I - Java in the database, JDBC, UCP, DRCP, Application Continuity, Transaction Guard
II - Oracle Datasource for Hadoop (OD4H), In-Database Container for
Hadoop, Orale Datasource for Spark
All topics discussed here represent my own opinions and speculations.
PyOhio "The Free Ohio-based Python Miniconference" is on Saturday & Sunday July 25-26 at Ohio State University. On Sunday Catherine Devlin and Oracle Technology Network's Todd Trichler will have an Oracle/Python/Linux Tutorial.
I am no XML expert but my first interest for the book stems from the fact that wether you like it or not, XML is everywhere; so better embrace it. The book furnishes a comprehensive coverage of all things related to XML including: creating and parsing an XML document, creating and validating an XML Schema, XPath , transforming XML with XSLT, JAXB, Oracle XML Developer Kit (XDK 11g), Oracle XML Publisher, comparing XML documents, converting XML to PDF or MS Excel, even Berkeley DB XML edition.
I have used JDeveloper for doing prorotyping work and proof of concepts related to JDBC, Java in the database, and Database Web Services but, and this is my second interest for the book, i have no idea that JDeveloper furnishes so much capabilities for processing XML documents.
I now have two good reasons to keep and use my copy of this book. For these reasons, i recommend it.
A summary of my talk at PHP Quebec @ http://conf.phpquebec.com
PHP is widely adopted for database-backed RIA.
PHP lacks true connection pool; can a commodity database server sustain 20000 concurrent users?
How to ensure availability in the face of a database server failure?
When it comes to scalability, more PHP code or more frameworks (i.e., classes) translates to more CPU power; how to simplify PHP programming and reduce the amount of PHP code using built-in Oracle database 11g mechanisms?
The Community Connect case study will be discussed.
"CCI has been collaborating with Oracle's development group to improve memory utilization and reduce overhead across multiple nodes of DBMSs, using connection pooling called Oracle Database Resident Connection Pooling (DRCP). A connection pool is a cache of database connections maintained by the database so that the connections can be reused when the database receives future requests for data. Opening and maintaining a database connection for each user can be time consuming and waste resources. Open connections are placed in a pool to be reused."
