After you perform an Oracle E-Business Suite R12 installation (12.1.1) using Rapid Install, the concurrent managers may not get started. The Node can be shown as AP653APP.us.oracle.com which seems to be an internal Oracle Corporation's server name. Furthermore, the status message could be ""System Hold, Fix Manager before resetting counters".
There is no apparent reason why the 12.1.1 installation refers to a non-existent node name AP653APP.us.oracle.com. This does not go away even after upgrading to 12.1.3 maintenance pack. But you can use the solution described in http://www.appsdba.info/docs/others/Troubleshoot_cm.pdf. This invalid node name can cause even the database listener startup to fail with the below error messages because of this invalid node name in sqlnet.ora's tcp.invited_nodes parameter.
TNS-12560: TNS:protocol adapter error
TNS-00584: Valid node checking configuration error
tcp.invited_nodes=(AP653APP.us.oracle.com, dbserver.yourcompany.com, appserver.yourcompany.com)
