今天在查看bdump\cdmp\orcl2_p123_54321.trw的文件内容时,发现有"PX Deq: reap credit"等待事件,于是就到mos中搜索了一下:
WAITEVENT: "PX Deq: reap credit" (文档 ID 250947.1)
该等待事件的说明如下:
This wait event indicates that we are doing a non-blocking test to see if any channel has returned a message. We should see that although there is a high number of these events, the time accumulated to it should be zero (or really low).
