BaseX for noobs: C++ API ?
by jean-marc Mercier 06 Jan '14

06 Jan '14

Hi all, going back to the root... I am trying to connect my favorite C++ tools to BaseX. Unfortunately, I am using visual C++ 12 Express under windows 7. It seems that windows users will not be able to use the existing BaseX API C connector, and need another one. Thus I started to code a C++ BaseX API connector. Writing a API connector is quite difficult for me, since I don't have the required networks knowledge. Has somebody already some code to that purposes ?

Hi,all, I have a restxq web service to do insert or update xml doc , which is called by many clients to provide xml data to db, there will be 500000 files to provide to basex server. I have found some problem few times : 1) often, after insert tens of thousands xml file, the db "list" will cause error,cause db corrupt, I don't know why, How, please help me. I don't know how to control the concurrently update db. 2) I often found there will automatically startup a basexhttp service in the server even the manually started service still run. ???, maybe the "basexhttp stop" command can't stop the service though it say stopped. the restxq service code as fellow: ---------------------------------------------------------- declare %output:method("xml") %output:omit-xml-declaration("no") %output:media-type("application/xml") %updating %rest:path("/add_ehr_doc") %rest:POST("{$body}") %rest:header-param("pid","{$pid}") %rest:header-param("doc_id","{$doc_id}") %rest:header-param("op","{$op}","APND") function ehr:add_ehr_doc( $body,$pid as xs:string,$doc_id as xs:string,$op as xs:string ) { let $dbname: ='myehr' let $fp:=substring($pid,1,6)||'/'||substring($pid,7,8)||'/'||substring($pid,15)||'.xml' (: pid is a patient id code as: area_code-section_code-serialnumber :) return try{ if (db:exists($dbname,$fp)) then ( insert node ($body//*:DataSet) into (doc($dbname||"/"||$fp)//*:BasicDataset), db:output(<msg><Ack>200:append</Ack><Url>{$fp}</Url></msg>) ) else ( db:add($dbname, $body,$fp),db:output(<msg><Ack>200 new add</Ack><Url>{$fp}</Url></msg>) ) } catch *{ db:output(<msg><Ack>201 error</Ack></msg>) } }; -- 此致林晓东莫愁前路无知己，天下谁人不识君。

Re: [basex-talk] Again need help on ft:search() :)
by Dirk Kirsten 31 Dec '13

31 Dec '13

Hello Anand, please make sure to send all help requests to the mailing list - this way all users can benefit from it. At the moment I don't see much potential to improve your query (but I am no expert on full-text search, so this is merely my opinion). The "all words" keywords are unnecessary, as you only use one word. The most important consideration is if the Full-Text Index is actually applied to your query. You can check by analyzing the query info, something like "Applying full-text index" should be found. You can find more information at https://docs.basex.org/wiki/Full-Text#Index_Processing So, have you created a Full-Text Index? This should definitely be your first step, as this will certainly boost your performance. You should also check the query info as suggested and also take a look at the optimized query plan given by the compiler, as this can point you to some bottlenecks in your query.

BaseX for noobs : how to add user module ?
by jean-marc Mercier 30 Dec '13

30 Dec '13

Hello, I am trying to add some external features to BaseX, and would like to use them into a BaseX client XQUERY module. I can't see any simple way to do it, is there any ? Here is the scenario : suppose that you want to add a super-mega map module to BaseX, let us call it supermegamap, that is a collection of functions : supermegamap:new, supermegamap:contains, supermegamap:get. I would like to use my supermegamap through BaseX via a xquery module : let $my_supermegamp := supermegamap:new(). I see only two quite not very handy ways to do this : 1) The first one is to use JAVA bindings. Ok, it will work, but is not really elegant. 2) The second one is to fork BaseX code : adding the JAVA code to BaseX, modifying the file Function.JAVA. That might work, should be efficient, but it is quite heavy, and overall, will be most probably a dead-code the next time I will have to upgrade BaseX. Is there any alternative way ? Thx Jean-Marc

Re: [basex-talk] BaseX-Talk Digest, Vol 48, Issue 60

Hi, The number (1, 2, 3,....) are the various searches done.. The huge amount (its not $$$$ ;) ) is the memory usage in K as indicated by Windows Task Manager. Query's, rather XQuery's are of various kinds, including XQuery functions like disitnct-values, casting functions, and many more.. some using joins, some using ft:search()... Well, I think, the reason would be in JAVA code itself, not related to BaseX..

Memory usage !!
by John Best 30 Dec '13

30 Dec '13

Dear Team, I have developed and application using Eclipse RCP. I am using BaseX 7.6 to store XML data. Yesterday, when I was testing the application with various kind of searches, the response was quite slow as I went ahead with more and more searches. To my surprise, I notices the in Windows Task Manager, the javaw.exe was consuming more memory... Then I restarted the laptop and did this procedure again Following is the memory usage - 1 - 84920 2 - 101584 3 - 108224 4 - 109284 5 - 111768 6 - 128468 7 - 160616 8 - 180212 9 - 198313 10 - 212592 Why this is so ? and how can I reduce this memory usage by javaw.exe ? -- Have a nice day JBest
