Oracle Cloud

The Oracle Cloud Stack


Database

Database Backup

Java

IaaS

PaaS

Database


Choose between a single schema or a virtual pre-configured Oracle database, ready-to-use.

Database as a Service

– Dedicated virtual machine

– Also available as virtual image with Oracle software only

– Full root / Oracle Net access

– Oracle cloud tools

Database Schema Service

– 1 11g Schema 5,20, 50 GB storage

– APEX 5 pre-confiugured

Exadata Service

Database as a Service


12.1.0.2 Multitenant

Oracle Linux 6.4

Database Backup


Transparent backup management using RMAN for seamless backup and restore operations.

Backup has to be encrypted locally

Licences for advanced compression and advanced security included

Compute vs. Dedicated Compute


Compute– Shared Compute Zone

– Dedicated Core Capacity: 50 and 100 Cores

– Some Isolation via Resource Management across Tenants but noisy neighbors can impact others

Dedicated Compute– Completely Dedicated Compute Zone

per tenant

– Predictable Performance

– Complete Network Isolation

– Site to Site VPN

– 500, 1000, 1500, 2000 Cores

Service Commitment


Oracle will use commercially reasonable efforts to make Oracle Database Cloud Service available with a Monthly Uptime Percentage of at least

99.95% during any month of the Services Period. SLA level of 99.95 % uptime/availability gives following periods of potential downtime/unavailability:

Daily: 43.2sWeekly: 5m 2.4sMonthly: 21m 54.9sYearly: 4h 22m 58.5s

Like Amazon AWS & Azure

My Cloud DSaaS Instance is up and running

Oracle Cloud Communication (1)


Enterprise ManagerOMS

Hybrid Cloud Gateway(On-Premise Agent)

Hybrid Cloud Gateway(On-Premise Agent)

Hybrid Cloud Agent

Hybrid Cloud Agent

Oracle Cloud Communication (2)


The on-premise OMS communicates with a Hybrid Cloud Agent over SSH

On the Oracle Cloud machine an EMCTL dispatcher is running (Agent Process)

The EMCTL dispatcher forwards communication from the on-premise OMS to the Hybrid Cloud Agent

The EMCTL dispatcher streams the responses from the Hybrid Cloud Agent back to the on-premise OMS via Hybrid Cloud Gateway Proxy


Configuration

Prerequisites


Oracle Enterprise Manager 12.1.0.5 or higher

A Management Agent for the Hybrid Cloud Gateway Agent configuration

Port 22 open on the Oracle Cloud virtual host

Cloud SSH keys for user oracle to create a Named Credential

Hybrid Cloud Gateway Agent


$ emcli register_hybridgateway_agent -hybridgateway_agent_list='solothurn.trivadistraining.com:3872'

Successfully registered list of agents as hybridgateways.

Used as SSH Daemon / Port Forwarding

You have to define at least one local Agent as Hybrid Cloud Gateway Agent

The Hybrid Cloud Gateway Agent is failover ready

The Agent on the OMS host is a perfect candidate

Use emcli from $OMS_HOME/bin

Enterprise Manager Named Credential


A Named Credential has to be created with Public and Private Keys

Agents do not communicate directly with username/password to the cloud

Installing a Hybrid Cloud Agent












Root.sh


[opc@CLOUD01 ~]$ sudo /u01/app/oracle/product/agent13c/agent_13.1.0.0.0/root.sh

Finished product-specific root actions.

/etc exist

Oracle cloud pre-configured user OPC has sudo permissions to execute the root.sh

Server Situation


[opc@CLOUD01 ~]$ sudo su - oracle

TYPE (Cluster|DG) : SID/PROCESS STATUS HOME---------------------------------------------------------------------------

Dummy emagent : emagent13c n/a /u01/app/oracle/product/agent13c/agent_instDummy rdbms : rdbms12102 n/a /u01/app/oracle/product/12.1.0/dbhome_1
