使用哪个命令察看solaris使用的是什么信号类型？

System V 还是其他的？
虽然可以看到设置了semmns,但有没有相关命令察看信号类型？？？

lonespappb33>cat  /etc/system | grep -i semmns
set semsys:seminfo_semmns=65535
set semsys:seminfo_semmns=65535
set semsys:seminfo_semmns=0x10100


谢谢

还有如何察看系统是否支持其他的信号类型  如post-wait driver?

“察看信号类型？？？”不明白所指。。。呵呵

但是如果说是查看哪些信号量起作用可以用系统命令
#sysdef -i

如果是定义的信号量没有起作用，不重启动的情况下可以
#modload /kernel/sys/semsys

就是oracle使用system V还是post-wait driver的问题，不过从链接里面没有找到对应的网页
Solaris semaphore mechanism  

--------------------------------------------------------------------------------
Yes, unfortunately Oracle are still using System V semaphores on Solaris despite the availability of POSIX semaphores. Have a look at Communicating the POSIX way for some interesting reading on POSIX semaphores under Solaris.

As you point out, Oracle have discontinued the Solaris post-wait driver in Oracle8. I\'m not sure why, but I presume that there was a good reason. Post-wait drivers are still available on some other platforms.


I was interested in your System V Semaphores vs. Posix discussion. But I have found out to my great disappointment that Oracle 8.x has obsoleted the POST_WAIT_DEVICE and USE_POST_WAIT_DRIVER parameters (According to OraDoc). Assuming you guys already knew this, did Sun and Oracle figure out the bugs/limitations and create a work-around?

看来solaris下oracle仅仅使用System V信号，但不知道如何察看系统支持多少类型的信号？
