[英]Oracle 12c RAC GV$SESSION EVENT column
I have an oracle 12c rac cluster with 2 nodes. 我有一个带有2个节点的oracle 12c rac群集。
If i execute this select statement: 如果我执行此选择语句:
select * from gv$session where osuser = sys_context('USERENV','OS_USER');
i will get 3 rows: 我会得到3行:
Is it a valid assumption, that, in this case the session with EVENT = 'PX Deq: Execute Reply' is always the query coordiantor? 是一个有效的假设,在这种情况下,EVENT ='PX Deq:Execute Reply'的会话始终是查询协调器?
Not sure about what you've provided above, but if you want to find the query coordinator for all parallel query operations, you can query v$px_session (or gv$px_session). 不确定上面提供的内容,但是如果要为所有并行查询操作找到查询协调器,则可以查询v $ px_session(或gv $ px_session)。 The QCSID column is the coordinator.
QCSID列是协调器。
