Hi team,
I have a couple of small questions and remarks:
- mclient timer doesn't work when running mclient with -s option.
[lafanasi@zookst4 stats]$ mclient -t -lx -s "count(doc('xmark01.xml'))" 1 [lafanasi@zookst4 stats]$ mclient -lx -t q1.xq 1 Timer 5.606 msec
Confirmed. Could you please file a bug report about this?
- does mclient option -I (capital i) work? For example, the following
command doesn't execute in 1 min. [lafanasi@zookst4 stats]$ mclient -lx -I xmark01.xml -s "count(.)"
`mclient --help` says
======== XQuery specific options -C colname | --collection=colname collection name -I docname | --input=docname document name, XML document on standard input ========
i.e., you mclient waits for the document to appear on standard input ;-) You probably mean to do something like
cat xmark01.xml | mclient -lx -I xmark01.xml -s "count(.)" or mclient -lx -I xmark01.xml -s "count(.)" < xmark01.xml
In fact, I don't know whether -I works in combination with -s; hence, the alternative is
mclient -lx -I xmark01.xml < xmark01.xml mclient -lx -s 'count(doc("xmark01.xml"))'
- Recently I couldn't access my db created with the latest release after
recompilation from HEAD. Do I need to back-up my db (by dumping the tables) when I recompile a new version from HEAD? A new release?
WhicH version was your DB created with? The last stable release (Jun2008 or Aug2008)? If so, you indeed have to dump your DB *with that version* *before* upgrading to the HEAD (or better the "soon" to be announce new Stable "Nov2008" release), and the reload the dump after upgrading. Like between the Feb2008 and Jun2008 releases (cf., http://monetdb.cwi.nl/Development/Releases/Version4.24/), we again had to change the physical database format since the Jun2008 release --- development for improvements never stops ;-)
- Mserver crushes on XMark of 11GB (-f 100). The query is: "find the maximum
length of the root to leaf paths, i.e., the tree depth". My specs: Linux zookst4 2.6.24.3-50.fc8 #1 SMP Thu Mar 20 13:39:08 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux, Mem 19GB. Do you have any tips on how to make it run?
How does it crash? Any error messages? How big does Mserver grow before crashing? What exactly does you query look like in XQuery? How did you configure & compile MonetDB? Which version of MonetDB do you use? Did you try both the algebra and the milprint_summer back-end / Pathfinder compiler?
