Column	Datatype	Description

TIMESTAMP	DATE	Timestamp when the database change was made
COMMIT_TIMESTAMP	DATE	Timestamp when the transaction committed; only meaningful if theCOMMITTED_DATA_ONLYoption was chosen in aDBMS_LOGMNR.START_LOGMNR()invocation

RBABYTE	NUMBER	RBA byte offset within the block
UBAFIL	NUMBER	Undo Block Address (UBA) file number identifying the file containing the undo block
UBABLK	NUMBER	UBA block number for the undo block
UBAREC	NUMBER	UBA record index within the undo block
UBASQN	NUMBER	UBA undo block sequence number
ABS_FILE#	NUMBER	Data block absolute file number of the block changed by the transaction
REL_FILE#	NUMBER	Data block relative file number. The file number is relative to the tablespace of the object
DATA_BLK#	NUMBER	Data block number within the file
DATA_OBJ#	NUMBER	Data block object number identifying the object
DATA_OBJD#	NUMBER	Data block data object number identifying the object within the tablespace
SEG_OWNER	VARCHAR2(32)	Owner of the modified segment
SEG_NAME	VARCHAR2(256)	Name of the modified data segment
TABLE_NAME	VARCHAR2(32)	Name of the modified table (in case the redo pertains to a table modification)
SEG_TYPE	NUMBER	Type of the modified data segment. Possible values are: 0 = UNKNOWN 1 = INDEX 2 = TABLE 19 = TABLE PARTITION 20 = INDEX PARTITION 34 = TABLE SUBPARTITION All other values = UNSUPPORTED
SEG_TYPE_NAME	VARCHAR2(32)	Segment type name. Possible values are: UNKNOWN INDEX TABLE TABLE PARTITION UNSUPPORTED TABLE_SPACE
TABLE_SPACE	VARCHAR2(32)	Name of the tablespace containing the modified data segment. This column is not populated for rows where the value of theOPERATIONcolumn is DDL. This is because DDL may operate on more than one tablespace.
ROW_ID	VARCHAR2(18)	Row ID of the row modified by the change (only meaningful if the change pertains to a DML) This will be NULL if the redo record is not associated with a DML.
SESSION#	NUMBER	Session number of the session that made the change
SERIAL#	NUMBER	Serial number of the session that made the change
USERNAME	VARCHAR2(30)	Name of the user who executed the transaction
SESSION_INFO	VARCHAR2(4000)	Information about the database session that executed the transaction. Contains process information, machine name from which the user logged in etc. A possibleSESSION_INFOcolumn may contain the following: login_username = HR client_info = OS_username = jkundu Machine_name = nirvan OS_terminal = pts/31 OS_program_name = sqlplus@nirvan (TNS V1-V3)
TX_NAME	VARCHAR2(256)	Name of the transaction that made the change. This is only meaningful if the transaction is a named transaction.
ROLLBACK	NUMBER	1 = if the redo record was generated because of a partial or a full rollback of the associated transaction 0 = otherwise
OPERATION	VARCHAR2(32)	User level SQL operation that made the change. Possible values are: INSERT = change was caused by an insert statement UPDATE = change was caused by an update statement DELETE = change was caused by a delete statement DDL = change was caused by a DDL statement START = change was caused by the start of a transaction COMMIT = change was caused by the commit of a transaction ROLLBACK = change was caused by a full rollback of a transaction LOB_WRITE = change was caused by an invocation of DBMS_LOB.WRITE LOB_TRIM = change was caused by an invocation ofDBMS_LOB.TRIM LOB_ERASE = change was caused by an invocation ofDBMS_LOB.ERASE SELECT_FOR_UPDATE = operation was aSELECT FOR UPDATEstatement SEL_LOB_LOCATOR = operation was aSELECTstatement that returns a LOB locator MISSING_SCN = LogMiner encountered a gap in the redo records. This is most likely because not all redo logs were registered with LogMiner. INTERNAL = change was caused by internal operations initiated by the database UNSUPPORTED = change was caused by operations not currently supported by LogMiner (for example, changes made to tables with ADT columns)
OPERATION_CODE	NUMBER	Number of the operation code. Possible values are: 0 = INTERNAL 1 = INSERT 2 = DELETE 3 = UPDATE 5 = DDL 6 = START 7 = COMMIT 9 = SELECT_LOB_LOCATOR 10 = LOB_WRITE 11 = LOB_TRIM 25 = SELECT_FOR_UPDATE 28 = LOB_ERASE 34 = MISSING_SCN 36 = ROLLBACK 255 = UNSUPPORTED
SQL_REDO	VARCHAR2(4000)	Reconstructed SQL statement that is equivalent to the original SQL statement that made the change. Please refer toOracle Database Utilitiesbefore executing SQL_REDO to your database. LogMiner does not generate SQL redo for temporary tables. In such a case, this column will contain the string"/* No SQL_REDO for temporary tables */".
