What is XINFO?

• XINFO analyzes z/OS data: JCL, DB2, SMF, TWS, Control-M, CA-7, RMM, Cobol, PL/1, Assembler, CICS, DLI, IMS, Control-D, CA-1, Zeke and much more...

• XINFO analyses UNIX and Windows data: Volumes, files, hardware, software, services, daemons, job and program run times, Java sources, TWS, Control-M, Automic and SAP

• XINFO loads the result into a database

• XINFO has dialogs to query and visualize the data

XINFO is an IT information system. It enables you to

cross reference data from various systems.

Using XINFO

• Which jobs use file A.B.C?

• Which jobs use program PGM1?

• Which scripts are calling the FTP?

• Which program calls subprogram XYZ?

• When was file A.B.C used in which jobs?

• Which DB2 tables are used in which jobs?

• Which programs are using which includes?

• Which jobs were active last Monday at 3.30?

• ...

A major part of daily work consists of gathering up information. XINFO enables you to access that information. Some typical questions are:

XINFO Source Scanner

• General Info: Basic information like “uses static SQL”, “uses dynamic SQL”, “calls CICS”

• Includes: Usage of includes and copy members

• Calls: External program calls (tables and graphics)

• Files: Access type (e.g. read/write) and definition (file names, record length etc.)

• DB2: Which program uses which tables (select, insert, delete, etc.), and columns

• CICS and DLI: Calls and their parameters

• Variables: Definitions and usage

• Comments

XINFO’s source scanners are analyzing program source

code to deliver the following information:

HORIZONT 25 XINFO®

XINFO Source Scanner

• PDS/PDSE

• Librarian

• Source path (Java)

• Compile listings

• Selection:

- Complete libraries ( Source plus include/copy)

- Specific members specified by name patterns (include/exclude)

• Full scans or incremental updates, e.g. all changed programs

Following data can be input to the source scanners:

HORIZONT 26 XINFO®

• Input are the results of the individual scanners

• The results are three tables (Calls, File- and DB2-Access)

- Including nested callsprogram A calls B, B calls C, as a result A calls C on level 2

- Language independent No matter if A is COBOL and B is ASM

- Supports development “staging” Test program may call production module, but not vice versa

XINFO Program Calls In addition to language specific data (COPY, variables)

XINFO offers “multi language call analysis”
