Server Administration :: Oracle DB Server Migration Checklist
Apr 11, 2012
We will be having a meeting with our client regarding their Database Server Migration (They are planning to buy a new server). Their current database is Oracle 10gR2, they will not upgrade to 11g, they just plan to migrate to a new more powerful machine.
I was planning to ask the following questions.
1. Specifications of the current server and the new one.
2. Operation system (I think they will use same OS, just an updated one)
3. Can the business afford full downtime on current servers?
4. Size of the DB, because it can take hours to move large files.
And is there documentation regarding Server Migration (Change of machine only, not database upgrade or anything,
We have to migrate our database from current OS (AIX 5.3) to Solaris 10. We'll do it through expdp / impdp. Is there any other way to do it as well?
Also, we have dataguard configured at current setup. So is there any way we can take backup of existing database at DR & restore it at new server (Solaris) or we'll have to take a fresh backup from DC (after migration) & ship it to DR & create a new standby?
Recently we are planning to migrate oracle 10g to 11g. We are migrating PHASE WISE (Schema wise) as this is a 50TB of Production instance. We are using Oracle Golden gate for this purpose.
Is there is any way that we can migrate oracle jobs from 10g to 11g?
I am migrating an oracle 10g to 11gR2. i am a bit confused. The developers in my work place have a tablespace for storing table and a different tablespace for storing indexes.
For the migration i am using exp and imp. My question is how i am going to migrate the indexes from 10g to 11gR2?

Currently we are having Microsoft Windows Server 2003 standard Edition service pack 2 and we are trying to migrate it to microsoft windows server 2008 Release 2 standard Edition
i have to migrate the current production database to test 10.2.0.4 on windows. Any non-export way to upgrade 9i to 10 g?
i have following steps me know if i am wrong? 1) ALTER DATABASE BACKUP CONTROLFILE TO TRACE 2) shutdown oracle 9i database on server A 3) copy database file, controlfile, redolog, and other files to new server B 4) alter the controlfile backup with new location of bdump, udump, and log file and data file locations 5) user oradim ORADIM -NEW -SID SID [-INTPWD PASSWORD ]-MAXUSERS USERS -STARTMODE AUTO -PFILE ORACLE_HOMEDATABASEINITSID.ORA 6) start dabase in upgrade mode 7) run catpat.sql and util102.sql take backup 9) open database for users
I want to migrate our production database from 9.2.0.8.0 to 10.2.0.4.0 through startup migrate ,so request you to kindly provide me a step by step doc or some reference link pertaining with same.

can i migrate 9i database to 10g database, what are the steps for full import??
We are planning to migrate data from an application called clintrace to another application called argus safety. Both the applications are related to pharmacovigilence safety operation. Both the applications functionality are similar. So both the database are having the same data though the table structures might be different. Both the database are oracle clintrace db is 9i and argus db is 11g.
We had a new outsourcer who completed migration of 1 of our system running under Oracle10g-Solaris 10. We created an inventory script that will list all objects counts of SYS, SYSTEM and ORACLE and all other schemas. This script will be ran before (old server) and after migration (to new server). After migration to the new & bigger server, we noticed from the output of the inventory script for SYS/SYSTEM object counts had been reduced compared from the original/actual value (from the old server). Our outsourcer said that this is not an issue since SYS/SYSTEM objects are not transactional and cannot be controlled.
As we will conform that the migration was completed successfully by our new outsourcer.
I have Windows server working Oracle 8.0.5.I have to migrate to another server that is Oracle 11gR2 on Windows 2008.Some say I can't do Export and Import directly.And some say DBlink is not working from 11Gr2 to 8.
What can be fewest step to migrate?Somebody try to use 'Oracle directory' and VB and Powerbuilder program to send data and DDL from 8 to 11Gr2.
We are having oracle 9i as database and migrating to sql server 2008. Our oracle 9i database connects to another oracle databases and these databases are having different oracle version(9.2.0.8.0, 9.2.0.7.0,10.2.0.5.0,11.2.0.2.0,9.2.0.6.0,10.2.0.4.0,8.1.7.4.0 )
I do have two queries :
1) how to connect from Sql server 2008 R2 to different Oracle databases
2) How will other oracle databases connect to Sql server 2008 R2 database
I have migrated from postgres to oracle entire databases however some tables have spaces how can they be removed and how can i found out all the tables in a schema with spaces?
