You can configure OTMA to start when IMS starts or you can start OTMA after IMS is running.
Prerequisite: Before you can
start OTMA, you must first specify the GRNAME execution parameter.
The GRNAME parameter identifies the XCF group
that OTMA uses for communications.
- To start OTMA during IMS startup,
specify OTMA=Y in either the DFSPBxxx PROCLIB member or the IMS control region JCL.
- To start OTMA after IMS is
running, specify OTMA=N, OTMA=M, or omit the OTMA parameter completely.
After IMS is running, issue the /START
OTMA command.
Note: The /START OTMA command
is recoverable. That is, if OTMA was started by the /START
OTMA command, IMS disregards
an OTMA=N specification and restarts OTMA during warm and emergency
restarts, even if OTMA=N or the OTMA parameter is not specified.
- To prevent IMS from
restarting OTMA during a warm or emergency restart after the /START
OTMA command has been issued, specify OTMA=M. When OTMA=M
is specified, IMS does not recover
the /START OTMA command during warm or emergency
restarts.
