I am reviewing idle time processing for TSO users. I found that the TSOTIME in the logonid record does not cause the TSO user to be timed out.

Issue/Introduction

Description:

There are basically 2 options that effect TSO TIMEOUT Processing: the JWT (Job Wait Time) and TSOTIME.

The JWT time parameter is specifically for idle time (how long an idle address space is allowed to wait before it is terminated) and is specified in the SYS1.PARMLIB(SMFPRMxx) member.

The TSOTIME specified on the ACF2 lid record and the GSO TSO TIME is the maximum allowed CPU usage and is only valid for TSO users.

Solution:

The TSOTIME specified on the ACF2 lid record and the GSO TSO TIME field are used for CPU time. At TSO logon time ACF2 passes the TSOTIME to TSO in the 'TIME=' parameter of the jobcard. The TSOTIME may be specified in the TSO full-screen logon display, the TSOTIME in the ACF2 logonid record or the GSO TSO TIME field. ACF2 will check for the TSOTIME specified in the following order and use the first supplied or specified TSOTIME value to be passed to TSO in the 'TIME=' parameter of the jobcard.

  1. The TSOTIME value that is entered via the full screen logon.

  2. The logonid TSOTIME value.

  3. The GSO TSO record TIME value.

The only way to override the JWT is by specifying 1440 for the TSO time, in doing so both the CPU time and idle time (JWT) are overriden and the user does not time out.

LOGONID record field:

*TSOTIME(time)
Indicates a user's default TSO time parameter, which is the CPU time limit (in minutes) associated with the TSO session. The maximum value is 1440. Zero indicates no default TSO time parameter was specified (Two byte binary field).

GSO TSO record field:

*TIME(0|nnnn)
Specifies the default time estimate for TSO sessions in minutes. If you specify zero, no TIME parameter is placed on the job statement. The default value is zero. The maximum value is 1440.

Details on the logonid record TSOTIME field can be found in the CA-ACF2 Security for z/OS Administrator Guide, Chapter 2: Controlling System Entry, section "Logonid Record Fields".

Details on the GSO TSO TIME field can be found in the CA-ACF2 Security for z/OS Administrator Guide, Chapter 14: Maintaining Global System Options Records section "Time-Sharing Options and Defaults (TSO)".
