• What is the cause and solution for SAP error message 00249 - Active connection table is full; try again later ?

  The SAP error message "00249 Active connection table is full; try again later" indicates that the system has reached the maximum number of active connections allowed for the database or application server. This can happen due to various reasons, such as high user load, insufficient resources, or misconfiguration.
  Causes:
  
  High User Load: A sudden increase in the number of users or processes trying to connect to the SAP system can exhaust the available connections.
  Configuration Limits: The maximum number of connections allowed may be set too low in the system configuration.
  Resource Exhaustion: The underlying database or application server may be running out of resources (e.g., memory, CPU).
  Connection Leaks: Applications or processes that do not properly close connections can lead to exhaustion of available connections over time.
  Network Issues: Problems in the network can cause connections to hang, leading to a situation where the connection table appears full.
  
  Solutions:
  
  
  Increase Connection Limits:
  
  Review and increase the maximum number of connections allowed in the SAP system configuration. This can typically be done in the instance profile parameters (e.g., rdisp/max_active_wp for work processes).
  For database connections, check the database configuration settings and increase the maximum connections if necessary.
  
  
  
  Monitor and Optimize Usage:
  
  Use transaction codes like SM50 (for work processes) and SM66 (for global work processes) to monitor active processes and identify any bottlenecks.
  Analyze the workload and optimize the usage of connections by identifying and terminating unnecessary or long-running sessions.
  
  
  
  Check for Connection Leaks:
  
  Review custom programs or third-party applications to ensure they are properly managing database connections and closing them when no longer needed.
  
  
  
  System Resources:
  
  Ensure that the application server and database server have sufficient resources (CPU, memory, etc.) to handle the expected load.
  Consider scaling up the hardware or optimizing the existing resources.
  
  
  
  Restart Services:
  
  If the issue persists, consider restarting the SAP application server or database to clear any stuck connections.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
