The following sections describe how to discover the Exalytics In-Memory System and Machine and other supported targets:
Once you have discovered the Exalytics System target in Enterprise Manager Cloud Control, complete the instructions outlined in Post-Discovery Configuration and Verification.
Note:
The Oracle TimesTen In-Memory Database is part of most Exalytics systems. For more information on complete installation, discovery, and configuration details, see the Oracle® Enterprise Manager System Monitoring Plug-in for Oracle TimesTen In-Memory Database User's Guide.
Complete the following prerequisites before beginning the discovery process:
em-context.info
FileBefore the Exalytics host can be discovered by Enterprise Manager Cloud Control, there are some configuration steps that must first be completed and the em-context.info
file, which provides Enterprise Manager with the system identifier of your Exalytics System, must be created. To create the em-context.info
file, perform the following steps:
Before proceeding to discovery, verify that the following prerequisites are met for your virtualized Exalytics Machine:
A directory should be NFS exported before it can be mounted on other host. Follow the steps below as the root
user:
For a virtualized Exalytics machine, follow these instructions from the Oracle® Enterprise Manager Cloud Administration Guide for:
Generally, Oracle Fusion Middleware domains do not remain static. Instead, membership in the domain changes regularly, for example: New Java EE applications are deployed, WebLogic Server instances are created or removed, clusters are added, and so on.
By default, Enterprise Manger Cloud Control is not automatically aware of changes made to the domains, which have been configured as managed targets. However the application does provide the ability to discover and uptake new or modified domain members.
For details about discovering Fusion Middleware domains (including new, modified, and multiple domains), see Discovering Middleware Targets in the Oracle® Enterprise Manager Cloud Control Getting Started with Oracle Fusion Middleware Management guide.
You can enable a pre-defined Cloud Control job named WebLogic Domain Refresh to automatically discover new domain members and add them as managed targets.
From the Targets menu, select Middleware.
Click the WebLogic Domain you want to enable the job in the Middleware home page.
In the General region of the page, click the timestamp link next to the WebLogic Domain Refreshed property. The Refresh WebLogic Domain dialog opens.
Check the Enable Automatic Refresh box in the Refresh WebLogic Domain dialog, then click OK.
Once enabled, the job will check for new domain members once every 24 hours by default. To change the job settings, including the frequency at which it is run:
Cisco monitoring in 13c target uses the System Infrastructure Plug-in, where the Agent requires SSH access to the Cisco switch.
12c Target Type: Can monitor Cisco switch via SNMP. SSH access is not mandatory.
13c Target Type: SSH access information is required when adding this target type.
You will need to have your Cisco IOS and SNMP credentials available.
An Exalytics system consists of multiple Exalytics machines that are clustered. For monitoring, there are two targets in Enterprise Manager:
The Exalytics Machine target that represents one physical machine.
The Exalytics System target which represents multiple machines that are clustered and need to be monitored as a whole.
Regardless of the target type to be monitored, you will always select an Exalytics System for discovery - even if there is only one Exalytics Machine.
To discover an Exalytics System target:
