RCT (Resource Control Table) to define DB2 Plan details.
CICS maintains a special table for DB2 plans as well called RCT(Resource Control table). The RCT table ties together the TRANSID, the user enters and the Db2 PLAN of the application program. Before you run CICS/COBOL applications that access DB2 database, an entry must be added in the RCT.
It contains Transaction Identifier and DB2 plan name. This table is used only when SQL statements are there in your transaction.
The RCT can be defined using the DSNCRCT macro to produce a macro table.
