Can i duplicate a database that is in a different CHARACTER SET?
If i can't made the duplication in a direct way, how can i convert or transform to duplicate a database from one character set o another?
I have the following question:
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 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 have a CLOB containing a XML code and all XML tags where created using the DB charset: WE8ISO8859P15.
For example:
{code}
<?xml version="1.0" encoding="ISO-8859-1"?>
<certidao xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<funcionario>
[Code]...
I need to maintain this charset value.
But now I need to convert all my CLOB data into UTF-8 charset for external requirements and stored this new CLOB in a table column.
I can't change the charset of the session. I've tried to use a function
{code}
FUNCTION convert_xml (pcl_xml IN CLOB)
RETURN CLOB
[Code]....
This function apparently works, but when I try to validate the XML content (after I replace the encoding="ISO-8859-1" to encoding="UTF-8") the validation software tells me that I have some characters that should not be present in a file using UTF-8 encoding.
I have 2 identical databases set up as follows:
- 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 issue with regards to duplication of an active (prod) database to a test database. This is my sql run by RMAN:
SPOOL MSGLOG to '/proddb/u01/app/dupe.log';
CONNECT target sys/oracle;
CONNECT auxiliary sys/oracle@MWTEST;
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
RUN {
duplicate target database to MWTEST from active database;
}
CONFIGURE DEFAULT DEVICE TYPE TO SBT_TAPE;
It stops however in the middle and wouldn't continue. There is still huge space for the test database (3x the current size of prod database).
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.
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
Step 2 :
==> tnsping DATABASEB

I need to configure character set for my database. I have 2 options:
AL16UTF16 - require 2 bytes per character (fixed length)
UTF8 - character length - 1 until 4 bytes. (variable length)
until here ok...
The AL16UTF16 certainly will occupy more space than UTF8. So my question is, When would I need use AL16UTF16 character set mode?
I hear one time, when a database write many values with the same length. it does it in the same HD cylinder. So the HD arm could with a single movement read all the fields in cylinder completely. Improving the read/write performance.
I am installing oracle 11 by silent installation.I want my charset to be UTF16, how can i change it.

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.

Backup-Based Duplication Without a Target and a Recovery Catalog Connection?
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

The errors are : Procedure entry point 'BlaBla' could not be located in the Dynamic Link library 'AnyName'.
I notice that i have 2 versions of the libraries in OracleHomeBIN (one version 8, one version 11). The programs that start the OracleAgent,Service and DataGatherer call the old libraries but expect to find values that can be found only in new libraries.
I have a requirement to put together a Oracle SQL template to create re-usable DDL/DML Scripts for Oracle databases.Only the Oracle DBA will be running the scripts so permissions is not an issue.
The workflow for any DDL is as follows:-
1) New Table
a. Check if the table exists from the system/admin views.
b. If table exists then give message "Table Exists"
c. If table does not exist then execute DDL code
2) Add Column
a. Check if Column exists for a given table from system/admin views
b. If column exists in the specified table,
b1. backup table.
b2. alter table to make changes to the column
b3. verify data or execute dml script convert from backup to the new change.
c. If Column does not exist
c1. backup table
c2. alter table to add column
c3. execute dml to populate column with default value.
The DML scripts are for populating base tables with data required for business operations.
3) Add new row
a. check if row exists by comparing old values of each column with new values to be added for the new record.
b. If exists, give message row exists
c. If not exists, add new record.
4) Update existing record (We have createtime columns in these tables so changes can be tracked)
a. check if row exists using primary key.
b. If exists,
b1. deactivate the record using the "active" column of the table
b2. Add new record with the changes required.
c. If does not exist, add new record with the changes required.
