AIX

Hi all,

I am a newbie to AIX. Can any one give me any idea of resource manager in AIX. How can i use it to schedule jobs at appropriate times. Any pointers to tutorials will b of great help.

I am not sure what you mean by "resource manager". In case you mean the "systems resource controller", "SRC": It is a facility to start/stop/restart system processes, which are usually called "daemons". For instance, the inetd is such a daemon/system resource, the lpd is one, etc.

AIX calls the services these daemons provide "subsystems" and puts them together in groups. Issue "lssrc -a" to list all the available subsystems, the group they belong to and their status.

Use "stopsrc" to stop such a system and "startsrc" to start one. There is also "refresh" which will restart a subsystem (usually in case one changed its configuration), but not all susbsystems can do a refresh - in this case you will have to "stopsrc" it, than "startsrc" it again.

A single subsystem can be started/stopped/refreshed with the parameter "-s":

Code:

startsrc -s sshd

will start the sshd, the secure shell daemon. You can also use the group relationship to start/stop/refresh a whole group of subsystems together with the "-g" parameter:

Code:

stopsrc -g nfs

will stop all the subsystems belonging to the "nfs" group and would be the same as issuing

Code:

stopsrc -s rpc.statd
stopsrc -s rpc.lockd
stopsrc -s biod

You can find the SRC itself running as a process by searching for "srcmstr" in the process list:

Code:

# ps -fe | grep src
    root  204928       1   0   Jan 07      -  0:00 /usr/sbin/srcmstr

You might want to get further information about the system resource controller here.

I hope this helps.

Hi bakunin,

Thanks 4 the response. Actually what i am looking for is some thing different. "Resource Manager" is a utility which is used to schedule programs to run at some date & time just like cron. It works by issuing a command "rmview". This opens up a interface where we can schedule our own programs and scripts to run at appropriate time. Any pointer to tutorials on this would b useful.

Does not sound like a specific AIX tool. From where do you have that? Does it come with documentation? Is it an open source tool?

You can try following to get more information about that rmview binary:

Code:

lslpp -l `which rmview`
# and check with
rpm -qf rmview

Maybe you're lucky to find what the package's name is and just google for it. Where the package comes from, there is usually documentation etc.

Thanks 4 the info
