Waveform archive server


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

  • fdsnws 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.

Module Configuration


scwfas inherits global options.


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.


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().


Default: -1

Type: int

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


Default: 8080

Type: int

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


Default: http://localhost:8080/fdsnws

Type: string

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


Default: 0

Type: int

Unit: s

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

Command-Line Options

scwfas [options]


-h, --help

Show help message.

-V, --version

Show version information.

--config-file arg

Use alternative configuration file. When this option is used the loading of all stages is disabled. Only the given configuration file is parsed and used. To use another name for the configuration create a symbolic link of the application or copy it. Example: scautopick -> scautopick2.

--plugins arg

-v, --v

Increase verbosity level (may be repeated, eg. -vv).

-q, --quiet

Quiet mode: no logging output.

--print-component arg

For each log entry print the component right after the log level. By default the component output is enabled for file output but disabled for console output.

--component arg

Use syslog logging backend. The output usually goes to /var/lib/messages.

-l, --lockfile arg

Path to lock file.

--console arg

Send log output to stdout.


Execute in debug mode. Equivalent to --verbosity=4 --console=1 .
