Hi everyone, I am new in Oracle world. Yesterday morning we restarted our production box. The database came up without any problems. But because of a message from NetIQ we realized that Oracle has a little(?) problem with temp datafile, it seems that Oracle Temp datafile is not available for write. OEM console does not report any problems, the datafile size is 500mg and used %0. A NetIQ job (called "Oracle_TablespaceAvail") reports that 'An unknown Oracle error occurred'. Using OEM console I offlined and onlined the datafile, I added a new Temp (temp2 500M) datafile, offlined 1st datafile for almost 3 hrs, no difference at all. I switched them to online and after 24 hrs, Used % or Used (M) of Temp datafile is still 0. Questions: 1) Any idea why? 2) Is this a critical issue? 3) What is the solution?
