Solving Performance Problems on Oracle DB
 
28:11
Solving Performance Problems on Oracle DB Matthew Vegh - Embarcadero Thursday, June 26, 2014 - 11am DBAs and database developers regularly spend a lot of time tracking down and resolving performance issues on the database servers they are responsible for; it can be very difficult, frustrating, and expensive. Given the complex interactions of applications, users and databases, new performance issues can arise almost as fast as old ones can be addressed. This session will simulate common performance problems on an Oracle server and then both identify those problems and provide effective solutions. Matthew Vegh is a Software Architect at Embarcadero Technologies for the Embarcadero DB Power Studio family of products and has been with the company for the better part of a decade. He has over 15 years of development experience with a wide range of technologies and a definite preference for database tooling.

Database Time-Based Performance Tuning: From Theory to Practice
 
56:54
In this 2014 OpenWorld session, Graham Wood covers how you can identify bottlenecks and maximize database performance with Oracle’s unique database time methodology. It covers a rich toolset at the disposal of DBAs—from Oracle Enterprise Manager 12c’s Automatic Workload Repository and Active Session History features to Oracle Database’s Automatic Database Diagnostics Monitor feature—and how these tools work together seamlessly. The session also provides an in-depth understanding of how the database time methodology is used in Oracle Enterprise Manager to provide a simple yet effective method to diagnose and resolve performance problems with just a couple of mouse clicks.

http://bit.do/dSPa5 Secret sale page at EasyFrom. Watch Oracle DB Session Activity With My Real-Time Session Sampler For details about this tool, I created a special posting in my blog, A Wider View. Have a look! The tool is included in the OraPub System Monitor (OSM) toolkit (v13j), which can be downloaded Watching session activity is a great way to diagnose and learn about Oracle Database tuning. There are many approaches to this. I wanted something simple, useful and modifiable. I wanted no Oracle licensing issues. And, I wanted something I could give away. The result is what I call the Oracle Real-Time Session Sampler (OSM: ). The tool is simple to use. Based on a number of filtering command line inputs, it repeatedly samples active Oracle sessions and writes the output to a file in /tmp. You can do a \"tail -f\" on the file to watch session activity in real time!

Oracle 12c Database New Features - Pluggable Database - Video 1
 
17:25
Oracle 12c Database New Features - Pluggable Database - Video 1 1. Pluggable Database * Oracle 12c introduces a new feature called 'Pluggable Database'. Here Oracle Metadata and user data are totally separated into two sections. One is Container DB (or CDB) which will hold Oracle Metadata. The other is Pluggable DB (or PDB) which will hold user data. How does a Pluggable Database work? In the regular database, Oracle's metadata and user's application data are integrated. For beginners, Oracle Metadata is the data that is present when you install a new Oracle Database (without any sample schemas). Even though it can be called as an empty database, it still has data provided by Oracle. This data is needed by the database to function. For example, the objects owned by SYS, SYSTEM are mostly metadata. Then user data is entered into that database. They will go under multiple user schemas. Now the database is being used by the users. Now a situation arises so that we need to create another database on the same server. Why? Let us say that you need to provide data to two clients. And you don't want one client to other's data. And your data is contained in an extensive set of application schemas. In this case, making a copy of those applications schemas into a different set of names and making them reside in the same database is very difficult. So, you provide two separate databases. This also ensures that there is no security violation. So, we install another new database, which comes with Oracle Metadata. Then we load the user data. In this method, which is currently being used (Year 2013), there will be a need for more memory for both the database instances. There will be two SGAs, two sets of smon, pmon and other background processes running. Then if we need to copy one database to another, we need to rely on extensive procedures which includes exporting the data from the source database first, then removing the data at the target and then finally loading the data in there. After that, we need to take care of the user security and object privileges etc. So, if you want to provide data for multiple tenants, that is multiple clients, then with the current set of features (till Oracle 11g), we have to create multiple databases. That is, one database for one client. In otherwords, there is no multi-tenancy. Multi-Tenancy is becoming an important requirement in cloud infrastructure, these days. You would like to have the ability of providing data to multiple clients from the same database system with full confidence in security. This can be achieved in Pluggable Database. In a Pluggable Database, Oracle basically separates its metadata entirely from the user data. Metadata is stored in a section called Container DB. Then the user data are stored in Pluggable DBs. It also stores user metadata in the Pluggable DB. By the way, what is user metadata? For example, earlier, the list of user accounts that exist in a database is tightly inegrated with Oracle Metadata. Now, with the separation of Container DB and Pluggable DB, the user accounts must exist in the Pluggable DB. So, the Pluggable DB not only contains user data, but also some user metadata. So, what are the benefits? * Multi-Tenancy - We can bring in two Pluggable DBs under one Container DB. Both will be totally segregated, but yet controlled by one instance. This is an important feature for SaaS (Software as a Service) platforms, Cloud, On-Demand and Vendor Managed Application solutions. * Easy cloning/copying. Now the cloning and copying the databases across servers would be much easier. Just clone a Pluggable DB and plug-it-in in a different server. * Very easy upgrades and patching.
