5.1 Creating Roles to Manage the Plug-in

To manage the plug-in, you need to create roles and administrators, and then assign roles to administrators. This restricts the privileges that each user has, for example in deleting the plug-in or accessing reports.

Note:

For security reasons, Oracle recommends that the SYSMAN account be used only as a template to create other accounts, and not used directly.

To create roles to provide management rights to users:

  1. Log in to the Enterprise Manager Cloud Control as the super administrator user.

  2. Click Setup, then Security.

  3. Select Roles.

    On the Security page, a list of predefined roles is provided. These roles can serve as basis to define custom roles to suite specific site level requirements.

    Note:

    The predefined roles provided cannot be edited or deleted.
  4. Select a role that closely matches the role you wish to create. Click Create Like.

  5. On the Properties page, enter a name for the role you wish to create. You can optionally add a description.

    Click Next.

  6. On the Roles page, select the roles from the list of Available Roles. Click Move to add the role to Selected Roles.

    Click Next.

  7. On the Target Privileges page, select the privilege you want to grant to the new role.

    Click Next.

  8. On the Resource Privileges page, you can edit specific privileges to be explicitly granted. Click the Manage Privilege Grant edit icon to make the changes.

    Click Next.

  9. On the Administrators page, select the administrators from the list of Available Administrators that you want to grant the new role to. Click Move to add the administrator to Selected Administrators.

    Click Next.

  10. On the Review page, a complete summary of the new role you have created is displayed. Click Back to go to previous screens to make changes. Click Finish to complete the role creation.

When the newly created administrator logs in, unlike SYSMAN, the administrator is restricted by the privileges set.

5.2 Viewing Exadata Database Machine Topology

Database Machine management simplifies monitoring and managing tasks by integrating all hardware and software components into one entity. You do not need to monitor each target individually, but instead you can view the whole Exadata Database Machine as a single target. You can view all critical issues in the system, monitor performance, and drill down to individual targets from the Database Machine target home page.

The following topology topics are presented in this section:

Use the Topology page of Database Machine to view the topology of the system by Cluster or by Database. Clusters are a complete software system starting with a RAC database, the underlying ASM, and CRS. Clusters define one logical entity that is interconnected. The Database Machine could include several clusters, one cluster, or could just be a number of individual databases. While cabinets define the hardware topology of the Database Machine, clusters define the logical or system topology of the Database Machine.

You can view the Topology by Cluster or Database. Click an element in the Topology and view alert data associated with the element.

You can monitor all components of the Database Machine. Database Machine monitors all subcomponent targets, whether hardware or software. This includes the database, ASM, CRS, hosts, Exadata and the InfiniBand network.

To view the topology of an existing Database Machine target:

  1. From the Targets menu, select Exadata.

    Enterprise Manager displays the Oracle Exadata Database Machines page showing all the available Database Machine targets. From this page, you can add hardware components (such as Oracle Exadata Storage Servers, InfiniBand switches, Ethernet Switches, KVM switches, PDU, and compute node ILOM) in the Oracle Database Machine as managed targets.

  2. From the Oracle Exadata Database Machines page, select the Oracle Database Machine target whose topology you want to view.

  3. From the Oracle Database Machine Home page, click Target, then select Members Topology from the drop-down menu.

    Enterprise Manager Cloud Control displays the Configuration Topology page.

5.2.1 Drilling Down to Individual Targets

You can drill down immediately to a subcomponent target of the Database Machine (such as RAC, a database instance, or an Exadata cell).

To drill down to individual targets:

  1. From the Targets menu, select Exadata.

    Enterprise Manager displays the Oracle Exadata Database Machines page showing all the available Database Machine targets.

  2. From the Oracle Exadata Database Machines page, select the Oracle Database Machine target whose components you want to view.

5.3 Exadata Storage Server Management

This section provides introductory instructions for managing Exadata Storage Servers. The following topics are presented:

5.3.1 About Exadata Storage Server

An Exadata Storage Server is a network-accessible storage array with Exadata software installed on it. Use the Exadata Home page to manage and monitor the Oracle Exadata Storage Server (also known as Exadata cell) by managing it as an Enterprise Manager Cloud Control target. You can discover and consolidate management, monitoring and administration of a single or a group of Oracle Exadata Storage Servers in a datacenter using Enterprise Manager.

