Is there a method to restart object spawners on all GRID nodes via command from master node?

dgower — Thu, 27 Aug 2015 12:46:02 GMT

Hi All,

We have a GRID environment with 7 compute nodes. It's tedious to remote into each node and restart the object spawner service. Is there a command to use from the master node or an option SAS Management Console that will restart that service on all nodes?

Thanks,

Dan

Hi ,

You can write a script to start/stop SAS services , remotely , see SC ( Service Control Manager ) for Windows environment.

You need a script something like this

#! /bin/ksh

action=status # Or pass as $1 parameter

remotepath=/opt/sas/ServerConfig/Lev1/SASApp # For example

for node in node1 node2 node3 node4 node5 node6 node7 ; do

$ ssh sasaccount@hostname "$remotepath/ObjectSpawner.sh $action"

done

You will need to create an ssh key pair and put the ssh public key in $HOME/.ssh on each node first then test ssh to each node from sasaccount@masternode

I know this is an old post but I am following a similar path to do regular status checks.

I am passing paths, values etc in ksh to ssh into several servers to check the ObjectSpawner status:

ssh -tt $servernm ksh -c "$Path/ObjectSpawner.sh status" >>/folder/objectspawners.txt

All I get in my text file is a lovely : Usage: ObjectSpawner.sh {-}{start|stop|status|restart}

What I should see is a "ObjectSpawner is started"

Why does it not read my "status" param?

If you remove the "ksh -c" part, does it work?

Would suggest developing simple Ansible playbooks to automate admin tasks!
