Conditional restart with system-level backups

You can recover a Db2 subsystem to a point in time (system point-in-time recovery) where the log copy pool is restored from a system-level backup. In this case, perform a conditional restart with a log truncation point that is less than or equal to the data complete log record sequence number (LRSN) of the system-level backup.

For example, create the conditional restart record by using the data complete LRSN as the CRESTART ENDRBA, ENDLRSN, or SYSPITR log truncation point for the change log inventory utility, DSNJU003. The data complete LRSN is externalized in the DSNU1614I message that is issued by the BACKUP SYSTEM utility when a system-level backup completes.

You can use the print log map utility, DSNJU004, to print the information for a system-level backup. This information includes the data complete LRSN. Using the DSNJU004 utility is beneficial if you did not preserve the job output or the log that contains the DSNU1614I message.
