Managing Shared Closures 

Use

Shared Closures are Java objects that are located in the shared memory and can be used by several VMs. You can display and manage all the shared closures in the VMC system administration.

You can also implement a garbage collection for the shared closures.

Procedure

On the initial screen of the VMC system administration (SM53) in the structure on the left side under Navigation double-click on Shared Closures.

In the area on the right you will see the hierarchical structure of the existing shared closures.

For each shared closure the following information is shown:

●     Size in bytes (depending on the hierarchy level in the tree, includes all lower-level nodes)

●     Currently existing versions (identifiable from the number of memory blocks and from the number in the Version column).

You can delete shared closures by selecting the small box and choosing  (Delete Memory Areas) in the title line.

You can delete shared closures only if you have the authorization to do so in your user profile. In field ACTVT of authorization object S_VMCADMIN you must have values 02 (change) and 06 (delete). These authorizations are in the standard profile S_VMCADMIN_1.

The operation of the VM Container may be disrupted when shared closures are deleted. Therefore you should only delete shared closures after consulting with SAP.

The  icon next to a memory area in the Deletion Indicator column means that the corresponding memory block is flagged for deletion. There is a newer version of the shared closure that you can see selected on this screen under vmc/appmgmt/act_groups/ ActGrp_1.
