We run both CA-Datacom and DB2; my perception (not yet backed up by figures) is 
that Datacom is considerably less resource-intensive than DB2.  One thing I 
hope to do this year is to figure out a way to compare their performance.  
First I need to make sure they are reasonably well-tuned, though, and then I 
need to try to determine what sort of differences there are in resource 
chargeback.

of CA-DATACOM to Oracle.

Given that CA-DATACOM is a '4gl' database, I would suspect that it might
not scale well and may have been slurping a lot of horsepower. And,
given CA's historic pricing postures.....
