Not according to the OACS installation instructions, and not how I have it running on another box:
SVRMGR> exit
joeuser:~$ su -
Password: ************
root:~# mkdir -p /ora8/m02/oradata/ora8/
root:~# chown joeuser.web /ora8/m02/oradata/ora8
root:~# chmod 775 /ora8/m02/oradata/ora8
root:~# exit
joeuser:~$
I did get around the problem by changing permissions on the directory to 777 just to complete this step, but now have problems that suggest errors with jvminst. So looks like starting over is the next step.
Thanks.
