Best Practise Cognos Configuration 10.2.2 for 64bit | JVM Problems

[Fleschgordon]

hi

we have problems with our Cognos Server 10.2.2. Its running on Windows Server 2012 64 bit. We use dqm with 64 bit.

We are migrating reports to that server and we have some problems:
The query was canceled because the server is low on memory
OR
Unable to execute the request because there were no connections to process available within the configured time limit.
----------------
Are there any Information Available about the Configuration ?

Now we increased the JVM Settings for the query service, but we don't know what is usefull.

Any hints and infos are greatly welcome.
Thx
