Migrate MySQL 5.0 Objects To Oracle 11g

Jan 23, 2013

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.

Oracle And MySQL Database - Could Not Resolve Connect Identifier Specified

Jun 2, 2011

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 :

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = xxxxxxxxxxxx)(PORT = 1511))

[code]....

3- configure the tnsnames.ora file (which resides on oracle database path) that contains the follwoing :

DG4ODBC =
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=xxxxxxxxxxxx)(PORT=1521))
(CONNECT_DATA = ( SERVICE_NAME = DG4ODBC ))
(HS=OK)
)

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

Migrate Database To Linux And Apply Inc Changes Afterwards

Mar 3, 2012

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?

Upgrade :: Migrate Database From Windows To Linux?

May 6, 2013

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

Export/Import/SQL Loader :: Migrate Database Into Different SID

Jul 19, 2012

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?

Data Guard :: Apply Patches On Oracle Database With Logical Standby Database?

Apr 22, 2011

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
