• What is the cause and solution for SAP error message SDB2U022 - MEMBER CLUSTER = 'YES' only with SEGSIZE = 0 ?

  The SAP error message SDB2U022 indicates a configuration issue related to the database storage parameters for a table or index in SAP's database environment. Specifically, this error arises when a member cluster is set to 'YES' while the segment size (SEGSIZE) is set to 0. 
  Cause:
  In SAP databases, particularly when using DB2, the MEMBER CLUSTER option is used to determine how data is stored in relation to the clustering of records. When MEMBER CLUSTER is set to 'YES', it indicates that the records should be stored in a clustered manner based on the member. However, if the SEGSIZE is set to 0, it means that there is no segment size defined for the storage of the data, which is contradictory to the requirement of having a member cluster.
  Solution:
  To resolve this error, you need to adjust the database table or index definition to ensure that the SEGSIZE is set to a valid value that is greater than 0. Here are the steps you can take:
  
  
  Modify the Table Definition:
  
  Access the database definition for the table or index that is causing the error.
  Change the SEGSIZE parameter from 0 to a valid positive integer. The value you choose should be based on your database design and performance considerations.
  
  
  
  Recreate the Table/Index:
  
  If the table or index is already created and you cannot modify it directly, you may need to drop and recreate it with the correct parameters.
  
  
  
  Check Documentation:
  
  Refer to the SAP and DB2 documentation for guidelines on setting the SEGSIZE and MEMBER CLUSTER options. This will help you understand the implications of your changes.
  
  
  
  Test Changes:
  
  After making the changes, test the application to ensure that the error is resolved and that the database performs as expected.
  
  
  
  Related Information:
  
  DB2 Documentation: Review the official IBM DB2 documentation for detailed explanations of storage parameters, including SEGSIZE and MEMBER CLUSTER.
  SAP Notes: Check SAP Notes for any specific recommendations or patches related to this error message.
  Performance Considerations: Understand how the choice of SEGSIZE can impact database performance, especially in terms of I/O operations and data retrieval.
  
  By following these steps, you should be able to resolve the SDB2U022 error and ensure that your database configuration is correct.