Migrating the LIVE server to a NEW virtual machine.2 databases reside on the LIVE server, one runs in archivelog mode &other no archivelog modeOld server-Windows 2003 32 bit, oracle databases 11.1.0.7.0New-Windows 2008 64 bit,Oracle databases should be 11.2.0.3.0Just want to clarify the following1)When installing oracle, what would be the best option-create and configure a database / install software only(later create database using dbca) ?why? Just want to know if there will be a difference at all in these 2 methods.2)What is the best way to migrate the data in the database, datapump or rman (rman takes full backup in the present "live" so this can be moved to "new live" and can be recovered)? What would be the method with least downtime?(Once the data is transferred, the database in the "old server"will be deleted)3)The structure of the data files (folder path) are going to be different in the old and new servers, so I have to precreate the tablespaces, so will the impdp fail in this case?
im trying to migrate Sybase 12.5 to oracle 11G R2 on linux all tables are fine expect one which fails with error
"SQL Error: ORA-01841: (full) year must be between -4713 and +9999, and not be 0 01841. 00000 - "(full) year must be between -4713 and +9999, and not be 0" *Cause: Illegal year entered *Action: Input year in the specified range"
i have change the data type from CHAR to VARCHAR2 etc as for the datatype date shows as date on the tool - I'm using sqldeveloper from oracle.
i am trying to install Oracle 10.10.2.0 on Windows Server 2003 standard x64 Edition Service Pack, but when i try to run the installer or open DVD it gives me below error.
"The image file D: is Valid, but is for a machine type other than the current machine."
I was trying to delete the database in the test server. When i was deleting listener was already stopped, i continued deleting using dbca, it shown me some alert that datafiles cant be deleted because system could't find database, since listner was stopped so only service was deleted(the one showing in the windows administrator toolsservicesOracleServiceTEST).
All the datafile parameter files are still there. How can i delete the datafiles and parameter files belongs to that database or how to create the deleted service, so that i will start the listener and do the complete deleting of the database.
I am trying to find the unix process for one of my application in the database but I am unable to view the same. To simulate, I did the following.
1. My database runs on different server. 2. I invoked "sqlplus" from another unix box to login to the database. 3. I found that the process id (ps -ef |grep sqlplus). 4. When I execute the below mentioned query it does not display the process id that I am looking for. But the osuser, username, program and machine details are correct. How can I know the process details from the database?
SELECT SYS.GV_$SESSION.OSUSER, SYS.GV_$SESSION.USERNAME, SYS.GV_$PROCESS.SPID, SYS.GV_$SESSION.MACHINE, SYS.GV_$SESSION.PROGRAM, SYS.GV_$PROCESS.PROGRAM ,SYS.GV_$SESSION.SQL_ID FROM SYS.GV_$PROCESS, SYS.GV_$SESSION WHERE SYS.GV_$PROCESS.ADDR=SYS.GV_$SESSION.PADDR and SYS.GV_$SESSION.USERNAME='TEST' and SYS.GV_$SESSION.MACHINE like '%hostname%'
I want to install Oracle 11g R2 in windows 2008 64 bit server. How can I know whether my server is ready to install Oracle ie is all components are available in server or any patch is to be applied etc.
I'm trying to connect a oracle client application on the client machine to a remote oracle server on the server machine but i get a connection fail.
On the server machine I configured oracle server in the following way:
Installed oracle server. Created a database "DB_Test" with the database configuration assistant Created a LISTNER with the Oracle NET Manager with the following parameter:
Protocol: TCP/IP HOST: server pc hostname (ENZOVAIO) or server machine address ip (192.168.0.71) in the network lan Port Number: 1521 Created "dbtest" service with the Oracle NET Manager with with the following parameter: Service Name: "dbtest" Protocol: TCP/IP HOST: server pc hostname (ENZOVAIO) or server machine address ip (192.168.0.71) in the network lan Port Number: 1521
All services on the server machine are running and I opened port number (1521) in the router. On the client machine I installed SQL PLUS and SQL Developer.
With SQL Plus as by the official documentation I have entered the following command:
CONNECT username/password@[//]host[:port][/service_name]. In my case is: CONNECT SYSTEM/oracledb@//ENZOVAIO:1521/testdb.
With SQL Developer I have entered the same parameter.
But with both SQLPlus and SQL Developer the connection fails.
We performed image copy of production Oracle server (OS and instances) to a backup server. After a few weeks, we try to restore a latest Oracle database backup from production server to backup server. As we know, Oracle instance must be unique on the network.
Even we log on to backup server and bring up the instance, I think that still point to production instance since all init file, TNSNAMES.ora and listener file are still same. If we restore the database, we will end up bring down the production instance and restore on top of productions. How to change instance name on backup server including TNSNAMES, sqlnet, listener files in order for us to restore Oracle database from production to backup server?
I recently installed Oracle 10g on my windows Xp laptop. It has become considerably slow since then. I want to start the database server only when I need it, and not every time I start my laptop. I looked around in OEM and did found a way.
I am connected as System. It was the only user I set-up a password when installed the database on personal computer.
SQL> alter user sys identified by mypass007 2 / User altered. SQL> connect sys/mypass007 ERROR: ORA-28009: connection as SYS should be as SYSDBA or SYSOPER
