我正在尝试从远程主机克隆一个 Oracle 12c 可插拔数据库，但我收到一个内部错误代码，几乎无法调试：

SQL> CREATE PLUGGABLE DATABASE CLONED_PDB FROM SRC_PDB@RCDB;
CREATE PLUGGABLE DATABASE CLONED_PDB FROM SRC_PDB@RCDB
                                                  *
ERROR at line 1:
ORA-00600: internal error code, arguments: [], [], [], [], [], [], [], [], [],
[], [], []
ORA-00600: internal error code, arguments: [], [], [], [], [], [], [], [], [],
[], [], []

两台机器都安装了 Oracle 12c，我对这两台机器都有管理员访问权限。我还可以在远程主机上进行本地克隆，这让我觉得这是一个文件权限问题，但我不知道我需要什么chmod。编辑后的脚本，在 SQL*Plus 中作为 sysdba 从 localhost 运行：

---------- REMOTE HOST ----------

-- Connect to remote host
CONN sys/password@//remotehost:1521/cdb0 AS SYSDBA

-- Drop existing user
DROP USER C##NEW_RCU;

-- Create user in remote PDB
CREATE USER C##NEW_RCU IDENTIFIED BY new_rcu;

-- Grant privileges to remote user
GRANT CONNECT, RESOURCE, DBA, CREATE SESSION, CREATE PLUGGABLE DATABASE TO C##NEW_RCU;

-- Connect to source PDB
ALTER PLUGGABLE DATABASE SRC_PDB CLOSE IMMEDIATE;
ALTER PLUGGABLE DATABASE SRC_PDB OPEN READ WRITE;
ALTER SESSION SET CONTAINER=SRC_PDB;

-- Grant create privileges to remote user
GRANT CONNECT, RESOURCE, DBA, CREATE SESSION, CREATE PLUGGABLE DATABASE TO C##NEW_RCU;

-- Connect to CDB
ALTER SESSION SET CONTAINER=CDB$ROOT;

-- Open source PDB in read-only mode
ALTER PLUGGABLE DATABASE SRC_PDB CLOSE IMMEDIATE;
ALTER PLUGGABLE DATABASE SRC_PDB OPEN READ ONLY;



---------- DESTINATION HOST ----------

-- Connect to destination host
CONN sys/password@//localhost:1521/cdb0 AS SYSDBA

-- Drop existing DB link
DROP DATABASE LINK RCDB;

-- Drop database if it exists
DROP PLUGGABLE DATABASE CLONED_PDB;

-- Create database link in root container
CREATE DATABASE LINK RCDB CONNECT TO C##NEW_RCU IDENTIFIED BY new_rcu USING '(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=remotehost)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=SRC_PDB)))';

-- DEBUGGING ONLY
SELECT SYSDATE FROM DUAL@RCDB;

-- Clone remote PDB
CREATE PLUGGABLE DATABASE CLONED_PDB FROM SRC_PDB@RCDB;

-- Open new PDB in read/write mode
ALTER PLUGGABLE DATABASE CLONED_PDB OPEN;

select sysdate from dual@rcdb除最后 2 个命令外，所有内容 - 包括- 都按预期工作。

知道如何调试这个，或者我可以尝试让这个克隆工作的任何步骤吗？
