Using CICS® DA, you
can install CICSPlex® SM
definitions in an unmanaged CICS region
and add the region to an existing CICSplex. Optionally, you can also
add the region to one or more of the system groups in the CICSplex.
Before you begin
Ensure that the CICS region
you want to add is in the model and that the region start policy is
recorded. For more information about recording the start policy, see Specifying the region start policy.
Procedure
- In the DA Explorer view, double-click the unmanaged CICS region to add to a CICSplex,
or right-click the region and click Open. The CICS region
editor opens showing the details of the selected region.
- In the CICSPlex System
Management section, click Add to CICSplex. The Add CICS Region to CICSplex window
opens: The window lists the CICSplexes in the system model. When
you select a CICSplex, the CMASes and Groups in that CICSplex are
shown.
- Select the CICSplex and the CMAS to which you want to add
the CICS region. Optionally,
select one or more groups to which to add the region.
- Optional: If the region is started as a batch
job, create new JCL for the job by clearing the Replace
existing JCL check box. Type the name of the new JCL in
the field. Alternatively, enter one or more of the qualifiers and
click Browse to find the data set.
- If your JCL contains any INCLUDE or SYSIN statements, CICS
DA cannot always be sure whether the INCLUDE and SYSIN members are
used by other regions. By default, CICS DA creates new members, and
changes the INCLUDE and SYSIN statements to reference the new members.
You can clear the Create new members for INCLUDEs and SYSIN if
required if you want to change and use the existing INCLUDE
or SYSIN members.
- Click Finish to start the process
of adding the CICS region to the CICSplex.
Results
When you click Finish, CICSPlex SM definitions are added to the
JCL that starts the region and a report is shown in the Console view.
What to do next
You must restart the region for the changes to take effect.
In addition, if the region is a version 3.1 region you must upgrade
the system definition data set (CSD).
The console report shows
details of the changes that are made to the JCL. The report also identifies
some other tasks that you might consider carrying out for the new
managed region, such as reviewing some SIT parameters and setting
up monitoring.
