Running the Integration Service in ASCII Data Movement Mode

Running the Integration Service in ASCII Data Movement Mode

When all character data processed by the Integration Service is 7-bit ASCII or EBCDIC, configure the Integration Service to run in the ASCII data movement mode. In ASCII mode, the Integration Service uses one byte to store each character. When you run the Integration Service in Unicode mode, it uses two bytes for each character, which can slow session performance.
