Hello all having some problems that I can't see the reason for ... I've gone through the installation of the clusterware with OUI. Then, when asked to run root.sh, following happens: ./root.sh WARNING: directory '/opt/app/oracle/product' is not owned by root Checking to see if Oracle CRS stack is already configured Setting the permissions on OCR backup directory Setting up Network socket directories PROT-1: Failed to initialize ocrconfig Failed to upgrade Oracle Cluster Registry configuration The "not owned by root" can be ignored.

However, they're readable and writable: --- 40 # dd if=/dev/emcpowerr of=/tmp/test bs=1024 count=1024 1024+0 records in 1024+0 records out --- 41 # dd if=/tmp/test of=/dev/emcpowerr bs=1024 count=1024 1024+0 records in 1024+0 records out For some reason, during the install of the software, when asked to enter the names for the OCR disks in OUI, the owner needed to be oracle:dba. So it was. Now, after root.sh exits, the owner is changed to root. I don't see any evidence of a chown inside the scripts called by root.sh -- so it must be the binary doing this (????) Checking on another, working install of 11g, the owner is oracle:dba (which makes sense). Any ideas on what else I could check ? Opening an SR as we speak, but perhaps someone else has fallen down this pit before :) Cheers Stefan ========================= Stefan P Knecht CEO & Founder s@xxxxxxxx 10046 Consulting GmbH Schwarzackerstrasse 29 CH-8304 Wallisellen Switzerland Phone +41-(0)8400-10046 Cell +41 (0) 79 571 36 27 info@xxxxxxxx http://www.10046.ch =========================
