Define ESM options for Operations Manager

To activate the use of an external security manager, you must set the ESM operand value to Y on the DEFOPTN command in the Operations Manager startup configuration file.
DEFOPTN ESM Y

Even with ESM set to Y, it is recommended that at least one user be given access to Operations Manager in case ESM must be set to "N" temporarily. Refer to Authority assignments with AUTH and external security for more information.

Refer to DEFOPTN Operands for more information on the available operands.
