Symptoms

As a part of the Bug 34292052, Customer performed ExaCS discovery and below are the observations at different stages

1.Customer performed exaCS discovery using below command:

$ emcli submit_procedure -name=ExaCloudServiceDiscovery
-input_file=data:/u01/app/media/emcli_property.txt -notification="scheduled,
action required, running"

2. At the OMS side, Deployment procedure is submitted and the job is invoked.

3. At the agent side

i.  ExaCSDiscovery related GetMetricDataRequest was received:

    {discCategory=ORACLE_EXA_CLOUD_CELL, onDemand=true, pluginId=oracle.sysman.xa, __gcagent__.isOutputSensitive=true

ii . from emagent_perl.trc, csCellDiscovery.pl was invoked and exacli process is spawned. Post that there is no update/progress on exacli.

iii. Since there is no response from spawned process, Metric got timedout after 10 mins

4.At OMS side.

Since there was no target discovered, Nullpointer exception was reported in the below stack during the refresh operation in emoms.trc:
