Moving ORACLE_HOME , Datafiles, controlfiles,redo log file locations

Version: 10.2.0.1.0
One of our test DB's software location(ORACLE_HOME) was wrongly installed in /home/oracle. We have been using this for an year now. Now we are thinking of moving the ORACLE_HOME to a new location /u02. Because of another disk maintenance activity, we have to move all datafiles , redo log files, control files, tempfiles to a different location as well.
This database is not in ARCHIVELOG mode(luckily).
If i do a fresh installation of 10.2.0.1.0 in /u02, i cannot use the old installation's system01.dbf, sysaux01.dbf,undotbs01.dbf files for this fresh installation. Right?
How do i go about doing this whole move thing?

This database is not in ARCHIVELOG mode(luckily).
Why?

No.
Issue ALTER DATABASE BACKUP CONTROLFILE TO TRACE. Then Shutdown the database. Copy all the files including the trace generated. Change the control_files parameter from init<SID>.ora file. Copy this to new home. Also tailor the backup trace file for change in location of logfiles,datafiles. Then
$export ORACLE_SID=<SID>
$sqlplus /nolog
SQL>conn sys as sysdba
password:<Enter>
SQL>startup nomount pfile=NEW_HOME/dbs/init<SID>.ora
SQL>@location_of_trace_file_generated/tracefilename.trc
Add temporary tablespace and make it default temporary tablespace for the database.
Your database will be up and running.
Regards.

Best RAID configuration for storing Datafiles and Redo log files

Database version:10gR2
OS version: Solaris
Whis is the best RAID level for storing Datafiles and Redo log files?

Oracle recommends SAME - Stripe And Mirror Everything.
In the RAC Starter Kit documentation, they specifically recommend not using RAID5 for things like voting disk and so on.
SAN vendors otoh claims that their RAID5 implementations are as fast as RAID10. They do have these massive memory caches...
But I would rather err on the safer side. I usually insist on RAID10 - and for those databases that I do not have a vested interest in (other than as a DBA), and owners, developers and management accept RAID5, I put the lead pipe away and do not insist on having it my way. :-)

How to change the redo log file location.... ?

I want all my redo log files to be created in \u10 instead of current /u01?
How to do it? NOARCHIVELOG mode database on Oracle 10g R2.
Thank you,
Smirh

Hi..
I want all my redo log files to be created in \u10 instead of current /u01?I think it should be /u10 :)...

DROP and recreate the database. It is a *new* database without any data.
Check what datafile locations and redo log file locations you specify when creating the new database. Check if you have permissions and enough disk space.

Moving the online redo log files to different location

We just installed few more drives into our sandbox system and I want to move the online redo log files for better performance. We've got the SAPARCH directory moved to a different location.
Does anyone know how/where I can change the parameters so redo log files are pointed at different drives? It's not in the init<SID>.ora file...
Regards,
Sumit

Hi Sumit,
The following link contains information about moving the redo logs:

If you have a cold backup (database shutdown properly) without the redo logs, change this :
CREATE CONTROLFILE REUSE DATABASE "XE" NORESETLOGS NOARCHIVELOGto
CREATE CONTROLFILE REUSE DATABASE "XE" RESETLOGS NOARCHIVELOGYou have to change the NORESETLOGS to RESETLOGS for Oracle to recreate the online redo logs.

Need to understand when redo log files content is wrote to datafiles

Hi all
I have a question about the time when redo log files are wrote to the datafiles
supposing that the database is in NOARCHIVELOG mode, and all redo log files are filled, the official oracle database documentation says that: *a filled redo log file is available
after the changes recorded in it have been written to the datafiles* witch mean that we just need to have all the redo log files filled to "*commit*" changes to the database
Thanks for help

The wording is poor and should be modified to something like:
<blockquote>
+"a filled online redo log file is available for re-use after all the data blocks that have been changed by change vectors recorded in the log file have been written to the data files"+
</blockquote>
Remember if a data block that is NOT an undo block has been changed by a transaction, then an UNDO block has been changed at the same time, and both change vectors will be in the redo log file. The redo log file cannot, therefore, be re-used until the data block and the associated UNDO block have been written to disc. The change to the data block can thus be rolled back (uncommitted changes can be written to data files) because the UNDO is also available on disc if needed.
If you find the manuals too fragmented to follow you may find that my book, Oracle Core, offers a narrative description that is easier to comprehend.

Changing names of datafiles, tempfiles and redo log files

DB version:10g Release 2
Can i use
ALTER DATABASE RENAME FILE ...command to rename datafiles, tempfiles and redo log files?

Please note that when you use this command, you are doing nothing to the actual files on the OS. You are simply changing the db's knowledge of them, as stored in the control file.

Current redo log file is lost

Hi All,
I got a scenario in which my current redo log file is lost:
Do I need to:
1)Clear log file group
(or)
2)I should perform incomplete recovery.
What are the steps I should follow to recover this current redo log file?
1)*If it is inactive* I can make use of
ALTER DATABASE CLEAR LOGFILE UNARCHIVED GROUP 2;
which will drop and recreate the log file.To recover from loss of an active online log group in NOARCHIVELOG mode:
If the media failure is temporary, then correct the problem so that the database can reuse the group when required.
Restore the database from a consistent, whole database backup (datafiles and control files) as described in "Restoring Datafiles Before Performing Incomplete Recovery". For example, enter:
% cp /disk2/backup/*.dbf $ORACLE_HOME/oradata/trgt/
Mount the database:
STARTUP MOUNT
Because online redo logs are not backed up, you cannot restore them with the datafiles and control files. In order to allow the database to reset the online redo logs, you must first mimic incomplete recovery:
RECOVER DATABASE UNTIL CANCEL
CANCEL
Open the database using the RESETLOGS option:
ALTER DATABASE OPEN RESETLOGS;
Shut down the database consistently. For example, enter:
SHUTDOWN IMMEDIATE
Make a whole database backup.
To recover from loss of an active online redo log group in ARCHIVELOG mode:
If the media failure is temporary, then correct the problem so that the database can reuse the group when required. If the media failure is not temporary, then use the following procedure.
Begin incomplete media recovery, recovering up through the log before the damaged log.
Ensure that the current name of the lost redo log can be used for a newly created file. If not, then rename the members of the damaged online redo log group to a new location. For example, enter:
ALTER DATABASE RENAME FILE "?/oradata/trgt/redo01.log" TO "/tmp/redo01.log";
ALTER DATABASE RENAME FILE "?/oradata/trgt/redo01.log" TO "/tmp/redo02.log";
Open the database using the RESETLOGS option:
ALTER DATABASE OPEN RESETLOGS;
My question is when the redo log file is current. What steps we should follow?
Best regards,
Rafi.

2)If it is active then I can make use of below steps:

Hi Asif,
This link I have seen by refering to previous post.I just have a slight doubt in mind.
1)Do I need to make use of statement:
Alter database clear unarchived log file group#;
(or)
Only if your group is current(or you are not able to drop it) and is not archived then you should use above query.
We should perform incomplete recovery for this.If we have to perform incomplete recovery what are the steps I should follow?
I doubt you should be performing incomplete recovery for this.
Eg:Let us say my group 1 is dropped it has only one member and it is in active state.How to recover database?Can I get the steps?
You would not be able to drop it if it is in active state, did you meant it is corrupted? If yes then you can use below query
Alter database clear [unarchived] LOGFILE GROUP #;>

Is it possible to use Archive Redo log file

Hi friends,
My database is runing in archive log mode.I had taken cold backup on Sunday but i am taking archive log file daily evening.
Wednesday my database crash that means i lost all control file,redo log file,datafile etc.
I have archived log file backup till Tuesday Night and other files like control file,datafile etc of Sunday .
1)Is it possible to recover database till tuesday if yes HOW to use archive log file.
(See SCN no of control file and datafiles is same ,if we use RECOVER DATABASE command oracle shows that media recovery is not requide.)
we don't have current control file we had lost in media crash.
null

Dear friend
In this scenario
you lost the contorl file
1>If you have old copy of Contorl file,
which has the current structure of the
database and all the archive files then
you can recover the database with
Ponint in time recovery (Using Backup Controlfile)

See Overview of Physical Database Structures

Restore in noarchivelog mode ( redo log files have been dropped )

1, A full backup taken using RMAN is available on disk.
2, The current control files were NOT damaged and do not need to be restored.
3, All data files are damaged .
4, The database is in NOARCHIVELOG mode.
I restore database :
1. RMAN> STARTUP MOUNT
2. RMAN> RESTORE DATABASE;
3. RMAN> recover database;
in this step , I got the information about needing redo log files ; but the redo log
files have been dropped , what should i do ?
else
I want to know there is the command 'recover database using backup control file'
in rman or not ?
Tks

Possibly loss of data (because information in online redo logs is lost):
recover database until cancel;
(cancel immediately)
alter database open resetlogs; (to build a new set of redo logs)
It's not necessary to use a backup controlfile here.

Online redo log files being removed physically

Grid Infra version: 11.2.0.4
RDBMS Version: 11.2.0.4
Although this is a RAC DB, this is not a RAC-specific question. Hence posting it here.
Few months back, I remember issuing a command similair to below (DROP LOGFILE GROUP ...) and the redo log files were still physically present in the diskgroup.
If I remember correctly, the file is not deleted physical so that we can use the REUSE functionality (ALTER DATABASE ADD LOGFILE MEMBER '+REDO/orcl/onlinelog/redo1b.log' reuse to group 11; ) ie. you can use the REUSE command to add the logfile of the same name which is physically present in OS Filesystem/Diksgroup to redo log group.
But today, after I issued the below command, I checked the diskgroup location from ASMCMD
SQL> alter database drop logfile group 31;
Database altered.
From ASMCMD, I can that the file has disappeared physically. Is this a new feature with 11.2.0.4 or am I missing something here ?
ASMCMD> ls +DATA/msblprd/onlinelog/group_31.548.833154995
ASMCMD-8002: entry 'group_31.548.833154995' does not exist in directory '+DATA/msblprd/onlinelog/'

Just to add to what Aman has said.
It is a bad practice not to let OMF decide the placement of Online redo logs because of this issue especially when you use ASM.
Executing rm command in Linux/Unix is easy but Dropping ASM aliases in the disk group can be a hassle.
This is documented.
"When a redo log member is dropped from the database, the operating system file is not deleted from disk. Rather, the control files of the associated database are updated to drop the member from the database structure. After dropping a redo log file, ensure that the drop completed successfully, and then use the appropriate operating system command to delete the dropped redo log file."
http://docs.oracle.com/cd/E11882_01/server.112/e25494/onlineredo.htm#ADMIN11324
BTW . You don't even need to set db_create_online_log_dest_n to enable OMF for ORLs.
SQL> show parameter log_dest
