Forum OpenACS Development: Re: A graphical installer for OpenACS & dotLRN

Posted by Nima Mazloumi on
Hi Vlassis,

OpenACS cannot start because of a database problem I get on Windows. This is what OpenACS tells.

[...The following database pools generated errors:

OpenACS could not allocate a handle from database pool "subquery".
Possible causes might include:

The database is not running.
The database driver has not been correctly installed.
The datasource or database user/password are incorrect.
You didn't define any database pools...]

Looking at the processes nsd and postgres are running. So what could be problem?

Hi Nima,
you will sometimes see that the error if nsd starts before the database is open. Try restarting nsd and see if that fixes it.

I often get that starting up dotLRN after a fresh reboot. I usually just killall then start up the respective server on my laptop.

Just another quick question: am I right in assuming the version of dotLRN this installation (v1.0.1) is .LRN 2.0.3 ?
I'm just asking in concerns to trying to develop a WYSIWYG text editor for forms, and have heard the setup is (much) quicker on .LRN 2.1.0 - yet to know if this is the case or not, but have been having issues with this on the Windows .LRN/OACS install (but it is fantastic work all the same)...

Cheers, Jon
