Hello George, One thing to keep in mind with ASM is that all LUNs in your disk groups must be of equal size. So if you use, say, 100 GB LUNs with ASM. Then when your database needs more storage, you'll need to add a 100 GB LUN to your disk group. There was an interesting presentation on ASM on http://www.oracleracsig.org. Do a search for %ASM% in the documents section of the site. HTH, David -- //www.freelists.org/webpage/oracle-l
