Reply with quote

After some vendor upgrades to our online CPCS System. I'm starting to get some random S878 abends during application task execution. The help for S878 references Info APAR II05506 as a source of additional debugging information.

The problem is I can not find this APAR. I searched ibm.com and the web while it gives me hits that reference that APAR, it does not return the actual APAR.

My online system runs with a 300M Region, so there is plenty of storage available. Below is generally about 6.5 Meg Free with 298M Above. I'm hoping this APAR will assist me in tracking down how much storage is getting requested so I can pin down the root cause.

TIA.

Hello,

Try here:
http://www-01.ibm.com/support/docview.wss?uid=isg1II07347

Keep in mind that this is an Informational APAR.

That seems to be II07347. Does that supersede II05506?

And the real kicker here is that according the information in the IEA705I message the storage requested was 0xc8 bytes from subpool 16 (0x0010)

IEA705I 00F95700 008D1C90 008D1C90 00101200 000000C8

I'll have to see if there is anything useful in the partial SYSMDUMP I did get.

not too much hope to find it still around

LOCAL FIX:


PROBLEM SUMMARY:
THE FOLLOWING IS A WAY TO DEBUG ABEND80A / ABEND878 (OUT
OF STORAGE CONDITIONS). YOU WILL NEED A DUMP OF THE
ABEND TO PURSUE.
-
-
1. TO FIND THE FAILING GETMAIN REQUEST (THE LAST ONE THAT
WAS ATTEMPTED--REMEMBER THIS GETMAIN IS NOT ALWAYS THE
CULPRIT, IT CAN BE THE VICTIM OF SOMEONE ELSE EATING
UP STORAGE) YOU CAN EITHER:

UP STORAGE) YOU CAN EITHER:
A. FIND MESSAGE IEA705I (MSGIEA705I) IN THE SYSLOG OUTPUT.
THE MESSAGE IS FORMATTED IN THE MESSAGES MANUAL.
THE MESSAGE CONTAINS THE CURRENT ASCB ADDRESS,
THE DISPATCHED AND INPUTTED TCB ADDRESS, AS WELL
AS THE SUBPOOL NUMBER AND HOW MANY BYTES THE REQUEST
WAS FOR. PLEASE SEE THE MESSAGE MANUAL TO DEBUG.
B. LOCATED IN THE DUMP IS AN AREA IN THE ENUCLEUS THAT
VSM PLACES AN UNFORMATTED COPY OF THE MSGIEA705I.
TO FIND THE LAST GETMAIN REQUESTED, DO THE FOLLOWING
ON IPCS:
-
-
1. FORMAT THE 'CVT' CONTROL BLOCK BY GOING TO THE
COMMAND PANEL AND ENTERING 'CVTMAP'

THIS FIELD POINTS TO AN AREA IN THE EXTENDED NUCLEUS
THAT VSM USES AS A SAVE AREA FOR ERROR CONDITIONS. GO
TO THIS ADDRESS IN THE DUMP.

THERE ARE 3 SQA SUBPOOLS:
SP226 (USUALLY USED FOR IOS CONTROL BLOCKS) IS STORAGE
THAT RESIDES BELOW THE LINE ONLY. THIS SUBPOOL IS
USUALLY RELATIVELY SMALL (X'20000'-X'30000' BYTES).

SUBPOOL IS USED BY MANY PRODUCTS.
IF YOU CANNOT TELL WHICH SUBPOOL IS THE ONE THAT IS
ABNORMALLY LARGE, YOU MAY NEED TO TAKE A COMPARISON

HAVE AN 'OLD' DUMP WHEN THE SUBPOOLS WERE NOT LARGE? W
MAY NEED TO RESORT TO HAVING YOU TAKE A CONSOLE DUMP

ABNORMAL GROWTH IS. IF YOU HAVE ISOLATED THE SUBPOOL,
THEN CONTINUE TO THE NEXT STEP:

"VSM LOCAL DATA AREA (LDA) AT ADDRESS XXXXXXXX"
IF THE LDA CANNOT BE ACCESSED, THE DUMP DID NOT CONTAIN
LSQA FOR THE ASID THAT HAD THE STORAGE PROBLEM.

