ORA-31600:参数OBJECT_TYPE的输入值CHAIN无效

标签: oracle oracle11g export ddl dbms-scheduler

当我收到此错误时,我试图导出在Oracle 11g上创建的完整调度程序链(包括步骤,规则等):

ORA-31600: invalid input value CHAIN for parameter OBJECT_TYPE in function GET_DDL 
ORA-06512: at "SYS.DBMS_METADATA", line 5805
ORA-06512: at "SYS.DBMS_METADATA", line 8344 
ORA-06512: at line 1

消息含义

31600. 00000 -  "invalid input value %s for parameter %s in function %s"
*Cause:    A NULL or invalid value was supplied for the parameter.
*Action:   Correct the input value and try the call again.

查询失败:

select dbms_metadata.get_ddl('CHAIN','RUN_SERVICE_IP') from dual;

我们能够为链条导出(获取DDL)吗?导出整个链设置的替代方法是什么?

答案 0 :(得分:2)

Oracle 12c上的情况如下,我无法测试早期版本。

您需要将'PROCOBJ'指定为OBJECT_TYPE,因此:

select dbms_metadata.get_ddl('PROCOBJ','RUN_SERVICE_IP') from dual;

这适用于程序,作业和链。作业定义将包括属性。链定义将包括连锁步骤,但奇怪的不是连锁规则。这些只能从视图*_SCHEDULER_CHAIN_RULES中获取,例如

select 'dbms_scheduler.define_chain_rule(
  chain_name => ''' || chain_name || ''',
  condition => ''' || condition || ''',
  action => ''' || action || ''',
  rule_name => ''' || rule_name || ''',
  comments => ''' || comments || '''
);'
from user_scheduler_chain_rules;
