Hi Jakob,


The port could be in use by an external (non-ML) process. You could also do
xdmp:http-get on the port number. Make sure to use a small timeout though..
;-)



Cheers,

Geert

Hello,



if I wanted to script the creation of an xdbc appserver and I don't really
care about the port number to use (so let's say I use xdmp:random(65535) +
8003), how can I find out whether that port is already in use by an already
existing server?



Basically I'm looking for a definition of the local:port-number-in-use($pn)
below.

*declare function **local:get-port-number*()
*as xs:integer*
{
    *let $pn* := *xdmp:random*(65535 + 8003)
    *return *
        *if* (*local:port-number-in-use*(*$pn*))
            *then **local:get-port-number*()
            *else $pn*
};

cheers,
Jakob.
