DD statements removed from CICS JCL in a DBCTL-exclusive environment
The following DD statements are not required in a DBCTL environment.
- DFSCTL
- For DBCTL, DFSCTL is not required. DBCTL owns the OSAM buffer pools, which are specified in DBCTL startup JCL and in the DRA startup parameter table. See Database buffer specifications and option parameters and Defining the IMS DRA startup parameter table.
- DFSRESLB
- For DBCTL, DFSRESLB is not required. DFSRESLB is replaced by the DRA dynamically allocating IMS.RESLIB as described in DD statements.
- IEFRDER
- Used to define DL/I batch logging. For DBCTL, DL/I logging is to the IMS log. See Defining IMS logging parameters.
- IMSMON
- With DBCTL, you can start and stop the IMS monitor dynamically. See Using the IMS monitor.
- IMSACB
- For DBCTL, IMSACB is in the DBC procedure and the DLS procedure. There are additional DD statements: IMSACBA and IMSACBB. One is the active library and the other is available for the IMS online change utility.
- DFSVSAMP
- For DBCTL, DFSVSAMP is not used. The information it contains, for example, VSAM buffer parameters and performance and trace options, is in the DFSVSMxx member of IMS.PROCLIB in the PROCLIB DD statement of the DBCTL startup procedure (DBC). The DFSVSMxx member must be available to DLISAS, which means that you must add a data set with member DFSVSMxx to the DLISAS address space. The last two characters of the DFSVSM member are a suffix, which you specify in the VSPEC parameter of the DBCTL startup procedure (DBC).
- RECON data sets
- RECON data sets are generally specified in DFSMDA IMS dynamic allocation members in the IMS.RESLIB library. See IMS dynamic allocation macro (DFSMDA). For DBCTL, RECON data sets can be specified in the DBRC procedure.
- JCLPDS
- For DBCTL, JCLPDS is in the DBRC procedure.
- JCLOUT
- For DBCTL, JCLOUT is in the DBRC procedure.
- Database DD statements
- Generally, you specify database DD statements in DFSMDA IMS dynamic allocation members in the IMS.RESLIB library. For DBCTL, they can be specified in the DLS address space for DL/I databases, or in the DBC address space for DEDBs.
