This parameter is applicable in a partitioned database environment only. It specifies the time, in minutes, within which all database partition servers must respond to a DB2START or a DB2STOP command. It is also used as the timeout value during an ADDNODE operation.
Database partition servers that do not respond to a DB2START command within the specified time send a message to the db2start error log in the log subdirectory of the sqllib subdirectory of the home directory for the instance. You should issue a DB2STOP on these nodes before restarting them.
Database partition servers that do not respond to a DB2STOP command within the specified time send a message to the db2stop error log in the log subdirectory of the sqllib subdirectory of the home directory for the instance. You can either issue DB2STOP for each database partition server that does not respond, or for all of them. (Those that are already stopped will return stating that they are stopped.)
