我试图使用 IMPDP 命令导入转储文件，结果出现以下错误：
ORA-31626: job does not exist
ORA-31637: cannot create job SYS_IMPORT_FULL_01 for user user1
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95
ORA-06512: at "SYS.KUPV$FT_INT", line 798
ORA-39244: Event to disable dropping null bit image header during relational select
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 86
ORA-06512: at "SYS.KUPC$QUE_INT", line 1825
ORA-04063: package body "SYS.DBMS_AQADM_SYS" has errors
ORA-06508: PL/SQL: could not find program unit being called: "SYS.DBMS_AQADM_SYS"
我在 oracle 论坛和谷歌上搜索了任何解决方案。不知道为什么会发生此错误。这与数据库配置有关吗？
