IBM z/OS, Automation tools, ITIL.

Success Metrics

Automation Coverage: % of manual tasks automated (target: 3050% reduction in toil).

Incident Reduction:
Fewer repetitive incidents due to proactive automation.

Change Compliance: 100% artifact capture for automated changes.

Efficiency Gains:
Measurable reduction in batch window and operator interventions.

Tools & Environment

Languages:

Rexx, CLIST, JCL, optional Python for z/OS.

Roles & Responsibilities

Automation Development & Maintenance

Design and implement automation scripts (Rexx, CLIST, JCL, Ansible for z/OS) for routine operational tasks, health checks, and system recovery.

Develop WTOR confirmation automation for operator commands with validation logic.

Automate batch scheduling workflows in IBM Workload Scheduler (IWS/TWS) and integrate with enterprise orchestration tools.

Create self-healing mechanisms for common issues (e.g., MQ transmit queue backlogs, DB2 log utilization alerts, IMS region restarts).

Monitoring & Alerting

Build real-time monitoring dashboards for system health (CPU, DASD, queue depths, buffer pools).

Implement event-driven automation for proactive remediation (e.g., auto-restart channels, clear JES backlog).

Integrate automation with SIEM/SOC tools for security compliance.

Governance & Compliance

Ensure all automation adheres to audit requirements: capture execution logs, approvals, and artifacts.

Maintain version-controlled repositories for scripts and automation frameworks.

Validate automation against SOX/ISO controls and enforce segregation of duties.

Performance & Optimization

Automate capacity checks and performance tuning tasks for DB2, IMS, and CICS regions.

Reduce batch window through job stream optimization and dynamic workload balancing.

Collaboration & Documentation

Work closely with System Programmers, Operations, and Application teams to identify automation opportunities.

Document all automation solutions with runbooks, rollback plans, and audit evidence.

Provide training and knowledge transfer to operations teams.
