Question & Answer
Question
Why am I receiving an abend 23E AKEB during shutdown of my CICS Transaction Server for z/OS (CICS TS) 4.2 region? I am using CA SymDump.
The message I receive is: DFHSR0606 applid Abend (code 23E/AKEB) has been detected.
Answer
Using the following diagnostics, I was able to determine that this problem is a result of CA SymDump module IN25INST issuing a DETACH of a TCB that is not valid. To resolve the problem, you should apply fix RO66740 from CA Technologies.
The 23E abend indicates during processing of a DETACH macro, the system found an error in the input parameters. Register 15 contains a hexadecimal reason code that explains the error.
If you review the system dump taken for the 23E abend, the reason code in MVS Register 15 is x'00000008' which indicates that a DETACH of a TCB was issued. But, the TCB specified was not a subtask of the caller's TCB.
The PSW in systrace shows that a DETACH (SVC 3E) is issued from IN25INST +x'D50'. Register 1 contains the pointer of the TCB that IN25INST wants to DETACH. In browse mode you can see that register 1 points to an invalid TCB address.
Following are part of the systrace entries showing the DETACH request and the 23E abend:
IDENT CD/D PSW----- ADDRESS- UNIQUE-1 UNIQUE-2 UNIQUE-3 PSACLHS-
UNIQUE-4 UNIQUE-5 UNIQUE-6 PSACLHSE
SVC 3E 00000000_30CDAD52 00000004 B0CDAD30 00225080 Detach
07851000 80000000 ********R1
*SVCE D 00000000_01453508 00000008 84000000 8423E000 00000001
********R15 (Reason code)

*RCVY PERC 8423E000 00000008 00000001
*** abend code
In this case, R1 looks like this in browse mode:
00225080 D2884812 00004010 D28C5870 7DC44587 | Kh.... .K...'D.g |
********
You could use IPCS command SUMM FORMAT to format out all the MVS TCBs.
