User-Managed Rebuild Timeline summarizes the phases associated with the user-managed structure rebuild process.

The following list summarizes that process:

1. Rebuild for a structure is initiated through SETXCF START,REBUILD or IXLREBLD REQUEST=START or internally by MVS™.
2. System reports Rebuild Quiesce event to each connector's event exit.
3. Connector stops activity to original structure and issues IXLEERSP EVENT=REBLDQUIESCE to respond to the event.
4. When all IXLEERSP responses are received, the system reports Rebuild Connect event to each connector's event exit.
5. Connector issues IXLCONN REBUILD for the structure. If the first to issue IXLCONN, the connector allocates the new structure; otherwise, the connector connects to the new structure.
6. At any time after successfully connecting to the new structure, the connector issues IXLCACHE, IXLLIST, IXLLOCK, IXLRT and other coupling facility macros to rebuild data for the structure.
7. When all connectors issue IXLCONN REBUILD, the system reports the Rebuild Connects Complete event to the connectors' event exits.
8. When the rebuild is complete, each connector issues IXLREBLD REQUEST=COMPLETE.
9. When all connectors have issued IXLREBLD REQUEST=COMPLETE, the system reports Rebuild Cleanup event to event exit.
10. Each connector cleans up references to original structure and issues IXLEERSP EVENT=REBLDCLEANUP.
11. When all IXLEERSP responses are received, the system reports the Rebuild Process Complete event to event exits.
12. Connector resumes normal processing with the new structure.
