7.3.1 Java-Based Tools Issue on Oracle Linux 6 and Red Hat Enterprise Linux 6
Java-based tools such as Oracle Universal Installer, Oracle Database Configuration Assistant, and Oracle Enterprise Manager Configuration Assistant cannot display
non-English multibyte character language messages on Oracle Linux 6 (32-bit and 64-bit) and Red Hat Enterprise Linux 6. For example, languages like Japanese,
Chinese, Korean, and so on, are not displayed by the Java-based tools on Oracle Linux 6 (32-bit and 64-bit) and Red Hat Enterprise Linux 6.
Workaround:
Download patch 12991286 from the My Oracle Support website and follow the
instructions in the README file of the patch.
This issue is tracked with Oracle bug 12991286.

7.3.2 Time Zone Issue with Oracle Linux 6
When Oracle Grid Infrastructure is installed on Oracle Linux 6, the logs may show incorrect time zone information if the system Timezone string contains a space. This
can be checked through the /etc/sysconfig/clock file.
Workaround:
You must use the following workaround on the local node (the node on which Oracle
Universal Installer is running) of a cluster before starting Oracle Grid Infrastructure
installation:
Modify the /etc/sysconfig/clock file to replace any space with an underscore (_) in
the time zone name. For example, Los_Angeles instead of Los Angeles.
Oracle recommends that you apply this workaround on all the nodes of a cluster so
that if Oracle Universal Installer is run at a later time from any other node, the time
zone is correctly calculated.

7.3.3 Linux Kernel Issue
Due to a bug in Linux version 2.6.39, after a system failure or an offline Oracle ACFS, if the system's dirty page ratio is not high enough to trigger a flush using the dirty_
background_ratio tunable parameter, then unexpected loss of data or extraneous data may occur at the ends of Oracle ACFS files that cached data at the time of the system
failure or the offline Oracle ACFS.
Workaround:
Refer to the Unbreakable Enterprise Kernel 2.6.39 Errata, kernel version 2.6.39-400.5,
for more information regarding the fix.
This issue is tracked with Oracle bug 16981677.
