A Green and Click to Run DUL data Unloader Tool


PRM-DUL Data Unloader (ParnassusData Recovery Manager) is developed by JAVA, which can extract data from
oracle datafile without Oracle RDBMS software/instance. Since PRM walk around UNDO, little of data, which is transactional, can be missed.


PRM-DUL Data Unloader Can Save Your Data Even Oracle is Damaged


Sometimes, Oracle DB is damaged, but most of data block is find. With PRM, it can be extracted row by row. If the block is damaged badly, PRM will dump log.

PRM Can Extract TABLE/CLUSTER Data


PRM-DUL data unloader can extract TABLE/CLUSTER data. PRM is designed not to extract trigger, store procedure or view. Of course, PRM can save the SOURCE$. PRM can not recover index data , since it does not have meaning on this, unless it is IOT index.

A Revolutionary DataBridge Feature


Why use DataBridge?
  • Traditional unload+sqlldr means a copy of data needs to be saved as flat file on filesystem first, data has to be loaded into Unicode text file and then inserted into destination database by sqlldr, this will take double storage and double time.
  • DataBridge can extract data from source DB and export to destination DB without any intermediary.
  • Once the data arrived destination DB, user can begin to validate them.
  • If source and destination database located on different servers, then read/write IO will be balanced on two servers ,MTTR will be saved.
  • If DataBridge is used in truncated table recovery, it is very convenient that truncated data can be exported back to problem database directly.
  • DataBridge is very simple and convenient.
