• What is the cause and solution for SAP error message DB6PM770 - DBCFG - USEREXIT=NO and LOGRETAIN=NO will prevent roll-forward recovery ?

  The SAP error message DB6PM770 DBCFG - USEREXIT=NO and LOGRETAIN=NO will prevent roll-forward recovery indicates a configuration issue related to the database settings that affect the ability to perform roll-forward recovery. This error typically arises in the context of database management and recovery strategies in SAP systems, particularly when using databases like IBM Db2 or Oracle.
  Cause:
  
  
  USEREXIT=NO: This setting indicates that the database is not configured to use user exits for logging. User exits are typically used to enhance the logging capabilities of the database, which can be crucial for recovery processes.
  
  
  LOGRETAIN=NO: This setting means that the database is not retaining logs for recovery purposes. When log retention is disabled, the database cannot keep track of changes made to the data, which is essential for roll-forward recovery.
  
  
  Solution:
  To resolve this error and enable roll-forward recovery, you need to adjust the database configuration settings:
  
  
  Enable User Exit:
  
  Change the USEREXIT setting to YES. This may involve modifying the database configuration files or using database management commands, depending on the specific database system you are using.
  
  
  
  Enable Log Retention:
  
  Change the LOGRETAIN setting to YES. This will ensure that the database retains the necessary logs for recovery operations.
  
  
  
  Database Configuration:
  
  Depending on the database you are using (e.g., Db2, Oracle), you may need to refer to the specific documentation for that database to find the exact commands or configuration files to modify.
  
  
  
  Backup and Recovery Strategy:
  
  Review your backup and recovery strategy to ensure that it aligns with your business requirements. Consider implementing regular backups and ensuring that logs are retained for an appropriate duration.
  
  
  
  Testing:
  
  After making the changes, test the recovery process to ensure that roll-forward recovery works as expected.
  
  
  
  Related Information:
  
  Database Documentation: Always refer to the official documentation for your specific database system for detailed instructions on configuring user exits and log retention.
  SAP Notes: Check SAP Notes for any specific recommendations or patches related to this error message.
  Database Administration: If you are not familiar with database administration, consider consulting with a database administrator (DBA) who can assist with these configurations.
  Monitoring: Implement monitoring tools to keep track of database configurations and ensure that they remain compliant with your recovery requirements.
  
  By addressing the USEREXIT and LOGRETAIN settings, you can enable roll-forward recovery and mitigate the risk of data loss in your SAP environment.
