What is the Availability Manager?What is the Availability Manager?
A real-time monitoring, diagnostic and correction tool for OpenVMS
A DECamds equivalent that runs on OpenVMS Alpha and Windows
Uses a PC-type interface for easy access to data
Collects and displays data even when nodes are hung

AM InstallationAM Installation
OpenVMS Alpha
– Download and install Java 1.1.8 first
– Download and install AM (a PCSI kit) Read the installation instructions for setup information
– Insert the following line in the LOGIN.COM of the accounts that will run AM:
$ @SYS$MANAGER:JAVA$SETUP
– AM and DECamds can be installed on the same machine

AM Running EnvironmentAM Running Environment
The Data Analyzer and the Data Collector communicate by a private Ethernet protocol
– Independent of a node’s IP or DECnet software
– The protocol is not routable The Data Analyzer must be on the same LAN as the
Data Collector(s) Routers can be configured to bridge the protocol
– Protocol ID: 08-00-2B-80-48
» (08-00-2B - DEC prefix, 80-48 - protocol ID)
– Multicast Address: 09-00-2B-02-01-09

AM Running EnvironmentAM Running Environment
AM Group name
– Groups various nodes together
– All nodes in an OpenVMS Cluster need to be in the same group for proper collection of cluster data
Security
– The Data Analyzer must send a valid AM password to the Data Collector for the Data Collector to send information back to the Data Analyzer
