Controlling IMS

You can use the TSO Single Point of Control (TSO SPOC) to issue commands to control IMS and IMS resources.

Controlling IMS with the TSO SPOC application
You can use the TSO SPOC to issue operator commands in an IMSplex. The TSO SPOC application uses an ISPF panel interface and communicates with the IMS Operations Manager (OM). OM then communicates with all of the other address spaces in the IMSplex (for example, IMS) as required for operations.
Issuing Batch SPOC commands
You can use the Batch SPOC utility to submit IMS operator commands to an IMSplex. The Batch SPOC utility accepts any commands that are supported by the OM API.
Modifying and controlling system resources
You establish the initial settings of IMS resources during IMS system definition.
Enabling and disabling IMS functions
If an IMS function is not enabled by default, you can enable the function dynamically while IMS is running by issuing the UPDATE IMSFUNC command. Or, you can enable the function statically by defining the function as enabled in the DFSDFxxx member of the IMS PROCLIB data set, and then cold starting IMS.
Controlling log data set characteristics
You might need to tune and modify log data set characteristics after monitoring or after changing your requirements for system availability, integrity, or operator handling. You can change characteristics for the OLDS, WADS, and RECON data sets through the IMS commands.
Connecting and disconnecting subsystems
IMS can only connect to another subsystem if that subsystem is identified in the subsystem member in IMS.PROCLIB. You must specify the subsystem member name in the SSM EXEC parameter before an IMS subsystem can access databases in an external subsystem (another program executing in a z/OS® address space).
Commands for IMS operations tasks
You can use various commands to complete IMS operation tasks.
