Minimum Disk Space Requirements
Planning the Installation
Cisco Performance Visibility Manager (PVM) provides server-side components and processes deployed to a single host within the required operating environment. The client-side application is an HTML-based Graphical User Interface (GUI) accessed through a supported web browser.
Note
Details of the Cisco PVM operating environment and system installation are included in Chapter 2, "Installation Requirements".
This chapter contains the following topics:
•
Installation Process
The installation process is automated using Cisco PVM installation software on a dedicated server. The installation software installs all components and sets the environment to run Cisco PVM with minimum user interaction.
The Cisco PVM installation requires root-level access to a Linux server that has been configured in accordance with the operating environment requirements specified in Chapter 2, "Installation Requirements". The automated installation process performs the following steps:
1.

LDAP Authentication
By default, Cisco PVM relies on its own authentication and authorization repository created during installation. After installation, the system can be configured to use a Lightweight Directory Access Protocol (LDAP) server for user authorizations.
Cisco PVM supports the following LDAP versions:

Note
Existing Installations
If the installer finds a previous version of Cisco PVM running, it will ask you to stop Cisco PVM and reinstall. If an existing installation is found and Cisco PVM is not running, Cisco PVM will ask you if you want to remove the installation and directories. If you answer yes, the installer performs the necessary actions and continues with the installation. If you answer no, installation is terminated.

Installation Location
The installation software will prompt you to specify the desired location for the Cisco PVM application. The application is, by default, installed to /opt/CSCOpvm. You can accept this default location by pressing Enter. Alternately, you can override the default by entering a different installation path.
Oracle Installation Location
The installation software will prompt you to specify the desired location for the Oracle application installation. The application is, by default, installed to /opt/CSCOpvm/oracle. You can accept this default location by pressing Enter. Alternately, you can override the default by entering a different installation path.
Data Storage Location
The installation software prompts you to specify the desired location for the Cisco PVM database files. The database files, by default, will be installed to /opt/CSCOpvm/oradata. You can accept this default location by pressing Enter. Alternately, you can override the default by entering a different database data path.
Required Hardware
Cisco PVM supports a maximum of 200 NAM-2 blades, which is approximately equivalent to 100 NAM-2s plus 300 NM-NAMs. The hardware requirements for Cisco PVM installations differ depending on the number of NAMs your system is intended to support. The requirements are broken down into three configurations:
•

Table 1-1 provides a summary of the recommended minimum requirements for large, medium, and small configurations.
Note
Minimum Disk Space Requirements
The installer will check to ensure that the specified installation directories have the recommended amount of free disk space available. Table 1-2 provides a summary of the recommended minimum requirements for free disk space.
Note
The default database directory is /opt/CSCOpvm/oradata (you can override the default by entering a different installation path), and the installation defaults to a predefined database size.
The installation software checks to ensure that the specified installation path contains sufficient space to support the installation. The installation aborts in the event of insufficient disk space availability.
•
•
Installation Logs
The installation software provides status messages during the installation. These messages are provided to the console and are also written to a log. Additionally, errors related to the application and database installations are raised to the console and written to the respective log files located at installation directory]/logs.
Note
Oracle Installation
Cisco PVM runs using 32-bit Oracle. The installation DVD includes Oracle 9i Standard Edition, and the installation software assigns Oracle variable values.
Caution
Oracle Password Changes
Changes to the Oracle database passwords, normally done by the DBA, are not recommended. Cisco PVM has specific passwords that are required for product support.
Temporary File Cleanup
Upon successful installation, Cisco PVM cleans up all temporary files.
