SAS 9.4 Lev2 Lev3 Installation on same machine

[anguraj1]

Hi All,

I am planning to install the SAS Servers Metadata, App server and Mid tier. Will it be possible to install the different Levels on same machine. Different Binaries for SAS Home for Dev and Test environments. like lev 4 and Lev3 .Is it advisable and will it be supported by SAS Tech support team

There is no problem running multiple instances of SAS on the same servers (Lev1, Lev2 etc) and it is fully supported by SAS. These instances run off of single version of SAS (single set of binaries).

I'm not sure what you mean by different binaries for Dev and Test. Do you mean different versions or maintenance levels of SAS? Normally you have one set of binaries, but run multiple levels. Running different maintenance levels or versions is not necessarily impossible but I don't believe it is recommended as it greatly complicates your SAS architecture.

Hi SASKiwi,

Many Thanks for the quick response. We are going to install the  SAS 9.4 M5 Version of the software in both dev and test environment. there is no change in binaries. Do we need to install the binaries again. Please confirm.

Thanks,

Anguraj S

Which os is used? On Windows you install the binaries once and just repeat the config step.

metadata and Mid tier on Windows and Linux on App server.

No problems to be expected for Meta and App, but i can't recommend to install multiple mid-tier configurations on the same machine, because of memory usage and time required to start the services.

[SimonDawson · Accepted solution]

If you do a deployment with metadata and middle tier on the same host you *must* use different directories for the configuration directories of the tiers.

eg. D:\SAS\Meta\Config\Lev2 and D:\SAS\Mid\Config\Lev2

If you combine metadata and middle tier configuration into one directory with your compute configuration out on another machines this isn't a supported configuration.

@SimonDawson: If different config directories have to be used when installing meta and mid-tier on the same machine, how are updates applied? Back in the old days (using sas 9.1) we could install all tiers on a single server (bi-server licence) and use one config directory for all tiers.

[SimonDawson]

Inside the SAS Deployment Manager you are prompted for which configuration directory you like to update. If you upgrade a deployment with a combined meta mid you need to do metadata configuration first, the do compute on the other host, then come back to first box and kick off the configuration for the mid tier.
