Block Level I/O

CA XCOM Data Transport uses record level I/O to read and write records to/from disk. To improve read/write I/O times, the I/O routines now perform block level I/O whenever possible.

The following global parameters support block level I/O:

CACHE_READ_SZ

Specifies the size (in KB) of the cache for reading files.

CACHE_WRITE_SZ

Specifies the size (in KB) of the cache for writing files.
