You can run deinstall from the $ORACLE_HOME/deinstall directory. The deinstallation starts without prompting you for the Oracle home path.

$ ./deinstall

You can generate a deinstallation response file by running the deinstall command with the -checkonly flag.

./deinstall -silent --checkonly

The deinstall tool generates a response file in /tmp and displays the location. For example, /tmp/deinstall2024-08-01_01-40-28PM/response/deinstall_Ora26Client1.rsp

Use the optional flag -paramfile to run this response file:

$ cd /u01/app/oracle/product/23.0.0/client_1/deinstall
$ ./deinstall -paramfile /tmp/deinstall2024-08-01_01-40-28PM/response/deinstall_Ora26Client1.rsp
