Oracle APEX Best Practices explains how to build robust and secure APEX applications. The authors have a proven track record in the Oracle APEX world.
- Iloon Ellen Wolff working in Oracle Support and is closely involved with the Oracle Database Cloud Service . A few years ago, I attended an Oracle Seminar presented by Iloon. The title was Application Express : Best Practices (rings a bell?).
- Alex Nuijten, a collegue, is well known about his presentations about database features like analytic functions (features as in functionality, not the Oracle definition: unexpected behavior not classified as a bug ).
- Learco Brizzi which was one of the builders of the Dance-Tunes application, one of the first web shops build in HTMLDB, the old name of APEX. A nice example which convinced me that you can use APEX to build enterprise applications in APEX and make money with it.
Well, I don’t like Mondays, I don’t like getting up early, I don’t like flying and I don’t like beer either. On Monday july 16th, I got up very early and took the plane to Munich to join the “SOA Suite 11g advanced” training. This training was a track of the Oracle Fusion Middleware Summer Camps organized by Jürgen Kress. The other tracks were “ADF for BPM Suite 11g advanced training” and “WebCenter Sites 11g advanced training”. About 25 participants from several (mostly) European countries showed up for the SOA track. In this blogpost I will share some of my experiences of this three-day training.
The Simple Network Management Protocol (SNMP) is a lightweight protocol for monitoring devices on a network, for instance servers. The protocol distinguishes between administrative computer(s) who’s responsibility is the monitoring of other devices called agents. Communication between manager and agents is established by Program Data Units (PDU). An example of a PDU is a trap, an asynchronous notification from agent to manager.
The Oracle Service Bus (OSB) supports SNMP traps as part of the configuration of an alert destination, it’s enabled by default but nothing will happen if an alert is created in a message flow. In order to get the SNMP trap working, some configuration of the Weblogic Server (WLS) has to be done.
The Oracle JCA database adapter enables the communication between a web service and a database object, for instance a stored procedure. With the adapter configuration wizard, part of JDeveloper 11g, meta data is generated design time and used run-time to control the behaviour of the database adapter. In this hands-on we show how to set run-time the databaseÂ by overriding the design time selected database in the Oracle Service Bus 11g. (more…)
Starting WebLogic managed servers without providing username and password manually – SOA Suite 11g tip
After installing the Oracle SOA suite 11g, you will notice that you have to enter username and password for each managed server during startup and shutdown. This in contrary to the administration server where you don't need to enter username and password at startup. I was wondering if there was an easy way of skipping this manual step for the managed servers as well.
And yes, there is an easy and elegant way to prevent entering credentials every startup and shutdown. Just follow these steps:
1 Create a boot.properties file.
Create a plain text file called
boot.properties with the following content:
2 Place the boot.properties file in the security directory.
Save or copy this file in the
security directory under the managed server root directory. This directory was not created at installation time, so I had to create it myself. The server root directory is located at
3 Start the managed server.
The server will read the credentials from the
boot.properties file and in case of plain text username and More >
