**Waveform archive server**


Description
===========

The waveform archive server is a small application that serves a local
SDS archive via different protocols. Currently there are two implementations:

* :ref:`fdsnws dataselect <sec-dataSelect>`

  * dataselect/1/query
  * dataselect/1/version
  * dataselect/1/application.wadl

* Arclink (deprecated)

This application is meant to share data with trusted computers in a fast and
efficient way. It does not require inventory information and supports wildcards
on each level.

All data are forwarded unrestricted. There are no options to add restriction
checks or user authentication.

| :file:`etc/defaults/scwfas.cfg`
| :file:`etc/global.cfg`
| :file:`etc/scwfas.cfg`
| :file:`~/.seiscomp/global.cfg`

scwfas inherits :ref:`global options<global-configuration>`.



.. confval:: handlerSDS

   Type: *string*

   Defines an alternative SDS archive handler. This is the name
   of an RecordStream interface that can be loaded via a plugin.
   If not given, an internal implementation will be used.


.. confval:: filebase

   Default: ``@ROOTDIR@/var/lib/archive``

   Type: *string*

   The filebase of the SDS archive. If an alternative archive
   handler is defined by \"handlerSDS\", this value serves
   as input to setSource\(\).


.. confval:: arclink.port

   Default: ``-1``

   Type: *int*

   The server port for Arclink connections. \-1
   deactivates the Arclink server. The standard Arclink port is
   18001.


.. confval:: fdsnws.port

   Default: ``8080``

   Type: *int*

   The server port for FDSNWS connections. \-1
   deactivates the FDSN Web server.


.. confval:: fdsnws.baseURL

   Default: ``http://localhost:8080/fdsnws``

   Type: *string*

   The base URL of the FDSN Web service that is
   given in the WADL document.


.. confval:: fdsnws.maxTimeWindow

   Default: ``0``

   Type: *int*

   Unit: *s*

   The aggregated maximum time window \(seconds\)
   for all requested streams. A value of 0 will deactive
   any restriction.
