Connecting CICS to Db2 (optional)
Connecting CICS® to Db2 is an optional part of migrating members in a data sharing group. Connecting Db2 to CICS requires that you regenerate several CICS tables with additional entries.
About this task
A macro is supplied with CICS to define the connection between CICS and Db2 by using a resource control table (RCT).
Ensure that you coordinate the attachment facility connection with your CICS support group.
Procedure
To connect the CICS attachment facility:
- Recalculate space requirements for the CICS attachment facility.
- Define your CICS attachment facility parameters using the RCT.
- Update the CICS system tables.
- Update the CICS initialization JCL.
- Coordinate Db2 and CICS security if necessary.
- Prepare new CICS applications for Db2 if necessary.
