I'm trying to set up Active Database Duplication between 2 Oracle 11g servers. Each server is identical, with the following characteristics:
- OS: Windows Server 2008
- Version: Ora11R2 (64 bit)
- DB Name: orcl
- Filesystem: asm (using grid infrastructure)
In addition, each server has been configured with the same sys passwords. The databases themselves were configured during installation (so the setups are about as basic as you can get.)
Now, I've done all sorts of research into how to do this. I've found plenty of good sources, but they seem to all have differences in the details.Here's what I've done so far:
- The TNSNames.ora file on each server has an entry for 'src' and 'dest' (sourca and destination) respectively
- I created an entry named 'SID_LIST_LISTENER' in the listner.ora file on the source machine. However, should the sid_name in this entry refer to the source or destination machine? Or does this listener entry belong on the destination machine instead?
- A lot of the examples require the setup of a new password file and spfile. Are these entries necessary if I'm using the same file structures/user names/etc. on both servers?
I'm trying to set up active database duplication between 2 Oracle 11g servers.
Both servers were set up with identical configurations (same directory structures, file systems, SIDs, and sys passwords.) Both oracle instances were created at the time of software installation.
Here is how things are configured: - Version: Ora11gR2 - Oracle service name: orcl - File system: ASM - OS: Windows Server 2008
I've done some research and found several sources giving instructions on how to set up active database duplication (including a blog engry by rajabaskar on this site), but each site seems to have different details.
So, here's what I have so far:
- Set up entries in each TNSNames file... each has an entry 'src' and 'dst' (for source and destination)
- A new listener has been added on the source machine
- on the destination machine, run the 'oradm' to create a new SID. However, is this really necessary? Since the service names are already the same
- I'm also supposed to create a password file on the destination machine using orapwd. Again, is this necessary, if I'm using the same passwords on both machines?
Am I on the right track? Should I have created an actual database on the destination machine or should I have started with just the software installed?
I like to duplicate the database DATABASEA to DATABASEB and need to be run in same server. I tried to bounce the listener & databaseb instance multiple times but no lucky.
Step 1 : The instance DATABASEB is in Nomount stage

I try to duplicate a database on Host B with ORACLE_SID=hostb from an offline full backup plus archive log backup was taken from Host A with ORACLE_SID=hosta. Host A and Host B cannot communicate between them.
I don�t want to make a full restore of database, i want to make a duplicate database from that offline backup.
I need the duplicate database must be run with different ORACLE_SID and different DBID.
PD: I was reading the Oracle Documentation about that but i can�t find a step by step guide to follow.
Environment
Oracle 11gr2 with a Linux OS on x86_64 on host A and host B.
I'm checking the possibility to use Active Directory to log on the our Oracle databases. But only for dba's and developers, not application users. We use Oracle 10.2.0.4 (and soon 11g) As OS on the databaseserver we use AIX5L 5.3
Is it possible to implement Active Directory on databases running on AIX ? If it is possible, what must be done to get it to work, software ... etc ?
I have a table in Oracle with a column userid and i have a userid column in Active Directory. based on this i want to query the Network ID and update in one of the Group in the Active Directory. how to get the results?
- Version: Oracle 11gR2 (64 bit) - OS: Windows Server 2008 - File System: ASM (with GRID Infrastructure)
Both instances are virtually identical... Same directory structures, same SYS passwords. The only thing that differs is the instance name (one is ABC, the other is XYZ).
Now, both databases are up and running, both have users on them, and both can accept remote connections. What I want to do is set up a very simple 'copy' system so that everything can be extracted (via RMAN) from the first database, and replace the database on the second. (Then, the user can log into XYZ with the same usernames/passwords they used on ABC.)
Here's what I'm doing so far:
On the 'source' database (ABC) I run RMAN as follows: rman target / nocatalog configure controlfile autobackup format for device type disk to 'C:\temp\CF_%F'; configure channel device type disk format 'C:\temp\bkp_%U'; run {backup database; backup archivelog all; }
Now, I'm not completely sure of what to do on the 'destination' database. I've seen multiple web pages with instructions that require the creation of a new instance using 'oradim' and the creation of a new password with 'orapwd'. However, is that necessary if I have the same sys password on both databases, and I want to use the same XYZ instance name on the destination machine?
Would it work if I used 'delete database' on the destination, and then used the RMAN 'Duplicate database to XYZ backup location 'C:\temp\'? Or does it HAVE to be a new instance created with oradim?
And if I DO have to use oradim to create a new instance, will the data be accessible through XYZ too?
I have oracle 10g up and running on Solaris 10, from windows I would like to connect to sql plus through windows authentication, for that I have already made sure that remote_auth = true and have created user in oracle with OPS$. But still I cannot connect.
I have the same setup but with oracle on windows server, the os authentication from windows clients works just fine.
does oracle 10g on solaris 10 supports windows os authentication?
I have done many duplication before in sinlge instance databases using a backup tool and rman catalog. At the moment i was trying to do a RAC database duplication and facing some issues. For this i was doing a testing on my 1-node RAC. Primary and duplicated database is on the same Host and oracle version is 10.2.0.3. I perfomed following steps:
1.Created a DUPL database using DBCA.
2.Created a pfile using spfile.
3.Dropped all the datafiles, controlfiles and redo log files.
4.Started the database in nomount using pfile.
5.Disable cluster related parameters in pfile.
6.Took a full backup of the MAIN database with archivelog on disk.
6.Duplicate the database and it is done successfully.
7.Shutdown the instance and enabled cluster parameters.
8.Start instance using SRVCTL fails with error CRS-0215: Could not start resource 'ora.DUPL.DUPL1.inst'
But if start the instance using sqlplus it comes up nicely. There is not much information in alert log files.
creating the standby database from Active database using RMAN and getting the below issue after i executed the duplicate command.
Version of Database:11g(11.2.0.1.0) Operating System:Linux 5 Error: RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure of Duplicate Db command at 12/21/2012 17:26:52 RMAN-03015: error occurred in stored script Memory Script RMAN-04006: error from auxiliary database: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor [code]....
provide any work arounds to proceed further in creating the standby database.
The script has successfully created on standby db all controlfiles and also has copied 2 data files DATA01.DBF and DATA02.DBF into the correct location. Then the errors above kicked in and stopped the rman dup process.
I am getting starting with rac environments. I need to configure a two nodes active/active with rac and I need to know if always using rac both nodes will be active or if I have to do that at some point when installing. I have reading some docs from oracle and others authors about rac and its configuration process but that is not understood for my yet.
I've got a physical standby database and I'm now licensed for Active DataGuard. I would like to automate the ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION command to be executed right after the STARTUP command so that whenever the database is started by our DBSTART script, it activates READ ONLY W/APPLY immediately after start without manual intervention. This is probably simple, but I figured I'd ask before starting to pore through documentation.....!
I have a active data guard database which is copy of my production database. can i backup the active database using RMAN? The ADG is a read only and dont know, if RMAN can backup an read only database.

