This error typically arises in the context of SAP Master Data Governance (MDG) when the system is unable to connect to the database for various reasons.
  Causes:

  Solutions:
  
  
  Check Database Connection Configuration:
  
  Go to transaction DBACOCKPIT or SM59 to verify the database connection settings.
  Ensure that the connection parameters (like hostname, port, database name, user, and password) are correct.
  
  
  
  Test the Database Connection:
  
  Use the DBACOCKPIT or SM59 transaction to test the connection. This can help identify if the connection is indeed valid or if there are issues.
