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

Availability Manager - TermsAvailability Manager - Terms

AM or AvailMan

– Short for Availability Manager

Data Analyzer

– GUI front-end and data analysis

Data Collector

– Called Data Provider for DECamds product

– A device driver that shows up as device RMA0:

AM and DECamds - A closer lookAM and DECamds - A closer look

DECamds (AMDS for short)

– Initial product offering

– Data Analyzer is a Motif-based application Runs on VAX and Alpha platforms Runs under OpenVMS V6.2 - V7.3

17


DECamds (cont’d)

– Data Collector Consists of an OpenVMS device driver,

configuration and startup files Enables data collection even on a hung system Runs on VAX and Alpha platforms Runs on OpenVMS V6.2 through V7.3

18


AM

– Eventual successor to the DECamds product Functional enhancements will be made to AM only

– Data Analyzer is a Java-based application Runs on OpenVMS Alpha V7.1 through V7.3,

Windows NT V4 and Windows 2000 platforms

– Gathers data from: OpenVMS nodes using the Data Collector

19

AM InstallationAM Installation

Windows NT

– Standard InstallShield installation

– Assumes one person per PC AM configuration data is stored in

the installation directory

20

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

21

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

22

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

23

AM Data Collector SetupAM Data Collector Setup

Use the AM V1.4 installation kit to install the Data Collector

Set up a group name in SYS$MANAGER:AMDS$LOGICALS.COM

Set the security password(s) in SYS$MANAGER:AMDS$DRIVER_ACCESS.DAT

Add the following to the system startup procedure: $ @SYS$STARTUP:AMDS$STARTUP START
