System i5: Maximizing Performance and Availability

Transcription

1 System i5: Maximizing Performance and Availability Amy Anderson Rochester Executive Briefing Center

2 Agenda Historical perspective on performance and availability management Performance tools at your fingertips Availability tools you already bought

3 Evolution of Application Design ILE Modular ILE COBOL, RPG III & CL Applications COBOL, RPG IV & CL Applications Logic Display Print Data e-output Java Bean ILE *SRVPGM Java Bean GUI 5250 Web DB2 UDB Triggers DB2 UDB Stored Procedures DB2 UDB Constraints

4 i5/os data access has evolved too One Database Management System with multiple interfaces Command Language (CL) Structured Query Language (SQL) Embedded ODBC JDBC CLI CRTPF High Level Language Native I/O DB2 DB File (PF) object CREATE TABLE SELECT... FROM...

5 Traditionally, the system admin managed availability

6 Application Models Who owns availability? Who owns performance? Web Web Centric Web Traditional Host centric Client / Server Collaborative n-tier Thin client Middle tier (App servers) Back end (DB server) Integration connectors

7 Performance tools at your fingertips

8 The Core Performance Management Tools High-Level Reports Basic Analysis Long-term Planning PM iseries Detailed Reports Intermediate Analysis Green Screen & GUI Performance Tools Graphical Performance Monitor Notify When Performance Exceeds Normal Thresholds iseries Navigator Monitors Collection Services (i5/os) Performance Data Collection Response Time Database Middleware I/O Service Time, utilization, throughput Workload activity Transactions Comm/Network i5/os iseries

9 Advanced Performance Management Tools Performance Explorer Reports Performance Tools idoctor for iseries Analysis Tools Real-time Advanced Job Analysis Java Heap Analysis & Object Profiling View/Analyze PEX Trace Events Performance Data Collection for jobs, threads, programs, system events Performance Explorer (i5/os) idoctor for iseries Collector Performance Data Collection for jobs, threads, programs Response Time Database Middleware I/O Service Time, utilization, throughput Workload activity Transactions Comm/Network i5/os iseries

13 Enterprise Workload Manager Automated Workload Management for Distributed Heterogeneous Infrastructures Manage business process service levels Improve utilization of IT resources

14 Availability tools you already bought

15 Virtualization Engine Console

16 IBM Director 5.1 Provides Centralized Management Across Heterogeneous Servers Create Monitors Collect inventory on hardware and software resources Event Action Plans: Trap for errors at system or application level Alert via , pager, phone, or instant message Take default actions

17 Single server IASPs provide many features System A Vary On System ASP Independent ASP Availability Vary off before controlled IPL Isolate applications and data from each other Database design Create test and development databases that are identical to production Create database instances similar to UNIX environments

18 Switchable IASP lets you switch disk between two systems System A System B System ASP Independent ASP
