You can quiesce a running
OLAP server by using the QUIESCE SERVER statement.
The QUIESCE SERVER statement
provides a deferred shutdown of the current OLAP server. After all
open sessions have been closed, the OLAP server will shut down. Other
OLAPOPERATE commands can be executed until the last open session is
closed and the OLAP server stops. After the OLAP server stops, the
only command that can be executed is a CONNECT command to connect
to another server.
