我在fzfw用户下用dbms_job包自动调度了其他2个模式下的存储过程的执行。fzfw是DBA用户。

告警日志报错：

手动在SQLPlus中调用执行(fzfw用户)：
SQL> exec olap.p_datetime1min_tmp;

PL/SQL procedure successfully completed.

创建一个测试存储过程(fzfw用户)：
SQL> create or replace procedure p_test
as
begin
  olap.p_datetime1min_tmp;
end p_test;  2    3    4    5
  6  /

Warning: Procedure created with compilation errors.

SQL> show error

SQL> grant execute on olap.p_datetime1min_tmp to fzfw;

Grant succeeded.

SQL> grant execute on fzfwapp.p_clear_tmrindb to fzfw;

Grant succeeded.

再次测试(fzfw用户)：
SQL> create or replace procedure p_test
as
begin
  olap.p_datetime1min_tmp;
end p_test;  2    3    4    5
  6  /

Procedure created.

通过DBMS_JOB再次调度fzfwapp.p_clear_tmrindb,olap.p_datetime1min_tmp这2个存储过程，运行正常。

结论：即使你是DBA用户，你要在存储过程中调用其他模式下的存储过程，必须手动使用grant语句把其他模式的存储过程的执行权限赋予该用户，方可在存储过程中调用其他模式的存储过程。否则就会报PLS-00201错误而无法调用。在这个例子中，我们可以认为dbms_job实现的自动调度也是类似于存储过程的方式来实现的。
