Oracle Portability and Compatibility Guarantee

Oracle Solaris has maintained binary compatibility between operating system releases for nearly a

decade, enabling existing Oracle Solaris applications to run unmodified on Oracle Solaris 11. This

means that Oracle Solaris applications developed over many years will run on Oracle Solaris 11

unchanged, taking full advantage of new and advanced Oracle Solaris features.

The Oracle Solaris Source Code Guarantee provides assurance that C and C++ applications developed

and successfully compiled to run on either a SPARC or x86 platform will successfully compile and run

on both platforms. Through Oracle's commitment to choice, organizations can confidently develop

and deploy applications on whatever platform best suits their needs now and into the future. This

guarantee helps protect long-term investments in software development, training, and IT staff skills.

Similarities and Differences Between Oracle Solaris and Linux

The Single UNIX Specification (SUS) is an industry-standard description of C-language program and

user command interfaces for a standard UNIX operating system. The SUS was developed to ensure

that a program developed in one UNIX operating system would run in a somewhat different UNIX

operating system. The specification is owned by The Open Group, an industry group that oversees

UNIX certification and branding.
