How z/OS rebuilds a resource structure

Resource structures are defined with system-managed rebuild, so z/OS® automatically rebuilds the structure when no CQS is up to build the structure. z/OS cannot rebuild the structure if the structure fails or if z/OS loses connectivity to the structure.

If any CQS is up and rebuild is initiated with the SETXCF START,REBUILD command, then CQS copies the structure. If the structure fails, no structure recovery is initiated because resource structures do not support structure checkpoint.
