When you use the Recovery Point ID (RPID) ISPF interface to generate IMS Database Recovery Facility jobs, you must specify the database components
that you want to recover and the recovery time.
Using the RPID ISPF interface with the RPID report allows you to specify database components and
recovery times directly from the RPID report.
Because the RPID report lists validated recovery time spans
for one or more databases, you do not have to independently verify
database components and recovery times.
Before you begin, complete
the following prerequisite tasks:
Install the Extended Functions ISPF
interface and allocate the ISPF libraries required for the RPID ISPF
interface.
Run the RPID function to generate an RPID report.
The report must be in an EDIT or VIEW
session.
To recover a group of database components to a common recovery point, make sure that a common
time span exists for all of the database components.
If the database components do not have a
common time span, you can generate one by using the Recovery Point Create function.
To select the database components and recovery times
by using the RPID ISPF interface with the RPID report:
Start the RPID ISPF interface with the RPID report by issuing
the IROTREXL command on the command line of an RPID report:
Command ===> irotrexl
After
you start the RPID ISPF interface, the initial RPID ISPF interface
panel is displayed, as shown in the following figure:

The RPID ISPF interface contains help panels that provide more detailed information about the
interface and its options.
You can access help panels by pressing the PF1 key at any time.
Select Common Time Span processing.
In the Common Time Spans panel, select a common time span
to limit the recovery to a specific time span.
A common time span helps you recover a group of database components to a common recovery point.
If you do not select a common time span, generated control statements will not contain an RCVTIME
parameter, and any subsequent option that relies on a common time span cannot be selected.
For examples, the following figure shows that the 21.338 11:10:19.946777+0000 -- 21.364
14:15:40.100000+0000 common time span was selected after S was entered to the
left of the selection.
The selection is now indicated by *Recvr.

Exit the Common Time Spans panel and select Database
component processing from the IMS Recovery
Point ID Report panel.
In the Database Component Processing panel, enter a forward
slash (/) to the left of the components that
you want to recover.
A list of processing options is displayed that allows you to specify the recovery options for the
selected component.
For example, you can specify the time to which components are to be recovered, exclude specific
components for recovery, or view more information about each component.
Attention: To
avoid data integrity exposure, do not specify individual ddnames for
recovery. If you want to specify individual ddnames, make sure that
you are familiar with ddname recovery and its implications.
The
following figure shows that the partitions POHIDKB and POHIDKC are
selected for recovery and that the full recovery time of ddname POHIDKCB
is selected as the recovery time. All other components are excluded
from recovery.

When you select a recovery time, the database component that you selected the recovery time from
is highlighted. Any parents and children of that database component are also
highlighted.
If you have specified a recovery time, the time is shown in the Recovery
basis field.
The Recover column contains recovery status indicators that define how JCL will be generated for
each component.
After you have selected the components that you want to
recover, exit the Database Component Processing panel.
Optional: To review a summary of your recovery
selections, select View selected recovery basis from
the IMS Recovery Point ID Report
panel.
Select Generate IMS Database Recovery Facility
JCL to complete the selection of database components and
recovery times.
The IMS Database Recovery Facility Job Generation panel is
displayed, which allows you to customize parameters, customize control statements, and add
additional JCL before generating the IMS Database Recovery
Facility job.
