I would consider increasing the /u01. I have 10 gig for /u01 on my systems.

When and if you are reading to considering going to the next release ( for me 9.2 to 10.2 ... for you maybe 10.2 to 11.1 or 11.2 ? ) I find it handy to have the space already available for the next install of the next release/version. That way you don't have to fight for that space later.

Oracle is promoting heavily backing up to flashrecovery area which can be in a local file system or in ASM. Space usage for backups can vary but some people are advocating having 2 1/2 up to 3 times the space usage for your database available for backups. ( The most recent backup, the one before that, etc ). Received on Wed Nov 01 2006 - 08:13:23 CST
