DB2 Version 9.7 for Linux, UNIX, and Windows

db2stop - Stop DB2® command

Stops the current database manager instance. db2stop can be executed as a system command or a CLP command.

If a db2stop operation in a multi-partition database is not completed within the value specified by the start_stop_time database manager configuration parameter, the database partitions that have timed out will be killed internally (all resources associated with the database partition will be removed). Environments with many database partitions with a low value for start_stop_time might experience this behavior. To resolve this behavior, increase the value of start_stop_time.
