    If I want to mount the subdir with cio option, do I have mount it before I install the application using the subdir or after the installation? I tried to reinstall my Oracle 10g R2 (10.2.0.1) on AXI 5.3L, but tried one yesterday and it was very slow. That was not like such 2 months ago, when there was no cio option for the subdir.


  • 2.  Why would you do that???

    Hi,
    I don't see any point in mounting your Oracle code as CIO.

    The problems is CIO is likely to be very slow and this blocks the use of the filesystem cache which normally speeds up general I/O a great deal - as you have found.

    You should use CIO only for database data files and the directories they are in.

    Hope this helps, N
