• What is the cause and solution for SAP error message DB6PM165 - Number of block pages has been reduced to 98% of buffer pool size ?

  The SAP error message DB6PM165 indicates that the number of block pages in the database has been reduced to 98% of the buffer pool size. This message is typically related to the database's memory management and buffer pool configuration. Here’s a breakdown of the cause, potential solutions, and related information:
  
  Cause:
  
  Buffer Pool Configuration: The buffer pool is a memory area that caches database pages to improve performance. If the number of block pages exceeds a certain threshold (in this case, 98% of the buffer pool size), the database system may reduce the number of pages to maintain performance and stability.
  High Load or Inefficient Queries: If there are many concurrent queries or inefficient queries running, they may consume more buffer pool memory, leading to this warning.
  Database Growth: As the database grows, the existing buffer pool size may become insufficient to handle the increased data load, leading to this message.
  
  
  Solution:
  
  Increase Buffer Pool Size:
