multiple sas spawners

aquadri — Fri, 22 Mar 2019 13:45:27 GMT

Hello,

We need to install two instances of sas 9.4 spawners on a single RHEL server. One for the users who are behind the firewall and another one for the users who are outside of firewall. If there is any document available to help us install multiple spawners please let me know.

Thank you

Aziz

One spawner per physical machine, but you can define multiple application server contexts on the same physical machine, using separate port numbers and different configurations.

Hello,

it’s possible to install more than one object spawner in the same host, I actually like to do it because granularity helps for maintenance and troubleshooting a sas app server without impact for the others.

Just beware that your WIP platform will be attached to 1 SAS app server. If some web apps, such as SAS studio allow execution in other sasapps that’s is a different story.

You will only need to deploy again with SDW, the SAS app server, selecting object spawner too. Very easy.

I have a question, though: since this design choice you are taking is related to a security split between internal and external users, what are the security setting you plan to split? This would help us to provide insights and perspective.

Thank you for the reply. I am working with Server Administrators who control our servers. I do not have admin rights for the server, I wish I had one, because the administrators do not understand SAS well and I have to passively and remotely work with them. To answer your question, we have separated the data in two directories. Few sas users on our campus work with some of our datasets. We created a separate directory for the outside users and they can only access that, where as we can access all the data.

Our Server administrators tried to run second spawner but following error msg is popping up. There is further text of mine after the below error message, please make sure to read that.

Administrators tried following commands

/soft_kits/sas94/SASFoundation/9.4/utilities/bin/cntspawn -mgmtport 4020 &

work.

/soft_kits/sas94/SASFoundation/9.4/utilities/bin/cntspawn -service spawnerp &

gives above error message.

If they hard code the port number using -mgmtport option there is no error message, but spawner doesn't seem to listen to the port.

Thank you
