Tailoring IMS systems that share data

Use the system definition macro and initialize the DBRC data sets and JCL to tailor an IMS system.

To tailor an IMS system to meet your data-sharing requirements:

• Use system definition macros to:
  • Include DBRC data-sharing support for IMS batch systems
  • Include IRLM (for block-level sharing)
  • Declare database access attributes
• Initializing DBRC data sets and JCL. See Initializing and maintaining the RECON data sets.
• Tailoring the execution JCL and virtual storage usage. See Tailoring execution JCL.
