OTMASE= parameter for procedures

Use the OTMASE= parameter in procedure to specify the type of OTMA RACF® security that you want to use. Valid values are C, F, J, N, and P. The default is F.

Valid parameter values include:

C: OTMA RACF security is CHECK. IMS commands are checked against the CIMS class. IMS transactions are checked against the TIMS class.
F: OTMA RACF security is FULL. This is the same type of security as CHECK, but additional security checking is performed against dependent regions. The default value is F.
J: OTMA RACF security is JOIN. OTMA performs connection authorization for OTMA clients by using the RACF Facility class IMSXCF.xcfgroup.member profile, if it exists. Transaction and command security is not enabled. No calls to RACF are made for IMS transactions and commands.
N: OTMA RACF security is NONE. No calls to RACF are made.
P: OTMA RACF security is PROFILE. Each OTMA message defines the level of security checking to be done.

The /SECURE OTMA command overrides the value you specify in the OTMASE= keyword.

If no value is specified, a value of X appears in the initial DFS1929I message that is issued when IMS is started. During IMS restart processing, this value is changed to F. A value of F appears in the active DFS1929I message that is issued when restart processing is complete.

If you do not specify the OTMASE keyword, IMS retains the OTMA security settings (which are established by the /SECURE OTMA command) after a warm start or an emergency restart.

After the OTMA client connection is authorized, the transaction or command security checking will be performed based on the security setting in the LUY_RACF_OPT of the message prefix which is set using the OTMA security level. For OTMA security level JOIN (J), the security setting in the message will be NONE for transaction and command processing.
