Know how to Solve Exchange Sever Error’ -338 (JET_errBadParentPageLink, Database corrupted)

Microsoft Exchange Server is a transaction-based and fault-tolerant system and thus, has much better protection against data loss as compare to other messaging applications. Despite of the fact, Exchange Server databases still get corrupt. The common reasons of corruption are abnormal system or power failure, database oversize issues (16 GB), antivirus scanning, virus attack, and application bugs. Such instances can affect any of the Information Store databases, which are Priv.edb and Pub.edb. As an administrator, your primary concern is to restore the data, which is applicable using the last backup or by repairing the database. There are several Exchange Server Repair software available that may work against if the Exchange repair utilities fail and/or backup is not available.

As one of the instances, suppose you experience an unexpected power outage with your Exchange Server computer. After this, when you start the database, you get some events (such as event 467, 9297 etc.) logging in the Application log. When you run eseutil commands to check the database integrity, it gives an error as below:
Operation terminated with error -338 (JET_errBadParentPageLink, Database corrupted)…”
If you execute isinteg command, this may result no errors.
Cause
The error -338 occurs due to corruption in parent database and is returned by directory manager. It can occur because of unexpected power failure.
Solution
You can solve the above issue by applying these measures:
  1. Check the last online backup. If available and valid, restore from it.
  2. You can create a new mailbox store and move all possible mailboxes to it
  3. If the above solutions don’t work, you can use esesuitl /r (soft recovery) and/or eseutil /p (hard recovery) commands to repair the corrupted database. The latter option can cause data loss as it deletes the corrupted pages. So, it is suggested to backup your database before applying it.
In case, none of these resolutions proves valid, you need a third-party EDB Repair utility. These software offer safe EDB Repair in each case of database corruption and have high competency to maintain the original database integrity. Moreover, these utilities are quite easy to install and use with self-explaining documentation.

How to recover corrupted EDB files in MS Exchange Server

The Exchange Information Store is a very important component of MS Exchange Server as it contains both mailbox store and public folder store data. All the data of the information store is contained in the EDB files. This means that it is all the more important to know its components, so that in the event of data loss, you know what to do and which kind of exchange recovery to implement. There are certain in-built methods that you can use to perform EDB repair. If these methods are not able to repair EDB file, then you should use a third-party EDB repair software to do so.

The following symptoms indicate that the information store may be corrupted.
  •     Unable to start the Microsoft Exchange Information Store service.
  •     Unable to stop the Information Store service and other dependant services
  •     The Information Store service does not respond while the CPU usage level shows 100 percent
  •     E-mails cannot be retrieved or sent by the client.
    Error messages like “unable to mount the Mailbox store….” (When an attempt is made to mount the mailbox), or “Internal processing error….” (When an attempt is made to mount the database) are displayed.

To resolve this situation, there are following methods that you can use:

    Restore from backup: You should try to restore the database with its online backup. However, you must ensure that the backup is clean and updated before this corruption occurred.

    Run ESEUTIL utility: If you the backup is not clean or not updated, then you should use the ESEUTIL tool. It is able to verify the structure of database tables and perform offline defragmentation on the EDB database.

    Run ISINTEG utility: After performing the ESEUTIL utility, you should use the ISINTEG tool. It rebuilds the EDB information store after the restoration and fixes the errors, it finds, in the information store.

When the backup is not updated or any of the it aforementioned methods fails to restore the desired information, you will need to use a third-party EDB repair software to repair EDB file. Such read-only tools are able to repair EDB files using fast yet sophisticated scanning algorithms.

How to solve Error 939586631 in MS Exchange Server ?

Exchange Storage Group any corruption to the EDB file leads to data inaccessibility and creates unavoidable situations of using a backup. If it is not possible to restore from backup, you need to repair the corrupted database using Exchange inbuilt eseutil repair utility or a third-party Exchange Repair tool.

Cause Of the Error:

The Error - 939586631 particularly results when you run Eseutil /CC command using the incorrect file path pointing to Restore.env file.

Note: Eseutil /CC is the restore mode command, which is applied to run hard recovery on a database that has been restored from an online backup. Exchange Server creates Restore.env file while restoring from backup to control the hard recovery process.

Steps to solve the Exchange Error:

   1. Run Eseutil /CC command using the correct file path of Restore.env file.
   2. Check the database consistency. If it is inconsistent, you can use Eseutil /P and then Eseutil /D command for recovering the database.

For this reason, whenever you find your Exchange database in corrupt state, it is recommended to use a safe third party's EDB Repair Tool.

This Exchange EDB Repair application allows you to extract the contained user mailboxes and restore them at a safe location from a corrupted Exchange database.

Troubleshooting the situation when the EDB file gets beyond 16 GB size in MS Exchange Server SP1

If you are using MS Exchange Server 2003 Service Pack 1 in your organization, then you should be mindful about its size and keep archiving the data. Because if you fail to do so, then the EDB (Exchange Database) file may soon cross its 16 GB limit, thereby making it unmountable and, also, corrupt. The Messaging Database (MDB) automatically stops functioning, and becomes unable to mount, when the mailbox reaches this 16 GB limit. But you need not worry as there are several methods that you can perform for Exchange recovery. But when these do not work, then you should surely use a third-party Exchange recovery software.

Consider a scenario in which you are unable to mount MS Exchange Server SP 1. When you check the event log, the following event IDs are logged in it:

“Event Type: Error
Event Source: MSExchangeIS
Event Category: General
Event ID: 1112
Description: The database "Mailbox Store (Server Name)" has reached the maximum allowed size. Attempting to unmount the database.
Event Type: Warning
Event Source: ESE
Event Category: Space Management
Event ID: 445
Description: Information Store (3160) The database D:\Program Files\Exchsrvr\MDBDATA\priv1.edb has reached its maximum size of 16383 MB. If the database cannot be restarted, an offline defragmentation may be performed to reduce its size.”

Cause:

The most probable cause of this issue is that the size of the mailbox has increased 16 GB.

Resolution:

To resolve this issue, there are following methods that you can use to perform Exchange Server recovery and get the Exchange Server back on track:

You should try to upgrade to MS Exchange Server 2003 Service Pack 2 by downloading and installing the Service Pack 2. Restart the system after installing it.

If you are the system administrator in your organization, then you can employ the following steps:

 i.Increase the size limit of the database by 1 GB although temporarily.
 ii.Remove the content that you do not need or take a backup of such items.
 iii.Then, defragment the database to compact it to such an extent that it is under the specified limits of the database size.

You can use the Recovery Storage Group feature to mount the database in the recovery storage group. After that, use the Exmerge.exe tool to retrieve the inaccessible user mailboxes from the database.

If you are still unable to mount the system, then you ought to take desperate measures to recover the Exchange Server. For such cases, a third-party Microsoft Exchange recovery software proves to be the most handy resolution. Such Exchange recovery tools are so efficient and reliable that the databases remain untouched during the Exchange Server recovery.

The most trusted and recommended tool in this respect is Stellar Phoenix Exchange Server Recovery that extracts user mailboxes in the form of separate PST files from damaged EDB files. Compatible with Windows 7, Vista, Server 2003, XP, and 2000, this Exchange recovery software works on EDB files created for MS Exchange Server 5.5, 2000, 2003, and 2007.
