Hi All
My enviroment is ERP6.0/Oracle 10.2.0.2/Solaris 10 SPARC 64bit.
Of late there have been memories issues with the DEV system which is hanging on a regular basis. A check at ST22 show this error 06.07.2011 14:59:26 DEV_DEV_01 DDIC 000 C TSV_TNEW_PAGE_ALLOC_FAILED
The SAP system is installed on a unified storage. In my internal disk I'm short of space for creating an additional swap file & I'm thinking of creating a 20GB filesystem on the storage for swap . Is it OK if I configure swap file in the external disk (storage) ?
below is the output of df -h of my disk

This error means that the application (workprocess) reached the maximum configured amount of memory.
This is not a storage or swap problem but solely a configuration problem.
I would first, before changing any parameters, contact the user who creates those dumps and ask him, if it's possible to reduce the amount of data. In most cases it's just a lack of selection criteria or people wanting to "download data" from SE16 or download huge spools from SP01.
If you need the have those programs ran through you need to adapt the parameters
abap/heap_area_dia (if it's a dialog process)
abap/heap_area_nondia (if it's a background process)
abap/heap_area_total

Secondly how do I adjust the two parameters below ?
abap/heap_area_nondia
abap/heap_area_total
These parameters cannot be adjusted dynamically from RZ11 and neither can I see them in the default, start & instance profiles when I ran transactions RZ10

Can you check how much memory is allocated at that time? This is also written in the dump.
Seems you started your monitoring jobs as user DDIC?

If you don't "see" them there, then they use the default of 2 GB. They are not dynmiacally changable in RZ11 but using the program RSMEMORY (start from SA38).
It would be interesting to see how much memory is allocated at the time they dump.

Forgot to tell you my physical RAM is 8GB & i have 3 swap files of sizes 8.8GB, 9.8GB & 8.7GB
Below is the info you requested
-
Error analysis
The internal table "\FUNCTION-POOL=STAM\FORM=NODETAB_FILL\DATA=LT_NODETAB_FULL"
could not be further extended. To enable
error handling, the table had to be delete before this log was written.
As a result, the table is displayed further down or, if you branch to
the ABAP Debugger, with 0 rows.
At the time of the termination, the following data was determined for
the relevant internal table:
Memory location: "Session memory"
Row width: 2160
Number of rows: 0
Allocated rows: 4
Newly requested rows: 4372 (in 1093 blocks)
Last error logged in SAP kernel
Component............ "EM"
Place................ "SAP-Server DEV_DEV_01 on host DEV (wp 28)"
Version.............. 37
Error code........... 7
Error text........... "Warning: EM-Memory exhausted: Workprocess gets PRIV "
Description.......... " "
System call.......... " "
Module............... "emxx.c"
Line................. 1881
The error reported by the operating system is:
Error number..... " "
Error text....... " "
-
How to correct the error
The amount of storage space (in bytes) filled at termination time was:
Roll area...................... 6221248
Extended memory (EM)........... 0
Assigned memory (HEAP)......... 2000960
Short area..................... " "
Paging area.................... 32768
Maximum address space.......... 18446744058020205680
If the error occures in a non-modified SAP program, you may be able to
find an interim solution in an SAP Note.
If you have access to SAP Notes, carry out a search with the following
keywords:
"TSV_TNEW_PAGE_ALLOC_FAILED" " "
"SAPLSEU_COMPONENT" or "LSEU_COMPONENTU01"
"RS_COMPONENT_VIEW"
If you cannot solve the problem yourself and want to send an error
notification to SAP, include the following information:
1. The description of the current problem (short dump)
To save the description, choose "System->List->Save->Local File
(Unconverted)".
2. Corresponding system log
Display the system log by calling transaction SM21.

This is not much memory - so the reason for the dump is not (as usual) the 2 GB default setting but the fact, that there is no more memory available.
It seems that at the time that dump occurs another process/user is using up all the memory, the system tries to allocate more in the heap but failing because it is also used up.
The next time that dump happens check in ST02 the actual memory usage of extended and heap memory.

The dumps happen in quick succession & the system will hang continously for about 3 to 5 minutes. When this happens it will be virutally impossible at that moment to execute transaction st02. seet time stamps below from st22

is it prudent to adjust memory parameters using RSMEMORY ?

Just check how much memory is used in ST02 - not at the SAME time but around that time. how much extended and memory are allocated and how much is left?
Changing the parameter will most likely not change anything because there seems to be no more memory left. In fact this may increase the number of dumps.

The situation has not recured but I'm sure it will before end of the day. I willl post those memory parameters immeidately after the system hangs
For the moment I've posted the extended & heap memory for the current time
