The apexins.sql script creates a log file in the apex directory using the naming convention installYYYY-MM-DD_HH24-MI-SS.log.
In a successful installation, the log file contains the following text:
Thank you for installing Oracle Application Express. Oracle Application Express is installed in the APEX_180200 schema.
If the log file contains a few errors, it does not mean that your installation failed. Note that acceptable errors are noted as such in the log file.
