What Should I Do If a Database Client Problem Causes a Connection Failure?

Updated at: Mar 29, 2019 17:00

Identify a DDS DB instance connection failure caused by a client problem from the following aspects.

  1. ECS Security Policy

    In Windows, check whether the DDS port is enabled in the Windows security policy.

    In Linux, run the iptables command to check whether the DDS port is enabled in firewall settings.

  2. Application Configuration

    Check whether the IP address, port parameter, and Java database connectivity (JDBC) are configured correctly.

NOTE:

If the problem persists, contact post-sales technical support.
