‘No such file or directory’ on starting your domain

Today I was triggered by this question. Earlier I had a similar problem, where I searched, and searched and searched and found the last section on this blogpost. Yes indeed, that is how it works when you blog: you might find your self finding your own blogposts again.

What is it about? Last year I wrote a nice set of scripts on installing Fusion Middleware and creating Fusion Middleware Weblogic domains.

I created the domain-creation-script (more...)

New and improved (re-)start and stop scripts for Fusion MiddleWare.

Last year I created a set of start and stop scripts for Weblogic/Fusion MiddleWare. Although I was quite happy with them at the time, I found that there was quite a lot of duplicate code. And I think I could improve them by combining at least the wlst scripts into one, making it a lot better maintainable, but also opening up for restart functionality. And doing so make the scripts more generic. I took my (more...)

BPM BAC Subversion Server refusing connections

These days I work on setting up several development lifecycle environments for BPM, SOA and OSB. What means that we setup servers for Development and test, culminating eventually in supporting the setup of the acceptance and production servers.

Since we want to have development resemble production as much as possible, we installed a dual-node clustered BPM environment, including BAM. However, since it is development, we have the two Managed Servers per cluster on the same (more...)

Back from PaaSForum

So, and now we're back in business after a splendid week in Split, Croatia, to meet with about 200 great, enthusiastic con-colleagues from the fields of SOA and Weblogic. It was the yearly OPN Partner Community Forum, ran by the great Jürgen Kress. He did a formidable job to collect many informatic sessions on the latest news and products from Oracle. We could meet with product managers, eat  and drink with them. To my surprise (more...)

Start, Restart and stop OHS Components

In Fusion Middleware 12c the Oracle HTTP Server is now configured as SystemComponents within a Weblogic Domain. This can be embedded in a FMW Domain, like SOA, OSB, or WebCenter.  Or it can be in a stand alone domain.

When configured, there are scripts to start and stop the system components in the bin folder of the domain: startComponent.sh and stopComponent.sh.

These scripts first do a readDomain() to read the domain before actually (more...)

Red Samurai and Oracle PaaS JCS Success – JET/ADF BC REST Cloud Production Application

I would like to share our success in Oracle PaaS service - Java Cloud (JCS). We have managed to implement JET/ADF BC REST system in short period of time and deploy it in production running on Oracle JCS. UI is implemented entirely with JET, while back-end REST services are running on top of ADF BC. Secure access is controlled by unique ID managed by server side ADF Security.

Production application implements custom invoice processing logic (more...)

Significant Improvement for WebLogic Start-Up Time on macOS Sierra

I have faced really slow WebLogic start-up times after upgrade to recent versions of macOS Sierra. It turns out to be common problem related to JVM start-up on macOS systems, nothing to do with WebLogic itself. Solution is to register mapping between and your computer name in hosts file, read more on Stack Overflow - Jvm takes a long time to resolve ip-address for localhost. This issue seems to appear with (more...)

Install and configure Oracle HTTP Server Standalone

Last week I had an assignment to install and configure Oracle HTTP Server as a reversed proxy in a DMZ. Many years ago I worked with Apache a little, so I had not have the details at hand.

Although installing and configuring the HTTP Server is not hard, I found that I had to do quite some searching around to get to all the essentials. To help you out, and to have it logged for (more...)

Fix “BEA-000394: Deadlock detected” for Weblogic with ADF Applications

If you try the newest version (or maybe earlier versions too) you see, that your managed server does not restart, when

  • you have deployed your ADF application(s)
  • you try to restart the managed server with ADF
  • you use intentionally or not shared libraries in your weblogic-application.xml (see example below)
<?xml version = '1.0' encoding = 'UTF-8'?>
<weblogic-application xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Weblogic 11g to 12c: strictness in listen address

Let's say you have a virtual machine with two network adapters, both set on 'HostOnly'.
I used to do that and set the first one of those to a fixed IP address, say To this one I coupled the hostname, for instance darlin-vce-db, using the /etc/hosts file. That way I had a fixed, always existing network address for the database.

Together with the database, you install WebLogic, for instance to serve (more...)

Use WLST to test all your datasources

To day I had some problems with deploying my composite to the server of my current customer. Apparently the Server had some problems with datasources. But since there are many I did not feel much for checking them one by one with the console. Using Google I got the following examples

The third one on Creating weblogic user, now for SOA Suite

A few months ago I figured out how to create specific users with restricted access to Service Bus components. I blogged about it in part 2 of creating WebLogic users for ServiceBus 12c. But the series lacks an explanation on restricted user access on SOASuite.

Today in a question about Roles on Oracle Community Forums, the reference to this elaborate blog entry was given: Restricted View, by Antony Reynolds.

I think that blog (more...)

Generate Admin Channels to improve Weblogic Admin Console performance (and of FMW-Control)

At one of my customers we have quite an impressive domain configuration. It's a FMW domain with SOA, OSB, BAM, WSM, MFT in clusters of 4 nodes. The thing is that when having started all the servers, the console becomes slooooooowwwww. Not to speak of FMW Control (em).

One suggestion is to set the 'Invocation Timeout Seconds' under MyDomain->Configuration->General->Advanced to a value like 2. And 'Management Operation Timeout' under Preferences->Shared Preferences to a value like (more...)

Set all WebLogic log levels to “Inherit” via WLST

Logging is a very useful feature of WebLogic.

Unfortunately the log levels, which are set after a clean install of WebLogic or some of the Fusion Middleware product creates a lot of noise and therefore it costs I/O performance.

Additional after analyzing an issue with logging often resetting the log level is forgotten.

Here you get a script to reset the log levels at regular intervals or after a trace session.


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.

Test your WebLogic 12.1.3 enviroment with Robot

Robot Framework is a generic test automation framework which has an easy-to-use tabular test data syntax and it utilizes the keyword-driven testing approach. This means we can write our tests in readable and understandable text. If we combine this with the REST Management interface of WebLogic 12.1.3 we are able to test every detail of a WebLogic domain configuration and when we combine this

Create with WLST a SOA Suite, Service Bus 12.1.3 Domain

When you want to create a 12.1.3 SOA Suite, Service Bus Domain, you have to use the WebLogic config.sh utility.  The 12.1.3 config utility is a big improvement when you compare this to WebLogic 11g. With this I can create some complex cluster configuration without any after configuration. But if you want to automate the domain creation and use it in your own (provisioning) tool/script then you

Oracle SOA Suite 12c tips – Tuning the SOA infrastructure thread pool

One of the new capabilities of Oracle SOA Suite 12c is the ability to control the SOA infrastructure thread pools, except the resource pools for EDN and the adapters, with Oracle WebLogic Server work managers. Each partition will has its own work managers defined. This allows you to separate services in partitions and, to some extent, tune them separately based on for example specific SLA requirements.

Well, this blog posting is not about explaining the (more...)

The WebLogic Server and Trust Stores

I will describe how you configure trust stores for the WebLogic Server.


Chain of trust

When a SSL server certificate is issued by a CA it is signed by a another certificate. Normally this will be an intermediate certificated, that is again signed by the CAs root certificate. So there is a chain of trust between the (more...)
