XFOR: List of Default Jet Database Files in DXADATA

ID: Q193378

The information in this article applies to:
  • Microsoft Exchange Server, versions 4.0, 5.0, 5.5

SUMMARY

After the Microsoft Exchange Directory Synchronization service (DXA) is started for the first time, several files appear in the exchsrvr\dxadata subdirectory. These files are Jet database files related to directory synchronization between Exchange Server and Microsoft Mail servers.


MORE INFORMATION

The following files are Jet database components for directory synchronization:

  • Xdir.edb. Jet database. Includes mappings list of all transactions that have been sent by the DXA.


  • Edb.chk. External checkpoint file that marks the position in the log files at which the database is in a consistent state.


  • Edb.log. Write-ahead transaction log for directory synchronization transaction.


  • Temp.edb. Log file used to store transactions that are in progress. Temp.edb is also used for some transient storage during online compaction.


  • Res1.log and Res2.log. Reserved disk space, so that if the database or log file hard disk drive is full, Exchange Server can still be cleanly stopped.


NOTE: The Res1.log and Res2.log files are created with the size of 1,024 KB instead of 5,120 KB, which is the size for directory and information store databases' log files.
