I am using Oracle 12c to test migration from Oracle to PostgreSQL. I am using windows OS. I have copied ojdbc7.jar file under lib folder of "EnterpriseDB-MigrationToolkit"

I am getting following error:

Pretty sure you're going to have to look in the logs as suggested by the message before anyone can help.

Oops, missed the line about Oracle driver class not being found.

I don't know EnterpriseDb, but it seems highly suspect that you're putting an jdbc jar file into the enterprise manager
directorystructure rather than in a folder in a standard location for jar files, in other words something on your java
CLASSPATH--which,unfortunately, I have no idea what that would be for Windows OS.

Hi Sandeep,

As from the error log it seems that you haven't added oracle-jdbc driver to the classpath. You can do so by running command something like --
export CLASSPATH= "$CLASSPATH:path/to/jar/file"

Hope this helps.

Hi Sandeep,

First you need to copy ojdbc7.jar in proper location, then edit the toolkit.properties file which is located in etc folder of installation of MTK.

Example:

SRC_DB_URL=jdbc:oracle:thin:@localhost:1521:xe
SRC_DB_USER=hr
SRC_DB_PASSWORD=hr

TARGET_DB_URL=jdbc:postgresql://localhost:5432/postgres
TARGET_DB_USER=postgres
TARGET_DB_PASSWORD=postgres

After saving the toolkit.properties file run runMTK.bat from cmd as follows:

runMTK.bat -sourcedbtype source_database_name -targetdbtype target_database_name schema_name

Example:

runMTK.bat -sourcedbtype oracle -targetdbtype postgres public

I hope this will solve your problem.

I have copied ojdbc7.jar under "C:\Program Files (x86)\Java\jre7\lib" and
 
SET CLASSPATH="C:\Program Files (x86)\Java\jre7\lib"
still no luck.

Hi Sandeep,

The driver copying location is wrong

Copy driver to C:\Program Files (x86)\Java\jre7\lib\ext\ location

copy both oracle & postgresql drivers under above location.

I hope now this time it will solve your porblem.
