Oracle 11g: Oracle Management Agent (OMA)
To install the Oracle OMA component
The
OMA
(Oracle management Agent) connects the
OMS
to managed targets. We should install the
OMA
on every managed target host.
There are three ways to install the
OMA.
Remember always you can download the Agent from the Oracle website.
1- Using the Oracle Product CDs (Interactively). It is the same is
regular Oracle installation.
#
/stage/Disk1/runInstaller.
2- Using the batch process (Silent Installation). It is the same
as above but in silence no interaction.
#
/stage/Disk1/runInstaller responseFile ./agent.rsp silent doDiscovery=True
startAgent=TRUE
(you can find the sample response file in the $ORALCE_HOME/install
directory.
3- Using the
OMS
process (On Demand). You do not need the Oracle product CDs. Go to each
server and use its browser and type: http://oms-servername:4889/agent_download and
then select the
OMA.
Make sure that the wget utilize is in /usr/local/bin/wget. If not, then
make a link for it.
For example:
#
ln -s /usr/bin/wget /usr/local/bin/wget
You should make a new directory for the OMA before doing anything. Then
run
root.sh
Key Configuration files for the OMA
The key configuration files for the
OMA
are:
1. ./sysman/emd/targets.xml
2. ./sysman/config/emd.properties
3. ./sysman/config/emagentlogging.properties
4. ./sysman/log/. (all OMA log and trace files)
To start and stop the OMA
- to start: # $AGENT_HOME/bin/emctl
start agent
- to stop: # $AGENT_HOME/bin/emctl
stop agent
Good Luck!
