Linux下使用ps命令来查看Oracle相关的进程

Linux下可以使用ps命令来查看Oracle相关的进程


Oracle Listener

这个命令会列出Oracle Net Listener的进程


  1. [oracle@ www.linuxidc.com ~]$ ps -ef | grep tnslsnr

eg.ora_pmon_mc3yd213 is PMON process,PMON (Process MONitor) is an Oracle background process created when you start a database instance. The PMON process will free up resources if a user process fails (eg. release database locks).

这些后台进程,从数据库里也是能查到的,可以使用下边这个SQL来查后台进程,在program列中,你就能看到SMON,MMON,CKPT,PMON,MMAN,MMNL…后台进程


  1. select * FROM v$session WHERE type =‘BACKGROUND’;  
select * FROM v$session WHERE type =’BACKGROUND’;
关于后台进程,可以参见Oracle Background processes
