Analysis function overview
Using the ANALYZE command, subcommands, and keyword parameters, you can perform the following tasks:
Analyze information about single or multiple areas
Validate pointer data
Set thresholds for exception condition detection
Retain data in a statistics repository
Retrieve the data for historical reporting
Generate input to the Area Change Modeling Utility feature
The analysis function analyzes and validates the content and structure of DEDBs. The function can analyze an area data set or an image copy of an area data set. The analysis function includes the following features:
Keywords and keyword parameters let you control and customize the analysis.
The validation function examines and validates pointer data during every analysis.
The analysis function computes statistics and analyzes information about single or multiple areas and presents the results in reports.
User-specified values set threshold criteria by which to perform analysis to detect exception conditions.
The statistics repository can store information for historical reporting.
Fast Path Analyzer/EP includes the following utilities that can use input from the analysis function to improve database performance and integrity:
|Area Change Modeling Utility|
The Area Change Modeling utility lets you model a potential DEDB change before performing it.
|SDEP Space Utilization Utility|
The SDEP Space Utilization Utility lets you track usage of the SDEP portions of your area.
|Control Interval Dump and Modification Utility|
The command-driven Control Interval Dump and Modification Utility lets you dump, inspect, verify, or modify the entire contents of a database control interval (CI). This utility can be used to repair pointer errors and VSAM control information even when standard VSAM utilities do not provide access to the data. This utility can also be used to print the contents of the DMAC block for an area.
