Smart SAP Assistant

• What is the cause and solution for SAP error message CNV_IUUC_REPLICATION381 - The database only accepts encrypted connections ?

  The SAP error message CNV_IUUC_REPLICATION381 indicates that the database you are trying to connect to requires encrypted connections, but the current connection attempt is not using encryption. This is a common issue when the database has been configured to enforce secure connections, such as SSL/TLS, and the client application (in this case, SAP) is not set up to comply with this requirement.
  Cause:
  
  Database Configuration: The database is configured to only accept encrypted connections for security reasons.
  Client Configuration: The SAP system or the specific connection settings do not specify that encryption should be used when connecting to the database.
  Network Security Policies: Organizational policies may require all database connections to be encrypted to protect sensitive data.
  
  Solution:
  To resolve this error, you need to ensure that your SAP system is configured to use encrypted connections when connecting to the database. Here are the steps you can take:
  
  
  Check Database Settings:
  
  Verify the database configuration to ensure it is set to require encrypted connections. This may involve checking the database server settings or configuration files.
  
  
  
  Update SAP Connection Settings:
  
  Modify the connection settings in your SAP system to enable encryption. This typically involves:
  
  Accessing the SAP GUI.
  Navigating to the transaction code DBACOCKPIT or SM59 (for RFC connections).
  Editing the connection parameters to include encryption options (e.g., SSL).
  For example, if you are using an Oracle database, you may need to set the SSL parameter to true.
  
  
  
  
  
  Install Required Certificates:
  
  If your database uses SSL/TLS, ensure that the necessary certificates are installed on the SAP server. This may involve:
  
  Importing the database server's SSL certificate into the SAP trust store.
  Configuring the SAP system to trust the certificate authority (CA) that issued the database's SSL certificate.
  
  
  
  
  
  Test the Connection:
  
  After making the necessary changes, test the connection to ensure that it is now using encryption. You can do this by attempting to connect to the database again and checking for any error messages.
  
  
  
  Consult Documentation:
  
  Refer to the official SAP documentation or the documentation for your specific database for detailed instructions on configuring encrypted connections.
  
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any specific guidance or patches related to this error message. SAP Notes often provide solutions for known issues.
  Database Documentation: Review the documentation for your specific database (e.g., Oracle, SQL Server, HANA) for details on configuring SSL/TLS connections.
  Network Security: Ensure that your organization's network security policies are adhered to when configuring encrypted connections.
  
  By following these steps, you should be able to resolve the CNV_IUUC_REPLICATION381 error and establish a secure connection to your database.
