Refreshing the Oracle Public Cloud Machine Target

You should consider refreshing the system whenever you upgrade the OPCM Rack, for example, from a quarter to half. You should also consider refreshing when you discover Oracle VM Manager or ZFS targets after the OPCM system is discovered. To refresh the OPCM target, follow these steps:

1. From the Targets menu, select Oracle Public Cloud Machine.

2. From the list of targets, click the Oracle Public Cloud Machine target you want to view.

3. From the Oracle Public Cloud Machine menu, choose Refresh System.

   Cloud Control displays a Discovery Inputs page with the fields pre-populated.

   Click Next to start the discovery action or Cancel to cancel.

4. On the Review page, click Submit to start the refresh action or Cancel to cancel. Once Submit is clicked, a progress dialogue appears that shows a confirmation:

   Once the operation is complete, the dialog will close and Cloud Control will update to show all OPCM targets.

Displaying and Using the OPCM Dashboard

Use the Dashboard to view status information about software and hardware targets in the OPCM:

• Using the Software Tab

• Using the Hardware Tab

• Using the Resources Utilization Tab

• Using the Control Infrastructure Tab

To display and use the Dashboard, follow these steps:

1. From the Targets menu, select Oracle Public Cloud Machine.

2. From the list of targets, click the OPCM target you want to view. The dashboard displays the details.

3. You can return to this page at any time by choosing Home from the Oracle Public Cloud Machine target menu.

4. You can display General Information about the target by choosing Target Information from the Oracle Public Cloud Machine target menu.

Using the Software Tab

Use the Software tab on the OPCM dashboard to display status information including alerts and key performance metrics of the following targets:

• Application Deployments - see Viewing Application Deployments in the OPCM Target

• WebLogic Domains - see Viewing WebLogic Domains Hosted on the OPCM Target 

• Coherence Clusters - see Viewing Coherence Cluster Targets

• Hosts - see Viewing Host Targets on the OPCM Rack

The Software tab displays an Incident section in the table for each element, such as Application Deployments or WebLogic Domains, that shows alerts on which you can drill down for more information.

The Software tab displays large numbers of software targets that are members of the OPCM system. You can use the inter-region filtering option to conduct a page level search. For example, if the search is performed for an Oracle WebLogic Domain, the Applications region is also filtered to show all the applications deployed on the WebLogic servers that are members of the searched WebLogic domain. Similarly the Host region is filtered to show hosts that are hosting the WebLogic servers that are part of the searched WebLogic domain.

Viewing Application Deployments in the OPCM Target

Use the Application Deployments page to view details about the applications hosted on the hosts running on the OPCM target.

To view application deployments, follow these steps:

3. You can drill down to specific applications, targets, domains, or dependencies by clicking on its related value in each row.

4. You can filter the list of applications by choosing a value from the Status drop-down. You can select from Up, Down, Unknown, Blackout, and All.

5. You can change the column appearance of the table by clicking View and choosing which Columns to display, expanding or collapsing rows, or scrolling to the first or last row. You can also reorder columns.

6. You can use the Topology tab to display a pictorial view of the Application Deployments in various relational configurations.

Viewing WebLogic Domains Hosted on the OPCM Target

The Hardware tab displays the number of hardware units in each category along with their status in the Overview section. It also shows the Incidents associated with the hardware. The Rack Hardware schematic shows the position of each hardware component on the rack. You can use the Incidents section to monitor hardware issues that arise and then drill down to the Incident Manager page by clicking the Incident Summary for more details about the incident.

You can use the Hardware tab to view information such as Temperature (by turning on the Temperature option at the top of the Rack Schematic) and Status, as well as a Hardware Schematic depicting the current state of the hardware.

Using the Resources Utilization Tab

On the Resources Utilization tab, each box represents a compute node:

• The size of the box represents the average CPU utilization of a compute node over the last 24 hours.

• The color of the box indicates the average memory utilization of compute node over the last 24 hours.

• Large boxes indicate compute nodes with high average CPU utilization.

Creating Reports in Enterprise Manager

You can create the following reports in Enterprise Manager:

• Oracle BI Instance Performance -- This report covers all BI instances running on the selected OPCM rack. First a list of all WebLogic domains associated with the selected rack is read, then all oracle_ias_farm targets associated with those WebLogic domains are determined and then the list of all BI instances associated with those oracle_ias_farm targets are identified.

• Oracle Internet Directory Performance -- This report covers all OID servers running on the selected OPCM rack. First a list of all WebLogic domains associated with the selected OPCM rack is read, then all oracle_ias_farm targets associated with those WebLogic domains are determined and then the list of all OID servers associated with those oracle_ias_farm targets are identified.

• Oracle Service Bus Performance -- This report covers all OSB servers running on the selected OPCM rack. First a list of all WebLogic domains associated with the selected OPCM rack is read and then all OSB server targets associated with those WebLogic domains through ’r;farm' association are identified. This report has two sections under each OSB server – Top Business Services and Top Proxy Services. These sections show the top five business services and the top five proxy services respectively. The top five services are determined based on the decreasing order of max value of throughput (for example, messages per minute) metric for each service during the selected period.

• SOA Infrastructure Performance -- This report covers all SOA Infrastructure targets running on the selected OPCM rack. First a list of all WebLogic domains associated with the selected OPCM rack is read and then all SOA Infrastructure targets associated with those WebLogic domains through ’r;farm' association are identified. The SOA Infra Engine related charts cover only the following four engine types - bpel, bpmn, mediator and workflow.

• Oracle WebLogic Server Performance -- This report covers all WebLogic servers running on the selected OPCM rack. The list of all WebLogic domains associated with the selected OPCM rack is read. The report is divided into sections based on different WebLogic domains. For each domain, the top five servers are shown in the charts for each metric. The top five servers for each metric are determined by decreasing order of max value for the metric for each server in the selected period.

• Compliance Summary -- This report give a brief summary about the compliance standards evaluated for the middleware targets like WebLogic server, domains, clusters, host, and so on, running on the OPCM system. The report shows the list of top ten least compliant WebLogic domains and host and Compliance Standard Summary.

• Compliance Details -- This report give details on about the compliance standards evaluated for middleware targets like WebLogic domains, servers, clusters, hosts, and so on, running on the OPCM system. The reports show the top ten least compliant WebLogic domains and host and a detailed list on compliance rules violated for the middleware targets.

The Reports menu item is visible in the Oracle Public Cloud Machine target menu if BIP is configured with Enterprise Manager. If BIP is not configured, the menu item does not appear.

To create reports, follow these steps:
