The microprocessors for the SPARC T7 series servers offer co-engineered hardware and software capabilities that enable applications to run with the highest levels of security, reliability, and speed. This functionality is called as Oracle Software in Silicon.
Software in Silicon features include:
Silicon Secured Memory – detects common memory access errors including:
Buffer overflows
Unallocated or freed memory access errors
"Double free" memory access errors
Stale pointer memory access errors
With Silicon Secured Memory enabled, an error is likely to be raised if an application tries to access memory to which it should not have access. This feature enhances application data integrity (ADI). (The Silicon Secured Memory feature is not supported for use with Kernel Zones at this time.)
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 Silicon Secured Memory, 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:
