Hi, where are the log files stored? I recently copied the basex/data directory to another computer via scp and I saw that files like "2012-05-04.log" have been copied, too. But I do not find them in the original directory and also not in the target directory. Best regards Cerstin -- Dr. phil.

full text search collation
by alxarch 26 Jun '12

26 Jun '12

Hi I have a question relating to full text search. I am trying to use it with Greek texts and the default collation assumes that ά != α In short, accented vowels are treated as different letters. Is this something that has to do with the collation used not being Greek, or does it have something to do with the tokenizer? As a side question i noticed that the stemmers used from lucne are quite outdated. 3.6.0 also includes a Greek stemmer. I tried to include the 3.6.0 stemmers instead but language codes seem to be hardcoded in util/ft/Language.java Any chnce of that part of the code being updated to use the latest stemmers so more languages can be integrated? (i am not proficient in java myself unfortunately so i can't directly help) thanks, Alex

Validation Module

Hi all, I am trying to validate an incoming xml post message against an xsd stored inside the basex. But I am getting this error [FODC0002] Resource 'sampledb/xsd/match.xsd' does not exist. I am sure the path is correct and the xsd file exists there. May I know where I am going wrong? try { let $doc := |<simple:||root| |xmlns:simple=||'http://basex.org/simple'||/>| return validate:xsd($doc,'sampledb/xsd/match.xsd') } catch BXVA0001 { 'Validation failed.' } Thanks in advance.

Hi All, I builded a kind of connection pool using BaseXClient.java class, I simulated several users trying insert documents in BaseX, the result was a disaster. ERROR: data.BaseXDataAccess - Error closing db java.io.IOException: Stopped at line 1, column 19: Unknown command: 1340477810253095000. Try HELP. at data.BaseXClient.execute(BaseXClient.java:99) at data.BaseXClient.execute(BaseXClient.java:110) at data.BaseXDataAccess.save(BaseXDataAccess.java:169) at data.TestInsert$Insert.run(TestInsert.java:88) at java.lang.Thread.run(Thread.java:680) Exception in thread "Thread-1" java.lang.RuntimeException: java.io.IOException: at data.BaseXDataAccess.save(BaseXDataAccess.java:164) at data.TestInsert$Insert.run(TestInsert.java:88)ERROR: com.xftec.hyperion.data.BaseXDataAccess - Error closing db I started several threads each one takes a BaseXClient connection and as soon as it finishs its job BaseXClient is put in a queue again to be took by other thread.

deadlock in BaseXServer 6.2.7
by Godmar Back 23 Jun '12

23 Jun '12

Hi, we're observing that our BaseXServer 6.2.7 deadlocks. The stack traces are here: http://top.cs.vt.edu/~gback/bx/deadlock-6.2.7/basex-deadlock.txt Could you take a look to see if these ring any bells? Has this problem been addressed in a more recent version? - Godmar

safe to upgrade from 6.6.3 SNAPSHOT to 7.3?
by Godmar Back 23 Jun '12

23 Jun '12

Also - is it safe to upgrade to 7.3? We now have production data (or at least the beginnings thereof) in our BaseXData directory. Is the binary format still the same, or do we need to export/reimport the XML? - Godmar

Install issues
by André Milton 20 Jun '12

Hi guys, I'm having a hell of a time trying to install BaseX on CentOS with Yum. It says I'm missing xml-commons-resolver 1.2 and lucene-contrib: Resolving Dependencies --> Running transaction check ---> Package basex.noarch 0:7.2.1-3.2 set to be updated --> Processing Dependency: xml-commons-resolver = 1.2 for package: basex --> Processing Dependency: lucene-contrib for package: basex --> Processing Dependency: jline for package: basex --> Running transaction check ---> Package basex.noarch 0:7.2.1-3.2 set to be updated --> Processing Dependency: xml-commons-resolver = 1.2 for package: basex --> Processing Dependency: lucene-contrib for package: basex ---> Package jline.noarch 0:0.9.94-0.9.el5_6 set to be updated --> Finished Dependency Resolution basex-7.2.1-3.2.noarch from home_basex_opensuse has depsolving problems --> Missing Dependency: xml-commons-resolver = 1.2 is needed by package basex-7.2.1-3.2.noarch (home_basex_opensuse) basex-7.2.1-3.2.noarch from home_basex_opensuse has depsolving problems --> Missing Dependency: lucene-contrib is needed by package basex-7.2.1-3.2.noarch (home_basex_opensuse) Error: Missing Dependency: xml-commons-resolver = 1.2 is needed by package basex-7.2.1-3.2.noarch (home_basex_opensuse) Error: Missing Dependency: lucene-contrib is needed by package basex-7.2.1-3.2.noarch (home_basex_opensuse) I've downloaded both and added them to a CLASSPATH but the install script still complains. What step have I missed? Do I also need to add them to my PATH (would prefer not to)? Thanks! a+,a.
