How To Fix DB6597 - Maximum fill level of the secondary log files

SAP Error Message - Details

• Message type: E = Error

• Message class: DB6 - DB6: Alert Monitoring and Alert Configuration

• Message number: 597

• Message text: Maximum fill level of the secondary log files

What causes this issue?

This value is the maximum fill level (in percent) of the secondary log
area since the system was started or since the last monitor reset.

System Response

The more secondary log area that needs to be added, the worse
performance is. If the secondary log area is full, it means
transactions are terminating due to insufficient log area. As it is
these transactions that have logged a large number of changes,
resetting them can be expensive.

How to fix this error?

If an error occurs, you can extend the log area by increasing the
maximum number of log files:
<LB>UPDATE DB CFG USING LOGPRIMARY <value></> (primary log files)
<LB>UPDATE DB CFG USING LOGSECOND <value>,,</> (secondary log
files)
You can also extend the log area by increasing the size of individual
files:
<LB>UPDATE DB CFG USING LOGFILSIZ <value>,,</> (parameter
LOGFILSIZ)

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message DB6597 - Maximum fill level of the secondary log files ?

  The SAP error message DB6597, which indicates that the maximum fill level of the secondary log files has been reached, typically arises in the context of database management within SAP systems. This error is related to the database's transaction log files, which are crucial for maintaining data integrity and supporting recovery processes.
  Cause:
  
  Log File Size Limit: The secondary log files have a predefined maximum size, and when this limit is reached, the system cannot write any more log entries.
  Long-Running Transactions: If there are long-running transactions that hold locks and prevent log file clearance, this can lead to the log files filling up.
  Insufficient Log File Management: If the log files are not being backed up or cleared regularly, they can accumulate and reach their maximum fill level.
  Database Configuration Issues: Incorrect configuration settings for log file management can also contribute to this issue.
  
  Solution:
  
  Backup the Log Files: If you are using a database that supports log backups (like SQL Server, Oracle, etc.), perform a log backup to free up space in the log files.
  Check for Long-Running Transactions: Identify and resolve any long-running transactions that may be holding up log file clearance. You can use transaction monitoring tools or SQL queries to find these transactions.
  Increase Log File Size: If necessary, consider increasing the size of the secondary log files or adjusting the configuration settings to allow for larger log files.
  Regular Maintenance: Implement regular maintenance tasks, such as log backups and clearing old logs, to prevent the log files from filling up in the future.
  Database Configuration Review: Review the database configuration settings related to log file management to ensure they are optimized for your workload.
  
  Related Information:
  
  Database Documentation: Refer to the specific database documentation (e.g., SAP HANA, Oracle, SQL Server) for detailed instructions on managing log files.
  SAP Notes: Check SAP Notes for any specific recommendations or patches related to this error message.
  Monitoring Tools: Utilize SAP monitoring tools (like SAP Solution Manager) to keep an eye on database performance and log file usage.
  Consult with DBA: If the issue persists, consult with a Database Administrator (DBA) who can provide insights and help with advanced troubleshooting.
