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.
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.
What is the percent utilization of a CPU?
CPU percent utilization represents how much of the total CPU’s processing power is currently being utilized. The CPU usage may increase with running performance tests with a higher number of virtual concurrent users.
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=
What causes memory paging in db2pd?
Thus while db2pd walks through the heap, you may see the physical memory or virtual memory usage of the heap is increasing a lot especially when there used to be a lot of free memory pages in the private heap, and sometimes physical memory usage can grow significantly and cause memory paging to occur.

Therefore in order to dump all DB2 memory block information in the db2sysc process heap, db2pd can be very intrusive in a way that it has to walk through the entire heap to look for all memory blocks allocated by DB2. As a result, db2pd needs to read and check all private memory pages which may include those that used to be free.
How to collect DB2 memory block details for private memory set?
In some cases you may want to collect DB2 memory block details for the private memory set used by DB2, for example, to diagnose if there is memory leak in DB2 private memory set, you may need to run the command “db2pd -memblock pid= ” to dump all DB2 memory blocks in the private set.
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.
What is a MySQL dump in DB2?
A Mysql dump is called a backup in DB2. It creates a binary file that you can restore in the same kind of platform (Window, Linux). It contains the tables definition (DDL), the data and the security. and 3. There is another command that just extract the DDL of the defined objects. The tool is called db2look.
What causes memory paging in db2pd?
Thus while db2pd walks through the heap, you may see the physical memory or virtual memory usage of the heap is increasing a lot especially when there used to be a lot of free memory pages in the private heap, and sometimes physical memory usage can grow significantly and cause memory paging to occur.

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.
Logon to the database server as administrator user. Open “DB2 Command Window – Administrator” Run db2support command as below: db2support [outputdir] -s -d [database] -c -f > db2support.log 2>&1 Where [outputdir] is the path name to place output file (for example C:\home\db2inst1\db2support) note: The path name should not contain blanks.

pmap > pmap. check for the heap size in there. Typically, the heap is mostly used by authentication routines. DB2 memory allocations mostly reside in the Shared or “anon” mmapped regions of the process address space. I am not aware of encryption driving higher mallocheap usage as typically DB2 manages its own memory and does not use malloc heap.

Why does ‘used heap memory’ keep increasing?
Why ‘Used Heap Memory’ keeps increasing even after the application has started up and have not received any requests yet? (Image 1) Something in your JVM is creating objects. You would need a memory profiler to see what is doing this. It could be part of Swing, or yoru application or another library.
How are memory usage restrictions enforced for DB2 database products?
For Db2 database products with memory usage restrictions, the AUTOMATIC setting enforces a limit based on the lower of a computed value (75-95% of RAM) and the allowable memory usage under the license. See instance_memory for details on when it is enforced as a limit.
What determines the amount of shared memory used by db2sysc?
Shared memory used by the db2sysc process is directly a function of number of databases that are active at that time within that instance. Also the number and size of buffer pools being active at that time which is the main shared memory consumer.
