Change AHF home from /opt/oracle.ahf to /u01/oracle.ahf

Problem:

One of our customers had 2GB space for /opt mount point. After running root.sh script during GI configuration, 926M sized /opt/oracle.ahf folder was created which caused problems later with the available space in /opt.

Please note root.sh runs TFA installation using the following way:

2020-07-07 09:41:10: CLSRSC-594: Executing installation step 1 of 19: 'SetupTFA'.
2020-07-07 09:41:10: Executed stage SetupTFA in 0 seconds
2020-07-07 09:41:10: Executing cmd: /u01/app/19.3.0/grid/crs/install/tfa_setup -silent -crshome /u01/app/19.3.0/grid

tfa_setup has an option -ahf_loc which is the Autonomous Health Framework home and the default value for it is /opt/oracle.ahf

There is a question, how can we avoid exhausting /opt space used by AHF?

Solution:

Choose only one: 1,2 or 3.

1. Increase /opt mount point size
2. Or, uninstall TFA (which deletes /opt/oracle.ahf folder and releases space) and reinstall it by indicating -ahf_loc option

# tfactl uninstall
# mkdir /u01/oracle.ahf
# chmod 755 /u01/oracle.ahf
# /u01/app/19.3.0/grid/crs/install/tfa_setup -ahf_loc /u01/oracle.ahf
...
AHF Location : /u01/oracle.ahf
Choose Data Directory from below options :
1. /u01/oracle.ahf [Free Space : 41347 MB]
2. /u01/app [Free Space : 41347 MB]
3. Enter a different Location

Choose Option [1 - 3] : 1
AHF Data Directory : /u01/oracle.ahf/data

3. Or, change default location for AHF home (AHF_HOME) before running root.sh script:

# mkdir /u01/oracle.ahf
# chmod 755 /u01/oracle.ahf
# export AHF_HOME=/u01/oracle.ahf
# /u01/app/19.3.0/grid/root.sh

Check that AHF home was created under /u01/oracle.ahf instead of /opt/oracle.ahf

# ll /opt|grep oracle.ahf

# ll /u01|grep oracle.ahf
drwxr-xr-x 10 root root 134 Jul 7 12:46 oracle.ahf
