Miscellaneous

It is recommended that you install the following Microsoft hotfix to avoid Operations Manager system degradation in

the long run:

Operations Manager requires an entire 4 GB of RAM for optimal performance. A typical Windows configuration

allocates 3.5 GB RAM for application activities and reserves the remaining memory for its internal use. Enabling the

PAE flag requests Windows to release its reserved cache (RAM) for application (Operations Manager) usage. For

more information about enabling the PAE flag, you can refer to

http://www.microsoft.com/whdc/system/platform/server/pae/default.mspx

It is recommended that you install a SCSI controller that has Battery Backed Write Cache (BBWC). Enabling BBWC

will provide better disk performance of the Operations Manager system.

When installing Operations Manager on Windows Server 2008, page file configuration is mandatory. The page file

shouldn’t be set to “Automatically manage paging file size”; the user should specifically define the fixed size.

Hostname and IP Address

It is recommended that you configure the hostname and IP address for the Operations Manager server before you

start installing Operations Manager. Specify the hostname when you are installing the operating system or

subsequently, using My Computer > Properties > Computer Name.

Once Operations Manager is installed, changing the hostname and IP address is a very laborious process involving

file manipulation and the execution of scripts. Refer to the User Guide for Cisco Unified Operations Manager, which

documents all the steps involved in changing the hostname and IP address of the Operations Manager server.

Note:

Make sure that the hostname does not contain any underscores.

Client PC Macromedia Flash

For any PC client (or if the Operations Manager server is also going to be used as the Operations Manager client),

please visit

http://www.adobe.com

and upgrade the Adobe/Macromedia Flash Player on the Operations Manager

server to Version 8 or later.

The client system must be used to access the Internet, and the upgrade is applied directly to that system. There is

no way to separately download this file from the Adobe or Macromedia website and apply it. If you are working in a

very secure network environment, it is recommended that you upgrade the Macromedia Flash version before

installing Operations Manager on a network that is blocked from the Internet.

Verify Locale Settings

Operations Manager only supports the U.S. English and Japanese locales. Using other locales means that you are

running on a nonsupported configuration. Further, Operations Manager may display erratic behavior, such as

JRunProxyServer services not starting automatically. However, non-U.S. English keyboard layouts should work.

DNS Settings

It is not mandatory that devices managed by Operations Manager be in Domain Name System. However, it is

mandatory that Operations Manager itself be reachable through both its fully qualified domain name

(server.cisco.com) and its IP address. This can be accomplished in either of these ways:

●

Adding a forward and reverse name translation in the DNS server for Operations Manager
