2. Design and implement your own self service Enabled Private cloud with Oracle Em12c

IOUG presentation and virtual session: session #464, Track: Cloud Computing
April 14, Tuesday 2:00-3:00pm| Room: Palm D
Abstract:: Today when IT organizations plan to deploy Oracle database and applications in cloud, they may look at either using Oracle public cloud service or building their own private cloud. For those who would prefer to building and hosting their own private cloud, there are a quite few Oracle technologies that are designed for this purpose. This session will discuss some of these technologies and methodologies that Oracle used to build the Oracle public cloud: Oracle EM12c cloud management, self-service portal and Oracle Virtual Assemble Builder (OVAB). Using a case study as an example, this session will show how to design and build your private cloud with these technologies and to show how to implement the important cloud service: application self-service provisioning which is featured in Oracle public cloud.

4. Implementing oracle database 12c heat map and automatic database optimization for database storage performance and cost
IOUG presentation and virtual session: session #464, Track: Cloud Computing
April 15, Wednesday 3:15-4:15pm | Room: Palm A

Abstract: While SSD (Solid State drive) based storage significantly improves the database performance by removing the storage IO bottlenecks, the cost of SSDs is still much higher than ones of regular spinning disks. As a cost effective way to leverage SSDs performance, the Storage tiering method stores those active data in high performance SSD storage and store those less or inactive data in low speed conventional spinning storage. While the store tiering methods is usually implemented on the storage level and setup by the storage admin, Oracle 12c Heat Map and Automatic Data Optimization (ADO) together called Information lifecycle Management (ILM) provide a great way for DBAs to automate the storage tiering for database segments on database level . This session will show the steps and method by which DBAs can use to implement these Oracle 12c features to automate the compression of database segments as well as movement of them to another tier storage based on the usage of the data.

Why can’t I connect to my pluggable database?   Leave a comment

This afternoon one of my colleagues was having trouble connecting his database. He got the following error when he

tried to connect the application to the database:

ERROR:
ORA-01033: ORACLE initialization or shutdown in progress
Process ID: 0
Session ID: 0 Serial number: 0

He logged to the database server host and found that the database instance was up and he was able to connect to the database instance :

SQL> connect system/password
Connected.

But when he tried to connect to the application user  in a PDB:

[oracle@inmem2 ~]$ sqlplus  user1/user1pwd@app1_pdb

SQL*Plus: Release 12.1.0.2.0 Production on Mon Sep 15 16:48:13 2014

Copyright (c) 1982, 2014, Oracle.  All rights reserved.

ERROR:
ORA-01033: ORACLE initialization or shutdown in progress
Process ID: 0
Session ID: 0 Serial number: 0

Here is the troubleshooting part that I did:

check if the PDB is up:

sqlplus  / as sysdba

Connected to:
Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 – 64bit Production
With the Partitioning, Real Application Clusters, Automatic Storage Management, OLAP,
Advanced Analytics and Real Application Testing options

SQL> select NAME, OPEN_MODE FROM V$PDBS;

NAME                           OPEN_MODE
—————————— ———-
PDB$SEED                       READ ONLY
APP1_PDB                      MOUNTED

So the APP1_PDB is only mounted not open although the instance is up and the container CDB is open.

So we need to open the PDB:

SQL> alter PLUGGABLE  DATABASE APP1_PDB open;

Pluggable database altered.

check the PDB open status:

SQL> select NAME, OPEN_MODE FROM V$PDBS;

NAME                           OPEN_MODE
—————————— ———-
PDB$SEED                       READ ONLY
APP1_PDB                      READ WRITE

Then he was able to login to the PDB:

SQL> connect user1/user1pwd@app1_pdb
Connected.

My Presentations at Oracle Openworld 2014   Leave a comment

I will be presenting or co-presenting the following sessions at Oracle OpenWorld 2014. This marks my 9th consecutive Oracle Openworld conferences that I have presented. From 2006-2013, I have presented 22 technical sessions or panels at 8 Oracle OpenWorld conferences.

1. Session #ID: UGF9244, Architect Your Data Center Infrastructure from Scratch,  Sunday, Sept 28, 10:00am-10:45am,    – Moscone South – 308

Abstract: The experts in this session are challenged to put together a greenfield design/architecture that could provide the storage, server, and network services for a small to midsize manufacturing company. These experts are then presented with a few business challenges, and the attendees will see how their architecture changes, grows, or contracts to meet these needs. The presentation reveals the difference between vendor hype and the reality of day-to-day usage of these services and discusses how changing trends in technology do or do not fit well into changing business needs. You will leave the session with an understanding of the choices that go into picking a infrastructure service, including storage, backup, servers, and even operating systems.

2. Session ID: UGF3431: Implement and Manage IaaS and a Self-Service Portal with Oracle Enterprise Manager 12c
(IOUG Sunday session), Sunday, Sept 28, 12:00am-12:45am Moscone South – 307 

Abstract: In Infrastructure as a Service (IaaS) cloud model, users can request the infrastructure for applications through the Self Service Portal. This session will focus on how to implement such a Iaas Self-Service with Oracle Enterprise Manager (EM) 12c and Oracle VM. This session will cover the IaaS cloud architecture; creation of VM templates/ assemblies using Virtual Assemble Builder (OVAB), and how to setup the Self-Service deployment mode with Oracle VM templates and virtual assemblies. You will learn the configuration of the entire stack of this infrastructure cloud built on Dell platform and how to use EM12c to manage the entire stack of the cloud architecture including hardware through Oracle EM12c’s Dell Dell OpenManage plug-in.

3. Session ID: CON5433: Leveraging New Oracle Database 12c Features to Reduce Storage Costs
OOW weekday section, Thursday, OCT 9, 9:30am-10:15am, Moscone South – 310 

Abstract: Advances in flash storage are driving ever-increasing performance. And while the price per GB continues to decrease, the absolute cost of top-tier storage offerings is on the rise. One way to combat the high cost of flash storage is to tier data across multiple types of disks to leverage the cost and capacity of conventional spinning disks. This session shows you how to reduce your storage costs without compromising performance, through automatic tiering of your data with two new Oracle Database 12c features: Heat Map and Automatic Data Optimization.
