Any ideas?

Hello Marian

This dump usually occurs related to  abap/shared_objects_size_MB . When I encounter this dump, I  set it to 200 and restart the system , then the problem is solved. You can check and if it is not enough you can set it to a higher value  ideally between 100 and 500 ( According to Sap Note 1294406 can be even set to 650 ).

Please check the values of other parameters that are explained in the following note also, that you already found, so if there are lower values they can also be increased and activated with the restart.

Hi all,

I had a similar kind of issue and resolved it.

First of all look at the ABAP dump and note down on which application server the dump is being thrwon.

Then we need to Add the following parameters in the instance profile of that application server.

abap/shared_objects_size_MB

em/global_area_MB

The default value of abap/shared_objects_size_MB = 20 and em/global_area_MB = 512.

You can keep em/global_area_MB as default and keep doubling the value of abap/shared_objects_size_MB until abap dump stops i.e. value should increase 40>80>160.

Hope this would be helpful.

Regards,

Shashidhar.

Hi,

Please check this parameter.

ztta/rool_first = 1

Hi Marian,

Your system needs parameter tuning, or in worst case resizing the hardware... please contact the Basis consultant to take a look at the ST02 stats....
