Server Administration :: Migrate Two Different Databases To Oracle?
Jul 11, 2012
I have to migrate two different databases to oracle.i have made two Migration Repository for each to do the migration, migration is done.but i would like to know can it be done with one migration repository.if yes then with one is best way to do it.data of two databases is different but table and sp are 99% same.
I have the task to migrate the total databases(Exact copy to be moved to another server).The current server is going for format.After I did the following steps I am getting the tablespaces(databases)-4 sizes same ,but I am facing issue like some default tablespaces i.e temp,system are not matching.
temp tablespace *************** current server - 4.0(approximately) Migrating server - 160 MB
System tablespace ***************** current server - 580 MB Migrating server - 220 MB
Also I checked the tables are also matching for the 4 databases.Also Provide the solution or method which is correct.
steps done for migrating(By me) ******************************** EXPORTING DATA USING DATAPUMP *********************************
1 From command prompt MKDIR 'c:oraclexeapp mp';
2 From SQL prompt conn system/kotak;
3 create or replace directory dmpdir as 'c:oraclexeapp mp';
4 grant read,write on directory dmpdir to kotak;
5 From command prompt
expdp system/kotak@xe full=Y directory=dmpdir dumpfile=xe.dmp logfile=expdpxe.log; IMPORTING DATA USING DATAPUMP ***************************** in another server machine
1 From SQL prompt conn system/kotak;
2 create or replace directory dmpdir as 'c:oraclexeapp mp';
I have to migrate production database version 10gR2 on windows 2003 server to oracle 11gR2 on windows 2008 server . So far i have just installed the oracle software on 64bit windows 2008 server. How to move the data or migrate from old server to new server .
I am on Oracle 11.2.0.3 on Linux. In my production database, I am getting this alert, in the alert log:
--the below two lines are from alert log. Error 604 trapped in 2PC on transaction 50.73.546578. Cleaning up.
--query from a data dictionary view SQL> select count(*) from DBA_2PC_PENDING; COUNT(*) ---------- 1
When I query the production database I see that there is one row in the DBA_2PC_PENDING view. But I dont' know how to identify which are the databases that are involved in this distributed transaction. That is my first issue - how to identify which are the two databases that are involved in the distributed transaction?
I want to compare two users on different databases, actaully there are two users one in user a on database a and another user b on database b they have same tables, and everytime when a table or object is created on user a (database a) i will take the table name ,procedure or any other object from user_objects based on ddl_created date and then i need to recreate the same on user b on database b, is there a way to find out tables which are not only created but also i need to check whether if there is any column added or any change in procedure or any other objects.Is there a way to generate the scripts based on list of objects selected from user_objects. all i want is.
a)Find out the list of objects added along with creation scripts b)find out the list of objects modified along with creation scripts.
We have and oracle 8i database that has an application that has part of it developed by PL/SQL and the other part on portal 309,is it possible to convert to MS/Sql Database,what tool can we use or what steps do we have to go through to achieve this.
My requirement is we are planning to migrate the sql server data to oracle. what is the way to do migration from sql server to oracle. if any tools are there for migration.Previous we used sql developer( which is provided by oracle i.e. freeware ) tool but it was created only table structures not ported any data.
I am using Oracle database server and I want to show existing databases on that server. Are there any SQL plus command to list all databases there in the server?
I've inherited a 10.2.0.1.0 instance running on a windows 2003 box; running fine, no problems other than system has been in production since 2005 and has gotten pretty old and tired. This old box has one tablespace on it... called "gateway".
I've installed 11.2.0.1 on a new (Windows 2008 R2 Enterprise 64-bit) server and created an empty database also called "gateway".
Now to move the data and views, objects, everything.
I've read up on a variety of migration techniques (oops, I mean "upgradation" LOL) and can follow the steps...
In short, I want to pull everything off of server a (10.2) and put it into production on server b (11.2). There seems to be quit a few options.
1. install 10.2 on my NEW server (server b), move the data over and get everything running, then install 11.2 and have it upgrade the database as part of the installation process. 2. drop the empty tablespace on server b, stop the database on server a, copy the files over from the old to the new home, run DBUA or set the compatibility attribute... 3. run some type of server a to server b utility that can bridge the two over the network. Some type of mirroring technique? 4. run file export scripts on server a, copy files to server b and run various import scripts
I tend to think that option 3 would be the best because both instances are in great health and are running right now. Is there a mechanism that allows the 11.2 instance to see and upgrade from a different server?
I'm trying to migrate an Apex Application from one server to a newer server . My custom app I used the theme from Go Live CheckList samples....
Well, when trying to install that application I get 'Insufficient space to install application ' with a BIG red X... I was able to install other Package Application except for the one I need and now my application errors out because of some shared Themes. At first I thought it was a DB thing so I downgraded back to 10g from 11....but that didn't work... Apex works fine...
Other samples work fine...Version Apex 4.2.2 and Oracle XE 10g...
I want to migrate my database from oracle to postgres.There is a lot of compatibility issues. I heard about the tool ora2pr. have been trying to use it but not able to achieve my goal.Has any one used this tool?
I have to migrate production database version 10gR2 on windows 2003 server to oracle 11gR2 on windows 2008 server...So far i have just installed the oracle software on 64bit windows 2008 server.how to move the data or migrate from old server to new server..
while using top command it shows multiple processes usage.Actually we have 3 databases in the same server.how to find out which database process and user session hogging the cpu resources
Using suppress triggers options in golden gate. I was trying to work on the same but it doesn't seem to work at least for me.
Scenario: Database Version 11.2.0.2 GoldenGate v11 OS Windows
Created two databases on the same server with same schmea idea was to replicate change from one database to other. One of the tables in the source database had trigger(every insertion in the table would cause a row to be inserted into a diff table). if row was inserted in table A it will insert a new row in table B . the same records will pass on target but the trigger defined on table A should not trigger on target as it has already fired on Source .
I tried using suppresstriggers but it doesnt seem to work everytime the trigger is getting fired on target database.
CODEReplicat process replicat repname assumetargetdefs userid gguser@bbb password Oracle dboptions suppresstriggers map x.* ,target x.* (since same schema)
The extract files,pump files and replication are working fine.I also used the dbms_goldengate_auth.grant_admin_privilege for gguser.
Also I noticed when I give the dboptions suppresstriggers replication process doesnt startup with unrecognised word message when i give dboptions suppress triggers the replicat process does start is this the way it should be.i have gone through the docs and it should be supresstriggers.
