- Alfresco: some useful database queries – Blog dbi services – In my previous post, I talked about the Lifecycle of Alfresco Nodes. You may have noticed that I tried to insert in my explanations some elements that are specific to databases (tables, fields, aso…). These elements are quite essential to prepare a post like this one: more database oriented. I already explained what exactly are the consequences on the database side when a node is removed and I will try in this post to share some useful queries regarding these points but not only! For this post, I used my local Alfresco Community 4.2.c installation with a PostgreSQL database. For your information, it just take 30 minutes to get this test environment ready with the Alfresco’s installer (Windows, Mac or Unix). Of course, use the Database only for your daily administration work is certainly not the best idea but in some cases, it can really be faster and easier to just run some SQL commands at the DB level…

- Shrinkpdf – A simple wrapper around Ghostscript to shrink PDFs (as in reduce filesize) under Linux. Inspired by some code I found in an OpenOffice Python script (I think). The script feeds a PDF through Ghostscript, which performs lossy recompression by such methods as downsampling the images to 72dpi. The result should be (but not always is) a much smaller file

- Disaster: LVM Performance in Snapshot Mode – MySQL Performance Blog – In many cases I speculate how things should work based on what they do and in number of cases this lead me forming too good impression about technology and when running in completely unanticipated bug or performance bottleneck. This is exactly the case with LVM
Number of customers have reported the LVM gives very high penalty when snapshots are enabled (leave along if you try to run backup at this time) and so I decided to look into it.
- Netexpertise » Mysql Ultra-Fast Backup with LVM – It is generally good practice to respect the two following points when backing up databases. The backup has to be:
Consistency is easily achieved putting a read lock on all tables beforehands. However, this isn’t always applied, and WILL definately lead to a database integrity problem at some stage.
Once a lock has been set on the database, the backup has to be as quick as possible, all write instructions being held in the queue.
