Enterprise Manager target discovery cannot detect listener started via an ifile (Doc ID 1546664.1)

Last updated on AUGUST 22, 2014

Applies to:

Enterprise Manager for Oracle Database - Version 10.2.0.5 to 12.1.0.3.0 [Release 10.2 to 12.1]
Information in this document applies to any platform.

Symptoms

It is not possible for Enterprise Manager Grid Control 10g or  Grid Control 11g or Cloud Control 12.1.0.1  to discover a listener which has been started using the ifile parameter .  For example:-

1) create a listener which uses an ifile
contents of listener.ora are:-

IFILE=c:\Testhome\network\admin\listener_test.ora

contents of listener_test.ora are:-

SID_LIST_LISTENERtest =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = test)
      (ORACLE_HOME = c:\Testhome\network\admin)
      (SID_NAME = test)
    )
  )

LISTENERtest =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = machine1)(PORT = 15888))
  )

LOG_DIRECTORY_LISTENERtest = c:\Testhome\network\admin

2) Attempt to discover the database and listener in Grid Control
3) The listener will not be detected.

Additionally, starting a 12c agent may result in server memory utilization reaching 100% and server crashing.
