curso sharing question

Hi, We have a vendor (helpdesk application) that is used by about 100 simultaneous users. This is a gui application and we do not have access to the sql code. The database is version 11.2.0.3 and running on SUSE11 Linux.

For this type of gui application, what should the cursor_sharing value be set to ? EXACT or FORCE ?
Thank you.

It is not the number of concurrent users but how queries are build, in particular, the use of bind variables vs. the lack of bind variables (hard coded values)

If the queries lack bind variables e.g. they have literals in the predicate then cursor_sharing=FORCE would be a sensible option.
