mount cdfs....dishing pfsmount! Question...

[James Ellis_1]

I installed the patches to enable me to mount a Oracle CD without a pfsmount.

I did this:

mkdir /cdrom
mount -F cdfs -o rr /dev/dsk/c#t#d# /cdrom

Now, since its often Oracle has 4 sets of CDs to install, do I just do this to unmount the CDs and mount another CD?

umount /cdrom
(remove CD, and put in a new CD)
mount -F cdfs -o rr /dev/dsk/c#t#d# /cdrom

Was not sure if there was a special way to unmount the CD.

thanks.

You can just use 'umount' to unmount the CD in this case. Since it is the normal 'mount' command and the '-o rr' is an option, you use the normal 'umount' command.

Yes you can use the umount command to unmoutn the CD.

but remember NOT to cd to the oracle install directory and invoke the ORACLE INSTALLER.

# cd /cdrom/oracle/product/blah/blah
# ./installer

the above command will not let you unmount and change the CD when required.

# mount -F cdfs -o rr /dev/dsk/c0t4d0 /cdrom
# //cdrom/oracle/product/blah/blah/installer

1) Don't use pfs_mount its outmoded and you already have a better solution in the prior replies.

2) Do not mount the cd from the /cdrom or equivalent directory. That will leave on open process on the folder and it will be impossible to umount.

3) Commonly we mount the cd's properly and copy them to some scratch space and do the install from there. Its usually marginally faster, and if you have the space it uncomplicates the install. No cd switches.

just a few nuggets to chew on.
