Managing documents and working together in the digital workplace: Documentum, M-Files, Alfresco, SharePoint, Microsoft Teams and web platforms. Our consultants write about content management, collaboration, integration and the compliance questions that come with them.
At some of our customers, we often install new docbases for development purposes which are used only for a short time to avoid cross-team interactions/interferences and this kind of things. Creating new docbases is quite easy with Documentum but it still takes some time (unless you use silent installations or Docker components). Therefore installing/removing docbases over and over can be a…
In Documentum, there is a parameter named concurrent_sessions which basically defines how many sessions a Content Server can open simultaneously. This parameter is defined in the server.ini file (or server_<dm_server_config.object_name>.ini on a Remote Content Server) of each docbase and it has a default value of 100. An empty Content Server with an IndexAgent and D2 installed (without user using it)…
If you are familiar with Documentum or if you already read some of my blogs, then you probably already know that EMC has sometimes issues with libraries. In a previous blog (this one), I talked about the Lockbox versions which caused us an issue and in this blog, I will talk about DFC versions. Whenever you install a CS patch…
A few months ago and right after a migration of around 0.5TB of documents, we enabled the TCS for one of our Application. We were using a Content Server 7.2 P05 with the associated D2 4.5 P03. As already mentioned in a previous blog, D2 4.5 doesn’t handle the previews of the documents and therefore there were also a Thumbnail…
We had a problem with a customer where D2 was not loading properly in IE when going through F5 (load balancer). When trying to access D2 through the F5, let’s say: https://d2prod/D2 only a few menus and some part of the workspace were loading but it ended to say “Unexpected error occured”. Investigation It would have been too easy if…
WebLogicServer takes a long time (e.g. over 15 minutes) to startup. Can the performance be improved? Using /dev/urandom option in the Weblogic Java Virtual Machine parameters from startup script, can be the solution. In fact, /dev/random is a blocking device and during times of low entropy (when there is not enough random bits left in it), /dev/random will block any…
After upgrading from 6.7.x to 7.2, the following warning message is logged in JMS log files: com.documentum.fc.common.DfNewInterprocessLockImpl – [DFC_FILE_LOCK_ACQUIRE_WARN] Failed to acquire lock proceeding ahead with no lock java.nio.channels.OverlappingFileLockException at sun.nio.ch.SharedFileLockTable.checkList FileLockTable.java:255) By default ACS and ServerApp dfc.properties are pointing to $DOCUMENTUM_SHARED/config/dfc.properties. Adding separate ‘dfc.data.dir’ cache folder location in ACS and ServerApp dfc.properties. After JAVA Method Server restart, two separate…
When installing a new Remote Content Server (High Availability), everything was going according to the plan until we try to login to DA using this new CS: the login using the Installation Owner (dmadmin) failed… Same result from dqMan or any other third party tools and only the iapi or idql sessions on the Content Server itself were still working…
At one of our customer, we were in the middle of a migration process of some docbases from 6.7 to 7.2. A few days after the migration, we started seeing some failures/errors during simple download of documents from D2 4.5. The migration has been done using the EMC EMA migration tool by some EMC colleagues. The strange thing here is…
A few weeks ago at a customer, I was installing a completely new sandbox environment for one of our Application Teams. On this environment, we used a new version stack with the most recent patch set (at that time): CS 7.2 P16, D2 4.6 P05, aso… A new patch level means a lot of “fun” trying to install and execute…
As already explained in this blog, we had to remove the PDF renditions for a customer to only keep the jpeg renditions on the ADTS side because the PDF was generated by another third-party tool. If you take a look at the dmr_content items attached to a specific document (parent_id), you will understand that there is by default only one…
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…
