WebSphere MQ Resources

RequirementsRequirementsYour LifeKeeper configuration must meet the following requirements prior to the installation ofthe WebSphere MQ Recovery Kit. Please see the LifeKeeper for Linux Planning and InstallationGuide for specific instructions regarding the configuration of your LifeKeeper hardware andsoftware.Hardware Requirements• Servers. The Recovery Kit requires two or more servers configured in accordance with therequirements described in the LifeKeeper for Linux Planning and Installation Guide. See theRelease Notes for supported Linux distributions.• Data Storage. The WebSphere MQ Recovery Kit can be used in conjunction both withshared storage and with replicated storage provided by the LifeKeeper Data Replicationproduct or DRBD. It can also be used with network-attached storage (NAS).Software Requirements• LifeKeeper software. You must install the same version of LifeKeeper software and anypatches on each server.• LifeKeeper IP Recovery Kit. You must have the same version of the LifeKeeper IPRecovery Kit on each server.• IP network interface. Each server requires at least one Ethernet TCP/IP-supported networkinterface. In order for IP switchover to work properly, user systems connected to the localnetwork should conform to standard TCP/IP specifications.Note: Even though each server requires only a single network interface, you should usemultiple interfaces for a number of reasons: heterogeneous media requirements, throughputrequirements, elimination of single points of failure, network segmentation, and so forth.• TCP/IP software. Each server also requires the TCP/IP software.• WebSphere MQ software. IBM WebSphere MQ must be ordered separately from IBM. Seethe LifeKeeper Release Notes for supported WebSphere MQ versions. The WebSphere MQSoftware must be installed on each server of the cluster prior to installing the WebSphereMQ Recovery Kit. The following WebSphere MQ packages must be installed to successfullyinstall the WebSphere MQ Recovery Kit:MQSeriesServer, MQSeriesSamples, MQSeriesClient, MQSeriesRuntime, MQSeriesSDK• Optional C compiler. The WebSphere MQ recovery kit contains a modified amqsget0.csample program from the WebSphere MQ samples package. This program has been modifiedto work with a timeout of 0 seconds instead of the default 15 seconds. It is used to performPUT/GET tests for the queue manager. This program is compiled during RPM installationand therefore a C compiler must be installed and must be located in the PATH of the “root”user.• Syslog.pm. If you want use syslog logging for WebSphere MQ resources, the Syslog.pmPERL module must be installed. This module is part of the standard PERL distribution and isnot required to be installed separately.6 WebSphere MQ Recovery Kit Administration Guide
