In order to aquire the correct hardware for the MiddleWare machine, it is a prerequisite to use this document correctly.
When planning the deployment of a large quantity of Performance Analysis agents or when monitoring extreme environments, prior planning is required to optimally size the hosting hardware.
This task is facilitated by using a Performance Analysis sizing spreadsheet, which enables obtaining a recommendation for the middle-tier host specification, based on the monitored instances' characteristics. The spreadsheet uses an analytical methodology to propose optimal recommendation for hardware requirements.
Follow the steps below to size your middle-tier:
1. Obtain the sizing spreadsheet PADB2_Middleware_Sizing_Assistant_704v1.xls, attached to this article. The purpose of this spreadsheet is to provide a ‘best estimates’ infrastructure to support the targeted Performance Analysis installation. Quest highly recommends using this tool and the analysis of its results in conjunction with Professional Services.
2. Fill-in all requested information regarding the DB2 instances that are to be monitored by the same middle-tier host.
