First 150 > ESEutil related MS knowledge base articles for the last year
MODES OF OPERATION:
- Defragmentation: ESEUTIL /d [options]
- Recovery: ESEUTIL /r [options]
- Integrity: ESEUTIL /g
- File Dump: ESEUTIL /m[mode-modifier]
- Repair: ESEUTIL /p Restore: ESEUTIL /c[mode-modifier] [options]
- Checksum: ESEUTIL /k [options]
DEFRAGMENTATION/COMPACTION:
DESCRIPTION: Performs off-line compaction of a database.
SYNTAX: ESEUTIL /d [options]
PARAMETERS: - filename of database to compact
OPTIONS:zero or more of the following switches, separated by a space:
/b - make backup copy under the specified name
/t - set temp. database name default: TEMPDFRG.EDB)
/s - set streaming file name (default: NONE)
/f - set temp. streaming file name (default: TEMPDFRG.STM)
/p - preserve temporary database (i.e., don't instate)
/o - suppress logo
/i - do not defragment streaming file
NOTES:
1) If instating is disabled (i.e., /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: ESEUTIL /r (3 character logfile base name)[options]
OPTIONS: zero or more of the following switches, separated by a space:
/l - location of log files (default: current directory)
/s - location of system files (e.g., checkpoint file) (default: current directory)
/i - ignore mismatched/missing database attachments
/o - suppress logo
INTEGRITY:
DESCRIPTION: Verifies integrity of a database.
SYNTAX: ESEUTIL /g [options]
PARAMETERS: - filename of database to verify
OPTIONS: zero or more of the following switches, separated by a space:
/t - set temp. database name (default:TEMPINTEG704.EDB)
/s - set streaming file name (default: NONE)
/f - set prefix to user for name of report files (default: database.integ.raw)
/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.
FILE DUMP:
DESCRIPTION: Generates formatted output of various database file types.
SYNTAX: ESEUTIL /m [options]
PARAMETERS:
- an optional letter designating the type of file dump to perform. Valid values are:
h - dump database header (default)
k - dump checkpoint file
l - dump log file or set of logs
m - dump meta-data
s - dump space usage
- name of file to dump. The type of the specified file should match the dump type being requested. (eg. if using /mh, then must be the name of a database.)
OPTIONS: zero or more of the following switches, separated by a space:
/v - verbose
/s - set streaming file name (default: NONE)
/t - dump nodes for a certain table
REPAIR:
DESCRIPTION: Repairs a corrupted or damaged database.
SYNTAX: ESEUTIL /p [options]
PARAMETERS: - filename of database to repair
OPTIONS: zero or more of the following switches, separated by a space:
/s - set streaming file name (default: NONE)
/t - set temp. database name (default: TEMPREPAIR*.EDB)
/f - set prefix to use for name of report files (default: .integ.raw)
/i - bypass the database and streaming file mismatch error
/g - run integrity check before repairing
/createstm - create empty streaming file if the file is missing
/o - suppress logo
NOTES:
1) Repair does not run database recovery. If a database is in a "Dirty Shutdown" state it is strongly recommended that before proceeding with repair, recovery is first run to properly complete database operations for the previous shutdown.
2) The /i option ignores the signature mismatch error in the check phase if the database and streaming file do not match each other. The database and streaming file will receive new signatures in the repair phase. Without using this option, repair will terminate immediately once the database and streaming file mismatch error occurs.
3) The /g option pauses the utility for user input before repair is performed if corruption is detected. This option overrides /createstm and /o options.
4) The /createstm option is irreversible. Once you start the repair process a new streaming file will be created. Any streaming file that existed before the repair will no longer work with this database.
RESTORE:
DESCRIPTION: Restore information and completion.
SYNTAX: ESEUTIL /c[mode-modifier] [options]
PARAMETERS:
[mode-modifier] - a letter designating the type of operation to be done
m - dump Restore.Env
c - start recovery for a Restore.Env
- directory of the restore (Restore.Env location)
OPTIONS: zero or more of the following switches, separated by a space:
/t - name of the instance where the play forward
log file (default: from backup)
If is blank, don't play forward
any log files.
/k - preserves the log files used for recovery
/o - suppress logo
CHECKSUM:
DESCRIPTION: Verifies the checksums of a database.
SYNTAX: ESEUTIL /k [options]
PARAMETERS: - filename of database to verify
OPTIONS: zero or more of the following switches, separated by a space:
/s - set streaming file name (default: NONE)
/t - set temp. database name (default: TEMPCHKSUM*.EDB)
/e - don't checksum database file
/i - don't checksum streaming file
/o - suppress logo
NOTES:
1) The operation does not run database recovery. If
the database file (.edb) is in an inconsistent state
it is not possible to verify checksums in the
streaming file (.stm).
