Questions and Answers

What happens when the CLEANUP script is configured to run on all entities in the DB?

  • It slows down considerably
  • It replaces truncate statements with delete statements
  • It adds more entities into the DB
  • It truncates the Warehouse tables and finishes quickly (correct)

Why does adding entities into the DB cause the CLEANUP script to run drastically slower?

  • Because it causes the script to replace truncate statements with delete statements
  • Due to insufficient memory allocated to the Murex Warehouse
  • It has no impact on the speed of the cleanup script
  • Because it introduces new entities that need to be cleaned up (correct)

What could be a potential cause if the cleanup process is hanging or taking a long time to complete?

  • Not enough processing units
  • The addition of new entities into the DB
  • Locks on the PS_%_EGC tables
  • Insufficient resources like memory or CPU time (correct)
