2 Preparing Your Environment

This section provides guidelines for deploying Oracle Enterprise Manager Ops Center in a way that meets your needs, explains the steps needed to verify that your systems meet the prerequisites, and provides instructions for obtaining the software.

When you have completed the planning and preparation procedures described here, you are ready to install the software.

2.1 Planning the Deployment

Before you prepare the systems for an Oracle Enterprise Manager Ops Center installation, you must plan your deployment. Your network configuration, your Internet connection policies, and the numbers and types of assets you intend to manage all affect the optimum deployment. Before installing, consider the following questions:

  1. How will you use Oracle Enterprise Manager Ops Center?

  2. Will you manage virtual assets?

  3. What type of network configuration will you use?

  4. Will you use Connected Mode or Disconnected Mode?

  5. Does your site require High Availability?

  6. Will your site use a local or a remote database?

2.1.1 About Using Oracle Enterprise Manager Ops Center

The Oracle Enterprise Manager Ops Center software provides management for hardware, operating systems, firmware and OS updates, for both physical and virtual assets. The number of types of assets, the total number of assets, and the methods you use to manage the assets all affect resource utilization.

Although the Enterprise Controller and the Proxy Controller can run on the same server, this is recommended only for a small-scale site. In most cases, your site benefits from running the Proxy Controller on a separate system. At large-scale sites, deploy a Proxy Controller on each subnet.

Note:

If you intend to provision or update Oracle Solaris 11, you must install the Enterprise Controller and at least one Proxy Controller on Oracle Solaris 11. The Oracle Solaris 11 library can only be installed on an Oracle Solaris 11 system.

Hardware Management

To monitor and manage hardware, the Proxy Controller discovers assets and then polls each asset for status and configuration changes. The Proxy Controller initiates network sessions to the hardware's systems management Ethernet port, using specific server and chassis-type protocols. Using the software to manage only hardware assets has a low resource impact on the system running the software. However, network traffic from the Proxy Controller to the assets can have a high impact. Make sure Proxy Controllers are scaled appropriately.

Hardware Management + OS Provisioning

OS provisioning is executed from the Proxy Controller. The job management system meters the number of OS provisioning jobs that can occur in parallel, but OS provisioning also creates a load on the Proxy Controllers and network. Configure a Proxy Controller on each subnet to provision the assets on that subnet. In addition, configure an NFS server close to the Proxy Controllers to store the OS images and firmware images.

Hardware Management + OS Provisioning + OS Updates

To update an OS, an Agent Controller must be deployed on the operating system and both update and provisioning jobs must be completed. The jobs include several transactions to determine the operating system's required updates and to perform the update operation. These operations increase the network utilization of the Enterprise Controller and Proxy Controllers.

Hardware Management + OS Provisioning + OS Updates + Virtualization Management

Beginning with Oracle Solaris 10 assets, you can manage virtual hosts such as Oracle Solaris Zones and Oracle VM Server for SPARC (Sun Logical Domains). Managing these virtual hosts exposes significantly large operating system metrics and increases the memory utilization of the Enterprise and Proxy Controllers. For information about deployment considerations and scaling guidelines, contact your Oracle representative.

2.1.2 About Managing Virtual Assets

The Oracle Enterprise Manager Ops Center software can manage your virtual assets, such as Oracle Solaris Zones or Oracle VM Server.

Using Zones

When you use the Oracle Enterprise Manager Ops Center software's user interface to create or discover a zone, the software has full access to the zone configuration data and can manage the zone. Zones are displayed in the Navigation tree and are labeled by type.

Do not use the software to create or manage zones if your site uses Boot Environments to update operating systems of zones. Alternate Boot Environment (ABE) is not supported for zones or for the Enterprise Controller or Proxy Controller systems.

Do not install a Proxy Controller in an Oracle Solaris 10 non-global zone if you intend to use the product to provision operating systems or firmware.

You can install the Enterprise Controller software on a non-global zone but with these constraints:

  • The non-global zone must be a whole root zone.

  • The Proxy Controller cannot be located in the same zone.

