Oracle Cloud

The Oracle Cloud Stack
Database
Database Backup
Compute
Storage
Network
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: 43.2s
Weekly: 5m 2.4s
Monthly: 21m 54.9s
Yearly: 4h 22m 58.5s
Like Amazon AWS & Azure

Oracle Cloud Communication (1)
Enterprise Manager
OMS
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_inst
Dummy rdbms : rdbms12102 n/a /u01/app/oracle/product/12.1.0/dbhome_1
DB-instance (N|N) : CLOUD01 open /u01/app/oracle/product/12.1.0/dbhome_1
Listener : LISTENER up /u01/app/oracle/product/12.1.0/dbhome_1
Agent : emagent13c up /u01/app/oracle/product/agent13c/agent_inst
[opc@CLOUD01 ~]$
The Agent ist up and running – example Output from TVD-Basenv Framework
