vRO

vRealize Orchestrator (vRO) is a workflow tool designed to help IT staff simplify complex automation tasks and integrate with numerous third-party systems. It’s a key part of the vRealize Suite and VMware’s SDDC solutions. I’ve been using vRO (formerly vCO) for a number of years, but in the last few years it’s been almost constant in tandem with […]

New vRO and PowerCLI Automation Training

A lot of the projects that I work on have an element of automation to them and I’ve been asked a few times by customers if there is a training course available that will help them get started in understanding vRO and VMware’s PowerCLI cmdlets and how they can be used. Whilst there have been courses available in the past, there is a new one that reads a bit like “Doing my job 101”. It goes by the catchy title of “Data Center Automation with vRealize Orchestrator and vSphere PowerCLI“. Looking at the outline, the important stuff is there. Understanding, using and navigating the vSphere API (useful for both PowerCLI and vRO). PowerCLI basics and more advanced uses. vRO Basics and workflow creation / design. So, if you’re looking to get started with vRO or PowerCLI and use one or […]

vRA 7 / vRO 7 REST error (java.security.cert.CertificateException)

Whilst I was with a customer recently, I hit an SSL related issue whilst trying to put together a vRO workflow to orchestrate the creation of a load-balancer configuration on a Citrix Netscaler VPX. Adding the REST host(s) to vRO was accomplished without any issue, but when I came to use them my workflow failed with the following error:

As this vRO instance was running on a vRA appliance, my first port of call was starting the vRO Control Center service and make sure that the REST host certificates had indeed been imported in to vRO and were trusted. They were. Looking at the certificates themselves (as I had blindly accepted them up until that point) I noticed that they were self-signed and the cause of the error became clearer. Some software solutions generate fairly weak SSL certificates by default to […]

Changing vRA ExternalWfStubs Timeouts

I saw a question on Twitter this morning that I thought warranted a quick post: The default timeout for the various workflow stubs is 30 minutes, but they can be changed. As always, take backup copies and be careful! The six stubs that can be changed are: Expired RegisterMachine Disposing UnprovisionMachine BuildingMachine MachineProvisioned The timeout settings for External Workflow stubs are configured on the Windows server (vRA 6.x) that hosts the Manager role. The file and path required (assuming a default installation) is:

Using your favourite text editor, simply adjust the timeout value for each workflow. Most people tend to require a longer timeout for “MachineProvisioned”, often because they require longer running post-provisioning tasks to complete before handing a Virtual Machine over to the requester. Save the file and make sure that the same changes are made on the […]
