The aim of this post isn´t write a complete guide about the installation process.
There are a good tutorials in internet and oficial doc is very clear
I will write about some important things that you should keep in mind before the installation.
Install a correct JDK
7.0.13 is a good option.OpenJDK can be good for Weblogic but not for Forms
rpm -ivh jdk-7u13-linux-x64.rpm
Register your JDKs for alternatives and change the current java version
In this case remember you need a grant grant change notification to hr
In DCN You need to explicitly unregister a registration to delete it from the server and release the resources in the driver. You can unregister a registration using a connection different from one that was used for creating it
With DCN you could have problem with some column types.
ORA-29977: Unsupported column type for query registration in guaranteed mode
Check if in your query you have a blob,clob or xmlType column
Websockets have a default timeout in 30s
you can configure this time and other parameters in web.xml
Another day someone in the OTN forum asked how to clean the resutls in a af:table.
We can do it with code, working withe the ViewCriterias of the ViewObject, but also we can add a hide funcionality in the af:table.
If we add a new column with the property rowHeader a true, our table will have a new column with a button to clean the filter in the tables
