SAP Error Message - Details

• Message type: E = Error

• Message class: TN - Support Package Manager (SPAM) Messages

• Message number: 595

• Message text: Optimization of the import queue requires &1 MB of memory

What causes this issue?

To optimize the import queue you require &V1& MB of main memory space.
The call to optimize the import queue takes place with a
parameterization after which only &V2& MB main memory space is to be
used. This is not however not possible due to the size of the import
queue.

System Response

The optimization of the import queue is executed with &V1& MB main
memory space that is actually required.

How to fix this error?

If the optimization of the import queue was completed successfully then
you can ignore this message.
If the optimization of the import queue is canceled due to a lack of
main memory space, proceed as follows:
Start the Support Package Manager (transaction SPAM) and choose the
"Execute in Background" option. There is usually more main memory
available for SAP background processes than dialog processes.
Start the Support Package Manager (transaction SPAM) on an application
server where more main memory is available or increase the memory space
availablez to the SAP work processes on the current application server.
Contact you system administrator for this.

Procedure for System Administrators

The &V1& MB main memory requirement named in the message does not fully
describe the main memory allocated by the work process since the work
process needs even more memory for internal processes. The value is only
a lower guide value.
Check and adjust the following system profile parameters. When changing
system profile parameters, note the memory administration
recommendations in the SAP NetWeaver Library:
For dialog processes:
abap/heap_area_dia
abap/heap_area_total
em/initial_size_MB
For background processes:
abap/heap_area_nondia
abap/heap_area_total
em/initial_size_MB
