CPU Quarterly - July 2014 Security Advisor and Java SE Updates Released

It is good practice to review the security updates for your Oracle products regularly. They are updated quarterly with latest just published (July 2014).
The Oracle Critical Patch Update Advisory lists best practices and latest patches with scope making Oracle products more stable and robust.
TheMOS authentication needed PSU and CPU July 2014  Availability Document gives a comprehensive listing of recommended patching  for products and releases effected. Note that all effected components of a product are listed there.

For example for an 11.1.2.2.0 Forms/Reports environment follow this navigation path:

  • "Patch Availability for Oracle Products"
  • "Oracle Fusion Middleware"
  • "Oracle Fusion Middleware"
  • 3.3.17.4 Oracle Forms and Reports 11.1.2.2

 leading to Table 78. There are references for Java SE, JRockit, WebLogic Server, Database client, Oracle ADF,
OPMN, HTTP Server that are strongly recommended to review an implement. Even though Forms/Reports may not be effected directly, partner components need an update.

 An important part is always Java. With July 2014,  Java 8u11, 7u65, 6u81, and 5u71 are now in place (8u11 and 7u65 are publicly available through OTN).  The Information Center: Installation & Configuration for Oracle Java SE (MOS authentication neededDoc ID 1412103.2) will give more details on Java SE  download and installation.

QR Codes in Oracle Reports

 QR codes are pretty popular, especially for paper based workflows and in logistics. "Quick Response Code" is a two dimensional (2D) visual representation of any alphanumeric string. Main purpose - same as with barcodes - is to integrate paper with computers, aka offer machine readability.

Depending on the use case, different variations of QR codes are established, like Micro-QR-Code, Secure-QR-Code (SQRC), iQR-Code. Typically their specifications differ in dimension and number of elements (which basically refers to the amount of data  that can be represented with it).

Also several (country specific) industrial standards (like JIS X 0510, GB/T 18284, ISO/IEC 18004) as well as de-facto standards (like OpenSource XZing) are in place, and so do many programs generating them (QR Code Generator).

QR Code Sample

Oracle Reports has the ability to integrate external Java programs while the report is executed. Existing reports can be modernized that way and additional functionality can be added. A nice use case is demonstrated for the Barcode Bean. The barcode is generated on the fly and added for any destination format. Find details about the concept, implementation and coding in

Chptr. 43 Building a Report with a Barcode

of the main reference manual Oracle® Fusion Middleware Oracle Reports User's Guide to Building Reports 11g Release 2 (11.1.2).

For QR Codes integration into Oracle Reports, the same concept comes into place:

How to Generate 2D Barcode / QR Code in Oracle Reports (Doc ID 1678110.1)

This brand new sample code comes with demo RDF, Java coding required and setup instructions. It is based on OpenSource QR code generators.

Give it a try and let us know your experience!
