Db2 restart
A key to the perception of high availability is getting the Db2 subsystem restarted quickly after an unplanned outage.
- Some restart processing can occur concurrently with new work. Also, you can choose to postpone some processing.
- During a restart, Db2 applies data changes from its log that was not written at the time of failure. Some of this process can be run in parallel.
- You can register Db2 to z/OS Automatic Recovery Manager (ARM). This facility automatically restarts Db2 should it go down as a result of a failure.
