Hello, I'm trying to install Oracle 10g RAC on OEL Linux 5 using VmWare. But getting the following error. “the location /dev/sdb1, entered for the oracle cluster registry (ocr) is not shared across all the nodes in the cluster….”. I checked the ownership and permissions are correct. And also zeroed the /dev/sdb1. If you know any solution, or any reference for installing Oracle 10g RAC on OEL Linux 5 using VmWare will be appreciated. Thanks in advance. Regards, SYED. -- //www.freelists.org/webpage/oracle-l
