[Mulgara-dev] XAFix Impl notes

[David Moll]

I just wanted to update on some of the testing that I have been doing
with the XAFix implementation.  It works very well, and I have not been
able to find any showstopping issues for us.

 

I'm running Mulgara on a Win2k3 Server (still, I know) with Dual Xeon
3.2 GHz Dual-Core processors and 4 GB of RAM.  I'm using the 64-bit
1.5.0_09 JVM, and invoking Mulgara with:

 

java -jar mulgara-1.0.0.jar -l "file:/F:/Program Files
(x86)/mulgara-1.0.0/log4j-conf.xml" -k 192.168.10.205 -o 192.168.10.205

 

We currently have around 11.6 million triples in the datastore.  For my
testing I have a text file with ~1800 itql queries in it.  We have a
.NET application that uses the SOAP interface to query Mulgara.  I point
the app at a directory and it executes all the queries stored in the
files in that directory.  Prior to the XAFix implementation I could
really only run one instance of this at a time.  Now, I have run as many
as 6 separate instances, all executing queries against the data store
without any exceptions being thrown.

 

Memory usage seems to have improved as well.  I left the queries running
(cycling) for about 6 days, and the peak memory usage barely broke 1 GB.
Of course, there is the question of how accurate the Windows Task
Manager is.

 

I'm looking in to figuring out the information for the "Update Patterns"
information.
