History, and why System Automation
Disaster recovery;
Security and reliability for the Mainframe environment;
GDPS - From 45 to 9 seconds;
But...and the automation?
Management. Should we maintain two automation softwares?
The legacy...thirty years and the SGM;
SGM must stay.
How can we do that?
Resources and Events.
Planning
Move Groups?
We need an interface
with Control-M.
Tasks and routines
Phases
1- z/OS and Storage;
2- Databases and Message Queue (MQ Series);
3- File transfer, network and security;
4- CICS and Substations;
5- GRI (Transaction manager)
Validation. How do we know that it worked?
Tasks and strategy
Education;
Training;
Teamwork;
Repeat.
Tasks and culture
72 Systems
2.492 applications
727 application groups
Tasks numbers
CA solve utilization;
• 30 years of legacy automation.
Lack of documentation;
SGM (Mainframe Management System).
CA solve automation environment
Integrating Netview/SA And SGM
SGM overview;
TCP/IP server.
Extract and document ;
Consolidation and conversion;
Duplicated activation;
CA Solve Deactivation.
Migration process summary
Extract and Document NCL script to extract and to document traps.
NCL script to extract and to document NCL scripts;
• CSV file
7,507 traps
779 NCLs
72 timers
• NCLs called directly from traps and timers
o 22% Active Traps
o 30% NCLs
Consolidation and Conversion
NCL conversion
o Script REXX to convert NCL script to REXX Netview
o Output: number of scripts
o CA SOLVE traps conversion
o VBs script using CA SOLVE traps CSV file as input
Enterprise traps
Duplicated Activation
Netview/SA automation activation
• Traps were primarily included in INGMSGU1 Netview/SA AT
• Threshold challenge
o REXX scritp to simulate the CA SOLVE threshold behavior
Debug and test
• REXX coded with exceptions (CONDITION TRAPS)
Timers implementation
Full activation
• No rollbacks
• No incidents
Moving traps to the System Automation PDB
CA Solve Deactivation
Major Challenges
Enterprise Automation Policy
Policy management
SDF Focal point
CA solve NCL variable structure
• VarTable (primary key and sort)/ INGRDS
CA solve threshold
• REXX threshold
CA solve "autotasks“
• CA Solve WAIT command migrated to
Netview AFTER command
