November 23

Yesterday my Comodo Firewall (version 2.4) alerted me that there was a new update for the software. Until know I was very happy with this free (lifetime) software package, until I updated the software…

It upgraded itself to Comodo Firewall Pro 3 (firewall software PLUS new intrusion detection software). Great I thought and during installation it asked if I wanted to set it to, for instance “learning” mode. I liked this in the former version, so I did it again. After a reboot, hell broke loose.

This is a bummer and then again it is not. I am thinking lately a lot about how to bring the conceptual XML(DB) world into the Oracle Relational world, or in other words “what is needed to make XML fast – given an Oracle database 11g atmosphere”. One my ramblings was: OK given the XML free format, how do I a create an environment that’s very high selective based on indexing and or breaking up XML fragments in physical segments (therefore hopefully being more selective) that can be handled more easily by the Oracle Optimizer (even given items like, creation solutions for, XML deficiencies like data redundancy etc).

Anyway…

Searching the internet I came up with this excellent (it helped me one step further in my exploring brain matter path) link regarding indexing called:

What’s more, and this brings me back awfully close to home (Holland / Amsterdam), I looked up the used references by Shweta Agrawal. One of them was called:

Little bit cynical or not?

Anyway after downloading Oracle VM Server 2.1, unzipping it, it was installed in a breeze. It is delivered as a ISO so I mounted the ISO under the CD ROM of a VMware guest, configured as described below. The guest I used was a VMware Server guest based on RedHat 4 (32b).

So I used the following:

  • RedHat Enterprise Linux 4 host (32b)
  • 1.5 Gb RAM
  • 20 Gb extensible HD
  • Network: NAT
  • 1 CPU
