4.3.3.3.6 RESTORE Job Steps
The actions being performed within each step of the RESTORE
job are discussed below.
If you specified RESTORE BACKUP YES in
prefix.MICS.PARMS(JCLDEF), the RESTORE job begins by
executing a Database backup as described below.
Step BKUP900: Database backup.
1. Verify that prerequisite step completed successfully.
2. Update the Checkpoint File -- BKUP900 in progress.
3. Backup the Checkpoint File
4. Copy online database files to timespan backup data
sets.
Step BKTLIB: Backup sharedprefix.MICS.ISPTLIB (PRIMARY unit
database only).
1. Copy sharedprefix.MICS.ISPTLIB to the ISPTLIB backup
file.
Step BKUPRSR: Run Status Report.
1. Generate CA MICS Run Status Report
Step IDCAMS: Produce CA MICS Catalog List.
1. Generate Catalog List for all 'prefix.MICS' entries.
RESTORE processing follows the backup. The RESTORE steps are
described below.
If you specified RESTORE BACKUP NO in prefix.MICS.PARMS
member JCLDEF, the RESTORE job only executes the following
steps.
Step RSTR900: Database Restore.
1. Print current Checkpoint File contents.
2. Update the Checkpoint File -- RSTR900 in progress.
3. Print the backup Database Checkpoint File.
4. Perform Checkpoint File restore.
5. Update the restored Checkpoint File -- RSTR900 is still
in progress.
6. Perform PROC DATASETS KILL on each timespan to delete
the existing online database files.
7. Copy timespan backup data sets to online Database
files. Uncompressed files are restored, and if you
have compressed files, they are restored in a second
pass of the tape.
8. If incremental update is active for any product in the
unit database, examine the product's incremental update
checkpoint file and issue messages warning that running
IUDBINIT may be required to re-initialize in-progress
or completed incremental update processing prior to
resuming database update processing.
9. Update Operational Status and Tracking control tables.
a. Store RESTORE job status.
b. Update the operational job log.
10. Update the Checkpoint File--RSTR900 completed.
Step RSTRRSR: Run Status Report.
1. Generate CA MICS Run Status Report.
2. Update Operational Status and Tracking control tables.
a. Store RESTORE job status and update status for all
operational jobs.
b. Update the processing schedule for the next 7 days.
c. Update the operational job log.
