@>conn sys/oracle

ERROR:

ORA-01034: ORACLE not available

ORA-27101: shared memory realm does not exist

Linux Error: 2: No such file or directory

产生ORA-01034和ORA-27101是由于数据库没有启动，须要有sysdba进入启动数据库。

@>conn sys/oracle as sysdba

SYS@TEST0422>startup

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

SYS@TEST0422>startup

ORA-24324: service handle not initialized

ORA-01041: internal error. hostdef extension doesn't exist

产生以上ORA-00600根本原因是serverhostname没有正确配置，通过hostname命令得到的主机名无法ping通。Oracle10g觉得主机无法达到所以启动数据库报错。

解决方法：将hostname加入到/etc/hosts文件里。而且改动/etc/sysconfig/network，让hostname保持一致。又一次启动数据库。

[root@rtest ~]# vi /etc/sysconfig/network

NETWORKING=yes

NETWORKING_IPV6=no

HOSTNAME=rtest.localdomain

[root@rtest ~]# vi /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

之前是192.168.1.161 ocm1.localdomian ocm1
