RRS= parameter for procedures

Specifies whether (Y) or not (N) the registration and connection to z/OS Resource Recovery Services (RRS) should be made. Valid values are Y, or N. The default is N.

When using the z/OS® Resource Recovery Services (RRS) feature, be aware that the optional RRS archive log stream typically generates large amounts of additional logging to the z/OS logger. If you use RRS Archive Logging, monitor it closely for system log stream performance impact.

For Fast Path capable systems, if RRS=Y is specified then the storage for Fast Path EPST blocks is always page fixed, regardless of the contents of the DFSFIXxx PROCLIB member.

RRS must be set to Yes (RRS=Y) if you use WebSphere Application Server or WebSphere Liberty Profile Server and access IMS databases with type-2 IMS Universal Database resource adapter connectivity through ODBA or ODBM.
