Investigation

OMA Start Up Fails

The start-up of the OMA fails with the following message:

Oracle Enterprise Manager Cloud Control 12c Release 4 Copyright (c) 1996, 2014 Oracle Corporation. All rights reserved. Starting agent .............failed. Consult emctl.log and emagent.nohup in: /opt/app/oracle/agent12c/agent_inst/sysman/log

Examine Logs

The log, /opt/app/oracle/agent12c/agent_inst/sysman/log/emagent.nohup, shows the following message:

OMS decided to shutdown the agent because of the following reason sent from OMS: AGENT_TZ_MISMATCH

Check OMA Time Zone

I used the following command to check the time-zone used by the agent (OMA):

/opt/app/oracle/agent12c/agent_inst/bin/emctl config agent getTZ

The result was:

Oracle Enterprise Manager Cloud Control 12c Release 4 Copyright (c) 1996, 2014 Oracle Corporation. All rights reserved. Australia/ACT

Correct Time Zone

Check for Supported Time Zones

The supported time zones are in /opt/app/oracle/agent12c/core/12.1.0.4.0/sysman/admin/supportedtzs.lst. In that file, I found the following time zone:

Australia/Sydney

Update OMA Configuration

The OMA configuration in /opt/app/oracle/agent12c/agent_inst/sysman/config/emd.properties was updated with:

agentTZRegion=Australia/Sydney

Configure OMA with New Time Zone

I used the following commands to update the OMA with the following commands:

export TZ=Australia/Sydney /opt/app/oracle/agent12c/agent_inst/bin/emctl resetTZ agent

The result was:

Oracle Enterprise Manager Cloud Control 12c Release 4 Copyright (c) 1996, 2014 Oracle Corporation. All rights reserved. Updating /opt/app/oracle/agent12c/agent_inst/sysman/config/emd.properties... Successfully updated /opt/app/oracle/agent12c/agent_inst/sysman/config/emd.properties. Login as the em repository user and run the script: exec mgmt_target.set_agent_tzrgn('gordon.yaocm.id.au:3872','Australia/Sydney') and commit the changes This can be done for example by logging into sqlplus and doing SQL> exec mgmt_target.set_agent_tzrgn('gordon.yaocm.id.au:3872','Australia/Sydney') SQL> commit

Update OMR

On REPOS, the following SQL*Plus commands were run:

exec mgmt_target.set_agent_tzrgn('gordon.yaocm.id.au:3872','Australia/Sydney') commit;

Continue with OMA Installation

Start OMA

Started OMA with the following command:

/opt/app/oracle/agent12c/agent_inst/bin/emctl start agent

The result was:

Oracle Enterprise Manager Cloud Control 12c Release 4 Copyright (c) 1996, 2014 Oracle Corporation. All rights reserved. Starting agent ........ started.

Add Internal Targets to OMA

Added internal targets to the OMA with the following command:

/opt/app/oracle/agent12c/agent_inst/bin/emctl config agent addinternaltargets

The result was:

Oracle Enterprise Manager Cloud Control 12c Release 4 Copyright (c) 1996, 2014 Oracle Corporation. All rights reserved.

Run Root Script

Ran the OMA root script with the following command:

sudo /opt/app/oracle/agent12c/core/12.1.0.4.0/root.sh

The result was:
