The Natural Life of a Database is Growth…

•Capability to store data on premise

•Ability to provide environments for continuous delivery development.

•Consistent Environments provided to development.

•Ability to provide it faster and more effectively.

•New Architecture based on Micro Services, Big Data Store, Text Search and database technology.


Actual Hybrid Cloning Steps



A Clone is Just an EM12c Job



Clone is Available for Use!



Even a SnapClone Can Be Managed Like A Full Database..

Inspect “Datafiles”, all aspects of clone just as you would a full database copy.



The Challenge •Slow EM Page Response

•No Data Results to Screen

•Slow Refresh of Data Upon Request

•Job Delays

•Time outs on Database Creation to the Cloud

•Access to the Cloud is Slow



What are We Waiting for?

CPU and some IO is expected, but Network is the new wait issue in Cloud Databases…



How Cloning to the Cloud Works



Layers and Firewalls



What You’ve Implemented to Manage the Cloud



What is Sharding?



Where Performance Information Is…

Setup Manage Cloud Control Health Overview

OMS and Repository Monitoring Page Performance



Overall Page Performance


OMS and Repository Monitoring Page Performance


Network Wait Increase with Cloud



Inspecting Cloud Page Waits


OMS Repository Monitoring Page Performance


Database, Java, Agent or NETWORK?


For Cloud, network waits have been experienced due to firewall, DNS resolution and network misconfigurations. Inspecting waits via the Page Performance is important!


SQL and Plan

SQL from Page

Plans

Compare to awrsqrpt.sql

(aka sql_id specific awr)



Job Run

Not to be confused with user sessions


Load Balancers



Why a Load Balancer?

Load Balancer setup and configuration

– Users require session affinity to a particular OMS

This allows for new connections to perform Round-Robin vs. Most Requested which is less efficient.

Allows for simpler scaling for environments to support future growth.



This is your pain point as a DBA- network waits due to misconfigurations, DNS resolution failures and other network features that may impact successful connectivity. By removing these waits and implementing HA, we create a continual service and high performing cloud environment.


High Availability to the Cloud

Ability to Associate Multiple Gateways with Agents

First Gateway becomes “Primary” Gateway, Subsequent become Secondary Gateways.

If the Primary becomes Unavailable, one of the Secondary's Takes over as the Primary by Proxy. If the Secondary become Unavailable, Next Secondary takes over and so on, so forth.



Cloud Performance Achieved!



Using the Access Log

$OMS_HOME/EMGC_OMS1/access.log

•Tracks each login, along with app/module logged in from:

Use NSLookup to locate workstation name.



In Summary…

•Single Pane of Glass Management via Enterprise Manager

•Great DBaaS with Multi-tenant cloning, thin clone and other great features.

•Simple management like standard on-premise cloning.

•Ability to Investigate Performance Issues Easily from Cloud Control

•Powerful, secure and stable management of ALL via a single pane of glass.
