Enabling OTMA

To enable IMS to use OTMA, specify the z/OS® cross-system coupling facility (XCF) group name and IMS OTMA member name during system definition.

OTMA is installed with IMS TM. The IMS INSTALL/IVP Dialog is not used to install OTMA.

To start OTMA, you can use the OTMA=Y startup parameter in the IMS procedure during IMS system definition or, after an IMS restart, issue the type-1 command /START OTMA.

You can define various OTMA attributes during IMS system definition, including z/OS cross-system coupling facility (XCF) names, startup behavior, security, and so on.
