CA IDMS/DB Analyzer Parameter Statements

This chapter describes how to use CA IDMS/DB Analyzer parameter statements.

CA IDMS/DB Analyzer performs two basic functions: Statistics accumulation and report production. These two functions can be performed for any subschema by using a single PROCESS parameter statement.

The PROCESS statement can be used alone to generate a complete set of statistics and reports.

You can also limit or modify these functions by using three additional parameter statements: AREA, SET, and REPORT. These optional statements allow you to limit or modify the statistics collected, and to specify which reports you want generated.

The PROCESS statement initiates CA IDMS/DB Analyzer processing. It is a mandatory statement and must be entered first. By specifying a process and a subschema name, you can automatically analyze the entire database described by the subschema. Or, if you need to analyze only part of the database, you can specify explicitly the areas, sets, index sets and/or reports that you want to process.

You can use the PROCESS statement to:

• Request the accumulation of statistics, the production of reports, or both
• Specify the subschema to be analyzed
• Select either the AUTOMATIC or the EXPLICIT processing mode
• Request comparative reports
• Create a file of logically deleted record(s)(LDEL)

Before CA IDMS/DB Analyzer processes a database, you can check the syntax of your parameter statements by choosing the SYNTAX option in the PROCESS statement.
