Restarting SAS OB. SPAW while jobs running

Hello Folks, 

Please help with your feedback,

 

we have situation where web application seems down (not responding) (we use web application to monitor jobs and files) at same time we have long jobs running. Is it okay to restart Object Spwner while jobs running on server since to get back web app? we don't want to disturb on going long running jobs and at same time we want web app back becasue its critical. 

 

also, just to know, is it okay too to restart Object Spawner to get desktop app back just in case if SAS EG is down? 

 

Thank you....

Do you use LSF or some other tool to schedule the jobs ? That will reduce the complexity. 

 

The Object spawner listens for requests and start the workspace server or storedprocess servers sessions if necessary. 

 

As long as those running jobs does not expect to launch new sessions of these during the resart , it should be alright.

Hi @woo,

 

as @userid007 well indicated, neither your long running processes (single jobs) or your web applications will suffer if you restart the object spawner of a SAS Application Server.

 

Given the case you do this for EG, yes, it will recover the desktop apps and open EG sessions with no running processes will "suffer", meaning your users will need to reconnect (if EG do not reconnect by itself) and the current WORK and UTILLOC items will be lost. Therefore, I would recommend you get an agreement with your EG users about how to proceed on those cases.

Thank you so much userid007 and JuanS_OCS for your input/comment. I GOT MY ANSWER Smiley Happy 

 

We do not use LSF, we have UNIX environment and we have IBM tool (Tivoli) where all jobs implemeneted. I wish we would have GRID environment Smiley Happy.
