start_udev導致監聽自動停止問題處理

APPLIES TO:

Oracle Database - Enterprise Edition - Version 11.2.0.3 and later
Linux x86-64

SYMPTOMS

Dynamically added new disks to storage using udev rules(as per the docs note 414897.1, 1528148.1, 371814.1 etc).

During start_udev, udev has deleted the public network interface and this caused the listener to crash, and clusterware moved all services, scan listeners and the VIP on node 1 to node 2.

CHANGES

 Trying to add disk to storage using udev

CAUSE

 udev has deleted the public network interface.

SOLUTION

As per RHEL you are advised to set HOTPLUG="no" for the network configuration scripts.

Add HOTPLUG="no" to the ifcfg-eth0 (public), ifcfg-eth1 (private) and ifcfg-eth2 (backup) network config files in /etc/sysconfig/network-scripts directory.
