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

Database (DB2, ORACLE or MS-SQL) Technical Overview z/OS JCL Scanner SMF Scanner JCL SMF z/OS, UNIX, Windows Scheduler Schedule Scanner UNIX, Windows Filesystem File Content Scanner PC Client zOS, UNIX or Windows XINFO Database (DB2, ORACLE or MS-SQL)

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? …

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

How to work with XINFO 2) Specify program

How to work with XINFO 3) The result

Display more information 2) Select e.g. “Run Cycles + Jobs” 1) Right mouse click...

Show Scheduling Data Looks like a daily run 3) The result

When did the job actually run? Show History When did the job actually run?

Show History Returncode Start time, End time Jobname Duration, CPU-Time etc.

Show Dependencies The job netplan shows all preds and succs Netplan for Job “DB2COB2”

Show Dependencies Job netplans are available for most schedulers, e.g. TWS, CA7, and Control-M

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

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

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

Which programs are called by DSN8CC0 ? Program Calls Which programs are called by DSN8CC0 ?

This table shows all called modules on all levels! Program Calls This table shows all called modules on all levels!

IMS, PSB and DBD Information XINFO IMS shows which jobs and/or transactions are using a PSB Content of IMS DB definitions, all segments, fields etc.

Which methods are defined in class “Action”? Java Scanner Which methods are defined in class “Action”?

Java Methods Method’s detailed view including attributes and parameters

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

Available Language Scanners XINFO supports following languages: Assembler C COBOL Easytrieve Java Natural PL/1
