We are having 10gR2 DR setup,
We are planning for the cold backup of primary database on every sunday,
Does it going to affect DR sync if primary database is not availabe at the time of cold backup.
Difference between cold backup and cold cloning?
View 2 Replies View RelatedI have an oracle 8i recovery scenario. I have database cold backups of MONDAY and WEDNESDAY evenings. backup contains control files, data files, redo files
Database runs in Archive log mode and all archives of the month are available. Hard disk crashed on SATURDAY
all archive logs are still available at different location. Control files are not backed up to trace or file name or automatically means no backup control file (except ones in cold backups described above)
restoring all files from cold backup of either MONDAY or WEDNESDAY (I recovered to Wednesday) leaves nothing to recover. Querying V$RECOVER_FILE returns nothing. All log sequences higher to the number nnn displayed as result of ARCHIVE LOG LIST are present at correct location in correct format
My question is how do i ROLL Forward the Database from WEDNESDAY to SATURDAY in the above scenario.
I've got a database I need to restore from a cold backup, but I don't have a copy of the multiplexed members of the redo groups - each group has 2 members, and we've only got a backup of the first.
I know this won't stop the database from starting, and I can recreate them, but for ease can you copy and rename a redo log file from a multiplexed copy to correct location like you can with a control file?
we have scheduled cold backup for our database. is there any solution to resolve below mentioned errors other than RMAN hot backup or shutdown abort ?

Does the full cold backup of rman include online redologs?
So that at the time of recovery when i restore the database the online redologs also restored to that point?
platform: linux64 + glassfish I run msync as a client on the same server, but on the mobile manager web page, only download sync publications history can be found. What shall I do to sync local Berkeley database content to oracle?Do I need to create upload sync publications? Do I need to use mobile server workbench to create new applications?
View 1 Replies View RelatedThere is schedule cold backup was not taken successfully due to some DBF files are skipped and it would not copied to destination location? destination location is same server itself not for another remote server.
Total - 35 DBF files,
skipped - 4 DBF files
what could be issues? what are the points should be troubleshooting?
oracle 10.2.1 under windows 7 , today my friend format the server , but he have backup cold backup actually he take backup for all c:\ drive and i found that there is a oradata dir in this backup , so now i install new operating system win 7 and then i will create a database with the same name and then should i do a NID and restore the backup (cold)
how to do that ? i mean if i have database 10g under windows and this o.s is formatted we have backup of all c:\ drive which contain all oradata dir ? how can i restore this database
the database size is 3GB and contain the same default tablespace system,sysaux,undo,temp,users?
URL....I'm practicing for the OCP test and one of the questions is that there is a backup from yesterday and the last archived logs are from the day before yesterday not mentioned if it's cold or hot backup.
If its a cold backup - cant we recover it? is it a must to have the archived redo logs also when recovering a cold backup? That sounds not logical since those logs are made only for a hot backup. URL.....
I am trying to perform cold cloning at my home pc. when i am trying to create control file , i got this error.

My scenario is: database is in archivelog mode.
I run DLY cold backups including controlfile & archivelogs and keep 3 gens of backups and archivelogs to 3 days also. What is the correct procedure to restore back to an old cold backup. Database is backed up Mon,Tue,Wed on Thur we require to bring database back to Tuesday DLY security.
I have tried:
startup mount
restore database from tag 'DLYTUE'
recover database
( this just rolls forward on all archive logs once it restores datafiles, not getting to point to alter database open resetlogs.)
Next tried to :
recover database archivelog tag 'DLYTUE'
( same outcome )
What is the correct rman procedure including should I remove old archive logs from working OS directory ? Also need to know once I restore back and open database to TUE security how do you tidy up the archive logs and dumps which are no longer require i.e. : weds..
I have read about using the set until time option but how to I get absolute time from when cold backup completed if this is the correct procedure.
i have my oracle 10g database on my windows 7 and i install sql server 2005 on my windows server 2003 .now i want to sync my oracle 10g database with my sql 2005 means whenever i make any changes in my oracle table its automatically effect in my sql server also.

I have a Production database that is in archivelog mode and a Standby DR server. Both servers (Prod, Standby) have exact same structure and db name/version.
We manually scp archive logs and recover them to a manual standby database via SQL Scripts "cron". (I.E. set autorecovery on; recover standby database;)
We recently got out of sync with our log files and have not been applying them to the standby. As part of Prod Maintenance, these log files were deleted and are not available anymore.
I've tried several ways to "rebuild" our standby database. I have tried to Shutdown prod, backup all the db files and scp them to standby, re-create standby controlfile and startup mount and recover standby. Every time I try to apply a new archive log via recover standby, these are the errors:

