You can change the values of SIZE and MAX by doing one of the following:
  • Overtyping new values on the screen, or
  • Entering DMEM and the SET option, as shown below:


where the following is true:

Syntax Element Description
name name of the block: TRXB, SESB, HRQB, TSCH, HRCB, or BUFx (where x is 1 through 8).
size size of the buffer to be allocated.
max desired maximum value.

CLIv1 uses TSCH and HRCB.

There is one TSCH per CICS transaction, and one HRCB per outstanding Teradata Database request per Teradata session.

There is always a minimum of one HRCB per Teradata session, even if there are no outstanding Teradata requests.

CLIv2 uses TRXB, SESB, and HRQB.

There is one:
  • TRXB per CICS transaction
  • SESB per Teradata session
  • HRQB per Teradata outstanding request.
