Apex 18.2 and Ords 18.3 are now available.
To upgrade these versions in place, for example on an OCI DBsystem, from respectively Apex 18.1 and Ords 18.2:
#1 Download and unzip apex 18.3 in the n/u01/app/oracle/product/apex/18.3
#2 Upgrade apex
cd /u01/app/oracle/product/apex/18.3 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/latest rm images ln -s ../18.3/images images
#4 Download and unzip the ORDS zip file in the newly created directory
/u01/app/oracle/product/ords/18.3
#5 Upgrade the params files
cd /u01/app/oracle/product/ords/18.3/params cp /u01/app/oracle/product/ords/18.2/params/* .
#6 Upgrade the config directory
cd /u01/app/oracle/product/ords/18.3 java -jar ords.war configdir /u01/app/oracle/product/ords/config
#7 Upgrade the ORDS schema
cd /u01/app/oracle/product/ords/18.3 java -jar ords.war
The end of the process should start the ords server
