CICS tasks

The database resource adapter (DRA) is the interface between DBCTL and the transaction management subsystem. You need to put the DRA startup parameter table (DFSPZPxx) and the DRA startup router program (DFSPRRC0) in the CICS® STEPLIB data set.

This topic describes CICS tasks associated with using DBCTL and CICS. The high level tasks include:

Procedure

  1. Define DRA resources
    Example: 
    //STEPLIB  DD DSN=CICSTSxx.CICS.SDFHAUTH,DISP=SHR
//         DD DSN=IMS.SDFSRESL,DISP=SHR

  2. Connect CICS to DBCTL

    After CICS has been started, the CICS operator can issue a CONNECT command to DBCTL through the CDBC transaction. This transaction is also used for disconnecting from DBCTL. The CDBI transaction provides the status of the connection.
