Data Base
• We were not able to simulate data handling with fictitious names though we believe our .xml format is correct. The problem may disappear as we proceed with real actions.
• Error: – “DB: ERROR: fatal error: 0RA-02291: integrity constraint (CMSTRKDB.REF_INPUT14)
violated – parent key not found– ORA-06512: at “CMSTRKDB.STORED_FUNCTIONS”, line 788– ORA-06512: at line 1
– …error goes on to list the text in the file. It is not just IV_TEST in particular. If this test is deleted and it goes straight to CV, the problem basically is repeated.

Conclusions and Plans•QTC at University of Rochester complies with CMS requirements to test Si detectors.
•Rate of the testing is estimated to be 2 OB2 sensors per day.
• Data Base remains an issue. The problem may disappear if everything is done in proper order using appropriate bar codes and all.