SQL_UNDO	VARCHAR2(4000)	Reconstructed SQL statement that can be used to undo the effect of the original statement that made the change. DDL statements have no corresponding SQL_UNDO. Please refer toOracle Database Utilitiesbefore executing SQL_UNDO to your database. LogMiner does not generate SQL undo for temporary tables. In such a case, this column will contain the string"/* No SQL_UNDO for temporary tables */".
RS_ID	VARCHAR2(32)	Record set ID. The tuple (RS_ID, SSN) together uniquely identifies a row inV$LOGMNR_CONTENTS. RS_ID uniquely identifies the redo record that generated the row.
SEQUENCE#	NUMBER	Sequence number of the redo log that contained the redo record corresponding to the database change
SSN	NUMBER	SQL sequence number. Used in conjunction with RS_ID, this uniquely identifies a row in theV$LOGMNR_CONTENTSview.
CSF	NUMBER	Continuation SQL flag. Possible values are: 0 = indicates SQL_REDO and SQL_UNDO is contained within the same row 1 = indicates that either SQL_REDO or SQL_UNDO is greater than 4000 bytes in size and is continued in the next row returned by the view
INFO	VARCHAR2(32)	Informational message about the row. For instance, the string "USER DDL" in INFO column indicates that the DDL statement returned in SQL_REDO column was the top-level DDL executed by the user and the string "INTERNAL DDL" in INFO column indicates that DDL statement returned in SQL_REDO column was executed internally by the RDBMS.
STATUS	NUMBER	0 indicates that the reconstructed SQL statements as shown in the SQL_REDO and SQL_UNDO columns are valid executable SQL statements. Otherwise, the reconstructed SQL statements are not executable. This may be due to the fact that no data dictionary was provided to LogMiner for the analysis, or that the data dictionary provided did not have the definition of the object being mined.
REDO_VALUE	NUMBER	Used as input to theDBMS_LOGMNR.MINE_VALUE()andDBMS_LOGMNR.COLUMN_PRESENT()functions
UNDO_VALUE	NUMBER	Used as input to theDBMS_LOGMNR.MINE_VALUE()andDBMS_LOGMNR.COLUMN_PRESENT()functions
SQL_COLUMN_TYPE	VARCHAR2(30)	This column is deprecated.
SQL_COLUMN_NAME	VARCHAR2(30)	This column is deprecated.
REDO_LENGTH	NUMBER	This column is deprecated.
REDO_OFFSET	NUMBER	This column is deprecated.
UNDO_LENGTH	NUMBER	This column is deprecated.
UNDO_OFFSET	NUMBER	This column is deprecated.
DATA_OBJV#	NUMBER	Version number of the table being modified
SAFE_RESUME_SCN	NUMBER	Reserved for future use
XID	RAW(8)	Raw representation of the transaction identifier
PXID	RAW(8)	Raw representation of the parent transaction identifier
AUDIT_SESSIONID	NUMBER	Audit session ID associated with the user session making the change
