The java hotspot exception details in the hs_error_pid.log for failed call stack may be similar to the sample below:

======================snip============
j oracle.net.common.NetGetEnv.getDNSDomain()Ljava/lang/String;+0
j oracle.net.ca.ConfigureProfile.setDefaultProfileParams()V+0
j oracle.net.ca.InitialSetup.setupConfigObjects()V+204
j oracle.net.ca.InitialSetup.([Ljava/lang/String;)V+874
j oracle.net.ca.NetCA.main([Ljava/lang/String;)V+366
========================snip==================

 

Cause

NetCA fails to launch if hostname entry is missing from /etc/hosts file.

Problem may also be caused if the host server is using DHCP and there is no corresponding entry in DNS for the hostname resolution.

Solution

-- To implement the solution, please execute the following steps::
Customer reports the NetCA problem cleared after adding hostname entry in the /etc/hosts file.

For example:

celclnx123.us.oracle.com

[celclnx123]/amer/net/home> more /etc/hosts

127.0.0.1 localhost.localdomain localhost
10.110.3.100 celclnx123.us.oracle.com   << Add a line for the Linux Server's hostname[[email protected]]$ netca

这个问题是今天早上遇到的这里备记下。此外在实际操作是需要先：

#hostname -----确认主机名

也可以查询  /etc/sysconfig/network 里查看

修改主机名
        vi /etc/sysconfig/network，修改HOSTNAME一行为HOSTNAME=主机名，重启后才能生效
 

当然要配置主机名也少不了  /etc/hosts
