(Formerly Btrieve Administrator's Recovery ToolKit (BART))

Although Pervasive has trumpeted the Btrieve and Pervasive.SQL databases as not needing a database administrator (i.e. zero DBA), there remains some call for people extremely knowledgeable about the database and the database files and structures, especially when the operating system decides to mangle a data file. (Although everyone knows that MS Windows never crashes, its "features" sometimes cause some consternation.)

Designed for the Btrieve Database Administrator who needs to manually recover data from a database file or determine the cause of a failure from time to time, these tools are used internally by Goldstar Software as part of our "Btrieve File Forensics" -- the study of corrupted files in search of a root cause. Previous versions of our BART toolkit were released with no or limited documentation. The new Pervasive Data File Recovery Toolkit is now shipping with a complete manual that covers all aspects of the file recovery process.

Features of the Pervasive Data File Recovery Toolkit include the following:

  • Copies of "standard" data analysis and recovery tools from Pervasive Software, in one place.
    • BCheck and BUTIL for file analysis
    • BClean, ByteChg, and BUTIL for file recovery
  • Copies of Jim Kyle's DataSave and DSave3a file recovery tools, in one place.
  • Copies of "advanced" 32-bit data analysis and recovery tools from Goldstar Software -- some now available for the first time ever!
    • Breaker & Maker: Splits large files into smaller pieces for easier manipulation
    • BtrvInfo & ListStat: Better BUTIL -STAT analysis
    • DXUtil: A Better BUTIL with some advanced features for recovery
    • FindBad: Locates the bad "spot" in a file
    • FindUNF: Finds a specific record in a UNF file
    • GREP32: A general purpose search tool
    • GSRecover: Our most powerful data recovery tool
    • KeyCheck: Checks files and indices for corruption
    • KeyData: Reports on internal file page and key statistics
    • KillPre: Gets rid of Btrieve 5.x PRE files
    • ListDPg: Finds and renumbers data pages in a data file
    • LPLookup & PPLookup: Data file analysis tools for manual efforts
    • MoveRecs: Data migration tool

    • ReadFile: A file viewer that works from the command line
    • VarCheck: Analysis tool for variable-length files

  • Sample files in various versions to show different internal constructs
  • Damaged files with various types of corruption to show how to fix each type
  • Trial downloads of Pervasive PSQL v11/v12 and Pervasive.SQL V8 to allow you to work with files from the 5.x format all the way through the current 9.5 format
  • A fully-licensed deployment engine of Btrieve 6.15.430, with the needed patches to address the infamous "PATFix" bug
  • Trial downloads of other useful third-party software, including Hex Workshop, UltraEdit, BTSearch 2008, and many more
