AWI and Tomcat

[Tina Hart]

Good Morning,
We're about to update our Development environment to 12.3.1, and I had a question regarding Tomcat and AWI.  In our current build, we very very rarely have used ECC so we never had the site hosted via an official Tomcat server.
I've discussed with a few others in our company that have other Automic installations, and one is using a separate webserver only for AWI and the other are just using the Tomcat service in Service Manager.
Just wondering what others have done with the newer versions of the AWI; separate server with Tomcat that only hosts AWI?  same server, but also installing an instance of Tomcat webserver?  only using Service Manager to manage Tomcat?  Our current enviornment are 1 server for development that has the Automation Engine installed and 1 in production that is the same.

Thanks!
Tina

We opted to go with separate servers for the AWI.  Obviously it increases your server footprint.  We have 2 AE's and 2 Web servers per system - simply so that during patching, etc. we don't have to bring the system down.  Working fine for us so far.

We are a small shop, and combined everything onto one windows server, including its SQLServer database.   Our attitude is that if we run into performance issues, we can afford to throw hardware at it.  Initially tomcat was running out of RAM, so we had to boost that, and now it seems to be fine.   

We have only one server for development which is currently hosting 18 clients.   The smaller server footprint has benefits, but it is certainly at the cost of AE server performance.  We just happen to be too small for it to make a noticeable business impact.

We did split up the storage.  The C-drive is reserved for the OS, we put the database on the D-drive, all application code is on the E-drive, and we are storing our UC4 archives on the F-drive.

Hi Tina,

Our Preproduction env is on 12.3.1 and we run approx 1.2M executions every day, so it's quite a busy system.
We have four AE servers and they are quite powerful, so I decided to install the AWI/Tomcat on the same servers.

Our Production env is still on 11.2.10 and we plan to upgrade to 12.3.2 within a month or so..

Hi

We have PROD and UAT
each system runs on 2 linux servers with an oracle RAC, we have on both linux servers an AWI instance but for Admin team only (tests etc.)

For our users we have a seperate AWI instance on 2 servers, but this will be changed this or next year to other hardware and config (2..4 servers, tomcat, webserver, ...)

cheers, Wolfgang

Thanks everyone for the responses!!!  

After reviewing how we use the tool, and how users are using the tool, we decided to add a separate server for AWI at this point and built to the specs in support.
