What is OraDB DUMP Viewer?
OraDB DUMP Viewer is a tool for viewing Oracle EXP(legacy Export) and EXPDP(DataPump) format .dmp files without requiring an Oracle database or Oracle Client installation. It features a high-speed parsing engine using a C native DLL, instantly retrieving table lists and loading only the necessary tables on demand.
Key Features
🔍 Oracle-Free DMP Parsing
Analyze and view schema, table, and data within .dmp files without installing an Oracle database or Client.
🌳 Schema and Table Tree View
Displays schemas within DMP files as hierarchical trees. Quickly grasp names, owners, and row counts from the table list, and preview data with a double-click.
🔎 Advanced Search Capabilities
Instantly find target data using SSMS-like compound condition searches combining 12 operators (including, prefix/suffix match, null check, etc.) with AND/OR logic.
📊 Large Data Support
Smoothly browse datasets with millions of rows using paging. A progress bar displays real-time analysis status (processing speed, remaining time, estimated completion).
🪟 MDI Multi-Window
Open multiple DMP files or table previews simultaneously. Freely arrange layouts—stacked, side-by-side, or icon-aligned—to work efficiently.
