DEFRAGMENTATION/COMPACTION:
DESCRIPTION: Performs off-line compaction of a database.
SYNTAX: EDBUTIL /d <database name> [options]
PARAMETERS: <database name> - filename of database to compact,
or one of /ispriv, /ispub, or /ds (see
NOTES below)
OPTIONS: zero or more of the following switches, separated by a
space:
/l<path> - location of log files (default: current
directory)
/s<path> - location of system files (eg. checkpoint file)
(default: current directory)
/r - repair database while defragmenting
/b<db> - make backup copy under the specified name
/t<db> - set temp. database name (default:
TEMPDFRG.EDB)
Note: Do not put a space between the switch
and the database name.
/p - preserve temporary database (ie. don't
instate)
/n - dump defragmentation information to
DFRGINFO.TXT
/o - suppress logo
NOTES: 1) The switches /ispriv, /ispub, and /ds use the Registry
to automatically set the database name, log file path,
and system file path for the appropriate Exchange
store.
2) Before defragmentation begins, soft recovery is always
performed to ensure the database is in a consistent
state.
3) If instating is disabled (ie. /p), the original
database is preserved uncompacted, and the temporary
database will contain the defragmented version of the
database.
RECOVERY:
DESCRIPTION: Performs recovery, bringing all databases to a
consistent state.
SYNTAX: EDBUTIL /r [options]
OPTIONS: zero or more of the following switches, separated by a
space:
/is or /ds - see NOTES below
/l<path> - location of log files
(default: current directory)
/s<path> - location of system files (eg. checkpoint
file)
(default: current directory)
/o - suppress logo
NOTES: 1) The special switches /is and /ds use the Registry to
automatically set the log file path and system file
path for recovery of the appropriate Exchange
store(s).
CONSISTENCY:
DESCRIPTION: Verifies consistency of a database.
SYNTAX: EDBUTIL /c <database name> [options]
PARAMETERS: <database name> - filename of database to verify, or
one of /ispriv, /ispub, or /ds
(see NOTES below)
OPTIONS: zero or more of the following switches, separated by a
space:
/a - check all nodes, including deleted ones
/k - generate key usage statistics
/p - generate page usage information
/t<name> - performs a check on the specified table only
(default: checks all tables in the database)
Note: Do not put a space between the switch
and the database name.
/o - suppress logo
NOTES: 1) The consistency-checker performs no recovery and
always assumes that the database is in a consistent
state, returning an error if this is not the case.
2) The special switches /ispriv, /ispub, and /ds use the
Registry to automatically set the database name for
the appropriate Exchange store.
UPGRADE:
DESCRIPTION: Upgrades a database (created using a previous
release of Microsoft(R) Exchange Server) to the
current version.
SYNTAX: EDBUTIL /u <database name> /d<previous .DLL> [options]
PARAMETERS: <database name> - filename of the database to
upgrade.
/d<previous .DLL> - pathed filename of the .DLL that came
with the release of Microsoft(R)
Exchange Server from which you're
upgrading.
OPTIONS: zero or more of the following switches, separated by a
space:
/b<db> - make backup copy under the specified name
/t<db> - set temporary database name (default:
TEMPUPGD.EDB)
Note: Do not put a space between the switch
and the database name.
/p - preserve temporary database (ie. don't instate)
/n - dump upgrade information to UPGDINFO.TXT
/o - suppress logo
NOTES: 1) This utility should only be used to upgrade a database
after an internal database format change has taken
place.
If necessary, this will usually only coincide with the
release of a major, new revision of Microsoft(R)
Exchange Server.
2) Before upgrading, the database should be in a
consistent state. An error will be returned if
otherwise.
3) If instating is disabled (ie. /p), the original
database is preserved unchanged, and the temporary
database will contain the upgraded version of the
database.
FILE DUMP:
DESCRIPTION: Generates formatted output of various database file
types.
SYNTAX: EDBUTIL /m[mode-modifier] <filename>
PARAMETERS: [mode-modifier] - an optional letter designating the
type of file dump to perform. Valid values are:
h - dump database header (default)
k - dump checkpoint file
<filename> - name of file to dump. The type of the
specified file should match the dump type
being requested (eg. if using /mh, then
<filename> must be the name of a database).
