HORIZONT 2 XINFO ® 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.

HORIZONT 4 XINFO ® 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:

HORIZONT 24 XINFO ® 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 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 XINFO Program Calls In addition to language specific data (COPY, variables) XINFO offers “multi language call analysis”
