Question from satish on Sep 11 at 12:08 AM Dear Gurus
We are on ECC 6.0 32 bit, Kernel 7.20/600, Oracle 10.2 Windows 2003
Enterprise edition 64 bit OS.
We are getting large number of dumps of SYSTEM_NO_TASK_STORAGE in ST22 in
our production server after upgrading kernel to 7.20. We have tried to
overcome the problem but could not succeed, hereunder the rz10 parameters
and dump for reference. Kindly suggest the parameter value.
Satish
Dump
-------
What happened?
Each transaction requires some main memory space to process
Application data. If the operating system cannot provide any more
Space, the transaction is terminated.
What can you do?
Try to find out (e.G. By targeted data selection) whether the
Transaction will run with less main memory.
If there is a temporary bottleneck, execute the transaction again.

If the error persists, ask your system administrator to check the
Following profile parameters:
O ztta/roll_area (1.000.000 - 15.000.000)
Classic roll area per user and internal mode
Usual amount of roll area per user and internal mode
O ztta/roll_extension (10.000.000 - 500.000.000)
Amount of memory per user in extended memory (EM)
O abap/heap_area_total (100.000.000 - 1.500.000.000)
Amount of memory (malloc) for all users of an application
Server. If several background processes are running on
One server, temporary bottlenecks may occur.
Of course, the amount of memory (in bytes) must also be
Available on the machine (main memory or file system swap).
Caution:
The operating system must be set up so that there is also
Enough memory for each process. Usually, the maximum address
Space is too small.
Ask your hardware manufacturer or your competence center
About this.
In this case, consult your hardware vendor
Abap/heap_area_dia: (10.000.000 - 1.000.000.000)
Restriction of memory allocated to the heap with malloc
For each dialog process.
Parameters for background processes:
Abap/heap_area_nondia: (10.000.000 - 1.000.000.000)
Restriction of memory allocated to the heap with malloc
For each background process.
Other memory-relevant parameters are:
em/initial_size_MB: (35-1200)
Extended memory area from which all users of an
Application server can satisfy their memory requirement.
Note which actions and input led to the error.
For further help in handling the problem, contact your SAP administrator
You can use the ABAP dump analysis transaction ST22 to view and manage
Termination messages, in particular for long term reference.
Ror analysis
A new storage area of 809336 bytes was requested
(storage calss TASK).
All the available space has been used up.
