Application Server

Middleware is where applications meet infrastructure. Here our consultants write about WebLogic, JBoss EAP, WildFly and Tomcat in real production environments: installing and clustering them, patching, deploying applications and finding out why something stopped working.

WebLogic – SSO/Atn/Atz – 403 Forbidden, a first issue

In a previous blog, I explained how it was possible to enable the SSO/Atn/Atz (SSO/Authentication/Authorization) debug logs in order to troubleshoot an issue. In this blog, I will show the logs generated by an issue that I had to deal with last month at one of our customers. This issue will probably not occur very often but it is a… 

How to rename an existing Fusion Middleware WebLogic Domain

Some times it happens that we need to rename an existing fusion Middleware WebLogic domain. I was asked to do such on a Fusion Middleware Reports & Forms environment. I took some time to check how this can be done and did some testing to confirm it works as expected. The difficulty is not the WebLogic Domain itself as a… 

WebLogic – SSO/Atn/Atz – How to enable debug logs

Let’s say that you have an application deployed on a WebLogic Server and that the SSO/Atn/Atz (SSO/Authentication/Authorization) isn’t working or throwing a 4xx error code like ‘401 – Unauthorized’ or ‘403 – Forbidden’. How would you be able to know what is happening and how to solve it? Well the answer is always the same: enable debug logs, it is… 

Documentum – DFC traces setup & investigation

When working with Documentum, you will most probably have to enable the DFC traces one day or another and then work with these traces to analyze them. The purpose of this blog is simply to show how the DFC traces can be enabled, which tools can be used to quickly process them and what are the limitations of such things.… 

Documentum xPlore: Tuning of JVM for high throughput and low CPU usage

Sometimes you have java processes or even jboss servers using a lot of CPU. In my example I had an xPlore dsearch server using like 98% of the cpu. When using jconsole and jvisualvm I figured out the garbage collector was using 50 to 60% of the cpu time. This was because the server was indexing and accessing the internal… 

Documentum xPlore: Several ways to start an Index Agent

In order to start index agents, you have several ways, depending on how you need to start them. 1. Use the documentum job dm_FTIndexAgentBoot. If you setup start_index_agents=T in the server.ini, the job will be called when the docbases are started. 2. Use the web interface: Login to http://server:9200/IndexAgent/ with docbase credentials and select “Start in normal mode” 3. Login… 

Documentum – Unable to stop an IDS configured in SSL?

When working with the IDS, you might face some interesting behaviors as mentioned in the last blog I wrote for example. This one will focus on the SSL part of the IDS on the target side. On this blog, I will start with showing the content of our start/stop scripts and how it is working in non-SSL, then switching to SSL… 

Documentum – Unable to configure IDS 7.3 for a docbase

In this blog, I will talk about an issue with the IDS 7.3 which is installed on a Content Server 7.3. The IDS is the Interactive Delivery Services. It is a product provided by OpenText that needs to be installed on a Content Server (for the “Source” part) and on a Target Server (for the “Target” part). The IDS can… 

Documentum – ActiveX error 12019 in D2-Config during export

Some months ago at a customer, we started the rollout of some security baselines on a new application (not yet productive). One of the changes was to enforce the use of TLSv1.2 on all our Documentum Clients like D2/D2-Config (4.5, 4.6, 4.7), DA (7.2, 7.3), aso… TLSv1.2 was already enabled before that but there was also a fallback to TLSv1.1… 

Enable Trusted Content Services (TCS) license in Documentum Content Server

The Trusted Content Services is a pack of features that you can enable/purchase to gain more security for your Content Server. The main key features are listed in this documentation: https://www.emc.com/collateral/software/data-sheet/h3138-security-ds.pdf In our case, we wanted to benefit from the Repository Encryption feature: Repository Encryption: Documentum TCS prevents intruders from accessing information even if they obtain unauthorized access to repository… 

New installed Fusion Middleware 12C Reports or Forms WebLogic Servers fails to start after configuring SSL

We installed a Fusion Middleware report and Forms 12.2.1.2.0 on a Linux Server. This was a single node Reports and Forms servers. After disabling the Non SSL Listen Port, we get below error in logs while starting the Managed Server with only SSL ports enabled. ####<Oct 27, 2017, 2:38:23,265 PM CEST> <Info> <Deployer> <host01.example.com> <WLS_FORMS> <[ACTIVE] ExecuteThread: ‘1’ for queue:…
