EXPORT NO_SHARED_MEMORY ABAP Dumps

[Former Member]

Hello,

PRD system is generating ABAP Dumps EXPORT SHARED_NO_MEMORY.

As per the dump the ESM shared memory is affected.

We increased the values of the following parameters in one of the appservers

rsdb/esm/buffersize_kb 8192

rsdb/esm/large_object_size 16384

and in rest of the appserver we just restarted the system and the buffer got flushed up and the availability was again 100%.

But again the buffers are filling up now, we feel in next 3-4 days will need one more reboot of the servers, but it being production system it is not advisable.

When we check this ESM buffers in other production system it works fine. the values remain constant.

But only in the PRD system the buffer is showing an decreasing trend, the buffers are not getting flushed.

The decreasing trend could be due to some expensive SQL statements,or background jobs.

Just wanted to know if there is any batch job which flushes out this buffer when used,

or we need to maintain the values of buffer so high that till the next outage it survives.

But in last 2 months we have not increased the buffer values, its only now the issues have come up.

or it is some issues with OS level.

Please let us know about it.

Thanks

Check following links and make sure you have paging file size 3 - 4 times of your RAM

Issue with custom program, there were no free statements in the code.

As a result of this it was not freeing up the buffer space.

Please always check buffered objects button. There you will find which objects are taking up the space.

Please involve ABAP guys here, they would be able to look into the object.

Thanks

How much Paging Memory you have configured in the system. It is advised that the Paging should be Equal to the Physical memory of the SAP Server. Also check any Table are buffered in the Main memory.

You need to check with your ABAP Developers if they can tune the Expensive SQL statement.
