When trying to register a node ( when installing or registering somewhere else), the command unims -register throws the error 300.
It is impossible to know wether the issue is related to a wrong login / password or a timeout on the reply from the uvms to the request.

Error Message :
In case there is an error in the registration of a DUAS on a UVMS, the error message does not provide useful information to the user:
$UNI_DIR_EXEC/unims -register -mshost -msport 4184 -login <incorrect username> -pwd password--> Incorrect login
$UNI_DIR_EXEC/unims -register -mshost -msport 4184 -login <correct username>-pwd wrong_password--> Incorrect password

The same error on the command unims -register appears after a timeout of 15 seconds in case there is a network issue between the UVMS and the node.
Unable to connect to UVMS: error 300 (-1)

Solution details:

The command unims -register will now throw an error 205 for timeout errors when waiting for the reply of the UVMS.

The new output of the command in case of a timeout is:

Unable to connect to UVMS: error 205 (check U_UVMS_TIMEOUT parameter) (-1)

Therefore, you will need to increase the value of the variable U_UVMS_TIMEOUT (15 seconds by default).

For that, you can launch the following command to increase it to 120 seconds:


Additional Information

In case the node is already registered, make sure to delete it from the node list before trying to register it.
