Fwd: BaseX Server
by Christian Grün 13 Dec '12

Hi all, attached is some interesting information from Raymond Meester on how to get BaseX running as Windows service. Everyone’s feedback is welcome, Christian ---------- Forwarded message ---------- From: Raymond Meester <raymondmeester(a)gmail.com> Hi Christian, A small update on implementing basex. Still working on the issue that BaseXServer suddenly isn't available more (started as BaseXServer -S on a Windows 2008 r2 server). I tried to monitor the process with procmon, unfortunaly due to a leak procmon flooded the page file of the server. So I had to go for another approach. As our administrator are familiar with windows services I tried to install basex as windows service. - First I tried the Java launcher Janel (http://www.redskaper.com/), but I could get it working. Don't know why, but it seemed to be a Janel issue. - Secondly I tried another Java launcher (http://winrun4j.sourceforge.net/). With this launcher I was able to got a working executable. I attached the ini file I used. However to use it as a windows service it needs a java method to work with services (see "Service example" on their webpage). - Last I used the working exe and this manual http://marckean.wordpress.com/2009/05/24/run-shoutcast-as-a-windows-service/ ((I attached the tools which the manual uses: instrv.exe and srvany.exe. (I changed the extension to .txt to get them through the email scanner. I believe they are part of the tool "resource hacker" http://www.angusj.com/resourcehacker/) And now I got BaseX running as a windows service. So of course I would like to see a native way to install Basex as Windows Service, but I thought I let you know how I manage this. Also when there is a better way (not changing the registry directly), please put it on the wiki. Regards, Raymond

I think I have found my problem. I post this here in case it helps anyone else. The java date constructor is initialized with a long, my attempts use a literal are what caused it to fail. I cast my literal as a long xs:long("133554732") and it worked, though not perfectly because epoch is in seconds and java is milliseconds. Thus I had to multiply my literal by 1000 first and then cast it as a long let $fdate: =133554732*1000 let $edat := dt:new(xs:long($fdate)) I then can access the TimeZone.IsDaylightTime property Thanks to Christian for his help on this.

Re: [basex-talk] BaseX in Farsi?
by Masoumeh Seydi Gheranghiyeh 12 Dec '12

Hi Christian That would be a great idea. I am really interested in. Supporting Persian language makes support of the other right-to-left languages, like Arabic and Hebrew, also possible. As you've said, the first step is to find out how much effort is needed to add the right-to-left format to the editor. I will take a look at it to investigate how to do it and highly appreciate any suggestion.

Problems DST

Hi All, I wrote a xquery in Basex that created an xml file that calculated student grades. Points are dependent on students doing an activity in a window which ends at midnight on sunday each week. The date/time of the activities are stored in the source file in UTC. However, to know if they met the deadline, I need it in local time. I do this by creating a function that translates epoch to a regulate dateTime variable. But I see that when we left daylight savings time, things were thrown off by an hour. The command I use is: adjust-dateTime-to-timezone((xs:dateTime("1970-01-01T00:00:00-00:00") + xs:dayTimeDuration(concat("PT", $v, "S"))),xs:dayTimeDuration('-PT4H')) clearly the problem is the last part -PT4H, because dates that fall after the switch back to standard time from daylight savings time should be -PT5H. Is there a better way of doing this? Is there another command that will give me a localized date that takes into account daylight savings time issues? I tried to set a java calendar but I could not make it work. Any help would be gratefully appreciated. Thanks in advance Randy -- Dr. Randall Reed Assistant Professor, Dept. of Philosophy and Religion Appalachian State University

Are command scripts optimized before execution? / Optimization of my query
by Ben Companjen 10 Dec '12

10 Dec '12

Hi all, I was wondering whether command scripts are optimized before they are executed. I would think so, because when I had made an error in the, say, sixth command in my script, it was caught before the first command was executed. But more importantly for my application: it seems that combinations of "CLOSE; OPEN <same DB as just closed>" are skipped. I created an XQuery to copy 680000 records from my XML DB to MySQL. These records are MODS, found inside record elements at XPath /file/record. The database is about 2.5 GB and eats even more of my main memory when I try to copy all records in one run. I found out that doing subsequences of 50000 to 10000 records speeds up the process significantly and the server uses a lot less memory. For instance, when I start processing records from 400001, BaseX apparently doesn't keep the first 400000 in memory. But just doing 50000 records in a row, shifting the begin parameter of the subsequence and going on, eventually slows the process from tens to more than 100 records per second to less than one per second, probably because memory consumption goes up to all available memory (I assigned 3 GB to the JVM at startup of the server). Therefore I tried to free some memory by closing the database, re-opening it and then resume processing. But I don't see the memory usage reduction that I hoped for. >From my XQuery mods2sql5.xq: <namespace declarations> declare variable $begin as xs:integer external := 1; declare variable $length as xs:integer external := 50000; <function declarations: prepare statement return sql:execute-prepared(...)> (: main process :) for $record at $rodb in subsequence(/file/record[mods:mods][@id != ""], $begin, $length) <call functions to process records> return <functions' output as sequence> >From my command script mods2sql.bxs: SET QUERYINFO true OPEN monly2 SET BINDINGS $begin=1,$length=50000 RUN /Users/ben/Documents/xquery/metadata_only/mods2sql5.xq SET BINDINGS $begin=50001 RUN /Users/ben/Documents/xquery/metadata_only/mods2sql5.xq CLOSE OPEN monly2 SET BINDINGS $begin=100001 RUN /Users/ben/Documents/xquery/metadata_only/mods2sql5.xq SET BINDINGS $begin=150001 RUN /Users/ben/Documents/xquery/metadata_only/mods2sql5.xq SET BINDINGS $begin=200001 RUN /Users/ben/Documents/xquery/metadata_only/mods2sql5.xq CLOSE OPEN monly2 ... Are my observations about optimizations of command scripts correct? Is there any way to speed up my process? Thanks for any advice! Regards, Ben

UPDINDEX fails; command basexserver does not work
by Mahlow Cerstin 10 Dec '12

10 Dec '12

Hi, I just encountered two problems: I'm using a collection created wit UPDINDEX TRUE using BaseX75-20121114. When I tested it, everything worked fine, the index was recreated each time I stored or deleted something. However, today one of the users really worked with the whole webapplication and after half an hour (searching two collections, storing some new nodes and updating some nodes), she got a server time out. In the GUI I could see, that the value of INDEX for "up-to-date" was "false". Which obviously caused the time out. But what could be the reason the index wasn't up to date anymore? How can I make sure the option is working as intended? Anyway, I decided to get the latest snapshot BaseX75-20121204 and re-create the collection with again setting UPDINDEX TRUE. For the webapplication I have a Linux server: Linux version 2.6.18-274.el5 (mockbuild(a)builder10.centos.org) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-50)) #1 SMP Fri Jul 22 04:43:29 EDT 2011 with java version "1.6.0_07" Java(TM) SE Runtime Environment (build 1.6.0_07-b06) Java HotSpot(TM) 64-Bit Server VM (build 10.0-b23, mixed mode) For development, I use a Mac with OSX 10.6.8. with java version "1.6.0_37" Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-10M3909) Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode) So I installed the latest snapshot on both and then tried to stop and restart the server. Which worked as usually fine on the Mac, but on the Linux server, when calling basexserver stop nothing happens. It looks like the script is waiting for some input -- the process does not stop. The old BaseX server seems to be running somehow; I cannot start the server either. Is this a known issue with the latest version? How can I force basexserver to stop and then restart it again?
