Hi, I am trying to get my head around exactly what Oracle ACFS and ADVM are in relation to ASM ( the Oracle manuals are less than clear ! )
Q1. To my mind, ACFS extends the ability of ASM to manage and present file systems which are not simply provided from a single server but where a file system itself could be distributed over a cluster of servers - is that correct ?
Q2. ADVM on the otherhand is stumping me a bit. I know that ACFS sits on top of ADVM but I am trying to workout what ADVM gives you above the usual volume management capability of ASM in the first place ?
Q3. What is ASMLib for ?
Q4. I believe oracleasm is the command line interface to ASMLib - is that correct ?
any help would be warmly appreciated,
Jim
