These release notes are for CiscoWorks Network Compliance Manager (NCM) 1.6.03.
CiscoWorks NCM 1.6.03 is a patch release that you can install on top of CiscoWorks NCM 1.6 or Ciscoworks NCM 1.6.01 or Ciscoworks NCM 1.6.02.
Note The Docs tab provided in the CiscoWorks NCM user interface might not include links to the latest documents. Therefore, we recommend that you access the CiscoWorks NCM documentation set using the following URL: http://www.cisco.com/en/US/products/ps6923/tsd_products_support_series_home.html
This document contains the following sections:
CiscoWorks NCM tracks and regulates configuration and software changes in a multivendor network environment. It provides visibility into network changes and tracks compliance with a broad variety of regulatory, IT, corporate governance, and technology requirements. CiscoWorks NCM helps IT staff identify and correct trends that could lead to problems, such as network instability and service interruption.
CiscoWorks NCM is integrated with CiscoWorks and is initially launchable from the CiscoWorks home page. CiscoWorks NCM is interoperable with other CiscoWorks applications, such as the LAN Management Solution (LMS) bundle through the Common Services Device Credential Repository (DCR).
Installing the CiscoWorks NCM 1.6.03 Patch
To install the CiscoWorks NCM 1.6.03 patch:
Step 1 Unzip the patch bundle on the CiscoWorks NCM server.
Step 2 Run the patch script.
For Windows, execute the patch.bat script from the command line.
For Linux or Solaris, execute the patch.sh script using the following commands:
% sh patch.sh
A log file named patch.log is created in the <CWNCM_Install_Directory>/server/log/ directory, when the patch script is executed. The errors that occur during the installation process are logged in the patch.log file.
The patch installer creates a subdirectory named patch_backups in the root of the CiscoWorks NCM installation directory. This subdirectory includes a directory with the patch build number. The files that are changed by the patch installer are backed up in this directory. The backup.log file lists the files that are backed up and the original location of the files.
To remove the patch and roll back to the pre-patch state:
Step 1 Stop the NCM Management Engine.
Step 2 Restore the files that are changed by the patch installer to their original locations.
Step 3 Restart the NCM Management Engine.
What's Been Fixed in CiscoWorks NCM 1.6.03
Table 1 describes the issues fixed in CiscoWorks NCM 1.6.03.
Table 2 shows the supported platforms for CiscoWorks NCM 1.6.x.
Table 2 Supported Platforms for CiscoWorks NCM 1.6.x
Operating System Architecture 32-bit 64-bit 1
Windows Server 2008 R2
Windows Server 2003 SP2
RedHat RH AS 44
RedHat RHEL Server 5
SuSE Enterprise Linux Server 10
1 CiscoWorks NCM 1.6 full installs are supported only on 64-bit architecture. You can upgrade from an existing 32-bit CiscoWorks NCM platform to a 64-bit platform. If you are using a RHEL 5 Server x64, it is required that you upgrade to 64-bit platform.
2 Before installing CiscoWorks NCM 1.6 on a Solaris 10 platform, you must reconfigure the Syslog server on Solaris 10 to ignore the remote Syslog messages. The Solaris Zone on which CiscoWorks NCM runs must use a dedicated Network Interface Card (NIC).
3 A large amount of swap space is required due to the fork() system call on Solaris. When you fork a 24 GB process, Solaris allocates 24 GB in the swap file. If the 24 GB is not available in swap, the fork() system call fails.
4 The last supported CiscoWorks NCM version on this platform is CiscoWorks NCM 1.5.x.
The following operating systems are no longer supported:
•Red Hat AS3
Note For all operating system upgrades, please see the respective vendor documentation or contact your system support personnel. Cisco is not responsible for issues that might arise during third-party product upgrades.
Table 3 shows the databases that are supported by CiscoWorks NCM 1.6.x.
Except for modest deployments without full enterprise scale and performance requirements, the application server and database server should be on separate physical machines. In addition, the database server should be dedicated to CiscoWorks NCM, rather than serving multiple applications.
Note CiscoWorks NCM 1.6 does not support the use of Microsoft SQL Named Instances.
The following databases are no longer supported:
•Oracle 9i and Oracle 9.2
•Microsoft SQL Server 2000
Note For all database upgrades, please see the respective vendor documentation or contact your database analyst. Cisco is not responsible for issues that might arise during third-party product upgrades.
Additional CiscoWorks NCM Configurations
If you have configured a High Availability Distributed System, the database requirements for Oracle and Microsoft SQL Server include:
If you have configured a Horizontal Scalability environment, the database requirements for Oracle and Microsoft SQL Server include:
See High Availability Distributed System Configuration Guide for CiscoWorks Network Compliance Manager for information on configuring High Availability Distributed System environment.
See Horizontal Scalability User Guide for CiscoWorks Network Compliance Manager for information on configuring Horizontal Scalability environment.
Note High Availability and Horizontal Scalability environments are not supported for MySQL.
Note the following points while running CiscoWorks NCM in a virtual environment:
•VMWare guests can be run on a VMWare ESX 3.5 or VMWare ESX 4.0 server (preferred). It is important that the Disk I/O be split. The ESX server must have two arrays, one for the ESX operating system and one for the virtual machines.
•Use of Vmotion is not recommended.
•If you plan to use virtual machines for both CiscoWorks NCM and your database, ensure that they are running on different VMWare Guests. Note that this only works if you set a limit on managed devices and keep it low. It is recommended that you have the database on a different ESX host so there is no conflicting I/O on the array.
•If you plan to run VMWare in a Distributed System or Horizontal Scalability environment, the maximum number of CiscoWorks NCM Cores should not exceed two.
•Some VMWare Guests time drift. Syncing to an external time source can solve this issue.
The CiscoWorks NCM VMWare Guest system requirements are double that of standalone server requirements.
CiscoWorks NCM can be network intensive, therefore, if you have many virtual machines sharing a virtual switch and network interface card, you could experience unexpected behavior, including time-outs and failed tasks. In addition, each virtual environment is different and could function differently under loads with shared VM Guests.
If you there any performance issues while running CiscoWorks NCM in a virtual environment, do the following:
•Increase hardware resources
•Ensure that resources are dedicated through your ESX Administrator
•Decrease the number of VMWare Guests running simultaneously
•Add a dedicated network interface card to the ESX server for CiscoWorks NCM to use exclusively
Significant performance degradation has been seen on ESX servers running multiple virtual machines where one or more virtual machine was under heavy load. It is critical that the ESX server running CiscoWorks NCM in a virtual environment be properly resourced to avoid performance degradation.
Note The number of managed devices does not have as significant of an impact on performance as the number of concurrent tasks. If performance issues are seen, reduce the number of concurrent tasks and ensure that CiscoWorks NCM is getting the appropriate resources.
Additional Required Applications
You need to install the following applications:
•CiscoWorks NCM supports the following browsers:
–Mozilla Firefox 3.x and higher
–Internet Explorer 7.x and higher
