Hi All,

We use Oracle g10 as our DB and recently we decided to configure the data warehouse.
All the data collection jobs run .o.k., only the "Star" job fails.
I saw in the log "jts-etl" an error message:
Java ETL (STAR): Dimension build
"com.ibm.team.datawarehouse.service.starjobs.internal.dimensionbuild.ResourceDimension" failed

Any ideas what can cause the "Star" job to fail ?

THX,
Ziv

Yes, I'm afraid that I will have to ask for the drop and create the DW again...That's not easy, I'm not in a VMWare in testing, but in production in a critical client, with very strict and cumbersome processes...

Hello Ismael,

RIDW.D_DATE is indeed expected to be populated at the time the data warehouse is first created, so I suspect there was a problem at that stage.

If it's a new Data Warehouse and (meaning you have no concerns on losing trending data) I would try dropping and recreating it (paying particular attention to the logs for this operation).

Best Regards,

Francesco Chiossi

Hello Francesco,

Sorry for the misunderstanding. Yes, I meant the tables from RIDW...
For example, RIDW.D_DATE is empty, RIDW.D_PROJECT is empty, and they should be filled through the createWarehouse command...

Hello Ismael,

RIDW.PROJECT_FK1 is not expected to be a table, but a constraint.

i.e. in DB2: select * from SYSCAT.TABCONST where CONSTNAME = 'PROJECT_FK1' and tabschema ='RIDW'

CONSTNAME TABSCHEMA TABNAME OWNER OWNERTYPE TYPE ENFORCED CHECKEXISTINGDATA ENABLEQUERYOPT DEFINER REMARKS
PROJECT_FK1 RIDW D_PROJECT DB2ADMIN U F Y I Y DB2ADMIN

so the table affected by the constraint is RIDW.D_PROJECT

Best Regards,

Francesco Chiossi

Francesco, thanks very much for your answer.

Exactly, these tables does not exist. My concern is WHY this tables does not exist!!?? The repotools -createWarehouse worked fine with no errors. Thus, I'm afraid to recreate the DW again and stumble on the same problem...

So yes, I will open a PMR to fix this issue...

Hello Ismael,

an error like " integrity constraint (RIDW.PROJECT_FK1) violated - parent key not found " sounds like there is a key that references another table, but in this table that value doesn't exist.
This usually hints to data corruption in the data warehouse.

I would suggest opening a PMR to get this investigated in depth as it might be necessary to share some queries and data from your data warehouse.

Best Regards,

Francesco Chiossi

 Hi,

Did you finally fix this issue about STAR ETL Job? Last year I reported same error in the Work Item Defect 267123, with no answer.
Basically, the jts-etl.log shows the following error: 

2014-02-27 09:25:50,909 [             WebContainer : 12]  INFO ervice.starjobs.internal.StarRemoteSnapshotService  - Java ETL : Started executing query: "com.ibm.team.datawarehouse.service.starjobs.internal.dimensionbuild.ProgramProjectDimension=>SELECT PJ.PROGRAM_ID AS PROGRAM_ID, PJ.PROJECT_ID, PJ.NAME, PC.NAME AS TYPE_NAME, PJ.ISSOFTDELETED FROM RIODS.PROJECT PJ JOIN RIODS.PROJECT_CLASSIFICATION PC ON PC.PROJECT_CLASS_ID=PJ.PROJECT_CLASS_ID WHERE PJ.PROJECT_ID>-1"
2014-02-27 09:25:50,985 [             WebContainer : 12] ERROR ervice.starjobs.internal.StarRemoteSnapshotService  - ORA-02291: integrity constraint (RIDW.PROJECT_FK1) violated - parent key not found

Thanks in advance!
