Oracle dbca database encountered ORA-21561: oid generation failed error Solution

When I used dbca to create a database tonight, I entered the following interface and drove the machine to take a bath.

After the shower, I found that the progress bar was still 2%, and I felt something was wrong. So I went to the Installation Log displayed on the installation page and found the Database Report:

ORA-21561: oid generation failed

After repeated troubleshooting, I found that this virtual machine was copied. After I modified the/etc/sysconfig/network-scripts/ifcfg-eth0 and/etc/sysconfig/network file, I forgot to modify the/etc/hosts file.

In the/etc/hosts file, the Host IP and hostname ing are still from the source host. After you make a decisive correction, restart the server and re-install the host.