  • The Proxy Controller cannot be located in the global zone that supports the Enterprise Controller's non-global zone.

  • No Agent Controller software can be installed on the global zone that supports the Enterprise Controller's non-global zone.

Using Oracle VM Server

Use Oracle VM Server for SPARC or Oracle VM Server for x86 to create multiple virtual machines on one physical hardware system. Unlike Oracle Solaris Zones that use the same operating system in all non-global zones, virtual machines can run instances of different operating systems, or different versions of the same operating system. Each instance has its own operating system, resources, and identity.

2.1.3 About Network Configuration Types

If you intend to provision OS or firmware on target systems on a subnet, configure one Proxy Controller on each subnet and then enable DHCP services on the Proxy Controller. Proxy Controllers provide the DHCP services that support the netboot or PXE boot operations of target systems.

WAN boot is available for SPARC-based ILOM systems when the Enterprise Controller is running on an Oracle Solaris OS on either a SPARC or X86 platform. Oracle Enterprise Manager Ops Center automatically sets up the WAN boot connection. This is the default connection for SPARC-based platforms.

2.1.3.1 About Network Requirements

Use these guidelines to configure a network switch for a system running the Oracle Enterprise Manager Ops Center software.

  • Use an 8-port or 16-port Virtual LAN (VLAN) switch.

  • Discover and manage the switch.

  • If your site uses VLAN, create a separate VLAN for management and provisioning networks.

  • Disable spanning-tree protocols on the switch.

For Ethernet connectivity:

  • The management network must be a 10/100 connection.

  • The provisioning and data networks must be a 10/100/1000 (1 GB) connection.

In Connected mode, the Enterprise Controller also needs to get access to vendor Web sites to download updates or other software.

The following sections describe the communication requirements for the Oracle Enterprise Manager Ops Center software.

Network Requirements and Data Flow

At least one Proxy Controller must be installed and configured. You use the co-located Proxy Controller installed with the Enterprise Controller software or install one or more Proxy Controllers on separate systems. The following diagram shows a network configuration for a site running the Oracle Enterprise Manager Ops Center software in Connected mode and with two Proxy Controllers.

Figure 2-1, "Network Ports and Protocols for Enterprise Controller in Connected Mode" shows the network ports and protocols for the Enterprise Controller in Connected Mode.

2.1.3.2 Examples of Network Configurations

This section provides the example configurations and connectivity information for Oracle Enterprise Manager Ops Center. Other configurations are possible, such as using separate switches for each network. You can implement your network using any combination of VLANs and switches. Each network, whether management, provisioning, or data, must be assigned to separate VLANs.

Separate Management, Provisioning, and Data Networks

Environments with separate management, provisioning, and data networks have the following characteristics:

  • Separate networks provide the highest security and the lowest number of points of failure.

  • Additional NICs are needed to support this configuration.

2.1.4 About Connection Modes

The Oracle Enterprise Manager Ops Center software operates in either Connected mode or Disconnected mode. Because you can change modes easily, you can also consider using a combination of Connected and Disconnected modes to maintain your data center. You can run the software in Disconnected mode until you need to access the Knowledge Base or third-party sites and then change to Connected mode. For example, to check for OS updates, change the Enterprise Controller to Connected Mode, connect to the Internet to check the Knowledge Base, and then return the Enterprise Controller to Disconnected Mode.

Connected Mode

The Enterprise Controller connects to the Internet to download OS updates, Oracle Solaris images, and updates for the Oracle Enterprise Manager Ops Center software itself. This mode of operation is called Connected mode and is the default setting. If your site policy does not allow an Internet connection, use operate Ops Center in Disconnected mode.

Figure 2-6, "Enterprise Controller in Connected Mode" shows the Enterprise Controller in Connected Mode.

Figure 2-6 Enterprise Controller in Connected Mode

Description of Figure 2-6 follows
Description of "Figure 2-6 Enterprise Controller in Connected Mode"

Disconnected Mode

Disconnected mode enables you to use the Oracle Enterprise Manager Ops Center software in a secured environment without Internet access. To support provisioning and updating functions, you must load images and updates to the Enterprise Controller manually. Because the Enterprise Controller does not download new software automatically, you must plan how and when your site obtains updated software.

