Hi Jakob,
Debugging things on the task server can be a little tricky...
When you say manually it works, what do you mean? If you do an:
xdmp:invoke("/app/backend/update.xqy") it works?
The exception you are seeing can happen if the document /app/backend/update.xqy
is not loaded as a text document, or if the document cannot be found (or if
there is a permission issue causing it not to be found, but since you are
running as admin that should not be the case--assuming your admin user has the
admin role). So the first thing to verify is that the doistats-database
database has the app/backend/update.xqy document loaded as a text file.
For example, if you load a main module as follows, then you can confirm it is a
text document as follows:
xdmp:document-insert("/test/test.xqy", text {"'hello'"}) ;
if ( doc("/test/test.xqy")/node()
instance of text() )
then "text"
else "not text"
And yes, to change a scheduled task you must delete it and then recreate it.

Subject: [MarkLogic Dev General] scheduled task (task root?)
I've created a scheduled task in MLS 4.1. It does not run:
not with "/" as the task root
2009-08-08 21:32:00.106 Notice: TaskServer: XDMP-TEXTNODE:
/app/backend/upate.xqy -- Server unable to build program from non-text
document
2009-08-08 21:32:00.106 Notice: TaskServer: in /app/backend/upate.xqy [1.0-ml]
nor with "http://server:8004/";
2009-08-10 12:00:00.050 Notice: TaskServer: XDMP-TEXTNODE:
http://server:8004/app/backend/update.xqy -- Server unable to build
program from non-text document
2009-08-10 12:00:00.050 Notice: TaskServer: in /app/backend/update.xqy [1.0-ml]
manually, it works (of course).
I have searched the marklogic mailing list for discussions with this
kind of problem and only found one message from May 2008 which had
encountered this type of exception
(http://markmail.org/thread/nk26f2eizhqy3scy). In my case, it seems
to be a problem with the "task root" property of the scheduled task
which is explained in the help as follows:
"task root specifies the root directory (files [sic] system) or URI
root (database) that contains the module."
I'm in the latter case where the xquery sits in the
"doistats-database" database in the /app/backend/ directory. Or could
the problem lie somewhere else (permissions? I'm running this as admin
with all privileges)?
here are the task details:
task path: /app/backend/update.xqy
task root: /
task type: daily
task period: 1
task start time 9:32 PM
task database: doistats-database
task modules: doistats-database
task user: admin
task host: server
BTW, it seems a scheduled task cannot be modified, but only deleted?
(I filed a case with support@).
thanks,
Jakob.
