4.2 OMS configuration management

View version:
$ <OMS_HOME>/emctl getversion oms

View status:
$ <OMS_HOME>/emctl status oms

To view oms details:
$ <OMS_HOME>/emctl status oms –details

Specify password to view details:
$ <OMS_HOME>/emctl status oms -details -sysman_pwd Oracle123

View properties:
$ <OMS_HOME>/emctl list properties

Start stop command:
$ <OMS_HOME>/emctl stop oms
$ <OMS_HOME>/emctl start oms
Modify memory (restart takes effect):

1. Command modification:

$ <OMS_HOME>/emctl get property -name OMS_HEAP_MAX -sysman_pwd Oracle11g

$ <OMS_HOME>/emctl set property -name OMS_HEAP_MAX -value 2048M -sysman_pwd Oracle11g

$ <OMS_HOME>/emctl get property -name OMS_HEAP_MIN -sysman_pwd Oracle11g

$ <OMS_HOME>/emctl set property -name OMS_HEAP_MIN -value 512M -sysman_pwd Oracle11g

2. Modify the attribute profile directly:

4.3 agent configuration management

View version:

$< agent > / emctl GetVersion agent (view version)

Start stop and check status:

$ <AGENT>/emctl status agent

$ <AGENT>/emctl stop agent

$ <AGENT>/emctl start agent

Test whether the agent is connected to OMS:

$ <AGENT>/emctl pingOMS

Upload agent to OMS of server

$ <AGENT>/emctl upload agent

5. Add host

Configure hosts resolution (source and target)

vim /etc/hosts
network.ip  hostname

Settings -- add target -- add target manually

6. Add database
