Oracle9i Database Reference Release 2 (9.2) Part Number A96536-01 |
|
Initialization Parameters, 7 of 222
ACTIVE_INSTANCE_COUNT
enables you to designate one instance in a two-instance cluster as the primary instance and the other instance as the secondary instance. This parameter has no functionality in a cluster with more than two instances.
When you set this parameter to 1, the first instance you start up becomes the primary instance and accepts client connections. The second instance starts up as a secondary instance and can accept client connections only if the first instance fails. In such an event, the secondary instance becomes the primary instance.
When the failed instance can once again be started up, it starts up as the secondary instance, and will not accept client connections unless the current primary instance fails.
