Apex and Ords 19.1 are both available.
To upgrade these versions in place, for example on an OCI DBsystem, from respectively Apex 18.2 and Ords 18.3:
#1 Download and unzip apex 19.1 in the n/u01/app/oracle/product/apex/18.3
#2 Upgrade apex
cd /u01/app/oracle/product/apex/19.1 sqlplus / as sysdba <<EOF ALTER SESSION SET CONTAINER=<mycontainer> @apexins SYSAUX SYSAUX TEMP /i/ EOF
#3 Change the images symbolic links (quite convenient to handle periodic upgrades)
cd /u01/app/oracle/product/apex rm latest ln -s 19.1 latest
#4 Download and unzip the ORDS zip file in the newly created directory
/u01/app/oracle/product/ords/19.1
#5 Upgrade the params files
cd /u01/app/oracle/product/ords/18.3/params cp /u01/app/oracle/product/ords/19.1/params/* .
#6 Upgrade the config directory
cd /u01/app/oracle/product/ords/19.1 java -jar ords.war configdir /u01/app/oracle/product/ords/config
#7 Stop the current ords listener.
#8 Upgrade the ORDS schema
cd /u01/app/oracle/product/ords/19.1 java -jar ords.war
Specify the system username and password to connect to the ORDS schema in the PDB if applicable.
The end of the above process should start the ords server
