Requirements to use z/TPFDF encryption support

To use z/TPFDF encryption support, the z/TPFDF database must meet all of the following requirements.

  • The file must be a z/TPFDF file (that is, ACPDB=YES is specified or implied on the DBDEF macro).
  • The file must be an R-type file.
  • The file must use the default trailer size, which means that the TRS parameter is not specified on the DBDEF.
  • The RBV algorithm value cannot be #TPFDB0D.
  • The file cannot be a z/TPFDF B+Tree node file, which means that the NODE=YES parameter cannot be specified on the DBDEF.
  • The FVN parameter must be 0 or not specified on the DBDEF.

In addition, the &ACPDBFS symbol in the DBLCL macro must be set to 1.
