The following section contains information about issues related to Oracle Database 12c and associated products:

• DBCA Displays Incorrect Memory of the Host Server

• Oracle R Enterprise Fails Due to Libtiff Library Version Mismatch

• Oracle Grid Infrastructure Installer Prerequisite Check May Fail Due to Incorrect RPM Versions

When creating a database on Linux Container, Database Configuration Assistant (DBCA) incorrectly shows the available memory of the host server instead of the Linux Container on the Specify Configuration Options page. When you choose to allocate the percentage of memory based on the value shown, the database creation may fail in the case where total consumable memory for that Linux Container is less than the allocated memory.

Workaround:

You must allocate physical memory for the database according to the configuration of the Linux Container system.

This issue is tracked with Oracle bug 21546793.

The Cairo package in Oracle R Enterprise fails to load on SUSE Linux Enterprise Server 12 when the libtiff.so.3 version is missing.

Workaround:

Create a symlink for libtiff.so.3 from libtiff5.so.5.

This issue is tracked with Oracle bug 24939744.

The Oracle Grid Infrastructure installer prerequisite check for 12c Release 2 (12.2) may fail if you use the e2fsprogs-1.42.8-1.0.2 (x86_64) and e2fsprogs-libs-1.42.8-1.0.2 (x86_64) packages.

Workaround:

1. Ensure that you meet the following minimum RPM version requirements:

   e2fsprogs-1.41.12-14.el6 (x86_64) or later

   e2fsprogs-libs-1.41.12-14.el6 (x86_64) or later

2. Ignore the e2fsprogs and e2fsprogs-libs failure notifications and proceed with the Oracle Grid Infrastructure installation.

This issue is tracked with Oracle bug 25232262.
