The Teradata Director Program parameter (TDPPARM) data set is specified in the JCL that starts TDP. The TDPPARM data set contains a list of TDP commands that are executed when TDP is started. These commands assign defaults and initialize TDP. Each TDP can have its own TDPPARM data set.

Two examples of the TDPPARM data set are members in dbcpfx.PROCLIB, named TDPCMD0 and TDPCMD1. The TDPCMD0 member is called by the TDP0 job, which is executed when TDP is started. In the same way, the TDPCMD1 member is called by the TDP1 job. Both the TDP0 and TDP1 jobs are located in dbcpfx.PROCLIB.

  1. Make sure that the data set name is included in the TDPPARM DD statement of the JCL that starts TDP.
  2. Add or change the commands in the TDPPARM data set according to the requirements at your site. For information on the above commands and other TDP commands that can be used in the TDPPARM data set, see Teradata® Director Program Reference (B035-2416).
  3. To enable Two-phase commit processing at your site, delete or comment out the DISABLE IRF command in the TDPPARM data set.

    When Two-phase commit processing is enabled, the two required TDP internal sessions are logged on automatically upon TDP startup.
