The dsmtop(Database Server Manager) command

-

The dsmtop command is a text-based monitoring tool similar to the db2top command. The dsmtop command uses MON_GET_* table functions to gather monitoring information. MON_GET table functions are built on a low overhead, lightweight monitoring infrastructure, so it is highly recommended to use dsmtop instead of db2top on databases that are running on version Db2 10.1 and higher.

The dsmtop command can provide information about:

Sessions: The connections that are active, blocked, or idle.

SQL statements: Recently executed SQL statements. The tool also provides a drill down to see the full SQL text or to run an explain on a statement.

Top consumers: Connections or activities are consuming the most CPU, IO, or another resource.

Time spent metrics: The breakdown of overall time spent by the database.

You can invoke the dsmtop tool by running the following command:

dsmtop -d <DBNAME> -n <HOSTNAME> -r <PORT NUMBER> -u <USER NAME

How to fix DB2 Tablespace OFFLINE state issue?

Method1: We can execute below DB2 commands to take off tablespace's OFFLINE state.   db2 terminate db2 force application all db2 connect to <database_name>   Method 2:  Perform ALTER Tablespace command to bring the tablespace up while the rest of the database is still up...

How to determine fenced User-ID of a DB2 instance

-
When you create a DB2 instance in Unix, you have the option of specifying a fenced user-id different than instance owner. The purpose of fenced user id is to protect DB2 from untested or malicious code from the external stored procedures, user defined functions etc. When you try to run these external procedures, they run in a separate address space owned by the fenced user id.   You know about the fenced user id if you created a DB2 instance yourself on your Unix platform. But suppose, you are looking at a DB2 instance created by someone and you are wondering as which is the fenced user id, you can look at the user and group id of the file .fenced in ~/sqllib/ctrl directory and this will tell you as which is the fenced user id. For Eg:/home/db2inst1/sqllib/ctrl/.fencedID It will display the fenced user id for the instance db2inst1   Another method to find the fenced user id is   db2pd -fmp