Exadata Storage Servers can be discovered automatically or manually. Once discovered, you can add them as Enterprise Manager targets. The individual Exadata Storage Server is monitored and managed as an Enterprise Manager target and provides the exception, configuration and performance information.

Grouping of Exadata Storage Servers is used for easy management and monitoring of the set of Storage Servers. You can group them both manually and automatically. The grouping function provides an aggregation of exceptions, configuration and performance information of the group of cells.

You can view performance analysis by linking Exadata performance both at a cell level and group level to ASM and database performance. You can drill down to Exadata configuration and performance issues from both the database and ASM targets.

Storage Grid (for example, multiple database/ASM instances sharing the same Exadata Storage Server) is supported to the same extent as dedicated storage.

5.3.2 Using Exadata As a Cloud Control Target

Use Oracle Exadata to manage and monitor the Oracle Exadata Storage Server (also known as Exadata cell) by managing the Exadata cells as Enterprise Manager Cloud Control targets. You can discover and consolidate management, monitoring and administration of a single or a group of Oracle Exadata Storage Servers in a datacenter using Enterprise Manager.

Exadata cells can be discovered automatically or manually. Once discovered, you can add the Exadata cells as Enterprise Manager targets.

The individual Exadata cell is monitored and managed as an Enterprise Manager target and provides the exception, configuration and performance information.

Grouping of Exadata cells is used for easy management and monitoring of the set of Exadata cells. You can group Exadata cells both manually and automatically. The grouping function provides an aggregation of exceptions, configuration and performance information of the group of cells.

You can view performance analysis by linking Exadata performance both at a cell level and group level to ASM and database performance. You can drill down to Exadata configuration and performance issues from both the database and ASM targets.

5.3.3 Viewing an Exadata Storage Server Configuration

You can view the configuration of an Oracle Exadata Storage Server target by following the steps below:

  1. Navigate to the Exadata Storage Server home page by choosing the Exadata target for which you want to view the IORM Performance page from the All Targets page.

    Enterprise Manager displays the Exadata Storage Server Home page for the target you selected.

  2. From the Target menu, choose Configuration and then Topology.

    Enterprise Manager displays the Configuration Topology page for the selected Exadata Storage Server. The topology page provides a visual layout of a the target's relationships with other targets. From this page you can:

    • Do a target search filtered by target status/events/target type)

    • Select from a set of relationships to represent in the graph

    • Select annotations to display in the graph, such as alerts and link labels

Once you have accessed the IORM page, you can make the following modifications:

The IORM Monitoring section of the page provides a view of the performance statistics of Disk IO (Wait, IOPS, MBPS, Utilization, Latency, and Objective charts). These statistics help to identify which databases and consumer groups are using the available resources. They also help to adjust the IORM configuration (using IORM Settings section on the same page) as needed.

For further details on managing I/O resources, refer to the Managing I/O Resources chapter in the Oracle® Exadata Storage Server Software User's Guide.

5.3.5.1 Modify the Disk I/O Objective

To update the I/O Resource Manager (IORM) settings (for Exadata Storage Server software release 11.2.3.2.0 or later):

  1. Navigate to the IORM Performance page as described above. Figure 5-8 shows the I/O Resource Manager (IORM) Settings pane.

    Figure 5-8 I/O Resource Manager (IORM) Settings

    Surrounding text describes Figure 5-8 .

    Note:

    You can also update a single cell. Expand the Exadata Grid group to view all cells associated with the group. Click the cell you want to update.

    The steps to update the IORM settings is the same for a single cell or group of cells.

  2. In the Disk I/O Objective drop-down menu, select an objective from the list (Auto is the default):

    • Low Latency - Use this setting for critical OLTP workloads that require extremely good disk latency. This setting provides the lowest possible latency by significantly limiting disk utilization.

    • Balanced - Use this setting for critical OLTP and DSS workloads. This setting balances low disk latency and high throughput. This setting limits disk utilization of large I/Os to a lesser extent than Low Latency to achieve a balance between good latency and good throughput.

    • High Throughput - Use this setting for critical DSS workloads that require high throughput.

