Oracle Database 19c (19.3.0) Upgrade and Migration hands-on Lab

Hello Everyone,

I am new to this group. I need your help in resolving an issue I am facing. I downloaded the Oracle Database 19c (19.3.0) Upgrade and Migration hands-on Lab provided by Oracle. I unzipped all the files downloaded and it crated a single .ova file. I am running Oracle Enterprise Linux 7.6 on which I have a VirtualBox 5.3.30 running. I imported the .ova file and made sure the RAM is at 8 GB and the CPUs are at 4, before starting the VM. The VM boots up but I get a Black screen, and there is no login screen. Has anybody come across similar issue? If yes, what is the resolution to get the VM Login screen and proceed with the Lab. Your help in this regard would be very helpful.

Hi, out of curiosity I have made a few searches and here (https://mikedietrichde.com/hol-19c-setup-setup-for-the-oracle-19c-upgrade-hands-on-lab/)I have found this:

VERY IMPORTANT:

If the login screen does not appear but instead you get a BLACK screen after the reboot process, then please check this link here:

In the cases we encountered during the first run of the labs, two people struggled with it. The:
WaylandEnable=false
parameter brought the solution. I set this for the downloadable image already but people who get the lab via a USB drive in the early stages may miss this setting.

---8<---8<--8<---

I hope this helps.

@Srinivasa Ramanujam Paravastu Try to download the MD5 Checksum and verify the files you downloaded again i found that helped me find any corruption and resolve it before i start unpacking files.
