Memory Error in pre-processing phase MAIN_SHDRUN/ACT_UPG

[Former Member]

Hi All,

We are facing issues in Upgrade - Pre processing Phase for step MAIN_SHDRUN/ACT_UPG.

=========================================

The process stops with errors:

Checks after phase MAIN_SHDRUN/ACT_UPG were negative!

Last error code set: Detected 1671 aborted activities in 'ACTUPG.ELG'

Calling '/upgrade/SUM/SUM/abap/exe/tp' failed with return code 12,

check

/upgrade/SUM/SUM/abap/log/SAPup.ECO for details

tp used shadow connect

The SM37 Job: RDDMASGL is getting cancelled after few minutes with dump message: Internal session terminated with runtime error

SYSTEM_NO_TASK_STORAGE

or Internal session terminated with runtime error EXSORT_NOT_ENOUGH_MEMORY

I already tried by setting the profile parameters as per sap note:1387739

abap/heap_area_total = 10000000000

abap/heap_area_nondia = 10000000000

ztta/roll_area = 20000000

and have also stopped and started the shadow instance. Still I face

thesame dumps…

I have attached the ST22 dump logs and related files of SUM for

analysis.

Please help us solve the issue.

Santosh

Hi Santosh,

Your OS and DB Platform??

RAM & Swap Size??

Also, have you tried to update the Shadow Kernel Upto most recent patch level?

Also double check  those 3 profile parameters mentioned above that should be added to the instance profile of Shadow system.

Hi Rahul,

Operating System HPUX11.31

Database ORACLE 11.2.0.4

RAM is 16GB,SWAP Size is 40GB.

I have updated my shadow instance Kernel 742 release to 200 and also updated the tp to level 211 of SAP KERNEL 7.42 64BIT UNICODESAP KERNEL 7.42 64BIT UNICODE.

The parameters added are OK.Please guide further.

Stop and start the shadow instance manually & check the memory/CPU utilization while both the instance are running(main & shadow instance).Also check the below KBA:

As per the logs sent ,Your Swap Memory is not enough to run the both instance simultaneously.

As a work around, Have you tried to stop the main instance and then run only the shadow instance?

Also ask your OS team to increase the page size.In the log its clear that Page size should be main memory x 3. Know me what are the results.

I have stopped the main R3 instance, Now only the shadow instance is Up and running.

I have started the upgrade from the point it stopped, I see its running quite fine now, and It has gone by far the time it usually gives the memory dump. I am constantly monitoring the space and memory and till now I don't see much utilization.

Great!!!

For a fair solution,you should now increase your swap size.

Hello Santosh,

Please check Import log in SPAM.

I could see error are reported.

Apart from this did you get a chance to look at SAP note:-

1563583 - SYSTEM_NO_TASK_STORAGE, DBIF_RSQL_NO_MEMORY, EXSORT_NOT_ENOUGH_MEMORY
