Hi Dev,
Parameter 'rsdb/esm/buffersize_kb' controls the size of the exp/imp SHM buffer.
Documentation from RZ11 for this parameter is as follows:
-
The parameter defines the size of the ESM buffer in kB. The buffer
provides data storage in Shared Memory and is addressed with the ABAP
commands EXPORT TO / IMPORT FROM SHARED MEMORY und DELETE FROM
SHARED MEMORY. The commands are only effective locally; the buffers
of external application servers are not changed.
If the buffer is full, no further objects can be stored in the buffer.
-
On the other hand for the Export/Import buffer the relevant parameter is rsdb/obj/buffersize, for which documentation is as follows:
-
This parameter sets the size of the import /export buffer (KB).
The buffer is used for data storage in the shared memory and is
accessed using the ABAP commands EXPORT TO/IMPORT FROM SHARED BUFFER
and DELETE FROM SHARED BUFFER. The commands only affect the local
system. Buffers on external application servers are not
changed. If the buffer is full, old buffer objects are kicked out
when new objects are exported to the buffer.
-
The last sentence for each is different. Parameter values and some more information are listed in SAP note #702728.
