[xwiki-users] Privileges on Oracle database

Hello! I have a question regarding the installation of XWiki. In the installation instructions it says I must type these commands: connect ... create user xwiki identified by xwiki; grant all privileges to xwiki; However this wiki will be installed on a corporate network on their database and application servers and therefor not possible to grant all privileges to xwiki. I wonder if it is possible to run the wiki with more restrictions on the user xwiki? Which privileges is enough for xwiki to operate on the database correctly? Thanks for your time and patients. I will be happy to hear from you again Anders Andersson
