Choices for Full JCS or JCS-VI

Billing Frequency

WebLogic (Edition & Version)

WebLogic Cluster size & ‘Shape’ of MS cluster node(s)

(optional) Coherence

(optional) Oracle Traffic Director

(full JCS only) Storage Container

REST APIs

DEMO

What does a small JCS cluster look like?

E.g. 5 VMs: ◦ 1 Traffic Director

◦ 2 WebLogic

◦ 2 Coherence (optional; 3 is more “Coherence-friendly”)

One domain including: ◦ WebLogic & Coherence clusters

◦ Node Managers

◦ FMW Infrastructure, including schema in DB

◦ Demo SSL certificates

◦ An OTD virtual host to the WLS Cluster

A default backup schedule

Tailor the Environment

Set up SSL certificates Changes to Server Start parameters, setUserOverrides.sh

(setDomainEnv.sh) Manage storage Adding further clusters/nodes etc ◦ See “Keeping Your Service Instances Manageable by Oracle Java

Directory structure

ORACLE HOME: /u01/app/oracle/middleware

JDK HOME: /u01/jdk

DOMAIN HOME: /u01/data/domains/<domain-name>

Others: ◦ /u01/data/backup – backup location

◦ /u01/app/oracle/tools – Oracle ‘cloud tooling’

Backup / restore

Backup types ◦ Binaries plus domain configuration

◦ Domain only (aka ‘incremental’)

◦ Database can be included too (creates an RMAN tag in DBCS instance)

Schedule ◦ Weekly full & daily incremental by default

Location and Retention Policy ◦ Held locally for a week, then moved to Storage Service

◦ Retained for 30 days by default

Backups are encrypted (using a key known only to OPC)

Full JCS only

Patching

WebLogic PSUs plus JDKs JCS backs up beforehand and can rollback later (all?) Patches are rolling (if you have load balancer) Each Managed Server is:

1. backed up 2. removed from Traffic Director origin server pool 3. shut down 4. JDK or Oracle Home replaced with a patched image 5. restarted

6. added back to Traffic Director pool

Full JCS only

JCS Management

Provisioning/managing non-trivial JCS platforms will mostly be using REST APIs ◦ Everything in OPC console can be done via REST APIs

◦ REST tools (browser plug-ins like Postman or RESTClient, curl etc) and JSON format are quick/easy to learn

All your existing tools/techniques still work with JCS ◦ Connecting to Node Manager

◦ Java Mission Control & other JVM diagnostics tools

◦ Enterprise Manager 12c (Hybrid Cloud Agent etc)

Quick Tips

Naming conventions Key management The Oracle product filesystems are overwritten

(swapped) during patching – don’t put any of your own files in there! ◦ e.g. EM agent

Set up disk free space alerts

How do you provision today?

Manually?

Automated s/w only?

Automated s/w + initial

domain? Fully

automated?

Recognize this?

Better than nothing,

but this is like typing in code every time you

want to run a program!

… use one of these instead!

How do you deploy today?

Manually?

Scripts ?

Continuous Integration

for test?

Fully automated

CI / SD?

Deployment

There are LOTS of tools to help (including previous tools) – pick something!

Rolling patching Done

by PaaS

Post-cloud influences & time savers

Can your custom apps be replaced by SaaS ?

Oracle PaaS Admin. Tasks for your Org.

Platform Design ◦ Sizing / costing ◦ Naming conventions (as important as ever) ◦ Capacity planning

Operations ◦ Application Deployment ◦ Performance Assurance and Tuning ◦ Monitoring and management

PaaS is intended to be used by administrators, not power users Someone still has to be responsible for mission-critical systems

Consumption

Someone needs to monitor consumption As for all cloud services… ◦ It’s (too?!) easy to spin up new environments ◦ Do they all need to be running?

Consider monthly vs hourly ◦ Hourly is +25% but if instance only used

8h/day then 42% of monthly cost

Consider JCS vs JCS-VI

What does this mean for your role as

Middleware Administrator?

Middleware administrators don’t spend that much time on installing software / creating domains

Highest value work is rolling out new applications/features & fixing performance of existing ones

If we looked further down the stack expect a different picture e.g. sys admins, virtualization admins, storage admins

What does the Business want?

• Backup

• High availability & DR

• Environments

• Upgrades & patching

• Monitoring

• Have what they want

• New func. as soon as $

• Justifiable cost

• Compliance

• “on” like Facebook

Summary

Full JCS is here & viable for many types of workload

JCS/JCS-VI gives you power/flexibility of WebLogic including most of the control you are used to

You will be doing far less menial, low-value work – make yourself more valuable!

…but someone still has to be responsible for your Oracle platforms… you!
