Return codes

When the service returns control to your program, GPR 15 and return_code contain a hexadecimal return code, shown in the following table. If you need help with a return code, see the programmer at your installation responsible for managing RRS. Under information about working with application programs, z/OS MVS Programming: Resource Recovery contains additional details about these return codes.

RRS requested that the resource managers back out the changes to the resources. However, the state of one or more of the resources is not known.
RRS is not active.
The resource manager fails with an incomplete protected interest in the UR, or RRS fails before the UR is complete.

Action: The action by an application depends on the system environment. Some possible actions are:

Display a warning message to the end user.

Abnormally end the application because the resource manager will not allow any further changes to the resource until the situation is resolved.
