I have a scenario to migrate the Oracle application along with memory from one vPar to another. If I migrate the Oracle DB from one vPar to another, the memory should be moved along with. The memory is a floating memory.
But When I migrate the oracle package using SG, the primary node takes a while (>20 seconds) to release its memory. So the package got started on the adoptive node without Memory migration.
But the same case works vice-versa. So it seems there is a performance issue with the primary node, which takes a long time to release the memory with vparstatus command. The user defined command to delete the memory is "vparmodify -p
Is there anything to fasten the vparmodify command activity.
Thanks,

Re: vparmodify command delay
Run ioscan -fnC fc and then check the HW attached to the HBAs using ioscan -fnH
If insf -eC disk is not able to create device new files ,most likely it`s a SAN issue.
Post the above output.
Thanks

to get more information.
The system needs some time to free up the memory.
Hope this helps!

Re: vparmodify command delay
Thank you for the suggestion. The same case works fine when migrating the package from the adoptive node to the primary node.
As per the document, the vpar will take some time to release the floating memory. But both the vpars were identical here.
Is there any kernel level parameters there to configure them?
Thanks,
Jayaprakash S
