In Oracle 9i, Oracle database components can be stopped and started exclusively under the control of the Sun Cluster RGM. The effects of state changes to Sun Cluster resources for Oracle 9i RAC database instances are as follows:
Bringing online a resource for an Oracle 9i RAC database component starts the component on the nodes where the resource is brought online.
Taking offline a resource for an Oracle 9i RAC database component stops the component on the nodes where the resource is taken offline.
