The RCDS is back-level.

You are trying to use an recovery control data set (RCDS) from an earlier CICS® VR release.

CICS VR stops.

Migrate your RCDS, or define a new RCDS using the instructions in CICS VR Implementation Guide and Reference. This problem might also be caused by an error in your STEPLIB and LINKLST.
