In this article I am going to discuss techniques to increase Exchange database size, why we need to increase size and also giving you a simplest way to resolve database errors…
Whenever the file size is greater than the database size then there will be an error occurred and the write operation to the database will not be completed. And this error creates big trouble that should be resolved immediately because the database is responsible for storing all the data files of an organization. Some database error is given bellow.
If the above database error message comes when EDB file size become grater then the free space in database this situation led to dismount the database, to manage this situation we have a best way i.e. increase the database size.
Now let us discuss database size limit in various versions of Microsoft Exchange Server.
Exchange Server 2003 Database Size Limit
Exchange Server launched in two editions i.e. standard edition and enterprise edition. Standard edition supports two database in single storage group (one is for mailbox and other is for public folder). It is launched in two editions sp1 and sp2, in SP1 the database size is 16 GB and in SP2 database size is 18GB with the maximum size 75 GB. But in Enterprise edition the database size is 8000 GB and it depends on hardware also.
Exchange Server 2007, 2010 and 2013 Database Size Limit
Exchange database 2007 standard edition five database with up to five storage group which just expandable just two storage group in 2003 and lower versions. The default database size limit is 50 GB per database also that can be increased to 15 TB and no default database size limit for Enterprise edition of Exchange Server 2007.
In Exchange Server 2013 the maximum EDB size limit is 16 TB. But it is recommended that use 2 TB for a database other vise it will take more time in backup and recovery process.
Now let's talk about the solution of this particular problem, if you are thinking that you have an option of offline Defragmentation you are wrong here because this method requires at least 1.5 times database free space to run this utility.
Here I am giving you proper step by step guidance to increase database size and remove the errors as stated above and discussed all the possibility that can cause the JET_ErrorDiskIO 1022 now let us discuss an easy way to deal with this error.
Note: - keep one thing in mind that incorrectly editing the registry can cause system failure so be careful while performing the operation.
Step 1: - Reach to system Registry press window+r and type REGEDIT, run opened window and brows the following key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\<Server Name>\Private∼<database GUID>>
Note: - If the "Database Size Limit in GB" DWORD does not exist for the sub key then create a new DWORD "Database Size Limit in GB", and then set its decimal value to the desired size in gigabytes.
>Step 2: - Restart Exchange information store service.
Step 3: - Check event viewer for confirming the change is size limit.
Conclusion I have discussed Exchange database size limits, method to increase the database size and related errors as well I hope this article will help to resolve the database error.
