z/OS V2.5 Release Notes
« on: December 20, 2021, 08:52:21 AM »
OAM issue surfaced by CMOD:

OA62618: CBR9912I RSN9013 DURING OSMC OR OSREQ RETRIEVE REASON CODE X'80030200'
 
Error description
•   The issue may be surfaced in either of the following ways:  1)
•   During OSMC processing: CBR9912I groupxx CBRHRDAS A request to
•   read Object from collection  collection-name,object object-name
•   in groupxx  failed. The return code is 16, and the reason code
•   is 9013.  2) Failure from an application to OSREQ RETRIEVE an
•   affected object. The OSREQ REASON CODE returned to the
•   application is x'80030200'.  This issue occurs for a subset of
•   object sizes if BUFFER64 was used on the OSREQ STORE that stored
•   the object and the object was stored to the LOB table.
•   
•   IDENTIFICATION:
•   The following SPUFI may be run against each Object Storage Group
•   that utilizes LOB tables to identify objects affected by this
•   issue:
•   
•   SELECT 'GROUPxx', ODNAME, ODCLID, ODLOBFL, ODSIZE, LENGTH(OTOBJ)
•    AS LENGTH
•    FROM hlq.OSM_OBJ_DIR
•    LEFT JOIN hlq.OSM_LOB_BASE_TBL
•    ON OTNAME = ODNAME
•    WHERE LENGTH(OTOBJ) <> ODSIZE;
•   
•   *where hlq is the DB2 qualifier of the Object Storage Group
•   table being investigated
•   
•   If the ODSIZE is 1 byte greater than the length of OTOBJ and is
•   a multiple of (1048568 x n) +1, then the object is affected by
•   this issue.
•   
•   ADDITIONAL SYMPTOMS:
•   CBR9912I OSREQ ODSIZE

Contact OAM support for details and fix.

LE for COBOL issue.

Symptom is arsload started task can't be brought down with a normal STOP, has to be cancelled to terminate.

PH43756: Loop during thread termination starting with IGZETHT and involving repeated invocation of IGZXWAIT

During COBOL runtime thread termination in a multithreaded environment, IGZXWAIT is repeatedly driven waiting on a state that never arrives.

Content Manager OnDemand exposed the following issue:


After upgrading z/OS from 2.3 to 2.5 loading OnDemand AFP report in batch results in a loop along with looping ARSSOCK and ARSODF address spaces.

After cancelling the AFP load job that ran for 12 min instead of 1-2 seconds, ARS* address spaces continued to loop and had to be cancelled.

Attempted run of OAM cycle and OAM looped and would not finish processing the cycle and had to be cancelled (OSMC STOP command would not work).


Resolution:  APAR PH44548  in Query Monitor product

Got any old HFS files that haven't been converted to zFS yet?
« Reply #3 on: April 21, 2022, 08:10:53 AM »
In Marna Walle's 2.5 migration presentation she stated that 2.4 is the last level to support HFS. 

Here's the text accompanying the slide deck of her presentation.

Quote
z/OS 2.4 is the last release of the operating system to support the HFS (Hierarchical File System) data structure used by the z/OS UNIX environment.
 
IBM has provided equivalent if not superior functionality with the z/OS File System (zFS).

Customers should migrate from HFS to zFS using the utilities provided in the operating system to convert their entire file system hierarchy.

IF you try running an SSL test with CMOD

https://www.ibm.com/docs/en/zos/2.5.0?topic=2-system-ssl-module-verification-setup

AND IF CMOD fails with:
 
CEE3501S The module //GLDCLS64 was not found

CEE3501S The module //GSKC64F was not found

THEN you're missing the following:

FMIDs JRSL441 and JCTP451 which supply those 2 missing ++PROGRAM parts.
 
These are IBM® Tivoli® Directory Server for z/OS® (IBM TDS for z/OS) and SSL System Security Level 3