To obtain updates, images, and metadata, you run a product script on an Oracle Solaris or Linux system that is allowed to be connected to the Internet, download a static version of the Knowledge Base (KB), and copy it to the Enterprise Controller. For other supported operating systems, you can obtain software in a media format such as a DVD, and upload the software to the Local Content section of the product's software library.

Figure 2-7, "Enterprise Controller in Disconnected Mode" shows the Enterprise Controller in Disconnected Mode.

Figure 2-7 Enterprise Controller in Disconnected Mode

Description of Figure 2-7 follows
Description of "Figure 2-7 Enterprise Controller in Disconnected Mode"

2.1.5 About High Availability

The design for a High Availability (HA) architecture must consider all single points of failure, such as power, storage, and network connectivity in addition to the software.

2.1.5.1 About High Availability for the Enterprise Controller

You can use Oracle Clusterware to configure high availability for your Enterprise Controller. Oracle Clusterware lets you configure two or more Enterprise Controller systems and switch between them. The user interface uses a virtual IP address (VIP), which always connects to the active Enterprise Controller.

For more information about Oracle Clusterware, see the Oracle Clusterware documentation at http://www.oracle.com/pls/db111/homepage.

Requirements for High Availability

  • Each system in the cluster must be of the same model and configured identically:

    • Processor class

    • Number of cores (at least four)

    • Amount of memory (at least 8 GB)

    • Amount of disk space (at least 100 GB)

    • Amount of swap (at least 16 GB, no less than memory)

    • Operating system - Must be Oracle Linux 5.6 or 5.7 or Red Hat Enterprise Linux 5.6 or 5.7

    • Oracle Enterprise Manager Ops Center software version, including updates

    • Network interfaces that are cabled identically to the same subnets

    • The name service used on each system must be the same

  • Configure one shared private network. Gigabit speed is recommended.

  • Configure at least one shared public network. Gigabit speed is recommended.

  • Make the following public network addresses available:

    • <node#>-vip - One address of this format should be available for each node.

    • cluster SCAN address

  • Configure a shared storage solution. This can be:

    • A shared NFS filesystem configured for root access by each node.

    • Shared SAN storage with at least one FibreChannel LUN connected to each server with identical /dev/dsk and /dev/rdsk names.

Limitations

  • User accounts and data that are not associated with Oracle Enterprise Manager Ops Center are not part of the failover process. Only Oracle Enterprise Manager Ops Center data is moved between the primary and secondary Enterprise Controllers.

  • UI sessions are lost on failover.

  • The HA configuration applies only to the Enterprise Controller and its co-located Proxy Controller and not to other standalone Proxy Controllers.

2.1.5.2 About High Availability for Proxy Controllers

High availability for Proxy Controllers is a feature of the software. When a Proxy Controller goes offline, you can migrate the Agent Controllers and assets associated with the Proxy Controller to a different Proxy Controller if one is available, or leave them if you expect the Proxy Controller to come back online.

2.1.6 About Database Options

Oracle Enterprise Manager Ops Center stores product data in an Oracle Database Enterprise Edition database. This database can be an embedded database installed on the same system as the Enterprise Controller, or a customer-managed database that is accessible to the Enterprise Controller system. If you plan to implement high availability for the Enterprise Controller, you must use a customer-managed database.

The backup option described in the Oracle Enterprise Manager Ops Center Administration Guide can be used to back up an environment with either an embedded or a customer-managed database. If you are using a customer-managed database, you can also back up the database schema using the existing backup and recovery processes implemented by your database administrator.

Note:

Runing any database other than the Oracle Enterprise Manager Ops Center database on the Enterprise Controller system is not recommended.

2.1.6.1 Preparing for an Installation with an Embedded Database

To prepare for an installation with an embedded database, you must verify that the Enterprise Controller system meets the requirements for an Oracle Database Enterprise Edition installation. These requirements are documented in more detail in the Oracle Database Enterprise Edition documentation.

