    quick io

    Hi Friends,
    We have quick io enabled for all our datafiles in one of our database.
    Now i want to move some of the datafiles to other files system.
    How do i move the datafiles along with the quick io files.

    Do i need to disable them in the current location. Add them in the new location and move the corresponding datafiles to that location.

    Thanks in advance.

    regards

    he probably means Veritas Quick I/O for Oracle, sort of simulate direct i/o without using raw devices

    Yes you need to
    1)delete the soft links created by quick io.
    2)Move the datafile at the os level
    3)Recreate the soft links to the datafile

    To relocale the file do
    # ls -la
    shows the qio_test01.dbf and
    .qio_test01.dbf::cdev:vxfs:
    # rm qio_test01.dbf
    # cp .qio_test01.dbf
    /dbdist03/u04/oradata/djd1/.qio_test01.dbf
    # cd /dbdist03/u04/oradata/djd1/
    # ln -s .qio_test01.dbf::cdev:vxfs: qio_test01.dbf (note that ::cdev:vxfs: is just in ln command and tells filesystem to treat it as a rawdevice file, and you need verify that all : in link is correct. Compare with file created by qiomkfile command, Im pulling this from memory)
