24 What Does it Mean for Production

!  An �Embedded Server� profile is a production instance of the configured Liberty server type ►  Think of zipping up the application, configuration, and server that you just

tested on ►  Application centric – the server is pre-configured for a specific application(s)

!  Deployment options: ►  Unmanaged unzip install… OR ►  Managed ND Job Manager creates �Liberty deployments� by distributing

and unzipping the embedded server package ‒  �Light-touch� ND management (Job Manager): start and stop server

►  Server configuration remains via the same simplified XML config created in the development environment

Simplify restoration of earlier configuration checkpoints and record all configuration updates is security audit log.

!  The Repository Service is consolidated from WVE !  Provides �full� and �delta� checkpoints of the

master configuration repository. !  Simplifies restoration to a previous

configuration state. !  Full checkpoint created manually !  Delta checkpoints, when enabled, are

created automatically in checkpoint repository on every configuration-save

!  New Security Audit event - ADMIN_REPOSITORY_SAVED refers to corresponding delta checkpoint records.

!  The delta checkpoint can be exported to review configuration changes when needed


Sample Audit Record

Health Management

8

!  Automatically detect and handle application health problems ‒  Without requiring administrator time, expertise, or intervention

!  Intelligently handle health issues in a way that will maintain continuous availability

!  Each health policy consists of a condition, one or more actions, and a target set of processes

!  Includes health policies for common application problems !  Customizable health conditions and health actions

Sense and respond to problems before end users suffer an outage

Comprehensive Health Policies

Customizable Health

Actions

Customizable Health

Conditions


Health Management – Health Policies

!  Health policies can be defined for common server health conditions

!  When a health policy's condition is true, corrective action execute automatically or require approval

•  Notify administrator (send email or SNMP trap)

•  Capture diagnostics (generate heap dump, java core)

•  Restart server •  Place server in main mode

!  Excessive response time means you are monitoring what matters most: your customer's experience!

!  Application server restarts are done in a way that prevent outages and service policy violations

!  Each health policy can be in supervise or automatic mode. Supervise mode is like training wheels to allow you to verify that a health policy does what you want before making it automatic.

Helps mitigate common health problems before outages occur

Health Conditions •  Excessive request timeouts: % of timed out requests •  Excessive response time: average response time •  Excessive garbage collection: % of time spent in GCs •  Excessive memory: % of maximum JVM heap size •  Age-based: amount of time server has been running •  Memory leak: JVM heap size after garbage collection •  Storm drain: significant drop in response time •  Workload: total number of requests


Health Management – Custom Health Conditions

Flexibility to determine what an �unhealthy� condition is… !  Custom expressions can be built which use metrics from: •  The On Demand Router, URI return codes •  PMI metrics, MBean operations and attributes •  Examples: hung thread detection, DB connection pool exhaustion or slow down

!  Complex boolean expressions using a mix of operands is supported (AND, OR, NOT)


Dynamic Cluster

! A Dynamic Cluster (DC) is a virtual cluster of servers (typically, WebSphere Application Servers)

! Application server definitions are dynamically created or deleted based upon DC membership rules

! Application server definitions are automatically updated when the server template associated with the DC is updated

! Application servers are started/stopped based upon current application demand and service policies

ODR

WAS Nodes –  Nodeagent –  Application Servers

Deployment Manager administration

start another Application Server in the DC

Master Configuration Dynamic Clusters

APC Controller

Example Dynamic Cluster

"  Keep at least one server running at all times

"  Don't start more than 4 servers

"  Don't start more than 2 servers on the same Node


–  Service policies are used to define application service level goals

–  Allow workloads to be classified, prioritized and intelligently routed

–  Enables application performance monitoring

–  Resource adjustments are made if needed to consistently achieve service policies

Service Policies define the relative importance and response time goals of application services;

defined in terms the end user result the customer wishes to achieve

What is a Service Policy?

!  Easily allows an administrator to specify the relative importance of applications and optionally a response time goal. WebSphere then manages your applications according to this policy.


!  Requests are prioritized and routed based upon administrator defined rules •  Flexible policy-based routing and control

!  On Demand Router (ODR) is the focal point for Intelligent Routing !  A routing tier that’s aware of what’s happening on the application

server tier •  Application server utilization, request performance, etc…

!  Route work to the application server that can do it best !  Provide preference for higher priority requests !  Integrates with Health Management and Dynamic Clustering

Intelligent Routing

Improves business results by ensuring priority is given to business critical applications


On Demand Router Goals

! The ODR works with the health management and dynamic clustering features as the underpinnings for intelligent routing

! Automatic routing without having to update configuration files when you change something in your environment (application, server, node, etc)

! A highly scalable routing tier

! Ease of management

! A routing tier that is aware of what is happening on the application server tier and reacts accordingly

! Flexible policy-based routing to control if, when, and where requests are routed

! A highly available deployment manager

Automatic, Scalable, Application-aware Intelligent Routing
