• What is the cause and solution for SAP error message STREX554 - IndexServer Handles ?

  The SAP error message STREX554 typically relates to issues with the Index Server in SAP HANA, particularly concerning the number of handles or resources being utilized. This error can occur when the system is running out of available handles for the Index Server, which can lead to performance degradation or system instability.
  Cause:
  
  Resource Exhaustion: The Index Server may be running out of available handles due to high workload or insufficient resources allocated to the HANA instance.
  Configuration Issues: The configuration settings for the Index Server may not be optimized for the current workload, leading to excessive handle usage.
  Memory Leaks: There could be memory leaks in the application or in the HANA system itself, causing handles to not be released properly.
  High Concurrency: A high number of concurrent connections or queries can lead to an increased demand for handles.
  
  Solution:
  
  Monitor Resource Usage: Use SAP HANA Studio or HANA Cockpit to monitor the resource usage of the Index Server. Check for any spikes in memory or handle usage.
  Increase Handle Limits: If the system is consistently running out of handles, consider increasing the handle limits in the configuration settings. This can be done by adjusting the max_connections or max_user_connections parameters in the HANA configuration.
  Optimize Queries: Review and optimize the SQL queries being executed to reduce the load on the Index Server. This may involve indexing, query rewriting, or reducing the number of concurrent queries.
  Check for Memory Leaks: Investigate the application and HANA system for potential memory leaks. This may involve reviewing application code or checking for known issues in the HANA version being used.
  Scale Resources: If the workload has increased significantly, consider scaling up the HANA instance by adding more memory or CPU resources.
  Restart the Index Server: As a temporary measure, restarting the Index Server can free up handles and resolve the issue, but this should be done with caution and ideally during a maintenance window.
