Determine remote server version.
by Huib Verwey 20 May '11

20 May '11

Hi all, I'm trying to determine the BaseX version running a remote server. When I connect using the client on my local machine the server does not say which version it is When I use the GUI to connect to the remote server I can't find any info on the version. When I login to the remote machine and go to the server folder I can't find any info on which version it is. When I look at the logs in the .logs folder I can't find any info on the server version (I could not find the startup info that the server generates). I copied the BaseX.jar to a place where I could unpack it and found version "6.6" in the META-INF/maven/org.basex/basex/pom.xml file. Is there a more convenient way of determining the remote version that I missed? And did I actually find the correct version in the pom? Hartelijke groet, Huib Verweij. P.S. In the BaseX GUI the "Logs" tab shows me the logs of the local BaseX even when I connect to a remote BaseX - could be on puprpose, I just found it somewhat counter intuitive.

Re: [basex-talk] Renaming of documents
by Leo Wörteler 18 May '11

Hi Thomas, I could reproduce the bug and we'll fix it soon. Your query however looks a bit strange to me: Am 21.04.2011 14:31, schrieb Thomas Kaltofen: > insert node collection('db/docb')/rootB > after collection('db/doca')/rootA Your collection looks something like this: > collection(db) > | > |-- document(doca) > | | > | `-- <rootA .../> > | > `-- document(docb) > | > `-- <rootB .../> Your query doesn't create a new document node (as XQuery Update doesn't operate on document level) but inserts the <rootB .../> element directly into the first document, which then has two(!) root elements: > collection(db) > | > |-- document(doca) > | | > | |-- <rootA .../> > | | > | `-- <rootB .../> > [...] That's allowed in XQuery Update, but isn't valid XML any more and I can't think of a scenario where it's actually desirable. Is that what you wanted to do? If not, could you explain in more detail what you intended? Cheers Leo

Re: [basex-talk] BaseXServer.bat not respecting the -c"SET DBPATH ..." option?
by Jason Klassen 17 May '11

17 May '11

Hi Christian, Using 6.6.3 does solve the default directory creation but it still does not respect the SET DBPATH for execution. What I also noticed was that after I start the basexserver I can change the .basex file on the fly and the clientsession in the app will then reflect that change. So something still seems to give the .basex dbpath value precedence. Interestingly the logs are recording and locked using the directory from -c"SET DBPATH..." even when I change the .basex file. Here's the command I was using to start it up. Makes no difference if I replace basex-6.6.3-SNAPSHOT.jar in the basexserver.bat either. C:\BaseX\bin>java -cp C:\basex\basex-6.6.3-SNAPSHOT.jar org.basex.BaseXServer -p1985 -c"SET DBPATH C:/BaseX/BaseXData;info" General Information Database Path: C:/BaseX/BaseXData Used Main Memory: 1129 KB Database Creation Whitespace Chopping: ON Entity Parsing: OFF Indexes Path Summary: ON Text Index: ON Attribute Index: ON Full-Text Index: OFF BaseX 6.6.3 beta [Server] Server was started. Jason -----Original Message----- From: Christian Grün [mailto:christian.gruen@uni-konstanz.de] Sent: May-17-11 3:54 AM To: Jennifer Violago; Jason Klassen Subject: Re: [basex-talk] BaseXServer.bat not respecting the -c"SET DBPATH ..." option? Dear Jason, I had a quick look into the code base; the commands (specified by -c) were executed after having initialized the server instance. As a consequence, the default database directory was created before parsing the DBPATH option. I decided to switch the execution order: the specified commands will now be executed before initializing the logger (which is responsible for creating the database/.logs directory, and locking that folder). Feel free to give us some feedback on the latest 6.6.3 snapshot of BaseX (which is as stable as the official release): http://files.basex.org/releases/latest/ Hope this helps, Christian

BaseX Vorstellung beim inf.misc Treffen?
by Thomas Koch 17 May '11

17 May '11

Hallo, an der Uni Konstanz gibt es ganz frisch eine neue Vortragsreihe: https://www.fachschaft.inf.uni-konstanz.de/inf.misc Ich habe heute gesehen, dass basex sogar im Debian Archiv aufgeschlagen ist. Hätte nicht jemand Lust, das Projekt an einem Donnerstagabend vorzustellen? Beste Grüße, Thomas Koch, http://www.koch.ro

BaseXServer.bat not respecting the -c"SET DBPATH ..." option?
by Jason Klassen 16 May '11

16 May '11

I'm trying to run a BaseX Server and have it read data from a different directory than the default. So I add the flag -c"SET DBPATH C:/Working/BaseXData;info". To make sure that no previous settings are corrupting it I renamed the old .basex file to something else so it wouldn't find it. The info shows me the Database Path is correct. C:\Working>C:\basex\bin\basexserver -p1985 -c"SET DBPATH C:/Working/BaseXData;info" Saving properties in "C:\Users\jklassen/.basex"... BaseX 6.6 [Server] Server was started. General Information Database Path: C:/Working/BaseXData Used Main Memory: 1154 KB Database Creation Whitespace Chopping: ON Entity Parsing: OFF Indexes Path Summary: ON Text Index: ON Attribute Index: ON Full-Text Index: OFF Upon running basexserver a new .basex file is created. The contents of my .basex file are # Property File. # You can set additional options at the end of the file. DBPATH = C:\Users\jklassen/BaseXData JAXRXPATH = C:\Users\jklassen/BaseXWeb LANG = English LANGKEYS = false HOST = localhost PORT = 1984 SERVERPORT = 1984 JAXRXPORT = 8984 TIMEOUT = 0 # User defined section You can see that it created the file using the default windows directory. (I'm on windows 7). I would be fine with it except for the fact that no matter what I specify in SET DBPATH the server is only accessing the default C:\Users\jklassen/BaseXData folder. It does correctly initiate on the 1985 port. If I change the file to read # Property File. # You can set additional options at the end of the file. DBPATH = C:/Working/BaseXData JAXRXPATH = C:\Users\jklassen/BaseXWeb LANG = English LANGKEYS = false HOST = localhost PORT = 1984 SERVERPORT = 1984 JAXRXPORT = 8984 TIMEOUT = 0 # User defined section It works and finds the data in the right directory. If I add the flag -c"SET DBPATH C:/FakeDirectory/BaseXData;info" it still works, even though the info shows the new database path, leading me to believe it's ignoring the command. The problem for me lies in the fact that I want two BaseX Servers running on the same machine. One on port 1984 for my backend app and one on port 1985 for my web app and I'd like them to use separate file directories. Is SET DBPATH the right way to accomplish this? ________________________________ Jason Klassen Protegra Business. Technology. Solutions.
