Introduction to the IBM Application Development Tools on z/OS and OS/390

Listing

This is the standard output file from a compile (or the ADATA file from a High

Level Assembler program).

Side file

This is a highly condensed form of the compiler listing, produced by a Fault

Analyzer utility after a compile.

In 6.3.3, “How to create a side file” on page 195, we show you how to create a

side file. We give some further insights into their usefulness in 9.3.4, “Steps

toward integration” on page 337.

1.3.4 User exits

Fault Analyzer provides you with entry points to user exits, which can be written

to perform a variety of tasks when application program errors occur. These user

exits include the ability to:

򐂰 Reformat a dump to include site-specific information.

򐂰 Send users messages about the abending job.

򐂰 Suppress duplicate dumps and record the number of instances.

We provide you with samples of two REXX user exits for you to use

as is or to

modify for your needs.

1.3.5 Latest software update

The latest Program Temporary Fix (PTF) for Fault Analyzer for z/OS and OS/390

V3R1M0 is UQ69985.

The user’s guide and reference documentation is available on line through the

Help action on the main menu, or can be downloaded from the library on the

Web.

1.4 IBM File Manager

IBM File Manager provides powerful functions for an application programmer to

use. However, even operations support personnel or systems programmers will

find it useful.

1.4.1 Three features

File Manager comes in three features (MVS, DB2 and IMS).

8 Update on the IBM Problem Determination Tools

File Manager MVS feature

The product’s utilities provide the ability to:

򐂰 Browse, edit, copy, and print:

– QSAM data sets

– VSAM data sets

– PDS members

򐂰 Work with data formatted according to record structure, arranged into fields

򐂰 Edit entire files, regardless of size

򐂰 Work with files containing multiple record structures

򐂰 Use flexible criteria to select records

򐂰 Find and change data within particular fields

򐂰 Identify records that do not match a recognized structure, or that contain

invalid values

򐂰 Create data with fields initialized according to flexible patterns

򐂰 Automate tasks in batch jobs, using File Manager functions and REXX

procedures

򐂰 Compare data sets using templates

File Manager DB2 feature

This feature extends the capabilities of File Manger to work with DB2 data:

򐂰 All of the standard File Manager functions are available, specifically designed

for manipulating DB2:

– Browse

– Edit

– Print

– Copy

򐂰 You get to select the DB2 subsystem you want to work with.

򐂰 You can list DB2 objects in the system catalog.

򐂰 You have the ability to export and import DB2 tables and views.

򐂰 You can generate JCL and utility control statements for the following utilities:

– Copy

– Load

– Rebuild

– Reorg

– Runstats

Chapter 1. Application development tools for z/OS and OS/390 9

򐂰 You have the ability to prototype SQL SELECT statements using basic or

advanced support.

򐂰 You can perform statement analysis using the EXPLAIN facility.

File Manager IMS feature

This feature extends the capabilities of File Manger to work with IMS data.

You can use File Manager IMS to:

򐂰 Browse, edit, or print data in an IMS database

򐂰 Extract from, or load data into, an IMS database

For many tasks, you can use the File Manager IMS features called templates and

views. These allow you to define a logical view of a data set based on a COBOL

or PL/I copybook. Associating a view with a data set lets you define which fields

and records you want to work with, how the fields are displayed, and which

segments are displayed.

1.4.2 Online processing

The three features of File Manager (MVS, DB2 and IMS) use a standard ISPF

interface as shown in Figure 1-4.

Two key elements of File Manager enable you to perform advanced or very

detailed data manipulation:
