Start the NDBs

Issue an NDB START command with the JOURNAL operand specified.

The first time an NDB START command (with the JOURNAL operand) is issued, it causes the journal data sets to be opened. The system normally checks both journal data sets and begins processing with the oldest one. This gives you time to run the forward recovery utility if the system was restarted after failure.

If JOURNL1 is empty, then no attempt is made to check the second data set, and journaling begins immediately on JOURNL1.
