Congratulations on your change in status!

RE the mount points:  I'm still fairly OS illiterate with many
features of NT/Win2k.  Do you have a good URL that 
would explain the use of mount points?

Sorry for not being much help on this topic, but thanks
for sharing your experiences.

Jared

        Subject:        Win2K Mount Points


Hello,


I have been tasked to upgrade an existing Openserver 5 / 7.3.4 
installation to 
a Win2K / 8.1.7 installation. The hardware is an IBM 8500R 8-way with 4GB 
main 
memory and 32 mirrored pairs.

Under Unix it is simple to mount each filesystem at an appropriate mount 
point. 
However, the traditional method of using drive letters in Windows is 
somewhat 
limited by the number of available letters. The obvious solution with 
NTFS5 is 
to use mount points - which is what I have done. I have a directory 
located in 
$ORACLE_BASE under which I have mounted 25 of the mirrored pairs, i.e. all 
of 
the filesystems that will be used exclusively by Oracle

Currently, the Openserver installation is still live and I am configuring 
the 
Win2K installation on identical h/w for a period of testing. Whilst I have 
had 
not had any issues with using NTFS5 mount points, I have been scratting 
around 
trying to find real-world experience of such a configuration. The official 

Oracle line (via an iTAR that I filed) is that as the base OS is fully 
supported, i.e. supported without certain features being excluded, the use 
of 
mount points is okay. However, should I observe any issues with such a 
configuration then any queries should be directed to Microsoft.

The response is fair enough, I guess, but it didn't provide what I was 
asking 
for. Therefore, I would like to ask the wider audience if they have any 
experience of such a configuration, i.e. any known issues with NTFS5 mount 

points in general, the number that is "safe" to use beneath a base 
directory, 
recovery issues etc.

I should point out that the application data that is stored in the 
database is 
roughly 80% static and 20% "hot" and in the ideal world the static data 
could 
be stored on a smaller number of larger arrays to allow the h/w to do most 
of 
the load balancing. However, I have no say in h/w matters so this isn't 
really 
an option for me.

Finally, as this is my first post to the list, perhaps I should introduce 
myself as a lurker(!): I have enjoyed following the various discussion 
threads 
on a daily basis. The collaboration of people helping each other with 
common 
issues and the willingness to share expertise etc makes ORACLE-L a 
powerful 
resource.

Many thanks.
