Fix Exchange Dirty Shutdown Error in Easiest Way

In order to start exchange server smoothly, it is quite important that the database is shut down in a proper way. For this, it has to make sure that the database is “detached” to the transaction log files data in transaction log is committed to the database files. However, at the time of starting the exchange server then this condition is checked out and the missing data in the database files and after that it is committed with the help of available log files automatically. If the desired database is detached from the transaction log files the exchange server does not need the previous log files to start up. Such log files prove to be a great asset whenever an older version of database has to be restored. However, it is always recommended not to delete any log files permanently until it is make sure that older version of database is not required to be replayed.

However, in order to check if a database is properly detached or not, you have to verify that if it is in clean shutdown state or dirty shutdown state. In order to examine the state value of Exchange Server database you can follow the below mentioned steps:

First of all click on “Start” button and in the run textbox, you have to enter ‘cmd’ and hit enter.

For Public Folders, type the command:

For Private Folders, type the command:

However, it is assumed that Exchange Server is installed at: ‘c:\program files\exchsrvr folder’ and the database is saved at ‘c:\program files\exchsrvr\mdbdata folder’.

If the State = Clean Shutdown then it means that the database is correctly detached.

clean-shutdown

Database State: Clean Shutdown

If the State=Dirty Shutdown then it means there are some transactions that are awaited to committed to the database.

dirty-shutdown

Database State: Dirty Shutdown

What is Dirty System Shutdown?

As we all know that Exchange Server database is based on JET engine where all log files are responsible to keep a track of all input and output operations in the database file. ESE uses the concept of mailbox database cache so that it can reduce the input-output operation count.

It has been seen that whenever an operation is loaded to the cached memory and it is not committed to the information store then the JET engine marks It as DIRTY. Until the pending transaction is committed to the database then it is always considered as updated and till dirty pages are there in the database then t is considered as inconsistent.

However, until the transaction could have completed, if the system shuts down accidentally then the database remain attached to the log file because of which dirty system shutdown error is received on the screen.

There are two kinds of shutdown error. They are as follows:

Error 550:

error-550

Error 528:

error-528

How to fix error when log files are missing or in dirty shutdown state

In the case of dirty shutdown state, hard recovery of database will work out. This type of recovery generally differs from the above mentioned state because this used to replay transaction log by just simply restoring transaction log by restoring database from online backup.  If the recently used database and the valid database backup is available then it can restore .edb, .log and .stm files from them. After this process is done, restore.env file will be automatically created in temporary folders.

restore.env

Note: Make sure that a copy of restore.env and log files are created because hard recovery process involves loss of some data.
