SQL 2000-SAP Note 327494

SQL 2005-SAP Note 879941

You can set the SAP parameter setting on both of the application server subject to the available RAM.

Thank you.

Kind regards,

Hi Eduardo,

You can change following parameters in the instance profile using transaction RZ10

em\initial_size_MB

PHYS_MEMSIZE (Only relevant for Windows NT)

System will need to be restarted

There are some other users who asked the same question, make a search and you will find more detailed information.

Hope this help!
