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.
I went into an error that you might already have once, so here is a quick guide on how to fix it. When deleting a document from D2 I had a popup with an error like: Cannot delete file because it is still referenced in a virtual document or an assembly. Well indeed the document that I wanted to delete…
I’ve been patching around some xPlore servers for a while and recently I went into an issue regarding the ftintegrity tool. Maybe you figured it out as well, for xPlore 1.5 Patch 15 the ftintegrity tool available in $DSEARCH_HOME/setup/indexagent/tools was corrupted by the patch. I think for some reason the libs were changed and the tool wasn’t able to load…
The Load Balancers do not provide the client IP address by default. The WebLogic HTTP log file (access_log) does not provide the client IP address but the Load Balancer one. This is sometimes a problem when diagnosing issues and the Single Sign On configuration does not provide the user name in the HTTP log either. In most of the cases,…
I’m quite used to GitHub since I’m using it pretty often but I actually never tried to use it behind a proxy. In the last months, I was working on a project and I had to use GitHub to version control the repository that contained scripts, monitoring configurations, aso… When setting up my local workstation (Windows) using the GUI, I…
Introduction In one of my missions, I was requested to run performance and load tests on a ADF application running in a Oracle Fusion Middleware environment protected using Oracle Access Manager. For this task we decided to use Apache JMeter because it provides the control needed on the tests and uses multiple threads to emulate multiple users. It can be…
One of my last mission was to configure Apache JMeter for performance and load tests on a Web Application. The access to this Web Application requires authentication provided by a Microsoft Advanced Directory Federation Services single Sign On environment. This Single Sign On communication is based on SAML (Security Assertion Markup Language). SAML is an XML-based open standard data format…
Today at one of our GoldenGate customers we were faced with the following requirement: For one of the tables on the target we needed two additional columns which shall hold the insert and update timestamps for when the row was either inserted or updated. Just to be clear: It was not about getting the timestamps for the inserts or updates…
Maybe you had some issues with UCF in DA as me. I had this for no reason since few days at a customer. The problem was that we use SSL with DA and the Unified Content Facilities (UCF) wasn’t happy about it. Thus, in this short blog I’ll speak about troubleshooting UCF. The error I got happened when trying to…
As part of my previous posts about having 2 rendition servers for one docbase (see below), I’ll show you how to simply switch a rendition queue item to the other server – http://dbi-services.com/blog/documentum-multiple-adts-ratio-of-rendition-creations-between-instances-part-1/ – http://dbi-services.com/blog/documentum-multiple-adts-ratio-of-rendition-creations-between-instances-part-2/ I had an issue by a customer where one of the two rendition server was stuck since 2 days. As I explained in my previous…
I had this strange behavior that once upgraded from 6.7 to 7.2 a new ACS was created. I think it’s because the current ACS name didn’t fit the new ACS name pattern. Well it’s not a big issue to have 2 ACS configured. But in my case they pointed both to the same port and servlet so… I had to…
In this blog, we will cover all steps to enable SSL encryption for a particular server. The procedure described here applies mostly for Java based servers and applications, with usage of a keystore. In the case the organization into which the certificate has to be deployed has its own PKI, usage of OpenSSL is not necessary. In this case Java…
In this blog, I will talk about the setup of an Apache httpd server with/without SSL configuration on top of your Alfresco installation. This way of configuring Apache httpd in front of your Web Application can be reused very easily for all other applications like your intranet, competency center, resource planning, aso… It is NOT specific to Alfresco and this…
