Support for RHEL Instances at No Additional Cost with Oracle Linux on Oracle Cloud Infrastructure

Julie Wong-OracleMay 7 2019 — edited Jul 22 2019

Oracle supports Red Hat Enterprise Linux (RHEL) installations by providing Oracle Linux Premier Support included as part of OCI subscriptions at no additional cost to OCI customers. To update RHEL instances, Oracle provides updates that are available as Oracle Linux binaries. Such binaries are fully compatible with RHEL and will work without any reinstallation or other coding changes.

Oracle provides updates for RHEL instances from the Oracle Linux yum server in Oracle Cloud Infrastructure and the Unbreakable Linux Network (ULN).  All security and bug fix errata will be Oracle Linux binaries.  Refer to the Getting Started – How to Connect to Oracle Linux Yum Server document on how to connect to the Oracle Linux yum server and obtain software updates via yum for Oracle Linux and compatible Linux distributions such as Red Hat Enterprise Linux (RHEL) and CentOS.  It is recommended that you use the local yum server in Oracle Cloud Infrastructure rather than the Unbreakable Linux Network (ULN) when running Oracle Linux in Oracle Cloud Infrastructure, since access to the OCI regional yum server is faster and does not incur any network charges.

You can also use Oracle Ksplice for zero-downtime patching of your RHEL instances on Oracle Cloud Infrastructure.  Oracle Ksplice is supported for RHEL, CentOS, and Ubuntu instances on Oracle Cloud Infrastructure (OCI) at no additional cost to OCI customers.  More information can be found in the in the Installing Ksplice Uptrack within Oracle Cloud Infrastructure section of the Ksplice User’s Guide.

You can choose to switch from Red Hat Enterprise Linux to Oracle Linux to take advantage of all the features and benefits provided, by applying Oracle Linux updates.  You can use the Oracle Linux Unbreakable Enterprise Kernel (UEK) or Red Hat Compatible Kernel (RHCK), which are both supported by Oracle. To change the default kernel (UEK) for Oracle Linux instances in Oracle Cloud Infrastructure, and boot into an older or other kernel such as RHCK, refer to the document: Oracle Linux – How to Change the Default Kernel.

I clicked on that link and the application downloaded and ran just fine. (At least it would have if I hadn't declined to allow it to run unrestricted on my system.) I didn't clear my cache or disable my firewall or any of that BS that help desks like to tell you, either. But I do have Java 7 installed on my system, not Java 6.

Perhaps you are connecting through some kind of proxy server which is rejecting some of the JNLP's requests and returning HTML saying so?

- In JNLP, do something mentioned below:
<j2se version="1.6.10+" href="http://java.sun.com/products/autodl/j2se"
java-vm-args="-Djava.net.preferIPv4Stack=true"/>

This may help you....

So, I had exactly the same issue as above for a long time now, the helpdesk tried their best and followed up but this piece of code did the trick.

I opened the JNLP file in wordpad and replaced everything that came after "<J2se version=" with what you gave above, so that it looked like this:

j2se version="1.6.10+" href="http://java.sun.com/products/autodl/j2se"
java-vm-args="-Djava.net.preferIPv4Stack=true"/

then I opened the file in the Java Web Launcher
and voila, the darn thing worked.

Hi, I've missed three weeks of classes because of the same error listed above.  Everything was fine and Blackboard Collaborate Elluminate worked almost effortlessly for 5 or 6 weeks.  Suddenly I tried to log in for a live lecture and this error occurred.  Other students were having trouble and still are.  Tech support at the school couldn't fix it, so they referred me to Blackboard Collaborate tech support (level 2).  They haven't been able to fix it either.  They recommended the same steps listed at the top of this email.  I executed all of them but still receive the same error.  Additionally, at one point, I was unable to install Java.  Funny things seem to happen when I get on the line with tech support to solve this problem, although funny things don't happen during the other work I do on this computer.  Technical language, I know.  :-)

In an effort to pass the class, I am doing research on own to try to fix this and get into the lectures.

I am getting the same error listed above but am not a developer and don't understand how to get to JNLP to enter the fix listed above (if someone has a hint, I'd love to try that fix).

Any help would be very much appreciated. 

System Info

OS:  Windows 8

Browsers:  IE (threw this one out), Chrome, Firefox, Safari (tested in all four)

Sample of Recorded lectures I'm trying to access (missed live ones):

Here are steps taken so far:

1. Clear Java Installed Apps and Applets (Control Panel - Java 32-bit - SEttings - Delete files - Installed apps and applets - ok - ok - ok)

2.  Delete all files in Downloads folder (from all browsers)

3.  Allow Java in Windows firewall (Start screen - hold down Windows key and W - Search for "firewall" - Navigate to Java program name - click all boxes and save)

4.  Ran CCleaner to remove all temporary internet files, cookies, etc. that could be interfering

5.  When nothing else worked, uninstalled and reinstalled Java twice (on the second time, it took over a dozen tries to reinstall Java - suddenly it just worked) and both times I deleted the Sun folder (C:/Users/Me/appdata/LocalLow/Sun) at the direction of tech support

6.  Removed old registry entries both times using CCleaner

7.  Rebooted (something done all along the way to see if it helped)

8.  Tried to access live classes and recordings from multiple lectures through Blackboard Collaborate Elluminate and received the same error (details included below)

9.  Tried to access Blackboard Collaborate Elluminate with Windows firewall on, then Windows firewall off, then ZoneAlarm Extreme firewall on, then ZoneAlarm Extreme firewall off (and entire associated software package); when on, ZoneAlarm gives "super" trusted status to all parts of Java listed and gives green checkmarks for all parts of Java listed and all levels of security

10.  End results so far:  receiving same error - nothing works

Here's the error followed by a copy of all text from the details section.
