The RecordOrientedDatasetReaderPattern pattern is used to read data from a z/OS® data set.
Property name | Value | Description |
---|---|---|
PATTERN_IMPL_CLASS | Java class name | Class that implements the RecordOrientedDatasetReaderPattern interface |
DSNAME | Dataset name |
For example, USER216.BATCH.RECORD.OUTPUT |
Property name | Value | Description |
---|---|---|
ds_parameters |
Parameters used to open the data set. |
Default for ZFileRecordOrientedDataReader is rb,recfm=fb,type=record,lrecl=80 and Default for ZFileStreamOrientedByteReader and ZFileStreamOrientedTextReader is rt |
debug |
true or false (default is false) |
Enables detailed tracing on this batch datastream. |
EnablePerformanceMeasurement |
true or false (default is false) |
Calculates the total time spent in the batch data-streams and the processRecord method, if you are using the GenericXDBatchStep. |
EnableDetailedPerformanceMeasurement |
true or false (default is false) |
Provides a more detailed breakdown of time spent in each method of the batch data-streams. |
file.encoding |
Encoding of the file. |
For example, 8859_1. |
