no ASMs are considerably different. Its supposed to manage everything. You dont give it a file, you give it entire disks and oracle does everything. Sets up files, manages, I/O, everything.
you only look at the tablespace level. you dont even install any software on it. If your on SAN, you dont install SAN software on it. > > From: "Goulet, Dick" <[EMAIL PROTECTED]> > Date: 2003/12/19 Fri AM 09:14:27 EST > To: Multiple recipients of list ORACLE-L <[EMAIL PROTECTED]> > Subject: RE: 10g new features question for beta testers > > That is not exactly a new feature.
