HTMLDB - PlsqlNlsLanguage takes one argument, NLS Language

I installed HTMLDB (off the 10.2 Companion disk) on Solaris today. Install seemed to run OK and at the end it told me that the HTMLDB instance had started and could be accessed at:

http://wintermute:7778

When I tried to access it, no joy. Said it couldn't connect. I tried using opmnctl to check the status and found that opmn itself was up but none of the managed services were. Stopping and starting opmn and all it's managed processes produced:

$ opmnctl stopall
opmnctl: stopping opmn and all managed processes...
$ opmnctl startall
opmnctl: starting opmn and all managed processes...
================================================================================
opmn id=wintermute:6200
    0 of 1 processes started.

ias-instance id=IAS-X-wintermute.6299
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
ias-component/process-type/process-set:
    HTTP_Server/HTTP_Server/HTTP_Server

Error
--> Process (pid=24282)
    failed to start a managed process after the maximum retry limit
    Log:
    /u03/oraracle/app/oracle/htmldb/10.2/opmn/logs/HTTP_Server~1

Looking in the log file (see the updates to the wikipedia article on Error Hiding that I made for my views on error mesages and log files) reveled many instances of a more detailed error message:

--------
06/06/30 12:20:00 Start process
--------
/u03/oraracle/app/oracle/htmldb/10.2/Apache/Apache/bin/apachectl start: execing httpd
Syntax error on line 9 of /u03/oraracle/app/oracle/htmldb/10.2/Apache/modplsql/conf/marvel.conf:
PlsqlNlsLanguage takes one argument, NLS Language

leading me to the settings file marvel.conf. The contents of this file were:

<Location /pls/htmldb>
    Order deny,allow
    PlsqlDocumentPath docs
    AllowOverride None
    PlsqlDocumentProcedure wwv_flow_file_manager.process_download

    PlsqlDatabasePassword @BdtmwbdTRq8ljkMXfRPmbpw=
    Allow from all
</Location>

Looking at the indicated line, line 9:

PlsqlNLSLanguage ENGLISH_UNITED KINGDOM.AL32UTF8

the only thing that struck me was the space in the middle of the NLSLanguage identifier, maybe this was being intrepreted as a field seperator?

I put sigle quotes around the NLSLanguage identfier:

PlsqlNLSLanguage 'ENGLISH_UNITED KINGDOM.AL32UTF8'

and tried again:

$ opmnctl stopall
opmnctl: stopping opmn and all managed processes...
$ opmnctl startall
opmnctl: starting opmn and all managed processes...
$

Success!
