question about security

Hello Roland,

Congratulations on the project, very interesting. I was thinking of using it to test the security issues on the cubes https://mondrian.pentaho.com/documentation/schema.php#Access_control how could I proceed to pass the roles that the cube expects in xmondrian?

Problem with MariaDB 10.2

Hi,
I installed xmondrian under tomcat8 and tested it on our data with MySQL 5.7.22 - all works correctly.
Now I'm trying to switch it to the new database where the data will be migrated soon, and it does not work anymore. It seems that something is going wrong in getLevelMemberCount function, in mondrian.sql log I get the following logs:

2018-06-08 19:37:47,988 DEBUG [mondrian.sql] 3: SqlMemberSource.getLevelMemberCount: executing sql [
select
    count(*) as `c0`
from
    (select distinct
    `llx_olap_view_propal`.`date_valid_day` as `c0`,
    `llx_olap_view_propal`.`date_valid_month` as `c1`,
    `llx_olap_view_propal`.`date_valid_quarter` as `c2`,
    `llx_olap_view_propal`.`date_valid_year` as `c3`
from
    `llx_olap_view_propal` as `llx_olap_view_propal`) as `init`]

...for MySQL (working one)
and

2018-06-08 19:39:37,126 DEBUG [mondrian.sql] 3: SqlMemberSource.getLevelMemberCount: executing sql [

    count(DISTINCT `llx_olap_view_propal`.`date_valid_day``llx_olap_view_propal`.`date_valid_month``llx_olap_view_propal`.`date_valid_quarter``llx_olap_view_propal`.`date_valid_year`) as `c0`
from
    `llx_olap_view_propal` as `llx_olap_view_propal`]
2018-06-08 19:39:37,129 DEBUG [mondrian.sql] 3: , exec+fetch 3 ms, 0 rows
2018-06-08 19:39:37,129 DEBUG [mondrian.sql] 3: , failed (java.sql.SQLSyntaxErrorException: (conn=6863) You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '.`date_valid_quarter``llx_olap_view_propal`.`date_valid_year`) as `c0`)

...for MariaDB - error.
So in two cases, the SQL query is not the same, evidently the second query is incorrect.
I would try to fix it myself, but I cannot build mondrian, downloaded from https://github.com/pentaho/mondrian.
Can you share the build instructions, please?

Version of xmondrian for Mondrian 4

Maybe this has been discussed already and I've missed it/forgotten it, but would it be possible to create a variant of xmondrian that embeds Mondrian 4?

My colleagues report that xmondrian is very convenient to use, but we want to use Mondrian 4 (and develop new versions of Mondrian 4) and dropping Mondrian-4 into xmondrian.war produces some exceptions due to missing classes.

In http://rpbouman.blogspot.nl/2016/03/need-mondrian-war-checkout-xmondrian.html you say the ant script is "not particularly valuable to me but it's also not of very high quality that's why I'd rather not share it." Could you reconsider? It doesn't matter if it's crappy. We've all written crappy code that does the job. If it's open source we can make it better.

How do i connect with MySQL database?

Problem with Power BI

Hello,
I want to thank you for this project, very helpful but i have encountered an issue while connecting xmondrian xmla cube to Power BI as data source for Analysis Services using "http://localhost:8080/xmondrian/xmla" as Server name.

Error description:
We encountered an error while trying to connect.
Details: "AnalysisServices: XMLA SOAP Body processing error"

Please, any help !

cannot type in shell

Dear Roland, I just installed on my ubuntu machine
The problem is, I cannot type any query in shell
The cursor blink, but any button in my keyboard doesn't work
I attached the screenshot.
(Ubuntu 14.04/jdk7/tomcat8/FireFox & Chrome)

The source code is required for debugging.

Hi Roland,
I took your solution, but got an error at run time, which I can not understand. Could you post the full source code of the solution, not only WAR-file?

How to update schema and flush data cache without restarting xmondrian server?

Hi Roland,

Thanks for xmondrian, which make me easy to use mondrian to build OLAP engine.

I have one question about xmondrian cache. Once I modify the schema, or update the data in dw, I have to restart xmondrian server. Otherwise, I will get the old one. Would you have any suggestion to flush xmondrian cache? Should I write some codes to flush cache during xmondrian server is running? How to do it?

Thanks in advance.

How to update Xavier?

Hello Roland!
First, I would like to thank you because you are helping me immensely on my graduation.
I tried to to update the Xavier inside xmondrian with the new xavier.zip from it's repository, but now it doesn't recognize the datasource I specified in my datasource.xml file, a window opens instead and asks for the url of the xmla server. Is there a new configuration I'm missing?

Since i'm already here, I just discovered your Pentaho Analysis Editor and it looks a lot nicer than the Schema Workbench that i'm currently using. Is it mandatory that I use it with Pentaho or can I use it with xmondrian?

Thank you again.

SOAP-ENV:Server.00HSBE02

Hi.

I can't connect to DB2 data source.
I copied db2jcc.jar to WEB-INF/lib and set datasource information in datasources.xml:
Provider=mondrian;Jdbc=java:db2://192.168.30.20:50160/obmen:user=obmen;password=obmen;JdbcDrivers=com.ibm.db2.jcc.DB2Driver
What I did wrong?

xmondrian postgresql data source

Hi Roland,
Great work. Thanks. I am struggling with Mondrian releases and out of date documentation.
The xmondrain war file makes things so much easier.
Would you please help me connect xmondrian to PostgreSQL? I have Mondrian 3.5 samples in 3.5 (except for the XMLA ones) using Foodmart in PostgreSQL 9.5. I've confirmed by turning PostgreSQL logging on.
This DataSourceInfo works in 3,5 in datasources.xml
Provider=mondrian; Jdbc=jdbc:postgresql://localhost/Mondrian_Foodmart; JdbcDrivers=org.postgresql.Driver;JdbcUser=postgres;JdbcPassword=xxxx; Catalog=/WEB-INF/FoodMart.xml.
When I add the postgresql jdbc jar file and change the datasource.xml in xmondrian and use Xavier or Xmlash it fails with:
error SOAP-ENV:Server.00HSBE02: XMLA Discover unparse results error (source: _requestSuccess, actor: Mondrian) 00HSBE02: The Mondrian XML: Mondrian Error:Internal error: No suitable connection found. I am testing with tomcat and windows 7.
Thanks in advance for any tips.
Cheers,
Bob Doss
