Today, we will examine the AHF tool offered by Oracle, which offers us the tools we used as orachk and exachk with more advanced features.<\/p>\n

Oracle Autonnomous Health Framework (AHF) is an important tool that allows us to see errors and improve performance by making comprehensive checks on Oracle database exadata machine, cluster, grid and operating system, giving us advice.<\/p>\n

However, AHF can also be used for checks prior to upgrading a database.<\/p>\n

The report that comes out as a result of the operation of the tool offers us the parametric values that should be or what needs to be done.<\/p>\n

You can download the Oracle AHF tool from the address below with your Oracle Support account.<\/p>\n

Autonomous Health Framework (AHF) \u2013 Including TFA and ORAchk\/EXAChk<\/pre>\n
Running Oracle AHF with root privileges will enable you to benefit from all its features.<\/p>\n
If you run it with a different user, you will likely have to do the checks manually.<\/p>\n
However, some packages must be installed before starting the installation of Oracle AHF.<\/p>\n
Lack of packets will prevent the AHF tool from working properly.<\/p>\n
# yum install -y perl-Digest-MD5 perl-Data-Dumper<\/pre>\n
With our Oracle Support account, we can start the installation of our AHF tool that we downloaded and installed on our operating system.<\/p>\n
