# TIBCO Accelerator Parameters

You must supply the TIBCO Accelerator transfer parameters when you use the Accelerator (ACC) technology to do a transfer.

Parameter (Alternate Specification) | Description
--- | ---
Accelerate (ACC) | Defines whether to conduct file transfers using Accelerator technology. The valid values are: N: does not use the Accelerator technology for a transfer. Y: forces a transfer to be conducted using Accelerator technology, so you can speed up data transfer over IP networks with high latency.
ACCCompression (ACCC) | Defines whether to compress the data transferred through Accelerator. The valid values are: N: no compression. Y|Best: best balance between speed and compression quality. Default: highest compression with slightly lower speed. Fast: lower compression but with fast speed. Note: Accelerator uses a proprietary compression compatible with ZLIB compression.
ACCEncryption (ACCE) | Defines whether to encrypt the data transferred through Accelerator. The encryption type is 256-bit Blowfish encryption. The valid values are N or Y.
ACCHost (ACCH) | Defines the IP address or host name of Accelerator server. The valid values are N, hostname, or IP _address. Note: A host value defined on the command line or in a transfer template overrides the ACCHost value configured in config.txt file. If the value defined on the command line or in a transfer template is N, and you have Accelerate set to Y, the value configured for ACCHost in config.txt file is used. For more information, see Configuration Parameters.
ACCMaxSpeed (ACCMAX) | Defines the maximum speed, in kilobytes per second, for transfers through Accelerator. You can set this parameter on the command line or in a transfer template. The valid values are from 256 to 1000000. For more information, see Transfers Using Templates.
ACCPort | Defines the port number on which the platform server listens for transfers using the Accelerator technology. The valid values are N or port_number. Default value is 9099. Note: A port number defined on the command line or in a transfer template overrides the ACCPort value configured in config.txt file. If the value defined on the command line or in a transfer template is N and you have Accelerate set to Y, the value configured for ACCPort in config.txt file is used. For more information, see Transfers Using Templates and Configuration Parameters.
ACCProtocol (ACCP) | Defines the transmission protocol for file transfers through Accelerator server. The valid values are: TCP: Transmission Control Protocol UDP: Accelerator server enhanced version of User Datagram Protocol PDP: Parallel Delivery Protocol
