Introduction to the new mainframe
Autonomic Computing Principles
The self-configuring, self-healing, self-optimizing, and self-protecting
technologies of operating environments and systems.
Seamless integration and
distribution of resources
by the operating system
Automatically measure
and tune resources to
improve performance
and usage
SelfConfiguring
SelfHealing
SelfOptimizing
SelfProtecting
Instant detection,
diagnosis and
reaction to
system
disruptions
Anticipate,
detect, identify and
protect against attacks

Introduction to the new mainframe
z/OS Implementation of autonomic computing: Self-Healing
-Repair - as in the Error Correction Code (ECC)
-IBM System z Hardware has spare units on many components. This is
called N+1
• Use of spare PUs
• Use of spare memory chips
• I/O has multipath access
-Concurrent updates
-System Software
• Data Replication
 Coupling Facility Structure
 Synchronous copy
• Automation engines
• Virtualization
• Health Checking

Introduction to the new mainframe
Self-Configuring
• msys for setup simplifies the
management tasks for z/OS software
setup.
• z/OS Wizards are Web-based dialogs
that assist in z/OS customization.
• Capacity upgrade CPU provides
instant access to additional
processors or servers, memory, I/O.
• Customer-initiated upgrade.
• Automatic hardware
detection/configuration.
• Automatic communication
configuration.

Introduction to the new mainframe
Self-Protecting
• LPAR, Certifications FIPS, I40-1
Level 4, EAL4, ZKA, ICSA Labs
1.0A
• Intrusion detection IDS, PKI
• Hardware cryptographic adapters
• Digital certificates providing
identity authentication
• SSL and TLS (manages Internet
transmission security), Kerberos
(authenticates requests for
service in a network), VPN,
encryption
• Tivoli Policy Director
• LDAP (Lightweight Directory
Access Protocol) -aids in the
location of network resources

Introduction to the new mainframe
Self-Optimizing
• Intelligent Resource Director
(IRD)
 allows dynamic resource allocation
on servers
• Dynamic LPAR
 WLM LPAR extensions for Linux
• Parallel Sysplex Extensions
 Sysplex Distributor
 CP Coupling
• BIND9 DNS-DNS BIND Version
9.0 on z/OS
• z/OS workload manager
 CPU, memory, I/O, TCP/IP QOS,
Web request management, and
batch initiator balancing

Summary
The New Mainframe:
•
•
•
•
is autonomic computing
Self-healing, self-configuring, self-optimizing and self-protecting
Autonomlc Computing framework is needed
Touchpoints are needed in the framework. Touchpoints
represent the management interfaces for the things that are
managed.
• Autonomic Computing makes the IBM System z the most
reliable mainframe.
