What is Autonomous Health Framework (AHF)

Autonomous Health Framework (AHF) combines the existing Trace File Analyzer (TFA) and ORAchk/EXAchk , along with a bunch of other stuff , into a single download and setup. For any scenario where you would have installed one of these individual tools, you should now install AHF. It's a good idea to upload the AHF output as part of any support request, as they will just ask you to do it anyway. Is that it? Well, if you install AHF using the root user and start everything as daemon processes, it will give you proactive health monitoring, which could help you fix issues before they become a problem.

Before We Start

Just some things to consider before we start. - Make sure you have installed the "perl-Digest-MD5" package before you start. Without it you will receive a "Can't locate Digest/MD5.pm in @INC" error when you install, and subsequently run some commands. AHF thinks it's installed properly, but it hasn't. The command to do this install is listed below. Make sure you have installed the "perl-Digest-MD5" package before you start. Without it you will receive a "Can't locate Digest/MD5.pm in @INC" error when you install, and subsequently run some commands. AHF thinks it's installed properly, but it hasn't. The command to do this install is listed below. - You will get a lot more out of these tools if you install AHF as root. Without that you are going to have to manually run checks, or manually schedule them. - The current version (19.3) won't accept my email address as a valid email. It will accept a "-" before the "@" in an email address, but not after. I've raised a SR for this with Oracle Support (Bug : 30484078) and it will be fixed in a future release. For now the workaround is the use the following command once the installation is complete. The current version (19.3) won't accept my email address as a valid email.

Download Autonomous Health Framework (AHF)

Autonomous Health Framework (AHF) will be shipped with new releases of the database, but you should always download the latest version. The following location gives an overview of the AHF product, as well as download links and basic instructions. - Autonomous Health Framework (AHF) - Including TFA and ORAchk/EXAChk (Doc ID 2550798.1) This article assumes you've downloaded the latest version of AHF and it is placed in the "/u01/software" directory.

Install Oracle Autonomous Health Framework (AHF) (as root user)

Autonomous Health Framework (AHF) can be installed as the "root" user on the server, which provides the most functionality and allows it to run in a proactive manner as a daemon. In this example we will perform an installation as the root user. Unzip the software and run the command. Answer the questions when prompted. The following is an example of the root installation. As shown above, the and commands are available from the following directory. As part of the installation the service will be enabled and started.

Install Oracle Autonomous Health Framework (AHF) (as non-root user)

Autonomous Health Framework (AHF) can be installed as the "root" user on the server, which provides the most functionality and allows it to run in a proactive manner as a daemon, or locally as the Oracle software owner. In this example we will perform a local installation, making it a reactive tool. Unzip the software, create a destination location and install the software using the "-ahf_loc" flag. Answer the questions when prompted. The following is an example of the non-root installation. As shown above, the and commands are available from the following directory.

Code/Command (click line numbers to comment):

$ cd /u01/software

Run ORAchk

With the installation complete we can use the command to check the services running on the server. This can be done on-demand, or run as a background task, which will send an email to the notification email addresses. When is used MOS ID 2550798.1 states the following comliance check will happen. - Severe problems checked once a day at 2am. - All problems checked on Sunday at 3am. - Failures or differences since the last run are sent to the notification email address(es). The following is an example of the output from run from the root user. Once this is complete the service will be enabled and running.

Run a TFA Collection

With the installation complete we can use the command to perform a number of collections, including TFA Service Request Data Collections (SRDC). There are a large number of SRDC collection types, with each gathering different information, as described here . Here are a few examples. Each TFA collection produces a single zip file that can be uploaded to My Oracle Support (MOS), as described below.

Code/Command (click line numbers to comment):

# root
cd /opt/oracle.ahf/bin
# non-root
cd $ORACLE_HOME/ahf/oracle.ahf/bin


# Gather information about errors. You are prompted to select a specific incident.
./tfactl diagcollect -srdc ORA-00600
./tfactl diagcollect -srdc ORA-07445

# Collect data for all components for a specific time period.
./tfactl diagcollect -from "2018-06-16 13:00:00" -to "2018-06-16 13:00:00"

# Collect data for all components for the last 12 hours.
./tfactl diagcollect

Upload Files to My Oracle Support (MOS)

You can manually upload a zip file produced by TFA or ORAchk by attaching it to your SR through the MOS website in the normal way. An alternative is to get TFA to upload it and attach it to your Service Request (SR). To do this you must provide your MOS credentials. This can be done as part of the command line, or they can be stored in a secure wallet by running the following command as the "root" user. The result of a TFA collection can be uploaded directly to MOS by including the "-sr" option in the command to specify the target SR number. You can upload one or more files (both TFA generated and other files) as a separate action using the following commands.
