Oratop is a text based user interface tool for monitoring basic database operations in real time. In this article we will explain how to use oratop tool .

There are two ways we can install oratop.

MTEHOD 1:( using TFACTL):

Now oracle is providing oratop, tfactl, oswatcher, orachk etc as part of Automatic health framework(AHF). So if AHF is installed , means oratop is already available.

STEPS FOR - > HOW TO INSTALL AHF :

Check whether the status using below tfactl command:

root@dbhost-1:/export/home/scsun# tfactl toolstatus
