Tracking DB session information of ASM clients staying in certain state (Doc ID 2626288.1)

Last updated on MARCH 31, 2020

Applies to:

Oracle Database - Enterprise Edition - Version 11.2.0.2 and later
Information in this document applies to any platform.

Goal

Some times we need to track ASM clients that have executed a specific query or have staid with specific wait event.
In this document I describe to do that based on my experience that I tried to find out which ASM clients had large number of waits for 'ASM sync cache disk read' remaining in DB instances.

Wait event 'ASM sync cache disk read' means 'I/O wait event for reading a block from disk into the cache'
and its parameters mean.

P1 - group
P2 - obj#
P3 - block#
