ASM Direct file access (for creating standby database in Standard Edition)

Hi all,
Just really looking for any opinions, experience etc. that people may have about this.
My company are looking to set up a RAC system. They have also asked me to think about creating a standby database for disaster recovery. The first problem they give me here is that they only pay for Standard Edition of Oracle, therefore Dataguard is not an option.
I know that one can setup "manual" standby databases with Standard Edition, automating the shipping of archive logs with hand-written scripts etc. However, as the primary here is RAC, and will be using ASM on the shared storage, I'm not sure that this would be possible (and I'm even less sure that it would be desirable!). I say this because I don't know of a way to access (using only the O/S and/or Oracle) the database files stored in ASM, and even if there was a way, I can't imagine it being a good idea..
Anybody know of a way to tackle it, or care to contribute anything to this? As I say, my opinion is that even if it is possible to get to those files within ASM and hence manipulate them, I'd be worried that it wouldn't be such a good idea. But I'm willing to bet I'm not the first to have thought about it...
Regards,
Ados
Edit 1:
Sorry, I should state that in principal, the basic environment is:
Windows 2003 Server
Oracle 10g R2
I didn't state that originally though, as I'd be keen to hear from anyone who may have attempted this on any O/S and Oracle version.

Edit 2:
I also realise we could put the archive logs on the local nodes.. but to reinforce the point, I'm talking about having them on the shared storage where - in theory - the management is easier and more effective.
Edited by: Ados on 16-sep-2009 9:35

For anyone interested..
I guess it would be done using RMAN (in fact, I'm sure of it...) in which case, I feel a lot more comfortable doing it!!
For example:
backup as copy archivelog ALL to destination 'c:\temp\';
This way, it shouldn't matter if the arch logs are stored using ASM, we can now get them and "see" them.. and hence "manipulate" them (pass them on to a standby DB, for example).
I'm just waiting to get my hands on a Standard Edition installation where I can test all this.. To try it all out (with 2-node RAC, and a standby server) I don't think I'll get a chance, so still interested in opinions, or if anyone's actually done this.

Ados

The Critical Problems for Creating Standby Database

The Critical Problems for Creating Standby Database:(I want to create a physical standby database on the same system of the primary database)
1. Should I copy all the backup datafiles, standby controlfile and password file to a same directory before the first time to mount the standby database?
2. Before mounting the standby database, Should I change the datafile's name to a new one in the standby controlfile? How to change them?
3. When issuing the command to mount the standby database, should I specify the controlfile's name.(using which controlfile to mount)
These problems are not clearly secified in Oracle documentations.

Can you point us to the Windows specific documentation you refer to?
The parameter DB_FILE_NAME_CONVERT should take care of the new mapping for your datafiles (and LOG_FILE_NAME_CONVERT for logs), so you should be able to put them where you want and use the parameter to point Oracle to the correct location. You should not need to change the name in the controlfile.
Place your standby controlfiles where you have the control files defined in your parameter file and Oracle should recofgnise that it is a standby db. You should not need to specify which controlfiles to use (if this is even possible), your CONTROL_FILES init parameter points to them.
Not sure about the password file....my instances are on separate boxes and the password file has the same name on both primary and standby.

Regrading standby database in standard edition

hi gurus
i m facing problem in configuring standby database in standard edition windows 2008 .
os-windows 2008 standard
oracle 11gr2
i have copied files from primary n copied it to same location on standby...at that time database was in noarchivelog mode
then i made it archive n create standby controlfile...also i have created same service name thru oradim with mentioning pfile and same password as on primary
so it created pfile and password file...
i opened the database in nomount with pfile
then mount with standby controlfile it got mounted n the mode is automatically archivelog mode but as i didn't taken the same pfile of primary it didnt take the destinations as such n made archive in flash recovery area
now i m a bit confused how to apply archive..i copied some archive and placed it in flash rec area
i tried all options managed recovery.recover standby database,recover database until cancel
but all give error
please tell how i proceed..what shud b the right process in standby standard edition
if possible send me a good link for standby database creation in windows 2008 standard with how to ftp files with mget mput..
anyone if kindly provide a good link...wud b of great help
thanks all

on your standby database you can use:
set logsource path_to_archives
This will let Oracle know where the archive files are on the standby database.
Then you can apply the archives with:
recover standby database
Another option is to use Dbvisit Standby to automate the whole standby database (including creation) for you when you have Oracle Standard One or Oracle Standard Edition One.

