Oracle impdp的运行方式太长了
我试图将一个模式导入到一个oracle实例，这是运行在docker的容器（希望这是不相关的）。
我想为这个长期职位事先道歉，但是我想包括我已经查过的所有事情。
导入快速加载表，build立索引，但是当它进入包时，进程就停止。
日志输出停止这些行
Processing object type SCHEMA_EXPORT/VIEW/COMMENT Processing object type SCHEMA_EXPORT/PACKAGE/PACKAGE_BODY 它似乎卡在进程273，“改变包装…”

但是“ps agxu”显示进程273使用了大量的CPU

不幸的是我仍然看不出有什么问题。
从gv $ sessionselect没有行。
这里是gv $ sql的输出摘录。 它按last_load_timesorting，所以它应该显示正在进行的时间线。 ALTER PACKAGE仍然被标记为活动状态，但在三天内仅使用了182微秒，并且据我所见，没有recursionSQL语句，ALTER可能正在等待。

我感觉卡住了:-(
查找阻塞锁的最简单方法是查看会话。 通常情况下，最好的方法是查找谁阻止，而不是阻止什么 。
select * from gv$session where blocking_session is not null
ALTER可能正在等待一个recursion的SQL语句。 这些陈述并不总是被视为“封锁”。 运行此语句以查看正在运行的其他SQL。 如果你幸运的话，会有一个几乎和ALTER一样长的声明; 这将是下一个要调查的查询：
select elapsed_time/1000000 seconds, gv$sql.* from gv$sql where users_executing > 0 order by users_executing desc;
为了研究空间问题，最好查看DBA_RESUMABLE而不是特定的空间大小。 Oracle有很多方法可能会耗尽空间。 表空间可能看起来不错，但ASM或操作系统可能没有空间。
select * from dba_resumable;
基于更新，它看起来像导入的数据包含高级队列对象。 高级队列有额外的导入和导出限制 。 AQ的一切都是“特殊的”。 希望你的组织有一个专门从事AQ的人。 如果您需要为此问题创build支持请求，则不会感到意外。
