IOA Security Interface Support for Session Managers

Many MVS sites use product packages that enable multiple VTAM sessions to run simultaneously, thereby enabling users to alternate between different sessions. These packages allow users to perform a single logon to the session manager product, and then log on to other VTAM applications without having to specify the user ID and password. Using this method, users can skip the logon screen whenever they log on to the IOA Online monitor (IOAOMON1). For this purpose, logon data in free-form text is passed on to the VTAM application using the following command:

Copy 
LOGON APPLID(vtam_appl_name) DATA(tranid+userid+pwd)

where

  • vtam_appl_name is the name of the VTAM application

  • tranid is a 4-character IOA tran ID

  • userid is an 8-byte user ID

  • pwd is an 8-byte password or password phrase from 14 to 100 characters in length

Whenever the logon data field is specified and the user ID and password or password phrase was verified successfully, the IOASE09 security module notifies the caller not to display the logon screen.
