RAC installation actual result unknown host exception has occurred error Solution

 

 

Install RAC clusterware. Two of them fail to pass the verification. The content is as follows:

 

Checking local cluster synchronization services (CSS) status...

Actual result: Unknown host exception has occurred: 60.191.124.236.

Check complete. The overall result of this check is: not executed <

Recommendation: Cluster synchronization services (CSS) provide services for single-instance Automatic Storage Management (ASM) in addition to being part of the Oracle clusterware stack. when configured stand-alone outside of the Oracle clusterware, it is sometimes referred to as "local" CSS.

 

Because you are installing Oracle clusterware on a set of nodes that already have local CSS configured, you must shut down any ASM instances and any databases using ASM and deconfigure local CSS on those nodes before proceeding with the Oracle clusterware installation. you can deconfigure local CSS by running 'localconfig delete' as the root user from Oh/bin. after the Oracle clusterware installation and configuration is complete, CSS will be started and configured to run from the Oracle clusterware home. you may then restart any ASM instances and any databases that use ASM.

 

 

Checking whether Oracle 9.2 RAC is available on all selected nodes

Actual result: Unknown host exception has occurred: 60.191.124.236.

Check complete. The overall result of this check is: not executed <

Recommendation: make sure that all the nodes are a part of Oracle 9.2 RAC environment before you install Oracle clusterware 10g Release 2.

 

The hostname and hosts configuration are not passed.

 

[Oracle @ qs-dmm-rh2 bin] $ CAT/etc/sysconfig/Network

Networking = Yes

Networking_ipv6 = No

Hostname = rac2

 

[Oracle @ qs-dmm-rh2 bin] $ CAT/etc/hosts

# Do not remove the following line, or various programs

# That require Network functionality will fail.

127.0.0.1 localhost

# Private network-(eth1)

192.168.1.42 rac1-priv

192.168.1.43 rac2-priv

 

# Public interconnect-(eth0)

192.168.2.42 Rac1

192.168.2.43 rac2

 

# Public virtual IP (VIP) addresses-(eth0: 1)

192.168.2.82 rac1-vip

192.168.2.83 rac2-vip

 

The original host hostname is a qs-dmm-rh2, not added to the hosts file, but I tried to write the qs-dmm-rh2 and the corresponding IP address to the hosts, and then run clusterware will still report an error. Finally, the qs-dmm-rh2 into rac2. run through.

 

Previously, when I installed RAC, the Server OS was also installed by myself. This time, the RAC server was installed by a colleague on the operating system. Some settings differ from my habits. The division of labor is too fine, and sometimes it is easy to understand.