You must also download the installation bundles for Oracle Database Enterprise Edition version 11.2.0.3. These files are available on My Oracle Support (MOS).

2.1.6.2 Preparing for an Installation with a Customer-Managed Database

To prepare for an installation with a customer-managed database, you must identify a system that meets the following requirements:

  • System uses Oracle RDBMS 11.1.0.x or higher

  • Network latency is minimal between the EC and the database server

  • System has 4 GB of physical memory, or 6 GB of physical memory if you plan to use a co-located Proxy Controller

These requirements are documented in more detail in the Oracle Database Enterprise Edition documentation at http://www.oracle.com/technetwork/database/enterprise-edition/documentation/index.html.

If you are implementing high availability, the remote database system must be accessible for all of the Enterprise Controller nodes.

2.2 Preparing The Systems

Once you have planned your installation, you must prepare the systems for installation. Verify that your Enterprise Controller and Proxy Controller systems meet the system requirements, verify that you have the required account access, and verify that your directories are properly configured for Oracle Enterprise Manager Ops Center storage.

2.2.1 Checking the System Requirements

Before installing Oracle Enterprise Manager Ops Center, verify that the Enterprise Controller and Proxy Controller systems meet the prerequisites. The OC Doctor utility can check a system to verify that it meets all of the prerequisites for an Enterprise Controller or Proxy Controller system.

The Oracle Enterprise Manager Ops Center software requires a full installation of Oracle Linux or Red Hat Enterprise Linux. When you install the operating system, install all optional software components in every software category except the Language category. Set the SELinux security setting to Disabled.

You can install Agent Controllers on a wide set of operating systems, including Oracle Enterprise Linux, Red Hat Enterprise Linux, and Oracle Solaris.

See the Oracle Enterprise Manager Ops Center Certified Systems Matrix for lists of supported operating systems for Agent Controller installation and management, hardware and other technologies supported for management, and browsers supported for accessing the UI.

    The OC Doctor displays a warning and a suggested solution for each issue.

  5. Correct any issues discovered by the OC Doctor utility.

2.2.1.3 Checking Cache Requirements

The Oracle Enterprise Manager Ops Center software uses a central file cache for the following types of content:

  • For provisioning hardware or an OS:

    • Firmware

    • OS Images

  • For updating assets:

    • Knowledge Base metadata that specifies the updates for an OS distribution

    • Packages, patches, and RPM files that are a standard part of an OS update distribution

    • Custom content for a site such as software bundles, configuration files, or scripts.

The software propagates content from the cache. For example, a Proxy Controller downloads content from the Enterprise Controller, and an Agent Controller downloads content from the Proxy Controller. After content is cached, it can be re-used without additional download operations.

Cache Recommendations for Connected Mode Configurations

The minimum cache size is 74 GB on Enterprise Controllers and Proxy Controllers. Increase the minimum cache size based on the following guidelines:

  • 2 GB for software installation (in /opt and /var/tmp)

  • 4 GB for each OS image used for provisioning

  • 10 GB for each distribution for updates

Because Agent Controllers store only update content for their OS instance, they have reduced caching requirements. Allow 2 GB for both the software and the update cache.

Example 2-1 Updating Several Operating System Assets

A user runs a job which updates five Oracle Solaris 10 SPARC OS Agent Controllers managed by a single Proxy Controller. The Proxy Controller downloads and caches all of the patches required by the Agent Controllers. Each Agent Controller downloads and caches the patches it requires. If an Agent Controller has cached several updates already, it re-uses those updates and downloads only what it needs from the Proxy Controller.

Example 2-2 Provisioning an Operating System Asset on Several Servers

A user runs a job to provision an OS image to three systems which are managed by two Proxy Controllers. Each Proxy Controller downloads and caches the image. The three systems do not cache the OS image, because they download and install the images from their respective Proxy Controllers.

The installations can use the co-located Proxy Controller, installed on the same OS instance as the Enterprise Controller. The Proxy and Enterprise Controllers share a global file cache so no additional disk space is required for the Proxy Controller's cache.

