Allow Member State users to initiate file transfers between ECMWF and Member State servers. The ECaccess Server will spool the ECMWF file specified by the source parameter in the user's ECtrans transfer queue: if the connection between the ECMWF and Member State gateways is down or if any error occurs, the file will be kept in the spool area at ECMWF and you can resume the transfer through the web interface or with the ecaccess-ectrans- restart command. If required the transfer can be retried automatically (see the -retryCount and -retryFrequency options to tailor the retry mechanism). The -reject, -append, -resume and -overwrite options are mutually exclusive and determine what to do if there is an existing target file. The -mailTo option specifies an email address to be notified in case of a successful (option -onSuccess) and/or a failed transfer (option -onFailure). When a request has been spooled successfully, an ectrans-id is returned immediately. The ectrans-id can be used to reference the transfer, using the web interface or with the ecaccess-ectrans-delete, ecaccess-ectrans-list or ecaccess-ectrans-restart commands.
association-name[@protocol] The ECtrans Association with optionaly the name of the protocol to use. source Name of the file at ECMWF to spool in ECtrans.
-gateway name This is the name of the ECaccess Gateway where the ECtrans Association association-name is defined. It is by default the Gateway you are connected to. In order to get the name of your current Gateway you can use the ecaccess-gateway- name command. When using the commands at ECMWF the default Gateway is always "ecaccess.ecmwf.int". -target file-name Defines the target file-name (default: same as source). -retryCount number Defines the number of retries (default: 144). -retryFrequency frequency Defines the frequency of retries in seconds (default: 600 seconds). -priority priority Defines the transmission priority 0-99 (default: 99). -lifeTime duration Defines the lifetime of the request (default: 7 days). The duration is specified in [w]eeks, [d]ays, [h]ours, [m]inutes or [s]econds (e.g. 1w or 2d). -mailTo email Defines the target email address (default: <user-id>@ecmwf.int). -onSuccess Allow sending a mail when the transfer is successful. -onFailure Allow sending a mail when the transfer has failed. -onRetry Allow sending a mail when the transfer is retried. -deleteSource Allow deleting the original source file once it is safe in the spool. -keep Allow keeping the request in the spool until the duration specified in the -lifeTime option has passed. By default a successful transfer is removed from the spool. -reject Allow failing if there is an existing target file (default). -append Allow appending if there is an existing target file. -resume Allow resuming if there is an existing target file. -overwrite Allow overwriting if there is an existing target file. -maximumDuration duration Define the maximum transfer duration. The duration is specified in [w]eeks, [d]ays, [h]ours, [m]inutes or [s]econds (e.g. 10m or 1h). A value <=0 will deactivate the feature (default: 12h). -minimumDuration duration Allow setting the duration before to control a transmission (e.g. for the first 10 minutes ECtrans don't try to check the transfer rate, which allow not to enforce some minimum transfer rates for very small files). The duration is specified in [w]eeks, [d]ays, [h]ours, [m]inutes or [s]econds (e.g. 30s or 10m). A value <=0 will deactivate the feature (default: 10m). -minimumRate rate Allow setting a minimum transfer rate for a transmission (expressed in bytes/s). This is an average value, not the transmission rate at one particular moment in time (e.g. if a big file is stuck for 5 minutes but then transmit much faster later on then it will not be interrupted as long as the overall transfer rate is above the minimum). A value <=0 will deactivate the feature (default: 10240). -version Display version number and exits. -help Print a brief help message and exits. -manual Prints the manual page and exits. -retry count Number of SSL connection retries per 5s to ECMWF. This parameter only apply to the initial SSL connection initiated by the command to the ECMWF server. It does not apply to all the subsequent requests made afteward as it is mainly targeting errors that can happen from time to time during the SSL handshake. Default is no retry. -debug Display the SOAP and SSL messages exchanged.
ecaccess-ectrans-request -lifeTime 2d -overwrite -onFailure -onRetry test@genericFtp ec:test.txt Request a file transfer of the ec:test.txt file to the default gateway with the association test and the protocol genericFtp. If the target file already exists then the original file is deleted. If the transfer is retried or fail then an email is sent to the default email address (<user-id>@ecmwf.int). After 2 days the file is removed from the spool (whatever the status of the transmission is). ecaccess-ectrans-request -minimumDuration 10m -maximumDuration 35m -minimumRate 8192 test@genericFtp ec:test.txt After 10 minutes ECtrans will start to control the transfer rate. If after 35 minutes the file is still not transmitted or if at a certain point in time the average transmission rate is less than 8Kbytes/s then the transmission will be canceled. If canceled, the transmission will be retried 144 times (with a 10 minutes interval).
