sqlplus连接数据库报ORA-21561: OID Generation Failed

Symptoms

After upgrading to version 10.2.0.x, SQL*Plus connections fail with the following error:

ORA-21561 : OID generation failed

ERROR:

ORA-21561 : OID generation failed

Enter user-name: <username>/<password> @ <tns connect string>

Connected to:

Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bit Production

Cause

Incorrect /etc/hosts mapping for the client machine or no mapping at all.

Solution

Check the client's /.../hosts file and verify that the local node is correctly identified with a mapping for both the short and fully qualified name of the host.

我遇到问题的原因是由于hosts文件的权限被改了导致的错误，权限改回去，再次连接正常
