Hi Avni, just make a checkout of the xotcl-core package. If I remember correctly Gustaf mentioned it "should" work. Once xotcl-core is working in Oracle, XoWIKI should not be much of an issue, though you might have to wade through the /tcl directory and search for the SQL commands, but instantiate_sql_query (in XoTCL Core) should be smart enough to "only" return a working query string, unless it is overridden with the "-where_clause" parameter.

This all being said, I got it installed on Oracle after I cut down the description tag of xowiki.info as Oracle was complaining about "long" parameters.
