Hi

We have this error occasionally where the Java app server throws a error 
message saying connection time out.

Googling the error takes me to
http://www.redbooks.ibm.com/redpapers/pdfs/redp4080.pdf

And one of the interesting point there is 
You are driving more load than the server or back-end system has resources
to handle.
In this case, you must determine which resources you need more of and
upgrade configurations or hardware to address the need. One indication of
this problem is that the application or database server process is nearly 100%
busy.

Well how do i determine that the database server processes at that point of 
time was 100% busy or not ?
