ORA-01516
Thank you for visiting Spatial DBA - Oracle and ArcSDE.
Please visit Oracle DBA Tips (http://www.oracledbatips.com) for more Oracle DBA Tips.
====================================================================
ORA-01516: nonexistent log file, datafile, or tempfile "string" |
Cause: An attempt was made to use ALTER DATABASE to rename a log file, datafile, or tempfile; or to change attributes of a datafile or tempfile (e.g., resize, autoextend, online/offline, etc.); or to re-create a datafile. The attempt failed because the specified file is not known to the database 's control file or is not of a type supported by the request. |
Action: Specify the name or number of an existing file of the correct type, as appropriate. Check the relevant V$ table for a list of possible files. |
alert.log: Thu Jan 22 07:14:33 2009 alter database datafile '/u01/oracle_data/mydb/temp01.dbf' resize 1000M Thu Jan 22 07:14:33 2009 ORA-1516 signalled during: alter database datafile '/u01/oracle_data/mydb/temp01.dbf' resize 1000M ... |
Solution: Use correct syntax: SQL>alter database tempfile '/u01/oracle_data/mydb/temp01.dbf ' resize 100M; |

V$DELETED_OBJECT
V$DELETED_OBJECT displays information about deleted archived logs, datafile copies and backup pieces from the control file. The only purpose of this view is to optimize the recovery catalog resync operation. When an archived log, datafile copy, or backup piece is deleted, the corresponding record is marked deleted.
Column | Datatype | Description |
RECID | NUMBER | Deleted object record ID |
STAMP | NUMBER | Deleted object record stamp |
TYPE | VARCHAR2(26) | Identifies the type of deleted object:
|
OBJECT_RECID | NUMBER | Record ID of the deleted object |
OBJECT_STAMP | NUMBER | Record timestamp of the deleted object |
OBJECT_DATA | NUMBER | Displays additional internal information related to this deleted object. For internal Oracle use only. |
SET_STAMP | NUMBER | Set stamp of the deleted object |
SET_COUNT | NUMBER | Set count of the deleted object |
Note:
1. There is a bug in 10.2.0.4 and 11.1.0.6 that RMAN resync takes long time when v$deleted_object contains too many rows. The bug will be resolved in 10.2.0.5 (server patch set), 11.1.0.7 (server patch set) and 11.2.

V$DBFILE
V$DBFILE displays all datafiles making up the database. This view is retained for historical compatibility. Use of V$DATAFILE is recommended instead.
Column | Datatype | Description |
FILE# | NUMBER | File identifier |
NAME | VARCHAR2(513) | Name of the file |
Note:
SQL> select * from V$DBFILE; FILE# NAME ---------- ------------------------------------------------------------ 1 /u02/oracle_data/mydb/system01.dbf 2 /u02/oracle_data/mydb/undotbs01.dbf 3 /u02/oracle_data/mydb/undotbs02.dbf 4 /u02/oracle_data/mydb/cwmlite01.dbf 5 /u02/oracle_data/mydb/drsys01.dbf 6 /u02/oracle_data/mydb/odm01.dbf 7 /u02/oracle_data/mydb/tools01.dbf 8 /u02/oracle_data/mydb/users01.dbf 9 /u02/oracle_data/mydb/xdb01.dbf 10 /u02/oracle_data/mydb/prod_anal01.dbf 11 /u02/oracle_data/mydb/atlas01.dbf |

V$OBSOLETE_PARAMETER
V$OBSOLETE_PARAMETER displays information about obsolete initialization parameters. If any row of the view contains TRUE in the ISSPECIFIED column, then you should examine why.
Column | Datatype | Description |
NAME | VARCHAR2(64) | Name of the parameter |
ISSPECIFIED | VARCHAR2(5) | Indicates whether the parameter was specified in the parameter file (TRUE) or not (FALSE) |
Note:
1. Obsolete parameters in Oracle 10gR2:

2. ORA-32004 is usually related obsolete and/or deprecated parameters when attempting to start a database: ORA-32004: obsolete and/or deprecated parameter(s) specified. The parameter initialization file should be checked to see that none of the specified parameters match a parameter name stored in the V$OBSOLETE_PARAMETER view of that same database.
