Database migration to another server

I have one production oracle 10g database on RHEL4 and I want to migrate the data with another server RHEL4.
I have an RMAN backup.
Is it sufficient the 2 commands
rman> restore database;
rman> recover database;
to migrate the data in the second server?
Thanks

Why don't you duplicate the source database on the target.

Restore database noarchivelog to another server in ASM

I have to migrate a database 10g with noarchivelog with filesystem to another server with ASM.
Could you help me to do it?
Thanks.

ok, I put the database in archivelog but I don`t understando the link "http://www.oracleflash.com/10/How-to-migrate-Oracle-datafiles-to-ASM-storage-via-RMAN.html".
First, I have moved the database to the new server, now I have the database with filesystem but in the final server with archivelog. OK.
The steps are:
first, I have to modify the parameters of db_create_file_dest, etc, to +ASM.
I hve to shutdown the database, open nomount, restore controlfile and backup as copy.
Is it correct?,
one question, the restore controlfile, I suppose that I have to have a previous backup with filesystem of controlfile?
Thanks.

MDM DB Migration to Another server (OS may change for DB)

Hi MDM Expert
We are currently using MDM 5.6 SP06 with HA (Microsoft Cluster) Active/Passive.
DB and MDM both are running on same machine
Now we want to move our Database to another server (OS May change on target DB).Please note we just want to move DB only not MDM Server component
After DB move to another server we also wanted to have DB in HA, i mean Active/Passive and i know we need additonal to make it HA
Can you please refer us any document which will help us for accomplish this requirement?
Also let us know if there will be any negative implication on MDM Servers component after moving DB to another server
We are also using Oracle failsafe for MDM HA configuration
I really need expert help here
Thanks in advance
Thanks

Hello Augusto,
if i understood you correct only the host of the database is changed. The ABAP and JAVA instances are still running on the same host as before?
If yes then this is pretty easy ... you can shutdown and copy the database with scp/rsync .. or if you have a shared storage you can just remap the disks to the new server.
As you described, that the hostname of the DB host will change you have to do 2 things
1) Change hostname of entries in tnsnames.ora (for more information about tnsnames check sapnote #562403)
2) Change the host connection entry in the secure store of the Java instance (http://help.sap.com/saphelp_nwpi71/helpdata/de/ec/9432d189c445cdacdc7e520981b4b6/content.htm / Database Schema password should be change or not)

EBS database migrate to exadata server.

Hi Experts,
My EBS database is 11.2.0.3. I'm going to migrate EBS database to exadata server. Please advise what patches need to be applied on exadata server for EBS database migration?
Thanks & Regards,

Hello Angela,
I think what you're looking for is in My Oracle Support document ID 1392527.1 "Oracle E-Business Suite Release 11i & R12 Patches Required with Oracle Database 11g Release 2 (11.2.0) on Exadata". It has a detailed list of patch requirements for different combinations of EBS and database versions.

How slow - if database is on another server?

Hello,
I want to create a French version of my website.
The original - creme-de-languedoc .com is on a server in
Texas. Which is great for a .com. The French one is on a server in
France, which I'm told is better for .fr sites when Google.fr is
concerned.
Although the pages and images are all on the French server,
the database behind the site is still in Texas.
So far, the pages with dynamic data are loading very slowly.
Is this because the data is on another server in another country?
If so, what's the best way to speed things up? The DB is
added to daily, so I don't want to really have to update a copy of
it constantly on the French server.
Any ideas?
Thanks,
- Greg

Greg,
I don't know if Replicate would work for your purposes or
not.

One obvious caveat is that your subordinate server must only
allow
SELECT access. Probably some DB guru's will rip-me-a-new-one
for even
suggesting such a thing. Oh well, food for thought. Check our
MySQL.com and read up on Replicate, then ask someone there if
this is
pure folly.

Database Restore on another Server

Could someone please explain to me (or point me in the right direction) the procedure (How-To) on how to restore a database to another server?
please understand I'm just learning oracle and this is all new to me.
e.g., I have good backups of a database. I restore those database files (control files, dbf, redo logs) to another server. What are the steps in bringing that database up online on a different server?
...thanks

Database Migration MS Sql Server 2008 to Oracle

I have downloaded the latest updates for SQL Developer and am attempting to migrate my SQL Server 2008 DB to Oracle 11g. I get the following error when attempting to test my Sql Server connection:
Status : Failure - Test failed: I/O Error: SSO Failed: Native SSPI library not loaded. Check the java.library.path system property.
After attempting and following several posts, I have been unsuccessful in getting past this error - I have downloaded and placed in the specified directories the various .dll's suggested....
Any help is of course appreciated.

Boy do I look foolish. I told this guy that the owners of the application answer questions here... suerly he would get a reply.
Such is the problem with "free" software. No one to blame when it doesn't work.

Database migrating to secondary server

I have 3 servers in my Exchange 2013 deployment with 2 being the primary database holders for my 2 active databases and the 3rd server being a failover for either. One of my databases is now activating itself on the failover even after I manually activate
it back on its primary holding server.
I am not seeing any events or warnings that would cause this so I am somewhat perplexed as to why the DAG is shifting it off to the failover. I have verified that the activation preference numbers for the database on the 2 servers is set correctly
and that there is not an issue with low hard drive space.

Hi,
First, please check if the affected database is in healthy state. You can use the Get-MailboxDatabaseCopyStatus | fl cmdlet to check status information about database. Here is an article which can help you, please refer to
Monitoring Database Availability Groups.
Please check the cluster and application log on the Mailbox server which the failover database locate in to see if there is any clues.
Best regards,

Siebel database migration from Sql Server 2005 to Oracle 11g RAC.

