  The SAP error message "STUN_ORA026 Index & is of Type &; online rebuild is not possible" typically occurs in the context of Oracle databases when attempting to perform an online rebuild of an index that is not eligible for such an operation. This error indicates that the index you are trying to rebuild online is of a type that does not support online rebuilding.
  Cause:
  The primary causes of this error include:
  
  Index Type: The index you are trying to rebuild is of a type that does not support online operations. For example, certain types of bitmap indexes or function-based indexes may not allow online rebuilds.
  Database Version: The version of Oracle you are using may have limitations regarding online index rebuilds.
  Index State: The index may be in a state that does not allow for online rebuilding, such as being unusable or in a specific partition state.
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check Index Type: Verify the type of index you are trying to rebuild. If it is a type that does not support online rebuilds, you will need to perform a standard rebuild instead.
  
  You can check the index type using the following SQL query:
  SELECT index_name, index_type FROM user_indexes WHERE index_name = 'YOUR_INDEX_NAME';
  
  
  
  
  Rebuild Offline: If the index type does not support online rebuilds, you can rebuild the index offline using the following SQL command:
  ALTER INDEX your_index_name REBUILD;
  
  
  Check Index State: Ensure that the index is in a usable state. If it is marked as unusable, you will need to rebuild it before attempting any operations.
  
  
  Review Documentation: Consult the Oracle documentation for your specific version to understand the limitations and capabilities regarding online index rebuilds.
  
  
  Consider Alternatives: If you need to maintain availability while rebuilding, consider creating a new index with the desired properties and then dropping the old index after the new one is validated.
  
  
  Related Information:
  
  Oracle Documentation: Refer to the Oracle Database Administrator's Guide for detailed information on index management and the specific types of indexes supported.
  SAP Notes: Check SAP Notes related to your specific version of SAP and Oracle for any known issues or additional guidance.
  Performance Considerations: Be aware that rebuilding indexes can impact database performance, so plan such operations during maintenance windows or low-usage periods.
