Symptoms

 

Note:

Because the OMS instance home and OMS Oracle Home are user configurable at installation, representative values are used in this note.

The value ".../gc_inst/" is used here to represent the OMS instance home for the EM 12c installation.
The user can find the actual value of the instance home for the EM 12c Cloud Control OMS by examining the <OMS Oracle Home>/sysman/config/emInstanceMapping.properties file for the value of "EMGC_OMS1=". This value will shown as:

EMGC_OMS1=<OMS instance home>/em/EMGC_OMS1/emgc.properties

For instance, if this line is found in emInstanceMapping.properties:

EMGC_OMS1=/u01/app/EM12c/gc_inst/em/EMGC_OMS1/emgc.properties

then the value for OMS instance home is /u01/app/EM12c/gc_inst.

The value used to represent the OMS Oracle Home is .../Middleware/oms/.
