Current Release of database is 10.1.0.5 and the upgrade release should be 10.2.0.4
1. Download the following pre-requisites for Installation.
Software Requirments
10.2.0.2 software on Linux x86
10.2.0.2 companion on Linux x86 CD for ultrasearch
10.2.0.4 patchset Linux x86.
NOTE: No hardware or software level changes may be required for this upgrade at the O/S level.
Steps:
Please move current oraInventory to some other location.
Install 10.2.0.2 Software on a separate home. Follow installation steps.
Don’t create a database, so uncheck that option in the screens of Installation.
Once done it will ask for root.sh to be run. This completes the 10.2.0.2 installation.
After that go to companion software start the installation of that. Only thing to be taken care in that is to specify the ORACLE HOME correctly I,e in this case the new 10.2.0.2 home created. And in the screen select the 2nd option and rest Follow general instructions in that.
Once that completes apply the 10.2.0.4 patchset on the same ORACLE HOME I,e again 10.2.0.4.This completes the 10.2.0.4 Installation.
Once Completed stop the database and listener on 10.2.0.1 ORACLE HOME , and go to 10.2.0.4 ORACLE_HOME/bin.
Run dbua from there and select the database to be upgraded.If the database is not visible in the options check the oratab , if the entries are correct in that , if not update the same.
In the screens to follow uncheck the screens for Flash Recovery Area ,Configure Enterprise Manager and recompile invalid .Once done run utlrp.sql manually to recompile invalids.
Once done with that configure listener using netca or manually copying files from old ORACLE HOME to new ORACLE HOME and change the paths accordingly.
Issue Faced may be ORA-1031 Insufficient privileges
A connection to the database using SQL*Plus fails with same error:
% sqlplus /nolog
SQL> connect / as sysdba
ORA-1031 Insufficient privileges
Resolution
1.add the user oraclep to dba group in /etc/group.
2. add the group I,e dba16 to config.c in rdbms/lib in the 10.2.0.4 ORACLE_HOME.

Cloud Computing Concepts
CLOUD COMPUTING
What is a cloud?
• Virtualized server pool
• Reconfigures to provide different service profiles on demand
• Individual node providing service is unimportant
Cloud computing Technical means:
Providing services on virtual machines allocated on top of a large physical machine pool
Cloud computing in Business means:
A method to address scalability and availability concerns for large scale applications
Cloud computing some people say is Democratized distributed computing
While there are several definitions of what constitutes a Cloud and what the term Cloud Computing really means, simply put, Cloud Computing allows users to tap into a virtually unlimited pool of computing resources over the Internet (the Cloud).Unlike traditional IT, Cloud users have little insight or control over the underlying infrastructure, and they must interact with the Cloud via an API provided by the Cloud vendors. The most exciting part of the Cloud, however, is its elasticity and utility-style pricing. Users can provision resources dynamically in a self-service manner and pay only for what they use – much like how we use utilities like electricity or water.
Amazon Web Services (AWS) offering: The AWS cloud provides reliable and dependable on-demand infrastructure that frees time and expense for you to focus on innovating for your business.
Costs
Eliminates up-front capital expenditures significantly reduces ongoing operational expenses Offers a pay-as-you-go utility computing model
Lowers Costs
Eliminates hassle of configuring data centers Reduces time to pilot and test projects Enables you to focus on adding value to your business
Reduces Time to Market Offloads Heavy Lifting
Gives you access to massive data centers maintain the flexibility your business demands Use only the capacity you need, when you need it
Many Uses for AWS
• Elastic computing
• Media distribution
• Scalable Web sites
• Business continuity (backup/recovery)
• Record retention and management
• Financial applications
• High-performance computing
• Software development/testing
AWS In the Enterprise
Use development platforms you already know
Fast access to compute power and storage
Automatically scale to the needs of your business
Pay only for what you use, with no commitments
Secure, dependable, and fast infrastructure services
Easily provision resources for one-off projects
Service the needs of the entire organization without jeopardizing in-progress projects
Cloud Computing and Oracle
Cloud computing seems to be where the future of enterprise computing lies and as one of the leading players in the field of enterprise computing, Oracle has taken a proactive approach to the opportunities offered to it by the cloud.
The company, for instance, announces the release of a product line that is tailor-made for the cloud. These products allow users to not only conveniently deploy their Oracle applications in the cloud, but to also back up their Oracle databases in the cloud, just as they would on an in-house server. This is something that Oracle is doing in partnership with Amazon through their web services arm, whose cloud computing service (known as Elastic Cloud Compute) has proven to be one of the first real successes in this emerging field. Oracle promises to team up with other cloud platform providers in the near future, in a complementary role (where the other providers offer the platforms, while Oracle offers the kind of applications that are able to withstand the demands of the cloud).
Many analysts also see Oracles ventures into the cloud, though enthusiastic, as more of a way of attempting to protect its enterprise computing turf, since there is a real risk of a client switching software providers during their migration into the cloud, if their current provider doesn’t develop applications that can run in the cloud.
While the Cloud has created a loyal set of followers – mostly among web startups and developers – enterprises have found it somewhat difficult to fully utilize due to a variety of reasons, including unavailability of enterprise software, data security and privacy issues, etc. Oracle is addressing this challenge by introducing products and services that will help make the Cloud enterprise-ready. Using the new Cloud offerings from Oracle, enterprises will be able to leverage the Cloud to meet transient and unanticipated demands by treating the Cloud as an extension to their on-premises data center.
The ability to back up Oracle Database in the Cloud is a key part of Oracle’s Cloud offering. It allows customers to use Storage Clouds, such as Amazon Simple Storage Service (S3), as their next-generation offsite backup storage destination.
Compared to traditional tape-based offsite storage, Cloud backups are more accessible, faster to restore under most circumstances, and more reliable.
Exciting developments taking place in the area of Cloud Computing present new opportunities for enterprises. By introducing the capability to backup databases in the Cloud in a secure and efficient manner, Oracle is leading the effort to make the Cloud relevant to enterprises. Backups in the Cloud provide enterprises with a next-generation offsite backup storage solution that is always accessible, faster to restore under most circumstances, and more reliable. Continuous accessibility of Cloud backups opens up new possibilities that have not been possible with tape based offsite storage. With its unlimited capacity and extremely attractive consumption-based pricing, the Cloud can help enterprises avoid up-front capital expenditure and become more agile, efficient, and competitive - with Oracle helping pave the way.
Oracle’s goal is to make cloud computing relevant to enterprises by
• Providing right set of products and services
• Lead the industry efforts in developing Cloud standards.
• ensure data security, etc.
