SUMMARY

The Jetutils.exe file contains the "Understanding Microsoft Jet Locking" white paper, the LDBView utility, the DBLock utility, and the Msldbusr.dll.

The white paper introduces you to the Microsoft Jet Database Engine versions 2.x and 3.x locking techniques so that you can apply the information to coding and debugging techniques when developing multi-user applications.

The LDBView utility is used to accomplish the following tasks:

  • Discover which users have been connected to the database and which users are currently connected to the database.
  • Discover the values of the commit bytes in the DBH (database header page).
  • Determine which user or users have left the database in a suspect state.

LDBView is a 32-bit single .exe utility that can run under either Windows 95 or Windows NT, and can view both Microsoft Jet 2.x and Microsoft Jet 3.x databases.

The DBLock utility determines which types of locks Microsoft Jet is placing, which page types are being locked, and which tables are associated with those pages. DBLock is a Visual Basic 4.0/5.0 32-bit utility that runs under either Windows 95 or Windows NT and can work against both Microsoft Jet 2.x and Microsoft Jet 3.x databases.

The Msldbusr.dll is a 32-bit DLL that enables you to retrieve one of the most sought-after pieces of information: a list of users connected to the database. Because this is a 32-bit DLL, it will only work with 32-bit products running on Windows 95 or Windows NT. It retrieves information for both Microsoft Jet 2.x and Microsoft Jet 3.x databases.
