The command completed successfully
I have highlighted the relevant section in bold, where you can see that the listener is indeed now
listening on port 8080 and understands to expect HTTP traffic on that port.
The next step is to install APEX if you have not done so already (we will assume you have!) and then
to configure the EPG by running the script apex epg config.sql , which is one of the scripts included in
the APEX download.
system@ae1> @apex epg config /tmp
Here we pass a parameter to the script, which is the directory that you unzipped the APEX download
into—in this case, the /tmp directory. The next step we need to perform is to unlock the ANONYMOUS
account, since that is the account the EPG will use:
system@ae1> alter user anonymous account unlock;
The final step, which is documented in the APEX installation guide, is to load the static APEX files
such as the JavaScript, CSS, and images into the EPG, by running the following script:
system@ae1> @apxldimg.sql /tmp
Again we pass the directory we unzipped APEX into as a parameter, so that the apxldimg.sql script
can locate the static files.
We should now be able to access our APEX instance using the port (8080) that we specified earlier,
as shown in Figure 1-20.
