Grid Infrastructure was installed to use Oracle ASM for DATA and LOG disk groups.
Oracle database processes run in 2 processor sets where each pset is configured with 48 HW strands.
Each process runs in the FX class using /usr/bin/priocntl -s -c FX -i pid PID.
Oracle Log Writer runs in a processor set containing 8 HW strands from a single core,
and runs in RT class using /usr/bin/priocntl -s -c RT -p 1 -i PID.
Oracle DB writers run in a processor set containing 8 HW strands from a single core.
The remaining two cores were used for HBA and network interrupts.

NIC Tuning for driver and emulator communication:
ndd -set /dev/ixgbe[3/1] intr_throttling 2000

Configuration Notes:
Two application server instances were hosted in the global zone
The application server instance's processes were bound to separate processor sets where each pset consisted of 58 HW strands
using /usr/sbin/psrset -b PSET PID. Interrupts were enabled on remaining HW strands in the default processor set.
Each application server instance on the system was configured with 2 subnets.
2x 10 Gbit NIC ports were used for driver requests.
2x 10 Gbit onboard NIC ports were used for JDBC access where each NIC was dedicated to one application server instance.
Interrupts from the Network controllers were configured across the
processors in the default set using the /usr/sbin/pcitool utility.
Stop intrd.

Mirrored SSDs were used for JMS and server log files.

ndd -set /dev/tcp tcp_naglim_def 1

Configuration Notes:
1x 10 Gbit NIC port used for DNS requests.
2x 10 Gbit onboard NIC ports were for JDBC access.
Interrupts from the HBAs & Network controller were configured across the
processors in the default set using the /usr/sbin/pcitool utility.
Stop intrd.

External storage configuration:
1x Oracle Server X6-2L configured with 2x 3.2 TB NVMe PCIe SSDs,
2x 600GB SAS-3 Disks, and 1x Sun 16Gb FC Dual Port HBA for the database files.
1x Oracle Server X6-2L configured with 14x 600 GB disks, 1x Sun 16Gb FC

Configuration Notes:
Four application server instances were hosted in 4 separate Solaris Zones.
The 4 zones were bound to separate processor sets where each pset
consisted of 10 cores using /usr/sbin/psrset -b PSET PID.
