Topas at this particular time (Tue Dec 13 22:39:53 PST 2011) is displaying 53% is utilized by db2sysc process. So please let me know from where I can find correct real time CPU utilization of db2sysc process.
How to identify the culprit process running under db2sys?
running on under it,please use the fallowing steps and sample outputs to identify a culprit process. The process id of the db2sys is 3810. Now we need to list a processes that currently running under db2sys We can see that process 3815 ( in example) is consuming high CPU
What is the process memory usage of the db2sysc process?
For example, assuming the db2sysc process id is 23527694, Before running “db2pd -memblock pid=23527694”, the process memory usage is: where SZ/RSS represents the size of the core image of the process and the real-memory (resident set) size of the process respectively, of which most are from the process heap.
Why is my private heap usage so high in DB2?
If you observe very high private heap usage for a db2 process such as db2sysc/db2fmp, you will need to check if you have run the command “db2pd -memblock pid=
How to gather DB2 support from IBM?
In Windows environment, login as “Administrator” and open “Db2 command Window as Administrator” and issue following commands. Replace [database name] with appropriate database name. After the commands were completed, gather db2support. Please refer following technote for detail procedure. 3. contact IBM technical support and provide materials.

This commands have been tested in Unix/Linux environment. When DB2 started and running there is a process ( db2sys) that contains a multiple threads running on under it,please use the fallowing steps and sample outputs to identify a culprit process. Command ps -ef|grep -i db2sys sample output: db2inst1 3810 3808 0 11:24 ? 00:00:01 db2sysc 0 (3810)

What is a DB2 process model?
The process model that is used by all Db2 database servers facilitates communication between database servers and clients. It also ensures that database applications are isolated from resources, such as database control blocks and critical database files.
Why use a multithreaded architecture for the DB2 database server?
There are many advantages to using a multithreaded architecture for the Db2 database server. A new thread requires less memory and fewer operating system resources than a process, because some operating system resources can be shared among all threads within the same process.
What is a DB2 firewall?
The Db2 architecture provides a firewall so that applications run in a different address space than the Db2 database server ( Figure 1 ). The firewall protects the database and the database manager from applications, stored procedures, and user-defined functions (UDFs).
