[MonetDB-users] Concurrent user threads
by Vashti_Ragoonath＠ibi.com 10 Dec '09

Hi, I read in the SQL Reference Manual that "The number of concurrent user threads is a configuration parameter.", but no information on the name or location or how to change it. Nor is there any info on what the default might be. I tried running multiple users and noticed that the performance degradation increased dramatically as the load increased. I looked at the Server and SQL manuals without luck. Thanks, Tah

[MonetDB-users] file system usage
by Matthew Jones 10 Dec '09

Hey folks, I'm wondering if you can tell me how MonetDB manages its on-disk database. During normal operation I was seeing the database hovering at around 55G, after I stopped it to take a backup it was at 70G, but immediately after the restart it dropped down to 35G. 73, Matthew W.

[MonetDB-users] lib_replication

Hi, I was able to load up and run the MonetDB5-SQL-Installer-x86_64-20091023.msi. However, when I tried the MonetDB5-SQL-Installer-x86_64-20091119.msi I received an error about the server failing to start because it could not find lib_replication.dll. There is no indication in the Readme.html that this has to be built and it's not in the 1119 package. I tried using the 1119 because I created some compressed files (gz files created with gzip) that I wanted to load using COPY INTO and read that this is supported on Windows in the 1119 version. In the 1123 version it generated an error when loading the GZ files about not being able to locate the files - a bogus error it seems since the file path was correct. I looked on Google, forums etc but no other reports. I reloaded the 1123 to make sure that was still working and it is. I hope I did not miss a basic step or something in which case I apologize profusely! Thanks, Tah
