set SessionModule to FS

[Giulio Soleni]

Hi, I would like to increase the performances of OTRS and try to get rid of some annoying warnings in the log related to sessions.
For this reason I would change the SessionModule from DB to FS.
From the manual I can read

With "DB" the frontend server can be splitted from the db server.

... what does that actually mean?

And do you think is it safe to switch the SessionModule from DB to FS without harming the system ?

Thank you

it is safe to switch, just make sure that your webserver can write and read in your OTRS "SessionDir". it deafuls to <OTRS_HOME>/var/sessions.. if you switch, the current logged users will have to log in again.

Thank you eandrex, I will switch to FS at the earliest opportunity.
However still I do not know how should I interpret that "frontend server can be splitted from the db server" in the manual, and if this "split" may imply some side effects for example when I'll decide to update the system.

It means that if you're using DB for session management, the database server can exist on any accessible-to-the-OTRS-box server, therefore "split" from the web/front end interface. (Good for load balancing, perhaps). However, if you use filesystem/FS, your session management can (effectively) only be "local" to the OTRS server (mount-points aside).

Thank you crythias.
Since my OTRS system is one single box where everything is hosted on the same VM I think that I will definitely select FS session management.

you can also use a ramdisk like explained in the manual
