Runtime Considerations

This section provides general information that you need to consider while running the Oracle Solaris 11.4 OS.

Java Recommendations

The Java environment delivered in Oracle Solaris 11.4 is Java 8.

/usr/ccs/bin Is a Symbolic Link to /usr/bin

The /usr/ccs/bin directory is a symbolic link to /usr/bin.

Because of this change, for example, the /usr/ccs/bin:/usr/gnu/bin:/usr/bin path in the PATH environment variable is now equivalent to /usr/bin:/usr/gnu/bin. This change might result in changes to the utilities that are found by PATH searches.

If the /usr/ccs/bin change causes issues in locating GNU utilities, the PATH environment variable should be rearranged to place /usr/gnu/bin earlier than /usr/bin or utilities should be invoked with a full path.

GNOME Always Starts in a UTF-8 Locale

Because GNOME 3 only supports UTF-8 locales, when the system locale is not a UTF-8 locale, the GNOME session in Oracle Solaris runs in the corresponding UTF-8 locale. For example, if the system locale is fr_FR.ISO8859-1, GNOME desktop will run with fr_FR.UTF-8.

Keyboard Input Language Support

Keyboard input support for some languages has been dropped in Oracle Solaris 11.4 as described in “Desktop Input Components” in End of Feature Notices for Oracle Solaris 11.

To enter input in a language that is not supported, on the Oracle Solaris 11.4 system, install language engines from third party sources.

IP Filter is Not Supported in Oracle Solaris 10 Zones

Because IP Filter is not available in Oracle Solaris 11.4 (see “IP Filter” in End of Feature Notices for Oracle Solaris 11), IP Filter also is not supported in Oracle Solaris 10 zones running on Oracle Solaris 11.4 systems.
