Hi Mark
I suspect you will find WebLogic is overkill for your needs, to be honest,
my personal preference for ORDS is to use tomcat as the app server, its
dead easy to get up and running (and the price is nicer too).
I'm not sure I entirely like LS' database/schema analogy, The relevant
documentation is at
https://docs.oracle.com/cd/E21764_01/web.1111/e14140/intro.htm#WLDCW101 ;,
but a WebLogic domain is a unit of administration for at least one, but
potentially many different *instances *of WebLogic running on one or more
physical servers. Each of those instances is a managed server running one
or more J2EE applications. In the case of ORDS, you'll either need a single
WebLogic server instance running both as an admin server and hosting the
ORDS application, or if you want resilience to server failure then maybe
you would create a WebLogic cluster in your domain. It's also worth reading
up on node manager (
https://docs.oracle.com/cd/E21764_01/web.1111/e13740/overview.htm#NODEM113)
if you have HA requirements and will be using multiple machines.
One thing I would say, whichever app server you choose, is that a single
ORDS instance is perfectly capable of serving multiple databases - see
https://docs.oracle.com/en/database/oracle/oracle-rest-data-services/19.1/aelig/configuring-REST-data-services.html#GUID-CC24128B-461A-4B8D-8722-7BD2D7E625BC
for
example and it may well be that the capacity requirements for your
applications don't require more than one or two application servers running
ORDS. Obviously, you might have firewalls or geographic considerations that
mean a single ORDS server (or a couple behind a load balancer) doesn't make
sense.

Hi LS,
Thanks again for the pointers. Do you know about Glasfish? Is a domain
in WLS similar to a domain in Glassfish?
Or is it more likely that a WLS managed server is like a domain?
Ultimately, I need to deploy multiple 'ords.war' files, for different
apps, configured to talk to different databases.
So, do I create one domain, say 'base_domain', and create multiple managed
servers under it, and deplpy an 'ords.war' into each managed server?
Or have multiple domains, and deploy one 'ords.war' file per domain?
Thanks!

Hi Mark
Quick explanation.
After installation you have to create domains, during domain creation
you can create managed server.
https://docs.oracle.com/en/middleware/lifecycle/12.2.1.3/wldcw/creating-weblogic-domain.html#GUID-0806FAE0-74B4-4D28-A407-9C560CC8C009
https://docs.oracle.com/en/middleware/lifecycle/12.2.1.3/asadm/scaling-your-environment.html#GUID-A8CF8AFE-7044-4162-83FD-DED75D3A05E7
The domain is like database and managed server like a schema, in
database terms. A default domain without any managed server creates by
default the administration server, if you create new managed server are new
weblogic instances.
After domain and managed server creation you get these scripts
$DOMAIN_HOME/bin/startWebLogic.sh ===> this starts the administration
server
$DOMAIN_HOME/bin/startManagedWebLogic.sh ===> this starts the managed
server
I learnt all when working with Forms & Reports :-)

Hi all,
I've been working with APEX/ORDS/Glassfish for years, but recently, I
tried the latest version of Glassfish, 5.1.0, no longer under control of
Oracle, and was having a deployment error with ords.war. (Something about
CDI...?)
Anyhow, I know latest version of ORDS still supports Glassfish, but
it's deprecated, and the days are numbered.
So, I thought, no time like the present, let's try Oracle WebLogic
Server.
So, first, while I'm quite comfortable with Oracle Database, I have
*zero* experience with Oracle WebLogic Server. So, I was poking round the
web, and I found this, which I downloaded:
https://www.oracle.com/technetwork/middleware/weblogic/downloads/wls-main-097127.html
I managed to get it installed (I think), but I can't figure out what to
do, how to start it and start working with it. As I said, I have *no*
experience with WebLogic Server. FYI, when I indtsalled it, there weere
three options, "WebLogic",'Coherence", and "Complete with Examples", or
something like that. I installed the first option, "WebLogic".
I found a document, which said to do 'startWebLogic.sh' to start it,
but I have no such file in my newly installed Oracle home.
Can someone give me a clue, or possibly a link to some documentation
that will hold my hand and outline *exactly* what to do in which order?
Thanks!

PS I find this all very confusing, particularly the part about
WebLogic being part of Fusion Middelware? Anyhow, when you respond, please
do so as if I were a clueless idiot, because when it comes to WebLogic
Server, I pretty much am!
PPS Yes, I'm finally back at work. I did work from home last week,
and this Monday, and I've been in the office since Tuesday. I'm still not
100%, but I'm definitely feeling better.
