SAS 9.4 Grid manager for platform --cluster info

[sathya66]

Hi All,

Trying to access SAS 9.4 grid manager for platform via environment manager but can't see cluseter,hosts,jobs and ques info on the web page. See the screenshot below. How can we configure this. Everything is working except this.

This could be a starting point:

https://documentation.sas.com/doc/en/pgmsascdc/9.4_3.5/gridref/p0vmcshemrmkhvn1w9no6ktmhy4i.htm

It could also be that PWS itself is having problems. You can check in the SASServer14_1 logs to see if that gives you any clues.

[doug_sas]

This usually indicates that the Platform Web Services web app does not have access to the LSF cluster. Contact tech support to have them check out your deployment.

Do we need to run lsf services in Mid-tier or we just need an access to LSF Cluster ?

[gwootton]

The middle tier host must be configured as an LSF client, so you need to be able to successfully run LSF commands like lsid on the middle tier host for Platform Web Services (the web application that enables the SAS Grid Manger for Platform web application) to function

[sathya66]

Mid-tier is configured as LSF client but when configuring Mid-tier , I haven't started lsf services . Is it an issue? or we must start the lsf services on mid-tier before configuring mid-tier?
I just started lsf services (ex:lim) but I can't see the cluster,hosts ,jobs,etc info on the web page.

[gwootton]

No, LSF clients do not run LSF services, but are able to submit jobs and run other LSF client commands. Are you able to run lsid on the middle tier host successfully?

[sathya66]

yes, I can, see the results below

My master name is hostname

[doug_sas]

It could be that the LSF environment profile (profile.lsf) has not been sourced in the PWS web app server. If the LSF environment variables are not set, LSF commands will not work.

[sathya66]

LSF environment profile has sourced in PWS web apps server (checked my response file )

[gwootton]

You should check your server.log file and PlatformWebServices.log file for errors.

This error is usually from an issue with the LD_LIBRARY_PATH setting in the SASServer14_1/bin/setenv.sh file missing the versioned path. Make sure your LD_LIBRARY_PATH looks like this (both common and lsf10.1 paths, $LD_LIBRARY_PATH at the end), restart SASServer14 see if the error persists.

LD_LIBRARY_PATH="$GUI_LIBDIR/common/linux-x86_64/:$GUI_LIBDIR/lsf10.1/linux-x86_64/:$LD_LIBRARY_PATH"

Platform web services is a component that has to be deployed on SAS Mid-Tier node in one of the SASServerX_Y App servers. Once it's deployed and started, Mid-Tier node should be registered as a LSF client to the LSF Cluster so that it can query and run the necessary commands to display information on this UI.

Hope this helps!
