See Installing DBCTL, and defining CICS and IMS system
resources. The following considerations
apply:
- CICS® installation is simplified, because there is no need to do a partial
system generation.
- In CICS resource definition, there are changes to:
- System initialization parameters.
- Monitoring control table (MCT) entries.
- CICS system definition (CSD) file entries.
- Program list table (PLT).
- Some DD statements are removed from CICS JCL, and some are changed because of
DBCTL.
- PDIRs are not needed for DBCTL. You define PSBs using IMS™ APPLCTN macros.
- DDIRs are not needed for DBCTL. You define DBDs using IMS DATABASE macros.
- New DBCTL startup parameters.
- DRA startup table parameters.
- Customization--user-replaceable program DFHDBUEX and DL/I global
user exits XDLIPRE and XDLIPOST. If you use CICS support for XRF, global user exits XXDFA,
XXDFB, and XXDTO are available to enable you to establish takeover decision
mechanisms for DBCTL.
System programmers should also:
- Set up procedures for operations and recovery
- Review use of DBRC
- Review use of data sharing
- Check exits
- Consider new problem determination techniques
- Consider new performance tuning techniques
