Hi, most of the memory ressources is in the data cache which is configured by the db paramter DATA_CACHE (in 8kb pages). Sapdb does not use the data cache on start but will take it when needed. Also, don't forget the database kernel processes work in shared memory (same memory for all process) with only a few kb for private data. On Linux, if you type the "free" command you will see that the database takes only 50 Mb and not n x 50 Mb.

It would also help to limit the number of processes spawn at sap-db start. Everytime I run "top", my server says something like this.... [...] 428 sapdb 9 0 51380 50M 3692 S 0.0 10.0 0:00 db:TSTDB 429 sapdb 9 0 51380 50M 3692 S 0.0 10.0 0:00 db:TSTDB 430 sapdb 9 0 51380 50M 3692 S 0.0 10.0 0:00 db:TSTDB 431 sapdb 9 0 51380 50M 3692 S 0.0 10.0 0:00 db:TSTDB 432 sapdb 9 0 51380 50M 3692 S 0.0 10.0 0:00 db:TSTDB 433 sapdb 9 0 51380 50M 3692 S 0.0 10.0 0:00 db:TSTDB 434 sapdb 9 0 51380 50M 3692 S 0.0 10.0 0:00 db:TSTDB 435 sapdb 9 0 51380 50M 3692 S 0.0 10.0 0:00 db:TSTDB 436 sapdb 9 0 51380 50M 3692 S 0.0 10.0 0:00 db:TSTDB 437 sapdb 9 0 51380 50M 3692 S 0.0 10.0 0:00 db:TSTDB [...] Unfortunatly this is not the complete list of unused db-tasks ;-) What has to be done?
