How to validate a manual standby

Hi all,
I am setting up a manual physical standby and I want to periodically check the standby database for physical and logical corruption.
I am not sure what is the best way to do it:
1) should I only use dbv?
2) should I open the database read only and use RMAN "validate database check logical ;" ?
3) should I open the database read only and use anlter table ... validate structure cascade ; for every table?
4) Do steps 2 and 3 do the same checks?
Thanks,
Andrea

as always, Standby is image copy so if any logical corruption in primary you will have those in standby too..
May be due to some mount point issues (or) any other there is chance for physical corruption.
So either you can go for DBV, Even you can check by RMAN too.
Better, if you perform some tests like creating a user with tables(schema) & open standby and keep track the status. I think if you able to open and count is same. You are fine.
Another point , If any corruption in your database, MRP process will be died and no recovery will be performed, So until unless you able to perform Recover, then there is no issue at the most.+

How to Create Manual Standby for a Oracle 11g RAC with ASM to Single Instan

Hi All,
I have a task to configure a Single Instance Standby Database with ASM for 2-node Primary RAC+ASM database.
Version using : 11.1.0.6 Oracle 11g --- *" STANDARD EDITION "* Please note datagaurd will not be supported in standard edition.
Primary database - 2 -Node RAC using ASM storage (All datafiles, redologs, controfile and archive logs)
Need to setup a single instance standby database manually and than using scripts to transfer the archive logs from primary server to standby server to do recovery time to time.
Please let me know if there are any configuration document(s) which can help me to set the manual standby? or need your kind help to give your valuable ideas how to go in above situation.
Thanks in advance

Well if the archive logs are stored in ASM on the primary nodes, you almost definitely want to be using RMAN to access them. Then to transfer between primary and standby there are many options, this is essentially the step that Data Guard takes care of - so if you (and I) are running Standard Edition, this is the part to "worry" about.
I'm not really sure what you mean by this:
As in standard edition the archive destination will be on ASMI don't think the Edition of Oracle (Standard or Enterprise) dictates where and how you store your archive logs, but it's possible I've misunderstood what you mean...SE dictates that database storage for RAC will be ASM, including archive log files. Anything else is not officially supported. I haven't tested but it may be that you can use LOG_ARCHIVE_DUPLEX_DEST to specify a local filesystem for archive log files as well.
If that doesn't work you'll have to script rman "backup as copy" jobs regularly and then transport the results of that.

By the way, it seems Robert has been pretty helpful, it's polite to give him some points dude. And since this is your thread, not mine, give him a "helpful" from me too :p
El DBA
Incidentally if you are forced down the RMAN backup as copy route then this will likely throw your current backup retention strategy somewhat, you'll need to think carefully about when an archivelog can be deleted following backup, how many times it might be backed up and so on. I do understand, and have argued for, the use of SE RAC. I also understand and have argued for and implemented manually managed standby a number of times. However by the time your primary database is a RAC instance and you need a standby for DR etc then you really have to look very seriously at whether Standard Edition is still the right investment or not. You will be spending a lot of DBA time managing and troubleshooting this, and you will find that it is less reliable than the off the shelf solution. I suspect that you are very close to the point where an EE installation becomes a worthwhile investment here.

How to shift Manual Standby Database to Primary Database

Hi all,
My Database edition is Oracle 10G standard Edition and runing 24X7 and configure Manual Stand by Database. if I were changing some iniliazation parameter and datafiles.
What can I do ?
i) How to swift the Manual Stand by Database to Primary Database.
ii) What is the procedure by step by step information need.
Regards.....

If you're using a Manual Standby Database I assume you are using a pfile to apply the archived logs transported from the primary database created while creating the Manual Standard. at that time you should have kept the spfile in place too.
If you have done this, then you can simply open an SQL*Plus session connect as sysdba and issue a simple STARTUP command.
This will use the SPFILE by default and your database will be opened normally.
But if you don't have an SPFILE you can always create one, just specify the necessary control files (not the standby control file) in your pfile, remove unwanted parameters and create the spfile, and use the same step as above and issue a STARTUP.
But once you open your standby database normally you will not be able to switch back to standby mode, you have to recreate it again from a cold backup and create a new standby control file.

