Compacts a Windows Internet Name Service (WINS) or Dynamic Host Configuration Protocol (DHCP) database. We recommend you compact the WINS database whenever it approaches 30 MB.
Jetpack.exe compacts the database by:
-
Copying the database information to a temporary database file.
-
Deleting the original database file, either WINS or DHCP.
-
Renames the temporary database files to the original filename.
jetpack.exe <database_name> <temp_database_name>
Parameter | Description |
---|---|
<database_name> |
Specifies the name of the original database file. |
<temp_database_name> |
Specifies the name of the temporary database file to be created by jetpack.exe. Note: This temporary file is removed when the compact process is complete. For this command to work properly, you must make sure your temp file name is unique and that a file with that name doesn't already exist. |
/? | Displays help at the command prompt. |
To compact the WINS database, where Tmp.mdb is a temporary database and Wins.mdb is the WINS database, type:
cd %SYSTEMROOT%\SYSTEM32\WINS
NET STOP WINS
jetpack Wins.mdb Tmp.mdb
NET start WINS
To compact the DHCP database, where Tmp.mdb is a temporary database and Dhcp.mdb is the DHCP database, type:
cd %SYSTEMROOT%\SYSTEM32\DHCP
NET STOP DHCPSERVER
jetpack Dhcp.mdb Tmp.mdb
NET start DHCPSERVER
