I Can See! Experiences With Managing DFSMShsm Visually and Automatically Using CA VantageIan ChudleighCA Inc.

August 28th, 2009Session 2436

Abstract

• DFSMShsm has grown in complexity over the years and performs a wider range of tasks than ever. Attend this session to see how users gain visibility into DFSMShsm processes using the CA Vantage Graphical User Interface. See examples of the visual tools that help you decide when to leave DFSMShsm alone, and when to use CA Vantage automation wizards to tailor DFSMShsm processes to meet your requirements.

DFSMShsm Automation

• General Automation• Message Automation

• Real Time Log Intercept or Post Process• Most Common Usage• Specific User Examples

27

General Automation (GOA)• General Principles

• Scheduled, Wizard Driven, Operates On All Objects• Violations Defined By Filters For Flexibility• Comprehensive Response Actions

• JCL, Operator Commands, Emails, Pagers, Problem Tickets, WTO, SNMP, CA Unicenter

• Can Take Multiple Passes With Different Actions

GOA Wizard – Minimizes Coding

Automated Action Example

33

Multiple Phase Automation

34

• Problem Should be Solved • E.g. Apply Same Filters, Record Count = 0• Ensure Data Sources Have Been Refreshed

Message Automation

• Console Messages• DFSMShsm Intercepted In Real Time • DFSMShsm Log Scan• Responses can be any or all of:

• Batch Job• Operator Command• WTO, TSO SEND, E-Mail Message, Unicenter, SNMP• Various Logging Options including SMF

• Can schedule in shifts• Message Parsing and Substitution Capabilities

35

Message Automation Wizard

36

Most Common User Automation

• Selective Migration Of Files Early • Recycle Based on Own Timetable and Criteria• Identifying and Alerting TTOC Issues• Monitor ML1 Pools• Monitor MWE Queue• Controlling Functions such as EXPIREBV, BACKVOL CDS• Dozens Of ARC Message Opportunities

37

Specific User Automation Examples

• RECYCLE – Many Specific Implementations• Recycle tapes with <24% valid data without a previous or

successive volser. An email of the volsers is sent to the Tape Group. A job is submitted which issues HSM Recycle commands and also IEBGENERs the volsers into a GDG. This GDG is then used for input, by another job outside of the script, to locate the slot number each cartridge resides in the Rack

• LARGE Pool Migration• Two-phase Script. Monitors for SGLARGE > 95%. Sends

Migrate commands to DFSMShsm for data sets > 7500 tracks The second phase executes 60 minutes later and will migrate data sets smaller than 7500 tracks if the 95% threshold is still exceeded. Email Notifications sent.

38

More User Examples

• Ensure DFSMShsm Tape Copies• Tape Duplexing with DFSMShsm was recently implemented

and the tape copies are normally created during secondary space management. This script emails a list of tapes that do not have copies.

• Migrate Large GDGs Direct to Tape• At a particular time, migrate large GDGs from a particular

application to tape.• ML1 to ML2 Migration

• Migrates the 50 largest data sets from ML1 to ML2 when the ML1 pool is greater than 90% full

39

User Examples - DFSMShsm Real Time Messages

• ARC0734I RC=37, Redrive large ML1 Migrations to ML2• ARC0352I 40 Tape Limit For DSN• ARC1506E Recall Queue and Coupling Facility• ARC0019I Monitor Cell Pool Shortages• ARC0422I and ARC0425I Tape Copy Return Codes and

Errors
