When you attempt to start a host transaction from TRS, the request may fail due to a host security violation. An expired password, incorrect password setup, or some other reason can cause the failure.
With PEM disabled, an LU 6.2 user cannot determine the exact cause of this security violation. SNA allows only a single error message to be returned to the error log, regardless of the cause.
With PEM enabled for TRS, if a host security violation occurs, TRS sends an error message to the client informing the user to execute a PEM RPC to obtain more information. The exact message depends on whether the request was made by an individual user ID or a transaction group’s user ID. For example, TRS returns the following error message if a security violation occurs as a result of a request made by an individual user ID:
34331, "The requested host transaction could not be started because of a host security violation. Please execute sgw_peminfopwd for more information."
