Extensible Storage Engine software or Eseutil is an integrated Microsoft application. It enables change and IT directors to restore inconsistent, corrupt or damaged alternate databases (EDB). The Eseutil permits administrators to efficaciously cope with trade database corruption troubles and restore the database. It additionally restores the person’s mailboxes when the backup isn’t always to be had or turns obsolete.
Typically the application fails to restore a corrupt or broken alternate database or defragment a database because of permission issues, insufficient garage area, or obstacles. In such instances, you could encounter numerous Eseutil mistakes. In this text, we’ve got mentioned a few common Eseutil mistakes and the answers to resolve them.
Eseutil database recuperation modes
- Advertisement -
Right here are the two special Eseutil database recovery modes to restore corrupt databases:
1. Gentle recuperation
- Brings the database returned from a grimy Shutdown country to a consistent kingdom or a clean shutdown kingdom.
- In the database, the transaction logs are replayed.
2. Hard recovery
- This is used when transaction logs are lacking, deleted, or unavailable.
- It enables the recovery of an inconsistent or corrupt change database from a grimy Shutdown country to a clean Shutdown country by means of purging the database’s irrecoverable mailboxes or mail gadgets.
- Whilst you run smooth recuperation or tough restoration on a corrupt or inconsistent database, you could come upon one of the several Eseutil mistakes.
Not unusual Eseutil mistakes listing
1. Eseutil errors 1003
Here is the mistake 1003 or JET_errInvalidParameter -1003 appears when you run gentle restoration on the corrupt or inconsistent database copy. The error reads as follows:
starting up healing mode...
Logfile base name: C:program FilesMicrosoftExchange ServerV15MailboxMailbox Databasee00
Log documents: C:application FilesMicrosoftExchange ServerV15MailboxMailbox Database
System files: C:application FilesMicrosoftExchange ServerV15Mailbox
Database directory: C:software FilesMicrosoftExchange ServerV15MailboxMailbox Database
Operation terminated with error -1003 (JET_errInvalidParameter, Invalid API parameter) after x.Xx seconds.
The error code 1003 appears because of the subsequent motives:
- Low storage: at some stage in database restore, you need to have at the least 110% loose garage of the database size to shop the temp database report throughout the repair method. If the disk storage is low, the application may additionally fail to create the temporary reproduction for database repair and show the error 1003.
- IPV6: the mistake may additionally appear if the IPV6 isn’t always enabled on the network adapter.
2. Eseutil /d mistakes -1808
The mistake code 1808 or JET_errDiskFull -1808 is a disk area-related Eseutil mistake that forestalls the software from defragmenting the database file due to low garage space. It seems when the application fails to defragment the trade database report after a restore or healing session or while performing everyday database maintenance responsibilities.
Here is the subsequent difficulty:
Operation terminated with errors -1808 (Jet_err DiskFull, no area left on Disk) after x.Xx seconds
3. Eseutil /r Checksum blunders 1018 on the Database page
The checksum JET_errReadVerifyFailure -1018 or checksum blunders on the database page appear whilst a consistency takes a look at (Eseutil /g) or trade database recovery fails. The error is due to the corrupted database. Database corruption happens because of hardware-related problems or failure.
The error message reads as follows:
Operation terminated with errors -1018 /jet_errreadverifyfailure, checksum="" blunders="" after x.Xx seconds
4. Eseutil awful Checksum errors are counted
The user or administrator runs the checksum test of the usage of the Eseutil /ok parameter. Terrible checksum counts when displayed indicate a trouble with the database content or report.
This command output is displayed if the database or the STM document you are checking is broken or corrupt.As follows:
XXXX pages seen
XX bad checksums
XXXX uninitialized pages
The operation changed into completed successfully in x.Xxx seconds.
Besides awful checksums, some other related checksum mistakes can also appear – “Eseutil Checksum Failed with Microsoft Eseutil return mistakes Code -1.”
