Oracle Build steps

Using Ubuntu 14.04 - intructions dated for 21/09/2016 (Was built on AWS in an r3.xlarge These actions were done against 0.5 checkout)

• Setup Oracle Instant Client - https://help.ubuntu.com/community/Oracle%20Instant%20Client download from http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html.

The following RPM's and upload them to the server:

• oracle-instantclient12.1-basic-12.1.0.2.0-1.x86_64.rpm
• oracle-instantclient12.1-devel-12.1.0.2.0-1.x86_64.rpm

alien -i oracle-instantclient12.1-basic-12.1.0.2.0-1.x86_64.rpm
alien -i oracle-instantclient12.1-devel-12.1.0.2.0-1.x86_64.rpm

• Install Cuda - http://www.r-tutor.com/gpu-computing/cuda-installation/cuda7.5-ubuntu

wget http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1404/x86_64/cuda-repo-ubuntu1404_7.5-18_amd64.deb
sudo dpkg -i cuda-repo-ubuntu1404_7.5-18_amd64.deb 
sudo apt-get update
sudo apt-get install cuda
export CUDA_HOME=/usr/local/cuda-7.5 
export LD_LIBRARY_PATH=${CUDA_HOME}/lib64 
 
PATH=${CUDA_HOME}/bin:${PATH}
export PATH
echo "/usr/lib/oracle/12.1/client64/lib" > /etc/ld.so.conf.d/oracle-client-12.1.conf
ldconfig

• Build sysbench Use the following configure option to build with Oracle support:

./configure --with-oracle="/usr/lib/oracle/12.1/client64"

Run the following commands to allow sysbench use the full number of cores:

sudo sh -c 'for x in /sys/class/net/eth0/queues/rx-*; do echo ffffffff> $x/rps_cpus; done'
sudo sh -c "echo 32768 > /proc/sys/net/core/rps_sock_flow_entries"
sudo sh -c "echo 4096 > /sys/class/net/eth0/queues/rx-0/rps_flow_cnt"
