`RESETLOGS_CHANGE#`	`NUMBER`	`NOT NULL`	Start SCN of the branch
`RESETLOGS_ID`	`NUMBER`	`NOT NULL`	Resetlogs identifier (a numerical form of the timestamp of the branch)
`SEQUENCE#`	`NUMBER`	`NOT NULL`	Sequence number of the archive log file
`FIRST_CHANGE#`	`NUMBER`	`NOT NULL`	System change number (SCN) of the current archive log
`NEXT_CHANGE#`	`NUMBER`		SCN of the next archive log
`FIRST_TIME`	`DATE`		Date of the current archive log
`NEXT_TIME`	`DATE`		Date of the next archive log
`FILE_NAME`	`VARCHAR2(513)`		Name of the archive log
`TIMESTAMP`	`DATE`		Time when the archive log was registered

`APPLIED`	`VARCHAR2(8)`		Indicates primarily whether a given foreign archived log has been applied fully by SQL Apply: `YES` - SQL Apply has fully applied the foreign archived log and no longer needs it `CURRENT` - SQL Apply is currently applying changes contained in the foreign archived log `NO` - SQL Apply has not started applying any changes contained in the foreign archived log `FETCHING` - SQL Apply encountered a corruption while reading redo records from this foreign archived log, and is currently using the automatic gap resolution to refetch a new copy of the log from the primary database `CORRUPT` - SQL Apply encountered a corruption while reading redo records from this foreign archived log, and refetching a new copy of the archived log did not resolve the problem. SQL Apply will not refetch a new copy of this archived log automatically, and will require user intervention to manually register a new copy of the foreign archived log.
`BLOCKS`	`NUMBER`		Number of blocks in the log
`BLOCK_SIZE`	`NUMBER`		Size of each block in the log
