SQL Server Error 9002: How to Fix “Transaction Log is Full” Issue

What is SQL Server Error 9002? 

SQL Server Error Code 9002 generally occurs when the transaction log file of a database becomes full and cannot take in more transactions. Because of this issue, further database operations will remain stopped until the space is freed up or you take any additional action. Below are the main causes behind this error: 

1. The transaction log file has reached its maximum allocated size and cannot grow further.
2. A long-running or uncommitted transaction is consuming excessive log space.
3. Database recovery or backup operations are pending, causing the log to remain occupied.
4. An improper log backup strategy results in the transaction log not being truncated regularly.
5. Insufficient disk space restricts the transaction log file from expanding further.

Manual Fixes to Resolve SQL Server Error 9002

If you are encountering the SQL Server Error Code 9002, here are some proven manual methods that you can perform to resolve the error. You just have to follow the steps carefully to clear some space in the log and get your database back again.

Method 1: Create a Transaction Backup File

One of the major reasons behind this SQL Error Log 9002 is that a full transaction log file cannot be truncated. You can create a transaction backup log to fix SQL Server Error 9002.  When you back up the log file, SQL Server automatically truncates the saved transactions & makes some space for the new ones. This method has worked well for many users. You can also try recreating the transaction log file if needed.

Method 2: Check and Change Log File Growth Settings

If your log file has limited growth restrictions, it may run out of space quickly. To avoid this, increase its size and allow more space for ongoing transactions. You can monitor log space usage with the sys.dm_db_log_space_usage command. If required, enlarge the file using the following T-SQL command:

ALTER DATABASE [database15]  MODIFY FILE  (      NAME = ‘database15’,      SIZE = 200MB  );

Note: SQL Server allows a maximum log file size of up to 2 terabytes (TB).

Method 03: Shrink the Transaction Log File

If unused space within the log file is causing the error, shrinking it can help. This process removes the empty portion of the file and makes room for new transactions. Run the below T-SQL script to shrink the log file:

USE [database15]  GO  DBCC SHRINKFILE (N’database15_Log’ , 0, TRUNCATEONLY)  GO
