• What is the cause and solution for SAP error message S1191 - Table access statistics are turned off ( rsdb/staton = 0 ) ! ?

  The SAP error message S1191 indicates that table access statistics are turned off in your SAP system. This can affect performance monitoring and optimization, as the system is unable to collect statistics on how tables are accessed.
  Cause:
  The cause of this error is that the parameter rsdb/staton is set to 0, which disables the collection of table access statistics. This parameter controls whether the SAP system gathers statistics about database table accesses, which can be useful for performance tuning and analysis.
  Solution:
  To resolve this issue, you need to enable table access statistics by changing the value of the rsdb/staton parameter. Here’s how you can do that:
  
  
  Access the SAP GUI: Log in to your SAP system.
  
  
  Transaction Code RZ10: Enter the transaction code RZ10 in the command field. This transaction is used to maintain profile parameters.
  
  
  Select the Profile: Choose the appropriate instance profile (usually the one that is active for your application server).
  
  
  Edit Parameters: Click on the "Extended Maintenance" button to edit the parameters. 
  
  
  Add or Modify Parameter: Look for the parameter rsdb/staton. If it is not present, you can add it. Set its value to 1 to enable table access statistics.
  rsdb/staton = 1
  
  
  Save Changes: After making the changes, save the profile.
  
  
  Restart the Instance: For the changes to take effect, you will need to restart the SAP instance.
  
  
  Related Information:
  
  Performance Monitoring: Enabling table access statistics can help in identifying performance bottlenecks related to database access patterns.
  Transaction ST03N: After enabling the statistics, you can use transaction ST03N to analyze workload and performance data.
  Database-Specific Settings: Depending on the database you are using (e.g., Oracle, HANA, etc.), there may be additional settings or considerations for optimizing performance.
  Documentation: Refer to the SAP Help Portal or the specific documentation for your SAP version for more detailed information on performance tuning and monitoring.
  
  By enabling table access statistics, you can gain insights into how your database tables are being accessed, which can help in optimizing queries and improving overall system performance.
