Secondly, Check and verify Oracle binaries are exist or not till now :

[oracle@test deinstall]$
[oracle@test deinstall]$ ls -ld /u01/app/oracle/product/19.0.0/dbhome_1
ls: cannot access /u01/app/oracle/product/19.0.0/dbhome_1: No such file or directory
[oracle@test deinstall]$

Lastly, you need to remove some files as root user :

[root@test ~]#
[root@test ~]# rm -rf /etc/oraInst.loc
[root@test ~]#
[root@test ~]# rm -rf /opt/ORCLfmap
[root@test ~]#
[root@test ~]#
[root@test ~]# rm -rf /etc/oratab
[root@test ~]#

About Oracle Deinstallation Options:

You’ll stop and take away Oracle Database software and components in an Oracle home with the deinstallation command.

The deinstall command is obtainable in Oracle home directories after installation. It’s located in the $ORACLE_HOME/deinstall directory.

This command creates a response file by using information in the Oracle home and using the data you provide.

Files Deleted by this command :

Thirdly, Before you run deinstaller command, please check and confirm if the central inventory (oraInventory) contains no other registered homes besides the home that you just are deconfiguring and removing. Most important things is, this command removes the following files and directory contents which all are in the Oracle base directory of the Oracle Database installation owner:

  • admin
  • cfgtoollogs
  • checkpoints
  • diag
  • oradata
  • fast_recovery_area
