TSV_TNEW_PAGE_ALLOC_FAILED

Error analysis:

No more storage space available for extending an internal table.

The internal table "" could not be

further extended. To enable error handling, the table had to be delete before this log was written.

ABAP heap memory has been reached ,so it could not allocate more memory to extend the table.

Roll area...................... 5120272

Extended memory (EM)........... 4001612304

Assigned memory (HEAP)......... 10498192

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

Paging area.................... 32768

Maximum address space.......... 4294967295

The memory allocation sequence is

1) roll_first

2) Extended memory

3) Roll area and then

4) Heap i.e private memory

i checked the parameters ztta/rol_first = 1024 and ztta/roll_area=6500000 the difference is greater than 5120272 i.e the limit is not reached so how cum heap memory is assigned

2nd Question What exactly OS swap space??

Also suggest some reading material for memory management

This parameter can also affect your roll memory:

ztta/max_memreq_MB. You can assign all the memory you want to your roll and it won't take more than this. It's 64MB by default.

Hope this helps.

This error is reoccurring in the system

at first it was ignored as a temporary problem

but it is reoccurring in the system

the system has got enough memory configured

In st02

Roll area of 3MB is allocated

Extended area of 4GB

heap area of 2 GB

which quite sufficient

also virtual memory of 7GB is allocated at start

Also configured physical memory is 76Gb and swap space is 33 GB respectively

Hi Ameya,

is this the one time error or is it happening frequently.

If it is jus a one time u can ignore this as it might some times when a prgram consumes a lot of memory

for memory managemnt in SAP

please refer to http://help.sap.com/saphelp_nw04/helpdata/en/02/962acd538111d1891b0000e8322f96/frameset.htm

It is highly useful

OS Swap space- Swap space is an area on disk that temporarily holds a process memory image. When physical memory demand is sufficiently low, process memory images are brought back into physical memory from the swap area on disk. Having sufficient swap space enables the system to keep some physical memory free at all times.

Swap must be ideally 2 times the RAM

for more info. you can refer to

http://en.wikipedia.org/wiki/Paging#Tuning_swap_space_size

Hope it helps

Well not dat frequently

So Rohit it may be like ,suppose dat the entire internal table was copied into the RAM and the program was updating or inserting into it and it got full,hence needed to be extended at runtime but memory was exhausted rt

The h/w is System Model: IBM,7040-671

AIX Operating system

Yes Ameya,

one more thing check if it is happening with z program or SAP program

If it is Z Program ask your ABAPers to tune the report

Also ask your people to run reports which consume large memory in background because what happens iis people run the programs in dialog which consume a lot of memory and hence these dumps come which are not actually due to system's fault

Thanks for the info Rohit!!

Yeah i know we cant do anything for Z programs

Not enough information, what is your OS, Database, Hardware becuase this is a common error in SAP. So you need to see all the prospective for a clear vision about the memory problem.

Sap application used shared memory concept where Physical +Virtual(swap) memory has been used for program execution.

You can get a lot of notes and help just have a search.