When I check v$log_history, the new logs have not been applied. I've also tried the "Restore from incremental backup via SCN" method with same results. Is there a way to re-create the standby clean and ensure that the log chain that is currently broken gets fixed or reset? I would eventually like to get DataGuard in here, but that's not the case at the moment.
We are exporting from a 9i db to an 11g. During the migration, we are changing our character set from USASCII7 to AL32UTF8 so that the "extended" characters that our users like to put in text fields are stored and retrieved properly.
However, we've found a problem, and i'm not sure if Oracle has a method of dealing with. Searching this site and Oracle docs got me nowhere.
We store account #'s and credit card info in the DB encrypted with the dbms_obsfucation_tookit. We have an encryption key cross reference table that we use to store the key to un encrypt the data.
However, what we've found is that by importing these keys into our new character set database, the keys are no longer valid and can't be used with the DES3DECRYPT function to get the correct numbers out.
Is there a conversion utility or any tool that Oracle provides to maintain the encrypted datas "decrypt ability"? Worse comes to worse, we will have to write a script/procedure to decrypt everything on the 9i, import it to 11g, and then re-encrypt it.
Actually, i found that some forms if they are changed (like some buttons/text fields/code added to them) and this change can be saved and there is no errors in compilation. but when this form is run from the application, the change is not visible.
Even if the form with the image is removed from the directory, it still runs from the application link. Is there some memory issue or anything else.
I had a few regions on my page, the 2nd did not start a new row so it appeared horizontally where possible.During some experimentation, I created a new region with a sequence in between that started new row, but even when that region was conditionally never, my original 2nd region started on new row.
Original:
Region 1 - Region 2(empty) - Region 3 (new row/col no)>
New region added:
Region 1Region 1.5 (added, new row)
Region 2
Region 3>
Region 1.5 not shown:
Region 1Region 2
Region 3>
Let me know if you would like a test case for better visualisation.
If flashback is enable in physical standby database 1. If we failover at 11AM can I flash back NEW primary database to 6 AM ? 2. if I convert physically standby database to snapshot standby database at 11AM , Can I flashback snapshot standby database to 6 AM and do some works on it (DML operations) then converting the snapshot standby database into physical standby database ?

View 8 Replies View RelatedHere we have a data guard environment with db1(db_unique_name) as primary and db2(db_unique_name) as physical standby database. Also we configured one schema on a third machine as catalog database using following steps. The steps executed in catalog database(appsdb):

Now I want to restore this backup to some other system with new database. How to do this recovery to some other database on new system.
I am working for an agency which needs to synchronize(bi-directional) a master-master database configuration (Oracle <-> DB2) between sites hosted in Washington ,DC and Europe.
We are doing high level estimates right now of in-house development , Oracle Golden Gate and DBMOTO, MQ...etc with bi-directional synchronization with Oracle and DB2 in decentralized geographic locations?
Or production level experience(perf. issues, maintenance ..drawbacks) with any of the products mentioned.
When a user session commit he is waiting on 'log file sync' untill LGWR sends the message back to user session after writing log buffer content into redo log file.As far as i understand this is serialize operation(one at a time).
So how come i have 7 ms average 'log file sync' wait time and i can still perform 200 commits per sec ?
7 ms * 200 waits = 1400ms = 1.4 sec
we are getting below error on alert log file in logical standby database from May 2013 how can find time of sequence creation and how can restore these sequence redo files and sysnc databases primary and standby

I'm trying to work out how to synchronize a source and target database in an Oracle CDC implementation. We're in the architecture design stage of a near-real-time Operational Data Store style solution. Both the ODS and our pilot source system will be Oracle 10g. Our plan is to use Oracle Asynch Hotlog Change Data Capture to capture change data in near-real-time so that it can be applied to the ODS.
I understand the CDC apply process once the ODS and Source System are synchronized: DBMS_CDC_SUBSCRIBE.EXTEND_WINDOW to release the next window of change data, select from the publish views, then DBMS_CDC_SUBSCRIBE.PURGE_WINDOW to register the change data is no longer required.
But how do we do the initial synchronization if the source system is live and contains data and the ODS is new (and empty)? The easiest way would be to somehow flag EVERY row as change data. eg. Truncate every table and import. This would not be so good for existing CDC subscribers.
A more logical way would be to:
- Take a hot backup of the live prod database
- Activate CDC (DBMS_CDC_SUBSCRIBE.ACTIVATE_SUBSCRIPTION) on the source system to start tracking changes
- Manually build the ODS from the snapshot
- Start applying changes from CDC
if the source system is live, how can we GUARANTEE that the first 2 steps (snapshot and ACTIVATE_SUBSCRIPTION) are performed at EXACTLY the same time (ie. same SCN)?
If one of the redolog member corrupted and overcome this problem, I had removed the corrupted redolog member. Later I had added a new member to this group.
I would like to know, is the newly added log member will get sync with existing log member? How the newly added log member get sync with existing log member?

a) Old Retailer database
b) New Retailer Database
We cant delete old database but we are using and we want to use both of them.
Now problem
Both dbs have a table called retailer.
I want to prevent duplication in them.
I.e it there is a retailer 12 created in old one new one shldnt allowo us to create retailer
id---12
similarly if there is a retailer 13 in new one it shouldnt be created in old table
retailer ids are unique. its not the case that with retailer id for example 5 there is a
different retailer in these two tables of diffferent DBS. Its unique
Now I have to put this criteria
how can i do it?
Second questions===================
if a primary key is auto increment. how can i skip some numbers lets say it is 1,2,3,4
i want that when next record shld be inserted it shld be 6 not 5. i dont want to feed the value 6. i want to know how to change indexing of primary key to skip some numbers when its set to auto increments.
I was using physical standby but my primary database had had some HW issue.So I had activated standby database to handle production.During 3 months, standby database was our live database and our old primary was unavailable.Now HW issue on primary has been fixed.And I want to set again my old configuration : means set primary and standby db.
I'm trying this :
1) check the SCN on old primary
2) Rman incremantal backup from scn
3) on primary db : catalog
4) on primary db : recover database noredo
