Hi Reka, Why is it circular ?
Probably I defined it incorrectly: What I want is the following start up sequence: After group n-st-G2-t-a-2 starts up c3 should start up, when c3 is up then c2, when c2 is up, then c1 should start up. (n-st-G2-t-a-2 -> c3 -> c2 -> c1) I am probably too tired and can’t the see the correct solution ☺ Thanks Martin From: Reka Thirunavukkarasu [mailto:[email protected]] Sent: Thursday, April 30, 2015 6:50 PM To: dev Subject: Re: Testing Stratos 4.1 - Exception when defining startup order, not sure what's wrong ? Hi Martin, We don't support any cycle in the startupOrder. It should be liner array where you can plug each string array either to a new branch in the dependency tree or to an existing node. Can you explain the startupOrder pattern of those cartridges and groups? So that i can help on how to define it in the application?
