I have a query regarding the cloning of a database.
Actually, i have made the two machine on a single system(Laptop) and now i want to clone the database, so for that i am unable to move the database backup from one Machine to another.
how can i move the backup and which command is applicable for that.
Note: - Listener/TNS is already configured on both the database.
I tried to clone a 2 node rac database to single instance non rac database using existing backup. I have not used connectivity to target or catalog. rman duplicate finished with below messages:
rman auxiliary sys/******@dbracdup
RMAN> duplicate database to dbrac spfile backup location '/oracle/backup';
...
...
Finished recover at 25-JUL-12
Segmentation fault
And the database was in mount stage, and when i tried to open database it failed with below error:
SQL> alter database open;
alter database open

ERROR at line 1:
ORA-19838: Cannot use this control file to open database .
I have an Oracle 10.1 database on a Windows 32 bit platform that I am attempting to clone to a new server to make a development instance.
For this particular scenario the database needs to stay at version 10.1. Both servers are Windows Server 2003. Following oracle docs I have copied the home folder and am attempting to run OUI with the clone switch.
OUI crashes and reports the error as "unknown".
OUI also crashes if I try to run it without the clone switch from gui.
Why this occurs, and have confirmed that PATH is correct etc on the new dev server and the other obvious stuff.
I just need a quick way of getting this dev server instance up and running AND maintaining the same database version (10.1). I thought the clone operation would be a good option but don't know how to troubleshoot when the error is "unknown".
how to clone database using cold backup,I want step by step guide for it

View 4 Replies View RelatedI'm using Oracle Database 11g R2 for study purposes.Currently I'm learning about the DBCA clonic templates.I have an Oracle DB 11g R2 X86 running properly in Ms Windows XP Professional SP 3 X86, using DBCA I created the seed template file .dbc and the .CTL and .DBF files, later I copied those files to a server running Oracle DB 11g R2 X86 in Ms Windows 7 Ultimate X86. Again, using DBCA I successfully created the source database through the seed template file, everything was ok.
Now, I formatted my testing server and I installed Ms Windows 7 Ultimate X64 and Oracle Database 11g R2 X64. I copied the seed template file .dbc and the .CTL and .DBF files to "assistantsdbca emplates" directory. Well, I started DBCA to try create the source database and when the DBCA is creating and starting the Oracle instance it shows the errors:
ORA-00604: error occurred at recursive SQL Level 1
ORA-06553: PLS-801: Internal error [56327]
Is it possible to clone my testing DB from X86 to X64 using DBCA clonic templates?
1. I installed oralce with Service_Name=DB1 it works fine,
2. I created another database with dbca named DB2,
3. I connected both system/password@db1 and system/password@db2 without any problem,
4. After rebooting the computer I can connect only the first database DB1 which I installed with Oracle installation. But, I can not connect to the 2nd database which I created with dbca. Error Message Shows: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
DB1 has no problem I can connect to that, but I can not connect to DB2 after rebooting the system. Now I need to know how to connect to DB2.