How to validate material status in physical Inv Doc creation using MI01

Hi Experts,
I would like to know how to validate material status while creating physical inventory document using MI01 transaction.
I tried to figure out a suitable BADI and customer exits ,but it didnt work out well.
Kindly share your thoughts on how this can be achieved.
Regards,
Mohammed Aslam Rasheed

Do you really create your inventory documents with this MI01 transaction manually by entering material for material?
The real transaction for physical inventory is MI31. How do you want SAP to react if hundreds of materials are selected and inventory documents are created in a batch process?
SAP takes care about the material status in MI04 and MI07 transactions.
I am not aware of any exit for MI01 maintenance, you may consider Explicit and Implicit Enhancement Options

Manual Standby on Standard Edition

Hey, I try to setup a manual standby on standard edition 10gR2.
Source is a RAC database (standard edition on sles10 sp3)
I created a node and created a oracle instance on this node. This node is using the filesystem for the oracle files.
I did a hotbackup of the source database and copied all files over to the other host.
Which parameters needs to be change in the init.ora and how can I recover my database ?
Articles like
http://www.databasejournal.com/features/oracle/article.php/3682421/Manual-Standby-Database-under-Oracle-Standard-Edition.htm
or

Thanks for your patience... :-)

Manual Standby and Archlogs application

Hi There,
I need to set up a manual standby database for one of our production databases. We are using oracle 11g (11.1.0.7) 64x STANDARD EDITION on Windows 2008 server 64x.
I shutdown the database, copied the data files and redo logs to a new server (same directories structure to the production database); I created a standby controlfile and a pfile and copied both across to the new host.
I created the oracle windows service on the new machine and started the database as follows:

Database altered.The production database has forced logging enabled in it so that we can capture all the DDL statemtents.
We created a dummy schema, a dummy table (with few rows); issued a commit, and then switched the logs few times to create the necessary archive logs. We then manually moved the archive logs to the new standby host, and put them under the appropriate directory (D:\oracle\flash_recovery_area\STDBT\ARCHIVELOG\2010_04_13).
Now we tried to recover the database by applying the new shipped logs:

Media recovery cancelled.So, the issue here is that even though the archive logs did exist in the correct directory, when we hit enter to accept the default, oracle didn't find the logs and it was looking for a file with the format "O1_MF_1_46_%U_.ARC" instead of "O1_MF_1_46_5W9W3LT3_.ARC" and so the recovery failed.. How can we fix this so that oracle will detect the correct archlog name so that when we automate the applying of the logs it will work (and we don't have to do enter them manually one by one)?

Single-instance manual standby for a three-node RAC database

Hi all,
I am wondering how it is possible to create a manual standby database for a rac primary database.
Oracle versione is standard edition 11.1.
I have experience creating and managing manual standby for single-instance database; I am wondering if and how I can instruct the single-instance standby database to discover and apply the three redo threads that I will copy from the primary site to the standby site.
Should I use rman to catalog all the archived log on the standby site ?
Should I configure many LOG_ARCHIVE_DEST_n parameters to point to many different path, one for each primary instance (i.e. one for each redo thread), and let rman automagically discover all the archived logs ?
Should I configure only LOG_ARCHIVE_DEST_1 , put archivelogs from all threads in the same folder, and let rman automagically discover all the archived logs ?
Thanks for every answer!
Andrea

Hi,
indeed i catalog all transfered archive logs in front of the recover process.
During the tests i believe (iirc) i was unable to recover from transfered archivelogs without catalog them first. But this statement is out of my mind, i am not 100% sure for this, sorry.
Some more details.
Because it is a standard edition, i have to use on the RAC side ASM. So our normal scripts to transfer archivelogs from primary to standby are obsolete.
So i decided to put the whole standby thing into the database. Now the primary database uses external scheduler jobs to do the work. The standby side is not using ASM, so there is no need to handle the logs in any special way.
The steps are:
1. Get SCN from primary and standby
2. Transfer the logs for the gap from ASM to "normal" filesystem.
3. Transfer (and compress, if not in LAN) to standby archive dest
4. Catalog on standby side
5. Recover on standby side
6. Delete on normal filesystem (on both sides, but on standby with a delay of 2 days just to be sure)
The steps on the standby side are both using the primary scn from step 1 as a parameter to avoid error messages during the catalog or recover call.

