The microprocessors for the SPARC M8 and SPARC M7 servers offer new co-engineered hardware and software capabilities that enable applications to run with the highest levels of security, reliability, and speed. This functionality is called Oracle Software in Silicon.
Software in Silicon features include:
Silicon Secured Memory – These APIs can be used, for example, to enable the detection of memory corruption issues, thereby enhancing applications data integrity (ADI) when an application uses its own custom memory allocator. (The ADI feature is not supported for use with Kernel Zones at this time.)
With this feature enabled, an error is likely to be raised if an application tries to access memory to which it should not have access.
For more information, refer to the adi(3C), adi(2), memcntl(2), mmap(2), and siginfo(3HEAD) man pages.
Data Analytics Accelerator (DAX) – Coprocessors perform query-related operations directly through the hardware, which improves Oracle Database performance. You can use DAX hardware acceleration for Oracle Database 12c in-memory database operations. (The DAX feature is not supported for use with Kernel Zones at this time.)
For more details on ADI, refer to the Oracle Solaris 11.3 documentation.
To use DAX, you must configure the Oracle Database 12c in-memory feature. For instructions, refer to “Using the In-Memory Column Store” at:
