Schema Export in Oracle XE

Oracle XE makes it really easy to export your database schema.

Go to the Oracle XE web interface (running on http://localhost:8080/apex/ by default), and login with your username (not the system user).

Choose Utilities -> Generate DDL. Check the tables for which you want to export the DDL commands, and you are good to go.

To run Tora, add the following to your profile file


And create a tnsnames.ora file in your ORACLE_HOME.
This file lists your Oracle services in the following format –



       (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = = 1521)))



(Re: Error connecting to an Oracle DB)

If Tora is still not connecting to oracle, try exporting TNS_ADMIN environment variable, pointing to the location of tnsnames.ora file –

export TNS_ADMIN=/usr/lib/oracle/xe/app/oracle/product/10.2.0/client/