How to validate date picker value

Hi,
When a date is entered manually in the date picker .ie 01/03/08 the year 08 is saved as 0008 in the database rather than 2008. How to validate the value in date picker to save the year as 2008 instead of 0008.
Ven

The date picker does not always "store" the value for you - you create it with a particular format such as DD-MON-YY and then like any character to date field you need to be careful to use a format mask and to_date. Alternatively, change the format to DD-MON-YYYY.
Are you using this in a query or defined as a page item? Do you have the app on the APEX site?

Switchover of a manual standby database (no data guard)

Hi all,
I have a standby database .
I am using Oracle Standard Edition 10.2.0.4 / 10.2.0.5 so I have build a manual standby .
I am able to do a failover in the case something goes wrong; I was thinking if it is possible to do a manual switchover . and failback.
Do you thick that mounting the primary database and applying ALL archivelogs and online redolog to the standby database is enough ?
Do you think this is a supported operation?
How can I check the current scn of a mounted database? (v$database.current_scn shows 0 until the database is opened )
thnk you for every answer
Andrea

helter_skelter wrote:
hi,
You can see current_scn of standby database in v$database.current_scn. It is null only on primary database if it's in mount state.that's the problem: I am unable to mount both database and to check they have the same current_scn
not all changes are written to ARL so you can't recover standby database to exact the same SCN as primaryI thinks this is because the last changes are only recorder in online redolog, so I was thinking that a possible way to simulate a clean switchover could be as follow:
1 - shutdown immediate the primary database on server prod1
2 - shutdown abort the (manual) standby database on server dr2
3 - copy archivelog, controlfiles, tempfiles, onlinelogs from primary to the standby database
3 - copy controlfiles from standby database to primary database
4 - open the database on server dr2. It should open "read write" cleanly (mount + recover from archivelog + recover from onlinelog + open noresetlogs )
5 - mount the database on server prod1. It should mount as a physical standby database.
What do you think about it?
thanks,

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.

Manual Standby Recovery

Hi Friendz,
Oracle Db 9i
I have configured a manual standby database(I am not using Dataguard or "create standby database" command ) I only copy the cold backup to the target recovery server. I have been applying archive logs to it for a week now. I use the "recover automatic database using backup controlfile" command.
My problem is, when I try to "alter database open resetlogs" so I can test if I can open it, It is asking for the next archive log and message "that the system01.dbf needs recovery". How can I open my standby database and force it to stop recovery?
Thanks a lot
Ms Inday

How to add datafile to standby database

Hi,
We have standby database on another site and we are using manual recovery. How to add datafile to standby database after datafile is added to primary database.
We are on Oracle 9i R2.
Please help.
Thanks in advance

Hi,
When you recover the standby database after you added a datafile to the production, you will get an error that the file that needs recovery does not exist.
At this point you can connect to the standby and issue:
alter database create datafile '<original_name>' as '<new_name>';the new name is optional if the location of the files are the same.
After that, you can continue recovering the standby database.

How to validate inserted xml data in oracle is correct or not

(i.e.how to validate xml syntax and tags are correct)
XML data has been inserted in Oracle database.Once inserted
I want to validate that data entered and tags inserted are correct
or not.
Pl help

Some small remarks after a life time of write that small notepad.
Don't use XMLIsValid() - Apperently it was once ment for use in table constraints only AND the most annoying part, it doesn't give you a proper error message.
More usable is schemaValidate() - it throws a useful error message... I never came around to update that post or write a proper one while using schemaValidate().
I would be against advising / using a Java wrapper to achieve this goal unless you are on a pre 9.2 database version. Registering, validation and such is optimized (in memory) in Oracle from the beginning in 9.2.0.3 and onwards to avoid for instance reparsing of the XML Schema itself. If a XML Schema is registered a lot is optimized including DOM, which will be avoided and "outsmarted" by using XOB objects (see the Oracle manuals only a few hits and those will point you directly to the optimizations at hand).
