Last week I presented at the UKOUG’14 conference on instrumenting, analyzing, & tuning the Performance of Oracle ADF Applications. Instrumentation refers to an ability to monitor or measure the level of a product’s performance, to diagnose errors and to write trace information. Instrumenting gives visibility and insight of what is happening inside the ADF application and in the ADF framework (what methods and queries are executed, when and how often). These runtime diagnostics can be very effective in (more...)
A while ago I was contacted by a customer about their old Oracle Application and Weblogic Server environment.
They were receiving complaints from users that they can’t connect to the secure site any longer. Most of the complaints came from users that just recently updated their tablet or smartphone.
After a quick look in the logs of the OHS servers, I found out that the problem had to do with the SSL protocols (more...)
I am going to show how you would create a WebLogic data source to Pivotal GemFireXD 1.3. In this example I am using the developer edition of Weblogic which known as "Free Oracle WebLogic Server 12c (12.1.3) Zip Distribution and Installers for Developers" You can download / configure it as follows.http://www.oracle.com/technetwork/middleware/downloads/index-087510.htmlNote: I am assuming you have WebLogic 12C running with GemFireXD also running. I am also (more...)
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
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
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...)
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...)
Coherence can really accelerate and improve your application because it's fast, high available, easy to setup and it's scalable. But when you even use it together with the JCache framework of Java 8 or the new Coherence Adapter in Oracle SOA Suite and OSB 12c it will even be more easier to use Coherence as your main HA Cache.
Before Coherence 12.1.2 when you want to use Coherence together with
Here is a short script for listing Java heap usage for all WebLogic Servers in a domain.
servers = domainRuntimeService.getServerRuntimes();
print('# Java heap information per server')
print('%20s %10s %8s %8s %4s' % ('Server','Current','Free','Max','Free'))
for server in servers:
free = int(server.getJVMRuntime().getHeapFreeCurrent())/(1024*1024)
freePct = int(server.getJVMRuntime().getHeapFreePercent())
current = int(server.getJVMRuntime().getHeapSizeCurrent())/(1024*1024)
max = int(server.getJVMRuntime().getHeapSizeMax())/(1024*1024)
print('%20s %7d MB %5d MB %5d MB %3d%%' % (server.getName(),current,free,max,freePct))
I did not notice it myself but over Christmas Oracle made the SOA Suite and the OSB free for developers.
I found out via the January issue of the Oracle SOA Partner Community Newsletter, issued by
Jürgen Kress. You can sign-up for the newsletter here: http://www.oracle.com/goto/emea/soa.
You can download most Oracle FMW software for free on the OTN download site. Although you do not have to pay to download the software, it is (more...)
We recently upgraded our EM12c 188.8.131.52 installation to 184.108.40.206. This service was configured to authenticate logins against our Active Directory server via LDAP. However, after upgrading we found that authentication stopped working, even after recreating the Active Directory Authenticator (as required). I could see the list of users from AD, but could not authenticate them in EM!
In this post I'm going to share what we did to diagnose (more...)
WebLogic 10.3.6 comes with Jersey1.9 and has no support for Server Side Events or WebSockets. But for one of our projects we are making a HTML5 / AngularJS application, which need to invoke some RESTful services and we also want to use of SSE or WebSockets.
Off course we can use WebLogic 12.1.2 but we already have an OSB / SOA Suite WebLogic 10.3.6 environment.
So when you want to pimp your
Yesterday we conducted the SuperSunday WebLogic Hackathon at the UKOUG Tech13 conference.
It went well and people looked like they had a pleasant time.
I have enjoyed preparing for the event. The team contained a Brit, a Dutch, a Swiss and a Dane. It has been very motivating meeting people (more...)
The last few weeks I was busy re-writing of my puppet WLS module so it fully supports the power of Puppet 3 (thanks for more than 4000 downloads on puppet forge and all the github downloads).
With Puppet 3 we now can use Hiera, Iterations and Lambdas expression. This does not (more...)
This year’s UKOUG Tech13 conference is kicking off with a free SuperSunday event.
You can choose between 7 streams:
- Hands on Engineered Systems
- Analytics – Pulling the Threads Together
- Database Technology 1 & 2
- Real World Lessons from ADF Ninjas
- Extending APEX out of the Box
- WebLogic Hackathon
The best and most interesting is of course the WebLogic Hackathon
I have been working with a great group of people to prepare the WebLogic Hackathon:
Before we can describe all the new features of WebLogic 12.1.3 & 12.1.4 and compare this to the 12.1.2 version we should first take a look at the 10.3.6 version. WebLogic 10.3.6 is still the latest 11g version but Oracle (more...)
After input from Jacco H. Landlust and Edwin Biemond I have rewritten my post about entropy.
In computing you often need random numbers. They are used for encrypting stuff but also for lots of other things.
For Linux servers random numbers are default provided by the /dev/random device. /dev/random is a pool of random bits (more...)
All FMW products except the WebLogic server is patched via the opatch tool. From FMW 12.1.2 the WebLogic server is also patched by opatch.
In a FMW installation you can have many Oracle Homes. When you install a patch you need to know which home to apply the patch to.
opatch can help you figure out where to install the patch.
I have a Forms installation that I need to apply a patch (more...)
