## Setup Environment on a clean machine

### Windows
Install Visual Studio 2015 before running the following commands. Make sure C++ tools are enabled.
Run `cmd` as administrator.

    powershell
    Set-ExecutionPolicy Unrestricted
    .\setup_env_windows.ps1 <PHP_VERSION - 7.x.x> <PHP_THREAD - ts or nts> <Absolute path to driver source folder> <ARCH - x86 or x64>    

### Ubuntu 16
    sudo env “PATH=$PATH” bash setup_env_unix.sh Ubuntu16 <PHP_VERSION - 7.x.x> <PHP_THREAD - ts or nts> <Absolute path to driver source folder>
### RedHat 7
    sudo env “PATH=$PATH” bash setup_env_unix.sh RedHat7 <PHP_VERSION - 7.x.x> <PHP_THREAD - ts or nts> <Absolute path to driver source folder>
### Sierra
`brew` cannot be run with `sudo` on Sierra. Either enable passwordless `sudo` on the machine or enter the password when prompted. 

    bash setup_env_unix.sh Sierra <PHP_VERSION - 7.x.x> <PHP_THREAD - ts or nts> <Absolute path to driver source folder>
## Run benchmarks

### 1. Modify lib/connect.php with the test database credetials
### 2. Execute run-perf_tests.py. 
The script must be executed with `sudo python3` because to enable pooling it needs to modify odbcinst.ini system file. As an improvement, the location of the odbcinst.ini file can be changed so that, sudo is not requiered. 
    
    py.exe run-perf_tests.py -platform <PLATFORM> -iterations <ITERATIONS> -iterations-large <ITERATIONS_LARGE> -result-server <RESULT_SERVER> -result-db <RESULT_DB> -result-uid <RESULT_UID> -result-pwd <RESULT_PWD>

`-platform` - The platform that the tests are ran on. Must be one of the following: Windows10, WidnowsServer2016 WindowsServer2012 Ubuntu16 RedHat7 Sierra  
`-iterations` - The number of iterations for regular tests.  
`-iterations-large` - The number of iterations for the tests that fetch large data. Usually set to 1.  
`-result-server` - The server of result database. It is assumed that, the result database already setup before running the tests.  
`-result-db` - Database name. With the current result database setup files, this should be set to `TestResults`  
`-result-uid` - Result database username  
`-result-pwd` Result database password
