Use the advice given here to help you to resolve common problems that can arise when you start an integration node.
When you start an integration node by using the mqsistart command, the mqsicvp command is run automatically to check that the environment is set up correctly (for example, the installed level of Java™ is supported). On Linux and UNIX, the mqsicvp command also verifies that the ODBC environment (if specified) is configured correctly. For more information, see mqsicvp command.
