The mainframe may or may not require a full user ID and password complement for every requested transaction. When defining an RPC to TRS even when security is not enabled, you can specify the level of security information that best matches its mainframe component. Your choices are:
none – TRS passes the request to the mainframe without any user ID or password.
userid – TRS passes the user ID to the mainframe along with the request.
both (user ID and password) – TRS passes the user ID and the password to the mainframe along with the request.
