Restrictions

1. No FRRs may be set when calling to disconnect a space which is connected as a server manager with server type = routing.
2. If the key specified on IWMCONN was a user key (8-F), then the following must ALL be true:
   • caller must be in non-cross-memory mode (P=S=H). This implies that the current primary must match the primary at the time that IWMCONN was invoked. Running in a subspace is not supported.
   • must be in TCB mode (not SRB)
   • current TCB must match the TCB at the time that IWMCONN was invoked.
3. This service should not be invoked while in a RTM termination routine (resource manager) for the TCB owning the connect token since MVS™ will have its own resource cleanup routine and unpredictable results would occur. It is legitimate to use this service while in a recovery routine, however, or in mainline processing.
