Create a CA, issue server/client certificates and test them via Apache

Here is a quick way of creating your own CA and issue server and client certificates via OpenSSL.

JRockit Real Time

Since JRockit is dead this post might not be interesting, but anyway …

I have never used JRockit Real Time (JRRT). At a customer site I could see that JRRT was installed and the custom said that they used it.

Protect the Apache HTTP Server against CRIME SSL/TLS attacks

It is now possible to protect Apache on both Windows and Red Hat servers against CRIME SSL/TLS attacks.

Using the Apache HTTP Server as a forward proxy to the Internet

Often you do not want servers in your internal network segments to be able to access the Internet directly.
One way to get controlled access to the Internet is to place an Apache HTTP Server in a DMZ network segment. Internal servers can then use the Apache server as a (more...)

Using the Apache HTTP Server (mod_proxy) as a reverse proxy to a WebLogic Server

If you are using a WebLogic Cluster you need a proxy in front of the cluster to provide load balancing. You need either a hardware load balancer or a Web Server with the Oracle Web server plug-in.

Even if you are not using a Cluster it makes sense to place (more...)

Work Managers in WebLogic Server

I found a brilliant Work Manager demo video by James Bayer. There also is a accompanying slide show.

James also has an older post where you can download the source and the war file. It is great when you can get your hands on the source of demos so you (more...)

No Apache httpd Windows binaries from the Apache Software Foundation

I have only used the Apache HTTP Server on Windows for a couple of years since I mostly use Linux.

Until now I have downloaded the binaries from the Apache Software Foundation or one of its mirrors.

I have been missing the latest releases (2.2.23 and 2.2. (more...)

Silent installation of the OSB on Red Hat 6

In this post I will describe how to do a silent installation and configuration of the OSB.

Getting the size of the HTTP Session State in WebLogic

I recently had to find the size of the data stored in the HTTP Session State. On MOS I found this note:
“Session Replication Fails Due To Non-Serializable Object: JSP Test Page [ID 1073386.1]“.
It contains a JSP test page that will show you if your session data is (more...)

Creating a Data Source via WLST Offline

I have been messing around with silent install of FMW and creating domains via WLST. I was initially trying to get as much as possible done via offline WLST and therefore wanted to create a Data Source. I could not find any examples online which was a bit puzzling since (more...)

SSL Server Certificates – Lessons learned

It is not difficult to create an SSL/TLS certificate and configure an Apache HTTP Server to use it. But I found that there are some things you need to know that does not necessarily make much sense. Here are some lessons learned and a couple of tips.

Hardening the Apache HTTP Server

After having been through security audits over the years I now have a short list of things I always change after having installed an Apache HTTP Server.

It is not much, but it always moves the focus from the Apache server to the applications and thereby off my desk :-)

Enterprise Manager will not start after ADF upgrade

I recently had to upgrade a WebLogic Server with ADF for a customer. It was WebLogic 10.3.4 to 10.3.6 and ADF 11.1.1.4 to 11.1.2.3. They also used Enterprise Manager.

Everything went fine except for the Enterprise Manager which ended up (more...)

Auditing users in WebLogic Server

If you do a default installation of the WebLogic Server user activity is not audited. WebLogic has a build in Auditing Provider but it has to be enabled.

The Audit Provider can log these events.

To enable it via the Admin Console got to Security Realms => myrealm => Providers (more...)

Is your WebLogic Server slooow? Might be because of low entropy

On Linux low entropy can cause certain operations to be very slow.

SSL operations need entropy to ensure randomness. Entropy is generated by the OS when you use the keyboard, the mouse or the disk.

If an SSL operation is missing entropy it will wait until enough is generated.

Configuring outbound SSL for the SOA Suite

A customer had a situation where they had to call a remote Web Service from the SOA Suite via https. (One-way TLS/SSL). The developers had deployed the SOA Application so I had to configure the SOA Suite to trust the key used for SSL. For unknown reasons the normal Weblogic (more...)

Adding an extra IP to a Windows 2008 server (Source IP problem)

An Apache http server does not support more than one SSL virtual host on the same IP address and port. So if you want to host two Internet domains on the same server and they both use SSL on port 443 then you must use two IP-addresses.
