Selecting the recovery point
The first step in building the coordinated recovery jobs is to select a consistent point in time for both the Db2® objects and the IMS databases that can be used as the recovery point.
Procedure
- Specify 2 (Application Operations) on the IMS Recovery Expert main menu panel (BSY$MAIN) and press Enter.
- Specify 2 (Coordinated Application Profiles) on the Application Operations Menu panel (BSY$APMN) and press Enter.
- On the Enter Coordinated Recovery Profile Selection Criteria panel, specify your filter criteria and press Enter. For more information about the options on this panel, see Managing the coordinated recovery process.
- On the Coordinated Recovery Profile Display panel,
specify B on the Cmd line
next to the coordinated recovery profile for which you want to build
the recovery jobs.

- On the Recovery Point Selection panel,
select a recovery timestamp by specifying S next
to one of the following recovery point types:
- Select Current to specify that recovery will be to the current point in time, or the time when the recovery jobs run. A confirmation panel opens. When a coordinated recovery to current is performed, the Db2 and IMS recovery jobs are generated, and the job step to start the Db2 and IMS databases after performing recovery is commented out. After completion of the Db2 and IMS recoveries, you will edit the JCL to remove the comments from the steps to start the Db2 and IMS databases, and resubmit the job to start the databases. Do not start the recovered databases until both recovery jobs complete successfully, to ensure that all of the Db2 objects and IMS databases are consistent. Specify Y in the Confirm field to indicate that you understand the message and you want to proceed with the build process. Specify N to return to the Select Recovery Point panel to choose another type of recovery point.
- Select User Timestamp to specify a timestamp for the recovery. Press Enter. The Select Recovery Timestamp panel opens. Specify the timestamp to which you want to recover. The format of the timestamp that you specify is YYYY - MM - DD - HH : MM : SS : MMMMMM.
- Quiet Time range: If you ran a log analysis for the coordinated recovery profile and any quiet times were identified, these ranges are available for selection. Each quiet time range that was discovered is displayed as a start timestamp YYYY-MM-DD-HH:MM:SS:MMMMMM and an end timestamp in the same format. If you did not run log analysis, no quiet time ranges are displayed.
- Press Enter. The Generate Db2 Recovery Plans panel opens.
