Serving Oracle JET Application from WebLogic

Oracle JET application can be served from WebLogic as static content (HTML/JavaScript), JET code will be downloaded and executed on the client. Read more about packaging and deploying JET applications in developer guide - Packaging and Deploying Web Applications.

Here is demo JET application served on WebLogic server, port 7101. JET index.html page is referenced through application context root, registered on WebLogic during deployment of static content:

Required steps:

1. Generate JET application from (more...)

Set connection retry frequency on DataSource in WebLogic 12c.

I have encountered several times in WebLogic 12c that when the ConnectionPool of a DataSource in WebLogic could not be initialized because due to a connection error or invalid username or password, the server could not be started.

I can't remember having encounterd this problem in 11g, and this week I struggled with it with one of my customers. The perception of the DBA there was that in 11g the server did start up, but (more...)

Start and stop a WebLogic (SOA/OSB) Domain

So let's start the day with a blog. In the past few months I created scripts to install FMW products and build a WebLogic domain for it. For most of my findings I did a blog already:

Create WebLogic users for ServiceBus 12c

Last week I wrote a blog about how to create WebLogic users for ServiceBus 12c. However, I did not now how to assign a particular Application Specific Role to the weblogic user, for particular ServiceBus privileges. I did find out what particular Roles there were (see the blog). But how to assign them I found out just today.

So here it is:
def grantOSBAppRoleToWlsGroup(osbAppRole, wlsGroup):
# Grant OSB AppRole

Reset your Datasources

In most SOASuite and Oracle ServiceBus projects the Database Adapter is used. And often it is used to invoke PL/Sql functions and procedures. Actually, it's my favorite interaction method with the database, since the re-entrancy of the database adapter wizard is best there. To do a re-entrant update of a select or DML operation when for instance a column is added, is simply put often quite problematic.

But the thing is with Pl/Sql that when (more...)

Create Weblogic users for ServiceBus

At one of my customers there was the question of creating users that needed to log on to EM (Fusion MiddleWare Control) and Service bus console to be able  to deploy SB en WLS Artefacts (queues, datasources etc.) on the Dev and Test environment. And to be able to do some monitoring on Acceptance. Further more they still used weblogic as the only, shared, administrator user. For the latter Oracle recommends to create at (more...)

SOA Server (12c) not startable from script-created domain.

If you're a regular reader of this blog, you've noticed that I've been busy with creating soasuite/osb installations with weblogic domains in a scripted way.

I also optimized my start and stop scripts, that I'll post soon. All this work keeps me from writing on my BPEL book, so for those who are interested in my next episode, I hope you're patient.

But to get to that, it would be nice to have a running (more...)

Rename your Weblogic 12c AdminServer

At one of my customers we create Service Bus Weblogic Domains using a script, driven by a property file. But in one of the environments we encountered that the AdminServer was accidently called 'Adminserver', with a lower-case 's'. Now this is a very minor issue, but the administrator would like to have it fixed, since it is an anomaly regarding with other environments.

This week I got to implement my start-stop scripts (which I will (more...)

Creating FTP connection factories using WLST

Creating FTP connection factories using the Weblogic console can take a lot of time, mainly because it are multiple screens you have to click through every time. But creating these FTP connection factories can be done a lot easier and faster when using a WLST script.

The following script can be used as a base for your script to generate your FTP connection factories. I have used this script on a Weblogic 12c environment.

A couple of notes of the automatic generation of a SOA Suite/OSB domain

Earlier you could have enjoyed my article on the automatic generation of a SOA/OSB domain. Earlier this week I encountered some issues with a domain created at a customer this way.

I got the change to dive into that this week and luckily not only I learned a lot again, but I found the problem as well. I adapted my scripts. I won't repost them completely, I've created a github account, and try to place (more...)

Network considerations on an ODA X5-2

When you buy an Oracle Database Appliance (ODA) X5-2 off the shelve, you will get a machine with four times 10Gb copper Ethernet (bonded into two interfaces) for public communication and two 40Gb InfiniBand (bonded into one interface) for interconnect communication between the two ODA_BASE’s. You would think that should be more than enough. Well in most cases it is. The interconnect running through InfiniBand is stunning for RAC and the public interface should be (more...)

Start problems with Nodemanager

Since my previous long running assignment, I'm involved in a few OSB 11g to 12c upgrade trajects, where I have been working on automatic installs. Hence, my articles about automatic installs, patching and domain configuration.

When I create a new domain, 12cR2 (12.2.1), using my scripts, I'm not able to use the nodemanager of the domain to start the servers. Actually, I can't connect to it. I get it running alright, but connecting (more...)

Scripted Domain Creation for SOA/BPM, OSB 12.2.1

Recently I blogged about the automatic install of SOASuite and ServiceBus 12.2.1. It catered for the installation of the binaries and the creation of a repository.

What it does not handles is the creation of a domain. The last few weeks I worked on a script to do that. It's based on a wlst script for 12.1.3 by Edwin Biemond. This one was quite educational for me. But as denoted: it (more...)

Veridata and file

I’m spending some time building out an Oracle WebLogic/Veridata system at home. This is mostly for testing and general understanding purposes. One of the things I’ve noticed with the WebLogic server requires the username and password before the WebLogic server will start. After providing the name and password, the terminal window has to stay open because, closing it will kill the WebLogic server that is running. This leads to two interesting question and simple resolutions.


Poll a Microsoft Exchange mailbox from OSB using DavMail

The Oracle Service Bus has built in features to poll an IMAP of POP3 mail account. There are loads of excellent blog posts that exactly describe how to do it. However, when the mail server happens to be a Microsoft Exchange server, things become shady. Exchange’s IMAP implementation tends to be not really that compatible, and the server log will fill up with stacktraces such as:

javax.mail.MessagingException: Connect failed;
  nested exception is:
        java. (more...)

Username & password required at Weblogic domain startup

When installing a new WebLogic Domain for any a-specific Oracle (Fusion) Middleware application or any other implementation requiring a WebLogic domain like ORDS for instance, a new ‘home’ is created under [MW-home]/user_domains/. [MW-Home] translates, for instance, to /u01/oracle/product/Middleware.

ordsTo start your brand-new domain, or perhaps and rather, to automate the startup of your domain, you would use the supplied [MW-home]/user_domains/[DomainName]/ command-file.
This file will start the Weblogic domain (the Admin Server) and the deployed (more...)
