Oracle Database 19.2 for Oracle Exadata systems is available for download since yesterday night. One important thing you need to take into account once Oracle 19c will be generally available: On Linux, Oracle Database 19c requires OL7, RHEL7 or SLES12 or newer.
Database Installation Guide for Linux
You will find the exact minimum OS and kernel version requirements in the Database Installation Guide for Linux for Oracle 19c. Please see here the Operating System Checklist for Oracle Database Installation on Linux:
- Oracle Linux 7.4 with the Unbreakable Enterprise Kernel 4: 4.1.12-112.16.7.el7uek.x86_64 or later
- Oracle Linux 7.4 with the Unbreakable Enterprise Kernel 5: 4.14.35-1818.1.6.el7uek.x86_64 or later
- Oracle Linux 7.4 with the Red Hat Compatible kernel: 3.10.0-622.214.171.124.1.el7.x86_64 or later
- Red Hat Enterprise Linux 7.4: 3.10.0-6126.96.36.199.1.el7.x86_64 or later
- SUSE Linux Enterprise Server 12 SP3: 4.4.103-92.56-default or later
You may recognize that there is no support of Oracle 19c on OL6 or RHEL6.
Both, OL6 and RHEL6 got released a long time ago. RHEL6 is available since November 2010, OL6 since February 2011 if I remember correctly. And even though the Red Hat 6 Maintenance-2 Support time frame runs until November 2020, this would require a later OS upgrade on your database server. Oracle Linux is supported longer and will be under Premier Support coverage until March 2021.
Just that you’ll be aware – make sure your Linux server runs at least one of the above OS kernel versions. And then you are ready to download and install Oracle Database 19c on-premises as soon as it becomes available.
