Hi all, Thanks for the feedback Greg and Faud, I noticed the feedback was not going to all on the list, so I thought I'd fwd it all: There's a job in the Job Library (in Grid): "DISABLE TABLESPACE USED (%) ALERTS FOR UNDO AND TEMP TABLESPACES" that's been setup to satisfy my requirement for UNDO and TEMP. Plus, ML Note: *How to - Exclude UNDO and TEMP Tablespaces From The Tablespace Used (%) Metric [ID 816920.1] discusses the same and hints at how to switch off alerting for other tablespaces using *DBMS_SERVER_ALERT.SET_THRESHOLD() So exactly what I was after, Thanks Tony* * -- //www.freelists.org/webpage/oracle-l
