TASID V5.21 tool



Full screen system information display and much more.

Download Description

Use the TASID system monitor to view system activity on a z/OS system. This information  includes active address spaces (batch jobs, started tasks, TSO users, and system tasks), ENQ activity and contention, initiator status on JES2 systems, and so on. Note that some options might not behave consistently or operate correctly on every level of z/OS. All available documentation is contained in the help panels, which you can access by pressing the HELP function key when on any panel within TASID.

This tool is available on an "AS IS" basis.


TASID V5.21 is an ISPF application and requires a minimum level of ISPF for z/OS 1.10 to run. TASID is unable to display LPAR information as of z/OS 1.11 regardless of whether RMF or an equivalent is running.

As of z/OS 2.2, some functions do not operate correctly. Selecting option 4, Initiator Status List, results in message:
Unsupported level
TASID could not find the PIT control block.

Installation Instructions

TASID is packaged in two different versions:
- one version has the panels included with the load module (the first two files on the download list)
- one version has separate data sets for the panels and load modules (the last three files on the download list)

Once you have downloaded the files for the relevant version, follow the installation instructions in the README file to install that version of TASID and invoke the program.
