What is EM2GO?
It is a wireless device for
Oracle database administrators to perform their task remotely.
How can I customize my
Grid Control posts by using a static ports file?
You can use the
staticports.ini file to customize your ports when you install OEM.
$ /stage/disk1/runInstaller
oracle.sysman.top.em_seed:s_staticPorts=/../staticports.ini
<DefaultPorts.htm>
Port Numbers and Ranges (Grouped by Component) <DefaultPorts.htm>
How can I 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.
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 don’t 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
What are the 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
What is Blackouts?
We use blackouts to suspend
target monitoring, schedule maintenance periods for these targets.
This will prevents unnecessary alerts from being sent while a target
is down for maintenance.
What are the differences
between Application Server Control and Grid Control?
- Grid control needs to be
installed separately but Application Server control will be installed
the same time that you install OracleAS.
- Grid has the OMS and the
Oracle Application Server control has no OMS.
- Grid has may target type
but the Oracle Server Control only has OracleAS.
- With the Oracle
Application Server Control, you can do server configuration but you
can not do this with the Grid Control.
- Both can do application
configuration.
- The application server
control is Farm/cluster aware but not Grid.
- With Grid control you can
do Group, Historical Monitoring and Alerts, Application Service Level
management, Job system, Configuration management, Mobil access via
EM2GO. But you can not do any of the above function by Application
Server Control.
How do we access to Grid
control and Application Server control?
- to access to Grid
control: http://oms-server:7777/em
- to access to Application
Server control: http://application-server:1810
