Displaying OAM and OSREQ reason code information
« Reply #2 on: September 14, 2020, 02:02:00 PM »
You can display reason code information for the OAM and OSREQ macros directly from a console or a TSO session, as of APAR OA58344 for V2R3 or later. These commands can also be invoked via JCL to aid in automation of error information capturing in real time.

Implementing MFA? (Multi Factor Authentication)
« Reply #3 on: February 07, 2021, 10:38:49 AM »
There was a problem with mixed case passphrases during MFA Web authentication where MFA incorrectly folded a passphrase to uppercase, and is fixed in MFA 2.0 and MFA 1.3 with PTF UI66464.

Before upgrading to z/OS 2.4 run the OAM IVP.

It's very easy to set up, doesn't require much time at all.

http://www.odusergroup.org/forums/index.php?topic=887

This way you can determine early after the IPL of 2.4 whether OAM is correctly set up.  Also, it will assist in determining whether an issue is a CMOD problem or an OAM problem, hastening resolution of any issues.

Symptoms:

JES2 MAS.

Other members of the plex are already at 2.4.

Last member, which also happens to run CMOD, upgraded.

ARSYSPIN very slow ingesting from SPOOL.  (Could also affect ARSLOAD as a started task reading from SPOOL)

Cause:  JES2 error

A workaround is available that can be dynamically implemented, see the APAR description.
