How to detach an ORACLE_HOME to an existing inventory

I want to detach an existing oracle_home from my inventory.

Note that the last argument must be the full path to the oracle software, NOT the oracle name found in the inventory:

./runInstaller -silent -detachHome ORACLE_HOME="/sw/oracle/product/19c29"
Starting Oracle Universal Installer...

Checking swap space: must be greater than 500 MB.   Actual 6143 MB    Passed
The inventory pointer is located at /etc/oraInst.loc
You can find the log of this install session at:
 /home/oracle/oraInventory/logs/DetachHome2026-01-25_12-51-17PM.log
'DetachHome' was successful.
