Hi All,
xdmp:http-head(..) will return code as 200 & message as "OK" only when we hit
HTTP Servers. For XDBC server & WebDav servers it will always return 404/Not
Found.
"xdmp:host-status(xdmp:host())//*:port" will all ports used in MarkLogic
server only.
For example:
I have following app servers with authentication scheme as "digest", you can
test this with any auth scheme (I tested for all).
1- Http server (cms_http) running on port 8007
2- Xdbc server (cms_xdbc) running on port 8003
3- WebDav server (cms_webdav) running on port 8006
4- Http server (content_http) running on port 8005
Used the following>>
declare function local:get-port-status($authScheme as xs:string?,
$port as xs:string?,$userName as
xs:string?,$password as xs:string?)
{
xdmp:http-head(fn:concat("http://localhost:",$port),
<options xmlns="xdmp:http">
<authentication method="{$authScheme}">
<username>{$userName}</username>
<password>{$password}</password>
</authentication>
</options>)
};
try{
local:get-port-status("digest","8007","admin","passw0rd"),
local:get-port-status("digest","8003","admin","passw0rd"),
local:get-port-status("digest","8006","admin","passw0rd"),
local:get-port-status("digest","8005","admin","passw0rd")
}catch($e){
$e
}
Response is:
<results warning="more than one root item">
<response xmlns="xdmp:http">
<code>200</code>
<message>OK</message>
<headers>
<content-type>text/html; charset=UTF-8</content-type>
<server>MarkLogic</server>
<connection>close</connection>
</headers>
</response>
<response xmlns="xdmp:http">

<headers>
<content-type>text/html; charset=utf-8</content-type>
<server>MarkLogic 5.0-1.2</server>

</headers>
</response>
<response xmlns="xdmp:http">
<code>404</code>
<message>Not Found</message>
<headers>
<content-type>text/html; charset=utf-8</content-type>
<server>MarkLogic</server>
<connection>close</connection>
</headers>
</response>
<response xmlns="xdmp:http">

<headers>
<content-type>text/html; charset=UTF-8</content-type>

</results>

what do you think? seems to work quite nicely.
let $port := xdmp:random(65535 + 8003) + 8003 (: yes, let's force ports above
8003 :)
return
try {
if (xdmp:http-head("http://127.0.0.1:"; || $port)) then
(: try again :)
else
$port
} catch($e) {
$port
}
cheers,

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,

Subject: [MarkLogic Dev General] how can i check whether an appserver
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.
