CICS IA supports DB2 Version 7 and above. If you are planning to install CICS IA with DB2 Version 8 in compatibility mode when you use the supplied configuration exec select V710 as your DB2 version.
On any region, on which you intend to collect DB2 data, ensure that the user ID, under which the CINB transaction runs, has permission to access the SYSIBM.SYSPACKSTMT and SYSIBM.SYSSTMT DB2 tables. You can get this access by giving the userid access to the CICS IA plan for the CINB transaction. See section Granting access to the plans and tables.
The user ID under which the CINB transaction runs is dependent on how CICS IA is activated using CINT. In most cases the "CICS default User Id" is used. However, there are cases where it might be the PLT user ID if started by PLT processing, the ID of the current CINT transaction, or the "Link ID" if the CINT transaction is routed to another CICS region.
The batch jobs to load all CICS IA database use the DB2 LOAD and UNLOAD utilities. The RACF® userid or group used for these jobs will require DB2 ADM authority on the CICS IA database.
