Resource Manager Limitations
Not all resource managers support resynchronization initiated through a DCMT VARY DISTRIBUTED RESOURCE MANAGER command. This is the case for CICS resource managers and resource managers whose name ends with "DSI_SRV". Resynchronization with such resource managers can be initiated only from the associated front-end system. An error message is displayed if the specified resource manager does not support resynchronization through this command.
Deleting Resource Managers
When a resource manager is deleted, all record of that resource manager is eliminated from the system. The DCMT VARY RESOURCE MANAGER DELETE command should only be used when the resource manager no longer exists. For example, when a DC/UCF system is removed from the network. By deleting the resource manager, no further attempt is made to resynchronize with that resource manager at startup.
Note: Only resource managers whose name ends in "DSI_CLI" or "DSI_SRV"can be deleted.
For resource managers whose name ends in "DSI_SRV"
Use the DCMT DISPLAY DISTRIBUTED RESOURCE MANAGER command to determine if the resource manager has associated interests, before deleting the resource manager. If the resource manager's name ends in "DSI_SRV" the delete request fails if there are outstanding interests. Use the DCMT VARY DISTRIBUTED TRANSACTION command to manually complete each transaction before deleting the resource manager.
For resource managers whose name ends in "DSI_CLI"
If the resource manager's name ends in "DSI_CLI", its associated interests are deleted automatically as part of deleting the resource manager. After deleting the resource manager use the DCMT VARY DISTRIBUTED TRANSACTION command to complete any transactions whose interests were deleted. Since no further attempt is made to communicate with the deleted transaction managers, the transactions can now complete.
