Zero Downtime Backup of MaxDB database with HP Data Protector

Appendix B
The following is a complete Data Protector session report which shows what happens if you start
MaxDB data volume ZDB backup session when the MaxDB logwriter process has already been
suspended. The backup successfully completes, and the script reports an error, displayed in the Data
Protector session report, stating that the MaxDB log suspend command cannot be executed again on
a MaxDB instance where the process is already in suspension.
However, since the prerequisite for splitting is satisfied in that the MaxDB logwriter process is indeed
suspended, Data Protector continues to split the replica, after which it resumes the MaxDB logwriter
process. Subsequently the backup is streamed to tape. Compare this against the impact of resuming
the MaxDB logwriter process on an already working logwriter process (see Appendix C
on page 45).
