TSG’s work with the New York Philharmonic Digital Archives was recently named 2012 Alfresco Implementation of the Year.  We wanted to thank the team at the NY Philharmonic for giving TSG the opportunity to work with them and providing the vision of what the Digital Archives is today.  The digital archives provides a perfect example of how open source technologies can be leveraged to create a robust and scalable enterprise solution.  Using OpenMigrate for high volume content ingestion, OpenAnnotate for face tagging, Solr for faceted search, with Alfresco as the central repository make up the key architectural components driving its success.  We look forward to continue working with the New York Philharmonic as they innovate and expand the digital archives.

I was talking to a client last week that was struggling with their Documentum system performance.  This client had recently brought in Documentum Consulting, and having been unsuccessful in improving performance, was concerned that there might be nothing left to do.  This post will focus on innovative things TSG has done for clients in regards to Documentum performance that are probably outside of the norm of typical database/server tuning particularly focused on Search, Document Retrieval and Inbox viewing.

Virtual Momentum Lisbon 2010 and Midwest Documentum User Group

Published October 27, 2010 Documentum , Lucene , MyDocumentum , Search , SharePoint , xCP 2 Comments

One last reminder – Midwest Documentum User Group (MWDUG) is coming up this Friday, October 29th, in downtown Chicago – presentations will include American Electric Power, United Airlines, Documentum Roadmap as well as others.  There are still spots open if you are interested in attending.  http://www.mwdug.com

As we were talking to users outside of the Chicago area about MWDUG, it isn’t hard to see that travel is still being restricted during the downturn (or post-downturn).  Obviously, not many of us could travel to Lisbon, Portugal for Momentum 2010 this month.   One thing unique this year is that
EMC/Documentum has opened up the ability to attend Momentum virtually.  Slide decks and presentations will be posted next week and available virtually for only $200 – signup is here – Virtual Momentum.

Documentum 6.5 Upgrade – Character Encoding Issues

Published August 26, 2010 D6 , D6.5 , Documentum , HPI , Lucene , Migrations , Open Source , OpenMigrate , Tech Tip , Upgrades , Webtop 4 Comments

Special Note:  Anyone that is planning an upgrade from Documentum 5.3 to 6.5 should look closely at this note as some types of upgrades (clone or in-place) could result in content that was retrievable from 5.3 not being available in 6.5.

This post was developed based on recent work for a major pharmaceutical client.  The client, on Documentum 5.3, was developing a consumer interface application leveraging Lucene.  As we mentioned in a previous post, the client chose Lucene over FAST based on benchmarking results for over 150,000 documents.

Background

For the application, the client was leveraging OpenMigrate with DFC 6.5 to retrieve content and metadata for nearly 1,000,000 documents from their 5.3 docbase to be indexed in Lucene.  Per the product release notes, using DFC 6.5 to access a 5.3 repository is a supported configuration.  An issue was identified when around 5,000 documents failed to migrate.  In reviewing the error logs from OpenMigrate, the DFC call IDfSession.getObject() to retrieve documents from the repository resulted in errors.  After reviewing the stack trace, it was apparent that the error was being thrown from within the DFC code.  The team was surprised by the error since the documents were able to be retrieved without a problem using client applications working with a 5.3 DFC, such as Webtop and Samson.  The DFC error messages that were encountered are shown below:
