ORA-21561: OID generation failed

在工作中，使用sqlplus連線資料庫

SQL> conn system/oracle@depdb1
ERROR:
ORA-21561: OID generation failed

出現該錯誤後，檢視metalink

Connection Via 10.2.0.3 SQL*Net Fails With Error ORA-21561: OID Generation Failed [ID 559981.1]

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.

同時檢查自己的/etc/hosts檔案，確實存在這個問題，修改/etc/hosts後問題解決