In one of these case, strive smooth restoration. If it fails, perform hard healing to repair the database. Then run an integrity test to test the database for awful checksums or checksum errors. Ensure the terrible checksum be counted is 0.
5. Eseutil /r Terminated with blunders -566
Whilst the dbtime on a database web page is smaller than the dbtime before within the document, the gentle restoration fails with the mistake code -566 or JET_errDbTimeTooOld -566.
The error message reads as follows:
starting up restoration mode...
Logfile base name: e01
Database listing: I:program FilesMicrosoftExchange ServerVxxMailboxMBXDB01MBXDB01.Edb
Acting gentle recuperation...
Operation terminated with blunders -541 (JET_errLogFileSizeMismatch, real log file size does not in shape JET_pa
6. Eseutil /r errors 1119
The mistake 1119 or JET_errReadLostFlushVerifyFailure -1119 is displayed whilst the database web page read from the garage media had a preceding write no longer represented at the database page.
The error is prompted whilst the force has document machine problems or the storage media has failed. The whole mistakes message reads as follows:
Operation terminated with errors -1119 (JET_errReadLostFlushVerifyFailure, The database web page study from disk
7. Eseutil Jet errors LV Corrupted Jet error -1526
JET_errLVCorrupted -1526 is an Eseutil error that happens when a person tries to mount the database but fails due to a corrupt or damaged log file. It happens while the Eseutil detects corruption in a long-fee tree.
8. Eseutil /d blunders 555
The JET_errGivenLogFileHasBadSignature -555 is an Eseutil error that shows a problem with the repair log file. The log file is both damaged or has a horrific signature. It appears when the person runs Eseutil /d command to defragment and change database records.
In this sort of case, you could carry out soft recovery (eseutil /r ) at the database to restore it.
9. Eseutil Failure Writing to Log record
the mistake -501 JET_errLogFileCorrupt or failure writing to log report happens when hardware corrupts I/O at writing or lost the flush main to an risky log. This could occur whilst the difficult drive, controller, or hardware stops responding to the commands, or there’s a war resulting from programs, together with antivirus that can lock the active listing log documents.
10. The way to prevent and clear up Eseutil errors?
Earlier than the use of Eseutil to recover or defragment the change database, you have to check and meet the stipulations required to run the Eseutil.
To make sure Eseutil does no longer fail or result in the errors mentioned above, check the subsequent:
- The person account used to execute Eseutil instructions have to be an exchange administrator.
- The trade database file ought to be offline and not set up at the server.
- The drive wherein the database report is saved ought to have 110% unfastened disk space than the database record size. You can pass big files or folders that are not required to a specific volume or outside drive to loose up space.
- Test the garage media for any disk errors and attach them the usage of CHKDSK.
- Take a look at and allow IPv6 to your community adapter.
After pleasant the stipulations the mistakes still seem or Eseutil fails to get better the database, it may be because of one or greater of the subsequent motives:
- The database is seriously corrupt or broken, beyond the abilties of Eseutil.
- The STM report is unavailable or does now not match the alternate database you are trying to restore.
Short answers to solve Eseutil Jet Database mistakes
- Restart the server and attempt once more. This may provide you get entry to if due to brief hardware or software program-related problem.
- There’s a battle between the apps that might be locking the documents required to carry out certain operations. As an instance, antivirus software may additionally scan logs and lock them until the experiment is finished ensuing in jet database errors. You can quickly disable the antivirus or add an exception for log and database folders.
- Disable 0.33-birthday celebration apps from the startup gadgets listing after which restart the server.
- Deploy and use u.S.A.For electricity supply.
- Set up disk controller with battery backup.
- Disable write-returned cache on drive controller.
- Dispose of/reinstall the lively directory at the domain controller.
- Affirm motive force stack.
- If the Jet database error appeared after gentle recuperation, attempt hard recuperation after taking the database backup.
