Starting or restarting IMS

Starting or restarting an IMS subsystem means initializing the IMS control region.

To restore the operating environment, the MTO must ensure the following are also initialized:

• All IRLMs
• All CQSs
• Any dependent regions (including utilities)
• All CSL address spaces (OM, RM, and SCI), if operating as an IMSplex using CSL
• Any connections to VTAM®
• All communication lines and terminals

The term MTO used in this information refers to the IMS master terminal operator for the DB/DC and DCCTL environments, and to the operator for the DBCTL environment. All commands shown assume that the command-recognition character is the forward slash (/).

See IMS Version 15 Operations and Automation for additional information.
