VRA 6.2 DEPLOYMENT
Enter a name for the monitor, and leave the other parameters the same. Select the “Special Parameters” tab and configure the send string to the URL to monitor - e.g for the PSC SSO it’s going to be: GET /websso/HealthStatus For the receive string, enter the expected response (“GREEN”). Click Create. Assigning a NetScaler Monitor to a Service Assign the monitor to the PSC Services (or Service Groups) configured for PSC by opening the Configuration > Traffic Management > Load Balancing > Services page and selecting the PSC service for HTTPS/443 and clicking Edit.
Deploying fully distributed vRealize Automation IaaS components – Part 2: Database, Web and Manager services
Now that the prerequisites for the IaaS layer have been completed, it’s time to move on to the actual installation of the IaaS components, starting with the database. We then move onto the first Web server, which also imports the ModelManagerData configuration to the database, populating the database with all of the info the IaaS layer needs out of the box. We then install the second Web server before moving on to the active Manager server.
One of the trickiest parts of deploying vRealize Automation is the IaaS layer - people sometimes look at me like I’m a crazy person when I say that, normally because they’ve deployed a PoC or small deployment with just a single IaaS server. Add in 5 more servers, some load balancers, certificates, a distributed setup and MSDTC to the mix and you have a huge potential for pain! If you’ve followed my previous posts, you’ll see know that I’ve got a HA Platform Services Controller configured, and a HA vRealize Appliance cluster configured with Postgres replication - all good so far.
The recommendations for the vRealize Appliance have changed with 6.2, the published reference architecture now does not recommend using an external Postgres database (either vPostgres appliance, a 3rd party Postgres deployment or using a third vRealize Appliance as a stand-alone database installation). Instead the recommended layout is shown in the diagram below. One instance of postgres on the primary node becomes an active instance, replicating to the second node which is passive.

SSO is a fundamental requirement when deploying vCAC, whether for a distributed or simple installation. This walk through goes through the deployment and configuration of the vCAC Identity Appliance, which provides a stand alone SSO instance for vCAC. Some of the posts in this series are completed with vCAC 6.0.1, others will be with 6.1. Where there are differences I will aim to point them out!
