I haven't ran into that for Oracle, but I have for our Baan ERP application that runs on top of Oracle. We set just set the TZ environment variable as needed. Maybe you could adjust your TZ variable appropriately before starting each instance? -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx]On Behalf Of Loughmiller, Greg Sent: Thursday, July 28, 2005 11:29 AM To: 'Oracle-L@xxxxxxxxxxxxx' Subject: databases on same server with different timezones... Curious to see if anyone has a server, with multiple databases running where each database has a different TZ requirement(Pacific, Mountain, Central, and Eastern). And all databases on the server would use the same Unix acct (aka oracle). From what I can gather, Oracle uses the "gettimeofday" call to satisfy the request for a sysdate call. Thus, one would need to set the OS TimeZone appropriately since the DB would obtain the date/time from the OS... While I run thru the manual and metalink; I thought I would see if anyone on the list has had this experience......
