FTP Replacement / Electronic Business Using XML
ERCOT provides a client-server-based approach to allow market participants to send, receive and download files to/from the ERCOT server. The scripts for SEND, RECEIVEALL and DOWNLOAD form the "client" side of the package. The "server" side of the package, performing ERCOT server-related file transport functions, resides at ERCOT. The scripts contain the functionality needed to encrypt/sign, decrypt/verify, send (push) and receive (pull) data files.
These scripts replace the FTP scripts originally provided to market participants.
After constructing valid command lines using the scripts below, market participants will be able to send and receive data from ERCOT:
- SEND - Used to upload files from the market participant to the market participant’s mailbox on the ERCOT server
- RECEIVEALL - Used to pull files from the market participant's mailbox on the ERCOT server
- DOWNLOAD - Used to pull a single file that has been archived on the ERCOT server.
