Automated Elasticity for Dynamic Clusters

• Administration APIs for Dynamic Clusters

• Start/stop a specified number of servers

• Expand/shrink the size of the cluster

• Manage server lifecycle, quiescence

• Simple/automated scale up/down or tune

• Rules-based decisions based on capacity, demand or schedule

• Watches, Notifications become Policies, Actions

• Policies: SmartRules, Calendar-based policies

• Actions: scaleUp, scaleDown, REST, script

• Peak Loads, Geographic Patterns, Adding Partitions, Batch Processing, Rebalancing

Microcontainers

• Enable application encapsulation and portability

– Make it easy to move an application from cluster to cluster, domain to domain, on-premises to cloud

– Isolated runtime, administration, security, data

– Immutability and flexibility

– Ultra light weight for fast startup, disposability

Platform as a Service

• Enable density by enabling domain sharing: consolidate at the domain level

– Make it easy to deploy applications from many groups into the same WebLogic infrastructure

– Share WebLogic infrastructure and underlying resources

– Isolated management

• WebLogic Administrators manage the infrastructure

• Partition administrators manage deployments, related resources

– Isolated runtime • Security realm per “tenant”

• Work managers/resource consumption management

Software as a Service

• Enable density by enabling multiple SaaS application instances in a consolidated domain

– Make it easy to deploy additional instances of an application

– Share WebLogic infrastructure and underlying resources:

– Tailor application instance to tenant:

• Virtual Target (addresses, etc.)

• Database – pluggable database

• Other runtime resources (e.g., JMS)

– Isolated runtime • security realm, virtual target, database, work

managers/resource consumption management

• Assumption: known and trusted applications

Three Categories of Use Cases


Multitenancy in WebLogic

• Enable high density by enabling domain sharing: consolidate/virtualize at the domain level

– Domain partitions

– Virtual targets

– Resource groups

– Resource group templates

• Enable domain sharing with isolation

– Administration, security, traffic/data, runtime

• Enable agility/devops with pluggable partitions

– Application portability

– Ultra-light container-like service packaging

Oracle WebLogic Server 12.2.1 Multitenancy Concepts

• Key new concept is the domain partition

• Apps and resources deployed for each partition

– No application changes required

• Partitions are isolated

• WebLogic infrastructure shared among partitions

• Partitions can span clusters

• Partitions can be started/stopped independently

• Partitions can be “exported” and “imported”

• Partitions support live migration

Runtime Isolation

• JDK and WebLogic partnership

• Resource Consumption Management (RCM)

• Heap, CPU, threads, requests…

Administrative Isolation

• Admin roles, lifecycle, troubleshooting

Security/Identity Isolation

• Realm, users per partition

Traffic/Data Isolation

• Dedicated JNDI, segregated data

• Dedicated and shared Coherence caches

Isolation for Pluggable Partitions Independence and Autonomy for Microcontainers

Managed Server/Cluster

• FMW Control – Primary Multitenancy Console

– Recommended for single- and multi-partition domains

– Usage with “restricted JRF” recommended

• JRF enabled on admin server, DMS only on managed servers

• No database configuration required

• WebLogic Console

– Recommended for single-partition domains only

• Enterprise Manager Cloud Control 13.1

– Supports WebLogic 12.2.1, partition monitoring/lifecycle

• WLST online, JMX, REST

– Config Wizard, WLST offline not yet partition-aware

• Partition export/import tool

Adopt Service-Based Architectures: Increase Agility


Resource Consumption Managers

• Deep integration between WebLogic Server and the Oracle JDK

• Prevents resource hogging, protects applications in a shared JVM

• Managed resources

– Retained heap, CPU time, open file descriptors

• Triggerable actions – Notify – inform administrator that a threshold has been crossed

– Slow – reduce partition’s ability to consume resources

– Fail – reject requests for the resource (file descriptors only)

– Stop – initiate the shut down sequence for the offending partition

• “Boundaries” and Fair Share usage patterns

Multitenancy in WebLogic 12.2.1

• Agility/devops with lightweight pluggable partitions – Ultra-light container-like service packaging

• High density with domain and JVM sharing – Consolidate/virtualize within domains and

JVMs

• Isolation between microcontainers – Runtime, administration, security, data

WebLogic Multitenant Partition Portability

• Move running partitions and resource groups from one cluster to another without impacting application users.

• Eliminate application downtime for planned events

– Capacity balancing, patching, upgrades, imminent failure, …

• Current granularity and scope: – Resource group – Clusters within a domain – Webapps – Requires OTD

• Future – All application types and protocols, including T3, RMI, JMS – Migration across domains

• Feature only used with the Continuous Availability license + Multitenant license.

Live Migration

Cluster 1 Partition 1

Cluster 2 Partition 1


WebLogic Automated Cross Domain Transaction Recovery Automatic Transaction Recovery

• Recovery of XA transactions of a crashed domain, or entire site by server(s) running in a different domain or different site.

– Automatic recovery after failure

– Transaction recovery in active-active application infrastructure architectures

– Requires JDBC TLog, or LLR, or No Transaction TLog write (No Tlog) feature

– Relies on TLogs being replicated by database replication technology

Coherence Federated Caching Local Data access in Multi-Datacenter Solutions • Distribute data grid updates

• Multiple distribution strategies

– Active/Passive • Read-only operations or off-site backup in the

passive site.

– Active/Active • Cached data is always replicated between

clusters. Applications in different sites have access to a local cluster instance.

– Hub & Spoke • The hub cluster can only send data and spoke

clusters can only receive data. Require multiple geographically dispersed copies of a cluster.
