Recipe 6.7. Mounting a Database

Problem

You need to mount a database so users can connect to it.

Solution

Using a graphical user interface

  1. Launch the Exchange System Manager (Exchange System Manager.msc).

  2. In the left pane, expand the appropriate Administrative Groups container, and then expand the Servers container.

  3. Expand the server that contains the target database, then expand the parent SG.

  4. Right-click the target database and select Mount Store.

  5. When the store has been remounted, ESM will display a dialog telling you so; click OK to dismiss it.

Using VBScript
' This code mounts the specified mailbox database ' ------ SCRIPT CONFIGURATION ------  strServerName = "<SERVERNAME>"   ' e.g., "BATMAN"      strMDBName = "<databaseName>"        ' e.g., "Mailbox Store (SpiffyDatabaseName)"  ' ------ END CONFIGURATION --------- Set theServer = CreateObject("CDOEXM.ExchangeServer") Set theMDB = CreateObject("CDOEXM.MailboxStoreDB") theServer.DataSource.Open strServerName arrSG = theServer.StorageGroups theFirstSG = arrSG(0) strURL = "LDAP://" & theServer.DirectoryServer & "/cn=" & strMDBName & "," & theFirstSG theMDB.DataSource.Open strURL theMDB.Mount WScript.Echo "Database mounted."

Discussion

You must mount a database before users can connect to it, or before you attempt to back it up using the ESE backup APIs discussed in Chapter 11. When you mount a database, ESE performs a quick integrity check on the database header; after the database is mounted, if there are pending transaction logs, they will be played back. This can affect the speed of mounting the database (although, interestingly, dismounting a database always takes roughly the same amount of time, no matter how large it is). If Store.exe is able to mount the database, it will post event 9523 to the application event log.

Using VBScript

The code only works with mailbox databases because it uses the MailboxStoreDB object from CDOEXM. To make it work with public databases, you need to modify it to use the PublicStoreDB object instead.
