20 Troubleshooting
When connecting to the database as a user other than oracle,
you receive the error messages ORA01034: ORACLE not available and
Linux Error 13: Permission denied.
This issue occurs when the required permissions are not set on the
remote node.
On all remote nodes, as user root, type: chmod 6751 $ORACLE_HOME
Installation
Oracle software fails to install on the nodes.
This issue occurs when the nodes’ system clocks are not identical.
Perform one of the following procedures:
• Ensure that the system clock on the Oracle software installation node is set
to a later time than the remaining nodes.
• Configure one of your nodes as an NTP server to synchronize the
remaining nodes in the cluster.
When you run root.sh, the utility fails to format the OCR disk.
This issue is documented in the My Oracle website under Bug 4679769.
Download and apply Oracle Patch 4679769 available on the
My Oracle Support website at metalink.oracle.com.
Networking
The cluster verification check fails.
This issue occurs when the public network IP address is not routable;
for example: 192.168.xxx.xxx
Assign a valid, routable public IP address.
