Installing Oracle Forms/Reports 11.1.2.2.0 on Red Hat 6

Here is my experiences with installing Forms and Reports 11.1.2.2.0 on Red Hat 6 (64-bit) using Java 7.

Overview

The WebLogic Server and Trust Stores


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

Overview

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...)

Deploying Jenkins to a WebLogic Server

I am working on a project that uses Jenkins. We had a couple of different options for deploying Jenkins.
We use Red Hat Linux, so we could run Jenkins as a command line service in the background, or we could deploy it to a servlet container like Tomcat or Glassfish. But since we are already using the WebLogic Server it made most sense to deploy Jenkins there.

Using WebLogic for Jenkins does not work out (more...)

Tools that I use – uptimerobot.com


http://uptimerobot.com is service that can monitor if you sites are up and running. I have been using it for more than 3 years and it works very well.
The service is free and you can add up to 50 monitors. It is easy to configure a monitor. You don’t have many options, but it can do just what I need.

You can create 4 types of monitors.

  • http(s): that’s perfect for website monitoring. The (more...)

WLST script for listing WebLogic Server memory usage

Here is a short script for listing Java heap usage for all WebLogic Servers in a domain.

domainRuntime()

servers = domainRuntimeService.getServerRuntimes();
print('################################################################')
print('# Java heap information per server')
print('################################################################')
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))

The Oracle SOA Suite and the OSB are now free for developers!

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...)

Tips and tricks for installing and maintaining FMW products

I have written an article for the winter 2014 issue of OTech Magazine.

Unfortunately, something went wrong in the layout process so it does not look too good everywhere, but it is readable.

The site uses some kind of widget to display the magazine. I could not get it working on my iPad and a colleague had problems with IE. If you run into problems, you can download the pdf directly via this link.

UKOUG Tech13 – Best Practices for Installing Oracle Fusion Middleware Products

Yesterday I did my UKOUG Tech13 presentation “Best Practices for Installing Oracle Fusion Middleware Products”. You can download it here.

I have not done any conference presentations since 2007, so I was a bit nervous :-)

It did not go perfect, but after a little bit, I warmed up and it (more...)

UKOUG Tech13 WebLogic Hackathon

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...)

UKOUG Tech13 WebLogic Hackathon


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:

OTN Developer License restrictions

Oracle allows you to download most of its software free of charge via the OTN Developer License.

This is a fantastic option that I appreciate a lot. But it is important to understand the restrictions of the license.

So as soon as you go into to production with a project you need proper licensing. This is true for all the software installation you have.

If your developers are fixing bugs or developing version 1.1 (more...)

Oracle FMW Error Correction Support Policy

Oracle Lifetime Support contains a lot of different features. It is not only technical support through My Oracle Support.

The Support Policy has 3 support stages:

  • Premier – 5 years from general availability (GA) date
  • Extended – 3 years extra (Normal support fee + 10-20%)
  • Sustaining – Perpetual (Normal support fee + 10-20% + inflationary adjustment)

Not all products have Extend support.

Not all support features are available in all stages.

Sometimes Oracle will extend (more...)

Tools that I use – nmap

For medium to large size projects the network setup can be quite complex, especially if it involves several external partners or third-party networks (VPN, MPLS etc).

Normally network changes are done by network engineers that do not have access to the servers and therefore cannot verify the changes they make.

When I have to verify a network change, firewall opening, NATing etc, I have in the past often used telnet.

This is very simple and (more...)

Oracle Forms and Java 7u51

Java 7u51 is scheduled for release in January. It will have some consequences for you Forms installation that you need to address.

As far as I know there is no problems with using 7u51 on the server side, only on the client side.

Overview

Jar signing

7u51 requires you to sign all RIAs (Applets and Web Start applications).

Oracle already signs the standard jar (more...)

WebLogic Server and entropy

After input from Jacco H. Landlust and Edwin Biemond I have rewritten my post about entropy.

Overview

Entropy pool

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...)

Installing ADF 11.1.2.4.0 on Red Hat 6

Here is my experiences with installing ADF 11.1.2.4.0 on Red Hat 6 (64-bit) using Java 7.

FMW releases are big and complicated. Between the main FMW releases, Oracle release some products on separate “branches”. This is to fast track new features.

ADF 11g Release 2 is such a fast track product. The latest ADF 11g release 1 version is 11.1.1.7 and the latest release 2 is 11.1. (more...)

Using opatch to list valid FMW Homes to apply a patch to

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...)

Bash script for installing WebLogic Server PSU patches via BSU

Patching WebLogic is necessary but not fun. To help out I have created a simple Bash script for installing CPU/PSU patches.

For information about CPU, PSU and SPU patches check this post.

The script is using BEA Smart Update so it is for WebLogic Server 12.1.1 and older. WebLogic Server 12.1.2 has switched from BSU to OPatch.

Easy way to display ADF version for FMW installations

Extra from jar files

# FMW 12.1.2
