Increasing the Java Heap size for vRealize Orchestrator Client (7.x)

vRealize OrchestratorBack 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. Use it at your own risk! (more…)

Performance tweak – increasing Max Heap Size for the vRealize Orchestrator (vRO/vCO) Client

vRealize Orchestrator[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. This is particularly annoying because the vRO client has a habit of forcing itself on top of other applications – for instance Task Manager.

Exhibit 1 – a large workflow!
