Introduction

Journal Analysis and Optimization

• Journaling Uses and Benefits• Understanding Costs and Implications• Ongoing Management and Administration

Journaling Uses and Benefits

• High Availability• Data Warehousing• Commitment Control• Security and Data Auditing• Application Debugging• Troubleshooting

High Availability

• Data Replication Requirements• Additional System(s) Impact• “Real-Time” Replication• Remote Journaling• Increased Network Traffic• Quality Assurance & Testing

Data Warehousing

• “Offloading” Workload• Data Transformation• Moving versus Solving Issues• End-User Queries• SQL Performance Analysis• Duplicate Data – Integrity!

Commitment Control

• Appropriate Journaling Needs• COMMIT and ROLLBACK• Performance Implications• Added Controls & Integrity• Costs versus Benefits• Impact on Data Replication

Security and Data Auditing

• Native File System• Integrated File System• Impact of Temporary Objects• Application - Opens/Closes• Security Audit Journal (QAUDJRN)

• Impact on Object Replication

Application Debugging

• Data Integrity Issues• Application Performance• Adds, Updates, Deletes• Opens, Closes• Temporary Objects• “Real-Time” Information

Troubleshooting

• Application Issues• Systems Management• Performance Analysis• Security Concerns• Disaster Recovery• System Availability Issues

Understanding Costs and Implications

• Performance Implications• Hardware Upgrade Costs• Data Integrity• System Availability• Security Risks• Real-Time Visibility

Performance Implications

• Nightly Processing Window• Month-End Closing Cycle• Interactive Response Time• End-User Query Needs• “Real-Time” Data Replication• DASD, CPU, I/O, Memory…

Hardware Upgrade Costs

• Appropriate Upgrades• Optimization Costs/Benefits• Hardware Costs/Benefits• I/O Bound Systems• Better Systems Management• Simple Application Changes

Data Integrity

• Business Impact Analysis• Difficult to Identify/Solve• End-User Confidence• Performance Implications• End-User Queries• Analysts Time and Effort

System Availability

• Day-to-Day System Uptime• Recovery Time After Failure• Weekly Processing Window• Month-End Downtime• 24x7 System Availability• Proven, True, Hot Backup!

Security Risks

• Basic System Auditing• Data Access and Auditing• Public versus Private Network• Reasonable Security Levels• Proactive versus Reactive• Auditing – Part of Solution

Real-Time Visibility

• A “Real-Time” World• Competitive Advantage• Data Synchronization Wows• Responsive to Customers• Functionality and Accuracy• Truly Integrated Systems

Ongoing Management and Administration

• DASD Requirements• System Backups & Recovery• Appropriate Journaling• Journal Receiver Retention• Error Detection & Recovery• Performance Analysis

DASD Requirements

• Disk Storage Impact• Disk Arm Activity• I/O Bound Systems• Multiple ASPs• Memory Utilization/Faulting• CPU Under-Utilized

System Backups & Recovery

• Resulting Downtime• Reasonable Protections• Performance Analyze Backups• Backup to Disk, Disk to Tape• Multi-threaded Backups• Proven Recovery Procedures

Appropriate Journaling

• 50 to 80 Percent Waste!• Temporary Objects (Native/IFS)• Application Changes• Whole System versus Selective• Entire Data Libraries• Work Files and User Spaces

Journal Receiver Retention

• Reasonable Choices• Analyze Before Deleting• Prevent Transactions• Simple Application Changes• Systems Management Options• Learn from History!

Error Detection & Recovery

• Journaling Omissions• Tested Backup/Recovery• Application/Data Integrity• Security Breaches• System Failures• Proven Recovery Process

Performance Analysis

• Journal Transaction Analysis• Application Optimization• Query & SQL Tuning• Disk Space Management• Disk Activity Monitoring• Performance Improvement!
