Hello everybody,
currently I’m facing a strange Problem with a web + notes application residing on a pSeries as follows:
Creating a simple dblookup to another database to retrieve a list of projects works fine - for some 100 times.
Then I get a dblookup error file not found.
I face the problem whether I create a document from web or from notes. After 1++ more minutes everything works fine again - until the next blackout.
It seems, that the period the blackout occurs is becoming more frequently, the longer the server is running.
I assume it has something to do with upper case and lower case of the file names on OS level and if the result of the dblookup is served from the server cache or from drive.
Any help would be very appreciated.
Greetings
Stephan
Subject: File not found on AIX and dblookup
For a short while, I had a Domino server on Linux, and had similar problems.
It would seem that case sensitivity is indeed the problem. If someone, Notes or web client, access a DB with the correct case filename, Domino will then cache that filename. While Domino has that filename in the cache, it is not case sensitive, since Domino is not case sensitive. When the filename expires from the cache, the filename will have to be read from disk again, so it is once again case sensitive.
It could be that your dblookup has the wrong case in the filename of the DB, but when the DB has been accessed by someone else, the dblookup will work as long as the filename is being cached by Domino.
I could be way off here, but at least it’s something to check.

Hi Peter,
it was a problem with the dbcache of the server. I found a technote related to the topic and could reproduce the issue by simply setting up dbcache flush.
Thanks for your support
