How can I install Oracle REST Data Services? Well, it starts with downloading the media. And, if you’re a fan of the open source package management system for Linux known as ‘yum’, then installing ORDS just got that much easier.

Adding the Oracle Repo to your yum config

This is assuming you’re on Linux 7…there’s also one for version 8!

You need to use this command to tell yum to include the Oracle Repos for software packages:

[oracle@localhost ~]$ sudo  yum-config-manager --add-repo=
[sudo] password for oracle: 
Loaded plugins: langpacks
adding repo from:

name=added from:

Finding ORDS and Installing it

You can use the ‘yum info’ command to see if the archive is available, and what version it is, etc.

[oracle@localhost ~]$ yum info ords
Loaded plugins: langpacks, ulninfo

What just happened, and are we done yet?

Our ORDS helper program was downloaded and extracted to /usr/local/bin.

Yum didn’t know we had Java, so it pulled down the Open-JDK version 8 for ORDS as Java is listed as a dependency in the RPM.

So NOW we can actually do the configuration of ORDS and start it up.

This installer text should look extremely familiar if you’ve done an ORDS install/config before. But, let’s list a few import things to keep in mind:

  • if you enable SQL Developer Web – you get ALL the ORDS feature
  • HTTP is the default, but in real world you REALLY WANT HTTPS
  • if you select HTTPS, ORDS will generate a self-signed SSL Cert – don’s use this, get a real one from somewhere like Let’s Encrypt and use that
  • you’ll want to create an ords script to start it up as your machine comes up, it’s pretty simple, just do ‘ords’ or ‘ords standalone’ – if you want help, run ‘ords help’

I already have the ORDS_METADATA and ORDS_PUBLIC_USER setup in my database, so when ORDS sees those, it’s good to go.

If you’re doing a setup for the first time on a database, you’ll be prompted for an admin account (like SYS) to do the install, so be sure to have your DBA on hand, not to mention their blessing for deploying ORDS on their database.

ORDS is running, and I can login with SQL Developer Web to start building my REST APIs.

  1. Hi Jeff,

    Great News.

    1) Would you consider this for production as well? Or would running it in tomcat or weblogic be better suitable than the standalone version?

    2) wouldn’t it make sense to provide a systemctl service to automatically start the service? So that I don’t have to implement those scripts myself?


    • 1. yes standalone already supported for production, and many places at Oracle run it this way
      2. I’m reminded by smart people that doing yum install sets this up for you already

    • Hi Jeff,
      in the meantime I got the opportunity to try this in a production setting with Oracle Linux 8 on OCI. We ran into two issues so far:
      1) the systemctl scripts seem to be broken at least for Oracle Linux 8. In /etc/init.d/ords I had to do two modifications to get it to work:
      change ORDS_CONFIG=$( printf “%q” “$ORDS_CONFIG” ) to
      export ORDS_CONFIG=$( printf “%q” “$ORDS_CONFIG” )
      remove /comment out the line:
      export APP_VM_OPTS=$app_vm_opts to
      maybe the second one is “just for my setting”, but the first part I think is a generic bug. Is this something known? Or should I create an SR?

      2) I run the standalone ords on port 8080/http and put an OCI Load balancer in front of it that terminates the HTTPS. That does only work for APEX when I include
      See 2139195.1 where I got that from, however I kind of think this is still a bug since my LB is passing all the X-Forwarded/Host-Headers correctly. Is this a “known working setting”? I created SR 3-29614310421 for this in case you’d like to check further.

    Would it be possible to have this installed inside a tomcat instance as well Jeff ?

    Is there the option to do the configuration in silent mode? I.e. prepare a parameter file and use that during the configuration, without user interaction?
