Some problems you can find are:

Remember you must have WebLogic running:

Install Oracle Forms 11gr2 on OEL 6

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

/usr/sbin/alternatives --install /usr/bin/java java /usr/java/jdk1.7.0_71/bin/java 17071
# /usr/sbin/alternatives --config java
  • Configure your etc/hosts with your correct name   forms forms.formsdomain   forms forms.formsdomain

if you want to know the domain and host name you can try run this comannd

echo `uname -n`.`awk '/^domain/ {print $2}' /etc/resolv.conf`

It´s important have a IP and not init the installation without IP

  • Increase the tmp size in /etc/fstab until 6GB
tmpfs /tmp tmpfs nodev,nosuid,size=6000m


ADF with WebSockets Tips.

In these days everybody talk about the WebSokects  integration with ADF.
In this post I will give some advices about this integration.

  • You can use WebSockets in combination with Database Change Notification(DCN)
    • 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
  • WebSocketAdapter now is deprecated, here you have oficial doc to build WebSockets in weblogic.

With WebSockets you can build something like that



LOV with create option

Then above of the  table result appear a buton to open the new popup to create rows.

MongoDB and ADF

This week I have been learning MongoDb and I’m looking for some ways to connect MongoDB with ADF Faces.
We can use Bean or EJB DataControl.
Another way could be in combination with ADF Faces

Here there are another way
