Add PowerShell Host fails in vRO 7.x

While making an attempt to add PowerShell host in vRO 7.x fails with an error

Initial Error: ‘Add a PowerShell host/item8’, state: ‘failed’, business state: ‘null’, exception: ‘Clients credentials have been revoked (18) (Dynamic Script Module name : addPowerShellHost#12)’
workflow: ‘Add a PowerShell host’ (EF8180808080808080808080808080803D80808001270557368849c62c352aa82)
|  ‘attribute’: name=errorCode type=string value=Clients credentials have been revoked (18) (Dynamic Script Module name : addPowerShellHost#12)

investigation into this came up with some very basic issues.

vRO was configured with External MS SQL Db which was being authorized by particular AD account credentials, and that account itself was locked out. This might have happened due to multiple wrong password logon attempts and that created communication between vRO and DB server to fail.

this was tracked by going in vRO configurator page where it was throwing error:

Error! Error occured while retrieving nodes configuration. org.springframework.transaction.CannotCreateTransactionException: Could not open JPA EntityManager for transaction; nested exception is javax.persistence.PersistenceException: org.hibernate.exception.GenericJDBCException: Could not open connection
Error in both the vRO node is: couldn’t connect to database server.

but when checked with DB admin, they said DB is healthy enough and vRO node was able to reach DB server via ping as well. But when tried to test connection with service account, it was found to be locked. Unlocking same resolve everything, and was able to add powershell host also successfully.


Simplified exam booking process

on 05/03/2016, PeasonVue and VMware announced a new process of Booking or Managing your VMware Certification exams.

As part of this, now you don’t have to request Authorization for Exam and then separately launch PearsonVue portal to book the exam. There’s no need to even maintain two accounts across these two websites.

All you got to do is, GO in your account. And then simply click on ‘Getting Started’ Tab. That’s where under Exam Authorization section, you will find a link to launch ‘Pearson Vue: Manage Exam’, which is single sign-on with your current mylearn portal account. See following screenshot
