Hi all Has anybody had to consolidate a number of databases from servers with disparate server timezone settings to a single platform - either RAC or 12c plugin databases. It seems to me that every database application under the sun makes liberal use of sysdate and/or systimestamp and so relies on the underlying server o/s timezone. if you have had this issue, what did you do? Alternatives that seem viable to me. - listener per timezone for cases where the code originates at a remote client. - reduced number of consolidation platfotrms - one per timezone. -- Niall Litchfield Oracle DBA http://www.orawin.info
