The automatically EBS services created by the discovery like : Oracle Applications Infrastructure Service , Application system, applications node system are not using the OS timezone as all otheredtabase,listner, forms, workflow .... but instead using the DBTIMEZONE of the target DB and even some are using DBTIMEZONE of the OEM repository !!!!!
It's really disturbing for our users who are using OEM EBS dashboard to check environment availability. As i dont intend to modify my DBTIMEZONE on all my database (i have to shutdown and restart all the DB), how can i change the setup in OEM for these services to use the common timezone (means $TZ) ?