    • Auto - Use this setting to have IORM determine the optimization objective. IORM continuously and dynamically determines the optimization objective, based on the workloads observed, and resource plans enabled.

    • Basic - Use this setting to disable I/O prioritization and limit the maximum small I/O latency.

    Click Update. The Exadata Cell Administration Wizard will appear prompting you for the information necessary to complete the Disk I/O Objective configuration:

    1. On the Command page, the Cell Control Command-Line Interface (CellCLI) value should be:

      # alter iormplan objective = 'auto'
      

      Click Next.

    2. On the Admin Credentials page, enter the username and password for the selected cells.

      Click Next.

    3. On the Schedule page, enter a job name (required) and job description (optional). Select an option to start Immediately or Later. If you select the Later option, enter the time you want the job to run.

      Click Next.

    4. On the Review page, verify the settings are correct. If there are no changes, click Submit Command.

    5. Once the job is successfully submitted, the Job Status page will display.

      Click Return to return to the I/O Resource Manager (IORM) Settings pane.

  3. Click Get Latest to refresh the page, which will include your Disk I/O Objective selection.

  4. Confirm the IORM objective settings. From the command line, run the following command:

    # dcli -g cell_group cellcli -e "list iormplan attributes objective"
    

    Output should show a value of auto:

    cell01: auto
    cell02: auto
    cell03: auto
    .
    .
    .
    cell14: auto
    

5.3.5.2 The Inter-Database Plan

An inter-database plan specifies how resources are allocated by percentage or share among multiple databases for each cell. The directives in an inter-database plan specify allocations to databases, rather than consumer groups. The inter-database plan is configured and enabled with the CellCLI utility at each cell.

The inter-database plan is similar to a database resource plan, in that each directive consists of an allocation amount and a level from 1 to 8. For a given plan, the total allocations at any level must be less than or equal to 100 percent. An inter-database plan differs from a database resource plan in that it cannot contain subplans and only contains I/O resource directives. Only one inter-database plan can be active on a cell at any given time.

You can view the current configured inter-database plan and update an existing Percentage/Share based inter-database plan and a new Percentage/Share based plan can be configured using the Add/Remove options.

You can also view Share, Percentage Radio buttons and a drop down with Basic, Advanced options.

Note:

If the Exadata plug-in version is 12.1.0.3.0 and earlier or if the Exadata Storage Server version is 11.2.3.1.0 or earlier, the Share, Percentage based inter-database plan radio buttons are not available. You can view only Percentage-based options (that is, the drop-down only displays the Basic, Advance options).

When considering an inter-database plan:

  • If Oracle Exadata Storage Server is only hosting one database, then an inter-database plan is not needed.

  • If an inter-database plan is not specified, then all databases receive an equal allocation.

For further details on the inter-database plan, refer to the About Interdatabase Resource Management section in the Oracle® Exadata Storage Server Software User's Guide.

5.3.6 Diagnosing Exadata Cell Alerts

Enterprise Manager listens for Exadata Cell alerts sent from the Exadata Cell Management Server; so, any hardware failure or cell error will be reported in Enterprise Manager. For detailed cell error code and its interpretation, refer to the Hardware Alert Messages section in Appendix B, "Alerts and Error Messages" of the Oracle® Exadata Storage Server Software User's Guide.

5.3.7 Accessing Oracle Support Workbench for Exadata Storage Server

You can access the Oracle Support Workbench for the current Exadata Storage Server to access diagnostic data for problems and incidents related to the cell.

To access the Support Workbench for a single Exadata cell, follow these steps:

The following topics address managing your InfiniBand network:

5.5.1 InfiniBand Metric Types

Aggregate Sensor

The Aggregate Sensor takes input from multiple sensors and aggregates the data to identify problems with the switch that require attention. Whenever the sensor trips into an "Asserted" state (indicating a problem) or "Deasserted" (indicating that the problem is cleared) for a component on the switch, associated Enterprise Manager events will be generated.

Response

This is the main metric indicating availability of the InfiniBand switch. It is collected every 60 seconds by default through the management interface of the switch.

Switch Configuration

This metric captures the switch configuration. The information collected is valuable only to Oracle Support, which will use it to assist in debugging situations.

5.5.2 Performing Administration Tasks on Infiniband Networks
