Apex: Upgrade from 5.1 on dbcs and oci-classic

After an Apex upgrade from 5.1.0.00.45 to 18.1 or after any dbcs patch upgrade, for example once the 18.2 patch has been applied:

# Setup again the ORDS certificate as discussed in this note.

# Reimplement the ORDS logging as discussed in this note.

# Optionally review the wallet and sqlnet.ora files

# Copy again the Apex 18.1 images

from /u01/app/oracle/product/apex/18.1/apex/images/

to /u01/app/oracle/product/ords/conf/ords/standalone/doc_root/i

All set.
