What you need is the Informix Dynamic Server JDBC Driver, version 1.4 JAR file, ifxjdbc.jar.
This driver is shipped with the Informix Dynamic Server software. I am not sure you can download it freely.

DB Migration from MYSQL to ORACLE Using Offline Capture

Hi
Am doing a database migration from MySQL to Oracle using SQL Developer (version 2.1.1.64). So far, I've successfully captured the MySQL database and converted it to the Oracle Model. However, when generating offline scripts to create the converted model schema into Oracle DDL scripts it managed to generate SQL to create: 1) User 2) Sequences 3) Tables 4) Triggers and 5) constraints.
It has created the SQL to add the primary key constraints and index constraints. Although it did the foreign key constraints in the SQL, the foreign key constraints seems to have missed the cascading options for the foreign key constraint. I.e. theres no reference of whether the foreign key constraint will restrict on delete or cascade etc.
We have a foreign keys in the MySql database that have different cascading options and these have not being ported over into the migration SQL. Therefore, all the foreign keys generated in the SQL by default are cascade to restrict on delete.
Does 'Generate Oracle DDL' not take into account a foreign key's on delete cascading option?
Any help or information would be greatly appreciated.
Thanks

Hello,
that reminded me for the following thread:
Migration Microsoft SQL Sever 2005 to Oracle 11g cascade on delete problem
That is a similar issue, isn't it?
I opened a bug for that, and it will be fixed in SQL Developer 3.1 (not in any 3.0 Early Adopter version). If you hit the same issue, there is no other way then using the workaround as used in the mentioned thread.

Problem while migrating from Sybase to Oracle using Quick Migrate

Hi,
For SQL Developer version 2.1, while migrating from sybase to oracle, Using Quick migrate, during data move step, for the rows having ''(Blank) values in TEXT data type in SYBASE, which is convertd to CLOB in Oracle, the migration for that table terminates at that row.
However, NULL values in Sybase TEXT data type are successfully inserted in Oracle CLOB.
How can we overcome this?

reproduced and see exception in console, bug logged.

Migrating from Progress to Oracle

Hi,
Wonder if someone's migrated from Progress to Oracle. What tools are available ? what are the constraints/pitfalls/limitations/restrictions ? I need to understand the overall migration process (not having done one yet). What are the tools ? what the procedural steps specifically to go from Progress to Oracle ?
If someone has done such project, I can use some highlights (if you can share your knowledge/experince).
Much appreciate any response.
Rohit.

Here is a bit of an update gathered from my own research on this issue. Hopefully, it can help someone with the same requirement as mine.
1. Oracle Migration WorkBench does NOT have support for Progress yet and according to Oracle sales, it may never be made available. Thus MWB is not an option.
2. Oracle Migration Toolkit is a possibility as it does have support going from Progress 6.x and 7.x to Oracle 7. The limitation here is that you can only go up to Oracle 7 from Progress 6.x or 7.x. In this case, I can migrate to Oracle 7 and then once all is well, upgrade Oracle to 8i or whatever.
3. The last option is, if migration toolkit does not work out, go the traditional route which is to export/extract Progress out into flat files and then load into Oracle using SQL Loader.

Move database from server running Oracle 11G to server running Oracle 12c

I'm trying to find out the easiest way to migrate a database from a server running Oracle 11G to a server running Oracle 12c. I have tried using RMAN's duplicate database command but have run into far too many issues when trying to setup both servers before running the duplicate command. If someone could provide some clear guidance on configuring both servers for the RMAN Duplicate command then that would be great. The other thing I have tried is performing a cold backup of all the files for the database (control files, data files, etc.). Copying them to the new server and then recreating the control file to include the correct location and names for the datafiles and redologs. After recreating the control file the database will not start up. I'm suspecting this is due to the version differences. If you can provide me clear (ie. migration for dummies) instruction for getting either of these methods to work it would be greatly appreciated. I'm also open to any other method you can think of to achieve what I'm trying to accomplish. Thanks, Paul Noyes

Migrating Sybase code to Oracle 11g

Hi All,
We have to migrate Sybase code to Oracle 11g.
When we are doing a SELECT .. INTO in Sybase , even if the query is returning more than 1 row , sybase selects 1 of the rows and populates the variables.
But while migrating this code to oracle, we are getting TOO_MANY_ROWS Exception.
We need to migrate the code from SYBASE to ORACLE without disturbing the logic.
Can someone please tell me the logic applied by SYBASE to pick up the record?
And if someone has faced this issue, then what can be done to resolve this.
Regards,
Riddhisha Khamesra

The result 3 is the last entered record (not the amount of records..).
So the first approach to write a dummy procedure that will select all records in Oracle like:
CREATE OR REPLACE PROCEDURE last_record
v_arg1 OUT NUMBER
AS
BEGIN
SELECT col1
INTO v_arg1
FROM tt_tmp ;
END;
and hopefully returns only the last record will fail with:
SQL> variable outvar number
SQL> exec last_record (:outvar)
BEGIN last_record (:outvar); END;
ERROR at line 1:
ORA-01422: exact fetch returns more than requested number of rows
ORA-06512: at "SYSTEM.LAST_RECORD", line 9
ORA-06512: at line 1
One possible approach to get the last (and only the last) record that was entered into the table is to use rownum:
The select might look like "select col1 from (select col1, rownum from tt_tmp order by rownum desc) where rownum=1;"
So the procedure can be coded as:
CREATE OR REPLACE PROCEDURE last_record
v_arg1 OUT NUMBER
AS
BEGIN
SELECT col1
INTO v_arg1
from (select col1, rownum from tt_tmp order by rownum desc) where rownum=1;
END;
Now calling it in SQL*Plus:
SQL> variable outvar number
SQL> exec last_record (:outvar)
PL/SQL procedure successfully completed.
SQL> print :outvar
OUTVAR
7
The value 7 is the last record I've inserted into my tt_tmp table:
SQL> select * from tt_tmp;
COL1 COL2
1 1
2 2
8 8
7 7

Migrating MySQL database to Oracle 11g RAC

Hi,
I would like to migrate an entire database from MySQL to my new Oracle 11g RAC. How do I do it?

Hi Turloch,
I was able to configure SQLDeveloper to connect to Oracle and MySQL.
I am having a hard time migrating data from mysql maybe due to table size. I got mysql tables with more than 20M and the PC am running the sqldeveloper is running out of memory every time I try to migrate the tables.
Can you share some experience migrating from MySQL to Oracle?
Thank You.

Sqldeveloper capturing null DB during Migration Sysbase 15 to Oracle 11g.

I am doing offline migration from Sybase to Oracle using SQLdeveloper 3.0.02 . I have performed below steps:
1) Create a user (without CREATE ROLE, CREATE USER, DROP ANY SEQUENCE, DROP ANY TABLE, DROP ANY TRIGGER, DROP USER, DROP ANY ROLE, GRANT ANY ROLE privileges due to security reasons I can't have these privileges. This user have all other privileges suggest as per Oracle docs)
2) Create a migration repository
3) Made a connection and associate the migration repository to it.
4) Generate the offline Sybase capture files using sqldeveloper and generate the dat files having Sybase structure.
5) Tool -> migration -> migrate -> following the wizard instructions I start the migration.
Now the message window showing me 1) capturing connections 2) capturing catalogs and then directly migration is successful. Finally there is no error message.
I have checked the migration project navigation window and found that sql developer has captured the null database.
I checked the migration repository tables and found that only MD_CONNECTIONS, MD_CATALOGS and MD_DERIVATIVE tables are populated.
Could you please suggest me why SQL developer captured the null database. ( No Sybase database objects are captured from Sybase15.ocp file)
ASAP reply would be appreciated.
Regards
Abdul

Hi,
At that time SQL developer was not able to capture the connection details. The error msg was "Capturing connection failed". So we downloaded the sybase jtds driver and recaptured ocp files from sybase and run the migration again...this time capture connection is successful and capturing of cataloge is successful and after that sql developer can't able to capture any sybase db objects from sybase15.ocp
We going to upgrade sql developer to latest version and will try it again.

Migrating from Sybase to Oracle

Hi!
Can someone tell me, how to migrate from Sybase to Oracle.
Thank U.

Hi,
You don't say if you have used the SQL*Developer migration workbench for the migration so far.
This has a feature for transferring data offline which should do what you want.
Have a look at the documentation linked from -
http://www.oracle.com/technology/tech/migration//workbench/index_sqldev_omwb.html
or at -
http://download.oracle.com/docs/cd/E12151_01/index.htm
