While running the database creation process (DBCA), the completion percentage stops at 60% and does not continue.
Oracle 12c or higher versions
If the Oracle implementation guide has been followed correctly, the solution to this issue is environmental.
Oracle log evidence will show errors related to an account needed for database access during the creation process. This is caused by the environment blocking the account process.
As a suggestion, run Sysinternals Process Monitor to look for clues as to what may be blocking the installer from writing to disk.
For example, in one instance, a security software was limiting access to the temporary directory used for Oracle patching. Once the installer was whitelisted from the security software, the install completed successfully.
