Home -> Community -> Mailing Lists -> Oracle-L -> Sizing Raw Vols and Oracle Datafiles
Folks,
Have a question regarding sizing raw volumes and Oracle datafiles. I'm using Veritas 3.1, Solaris 2.6 and Oracle 8i (R2)
This is what I did. Using Volume Manager, I resized a raw volume from 1GB to 2GB (the raw volume belonged to an Oracle datafile). I then went into Oracle and did a alter database datafile 'temp.dbf' resize 1999M. I did this after making sure that the raw volume had enough room to grow and that it would not overwrite any other volumes.
When discussing this with an SA, he said that he has never done this or has been asked to do this either in an Oracle shop or Sybase shop. He's been told by other DBAs' that this should never be done and it is best to add new volumes and then do 'alter tablespace add datafile ...'. I was unable to get an answer as to why this is bad and should'nt be done.
So, my question is, is this a myth; can it done and if not, what is the reason for not doing this?
Any opinions or facts?
Thanks
mkb
