• What is the cause and solution for SAP error message SDBALM174 - High proportion of SQL data in the data cache (&1&3 > &2&3) ?

  The SAP error message SDBALM174 indicates that there is a high proportion of SQL data in the data cache, which can lead to performance issues in the system. This message typically arises when the amount of SQL data in the data cache exceeds a certain threshold, which can negatively impact the overall performance of the database and the application.
  Cause:
  
  
  High SQL Data Volume: The primary cause of this error is that a significant amount of SQL data is being cached, which can occur due to:
  
  Large or complex SQL queries that return a lot of data.
  Inefficient database design or poorly optimized queries.
  High transaction volume leading to increased data caching.
  
  
  
  Insufficient Cache Size: The data cache may not be adequately sized to handle the volume of SQL data being processed, leading to a high proportion of SQL data in the cache.
  
  
  Configuration Issues: Incorrect configuration settings for the database or the application server can also contribute to this issue.
  
  
  Solution:
  
  
  Analyze SQL Queries: Review the SQL queries that are being executed to identify any that can be optimized. Look for:
  
  Unnecessary data retrieval (e.g., SELECT * instead of specific columns).
  Missing indexes that could speed up query execution.
  
  
  
  Adjust Cache Size: Increase the size of the data cache if possible. This can be done through the database configuration settings. Consult your database documentation for specific instructions on how to adjust cache settings.
  
  
  Monitor and Tune Performance: Use performance monitoring tools to analyze the database and application performance. Look for bottlenecks and areas where performance can be improved.
  
  
  Database Maintenance: Regularly perform database maintenance tasks such as:
  
  Updating statistics.
  Rebuilding indexes.
  Cleaning up old or unnecessary data.
  
  
  
  Configuration Review: Review the configuration settings of both the database and the application server to ensure they are optimized for your workload.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes or updates that may address this specific error message or provide additional guidance.
