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...)

Oracle Service Bus: Pipeline alerts in Splunk using SNMP traps

Oracle Service Bus provides a reporting activity called Alert. The OSB pipeline alerts use a persistent store. This store is file based. Changing the persistent store to JDBC based, does not cause pipeline alerts to be stored in a database instead of on disk. When the persistent store on disk becomes large, opening pipeline alerts in the Enterprise Manager (12c) or Service Bus console (11g) can suffer from poor performance. If you put an archive (more...)

Expose custom application logging on WebLogic in Log Analytics

Custom applications – standard Java EE, ADF or other Fusion Middleware such as SOA Suite – on WebLogic can produce logging through the WebLogic Diagnostics Framework (WLDF). Simply put: write log messages using Logger classes similar to standard Java Log and Log4J – read this article by my colleague Aino Andriessen for some details: https://technology.amis.nl/2011/01/12/oracle-diagnostics-logging-odl-for-application-development/ and this three part series by Duncan Mills: https://blogs.oracle.com/groundside/entry/adventures_in_adf_logging_part .

Fix “BEA-000394: Deadlock detected” for Weblogic with ADF Applications 12.2.1.2

If you try the newest version 12.2.1.2 (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 10.0.0.1. 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

BPM Worklist API 12.2.1.1 and Custom ADF 12.2.1.1 Application

I have updated my sample app with BPM API usage in ADF application to 12.2.1.1. Originally this was developed with ADF/BPM 11.1.1.7 - Dynamic ADF Buttons Solution for Oracle BPM Outcomes. There are several changes in BPM libraries usage. I will describe it all step by step.

Download sample application - adfbpm12211.zip. This archive contains both BPM and ADF app. BPM process implements two roles - request holiday (more...)

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...)

Unable to login with a SQL Authenticator

For a project, we are migrating Forms to ADF.
There is also a number of reports which are not to be migrated yet.
Therefore, we need to keep the users in the database.
As we do not want to maintain two user stores, we thought it to be a good idea to create an authenticator in WebLogic to authenticate to the database.
There are loads of blog posts / support notes on how to configure (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.

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:

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...)

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.

Veridata and boot.properties 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.

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
