I’ve updated some of my ASH scripts to use these 4 arguments in a standard way: What ASH columns to display (and aggregate by) Which ASH rows to use for the report (filter) Time range start Time range end So this means whenever I run ashtop (or dashtop) for example, I need to type in all 4 parameters. The example below would show top SQL_IDs only for user SOE sessions from last hour of ASH samples: - Linux, Oracle, SQL performance tuning and troubleshooting - consulting & training.
