  • KnowledgeTree 3.7.0.2 Document Indexing and Indexer issues (SOLVED)

    Argh. Well, it’s really not quite out of the box, at least on Ubutu Server 9.10 (after reinstallations required after initial failures…), so this is just a selection of the fixes that made the import and indexing of the 160 000 files at 102GB possible. So for KnowledgeTree 3.7.0.2 Commercial Edition (the same holds true for the Community Edition), the following should help:

    1. Use the best-practice advice when doing the local file system import – rather do 10 000 files at a time rather than 100 000 at once. Really. Trust me. It defeats the whole idea of just running a batch job. Completely. As you’d expect the option of saying – just transfer all data in directory X. But alas, that doesn’t work. So do it in batches. Manually.
    2. Tika Apache Indexer for Lucene – not so much on PDFs, Docs, XLS or PPT files. Install catdoc (which includes catppt and xls2csv) and pdftotext (which you’ll find in xpdf-utils).
      1. apt-get install catdoc pdftotext
      2. modify knowledgetree/search2/indexing/extractors/TikaApacheExtractor.inc.php and comment out the mime types that are affected above from the returned array in getSupportedMimeTypes() – PDF, XLS, DOC and PPT: (more…)

  • KnowledgeTree 3.7.0.2 reinstallation site startup failure (SOLVED)

    OpenOffice.org startup failures, indexing issues and other niggles forced me to re-install KnowledgeTree 3.7.0.2 Commercial Edition (the same holds true for the Community Edition) more than once during setup. I was met with this delicious error notification which killed all further activity on the site (and prevented the startup of /setup/wizard/, control.php, browse.php, login.php — well, everything, really):

    Warning: include_once(DB/.php) [function.include-once]: failed to open stream: No such file or directory in /usr/share/knowledgetree/thirdparty/pear/DB.php on line 371

  • KnowledgeTree 3.7.0.2 – OpenOffice startup script (SOLVED)

    Having repeatedly received the error that OpenOffice.org is not running on the standard installation of KnowledgeTree 3.7.0.2 Commercial Edition (the same holds true for the Community Edition), further investigation was necessary. The key area of investigation must focus on the dmsctl.sh file, particularly from line 47 onwards, but more of that further down below. This is on Ubuntu (9.10 Server).

    First, do a few quick checks:

    1. Is the process running? Anywhere?
      Check whether OpenOffice.org is actually running, using a simple netstat -pant| grep 8100 — as the default installation is running with a headless OpenOffice.org on port 8100. You should see something like:

      tcp  0 0 127.0.0.1:8100 0.0.0.0:*  LISTEN  9655/soffice.bin

      For the fix in question, it wasn’t giving any results on this check (sudo the commands where required, but you knew that already), which means that it’s not running properly. Also,

      ps -aux | grep soffice

      gave no results, indicating non-functioning backend software.

  • Knowledge Tree 3.7 Community Edition released

    PBGVVH25US66 They released the Knowledge Tree 3.7 RC Community Edition some time ago, which now runs on the full Zend-Server stack! Infrastructurally, this is the biggest changed; PHP-based setup wizards also feature, and sure – you can now run it on IIS6/IIS7, but that switch to the Zend stack with use of Optimiser features most highly for me on this development. But you knew that already! 🙂

    Curious to see the feedback from Steve Briggs from iBurst about their KnowledgeTree (not necessarily their whole CRM solution) usage and implementation experience at iBurst, after the chat I had with him yesterday…
