Custom Report - Top SQL for Locking Issues

DESCRIPTION

This procedure will return the top 30 SQL statements for the given instance and date range ordered by total seconds spent waiting on blocks. This report reads summary data, so running it for a time range less than one hour will not yield correct results.

Note: See comments inside the procedure for more details on the parameters and methods for calling. Install the stored procedure into the Ignite repository database.
