Command to stop DB2 Immediately

A. -STOP DB2 MODE (FORCE)
B. -stop DB2 (FORCE)
C. stop DB2
D. shutdown Db2

Answer

The correct command to immediately stop a DB2 database is:

A. -STOP DB2 MODE (FORCE)

Explanation

This command will forcefully terminate the DB2 database manager and all DB2 database processes without waiting for applications to disconnect or transactions to complete. The key parts of the command are:

  • “-STOP DB2” is the base command to stop the DB2 instance
  • “MODE” is a required keyword before specifying the stop mode
  • “(FORCE)” is the mode option that causes an immediate shutdown, ending all in-progress work

The other command options listed are close but not quite correct:

  • Option B is missing the “MODE” keyword
  • Option C is the basic command to stop DB2 normally, waiting for applications to disconnect, not immediately
  • Option D uses “shutdown” instead of the proper “STOP” keyword and lacks the FORCE option for an immediate shutdown

So in summary, to immediately stop a DB2 database, use the command “-STOP DB2 MODE (FORCE)” with that exact syntax and keywords. This will abruptly terminate the DB2 instance right away.
