SAP ASE includes a number of configuration parameters that use moderate amounts of
memory.
Parallel Processing
Parallel processing requires more memory than serial processing.
Remote Servers
Some configuration parameters that allow SAP ASE to communicate with other SAP servers such as Backup Server, Component Integration Services, or XP Server, use memory.
Referential Integrity
If the tables in your databases use a large number of referential constraints, you may need to adjust the number of aux scan descriptors parameter, if user connections exceed the default setting.
Parameters That Affect Memory
Other parameters affect memory. When you reset these configuration parameters, check the amount of memory they use and the effects of the change on your procedure and data cache.
