Troubleshooting Enteprise manager-Tips to a newbie(2)

Have you come across a situation where you try to connect to Enterprise manager using the URL but unable to connect, giving some weird error messages.

Like java.lang.Exception: Exception in sending Request :: null or agent not found or similar ??

This is probably due to a problem with dbconsole agent.

Most of the time this is caused by the incorrect time zone selected in emd.properties

emd.properties file is found in 'Oracle_home\sysman'

Try some of there steps to solve. Might be useful

start oracle service

set oracle_sid=orcl

check timezone in emd.properties

if no valid time, set the OS time zone and add a supported entry(agentTZRegion=Asia/Calcutta)

reset agent

emctl resetTZ agent

start console

emctl status dbconsole

set agent path

set oracle_home=D:\oracle\product\10.2.0\db_1

start agent

emctl start agent

to check staus

emctl status dbcolsole

emctl status agent

to get time zone from config

emctl config getTZ
