• What is the cause and solution for SAP error message 14077 - Shared lock statistics activated ?

  The SAP error message 14077, which states "Shared lock statistics activated," typically occurs in the context of database operations where shared locks are being utilized. This message is often related to the locking mechanism in SAP systems, particularly when dealing with database transactions that require concurrent access to data.
  Cause:
  The error message indicates that shared lock statistics have been activated, which means that the system is tracking the usage of shared locks. This can happen due to various reasons, including:
  
  Database Configuration: The database may be configured to track shared lock statistics, which can lead to performance overhead if not managed properly.
  High Concurrency: If there are many concurrent transactions trying to access the same data, the system may activate shared lock statistics to manage these locks effectively.
  Long-Running Transactions: Transactions that take a long time to complete can hold locks for extended periods, leading to the activation of shared lock statistics.
  
  Solution:
  To resolve the issue related to the error message 14077, consider the following steps:
  
  
  Review Lock Statistics Settings: Check the database and SAP system settings related to lock statistics. You may want to adjust the configuration to reduce the overhead of tracking shared locks if it is not necessary for your operations.
  
  
  Optimize Transactions: Analyze the transactions that are causing the locks. If possible, optimize these transactions to reduce their execution time and the duration for which they hold locks.
  
  
  Monitor Lock Usage: Use transaction codes like SM12 (to view locks) and SM21 (to check system logs) to monitor lock usage and identify any long-running transactions or deadlocks.
  
  
  Database Performance Tuning: Consider tuning the database performance settings to handle concurrent access more efficiently. This may involve adjusting isolation levels or lock timeout settings.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may provide specific guidance or patches related to this error message.
  
  
  Engage SAP Support: If the issue persists and significantly impacts system performance, consider reaching out to SAP Support for further assistance.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SM12 (to manage locks), SM21 (to view system logs), and ST22 (to check dumps).
  Database Documentation: Review the documentation for your specific database (e.g., HANA, Oracle, SQL Server) regarding lock management and performance tuning.
  Performance Monitoring Tools: Utilize SAP's performance monitoring tools to analyze system performance and identify bottlenecks related to locking.
  
  By following these steps, you should be able to address the underlying causes of the error message and improve the overall performance of your SAP system.
