How would you stop DB2 LUW on a Linux system?
Log in as the instance owner or as a user with sufficient privileges to stop the instance.

Open a terminal window and navigate to the instance home directory.

Run the following command to stop the instance:

db2stop force

Wait for the process to complete and for the message DB2STOP processing was successful. to appear.

Verify that the instance has been stopped by running the following command:

db2pd -db <database_name> -instance

The output should indicate that the instance is not active.

Note: You may need to run the above commands with root privileges if the instance owner does not have sufficient permissions.
