V$CACHE_TRANSFER

This is an Oracle9i Real Application Clusters view. The V$CACHE_TRANSFER view is identical to the V$CACHE view but only displays blocks that have been pinged at least once. This view contains information from the block header of each block in the SGA of the current instance as related to particular database objects.

XNC	NUMBER	Number of PCM lock conversions due to contention with another instance. This column is obsolete but is retained for historical compatibility.
FORCED_READS	NUMBER	Number of times the block had to be reread from disk because another instance had forced it out of this instance's cache by requesting the PCM lock on the block in exclusive mode
FORCED_WRITES	NUMBER	Number of times DBWR had to write this block to disk because this instance had used the block and another instance had requested the lock on the block in a conflicting mode
NAME	VARCHAR2(30)	Name of the database object containing the block
PARTITION_NAME	VARCHAR2(30)	NULL for non-partitioned objects
KIND	VARCHAR2(15)	Type of database object See Also: Table 3-1
OWNER#	NUMBER	Owner number
GC_ELEMENT_ADDR	RAW(4)	The address of the lock element that contains the PCM lock that is covering the buffer. If more than one buffer has the same address, then these buffers are covered by the same PCM lock.
GC_ELEMENT_NAME	NUMBER	The name of the lock that contains the PCM lock that is covering the buffer