3. THE 'LDA' IS THE VSM ANCHOR CONTROL BLOCK FOR ASID'S.

3. THE 'LDA' IS THE VSM ANCHOR CONTROL BLOCK FOR ASID'S.
THERE IS 1 LDA PER ASID.
-
4. THE FOLLOWING FIELDS NEED TO BE OBTAINED EACH TIME
AN ASID RELATED STORAGE PROBLEM IS DETECTED:
-
LDA+
X'3C'= LDASTRTA (THE STARTING ADDRESS OF THE PRIVATE AREA
-


X'40'= LDASIZA (THE SIZE OF THE ENTIRE PRIVATE AREA)
-
X'4C'= LDAESTRA (THE STARTING ADDRESS OF EPRIVATE AREA)
-

X'50'= LDAESIZA (THE SIZE OF THE ENTIRE EPRIVATE AREA)
-
X'98'= LDACRGTP (THE CURRENT TOP OF THE REGION (ADDRESS))
-
X'9C'= LDAERGTP (THE CURRENT TOP OF THE EREGION (ADDRESS)
-
X'CC'= LDAREGRQ (THE REGION SIZE REQUESTED BY JOB)
-
X'D0'= LDALIMIT (THE IEALIMIT VALUE FOR BELOW THE LINE)
-
X'D4'= LDAVVRG (THE ADJUSTED REGION SIZE REQUESTED)
-
X'D8'= LDAELIM (THE IEALIMIT VALUE FOR ABOVE THE LINE)

BROWSE Item 1 of 1 selected items Line 418 of 537

-
X'DC'= LDAEVVRG (THE ADJUSTED EREGION SIZE REQUESTED)
-
5. FIND 'FBQEF' . THIS IS GOING TO BE FOUND
JUST AFTER 'ADDRESS SPACE REGION DESCRIPTOR DATA
FOLLOWS'. THE FBQEF IS ON A 'DUMMY' LINE, AND THIS
ENTIRE LINE CAN BE IGNORED.
HOWEVER, IF THERE IS ANY FREE CONTIGUOUS STORAGE IN THE
ADDRESS SPACE, THERE WILL BE:
'FREE BLOCK QUEUE ELEMENTS' LISTED UNDERNEATH THIS LINE.
EACH FBQE REPRESENTS STORAGE ON PAGE BOUNDRIES THAT IS
FREE.
THE TWO IMPORTANT FIELDS ARE:
SIZE (THE SIZE OF THE FREE STORAGE)
AREA (THE STARTING ADDRESS OF THE FREE STORAGE)

PF1=Help 2=RLOcate 3=ENd 4=TOP 5=BOTtom 7=BACKward 8=FORWard 9=PRInt
10=PREvitem 11=Nextitem 12=RETUrn EXPort LOcate LEft RIght PREFIX LIne

AREA (THE STARTING ADDRESS OF THE FREE STORAGE)
-
-
6. ONCE ALL OF THIS DATA IS GATHERED, MAP OUT THE STORAGE
ALLOCATED/FREE BY DRAWING A BOX AND FILLING IN THE
APPLICABLE ADDRESSES DENOTING WHAT THE ADDRESS SPACE
LOOKS LIKE AT THIS POINT IN TIME.
-
7. THE NEXT STEP IS TO CORRELATE THIS WITH THE ACTUAL
OUT OF STORAGE CONDITION THAT IS OCCURRING.
FOR EXAMPLE, IS THE OUT OF STORAGE CONDITION CAUSED BY
A LACK OF FREE STORAGE IN THE 'HIGH PRIVATE AREA SUBPOOLS'
(LSQA/SP229/230/236/237)? IF SO, WHY? DOES A SUBPOOL
HAVE ALL OF THE AVAILABLE STORAGE ALLOCATED TO THEM?
OR, DOES THE REGION ITSELF HAVE ALL OF THE ALLOCATED

