Hi,=20 If your underlying OS supports it, of course you can grow the raw device( in most modern OS, it is raw Volumns). Here is an example: -bash-3.00# vxassist -g testdg make testrawvol 100m=20 -bash-3.00# vxedit -g testdg set user=3Doracle testrawvol [oracle@ebaysha2**ora10g]$sqlplus=20 SQL*Plus: Release 10.1.0.3.0 - Production on Sat Apr 23 00:25:36 2005 Copyright (c) 1982, 2004, Oracle.
