Hi, When I tried to track down xwiki 4.1's failure to upgrade the 3.5.1 (Oracle) database, I discovered that xwiki is trying to use the package SDO_GEOR_DEF. However, in a normal Oracle database, this package is owned by user/schema MDSYS and no synonym exists for it. Since xwiki is addressing the package only as SDO_GEOR_DEF and not MDSYS.SDO_GEOR_DEF, in order to make the call work, a synonym SDO_GEOR_DEF needs to be defined pointing to MDSYS.SDO_GEOR_DEF. I can not find this anywhere in the documentation, so I suggest an update to the documentation or a code change in xwiki. It should be pointed out, however, that a fix to this did not solve the original problem. /Lars -- View this message in context: http://xwiki.475771.n2.nabble.com/xwiki-on-Oracle-calls-package-SDO-GEOR-DE… Sent from the XWiki- Users mailing list archive at Nabble.com.
