Z Os Adcd 113 13 Work -

The phrase “z os adcd 113 13 work” is not a formal IBM term but rather a shorthand notation used by system programmers to reference a specific maintenance scenario involving RSU 113 (or similar identifier), component level 13 PTFs, and WORK dataset issues. Effective troubleshooting requires mapping these numbers to actual SMP/E entities via HOLDDATA analysis and SMF records. Organizations running z/OS should maintain a local translation table for such informal identifiers to reduce ambiguity.

z/OS ADCD 1.13.13 is a purpose-built, preconfigured z/OS (IBM mainframe) system archive used for education, testing, demonstrations, and development. It provides a complete, runnable z/OS environment (including middleware and sample workloads) as an ADCD (Academic Dev/Test) package that can be deployed on supported IBM mainframe or z/VM hosts. This report summarizes its purpose, components, typical installation and configuration steps, common use cases, operational considerations, and references for further study. z os adcd 113 13 work

Use the SDSF (System Display and Search Facility) command:

//STEP1   EXEC PGM=SDSF
//* Or from TSO/E: SDSF LOG

Look for messages resembling:

IEA995I SYMPTOM DUMP OUTPUT  - ABEND=113-13
   MODULE=IGC00113  OFFSET=000015A0
   DATA AT PSW  -...
   PROGRAM=YOURPGM  WORKAREA=07F2A000

Add STORAGE(ADDR,MAP) to your IEASYS00 parmlib member. This forces the system to maintain detailed storage allocation maps, making erroneous FREEMAIN attempts easier to trace.

z/OS uses storage protection keys to prevent one program from writing into another's area. If a program running in Key 8 (application) attempts to free a storage block allocated in Key 0 (system), the supervisor state logic triggers a 113-13 abend. In ADCD, some pre-configured started tasks may run with elevated privileges, accidentally crossing key boundaries. The phrase “z os adcd 113 13 work”

Many ADCD users compile C/C++ applications using LE (Language Environment). If a C routine passes a pointer to a local stack variable instead of a heap-allocated block to a system service that expects a FREEMAIN-able address, the result is a 113-13 abend.
