If this application is a PeopleSoft, then you can only convert temporary working storage tables to GTTs if the application is not restartable. Otherwise, it expects to find data in the tables from when the process crashed, so that it can continue from the last commit point. regards _________________________ David Kurtz Go-Faster Consultancy Ltd. tel: +44 (0)7771 760660 fax: +44 (0)7092 348865 mailto:david.kurtz@xxxxxxxxxxxxxxx web: www.go-faster.co.uk Book: PeopleSoft for the Oracle DBA: http://www.psftdba.com <http://www.psftdba.com/> DBA Blogs: PeopleSoft: http://blog.psftdba.com <http://blog.psftdba.com/> , Oracle: http://blog.go-faster.co.uk <http://blog.go-faster.co.uk/> PeopleSoft DBA Forum: http://groups.yahoo.com/group/psftdba _____ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Goulet, Richard Sent: Monday, June 08, 2009 3:10 PM To: walid_alkaakati@xxxxxxxxx; oracle-l@xxxxxxxxxxxxx Subject: RE: Global temporary tables with No logging Importance: High If these are global temp tables then their are not the cause of your increased archive log activity. Global temp tables have a default of the temp tablespace and are never logged. The reason is that once a session using a global temp table ends the table drops all of it's data & storage. Transaction preservation of global temps is per their definition. Refer to : http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/statements_70 02.htm#i2095331. It's fro 11g, but still applicable to 10g. You can specify nologging with the "alter table" command, but that can be overridden if the database has supplemental logging turned on as in there exists a physical standby. The biggest thing is to check with the application developers of provider. Some apps like PeopleSoft create "temporary" tables that are there to pass data between sessions in a batch job. If that's so, your stuck with them. If not consider rebuilding them as global temps.
