Resource Recovery Service planning on z/OS

About this task

This is part of the larger task of customizing your z/OS® environment.

Start of changeIBM® Integration Bus for z/OS uses Resource Recovery Service (RRS) to coordinate changes to WebSphere® MQ and DB2® resources. Ensure that it is configured and active on your system, otherwise your integration node will be unable to connect to DB2.End of change

Start of changeEach integration server address space on z/OS that is configured for CICS® two-phase commit (globally-coordinated) transactions will register as a resource manager with RRS. The following planning considerations apply to each integration server address space that is configured for CICS two-phase commit:
  • The address space automatically becomes non-swappable to ensure that the RRS exits that are registered with RRS are available at all times.
  • The address space uses a single reusable System LX. There is a limited number of System LXs available on the z/OS system, and you must ensure that sufficient are made available. The parameter NSYSLX in IEASYSxx determines the number of System LXs that are available. See the z/OS MVS™ Initialization and Tuning Reference guide for further information. System LXs can be monitored in the IBM Health Checker by reviewing the value of IEA_LXS. For more information, see the IBM Health Checker for z/OS User's Guide.
