• To use startup options.

• Using the startup/shutdown scripts:

/etc/init.d/scspproxy start

/etc/init.d/scspproxy stop

Use the startup/shutdown scripts if the Proxy is installed on a CSN, or if it is installed on RHEL

and you do not want to use optional startup options.

• You can start the Proxy using proxyservice.py under any of the following circumstances:

Run the following command from the directory where the install file was unzipped (or from any

location if you have configured your Python path to point to the installed location):

python2.5 proxyservice.py options

where options are discussed in the following table.

proxyservice.py startup option

--staticlocator

--cfgfile path-to-scspproxy.cfg

--pidfile path-to-scspproxy.pid

To validate if the proxy is running in front of a DX Storage cluster, enter the Proxy's IP address and

port in a web browser's location or address field. If you see a DX Storage status page the proxy is

working correctly.

2.3.1. Validation Mode

In addition to the basic validation included in the DX Storage SDK, the SCSP Proxy includes a

validation mode that provides validation for incoming SCSP requests. This validation checks the

syntax for common operations like adding query arguments and creating lifepoint headers. The

SCSP Proxy does not discern between clients created using the DX Storage SDK and those that

were created without it.

Validation mode and execution mode are mutually exclusive. Requests are not sent to DX Storage

while in validation mode but are instead analyzed by the Proxy for a response. If a query fails

validation, it returns an error describing the reason for the failed validation.

Successful status codes in validation mode follow:

• 200 for GET, HEAD, and DELETE

• 201 for POST, PUT, COPY, and APPEND

Errors are returned as one of the following codes:

• 400 for any validation error for a known method

Meaning

Start the Proxy and use the static locator.

Access the Proxy configuration file from the

specified location.

Specify the location of the Proxy service

Process Identifier (PID) file.

The default location is /var/run/

scspproxy.pid.
