  The SAP error message DB6PM790 DBCFG - LOGFILSIZ indicates that the size of the log file for the database is below the recommended minimum size. Specifically, the message suggests that the log file size should be at least 16380 (the unit is typically in kilobytes, but it can depend on the specific database system in use).
  Cause:
  This error typically arises when the database log file size is configured to be smaller than what SAP recommends for optimal performance and stability. The log file is crucial for database operations, including transaction logging, recovery, and ensuring data integrity. If the log file is too small, it can lead to issues such as:
  
  Inability to log transactions properly.
  Increased risk of data loss in case of a failure.

  Solution:
  To resolve this error, you need to increase the size of the log file to meet or exceed the recommended size of 16380. The steps to do this can vary depending on the database system you are using (e.g., Oracle, SQL Server, HANA, etc.). Below are general steps that can be adapted based on your specific database:
  
  
  Identify the Database System: Determine which database system your SAP system is using.
  
  
  Access Database Configuration: Use the appropriate database management tools or SQL commands to access the configuration settings for the log files.
  
  
  Modify Log File Size:
  
  For Oracle: You can use the ALTER DATABASE command to resize the log files.
  For SQL Server: You can use the ALTER DATABASE command to modify the size of the transaction log file.
  For HANA: You may need to adjust the configuration parameters in the HANA studio or use SQL commands to change the log file size.
  
  
  
  Restart the Database: After making changes, you may need to restart the database for the changes to take effect.
  
  
  Monitor the Logs: After resizing, monitor the database logs to ensure that the new size is sufficient and that the error does not reoccur.
  
  
  Related Information:
