Webinator HTTP 500 errors

Hello,

We found the following entries in our IIS log files.

I think the 500 near the end of the the last line means there was an HTTP 500 error. Does that mean the webinator is generating the 500 error?

Thanks.

I don't know IIS log format, but if that 500 is HTTP error then it would seem so. Check vortex.log to see if there's anything logged there for the same time.

Yep, I'm getting "permission denied" errors, and "no SYSTABLES in the function ddopen" errors. Why would we get these?

From the log it looks as if the search result page has a link to /scripts/texis.exe/Webinator with no script name. This may be due to a relative link in your look and feel. Judging by the number of fetches preceding it with the same referrer it may also be a web accelerator gone amiss.

john208 · Post by **john208** » Fri Jan 13, 2006 10:56 am

We use <form method="get" action="/SCRIPTS/texis.exe/Webinator/search">

Is this correct? Are you saying sometimes we just have action="/SCRIPTS/texis.exe/Webinator" without the search?

What about the permissions error? Why would we only sometimes have a problem with permissions?

Thanks, John

/Webinator is a directory not a file.

Does the database and directory mentioned (D:\Texis\Altamont\db2) exist?

Post by **John** » Fri Jan 13, 2006 10:58 am

You either have an action without the search on the end, or possibly a relative link in the look and feel that would end up without the search. In anycase the permission errors are because you can't open a directory as if it were a file.

Aha. I have a D:\Texis\Altamont\db2 folder but it is empty. The db2.long file contains:

<pre>
Webinator Walk Report for Altamont

Creating database D:\Texis/Altamont/db2...
100 C:\Program Files\Thunderstone Software\Webinator\texis\scripts/Webinator/dowalk(createdb) 1752: License Violation in the function createdb

002 C:\Program Files\Thunderstone Software\Webinator\texis\scripts/Webinator/dowalk(maketables) 1808: can't open D:\Texis\Altamont\db2\: no SYSTABLES in the function ddopen

000 C:\Program Files\Thunderstone Software\Webinator\texis\scripts/Webinator/dowalk(maketables) 1808: Could not connect to D:\Texis/Altamont/db2 in the function openntexis

...

So it seemed Webinator tried to create db2 earlier this week and failed. Usually the search uses db1 but sometimes it uses db2. How did this happen and what do I do now?

Try removing the db2 directory completely so it'll get recreated.

Also run
texis -license
from the dos prompt to check your license status and if you're still in violation. If you're in violation don't expect much to work right.

In the vortex.log, I see "License Violation in the function createdb" starting 12/18/2005. We got a new copy of our licence 12/15/2005. That was to remove the copyright comment from the results page because those comments were causing issues with our css. 12/18 was the first time we tried to start a new walk.

Every time the License Violation occurs, the empty db1 or db2 folder is created with the above errors. So basically we can't start a new walk anymore. Sounds like there is a problem with the license file that was sent to us on 12/15.

Here is the output.
