oracle-schema-dumper

Tool for exporting all objects in a database schema to a set of files.

Presentation

This tool allows you to export the complete PL/SQL code and database objects within an Oracle schema to a set of files. The files are one for each Oracle object (table, view, trigger, procedure, function, type, package, etc.). These files can be used for off-line inspection, code versioning, etc. The script is written in Python and requires the cx_Oracle package to work. A Javascript version for Windows is also provided, it uses OLE DB for database connectivity.

The approach taken is somewhat different from the traditional Oracle tools for creating a database dump, these are aimed at cloning or backing up a schema both in terms of structure and data, thus treat the dump file as a black box.

Usage

Define in a configuration file the details of the schemas than need to be downloaded. The format is a JSON array of objects as the following.

[
  { "active": true, "schema": "scott", "pwd": "tiger", "tns": "127.0.0.1/orcl", "folder_name": "dump_scott", "comment": "Sample dump for the Scott schema" }
, { "active": true, "schema": "prod", "pwd": "Prod123", "tns": "127.0.0.1/orcl", "folder_name": "dump_prod", "comment": "Sample dump for the production schema" }
]

Python:

dump_ora_schema.py --conf my_schemas.json --output_root_folder C:/Oracle_dumps/py

JavaScript:

For a 32-bit Oracle client installation.

%SystemRoot%\SysWoW64\cscript.exe dump_ora_schema.js --conf schemas_js.json --output_root_folder C:/Oracle_dumps/js

For a 64-bit Oracle client installation (or for a 32-bit Windows version).

%SystemRoot%\System32\cscript.exe dump_ora_schema.js --conf schemas_js.json --output_root_folder C:/Oracle_dumps/js
