This application is an interface process that implements the delivery
of new files (FITS, PAF, LOG, OTHERS) from the On-line Archive System
(OLAS) to any host.
dhsSubscribe uses the OLAC (On-Line Archive Client) class to
communicate with the OLAS Data Handling Server (DHS).
DhsSubscribe could run a user defined UNIX command for each new file
received and apply a renaming schema to each FITS file received.
OPTIONS
The options are described below:
-subscribe <user@host:dir>
Indicate how to rcp messages to the DHS. If not specified
the environment variable $DHS_CONFIG is used. If that is
not set dhsSubscribe will exit with an error message.
-dhshost <host>
Specify the machine running DHS. Its use is deprecated, as the same
information can be given using the option -subscribe or
the environment variable DHS_CONFIG. If both -subscribe and -dhshost
are used, the latter will be ignored.
-dhsid <string>
Indicate the id used by the Data Handling Server.
-dhsdata <dir>
Specify the directory in which to place incoming new frames
(mmap'ed files). If this is not specified, the environment
variable DHS_DATA is used. If that is not set, the current
directory is used. The file name of a new frame is the date
and time string corresponding to the arrival time of the frame
to the archive system and it is the same for all
subscribers. The format is
YYYY-MM-DD/XXX.YYYY-MM-DDThh:mm:ss.mss.fits
or
YYYY-MM-DD/<sourceFilename>
where
YYYY-MM-DD/
corresponds to the date of the
beginning of the night (noon UTC)
of the MJD-OBS keyword's value
XXX
corresponds to the instrumentation ID
(e.g. UT1 )
YYYY-MM-DDThh:mm:ss.mss.fits
corresponds to the MJD-OBS keyword's value
<sourceFilename> corresponds to the original Filename for files
otehr than FITS