OR, DOES THE REGION ITSELF HAVE ALL OF THE ALLOCATED
STORAGE, THUS SQUEEZING OUT THE HIGH PRIVATE SUBPOOLS.
-
*** SOMETIMES THIS IS VERY DIFFICULT TO DETERMINE, AND DO NOT
HESITATE TO CALL LVL2 TO ASSIST ***
-
8. ONCE THE AREA WHERE THE STORAGE PROBLEM HAS BEEN DETERMINE
(USER REGION VS HIGH PRIVATE), YOU WILL NEED TO GO TO THE
SUBPOOLS TO FIND OUT WHICH ONE HAS THE STORAGE ALLOCATED T
IT.


-
9. IF THE PROBLEM IS DETERMINED TO BE THAT A SUBPOOL
IN THE HIGH PRIVATE AREA HAS EATEN UP ALL OF THE AVAILABLE

PF1=Help 2=RLOcate 3=ENd 4=TOP 5=BOTtom 7=BACKward 8=FORWard 9=PRInt
10=PREvitem 11=Nextitem 12=RETUrn EXPort LOcate LEft RIght PREFIX LIne


BROWSE Item 1 of 1 selected items Line 460 of 537

IN THE HIGH PRIVATE AREA HAS EATEN UP ALL OF THE AVAILABLE
STORAGE, YOU WILL NEED TO GO BACKWARDS IN THE VSMDATA
TO FIND THE AMOUNT OF STORAGE ALLOCATED TO SP255 (LSQA).
DO A "F '*****' PREV " . THIS WILL TAKE THE
CURSOR BACKWARDS TO FIND THE AMOUNT OF STORAGE ALLOCATED
TO SP255.
(THE NORMAL ALLOCATION IN SP255 IS APROXIMATELY X'10000'
TO X'1F000'. IF LSQA LOOKS LIKE IT IS ABNORMALLY HIGH,
YOU WILL NEED TO INTERROGATE THE AQATS/DFE'S IN THE SAME
MANNER AS YOU WOULD FOR SQA (SEE THE BREAKDOWN OF
AQAT/DFE IN THE SQA DEBUGGING).
10. IF IT IS DETERMINED THAT IT IS NOT LSQA THAT IS CAUSING TH
STORAGE SHORTAGE SITUATION, HAVE THE CUSTOMER DO REPEAT
FINDS ON '*****'. VSM WILL FORMAT OUT THE REST OF THE
SUBPOOLS UNDER THE TCB THAT WAS CURRENT AT THE TIME OF

PF1=Help 2=RLOcate 3=ENd 4=TOP 5=BOTtom 7=BACKward 8=FORWard 9=PRInt

SUBPOOLS UNDER THE TCB THAT WAS CURRENT AT THE TIME OF
THE GETMAIN INSTRUCTION, SO YOU WILL FIND MULTIPLES OF
EACH SUBPOOL.
-
11. YOU WILL NEED TO WRITE EACH AMOUNT DOWN, AND THEN DETERMIN
WHICH SUBPOOL LOOKS ABNORMALLY LARGE. ONCE THE SUBPOOL
IS DETERMINED, YOU WILL NEED TO FIND OUT WHAT THE ALLOCATE
STORAGE IS COMPRISED OF.
-
12. MAP OUT THE DQE/FQE'S IN THE SAME MANNER AS FOR A CSA
STORAGE SITUATION (SEE THE CSA DEBUGGING FOR THE MAPPING
OF DQE/FQE'S) AND GO INTO THE ALLOCATED STORAGE LOOKING
FOR EYECATCHERS.
-
13. IF NO EYECATCHER IS EVIDENT, YOU MAY NEED TO TURN
