Symptoms

When attempting to start Discoverer an error similar to the following is returned:

opmnctl: starting opmn and all managed processes...
================================================================================
opmn id=machine.oracle.com:6201
6 of 7 processes started.

ias-instance id=BI.machine.oracle.com
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
--------------------------------------------------------------------------------
ias-component/process-type/process-set:
Discoverer/PreferenceServer/PreferenceServer

Error
--> Process (pid=10755)
failed to start a managed process after the maximum retry limit
Log:
/home/ias/OraHome_BI/opmn/logs/Discoverer~PreferenceServer~1



Another symptom that can occur is the preferences start up fine; however, E-Business Suite procosses attach to the same port.  When a user updates their preferences in Discoverer Plus/Viewer and/or global preferences are applied with a the applypreferences script, the preference registry (.reg_key.dc) file is not updated.
