Cause

The environment parameter TZ is set to BEIST-8, which does not match the WBEIST-8/GMT setting for the agent (in /sysman/config/emd.properties):

$ grep -v "^#" /etc/environment | grep TZ
TZ=BEIST-8
$ echo $TZ
BEIST-8

$ date
Tue Nov 15 09:38:13 BEIST 2011
$ date -u
Tue Nov 15 01:38:21 GMT 2011

Solution

Set the agentTZregion value to GMT-8 in emd.properties and start agent.

1. Backup and edit /(node#_for_RAC)/sysman/config/emd.properties and set following parameter value to GMT-8:

agentTZRegion=GMT-8

2) Ensure there are no emagent or emwd processes active from agent_home:

$ps -ef | grep emagent
$ps -ef | grep agent11g
$ps -ef | grep emwd
$netstat -an| grep

3) Connect to the repository database as sysman and set the agent TZ :

SQL> select * from mgmt_targets where target_name like '%agentname%' and target_type='oreacle_emd';
SQL> exec mgmt_target.set_agent_tzrgn('','GMT-8');
SQL> commit;
SQL> select * from mgmt_targets where target_name like '%agentname%' and target_type='oreacle_emd';

4) Now start agent and take a status to confirm successful operation and upload:

$./emctl start agent
$./emctl status agent

Note:
If using agentTZregion=GMT-8 also results in failure, then start the agent with this setting in emd.properties:

$ export TZ=Etc/GMT-8
$ emctl resettz agent

and execute the steps (3) and (4).