Disable Direct File Access for owa

Hi
How can i exclude some users from disable Direct File Access on my OWA
Thanks
MCP MCSA MCSE MCT MCTS CCNA

No problem Yasser.
Once you have created a policy with the settings you require you can apply it to a user (or multiple users) by using either the ECP or using the shell:
In ECP there are 2 ways:
1. Select the mailbox (or mailboxes) then select "View Details" under "Email Connectivity". This will open a dialog allowing you to apply the relavant owa policy.
2. Edit the mailbox and navigate to "Mailbox Features". Then select "View Details" under "Email Connectivity". This will open a dialog allowing you to apply the relavant owa policy.
In Shell:
Set-CASMailbox -Identity <email address> -OwaMailboxPolicy:<owa policy name>
If you need to do multiple mailboxes using the shell you can pipe it through a Get-CASMailbox command.

Standby Database with Standard Edition

Hi All,
I'm attempting to setup a Standby database with Oracle 10g Standard Edition. I must manually copy over the archive logs to my Standby database server because i'm using Standard Edition.
Once my primary database archive logs have been copied over to the standby location shouldn't the database automatically apply those archive logs? I have issued the "alter database recover managed standby database disconnect from session" so my understanding is that it is in recovery mode and shoudl be finding the archive logs to apply. Can anyone confirm that this configuration should work with Standard Edition and perhaps point me in the right direction, which parameters in the init file to check, to get my standby database to apply these archive logs automatically.
Thanks,

To quickly determine the level of synchronization for the standby database, issue the following query on the physical standby database:
SQL> SELECT ARCHIVED_THREAD#, ARCHIVED_SEQ#, APPLIED_THREAD#, APPLIED_SEQ#
2> FROM V$ARCHIVE_DEST_STATUS;
ARCHIVED_THREAD# ARCHIVED_SEQ# APPLIED_THREAD# APPLIED_SEQ#
1 947 1 945

Archive apply issue for standby database in Standard Edition.

We have setup standby database in Oracle standard edition. the archive log cannot be send by oracle automatically. So we manually send the archive over. But do not see the database apply the archive log file. What could be wrong and where should we check on it?
We also used following when finishing the standby DB after running "recover standby database;" for a few archive log file:
alter database recover managed standby database disconnect from session;
======================================================================================
This is the status:
SQL> select OPEN_MODE, SWITCHOVER# ,REMOTE_ARCHIVE ,ARCHIVELOG_CHANGE#,SWITCHOVER_STATUS, DATABASE_ROLE from v$database;
OPEN_MODE SWITCHOVER# REMOTE_A ARCHIVELOG_CHANGE# SWITCHOVER_STATUS DATABASE_ROLE
MOUNTED 495550636 ENABLED 1.2201E+13 SESSIONS ACTIVE PHYSICAL STANDBY

The DB version is 10.2.0.5
I can do this to apply at standby DB:
SQL> set autorecovery on
SQL> recover standby database;
Then I tried to run this to leave the session:
alter database recover managed standby database disconnect from session;
Do not seen any apply.

Oracle manually standby database with standard edition

Hi, I want to have a plan for disaster. I'm triying with two virtual machines with oracle database 10g on suse linux. I follow these URLs
http://www.dbasupport.com/oracle/ora10g/manual_standby.shtml
http://oramdq.blogspot.com/2009/05/como-configurar-un-sistema-de-alta.html
and it look that work all right.
I know that with manually standby database we applied archived logs, and so, we don't propagate any physical changes to secondary database (standby), for example, if I create a new tablespace, or adding a new datafile to an existing tablespace, it don't work in the secondary database.
Anyone does know how is the better way to apply the physical changes??
Anyone have any scripts to do that?
Thanks in advance.

HI,
Add the STANDBY_FILE_MANAGEMENT = AUTO to the primary parameter file, it will solve it.

Physical standby database in Standard Edition.

Hi, we have Standard Edition and want to implement a stand by environment. Is it true that with this edition archive logs are not transported automatically to the stand by server using LOG_ARCHIVE_DEST = my_stdby_service ?
Also, let's suposse I managed to transport archive logs, do they get applied by stand by database automatically or with Standard Edition the only way we have is applying them manually?
Thanks and regards.

Hi
Ref to your SE Standby database, if you are still looking for an Automated Solution you can visit www.anbultechnologies.co.uk . In solutions you can find a product which provides fully automated Standby solution with Automatic failover. We have been using that solution for couple of years without any problems.
This solution is based on Oracle Standard Edition and provide functionaility similar to EE data guard.

Creating standby database

Hi
I want create standby database in Oracle 10g.
I can create standart database by using database configuration assistant.
How can I create standby database in Oracle 10g?

