

Hi Saravanan,

From the stacktrace it seems that it's out of memory issue. Please refer to this document for more information.

Hi Rian,

Thanks for your reply. Currently i have the below in setenv.sh

JAVA_OPTS="-Xms1769m -Xmx1769m -XX:MaxPermSize=512m $JAVA_OPTS -Djava.awt.headless=true "

could you please advise how much need to increase ?

Thanks,

Saravanan

[Nic Brough -Adaptavist-]

Add 128 to the MaxPermSize and try it again. You may need to go yet higher though

[saravanan subramanian]

Hi Nic,

Do i need to restart the server after adding the 128 to MaxPermSize ?

[Septa Cahyadiputra]

Yes restarting the instance is necessary for the changes to be applied.
