I Christian, i tried and this is my error: Error:Could not create the Java Virtual Machine Error:A fatal Exception has occured.Program will exit   --------- Original Message -------- Da: "Christian GrÃ¼n" <christian.gruen(a)gmail.com> To: Cc: "Hondros Constantine ELS-AMS" <C.Hondros(a)elsevier.com>om>, "BaseX" <basex-talk(a)mailman.uni-konstanz.de> Oggetto: Re: [basex-talk] out of main memory Data: 03/03/16 11:57 > I tried to do what i suggested Costantine with the value 1024m, but my > memory is alwais 495m. Please try the following: 1. Download the ZIP version of BaseX (http://files.basex.org/releases/latest/) 2. Unzip it, edit bin/basexgui.bat (provided that you are using Windows): OLD: set BASEX_JVM=-Xmx512m %BASEX_JVM% NEW: set BASEX_JVM=-Xmx4g %BASEX_JVM% 3. Start bin/basexgui.bat 4. Click on the lower right memory bar and compare it with the attached screenshot. Does this help?

Import module with xquery:eval() function
by Ioan Fericel 03 Mar '16

03 Mar '16

Hi, I try to import a module dynamically, as in this example from a earlier discussion: > let $s:='import module namespace p="xquery-30" at "../repotest/test.xqm"; > p:parse-XQuery("2+2")' > return xquery:eval($s) It gives me the following error: > . . . [XQST0059] Could not retrieve module '/home/repotest/test.xqm'. I run BaseX 8.3 as war in Tomcat container. If the module is imported in static way: > import module namespace p = "xquery-30 " at "../repotest/test.xqm"; everything works correctly. From where does the problem with malformed relative path, what solution could be found? Thanks, Ioan

Parallel execution
by Klāvs Priedītis 02 Mar '16

02 Mar '16

Hello, BaseX team and community! Disclosure: I am not yet an expert on these issues and I have not fully studied the specs of XQuery. Now that Async Module is incorporated, I am wondering about some basic properties of xquery. Example: ```xquery for $i in 1 to 10 return fetch:text("http://example.com/magic-story/for-number/" || $i) ``` It feels to me that the xquery processor is broken if it cannot figure out on its own that the fetch can be done in parallel. Why does this not work out of the box? Can it work out of the box? Wouldn't it be able to do this in parallel if a flag `can-be-optimized-for-parallel-execution` was defined for the `fetch:text`? -- Veiksmi vēlot, Klāvs Priedītis

BaseX in a Multi-User VM
by Cecil Tarasoff 02 Mar '16

02 Mar '16

Hello, The environment that I am using BaseX GUI in is on a Virtual Workstation that is shared by multiple users. I am finding that my preferences end up being global and any user of BaseX on this workstation seems to be using the preferences that I have defined. Is it possible to install BaseX onto a multi-user workstation so that we each have our own config and repositories and keep our own data private? Thanks. Cec Tarasoff.

client:query freeze
by Strasser Pablo 01 Mar '16

01 Mar '16

Hi, Thanks for your great software. Using basex 8.4. I found the following strange behaviour in client:query call. Calling a repository function which use client:query to call another repository function freeze the basex server if done on the server. The only way to stop the server is with a kill -9. However using the standalone client it work normally. Trying to reproduce this problem I managed to get a similar problem using 2 repository test and test2. Where the first repo use a function of the second. Do you have some idea how to investigate this problem? Is it a bug? Code of test: module namespace m = 'http://strasser-family.ch/test'; declare variable $m:c := client:connect('localhost', 1984, 'admin', 'admin'); declare function m:test(){ client:query($m:c, "import module namespace m = 'http://strasser-family.ch/test2';m:test()") }; Code of test2: module namespace m = 'http://strasser-family.ch/test2'; declare function m:test() { <dummy/> }; usage code: import module namespace m = 'http://strasser-family.ch/test'; m:test() Have a nice evening.
