ORA-00600: internal error code, arguments: [keltnfy-ldmInit], [46], [1], [], [], [], [], []

SQL> startup nomount;
ORA-00600: internal error code, arguments: [keltnfy-ldmInit], [46], [1], [], [], [], [], []

产生这个问题的根本原因是服务器hostname没有正确配置，通过hostname命令得到的主机名无法ping通，Oracle10g认为主机无法达到所以启动数据库报错。

解决方法：将hostname添加到/etc/hosts文件中:

[root@node2 ~]# more /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1               localhost.localdomain localhost
::1             localhost6.localdomain6 localhost6
192.168.56.102 node2

再次启动数据库：

SQL> startup nomount
ORACLE instance started.
