AIX 5L学习总结4
1.管理子系统
子系统全部由SRC(Resource System Controller)系统资源控制器
-bash-3.00$ ps -ef|grep srcmstr //查看SRC的守护进程
root 204974 1 0 Jan 03 - 0:02 /usr/sbin/srcmstr
enjoygoo 2261074 1949916 0 15:31:29 pts/92 0:00 grep srcmstr //srcmstr在进程/etc/inittab文件中一条记录
-bash-3.00$ cat /etc/inittab |grep srcmstr
srcmstr:23456789:respawn:/usr/sbin/srcmstr # System Resource Controller//这条就是记录
如果没有这条可以用mkitab -i fbcheck "srcmstr:2:respawn:/usr/sbin/srcmstr"
SRC有一组管理子系统的命令分别为
-bash-3.00$ lssrc -a //查看子系统、子系统组或子服务的状态。
Subsystem//子系统名字 Group//子系统所属的子系统组 PID//这个子系统的进程号 Status//状态
muxatmd tcpip 106652 active//表示子系统正常运行

2.startsrc命令启动其他子系统或子服务器
startsrc [ -a Argument] [ -e Environment] [ -h Host] { -s Subsystem | -g Group}
To Start a Subserver
startsrc [ -h Host] -t Type [ -o Object] [ -p SubsystemPID]
启动nfs中的所有子系统
-bash-3.00$ startsrc -g nfs
要启动一个web服务器
-bash-3.00$ startsrc -s httpd
也可以用smit startssys来启动子系统
Start a Subsystem
Type or select a value for the entry field.
Press Enter AFTER making all desired changes.
[Entry Fields]
* Subsystem Name +
3.用stopsrc命令向SRC发送一个请求，停止一个子系统或子系统组，或者停止所有的子系统。
Syntax
To Stop a Subsystem
stopsrc [ -h Host] [ -f | -c] { -a | -g Group | -p SubsystemPID | -s Subsystem }
To Stop a Subserver
stopsrc [ -h Host] [ -f] -t Type [ -p SubsystemPID] [ -P SubserverPID | -o Object]
-bash-3.00$ stopsrc -a//停止所有子系统

Stop All Subsystems
4.refresh命令用来给像子系统或子系统组这样的SRC资源发送重启启动请求。
