  Solutions
  
  
  Check Database Status:
  
  Ensure that the database service is running. You can check this using the database management tools or commands specific to your database system (e.g., psql for PostgreSQL, sqlplus for Oracle).
  
  
  
  Verify Connection Parameters:
  
  Check the database connection parameters in the SAP profile or configuration files (e.g., saplogon.ini, tnsnames.ora for Oracle). Ensure that the hostname, port, username, and password are correct.
  
  
  
  Test Network Connectivity:
