4. What is XINFO?
XINFO is an IT information system. It enables you to cross reference data from various systems.
XINFO analyses 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, job and program run times, Java sources, TWS, Control-M, Automic
XINFO loads the result into a database
XINFO has dialogs to query and visualize the data

6. Using XINFO
A major part of daily work consists of gathering up information. XINFO enables you to access that information. Some typical questions are:
Which jobs use dataset 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? …

7. Select EXEC Statements …
How to work with XINFO
e.g. which jobs are using a program?
Select EXEC Statements …

26. XINFO Source Scanner
XINFO’s source scanner are analysing program source code to deliver the following information:
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

27. XINFO Source Scanner
Following data can be input to the source scanners:
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

28. XINFO Program Calls
In addition to language specific data (COPY, variables) XINFO offers “multi language call analysis”
Input are the results of the individual scanners
The results are three tables (Calls, File- and DB2-Access)
Including nested calls
Program 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

47. Summary
XINFO is an information and documentation system for production and development.
XINFO shows you:
How Batch, CICS and DB2 programs are used
When programs are used
Which resources where used
Which databases and tables are used
Which source-code, includes, sub programs, methods etc. are used
XINFO helps you while:
Fixing problems
Doing impact analysis
Estimating projects

48. Available Language Scanners
