  Currently users are unable to make use of the Large Block
  Interface (LBI) during the creation of utility
  sequential data sets via the TEMPLATE utility. LBI allows for
  better performance as it can help decrease CPU utilization
  and the elapsed time for utilities. LBI also allows
  utilities to handle much larger blocks with BSAM and allows
  customers to increase their block size for data sets. LBI is
  useful mainly when creating new data sets on tapes.
  But to make use of LBI today, users are required to update
  their DFSMS data class. In order to provide more flexibility
  to users of the TEMPLATE utility, the TEMPLATE utility control
  statement will be enhanced to provide the ability to
  specify the BLKSZLIM option.
  

Problem conclusion

Temporary fix

Comments

• The TEMPLATE utility will be enhanced to support the
  specification of BLKSZLIM for FL500. Currently, the
  TEMPLATE utility does not allow the specification of
  BLKSZLIM for the creation of utility sequential data sets.
  System Determined Block Size (SDB) is used by TEMPLATE
  processing to setup the optimal block size. With the
  BLKSZLIM keyword, it will tell z/OS that the user has
  requested to use the large block interface and it would
  use the BLKSZLIM as the upper limit when it uses SDB to
  determine the optimal block size.

  BLKSZLIM integer
  Specifies the upper limit for the block size for the data
  set if the system determines the block size for the data
  set. The minimum value is 32760 or 32K. The maximum value
  is 2,147,483,648 (coded without the commas) or 2G.
  Use the BLKSZLIM option to set the upper limit on a data
  set's block size if the system determines the block size
  for the data set.
  For additional information regarding the BLKSZLIM parameter
  in regards to usage and limitations, please refer to IBM's
  z/OS MVS JCL Reference.
