• What is the cause and solution for SAP error message SMMSS_ALERTS015 - This alert shows the # of network packet errors noticed by SQL Server ?

  The SAP error message SMMSS_ALERTS015 indicates that there are network packet errors detected by SQL Server. This can be a sign of underlying issues with the network connection between the SAP application server and the SQL Server database. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause
  
  Network Issues: Packet errors can occur due to network instability, such as high latency, packet loss, or network congestion.
  Configuration Problems: Incorrect network configurations, such as mismatched MTU sizes or improper TCP/IP settings, can lead to packet errors.
  Hardware Problems: Faulty network hardware (e.g., routers, switches, network interface cards) can cause packet loss or corruption.
  Firewall or Security Software: Firewalls or security software may interfere with the transmission of packets, leading to errors.
  SQL Server Configuration: Misconfigurations in SQL Server settings related to network protocols can also contribute to packet errors.
  
  Solutions
  
  
  Network Diagnostics:
  
  Use tools like ping, tracert, or pathping to check for latency and packet loss between the SAP application server and SQL Server.
  Monitor network performance using network monitoring tools to identify any bottlenecks or issues.
  
  
  
  Check Hardware:
  
  Inspect network hardware for faults or errors. Replace any faulty components.
  Ensure that network cables are in good condition and properly connected.
  
  
  
  Review Configuration:
  
  Verify the TCP/IP settings on both the SAP application server and SQL Server. Ensure that MTU sizes are consistent across the network.
  Check SQL Server network configuration settings in SQL Server Configuration Manager. Ensure that the correct protocols are enabled.
  
  
  
  Firewall and Security Settings:
  
  Review firewall settings to ensure that they are not blocking or interfering with SQL Server traffic.
  Temporarily disable security software to see if it resolves the issue, and if so, adjust the settings accordingly.
  
  
  
  SQL Server Logs:
  
  Check SQL Server error logs for any additional information or related errors that might provide more context about the packet errors.
  
  
  
  Update Drivers and Firmware:
  
  Ensure that network drivers and firmware for network devices are up to date.
  
  
  
  Consult Documentation:
  
  Refer to SAP and SQL Server documentation for any specific recommendations or known issues related to network packet errors.
  
  
  
  Related Information
  
  Monitoring Tools: Consider using monitoring tools like SAP Solution Manager or SQL Server Management Studio (SSMS) to keep track of performance metrics and alerts.
  Performance Tuning: Regularly review and tune the performance of both the SAP application and SQL Server to minimize the risk of network-related issues.
  SAP Notes: Check SAP Notes for any specific patches or updates related to network performance or known issues with the version of SAP you are using.
  
  By addressing the potential causes and implementing the suggested solutions, you should be able to mitigate the network packet errors indicated by the SMMSS_ALERTS015 message.
