Apply the file output facility for BLOB data to reduce the amount of memory required during BLOB data search.

This facility is effective in reducing the memory size required for client programs and the memory size required for the communication buffer used in server-client communication. However, applying this facility also increases the disk input/output operations that take place during file output. Therefore, be sure to consider both the required memory size effects and the disk input/output effects before you use the file output facility for BLOB data.
