Most problems with the VMI connection are due to entering the IP address of the
Vocera Voice Server or cluster incorrectly. You cannot solve this
problem by editing the value of the environment variable alone. To troubleshoot this
issue, you must also delete the IP address list from the database and set up the VMI connection again.
Note:
Before you begin, double-check to make sure that your system has an available VMI license.
An unavailable VMI license also prevents you from establishing the VMI connection.
To troubleshoot an incorrect IP address:
-
Update the value of the VOCERA_SERVER_IP_ADDRESS environment variable to
the correct IP address or cluster list.
-
Disable the MySQL "Safe Updates" preference to allow you to update the database easily:
-
Use the Windows Start menu to launch MySQL Workbench.
