Completing the Rebuild Connect Phase

z/OS MVS Programming: Sysplex Services Guide
SA23-1400-00

When connected users have performed the necessary processing to propagate (or reconstruct) data into the new structure, they must:

  1. Complete all outstanding requests to the structure
  2. Prevent new structure requests like IXLCACHE, IXLLIST, IXLLOCK, or IXLRT
  3. Issue IXLREBLD REQUEST=COMPLETE.

If this is a structure rebuild, as each connector issues IXLREBLD REQUEST=COMPLETE, the system invalidates both the temporary and the original connect tokens to prevent access to either structure. The reason you are not allowed access to both the old and the new structure between the time you issue the IXLREBLD REQUEST=COMPLETE and the time you receive the Rebuild Process Complete event is because there is still the possibility of the rebuild processing being stopped. If that occurs, the new structure would be deallocated and normal processing would continue using the old structure. When the system has received IXLREBLD REQUEST=COMPLETE from all connectors, the Rebuild Complete sync point is reached and processing continues with the Rebuild Cleanup phase. See Completing the User-Managed Rebuild Process.

If this is a duplexing rebuild, when the system has received IXLREBLD REQUEST=COMPLETE from all connectors, the Rebuild Duplex Established sync point is reached and processing continues with the Duplex Established phase.
