Abstract
A query coordinator handles a multiple-server dynamic performance query by sending remote query slaves (1) first information for generating a complete plan for the query, and (2) second information for participating in the dynamic performance view portion of the query. If the slaves on the remote servers are unable to use the first information to generate an equivalent query (for example, if they reside in a database server that has closed the database), then the slaves on the remote servers use the second information to participate in the dynamic performance view portion of the query.