Hi,
Standby databases, in a nutshell, acts as a failover for our mission critical production databases. When production database crashes, applications can quickly switchover to the stand by databases.
What type of Standy you are willing to go for ??
Physical Standby Database
Standby database is called “physical” if the physical structure of stand by exactly matches with stand by structure. Archived redo log transferred from primary database will be directly applied to the stand by database.
Logical Standby Database
Stand by database is called “logical”, the physical structure of both
databases do not match and from the archived redo log we create SQL statements then these statements will be applied to stand by database.
Follow this link for creating standby database

Creating standby database using RMAN

When I'm creating standby database with RMAN command
'duplicate for standby' backups for creating standby database
have to be accessible from host where standby database
is created. I can copy the backups to standby host, or use
NFS to share the disk with backups to standby host.
But when I have backups in ASM diskgroup how can
I achieve it would be accessible from standby host?
Thanks a lot for advice,
M.

OK, thanks,
I will create standby using Grid, but I have the following problem:
database instance is running on the host where I want
to create standby database. The running instance is for
testing purposes and has the same db_name, db_unique_name, db_domain
parameters as in primary database.
I will change db_unique_name to be distinct from primary database one,
should I also change instance SID not to be the same in
testing database and standby on the same host, or when creating standby
database I can specify distinct one for standby database?

To create standby database using oracle 10g standared edition

my producation database is oracle 10G standard edition .Can i implement a oracle dataguard or standby database using standard edition licenses.if standby database is possiable in standard edition .what are the steps for creating a standby database using oracle 10g standard edition.

General answer is http://download.oracle.com/docs/cd/B19306_01/license.102/b14199/editions.htm#BABJICBB.
For Data Guard you cannot :
- use instance parameters to automatically send archived redo logs
- use instance parameters to resolve archived redo logs gaps
- create a logical standby
- use SQL statements to do switchover / failover
- use Data Guard Broker.

ORA-19505: failed to identify file - RMAN in creating standby DR database.

I got this error when creating standby database at remote target server.
ORA-19505: failed to identify file "/backup/dxp1p/online/DXP1P_CF_c-2027711285-20131204-01"
Here is what I did:
1.   started the listener and created corresponding tnsnames entry at remote standyb server
2. startup nomount to the standby database at remote server for an empty instance (instance name dxp1p).
3. All rman backups are in the /backup mount point at primary and the mount point is shared on the remote server as nfs.   So, whatever have in the backup we should be able to see and read from the remote as well.
4. Run the following at primary rman:
sql 'alter system archive log current';
backup current controlfile for standby;
sql 'alter system archive log current';
crosscheck backup;
crosscheck archivelog all;
exit
5.   Start the rman command from primary after connected to the standby server, as the primary DB uses ASM and the standby DB uses file system for the database files:

Creating Standby Database from ASM Databse none ASM

I have ASM RAC database running on Solaris 10. I want to take a backup with RMAN and move the Backup to none ASM on other Stand alone server. I want to use this none ASM backup database to create Standby Database for Test purpose. Is it doable? If it is doable can you answer following questions?
What command should I use with RMAN to take a full backup and move it to none ASM platform?
Thank you

Well, the answer is most likely yes, but first need to confirm
- Do you want a physical or logical standby?
- Will the standby run on the same platform , i.e. also Solaris 10?
- What version of database ? It is much easier in 11g.

Error while creating standby database for ebs prod database

Hi,
We are getting error while trying to create a standby database for EBS database by using RMAN DUPLICATE commands,
Steps followed:
1.) Backup the primary database (Ebs PROD db). This was done on 12-Mar-2012
***RMAN backups are scheduled to run @10:00 pm every night. Flash Recovery Area has been configured and backup is taken at this location
everyday.
2.) Tar the backupset, autobackup, archivelogs etc in FRA .... and copy this to the target server (STANDBY).
*** Copy(oracle rdbms binaries and FRA) completed @12:00AM on 14-Mar-2012
3.) Tried to create standby database by using RMAN duplicate on 14-Mar-2012
RMAN> rman sys/sys@PROD auxiliary /
RMAN> duplicate target database for standby dorecover nofilenamecheck;
After, some time the RMAN DUPLICATE process errors out with,
ORA-19563: header validation failed for file
We are not sure about the cause of this error. While searching in Metalink, we got several notes (ex, 352074.1) but all the causes stated for this error
are not applicable in our case. We double checked our instance to confirm this.
We have also found that in PROD database there are 65 datafiles and after the RMAN DUPLICATE errors out in the targer server (STANDBY) the RMAN managed to restore 51 datafiles before erroring out.
# Please note PROD database was also backed up on 13-Mar-2012. We have a suspicion that backup on 13-Mar may be a possible cause for this error but we are
not sure.
Need suggestions if there can be any other possible causes???
We are in a fix and it would be appreciable if we get some quick suggestions..
Regards,
Rupdipt
Edited by: orarup on Mar 14, 2012 12:29 AM

When opening the file to be placed in a copy or backup set, to be inspected, or used as the target for an incremental restore, its header was not recognized as a valid file header for a file of the indicated type (data file, archived log, or control file) belonging to the current database.
Kindly Ensure that the correct files are being specified for the copy or backup operation.
