Thanks Juan for quick reply. But I am looking for some note to configure the memory parameter values in ECC 6.0. Due to some situation, I need to increase some of the parameters value, so, need to see recommendation of SAP on those memory parameters.

Maybe if you describe your scenario and current values we can make same suggestions.

Hi Juan,

Currently, as per configuration,

ztta/roll_area: 6500000

ztta/roll_extension: 8000000000

abap/heap_area_total: 8589934592

abap/heap_area_dia: 3000000000

abap/heap_area_nondia: 3000000000

em/initial_size_MB: 8192

Now, some big report is running and the job is failing for "No more storage space available for extending an internal table."

with dump: TSV_TNEW_PAGE_ALLOC_FAILED.

Now, planing to increase some correct memory parameters to correct values so that th job completes successfully.

Could you please suggest on which parameters values can be increased and how much?

Thanks & Regards,

Sujit.

Can you say how much memory you have, and how much applications running on this server (for example how much memory are presented for DB to). Your report are DIA or BTC ? Can you check in ST22 TSV_TNEW_PAGE_ALLOC_FAILED

the memory distribution ? In any case for so big ztta/roll_extension look's like very small em/initial_size_MB,

on Windows why you are not use ZAMM ? Note 88416 - Zero administration memory management as of 4.0A/ Windows

Ohhh this is coming from thread...

right? (Please close the previous thread)

Check

http://help.sap.com/saphelp_nw04/helpdata/en/02/96279d538111d1891b0000e8322f96/content.htm

basically the message is saying Extended Memory exhausted, check that your swap/page memory is at least 4 times the size of your RAM.

You can also increase abap/heap_area_* parameters but I'll first check that your EM settings are correct

SWAP is zero in central instance where the job is running. Any other memory parameter if want to know?

Let me know your suggestion which memory parameter can be incresed?

And, I will close the prevîous thread.

Thanks & Regards,

Sujit.

SWAP is zero in central instance where the job is running

Surely can't be 0.... I'm talking about the swap space at OS level (as page file size) not the SWAPS like in ST03.

I'm not Juan, but if can will write my opinion....

Can you say more detaily, are you BASIS administrator or not?

Can you explain

Physical memory: 130.937,0 MB

Current memory: 104.448,0 MB ??

Go for example to St06N and check from here, you not say how much apllications are running on this server, are BD on same server, may be you have any other SAP servers on this host to? MUCH information needed, but if you really have the

128 GB Physical memory , the 8 GB em/initial_size_MB look's like joke.

[JPReyes · Accepted solution]

Yes, agree with sergo... those values do not make sense at all.

1) Can you check phys_memsize are (check in rz11).

P.S. or check in ST02 --> SAP memory --> Extended memory

2) Can you post in ST22 --> open dump --> go to "error analysis" you will see like this : -->

How to correct the error

The amount of storage space (in bytes) filled at ter

Roll area...................... 6221152

Extended memory (EM)........... 1051651848

Assigned memory (HEAP)......... 2000778800
