Hello,

on Webphere 9, Oracle 11, I've upgraded platform from 8.2.1 to 8.5.2.(typical in-place)

All is started as expected after adding the specific grant - GRANT SELECT ON SYS.V_$PARAMETER to yourDBUser; - https://collaborate.pega.com/discussion/engine-fails-initialize-after-clean-upgrade-pega-851-fixed

Agents are disabled. For testing purpose, I've set up node 1: Search,WebUser,BackgroundProcessing   node 2: WebUser, Stream On each node running in standalone or in cluster, the same exception is recurrently raised: DatabaseException caused by prior exception: java.sql.SQLSyntaxErrorException: ORA-00933: SQL command not properly ended (same was occurring with a single Universal node) First occurrence is during the startup itself

etc...

Typical logs then application is up. Then above similar error keeps being printed in logs.

I don't see what could be the reason for this (DB is fine, all grants & synonyms are fine). Issue with database table pr_sys_serviceregistry was already fixed This post is around the same following post but not providing solution: Error Getting Current Database time | Collaboration Center (pega.com))  Any clue?

Thank you
