Sending commands to IMS DB

In an IMS DB warm standby or IMS XRF environment, a CCTL can use a z/OS® SVC 34 to broadcast an emergency restart command to an IMS DB alternate, or a SWITCH command to an IMS XRF alternate in order to have the IMS alternate system become the primary IMS system.

These are the only IMS commands that can be done using this interface. The command verb can be preceded by either the command recognition character or the 4-character IMS identification that is in the PAPLDBCT field of the INIT PAPL.
