HORIZONT 1 XINFO ® The IT Information System HORIZONT Software for Datacenters Garmischer Str. 8 D München Tel ++49(0)89 / XINFO Scheduler migration support

HORIZONT 2 XINFO ® Scheduler migration support Review the relevant interfaces Demonstrate some interesting aspects Show several example queries This presentation shows how XINFO supports a project team during conversion from one scheduling system to another. Contents:

HORIZONT 3 XINFO ® Scheduler Interfaces APM (HS5000) A-Auto Bagjas CA-7 CA-Scheduler Control-M (z/OS and distributed) TWS for z/OS (OPC) and TWS distributed UC4 Zeke Following scheduling systems are integrated in XINFO:

HORIZONT 4 XINFO ® Resulting Data The XINFO scanner reads job definitions, prepares the data (flags, timestamps, etc.) and groups it in logical parts: Job definitions, descriptions, options, etc. Scheduling parameters, rules, calendar etc. Dependencies, predecessors, successors Resource usage Special functions like Recovery, JCL-Variable etc.

HORIZONT 5 XINFO ® Scheduler flowcharts Graphical view of the job dependencies

HORIZONT 6 XINFO ® Additional useful interfaces JCL Scanner to find -Special program calls -Scheduler Utilities -Dataset usage -Scheduler specific JCL constructs -Scheduler Variables SMF Scanner -To check jobs last run, durations etc. XINFO provide more interfaces:

HORIZONT 7 XINFO ® Analyze the Complexity Every conversion project will begin with an analysis and planning phase: Determine the quantity of defined and obsolete objects (jobs, schedules, calendars, resources etc.) Which special features are being used and how often? (resource control, return code handling, dummy-jobs, variables, recovery etc.) Find out manual interactions or dependencies Which interfaces are installed and how do these work (ticket generation, system automation etc.)

HORIZONT 8 XINFO ® Analyzing and Planning These figures and information helps you to Estimate the resources needed for the project Check if there are any features that are not available in the new scheduler Check what can be done by a conversion tool Check what can be done or must be done manual Planning the activities and generate a realistic project schedule

HORIZONT 9 XINFO ® Analyzing without XINFO? Standard utilities and scheduler reports are unsuitable to answer all queries It takes a lot of manual work to get the needed information and present it in a useful layout See some query examples in the following slides

HORIZONT 10 XINFO ® How many jobs have been defined? TWS z/OS (OPC) Selection

HORIZONT 11 XINFO ® How many jobs have been defined? Specify selection criteria if needed

HORIZONT 12 XINFO ® How many jobs have been defined? After seconds, get the result Use the GROUP function e.g.… GROUP 1

HORIZONT 13 XINFO ® XINFO Group Function … to get the number of applications… …and how many jobs every application contains STAT 1 The statistic function…

HORIZONT 14 XINFO ® XINFO Statistic Function … gives you -Average jobs/appl. -Sum -Max. -Min. -Number of values

HORIZONT 15 XINFO ® Analyze Scheduling Options Control-M Selection

HORIZONT 16 XINFO ® Analyze Scheduling Options Show all jobs, scheduled by a specific calendar (Calendar non blank)

HORIZONT 17 XINFO ® Analyze Scheduling Options GROUP 2

HORIZONT 18 XINFO ® Analyze Scheduling Options Grouped by calendar name

HORIZONT 19 XINFO ® Analyze Scheduling Options Jobs with maxwait > 2

HORIZONT 20 XINFO ® Analyze Scheduling Options

HORIZONT 21 XINFO ® Look for “dummy-jobs” CA-7 Selection

HORIZONT 22 XINFO ® Look for “dummy-jobs” EXEC = N

HORIZONT 23 XINFO ® Look for “dummy-jobs” In TWS it would result in a Job on a “dummy-WS”, in Control-M a Job with Memlib = DUMMY, …

HORIZONT 24 XINFO ® Check dependencies You can generate a job to do the query in Batch BATCH

HORIZONT 25 XINFO ® Analyse in batch Specify output DSN

HORIZONT 26 XINFO ® Analyse in batch Run and/or save the job

HORIZONT 27 XINFO ® Analyse in batch And use the result for further processing…

HORIZONT 28 XINFO ® Find scheduling commands in JCL Complete information about JCL - Statements

HORIZONT 29 XINFO ® Find scheduling commands in JCL CA-7 demands

HORIZONT 30 XINFO ® Find scheduling commands in JCL CA-7 demands found in SYSIN member

HORIZONT 31 XINFO ® Job run history The SMF scanner provides information of job start/end/duration etc. It can be collected for a long period.

HORIZONT 32 XINFO ® Job run history You can create your own SQL, using sub-select, join etc. and execute it in SPUFI or batch. Sometimes you need information based on two XINFO tables, e.g.: all jobs=XXR* that did not run since

HORIZONT 33 XINFO ® Use XINFO in Batch Perform frequently used queries, and process use the result in your own REXX programs Create “to do” lists Compare dependencies between the old and new scheduler definitions Generate new job definitions Check site specific scheduling rules and naming conventions

HORIZONT 34 XINFO ® Use XINFO in Batch Check site specific scheduling rules and conventions, e.g.: Not allowed options (highest RC>8, maxwait=99 etc.) Wrong priority Missing restart documentation (OI, Prose, Doc-Mem, …) Resource missing or wrong Predecessor job not found Dummy start/end operation exist or not Member=jobname, correct jcllib etc.

HORIZONT 35 XINFO ® Graphic flowchart Visualize and compare the dependencies of critical job streams, e.g. together with application developers CA-7 Control-M TWS

HORIZONT 36 XINFO ® Summary XINFO is not a conversion tool, but it helps you to Analyse the complexity Check the conversion results Give required information to anybody Create your own conversion routines, based on XINFO data Suggestion: Install two XINFO: -One for actual information, daily refreshed -One with the frozen status before conversion (Scheduler, JCL and SMF Information).
