PROCMGMT: Oracle数据库"Blocked on Streams"
问题描述
我正在运行Oracle数据库,Glance报告它花费了50%的时间“Blocked on Streams”。
这个词表示什么意思?
配置信息
操作系统 - HP-UX
版本 - 11.0
硬件系统 - HP 9000
系列 - K370
应用程序 - Oracle
解决方法
你在HP-UX 11.00中所看到的流I/O等待是你在HP-UX 10.20中看到的旧的套接字I/O等待。
显然,从HP-UX 10.30开始内核网络层进行了修改,现在使用基于流的IPC。
Glance只是反映这种变化。

Solution
The streams I/O waits that you are seeing in
HP-UX 11.00 are the old socket I/O waits that
you saw in HP-UX 10.20.
Apparently the changes were made from HP-UX
10.30 onwards in the networking layer of the
kernel, which now uses streams-based IPC.
Glance is simply reflecting this change.