How to clone database using RMAN FULL BACKUP on different machine? I do not wants to use DUPLICATE Command......
Is there any other way to clone DB? I am using Oracle 11g R1 on Windows Server 2007 (64 bit)
There is a requirement to make a table data in a database (eg: HR database) available in another database (eg: EMP database), instead of accessing it using database link. In EMP database(where data needs to be cloned), data will only be queried and no write operation will be done. Data in remote database (eg: HR DATABASE) will be occassionally fully truncated and reinserted. The plan is to do a similar truncate and reinsert of data (from HR database) into EMP database monthly once using dbms scheduler job. So basically data in just one table needs to be cloned in another database.
Question: For this situation, is a regular table or Materialized view the right choice to clone the table in EMP database and why? The table in HR database (remote database) is not very big.
I am cloning my prod db to test with the rman active clone command. I can successfully clone my DB, but after a few hours or so I see messages in the alert log that I have corrupted blocks in several datafiles. Note, i dont see these messages in my PROD DB therefore I think that DB has no corruption. I have few questions:
1) I was reading tha having tables or indexes set with the NOLOGGING option can cause objects to be unrecoverable. Would this affect my active clone?
2) I know you can either change a DB or tablespace to force logging. Is there a query I can use to determine if the DB is in force logging mode.
ALTER TABLESPACE tablespace_name FORCE LOGGING;
ALTER DATABASE FORCE LOGGING;
3) Lastly how to check as why my clone DB would have corrupted blocks.
Here is the clone command I am using.
rman catalog=rman/rman@proddb target=sys/sys@proddb << EOT
connect auxiliary sys/sys@clonedb
duplicate target database to clonedb from active database nofilenamecheck
pfile=/u01/app/oracle/product/11g/dbs/initclonedb.ora ;
exit
EOT
I'd like to confirm whether its possible to clone a database instance from a RAC cluster to a single server, with an additional issue that the RAC cluster is running Oracle 10g and the single server is running 11g. Can I do that directly or do I need an intermediate step to upgrade the database instace to 11g? Or can I even use exp/imp on RAC?
View 2 Replies View RelatedMy management is asking me to find the best way to migrate our 3.3 TB data warehouse to a new server. I currently use RMAN to back up the database. This is done offline on Sundays, and it takes about 9 hours, compressed backups to disk. Archived log backups are done online, not in conjuction with the db backup.
I have read a number of documents detailing step to use OEM Db Control (aka dbconsole) to clone the database to the new server.
I have a few questions:
1. I need to clone the Oracle SW first, as our current install has patches, so it should take less time.
2. Do you think just restoring from the last RMAN backup and doing recovery would be faster than cloning?
3. On the new server, I have assumed that the root user (not me) would have to pre-create the OFA structure, e.g.; we have some mount points like /f01/oracle/DBNAME or /g01/oracle/DBNAME. I cannot imagine that the Db control Gui or Rman could create that structure on the target server. Is that correct?
4. There seems to be an attitude in my shop that the storage array mount points and OFA would not have to be identical on the target server. Any opinions?
Back in 1995, I successfully manually cloned a database to a new server in an HP environment, but it was only about 70G!!
I am looking to create a DDL-only clone of a 2TB database. The purpose of this clone is to provide developers a preprod-like environment where they can test the syntax of their code changes before deploying to production. The database will reside on a seperate, small server.
As I only need the structure of the objects and not the data, my first port of call was EXP using rows=n. However, when I IMP to an indexfile I see that the initial extents have been defined on the tables (in some cases 1GB!). As stated my clone environment is small, so I would be looking to have these set at 1mb. how I can achieve this? I will want to be able to automate the cloning of the database as much as possible. Perhaps there's some other way other than EXP/IMP?
I have run a standby clone that terminated with error due to few missing LV-s. I removed all LV-s for the clone, recreated them including the missing ones. I ran the clone again,but it skips the files that were successfuly duplicated in the previous clone request that failed. I need to be able to start the clone all over again, but RMAN does persistantly skip duplicating the datafiles that were successfuly processed in the first atempt.
How to ignore the RESUME option so that the clone process would start from the beginning? Where does RMAN keep the info about the successfuly duplicated datafiles in clone standby process? I have tried few RMAN tables , but no luck.
Actually i am not using OCI directly. I have a Delphi application in which I would need to clone an open db connection. Not only username, password, and target database (this is easy and i already do that).
What I would need is also inherit context variables and global temporary tables content status at the moment in which the cloning operation takes place. It seems a very difficult, if not impossible, thing to achieve.
I am trying to create a clone database using hot backup of a database .
STEPS THAT I FOLLOWED
------------------------------------
LET ----- >CURRENT_DB NAME=DEV
CLONE DATABASE NAME=DEVCLONE
steps PERFORMED FORM DEV DB
-----------------------------------------------
- put the database in backup mode using 'alter database begin backup'
- copy all the data files to a different folder
- during copy i have performed some operations on the DB (creating users, tables, dmls etc...)
- in between copying i also performed log switch
- after completion of copy , "alter database end backup"
- created a backup control file in a human readable format (alter database backup controlfile to trace as ........)
steps performed for clone DB side ((DEVCLONE)
-------------------------------------------------------------------
- created a parameter file for the database .
- modified the backup control file so that it will point to the location of copied destination of datafiles
- set the ORACLE_SID
- then 'sqlplus / as sysdba
- starup nomount
- run the modified control file ( created a control file for the clone database)
- recover the database using "recover database using backup controlfile"
I have provided the archive files that it was asking for (archive logs that has been generated in DEV DB)
then i canceled the recovery by typing "cancel"
- recover database using backup controlfile until cancel;
then typed "cancel"
- then try to open the database with open resetlogs but it showed below error
alter database open resetlogs

ERROR at line 1:
ORA-01195: online backup of file 1 needs more recovery to be consistent
ORA-01110: data file 1: 'D:DATA_GUARDDEVHOTSYSTEM01.DBF'
Given facts:
rman is used to backup database A to disk
rman is used to put those disk backups to tape
rman is used to duplicate database A to database B on another host
the duplicate process worked fine before we started testing encryption
the duplicate process worked fine with database A having an encrypted column in one table in a non-encrypted tablespace
Now, database A has an encrypted tablespace with nothing currently in it. The duplicate process now ultimately fails with ORA-19913, unable to decrypt backup.
I am not using encrypted backups, not specifying encrypt or decrypt anywhere in the duplication process. The only thing that is encrypted is the one tablespace in database A. I have the same wallet files on Host A (database A) and Host B (database B). Wallets are open. So why does the duplication process fail because the backup cannot be decrypted?
I got a primary database with a logical standby database running Oracle 11g. I got two client applications, one is the production site pointing to the primary one, another one is just a backup site pointing to the logical one.Things will only be written into the primary database every mid night and client applications can only query the database but not add, update nor delete.And now, I want to apply the latest patch on both of my databases. I am also the DNS administrator, I can make the name server pointing to the backup site instead of the production one.I want to firstly apply the patch on the logical one, and then the physical one.
I found some reference which explains how to apply patches by adopting "Rolling Upgrade Method". however, I want to avoid doing any "switch over" mentioned in the reference because I can make use of name server. Can I just apply patches as the following way?
1)Stop SQL apply
2)Apply patches on logical standby database
3)let the name server point to the backup site
4)Apply patches on the primary database
5)Start SQL apply
6)Let the name server point back to the production site
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 ?

We have configured oracle one way stream between two databases. Source database is capturing the changes (No downstream configured). Configuration was working fine but destination database was lagging behind very much i.e about 15 days behind the source database. We are ok with this but the problem is now that , as per client request we have restored previous backup and open the database with resetlog option in source database. After resetlog , archivelog sequence has been changed and stream is not working.
Can I apply the previous archivelog (before resetlog archivelogs ) in destination database anyway.Source database is a production database.
