fblksize

CFTFILE

[FBLKSIZE = { see table below | n}]   {0...32768}

According to TYPE/ OS

Defines the block size, in bytes, of the file to be created.

The table below indicates, for each system, the default value supported according to the type of file to be created.When the default value of the block size of the file to be created is "no" in the following table, the FBLKSIZE parameter does not need to be defined.

CFTRECV, RECV

[FBLKSIZE = n ]              {0..62563}

This parameter, in bytes, controls the "blocking factor" of the receiver file records: according to the system, it defines the disk block size and/or the file input/output buffer size.

For protocols other than PeSIT, CFT profile, if this parameter is not defined, its value is set as follows: 

  • For fixed format files: this value equals the largest multiple of FLRECL which is less than the constant (related to the track length) defined on installation (default value: 19069), or FLRECL if FLRECL is greater than this constant
  • For variable format files: this value equals the constant (related to the track length) defined on installation of the Transfer CFT in a z/OS environment (default value: 19065), or to FLRECL + 4 if FLRECL is greater than this constant
  • For undefined format files: this value is equal to 32760

CFTSEND, SEND

[FBULKSIZ = n]   { 0...65536}

Block size of sent file.

Typically you do not need to define this parameter as Transfer CFT is able to locate the value for the file to be sent. This real value is then taken into account when activating the transfer.
