Data restore of an entire system

The RESTORE SYSTEM utility invokes z/OS® DFSMShsm services to recover a Db2 subsystem to a prior point in time.

The RESTORE SYSTEM utility restores the databases in the volume copies that the BACKUP SYSTEM utility provided. After restoring the data, the RESTORE SYSTEM utility can then recover a Db2 subsystem to a given point in time.

The SYSPITR option of DSNJU003 CRESTART allows you to create a conditional restart control record (CRCR) to truncate logs for system point-in-time recovery in preparation for running the RESTORE SYSTEM utility.

The SYSPITRT option of DSNJU003 CRESTART allows you to add a timestamp, in the ENDTIME format, to truncate logs for system point-in-time recovery restart.

You can specify a value of 'FFFFFFFFFFFF' to cause system point-in-time recovery to occur without log truncation.
