1 Data Center Management Systems The Expert JCL Manager - JED The Future of Automated JCL Management JED Highlights:(Partial list) The JED Process Operating Environments Supported JED Features and Functions JED Generated Error Messages The Future of Automated JCL Management JED is a fully automated JCL management solution for today's z/os data centers providing JCL validation, standards enforcement, reformatting, and syntax checking. JCL maintenance, conversions and tuning are now possible --- automatically! Robust, yet simple to use, JED provides a flexible, automated way to address the labor-intensive tasks associated with the JCL change lifecycle. JED significantly improves operations and production control environments, resulting in improved SLAs. JED has been designed from the ground up to be JCL-intelligent. Management and control of JCL components in the change lifecycle can be fully automated with the DCMS CCS (Change Control System) product or other automated code deployment tools. Used this way within the JCL change lifecycle or as a stand-alone tool, JED simplifies JCL management, resulting in improved productivity for the entire Information Systems department, including Applications Programming, Operations, Production Control and Systems Programming. When customization is desired, it is not necessary to learn a new programming language or understand the coding and setup of unfamiliar control card formats. JED provides its benefits using an intuitive, high-level user interface. JED Highlights:(Partial list) Complete JCL validation of basic syntax, required parameters and site standards Customized JCL validation rules One-time analysis and mass conversions Easily and accurately maintain JCL for execution in multiple environments JED Remote Server Facility validates JCL for execution on a different LPAR/Image than the one on which the JCL resides Validate SMS classes and requirements Intelligent online Library Search Facility concurrently searches multiple libraries for combinations of JCL statements containing values that match JCL-specific search criteria Validates logical execution processing (EXEC-COND, IF/THEN/ELSE), providing Return-Code simulation by jobstep Validates the execution PARM and SYSIN control statements for all standard IBM utilities Enforces dataset naming standards Reformats JCL members, procs and statements to site standards for keyword order and alignment Provides reformatting options by statement type Optionally re-sequences jobstep names Optionally reformats of instream IDCAMS SYSIN statements Scheduler Interface - enables automated scheduler users to verify how their scheduler will resolve its variables and/or conditional statements within a jobstream at execution time. Single pass processing --- one invocation of JED validates and re-formats JCL

2 Other uses for JED Maintaining JCL for multiple environments Management of vendor-supplied JCL Data center consolidations Production-to-test JCL conversion for application testing Test-to-production JCL conversion Critical path validation at hot site Convert in-stream control statements to PDS members Conversion or enforcement of SMS rules Optimize blocking characteristics Logical processing validation Standards enforcement based on application name or environment The JED Process JED can be used in 3 ways: o Interactively - As an edit macro during an ISPF Edit session. Any error message are shown interspersed within the displayed JCL lines. o Foreground Within an ISPF application. JED provides an intuitive interface for virtually instant results. o Background - As a batch job to process larger quantities of JCL JED can be interfaced with your automated job scheduler, code deployment product, security and tape management software. All product features, functions and interfaces can be tailored by the JED administrator. Most common JCL validation and conversion tasks are already automated and can be activated by toggling an option presented on an online screen. Over 300 options are available.

10 Interface points: Exit point before open of dynamically allocated dataset (PARMLIB,PGMLIB) Exit point to interface with tape management system to verify tape datasets Exit point to modify JCL statements before they are processed Exit points to set values for CONTROL-M, ZEKE and JOBTRAC variables Exit point to permit modification or suppression of messages Exit point after JCL statement is read Exit point before non-jcl statement is written Exit point before termination Exits can be loaded from non-authorized library even when running APF-authorized JED Generated Error Messages "IEFC" messages. JED utilizes the OS JCL Converter component of z/os to perform a portion of the syntax check of the JCL. JED detects all JCL syntax errors that z/os detects. "IDC" messages. JED uses a simulation option of IDCAMS to verify IDCAMS SYSIN data, so some messages are generated by IDCAMS. "JED" messages JED generates hundreds of messages internally as issues are encountered.
