Re: [basex-talk] Looks like...

Hi Scoobs, unless you already know a lot about XML, XPath & XQuery (and just didn't use java much so far), i think BaseX might be a little overkill for your use-case. I would recommend an App like Gnome Contacts (allows creation of custom fields for grad dates, courses and freeform notes) for your contacts database, this would be more "fast-and-dirty" and wouldn't require you to "learn new tricks"...

Hi Scoobbs, you are perfectly right, the basex available on ubuntu repository is quite old. But, your mail smells (bad) ! Basex team is responsible on developing basex, and not on publishing packages for all OS, as explained by Dirk Kirsten. You can't fight again BaseX team if the actual packaging do not meet your requirements. BaseX distribute a package that can be fully installed on a complex environment in a very easy way - very easy. You just have to read the documentation to install BaseX on your Ubuntu server. For me, to install 8.2.3, it took exactly 12 minutes to make basex to run perfectly. If you don't understand the documentation, and still have problems to install, all list-users will be happy to help you. You could also think to a bit of sponsoring, it could help to produce a package for Ubuntu, during august, which is vacation-time for the whole north hemisphere. Please, be a little more respectful of other's work. Best regards, Christophe - which is not part of BaseX team.

Same XQuery faster 2nd+ time
by Philipp Steiner 21 Aug '15

21 Aug '15

Hi, i'm a student learning XPath/XQuery/BaseX and currently experiment with XQueries on large xml files in BaseX, hope i didn't miss something obvious :) Test: 1st FLOWR query on collection: ~700ms 2nd+ identical query same collection: just ~200ms ! ? My XML-files are OPTIMIZE'd on import, but the created indexes would influence the 1st query already. This is a great speed bump, but hard on tests that assume a first query on a recently imported new collection. So i wondered how this behavior could be explained & maybe turned off for testing purposes? Cheers, Philipp

basexserver start
by cmarchand＠oxiane.com 21 Aug '15

21 Aug '15

Hello, I want to monitor garbage collect on basex server. So, I've modified basexserver as this : BASEX_JVM="-Xmx6144m $BASEX_JVM -Xloggc:/home/basex/logs/79/azul/gc.log.$(date -u +%Y-%m-%d-%H-%M) \ -verbose:gc \ -XX:+PrintGCDateStamps \ -XX:+PrintGCDetails \ -XX:+PrintGCApplicationStoppedTime -javaagent:/usr/local/jHiccup/jHiccup.jar=-d,5000,-i,1000,-s,3,-l,/home/basex/logs/79/azul/hiccuplog,-c" # Run code java -cp "$CP" $BASEX_JVM "${vm_args[@]}" org.basex.BaseXServer "${general_args[@]}" The problem is I have only 2 seconds of monitoring. Does BaseXServer is a starter for another JVM ? How can I activate GC log on basex server ? Thanks in advance, Christophe

Performance and heavy load
by Martín Ferrari 19 Aug '15

19 Aug '15

Hi guys, I'm quite new to BaseX. I've read a bit already, but perhaps you can help so I can investigate further. We are having a performance problem with our BaseX server. We're running it on a VM, and hitting it from around 5 web servers. Under no stress, I get this timing from the log for a 1191 bytes file. 00:01:23.526 ww.aa.yy.xx:56312 admin REQUEST [PUT] http://basex.xxxxxx:8984/rest/PaymentLogs_1/WRP.BR-4273791-1_PaymentGateway… ww.aa.yy.xx:56312 admin 201 1 resource(s) replaced in 1401.17 ms. 1441.24 ms A call to /rest takes about 4-5 ms (it's called around once each 2 seconds, though it's not needed): 00:01:23.520 ww.aa.yy.zz:56312 admin REQUEST [GET] http://basex.xxxxxxxx:8984/rest00:01:23.524 ww.aa.yy.xx:56312 admin 200 4.67 ms Is the 1400 ms time normal for storing one xml file less than 2kb (storing a 10kb file took 1200 ms, so I'm not sure size mattered that much)? And also, when the load starts to get heavier, from 7 to 12 files per second, BaseX server quickly starts to get slower, then taking minutes to respond, until finally it starts giving errors about the database being currently opened by another process, and too many open files. Many connections remain in the CLOSE_WAIT state, and the server is no longer usable. Is it reasonable to expect to [PUT] more than 10 files per second, some of them taking more than 10kb? We're using it for logging, so that's a lot of xml files. If it's reasonable to use it that way, I'll dig more into optimizing it. Is anyone using it in a similar way? Thanks, Martín.

Do you know how non-ASCII characters, such as combining characters, are stored in that format? Maybe convert:string-to-hex and convert:binary-to-string [1] could be used to convert the result to the correct encoding. Basically, all we do in BaseX is using standard JDBC functionality [2]. If there is an easy way to fix the issue with JDBC, it should be easy to also get it working in XQuery.

Converting to UTF-8 in SQL module
by Tim Thompson 17 Aug '15

17 Aug '15

Hello, I am using the BaseX SQL module to query the Oracle database of a library catalog. Its character data is encoded as ISO 2709 (MARC-8)[1] and is stored in Oracle as US7ASCII. The data contains diacritics with combining characters like this: http://www.fileformat.info/info/unicode/char/0301/index.htm When I run the query in BaseX, all characters with combining accents are output as something like Ì Has anyone had experience handling this kind of encoding issue in BaseX, or does anyone have any solutions/approaches to recommend as a way to convert this data to UTF-8?
