vmcj/sgc_options is a SAP Parameter attribute which is used to control Configure VMC options for the shared Garbage Collection information. This is available within R/3 SAP systems depending on the version and release level.
Below is the standard documentation available and a few details of the attributes values .
You can use this parameter to control the behavior of the Virtual
Machine Containers (VMC) while a shared garbage collection (SGC) is
being configured. The following options are possible:
TEMPLATE_CLEANUP This sets that the template VM performs a garbage
collection before a new VM is created The advantage of this is that the
created VM contains no rubbish.
DELAY_SESSION_CLEANUP This option delays the deletion of Java sessions
for a SGC. This helps in reducing the workload during an SGC.
Syntax
vmcj/sgc_options = [TEMPLATE_CLEANUP] [,] [DELAY_SESSION_CLEANUP]
Examples
vmcj/sgc_options = TEMPLATE_CLEANUP
vmcj/sgc_options = TEMPLATE_CLEANUP, DELAY_SESSION_CLEANUP
Caution
The default setting of these options is inactive. Since the achieved
effects strongly depend on the individual configuration of the VMC,
these options should only be used after consulting SAP.
