I ass|u|me you are talking windows here. The access rights are not for you, but for the service. Go into the services startup/shutdown window and change the service to start as an account that has network rights to the mount point. I believe the services default to the "system account" whatever that is, and which has never worked for me. (see metalink doc# 211532.1 or do a metalink search on both your error numbers ORA-27040 & OSD-04002 ) Now for the issue of networked database files. I haven't looked at this issue in 5+ years but the way it used to work was that when a commit, checkpoint, etc. occurs that requires a guaranteed write to disk, Oracle does a "flush buffer" or some call like that in "c" (sorry, to long since I wrote "c" to remember) and the issue is that the call they use was/is not guaranteed over network drives. So you are running a risk of a corrupted database if some anomaly happens. Now hardware and networking have come a long way over the years and I'm sure there are configurations that handle this just fine. So you have to ask yourself, "does yours?".

Guys,

the env. is 8.1.6/win2k.

SQL > alter tablespace test add datafile '\\192.168.17.111\shared\test.dbf' size 100m;

ORA-01119: error in creating database file '\\192.168.0.111\shared\test.dbf'

ORA-27040: skgfrcre: create error, unable to create file
OSD-04002: cannot open file.
O/S-Error: (OS 5) access denied.

But i have all access/permission to this drive. i mapped this shared network drive and then tried once again. even then i get the same error.

Is it possible to create a tablespace with datafile residing in a shared network drive ??

TIA. Prem.