I recently applied the Oracle® Database Server Version 11.2.0.1 Patch 16 I have several databases running on this box with the same application.Since then I've had lots of customers complaining about slow systems. The server has plenty of RAM availableI also have several other servers all on the same versions, same patch, running the same application with no issues.
Looking at v$session there are often lots of active sessions that have a sql_address of "00". I've never seen this before and I regularly look at v$session, as you can see for below these have been running for a while. The sessions do drop off but I am at a loss as to what is happening.
select username, last_call_et, sid, serial#, user#, status, sql_address, sql_hash_value from v$session where username is not null and status = 'ACTIVE' order by last_call_et desc, sid
We are using oracle as database in our application. For high availability we have a cluster of multiple nodes and the data is replicated using oracle streams. All the nodes in the cluster are active. We do not have any concept of stand-by.
Now we are planning to use oracle RMAN for backup and recovery. RMAN user's guide doesn't recommend any strategies for such deployments. It mainly focuses on primary/stand-by deployments.
I've Googled several times but the result is 50% null ^_^
How can I use the Active Directory to route the clients request to the Oracle Database server so that I can do the basic operation on the Oracle DB remotely.
I want to install an active / passive Oracle Configuration for our new 11gR2 system. We do not want to go full blown RAC as yet. We already have an 11gR2 instance that I plan to CLONE to the production server(s).
So. detail the steps that I need to follow .
i.e. configure the 2 servers (VIFs/Interconnects) Install GRID/CRS Clone over the database (do I do this as a SINGLE NODE RAC?)
What two Active Directory services are stopped when you install Active Directory before Oracle 10g? I know the error message for that and I know why it happened but I just need to know the two services so I can start them again. I think it happened because I installed Active Directory first so when I installed Oracle second it stopped two services and I just need to know them. The error message is:
Active Directory is missing binaries, please restart and try again
I want to delete the duplicate rows in a table. there is no column which can be used to differentiate between the rows.
SELECT column_name1 FROM [table] WHERE column_name2 = cond GROUP BY column_name1 HAVING COUNT (column_name1) > 1
from the above query i can find the duplication in the table and can delete through it. But what i want one record of each duplication not to be deleted most probably the record added last to the table.
I use the following script to duplicate a target to an auxiliary instance. This works fine once.
However if I run it a second time it will create a new set of datafiles leaving the original files in place taking up space.
Is there something that I can put in the script that will stop this happening.
I know I could probably put a "set newname for datafile" clause for each datafile in the target database, but this makes the script over complicated and I would like to keep it as generic as possible.

I'm creating oracle form to allow the user to register a new record in a table, I want to check the duplication in Four tables! which means, the user is able to save the record if it's NOT already registered in the other four tables.By checking P_ID (user parameter). this is my
Declare v_count number; begin select count(*) into v_count ---Checking the 1st table from 1_table where p1_id=:p_id; if (v_count>0) then message ('Duplicate'); [code]....
I have a form that used to enter new employees , if the employee ID already registerd then the user can ONLY update the information and NOT adding the same ID with new info.
int the ID item in when-validat-item trigger I put this code
begin
IF :SOURCE_CODE IS NULL THEN MESSAGE('PLEASE ENTER SOURCE CODE'); ELSE declare --chg#13-3169 nada
[Code].....
in the save button the code is : commit;
The problem Is : a new record with same ID is inserted every time !! Duplication is happining
i have read from documentation but getting some error.
