Define the CICS/DB2 connection and control characteristics using the CICS Resource Definition Online (RDO). You can still assemble macro resource control tables (RCTs) for migration to the DFHCSD file only. The DSNCRCT macro is shipped with CICS to allow migration of RCT tables to the CSD.
Note: For more information about DSNCRCT, see the CICS Resource Definition Guide.
The RCT or DB2 attachment facility contains the information required for CICS to establish its connection to DB2. The FILE transaction's DB2 facility lets you view information and statistics on each entry in the active RCT. The display format is presented as if the RCT existed as a DB2 table. This display is similar to the information provided by the IBM-supplied DSNC DISP STAT command, providing complete and easily accessed information.
To display the RCT, type the keyword DSNCRCT in the DB2 command area.
Versions and releases of CICS from the CICS transaction server for OS/390, Version 1 Release 3 onwards do not support running the CICS DB2 attachment facility using the RCT. Therefore, CA InterTest for CICS no longer supports the CORE=RCT command and produces the following message:
