Are you trying to fix SQL Server Error 9002?
We can help you.
Sometimes in SQL server, when a log file gets filled up with transaction logs, it shows SQL Server Error 9002.
Usually, the transaction logs get filled when the SQL server database is online or if it is in recovery mode.
Therefore, SQL Server Error 9002 indicates that the SQL Transaction Log file is full or the database is running out of space. This makes the transaction log file to increase until the log file utilizes all the available space in disk. When it cannot expand any more, you become unable to perform any modification operations on the database.
In this context, we shall look into method to fix SQL Server Error 9002 when the transaction logs are full in a log file.
We can do the following steps to fix this error:
1. First create a backup and truncate the transaction logs
2. Make the log space available
3. Move log file to another disk drive
4. After that increase the size of the log file
5. Add another log file on a separate disk
6. Finally complete or kill a long-running transaction
If our database is in full or bulk-logged recovery model and if the transaction log is not backed up, we must take the backup of transaction logs and allow Database Engine to truncate the transaction logs to the point of the last backup.
This will free some space for new transactions.
We can do this by deleting or moving some other files on which the transaction log file is contained.
If we are not able to make the disk space available for the drive on which our transaction log file is contained, we can try to move the log file on another disk with available space.
We must keep in mind the following points while doing this:
i. We have to ensure that the other disk has enough space for new transaction logs.
ii. We can detach the database by using the following command:
iii. This action will make the log file unavailable as long as we do not re-attach it.
iv. For reattaching the database, we can execute the following:
If we have enough space on the log disk, then we can increase its size.
To increase the size of the log file, we can either do any of the following:
i. Produce a single growth increment
ii. Enable autogrow by the ALTER DATABASE statement
We can also add an additional log file for the database and gain more space.
i. To add another log file on a separate disk, use ALTER DATABASE ADD LOG FILE.
ii. Use MODIFY FILE clause of the ALTER DATABASE to enlarge the log file.
i. Discovering long-running transactions
A very long-running transaction can cause the transaction log to fill.
For checking long-running transactions, we can use one of the following:
2. DBCC OPENTRAN
ii. Kill a transaction
It will be better to end the process if it's taking too long.
We can use the KILL statement for doing this.
