Deleting structures z/OS MVS Setting Up a Sysplex SA23-1399-00 |

Deleting an active structure for CF reconfiguration or maintenance should only be considered when the structure cannot be relocated to an alternate CF. For example, although IBM® does not recommend relying on a single CF in the Parallel Sysplex®, a configuration with a single CF provides no alternate CF into which structures can be rebuilt. The procedures in the following sections describe how to delete active IBM software structures. For structures not listed, similar information should be provided in the application documentation. Verify the deletion of the active structure instances with the DISPLAY XCF,STRUCTURE,STRNAME=strname system command. If a structure dump exists for the structure, consider making a dump data set available to capture the dump. If an SVC dump is not in progress, deletion of the structure dump can be forced in order to allow the structure to be deallocated with the SETXCF FORCE,STRDUMP,STRNAME=strname,STRDUMPID=strdumpid system command. If a structure is pending deletion or in transition, restore connectivity to the CF. If connectivity cannot be restored to the CF, the structure can only be removed by deleting the CF from the CFRM active policy. See Removing a coupling facility from the configuration. |
