Shared memory concept in Java Stack

[Former Member]

Hi,

While restarting the Java stack we have been advised to give the command :

jcontrol -c <hostname> to clear the shared memory. Though i am using it for restarting i am not clear about the concept of

shared memory and the need to clear it for restarting. Can any please provide the documentation about the shared memory of

java and its monitoring.

We have been searching help.sap.com and couldn't find the required documentation.

Kindly advise me in this regard,

Thanks & Regards,

Hi rama krishna,

For SAP Java stack, SAP JVM hadles/manages the shared memory. One should know how much memory to allotted for maximum and minimum spaces and how this memory being managed using the concept of Garbage Collector tool.

Please refer to below link that describes full in details about SAP JVM