Hi,
We would like to migrate our Siebel database from Sql Server 2005 to Oracle 11g RAC. Can you suggest the best way to do that ?
The current configurations are:
Application : Siebel
database : SQL Server 2005
The hardware can be changed if needed. Can you please suggest the best approach ?
Thanks,

Hi Naveen,
We would like to migrate our Siebel database from Sql Server 2005 to Oracle 11g RAC. Can you suggest the best way to do that ?You will need much more which suggestions.
You will need a Siebel professional which has done this type of migration. Migrating the Database is not a task so hard, after migrating your environment should be functional and healthy it is usually the task problematic.
The hardware can be changed if needed. Can you please suggest the best approach ?We can recommend the minimum recommended, but this documentation already does, you need to do a analysis on your environment and ask a vendor Siebel tell the which is recommended for you and how to find the best "number" for you, in your case is very hard because everything changes.

DataBase Migration from SQL server 2005 to SQL server 2012

What are the challenges and steps to be taken care for proper migration of the Database.
Applications are using the Visual Studio 2012.
saikalyan

Few things that I can think of -
Verify all logins and users are migrated correctly.
Some of the SQL Server 2005 features/code could be deprecated in SQL Server 2012. Changes could be required before or after migration.
Some of the queries could have different performance (better or worse) on 2012 due to changes in query optimizer.
The applications/SSIS/DTS config files are updated to use the new server/instance name.
DNS alias names from the old servers (if used) are moved to the new server to have minimal impact on connection strings.
Plan for downtime of applications and batch processes.
Notify developers about the migration and the new server name(s)

How to connect to a MySQL database in another server

Dear friends,
I am using Oracle SQL Developer 1.5.3 and I need to connect to a MySQL database located in another server.
I am trying to create a new connection, informing connection name, username and password. Supposing that "Hostname" is the IP server address, I click on "Choose database", but I always receive the following error message: "Status : Failure - Cannot connect to MySQL server".
Please tell me what I should do to solve this situation. Thanks in advance.
Best regards,
Franklin

You need to configure your mysql database to accept connection from your PC for the user you used.
For example,
GRANT ALL ON *.* TO 'someuser'@'somehost';
FLUSH PRIVILEGES;

Migration from SQL Server 7 to oracle 8.1.7 on windows 2000 professional

Hello All,
I am currently working on Database migration from sql server 7 to oracle 8.1.7.
My setup is as follows:
1. Both the databases (sql server and oracle are on the same machine )
2. My sql server database contains 200 tables and 190 stored procedures, which need to be migrated to oracle.
When i am trying to capture the Source database details, its capturing evry thing but when its mapping at the end ...it says "MAPPING ROLE PUBLIC" and its not proceeding furthur..What do u want me to do ? i waited for approx 1 hr , still its not proceeding....How to resolve this bug ?
Also please suggest me the best methodology for Migrating the stored procedures. allmost all my stored procedures have TEMP Tables implemented in it. Please help me in this...
Also please let me know the Timeframe estimate for this total thing to be done..
Waiting for your reply,
Thanks and Regards

Migrating master database to another server (DR testing).

So I was tasked to do some DR testing, by moving one of our environments to another. I was tasked with moving 1 user database called Vant, master, and msdb. I managed to accomplish it, but it wasn't easy and a little messy. I'm looking
to see if you guys can help me clean my steps up a bit.
Environment backgroud.
Both environments are SQL Server 2012 Enterprise
Build: 11.0.3368
Instance Name: Default
Process
I took all 3 backups from my source server and placed it in a network location where my destination server can access.
1) I began by trying to restore master database by placing my instance in single user mode, backup restored.
2) when I removed the destination instance from single user mode, the service would not start, did this a couple of times, but no luck.
3)I also made sure the startup parameters were pointing to the right folder location
4)Then I thought, maybe it was the folder location where it restored to, that was causing the problem because they were different; so I went ahead moved master into a folder location that would match the source, i also changed the startup parameters, but
the instance still wouldn't start
5)So then I checked the event logs, and noticed that SQL Server was looking for databases that were on the Source Instance, as well as some of the system databases that I hadn't moved the files to the new folder location
6)Restored the original master database from the destination server so that I could get the service going
7) moved all the system databases from the old folder location on the destination server to where master now resided; created two empty databases with the names the event log was looking for.
8)Restored master database from source server, and the service finally started up
9)When I went into SSMS, I noticed that the two empty databases I created were in recovery pending
10) dropped one of the databases I didn't need, and restored the Vant database, as well as msdb; everything looks good.
So there it is, I totally don't feel good about this. I don't like the fact that the databases came up in "recovery pending" and also that I had to create the databases it was looking for before I could restore and start up the service, but
maybe that's just how it is. Any advice you can give me on how to clean this up would be much appreciated.

Hi,
Did you reffered to Microsoft doumentation on how to move system databses.
http://technet.microsoft.com/en-us/library/ms345408(v=sql.110).aspx
For user databse backup when you restore on different server you use with move option to physically give location to mdf and ldf files.
Moving system database is little tricky

Migrate oracle database to Microsoft sql server 2005

Hi All,
I have to migrate production oracle database to Microsoft sql server 2005. Below are the details:
Oracle database version: 8.1.7.4
Platform : Aix
Kindly help me out

Well, the traditional way would be to dump out all your data from Oracle tables as comma delimited flat files and import into SQL server. Plenty of examples online, like this is one by Mark Powell: http://www.jlcomp.demon.co.uk/faq/flatfile.html
Or if you have the budget you could think about buying a data mapping tool like File-Aid
As mentioned by another poster, you will still need to figure out how to replace all your triggers, stored procedures, etc on your new platform of course.
