RC_DATABASE_INCARNATION

This view lists information about all database incarnations registered in the recovery catalog. Oracle creates a new incarnation whenever you open a database with the RESETLOGS option. Records about the current and immediately previous incarnation are also contained in the V$DATABASE view.

Column	Datatype	Description
`DB_KEY`	`NUMBER`	The primary key for the database. Use this column to form a join with almost any other catalog view.
`DBID`	`NUMBER`	Unique identifier for the database.
`DBINC_KEY`	`NUMBER`	The primary key for the incarnation.
`DB_NAME`	`VARCHAR2(8)`	The `DB_NAME` for the database at the time of the `RESETLOGS`. The value is `UNKNOWN` if you have done at least one `RESETLOGS` before registering the target database with RMAN, because RMAN does not know the `DB_NAME` prior to the `RESETLOGS`.
`RESETLOGS_CHANGE#`	`NUMBER`	The SCN of the `RESETLOGS` operation that created this incarnation.
`RESETLOGS_TIME`	`DATE`	The time stamp of the `RESETLOGS` operation that created this incarnation.
`CURRENT_INCARNATION`	`VARCHAR2(8)`	`YES` if it is the current incarnation; `NO` if it is not.
`PARENT_DBINC_KEY`	`NUMBER`	The `DBINC_KEY` of the previous incarnation for this database. The value is `NULL` if it is the first incarnation recorded for the database.
`PRIOR_RESETLOGS_CHANGE#`	`NUMBER`	The SCN of the `RESETLOGS` operation that created the parent of this incarnation.
`PRIOR_RESETLOGS_TIME`	`DATE`	The time stamp of the `RESETLOGS` operation that created the parent of this incarnation.
