• What is the cause and solution for SAP error message LVCALM032 - Low hit rate in SQL data cache (&1 < &2%) ?

  The SAP error message LVCALM032 indicates that the SQL data cache has a low hit rate, meaning that a significant number of SQL queries are not being served from the cache, leading to performance issues. The message typically specifies the current hit rate and the threshold that has been set (e.g., &1 < &2%).

  Inefficient SQL queries that do not benefit from caching.
  Changes in the database schema or data that invalidate cached SQL statements.
  
  
  
  
  Configuration Issues: The configuration settings for the SQL cache may not be optimal for the workload.
  
  
  Database Load: High load on the database can lead to increased demand for SQL execution, which may exceed the cache's ability to serve requests.
