Usage notes for RECOVER CFSTRUCT

 

Notes on using RECOVER CFSTRUCT.

• The command fails if the application structure is not flagged as being in a FAILED state.

• The command fails if any one of the specified structure names is not defined in the CFRM policy data set.

• The recover process is both I/O and CPU intensive, and can only run on a single z/OS image. It should therefore be run on the most powerful or least busy system in the queue-sharing group.

• The most likely failure is the loss of a complete CF and hence the simultaneous loss of all the application structures therein. If backup date and times are similar for each failed application structure, it is more efficient to recover them in a single RECOVER CFSTRUCT command.

• This command fails if any of the specified CF structures is defined with either a CFLEVEL of less than 3, or with RECOVER set to NO.

• To use TYPE(NORMAL), have taken a backup of the CF structures, using the BACKUP CFSTRUCT command.

• If backups of the requested CF structures have not been taken recently, using TYPE(NORMAL) may take a considerable amount of time.

• If a backup of the CF structure, or a required archive log, is not available, we can recover to an empty CF structure using TYPE(PURGE).
