I need to migrate data from Mysql database to Oracle11g database.
a) is there any method available to import the all the sqls like table script,constraint scripts,data(insert ) script from Mysql.so that we can apply the sql directly to the oracle schema after making necessary changes(like datatype).
b) Is there any free tool available for the migration.

I`m migrating a mysql 5.0 database to Oracle 11g. I used Oracle's Sql developer and with a workaround i could convert tables, constraints, indexes, some triggers and created sequences.
My question is, what happen with stored procedures and functions, they didn't pass. I've been searching and i found here hey have to be rewritten. Is there any way to convert those objects ? I can't afford to do it manually because the mysql database has almost 400 of them and they aren't small.
1) We get a daily Oracle 11 Dump 2) We only want to import the current changes in a MySQL database .
For this we need:
a) Is there a tool, script or best practices to get only the differences (delta) ? b) How to import an Oracle dump or only teh differences into a MySQL database ?
i tried for 3 days to setup a connection between my oracle database 11.2 (resides on 2003,64 bit Microsoft windows) and a mysql database (resides on 2003,32 bit Microsoft widows).
i used dg4odbc 64 bit which was installed on oracle server, my steps was as follows :
1- configure ODBC driver (MYSQL 3.51 odbc) on oracle server that connect to mysql database and the connection was tested successfully (the name of odbc dsn is DG4ODBC).
2- configure the listener.ora file (which resides on dg4odbc installation path) that contains the following :
4- configure that initdg4odbc.ora file that resides on the dg4odbc installation.
HS_FDS_CONNECT_INFO = DG4ODBC HS_FDS_TRACE_LEVEL = off
5- restart the gateway listener.
6- test DG4ODBC service by tnsping which was successful .when i try to get some data from mysql database by SELECT * FROM MDL_COURSE@DG4ODBC query,the query take some time (15 second !!) and return
ORA-12154: TNS:could not resolve the connect identifier specified
I need to migrate a 500 GB 10.2 database from windows to linux. Of course I found Alejandro Vargas paper on how to do that ("Database Migration From Windows to Linux Using RMAN"). My problem is that the source database will be up again for 7 days and I need to apply all changes made to the source database to the migrated linux database.
Can I just take all redo log files generated from the source database and apply those to the destination database? I might have a problem with a) file conversion and that the redo log are not in sync with the target database (different check points?).I just found that on an exotic website: "The contents of a redo log file depend on a combination of Oracle version, operating system and server architecture. In general redo logs written on one architecture cannot be read on another. There are a few exceptions to this rule. For example, in Oracle 10.2 a redo log written in Linux can be read by a Windows database."
So if this is true, does it also work the other way AND will the database migration from window to linux create a perfect clone of the database where those redo log files actually can be applied to?
We are planning to migate Oracle database from Linux 10gR2 (non-ASM) to Solaris (ASM) and then Oracle upgrade that database from 10gR2 to 11gR2 on Solaris.
I need to migrate database from Windows to Linux. The current size is ~50GB.
Current Env: OS = Windows 2003 DB version = 10.2.0.3
Proposed Env: OS = Linux DB version = 11.2.0.2
Would using datapump be a correct choice for this migration? Also do the step below seem correct?
01. Pre-create tablespaces on target 11g database 02. Export full database of source 10g database 03. Copy dumpfile to Destination Server 04. Grant IMPORT_FULL_DATABASE system privilege to user SYSTEM of target 11g database 05. Import full database to target 11g database
I need to migrate a 10g database into an 11gR2 on same Red Hat Linux platform (although different servers with different versions of Linux). The difference between the two databases however is the SID, the new one has a different SID which means that the datafiles will be named differently (as our datafile names include the SID) otherwise everything else is the same..
I propose to take the following steps:
- install 11gR2 on the new server
- create the 11gR2 database with new SID using DBCA
- full export 10g database
- full import dump file into 11gR2 database.
I however do not have experience of how this will work with respect to the full import where the datafiles are named differently. For example TABLESPACE TEST in the source database has datafile TEST_SOURCE.dbf but the same TABLESPACE TEST in the target database will have datafile TEST_TARGET.dbf.
Will all the data in the source database be correctly imported into the new database?
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 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
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_HOME\DATABASE\INITSID.ORA 6) start dabase in upgrade mode 7) run catpat.sql and util102.sql 8) take backup 9) open database for users

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
If flashback is enable in physical standby database 1. If we failover at 11AM can I flash back NEW primary database to 6 AM ? 2. if I convert physically standby database to snapshot standby database at 11AM , Can I flashback snapshot standby database to 6 AM and do some works on it (DML operations) then converting the snapshot standby database into physical standby database ?
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.
I have installed oracle 11g standard edition one and created both primary and standby database. now i want to know how to switch(convert) primary database to standby database.
