I recently deployed a soa composite application on em (Enterprise Manager) but it took 1 hour to deploy (it got deployed successfully after an hour) which resulted in admin and other server to go in critical state. I tried the same in lower environment but the deployment took less then a minute Few points: I double cross checked the configuration plan that was used with the jar, its correct. The jar was tested in lower envmt before deploying to higher envmt.
What can be the reasons for long deployment.
