View 2 Replies View RelatedI am trying to create a new controlfile. I used "alter database backup controlfile to trace;" and then I copied and pasted the contents of the trace file into the .sql file. My sql script is
CREATE CONTROLFILE SET DATABASE "FIVESTAR" RESETLOGS NOARCHIVELOG
MAXLOGFILES 16
MAXLOGMEMBERS 3
MAXDATAFILES 100
MAXINSTANCES 8
MAXLOGHISTORY 292
[code]....
Actually, the name of my database was 'STAR' and I changed it to "FIVESTAR" int this .sql script. Now when I run this script with SQL> @ <path of my sql script>, it gives me the following errors:
ERROR at line 1:
ORA-01503: CREATE CONTROLFILE failed
ORA-01504: database name 'FIVESTAR' does not match parameter db_name 'STAR'
I can not run the control file treace file,why?
[oracle@hxl oradata_bak]$ more run_sql.sql

I was doing some R&D on my test machine trying to understand how controlfile works. I started up my db and then deleted (renamed)the controlfiles at OS level. I was expecting the db to shutdown. But it dint. Moreover when i queried select name from v$controlfile; it was still reflecting the old controlfile names. To check if it was still functioning, i created a new tablespace with one file and it also got created without any error.
What i dint understand is how could the db still be running when the control file was'nt there and new tablespace and datafile get created? As i understand, whenever a new file is created, an entry is made in the control file. But when control file dint exist where was the data about new tablespace and datafile written?
I am not able to create control file from scrip . it showing following error
ORA-01081: cannot start already-running ORACLE - shut it down first
CHARACTER SET WE8ISO8859P1

what's the difference between checkpoint_change# and controlfile_change#.
what's the checkpoint_change# use for ? does it use for recover ?
what's the controlfile_change# use for ?
when the controlfile_change# will be increase ?
SQL> select controlfile_sequence# from v$database;
CONTROLFILE_SEQUENCE#

Qs.) what is controlfile_sequence# ?
What's the maximum size of the control file in one database ?
i calculated it according to the following steps:
SQL>SELECT (BLOCK_SIZE/1024/1024)*20000 MB FROM V$CONTROLFILE WHERE ROWNUM = 1;
MB
------
312.5
The maximum number of the data block in one control file is 20000.
1)How a single control file is enough to have all the transaction's SCN no for older transactions.
Eg - A transaction has the SCN 01 and after a month the new transaction's SCN is 502. Is the control file holding all those (01 to 502) SCN in it or just will have the latest SCN no (ie - 502).

How can I clean dba_table? I suppose that that's happened because the user tablespace was full when he tried to create this table...
i found a temporary tablespace was corrupted,what happens to the database level, how to recover that tablespace? If need any recovery?

I am trying to have sqlldr running against a file:

Is it possible I get SQL*Loader-500: Unable to open file and 503 file not found just because the file name does not have an extension?
I can see that any file name I try it looks after whateverFileName.dat! Is there a way to have sqlldr working with files that do not have extensions?
How one should know whether RMAN is using target database control file or using separate catalog database. Also what one should do if he dont have catalog users credentials.

View 2 Replies View RelatedI am storing customer's snaps in a table ( column's data type as LONG RAW) using oracle forms Webutil. Now there are 250 snaps in the table. The file type of these snaps is JPG with the average size 30KB.
I made a backup using export utility before storing these snaps and the exported DMP file's size was 36MB. Now after storing these just 250 snaps of 30KB the DMP file's size is gone over 300MB.
i need to change column's datatype? or some where in oracle forms's image item. Because on window's file system the size of these files is just 8MB.

2 days ago i rename this file QXYZ_DATA01.dbf from it's original name of QXYZ01.dbf without knowing that I was in the 'abcd' instance. When I backup a controlfile I noticed that it was part of the 'abcd' data files, so I just delete it (from OS level).
Is there any risk involved in the 'abcd' instance? How do I get rid of that file 'qxyz_data01.dbf' in the 'abcd' instance.
How can we add another control file to DBOG database? I need to clarify all the steps during this process.

I am trying to get a readable version of a .trc file generated by Oracle
10.2.0.4.0 with tkprof, but I still have been unable to get this done...and this is what I have already tried:
tkprof /u00/app/oracle/admin/DB/udump/*BITN1234.trc /batch/salidas/student/BITNTRACE.txt
And whether I run this from my PL/SQL process (PRO*C) or from a command line, it returns:

could not open trace file /u00/app/oracle/admin/DB/udump/BITN1234.trc
I have already (from my PRO*C code and from command line)...
- made sure that the file is in the directory.
- run this from the udump directory, where the .trc file is...didn't work.
- run this from the udump directory, and specifying explicitely the
complete path anyway in the tkprof line (redundant...I know)...didn't work.
- tried to copy the file to another directory in order to run the tkprof,
and it returns:
cp: BITN1234.trc: The file access permissions do not allow the specified
action.
- tried changing privileges with:
chmod a+r BITN1234.trc
and it returns:
chmod: BITN1234.trc: Operation not permitted.
- tried to run tkprof01 instead of tkprof and it returns:

I mean to ask you Multiplexing of the data file or control file is required. Or any best possible way to configure Physical file structure.
