SSAS memory problem in querying


a question memory management in querying an ssas server.

 

it happens users make huge queries on unoptimized elements of cube.

the result on our server is memory usage grows fast, and far beyond totalmemorylimit specified on server.  

especially, specified 2.6gb totalmemorylimit, , performance graphs have show memory usage service exceeded 4.5gb for of these bad queries !

as result, paging explodes, , put system on low-memory conditions... since service runs on shared environment, causes troubles other services running there...

 

i understand momory limit kind of soft limit can exceeded, not !!!

i prefer bad queries are automatically killed service, replying not have enough memory complete...

 

is there way configure service way ?

 

hi

if haven't have @ following article

http://www.microsoft.com/technet/prodtechnol/sql/2005/ssasproperties.mspx

in particular following server properties

 

for query timeouts

servertimeout

 

memory clean up

totalmemorylimit

lowmemorylimit

 

also depending on usage realistically need have ssas on dedicated server. performance tuning art , variables huge. please let me know how on above , can try else