Example 2-3 Provision and Update Different Operating Systems on Several Servers

A site uses an Enterprise Controller with a co-located Proxy Controller and one other Proxy Controller, which together do the following:

  • Provision Oracle Solaris 10 X86 and SPARC 10/08 and Oracle Linux 5.5, using one ISO image for each distribution.

  • Update the Oracle Solaris 10 X86, Oracle Solaris 10 SPARC and Oracle Linux 5 32-bit X86 distributions. The remote Proxy Controller provisions and updates Oracle Solaris 10 systems on both SPARC and X86 architectures.

Both the Enterprise Controller with its co-located Proxy Controller and the remote Proxy Controller need a cache size of 74 GB, with 2 GB in /var/tmp and /opt, and 72 GB in /var/opt/sun/xvm. No additional caching is required on the Enterprise Controller because the co-located Proxy Controller shares its cache. The Enterprise Controller must have a minimum cache size of 44 GB:

  • 30 GB for the three OS update distributions in /var/opt/sun/xvm

  • 12 GB for the three OS images in /var/opt/sun/xvm

  • 2 GB for the software in /var/tmp and /opt

The remote Proxy Controller must have a minimum cache of 30 GB:

  • 20 GB for the two Oracle Solaris OS update distributions in /var/opt/sun/xvm

  • 8 GB for the two Oracle Solaris OS images in /var/opt/sun/xvm

  • 2 GB for the Ops Center software in /var/tmp and /opt

Cache Requirements for Disconnected Mode Configurations

In Disconnected mode, the Oracle Enterprise Manager Ops Center software performs without an Internet connection. Images are managed in the same way as in Connected mode except it is not possible to download Oracle Solaris OS images. Administrators must cache images manually. For OS updates content, administrators must obtain and upload the content:

  • The Knowledge Base content is available as an archive file, which users can obtain by running the harvester script. Depending on the settings, users can download the KB content only, or they can obtain content for one or more Oracle Solaris baselines.

  • Patches, packages, or RPMs must be uploaded to the Enterprise Controller.

Proxy Controllers and Agent Controllers function the same way in both Connected and Disconnected modes and their cache requirements are the same.

2.2.1.4 Checking Disk and Swap Space

The Oracle Enterprise Manager Ops Center software requires the following minimum values for disk and swap space:

  • At least 70 GB of available disk space after the operating system has been installed

  • At least 6 GB of swap space

    Note:

    The swap requirement might be higher if you are using an embedded database. The requirements for a embedded database are documented in the Preparing for an Installation with an Embedded Database section.

2.2.1.5 Checking Values for kernel.shmall and kernel.shmmax

If the /etc/sysctl.conf file has been modified, the values of kernel.shmall and kernel.shmmax might be too small, which causes the product installation to fail. The following values are recommended:

  • kernel.shmall: 268435456

  • kernel.shmmax: 4294967295

2.2.1.6 Editing Kernel Settings

When you install Linux, the Xen kernel is set as the default kernel. Setting the standard kernel as the default kernel improves performance. Perform the following procedure on each Enterprise Controller and Proxy Controller system.

  1. Edit the /boot/grub/menu.lst file.

    # vi /boot/grub/menu.lst
    
  2. Set the value of default to 1.

    default=1
    
  3. Save the file.

  4. Shut down the system.

    # shutdown -r now
    

    The system now uses the standard kernel by default.

2.2.2 Verifying Account Access

Log into My Oracle Support or register for an account and log in.

To update SUSE Linux systems, you must have a Novell account. Verify that your Novell account allows access to software updates.

2.2.3 Configuring Storage

The /var/opt/sun/xvm/osp/share/allstart directory is configured as an NFS share. If you use ZFS to provide the file system that mounts as /var/opt/sun/xvm, do not use the ZFS sharenfs command to share /var/opt/sun/xvm/osp/share/allstart so that the Oracle Enterprise Manager Ops Center software can use legacy NFS sharing tools to share the /var/opt/sun/xvm/osp/share/allstart directory.
