My vSphere lab is split into two halves - a low power management cluster, powered by 3 Intel NUCs, and a more hefty workload cluster powered by a Dell C6100 chassis with 3 nodes. The workload servers are noisy and power hungry so they tend to be powered off when I am not using them, and since they live in my garage, I power them on and off remotely.
Back in January 2015 I wrote an article on how to modify the Java heap settings for the vCenter Orchestrator client when working with very large workflows. Since vRealize Orchestrator 7.x has been released, we no longer have an installable client, just a Java WebStart file (.jnlp) that you run, or a package that you can download - but nothing that installs. Note that none of this is official or supported by VMware as far as I know - it’s the results of my experimentation which has shown some performance improvement by increasing the configured memory pool.
Big thanks to Jose Luis Gomez for this solution, his response to my tweet was spot on and invaluable! I’ve been trying to configure vCloud Air as a vCloud Director host in vRealize Orchestrator in order to create some custom resource actions for Day 2 operations in vRealize Automation. What I found was that there’s *very* little information out there on how to do this, and I ended up writing my own custom resource mapping for the virtual machines to VCAC:VirtualMachine objects - at least that way I could add my resource action.
If you use the in-built vRealize Orchestrator instance shipped with the vRealize Automation appliance then you might run into this issue when working with the REST client: Connection pool shut down (Workflow:Get-IdentityToken / Scripting (item3)#14) The vRA appliance version I have (6.2 - note to self, need to update lab!) includes the plugin version 1.0.4 for REST. According to the release notes, this was fixed in 1.0.5 - typical!
I tested vSphere 6 quite intensively when it was in beta, but I didn’t ever upgrade my lab – basically because I need a stable environment to work on and I wasn’t sure that I could maintain that with the beta. Now 6 has been GA a while and I have a little bit of time, I have begun the lab upgrade process. You can see a bit more about my lab hardware over on my lab page.
Recently, I’ve had a bit of a SOAP baptism of fire - the project I am working on makes hundreds of SOAP calls to multiple SOAP APIs on multiple hosts. During this time I’ve encountered some common and rare problems and troubleshooting them seems to be a bit of a black art, if the number of results in Google is any measure. To demonstrate some of these troubleshooting methods I will use a global weather SOAP service, http://www.
When you are using a VMware orchestration platform with an official VMware plugin to manage a VMware product, you don’t really expect to have to fix the out-of-the-box workflows. However, during some testing of some workflows with a client the other day we ran into a couple of issues with the vCloud Director plugin workflows. Software versions used vCloud Director 5.5.1 (appliance for development) and 5.5.2 (production deployment) vRealize Orchestrator Appliance 5.
[Update Dec 2016: An updated article for vRO 7.x is available here] I’m developing some very large, very complicated workflows for vRealize Orchestrator (vRO/vCO), and as it’s a Java based application it will probably come as no surprise to many that the performance of the client drops off sharply as the client’s RAM usage creeps up. When working on some of the larger workflows, or after long sessions and heavy clipboard use, the client would become (even more) sluggish and in some cases would freeze entirely.
It’s a fairly common requirement when creating a new user to assign a randomly generated password, so during a recent engagement I wrote a little password generator to do that. I wanted to be able to chose whether special characters were used, and the length of the password - typically if the password doesn’t used special characters I would increase the length significantly! Characters should be randomly picked from:
