TSV_TNEW_PAGE_ALLOC_FAILED Shortdump , memory issue

678 Views

Hello,

We are facing one issue of Memory dump for one of the Background Job. The Job is fetching a very huge data and it is failing with the shortdump TSV_TNEW_PAGE_ALLOC_FAILED. I have asked application user to brake the variant of period and now he is running job for 1 single day. But since the amount of data volume is so huge, it is not going thru.

The short dump gives following information about memory parameter value:

The amount of storage space (in bytes) filled at termination time was:

Roll area...................... 6225552

Extended memory (EM)........... 1001392792

Assigned memory (HEAP)......... 2998638656

Short area..................... " "

Paging area.................... 24576

Maximum address space.......... 18446744048641535328

~

The termination occurred in line 1009 of the source code of the (Include)

1009 -> SELECT * FROM .............

~

Instance Profile Memory parameter values :

rdisp/ROLL_SHM 8000

rdisp/ROLL_MAXFS 16384

ztta/roll_area 6500000

ztta/roll_first 1

ztta/roll_extension 1000000000

abap/heaplimit 20000000

abap/heap_area_nondia 3000000000

abap/heap_area_dia 3000000000

abap/heap_area_total 6000000000

~

Please note that once we got the dump "SYSTEM_IMODE_TOO_LARGE" and we have set the abap/max_imode = four_gb.

~

Can any one help me to resolve this error ? how much memory I can assign ? How to calculate memory available and how to calculate memory required ?

The job is very important from business point of view and do not have time to optimize the code as of now.

Any help will be higly appreciated.

Thanks
