About Oracle Big Data SQL 3.2.1.2

Release 3.2.1.2 supports Oracle Database 12.2.0.1 with the October 2018 DBRU (Database Release Update), as well as Oracle Database 12.1.

About Oracle Big Data Discovery 1.6

Big Data Discovery 1.6 supports Oracle Big Data Appliance 4.14. You can download the installation files from the Oracle Software Delivery Cloud (also known as eDelivery).

The procedures for installing and upgrading Big Data Discovery on Oracle Big Data Appliance have not changed with release 1.6. See Installing Oracle Big Data Discovery in the Oracle Big Data Appliance Owner's Guide for installation instructions. (This procedure differs from the one described in the Oracle Big Data Discovery Installation Guide.)

For upgrades, follow the instructions in the Oracle Big Data Discovery Upgrade Guide.

About Perfect Balance

Perfect Balance was removed from Oracle Big Data Appliance as of Release 4.13.

In-Place Procedure for Migrating Big Data Appliance Oracle Linux 6 Clusters to Oracle Linux 7

See Migrating from Oracle Linux 6 to Oracle Linux 7 in the Oracle Big Data Appliance Owner's Guide.

Uniform Service Layout for Multirack Clusters

In earlier releases, there are difference in the distribution of services among the nodes of a multirack cluster, depending upon whether the cluster was originally configured as multirack or was a single-rack cluster extended to additional racks. In both cases, prior to this release, the services layout in the first rack is different from that of a single rack cluster.

In Oracle Big Data Appliace 4.14, the distribution of services in a single-rack cluster and in the first rack of a multirack cluster are the same. The services on the second and subsequent racks are now consistent regardless of whether the cluster started out as a single-rack or multirack cluster.

Automated Configuration of Replacements for Failed Operating System Disks and Data Disks

The bdaconfigurediskutility in the Oracle Big Data Appliance Owner' Guide now enables you to configure replacement disks or reconfigure disks with no manual intervention after executing the script. The script supports both OS and data disks.

The Oracle Big Data Appliance Deployment Bundle no Longer Includes the Base Image

The bundle now includes Oracle Big Data Appliance components as RPMs only. The base image is no longer included. There are no changes in the steps you follow to unpack and deploy the bundle.

If you need the base image to bring existing servers up to the minimum release 4.10 base level, see Oracle Big Data Appliance Patch Set Master Note (Doc ID 1485745.1) in My Oracle Support.
