Requirements and Limitations for Finding RID Fields

Requirements and Limitations for Finding RID Fields

When you use the createdatamaps utility to find RID fields, the following requirements and limitations apply:
  • The utility determines the field or fields that are most likely to be RID fields and associates the RID values with the record layouts that are the best match. Be sure to open the data map in the PowerExchange Navigator and confirm or edit the results.
  • The utility can find RID fields only for sequential or VSAM data sources on z/OS.
  • Both the data and the metadata must reside on the z/OS machine. When you start the utility from the command line, include the
    -pwxLocation
    parameter to specify the location of the PowerExchange Listener.
  • The same user ID and password are required to access both data and metadata. When you start the utility from the command line, include the -pwxUserName and -pwxPassword parameters.
  • A copybook can define variable-length arrays and groups. For example, a copybook might include the following line:
    05 ARRAY OCCURS 3 DEPENDING ON ITEMCT PIC X(5).
    The following limitations apply to variable-length arrays and groups:
    • Nested variable-length arrays or groups are not supported.
    • If the metadata is variable length, the createdatamaps utility assumes that the record format is variable (RECFM=V).
    • An RID field cannot follow a variable-length array or group.
