Resource Governor Overview

Resource Governor provides Information Systems (IS) organizations with the ability to easily manage the growing volume and unpredictable nature of ad hoc data access. Together with its partner product, Resource Analyzer, Resource Governor is specifically designed to help IS organizations analyze and control end-user data access, as well as provide site-specific control options.

Since the Web is now the medium of choice for disseminating enterprise information among many corporations, understanding user and usage data is critical. The Web environment exposes systems to more access of data by an increasing number of users. This places increased stress on data warehouses, self-service applications, and corporate communications applications. For this reason, it becomes crucial to tune applications for high performance, high availability, and fast response times.

Resource Governor monitors data usage activity by collecting the attributes of requests and storing them in a set of Usage Monitoring tables. An administrator defines site-specific thresholds controlling the amount of resources a request can use. Based on this usage and threshold information, Resource Governor builds rules on how to govern requests against specific data sources. The governing facility uses the rules when inspecting each request, stopping any request that is estimated to exceed the predetermined resource thresholds.

Resource Governor controls monitoring, system configuration parameters, and governing rules. It provides preemptive governing for requests issued to both relational and non-relational data sources.

You can use Resource Governor to monitor, govern, and report from multiple servers in a distributed data warehouse environment.

Note: We use the term MVS to refer to z/OS - PDS deployment and z/OS to refer to z/OS - HFS deployment using UNIX System Services.
