Data source cannot be created : [MapperConfig] cannot add map data source.

511874

I'm getting this error:
*Data source cannot be created : [MapperConfig] cannot add map data source.*

while following the step 2 of MapViewer Demo Setup tutorial.

I've the BI server installed on a machine and set up the schema for demo data on a RAC database.

I was able to set up the scheduler connecting via OCI and TNS,
but now when I try to add, from OracleAS MapViewer Admin, the data source MVDEMO I get that error.

I'm using:
NAME mvdemo
BASED ON: TNS is selected
TNS Name: ORCL_TAF
User: mvdemo
Password: mvdemo
# Mappers: 3
Max Connections: 100

Thanks,
Marco

Hi Marco,

I had the same problem with the data sources and a RAC.

Did you edit your MapViewerConfig.xml?
You can find this XML in: j2ee/mapviewer/applications/mapviewer/web/WEB-INF/conf

I think you have to do this first and then restart your OC4J-Instance "mapviewer" with the option "-userThreads". You can do this on the EnterpriseManager in the "adminstration/server properties" or directly from the opmn.

Try this. I hope, this helps.

Hi Andrea,
I've read the metalink doc 402379.1 "How To Create RAC Datasource For Mapviewer" but actually I'm not getting explicity those errors.

I didn't try yet because our BI group is finishing a demo in these days.

I-ve solved reading Note:402379.1 How To Create RAC Datasource For Mapviewer and following your suggestions.
