Pain Points To Solve in the Cloud

•  SoWware management (patching) •  Maintaining up>me and availability

•  Maintaining dependent databases

•  Performance tuning and diagnosis

• …

Why? -‐ Because They Are “Money Pits”

Oracle Rapid Home Provisioning (RHP) So8ware management for the Cloud

1.  Eliminate the need to patch individual databases

2.  Update any number of databases with a single command

3.  Ensure standardiza>on through gold image lineage

<Loosely coupled>

>Tightly coupled<

•  Use Cases 1.  Consistent Management:

•  Apps & DBs in one cluster –  Only use case with 12.1

–  Outlook for 12.2: •  Leaf Nodes hos>ng DBs for (In-‐Memory) Reader Farm –  Performance Op>miza>on for read services in cluster •  E.g. (OLTP) updates on HUB, instantaneous real >me repor>ng on Leaf Nodes

–  Recovery Op>miza>on –  Further op>miza>on in DWH

•  Architecture –  Leaf Nodes

•  Act as compute nodes •  Depend on HUB nodes •  Do not require direct disk access

•  U>lize a different heartbeat mechanism

•  Do not perform writes –  No DML / updates / inserts

•  Thus, no Distributed Lock Management (DLM) required

Improving Availability on Architecture Level

12

•  Use Cases 1.  Non-‐shared disk clusters

•  Client Clusters don’t require their own shared disk access –  Used for applica>on hos>ng

•  Only use case in 12.1.0.2

2.  GI-‐version independent database clusters – Minimum DB version 12c

•  Use case requires 12.2 GI

3.  Highly scalable & flexible

•  Architecture –  Client Clusters

•  U>lize (a) central cluster(s) (ideally) for shared services –  E.g. Storage Server

•  Cost efficiency due to using network connec>ons instead of FC / SAN network

•  Represent independent clusters that can be scaled horizontally and ver>cally

•  CC can be deployed by means of instan>a>on –  VM-‐based, in cloud

•  Make use of RHP

ACFS and a Simple and Free of Charge Approach to Managing Test & Dev Oracle Database Environments

The gDBclone sample script takes databases from any source and duplicates them on the Test & Dev cluster using ACFS snapshots to create space efficient copies.

gDBclone automa>cally converts databases from any type to any type; quickly test your applica>on on a RAC test

database using your SI database produc>on data.
