I am trying to execute a job QualityStage - MATCH among two files with 700 thousand lines, but return error:

Error from Run: Error exec: E:/Projects/ERP/Logs/MADNECPV.MTC.StepMTCH_1.log:mtch(8084):6/21/2006 12:40:46 PM

When I reduce the size of the files, the job executes with success.

Please help me.

My first impression tells me that's around the blocking keys you have defined.

It look's like you have chosen a blocking key that will contains an enormous amount of records in one pass. So, during execution QS will be using thousands of records in the match phase.

I'm not sure if this will solve this problem, but, can you add another field in the blocking key to prevent this situation?

I will add new fields in blocking phase and to execute the job again.

I believe that is quite so. In the documentation of QualityStage (userGuide), it recommends that the blocks have approximately 10 to 20 records per file and that it should not exceed 100 records.

Thank you.
