The generation of ORA-01034 and ORA-27101 is due to the fact that the database is not started and requires SYSDBA into the startup database.

@>conn sys/oracle as sysdbaConnected to an idle instance. [Email protected]>startupora-00600:internal error code, arguments: [Keltnfy-ldminit], [46], [1], [], [], [], [], [ ][email protected]>startupora-24324:service handle not initializedora-01041:internal error. Hostdef extension doesn ' t exist



The root cause of the above ORA-00600 is that the serverhostname is not properly configured and the hostname obtained by the hostname command cannot be ping. oracle10g think the host is unable to achieve so start database error.

Workaround: Add hostname to the/etc/hosts file. and Change/etc/sysconfig/network, keep hostname consistent. start the database again.
