• What is the cause and solution for SAP error message DB02017 - Segments with non-zero PCTINCREASE ?

  The SAP error message DB02017 indicates that there are segments in the database that have a non-zero PCTINCREASE setting. This setting is related to how the database manages space allocation for segments. When a segment has a non-zero PCTINCREASE, it means that the database will increase the size of the segment by a percentage when it needs more space, which can lead to fragmentation and performance issues.
  Cause:
  
  Non-Zero PCTINCREASE: The primary cause of this error is that one or more database segments have a PCTINCREASE value set to a non-zero percentage. This can happen during the initial configuration of the database or if the settings were changed later.
  Database Configuration: The database may have been configured to allow for dynamic growth of segments, which can lead to this setting being applied.
  
  Solution:
  
  
  Change PCTINCREASE to Zero: The recommended solution is to change the PCTINCREASE setting for the affected segments to zero. This means that the database will allocate a fixed amount of space rather than a percentage, which can help reduce fragmentation.
  
  You can do this by executing a command in the database management system (DBMS) to alter the segment settings. The exact command will depend on the specific database you are using (e.g., Oracle, SQL Server, etc.).
  
  
  
  Reorganize Segments: After changing the PCTINCREASE setting, it may be beneficial to reorganize the segments to optimize space usage and performance.
  
  
  Monitor Database Performance: After making changes, monitor the database performance to ensure that the changes have had the desired effect and that there are no further issues.
  
  
  Related Information:
  
  Database Documentation: Refer to the documentation for your specific database system for detailed instructions on how to change segment settings.
  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, it may be advisable to consult with a database administrator (DBA) to ensure that changes are made correctly and do not impact other operations.
  
  Conclusion:
  The DB02017 error message indicates a configuration issue with segment space allocation in the database. By setting the PCTINCREASE to zero and reorganizing the segments, you can resolve the issue and improve database performance. Always ensure to back up your database before making significant changes.
