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 have seen several times in the past duplicate JMS and/or ACS objects created by OpenText (and Dell/EMC before) installers. I opened several tickets with the OpenText Support over the past 4/5 years to try to get a reason and a fix (had the issue with all versions, 7.1, 7.2, 7.3, 16.4). The first few tickets (2 or 3, I…
A couple months ago, I was working on an upgrade project from Documentum 7.x to 16.4. During this upgrade, I faced a few issues so I will try to write some blogs about all that in the coming weeks, starting today with an alleged “corrupt” Lockbox. This upgrade was part of a migration as well from Virtual Machines to Containers…
While working with xPlore, you might have faced before a message saying that an xPlore installer refused to start because it is not allowed to run multiple instances at the same time. This could have happened while running any installer: binaries, patches, dsearch, aso… However, when checking the processes, there is only one running and that’s the one you just…
In some specific cases, you might have faced an issue where Documentum Administrator is loading properly but then suddenly it’s not working anymore and all you did in between was accessing D2. I don’t remember seeing that before DA 16.x but maybe it’s just my memory that is playing me tricks! When this happen, you will see the usual pop-up…
Earlier today, I talked about the Export/Download that wasn’t working randomly. In the end, it was both linked to the wsctf browser plugin (that didn’t provide the necessary cookies in the download request) as well as the “loadBalancedContentServer” parameter (that was wrongly set to false). For the previous issue, setting the “loadBalancedContentServer” property to true was sufficient to solve it…
The D2 clients were, until recently (D2 version 16.4 included), working by default with the java plugin mode and therefore, many actions were using a JVM on the client workstation. This setting can be controlled/set in the “WEB-INF/classes/settings.properties” file of D2 applications (D2, D2-REST, D2-Smartview) and the default value was therefore “browser.plugin.mode = java“. Starting with D2 16.5, this was…
As you probably know, Documentum introduced the optional use of a Lockbox since version 7. It was done initially to contribute to the security of the AEK key which is one of the central components of a Content Server. Time showed that, well, it’s not so easy and since then, nothing much changed on the Lockbox layer. With the version…
Recently in a project, one of the Documentum environments we were working on started showing failure on the execution of the dm_DMFilescan job and only this one. After a couple minutes of investigation, I quickly found the root cause of the issue which wasn’t very important, but I thought I would share it because of the implications it has. In…
As discussed in a previous blog, working with LSS might prove a little bit challenging from time to time. In this blog, I wanted to share an error I saw while installing LSS 16.6.1 on an Oracle database. Initially, I developed my silent installation for LSS (while encapsulate the LSS silent scripts provided by OpenText) using a PostgreSQL database because…
D2-Smartview is a new UI that OpenText now provides starting with the version 16 of D2. It’s a lightweight UI that can perform some of the actions that D2 does. The list of features will probably increase with time but at the moment, I guess it’s more for simple users that have very basic needs, consumer like roles mainly. An…
A few months ago, I was working on automating an LSS installation for a customer so I thought about sharing my experience around that topic… LSS is the Life Sciences product from OpenText (formerly EMC->Dell->OpenText). It can be split into four sub-products, which can be installed independently or all together, depending on the needs. These four products are the LSTMF…
During some monitoring work on a WebLogic 12.1.3 environment, I noticed that top shows the process 12013 using 800% CPU (We have a 12 CPU machine) and had to find out what’s happening !!
