  Oracle Tips by Burleson

Oracle10g Grid Computing with RAC
Chapter 8 - RAC Administration

Unique Parameters (across instances)

 The next category of parameters uniquely identifies a particular instance. They specify the identifiers of the independent instance, and give independent characteristics to an instance. Table 8.2 shows these parameters, which need to be unique in the cluster.

Parameter

Description

INSTANCE_NAME

Specifies the unique name of this instance.

INSTANCE_NUMBER

Specifies a unique number that maps the instance to one free list group for each database object created with storage parameter freelist groups.

ROLLBACK_SEGMENTS

Allocates one or more rollback segments by name to this instance.

THREAD

Specifies the number of the redo thread to be used by an instance.

UNDO_TABLESPACE

Specifies the undo tablespace to be used when an instance starts up. If this parameter is specified when the instance is in manual undo management mode, an error will occur and startup will fail.

Table 8.2 Parameters Unique for each of the instances
