SAS servers start sequence

SASJR1 — Tue, 17 Nov 2020 12:55:56 GMT

Hi, I have an environment so I have three servers stand-alone Metadata server,Compute Server, and Middle tier server. I want to perform de-flashing/upgrade SAS9.4M6 to SAS 9.4M7 because of this :

I do the system evalution and fix those issues on Middle tier then when I do the Compute and re-start compute services and try to load the web portal again I does not load.

Is there a specific way I can get the order on starting those services or anyone here has done de-flashing/upgrade.

I would appreciate if you share your experience. Thank you in advance.

Hey @SASJR1 ,

Starting order of servers: First stop your Midtier, next Compute Tier and then Metadata server & Starting in the reverse order - https://go.documentation.sas.com/?cdcId=bicdc&cdcVersion=9.4&docsetId=bisag&docsetTarget=n1fxn02xr08732n1p0kph4z4145t.htm&locale=en For multi-tier environments there is also this: https://support.sas.com/kb/58/231.html

In order to install SAS 9.4 M7 you should contact your contact at SAS and request a SAS 9.4 M7 Software Depot and either do an upgrade in place or install in a new environment and migrate your content. Take a look at this thread (https://communities.sas.com/t5/Administration-and-Deployment/Upgrade-in-Place-Steps/td-p/444848) for documentation links and tips.

Kind regards

David

@SASJR1 - What OS are you on? If it is Unix then SAS provide a script for starting and stopping servers in the correct sequence. I'll see if I can dig out a reference to it if required.

@SASKiwi Hi.

My OS is Windows server 2016. on that script for Unix, you can not modify it or use it on Windows OS.

@DavidHD Hi,

I tried the links you shared thanks. Still not winning even got this one on my search https://go.documentation.sas.com/?cdcId=bicdc&cdcVersion=9.4&docsetId=bisag&docsetTarget=p0d9d5nzmd8i4yn1usv2l22vpa7t.htm&locale=en#p0d5wrx6q3v3jln11pl4fs5cbyzq

I will see if I'm winning here guys!

Regarding SAS9.4M XXXX maintenance, currently running SAS9.4M6 and I have SAS9.4M7 that I want to update.

Did you take a look in the server logs? Maybe one of the services is unable to get up because of errors

Re: SAS servers start sequence

I have noticed that other services were not running for example on COMPUTE, DIP service and SAS deployment tester was not running so is it the right thing to start a service manually DavidHD because I didn't want to corrupt the whole system or environment. and Yes the logs is the first thing I check.

Do be honest I'm not sure if this will corrupt the system or not, it shouldn't but I'm not certain.

But the questions I have are:
- Can you connect to the Metadata Server?
- Can you start a SAS session via a client like EG?
- Can you excess any other Web-Apps?
- If not can you at least access Logon Manager?

Don't give me wrong all services should be running but trying to narrow done the error space.
It might be wise though to contact SAS Support as they can more directly engage with you and narrow done the problem far quicker.

I see.

To answer your questions :
- Can you connect to the Metadata Server? #Yes I can connect and validate on the Metadata.
- Can you start a SAS session via a client like EG? #client side I will check just now if Enterprise Guide is working.
- Can you excess any other Web-Apps? #Web portals yes they are loading fine which strange as well to me because some services are not running but web portals load.
- If not can you at least access Logon Manager? # yes, the logon manager is working fine.

I will reach out to SAS Support if this persists. Thanks a lot DavidHD.

You are welcome

I have one last question - is the Web portal deployed? You can check that by going into Web/Applications subdirectory and there should be a folder for the portal - if that is there I'm sadly out of ideas

Re: SAS servers start sequence

SASJR1 — Wed, 18 Nov 2020 08:04:14 GMT

Yes,
That I can find in that folder.

So now I'm out of ideas on how to further diagnose this - sorry

@SASJR1 - Yes I was aware of that. Support for Windows has been requested.

Hi Guys.

I managed to work around issues solved SAS Deployment Agent suppose I stopped it last but on the link from SAS the SAS Deployment Agent there it says otherwise but I managed to think outside the box remember the SAS Deployment Agent it talks on all the server and works as an agent for connecting or communicating so by stopping it first you actually disrupt the communication on my environment it worked if I stop it last on all the servers.

Thanks, a lot of guys for helping as well. Happy days for me😃😃
