How To Fix DB6105 - DB configuration parameter BUFFPAGE is active

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 105

• Message text: DB configuration parameter BUFFPAGE is active

What causes this issue?

There is not an explicit size specified for the buffer pool.

System Response

This is only a problem if you intended to explicitly specify a size for
the buffer pool, and the performance is insufficient due to inadequate
buffer quality that is caused by the buffer pool being too small.

How to fix this error?

You can set a new value for the size of the buffer pool with the
command ALTER BUFFERPOOL. The new value becomes effective as soon as
you have restarted the database. Note that the increased demand for
virtual memory causes more paging, if there is not enough real main
memory available.

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 DB6105 - DB configuration parameter BUFFPAGE is active ?

  The SAP error message DB6105 indicates that the database configuration parameter BUFFPAGE is active. This parameter is related to the database's buffer management and can affect performance and memory usage.
  Cause:
  The BUFFPAGE parameter is typically used to control the number of pages that can be buffered in the database. When this parameter is active, it may indicate that the database is configured to use a certain amount of memory for buffering data pages. If the system is experiencing issues related to memory allocation, performance, or if the parameter is not set optimally for the workload, it can lead to this error message.
  Solution:
  To resolve the DB6105 error, consider the following steps:
  
  
  Check Database Configuration: Review the current settings of the BUFFPAGE parameter. Ensure that it is set to a value that is appropriate for your system's workload and available memory.
  
  
  Adjust Buffer Size: If necessary, adjust the BUFFPAGE parameter to a more suitable value. This may involve increasing or decreasing the buffer size based on the performance requirements and available resources.
  
  
  Monitor System Performance: Use monitoring tools to observe the database performance and memory usage. This can help identify if the current buffer settings are causing bottlenecks or if adjustments are needed.
  
  
  Consult Documentation: Refer to the database documentation for specific guidance on the BUFFPAGE parameter and its implications. Different database systems may have different recommendations.
  
  
  Database Restart: In some cases, changes to database configuration parameters may require a restart of the database to take effect.
  
  
  Seek Expert Help: If you are unsure about making changes to the database configuration, consider consulting with a database administrator or SAP support for assistance.
  
  
  Related Information:
  
  Database Documentation: Check the official documentation for your specific database (e.g., SAP HANA, Oracle, SQL Server) for detailed information on the BUFFPAGE parameter and its impact.
  SAP Notes: Look for relevant SAP Notes that may address this specific error message or provide additional troubleshooting steps.
  Performance Tuning: Consider engaging in performance tuning practices for your database to optimize memory usage and overall performance.
  
  By following these steps, you should be able to address the DB6105 error and optimize your database configuration.
