2. 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.
