Data Guard :: Data Files Locations On Oracle 11gR2

Jun 15, 2012

I have set up a cross platform (Microsoft Windows IA (32-bit) -> Linux x86 64-bit) data guard and it worked fine.Then I did a switch over (which again worked) and found out the data is not getting replicated at all.. checked the data files available from the new primary database and found out they are in the windows format as below..

SQL> select name from v$datafile;

NAME
--------------------------------------------------------------------------------
D:ORACLEAPPADMINISTRATORORADATAMFSSYSTEM01.DBF
D:ORACLEAPPADMINISTRATORORADATAMFSSYSAUX01.DBF
D:ORACLEAPPADMINISTRATORORADATAMFSUNDOTBS01.DBF
D:ORACLEAPPADMINISTRATORORADATAMFSUSERS01.DBF
D:ORACLEAPPADMINISTRATORORADATAMFSRMANRMAN_TS01.DBF

and physically they were created at '/home/app/oracle/product/11.2.0/db_1/dbs/' and as

D:ORACLEAPPADMINISTRATORORADATAMFSREDO02.LOG
D:ORACLEAPPADMINISTRATORORADATAMFSREDO03.LOG

Data Guard :: Create Control File With Standby Keyword On Primary Database

Jul 4, 2012

What is difference when you issue a create controlfile with "standby" keyword on the primary database

ALTER DATABASE CREATE STANDBY CONTROLFILE AS '/path/db_stby.ctl';

vs. creating a control using

ALTER DATABASE BACKUP CONTROLFILE to '/path/db_control.ctl';

what does ORACLE put into the standby control that is "extra"? ie. what is the difference between a standby control file and a normal control file?

Backup & Recovery :: Changing Location Of Data And Temp Files From Auto-backup Of Control-file?

Jan 26, 2012

I have an oracle autoback of controlfile and spfile. I am trying to restore the production database using this backup, into a new server with a different directory structure.

I have completed the following steps in the restore process.

1. Creating a pfile from spfile

2. Changing the the location of cdump, udump, bdump and the control files ( there are three )

3. Then creating a spfile from this pfile

I am stuck on the next step where to rename all the datafiles and tempfile and restore the database. Following is what I did.

After mounting the database in RMAN, tried to run the following.

RMAN> run
2> {
3> allocate channel c1 device type disk
4> ;
5> @/home/oracle/rman_scripts/newloc.rman
6> SET NEWNAME FOR DATAFILE 1 TO '/u02/oradata/dorian/system01.dbf';
7> SET NEWNAME FOR DATAFILE 2 TO '/u02/oradata/dorian/undotbs01.dbf';
8> SET NEWNAME FOR DATAFILE 3 TO '/u02/oradata/dorian/sysaux01.dbf';
9> SET NEWNAME FOR DATAFILE 4 TO '/u02/oradata/dorian/users01.dbf';

[code]....

I am getting the following error message.

Starting restore at 25-JAN-2012 21:26:48
released channel: c1
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

Server Utilities :: How To Load If Data Is In Control File As Well As In Datafile

Apr 8, 2010

I am using perl script to dynamically generate the control file.If I have data in the control file as well as in the datafile, how would i write the control file in that case. Is the below one correct?

load data
INFILE '*'
INFILE '/export/home/test/test.csv'
INSERT INTO TABLE EMP fields
terminated by "," optionally enclosed by '"'
trailing nullcols
( empno, empname, sal, deptno )
[code]....

Is there any way that if my control file contains half of the data and my data file contains the other half of the data can i club this data into a logical record in the control file to populate the DB?

My exact 2nd requirement is, my DB contains 5 cols and for 1 col the data is common(countryName) which i have to pass to the control file dynamically and the .csv file contains the data for the other four cols. How could i combine these in the ctrl file and populate the DB?

so if the DB contains CountryName, empid, ename, sal and dept..I will get the CountryName to the ctrl file and csv contains the data for empid, ename, sal and dept. How would i combine these data into a logical record and populate the DB?

Data Guard :: Finding Unapplied Archived Log File In DR?

Sep 21, 2011

I wanted to make a script for applying the Archived log File in to DR by certain interval.

1) I will use the below view for finding the SEQUENCE so far applied.select sequence# from v$log_archive.
2) But how i can compare with the archive log files available in physical location with the above mentioned view.

eg:- the above view shows, the till the sequence 46789 is applied.And in the DR physical Location available sequences are 46795. which means 6 more archived log files are more, which are not applied into the DR so far.
