Moving APEX application to the Oracle cloud

Just read an interesting blog post about moving an Oracle APEX application to the Oracle cloud.  Interesting because I have previously used APEX and migrated some of the apps to Joomla.

Oracle announces MySql changes

oracle
At Oracle OpenWorld this week there were a few changes announced for MySql.  Oracle has issued an open source MySQL 5.6 release candidate.

Oracle issued its first MySQL 5.6 preview in July of 2011. For certain types of queries, there has been a performance gain of as much as 200 percent.

MySQL 5.6 includes sub-query optimizations that improve the query execution speeds. The underlying InnoDB storage engine has also been enhanced for throughput performance.

Under Oracle's guidance the number of new features per release has been cut down to be more manageable. While at the same time, there is more effort going into testing and overall quality.

From a release perspective, Oracle believe that users don't want to upgrade their databases often with big feature releases.  It is noted that Oracle has been coming out with a regular stream of maintenance releases though, as the 5.6 release is being developed. The current plan is for major new releases of MySQL every other year. That would place a MySQL 5.6 generally available release for early in 2013.

Oracle 12c - Pluggable databases.

oracle
Larry Ellison at the Oracle OpenWorld conference earlier this week, provided the information that the forthcoming Oracle Database 12c (the c standing for ‘cloud’) will  feature a radical new architecture called pluggable databases.

Currently a server running an Oracle database has an individual set of server processes.  Adding a second database to the server adds additional processes for the second database.  Pluggable databases will allow multiple databases to run under one copy, or instance, of the Oracle database software, a feature he called "multitenancy."

As the name implies, pluggable databases allow multiple tenant databases to run under one copy of Oracle 12c.  An arbitrary number of up to 250 user databases, can be run under the new architecture, and the architecture could probably support more. The new database is reportedly compatible with older Oracle databases.

This change in architecture brings a number of benefits that Oracle touted through the week, including improved efficiency, stronger security and easier upgrades.

However there are a few challenges for database administrators especially in the area of allocation computational resources. How will the new workload characteristics of running multiple databases on a single server be determined. The characteristics of the optimum size of a server, in reference to memory and storage space, may also/will need to be reconsidered.

Interesting times lay ahead.  Oracle Database 12c is set for availability in 2013.

New Releases Oracle SQL*Developer * SQL*Developer Modeller

Having been busy recently I nearly missed the recent announcement of Oracle SQL*Developer 3.2.0.09.30 and SQL*Developer Data Modeller 3.1.2 (704).

Both available on Oracle Technet.

Oracle Goldengate


I was talking with a colleague the other day about Oracle Goldengate and it was strange that I saw this article which describes the recent release. Having used the product and its ‘relation’ Streams, it was interesting to catch up on the recent changes.

End of the line for Oracle Discoverer?

Having used Oracle Discoverer for many years and developed a few applications for clients using the tool, it was sad to see the statement of direction from Oracle in January 2009 encouraging users to migrate to Oracle Business Intelligence.

Whilst recognising that things cannot stand still Oracle Discoverer was a very good relatively light weight product.  Oracle Business Intelligence whilst being a good product doesn't really class as light weight, which ever way one looks at it, requiring a Web server and all that that entails.

This recent article is just another encouragement to those Discoverer users to migrate.  Could we soon be seeing the nail in the Discoverer coffin?

Oracle Express 11g and Goldengate to SQL server

I see that Oracle has release Oracle Express 11g for windows 32 bit and Linux 64bit system.   You can get it from the link below.

I also saw this interesting article about using Oracle Goldengate to connect to Microsoft SQL Server.  I find this of interest due to previous experience using the 'Transaparent Gateway' to get information from SQL Server to Oracle for a client.  I enclose the link for those of you that may want to have a look.
