Using Multiple Console Support (MCS) consoles

You can enter IMS™ commands from Multiple Console Support (MCS) or Extended Multiple Console Support (E-MCS) consoles.

Use the CMDMCS keyword for the IMS, DBC, or DCC procedures during IMS system definition to enable commands to be entered from MCS or E-MCS consoles.

In a DB/DC environment, if Multiple Console is enabled (CMDMCS other than 'n' specified), IMS commands can be entered from an MCS or E-MCS console by prefixing the command by either the CRC or IMSID. For example, if the CRC is '#', a valid command would be #DIS A. If the IMSID is 'IMSP', a valid command would be IMSPDIS A.

Each segment of an IMS command must begin with one of the following:

The command-recognition character for the IMS subsystem
The IMS ID of the IMS subsystem

For multisegment commands, each segment, except the last, must end with the command recognition character or IMS ID followed by the ENTER key. The last segment must end with only the EOM (end-of-message, or ENTER) character.

You can send commands to all the IMS systems in an IMSplex by using an automated operations single-point-of-control (SPOC) application that sends commands and receives the responses to those commands through the Operations Manager (OM) application programming interface (API).

When you are using a Resource Manager (RM) structure in an IMSplex, it is best to issue commands to the Operations Manager (OM) through the TSO SPOC.
