  1. For automatic in-doubt resolution for Two-phase commit processing, configure the CICS system to be able to do a warm start.
  2. Delete or comment out the Teradata Director Program command, DISABLE IRF, in the TDPPARM data set. This is described in TDPPARM Settings for Two-Phase Commit Processing. After the DISABLE IRF command is eliminated, the two TDP-internal sessions necessary for Two-phase commit processing are logged on automatically upon TDP startup.
  3. Authorize CICS to Teradata Director Program in the TDPPARM data set.
  4. Create new entries in the TDPPARM data set for each CICS system that uses Two-phase commit protocol. The entries, which authorize each CICS system to Teradata Director Program, have the following form:
    AUTHORIZ cicsjob RESOLVE
    where cicsjob specifies the jobname for the CICS system.
