Reading the content of a sequential data set
To read the content of a sequential data set from an ISequentialDataSet:
ISequentialDataSet sequentialDataSet = ...
// create a BufferedReader wrapping a new DataSetReader using a
// try-with-resources statement
try (BufferedReader reader = new BufferedReader(new DataSetReader(
sequentialDataSet))) {
// read the sequential dataset data using the reader
String record;
while ((record = reader.readLine()) != null) {
// note: non-displayable characters will be output as the
// '\uFFFD' (lozenge) character (displays as '?' in some
// character sets)
System.out.println(record);
}
} catch (DataSetAccessException e) {
// the user does not have access to the sequential dataset
...
} catch (DataSetInUseException e) {
// the sequential dataset is enqueued by another user or job
...
} catch (DataSetMigratedException e) {
// the sequential dataset has been migrated since it was first
// retrieved
...
} catch (DataSetNotFoundException e) {
// the sequential dataset can no longer be found
...
} catch (IOException e) {
// an IO error has occurred reading a line and/or closing the reader
...
}
To read the content of a sequential data set using an IZOSHostConnection:
IZOSHostConnection zosHostConnection = ...
String sequentialDataSetName = ...
// create a BufferedReader wrapping a new DataSetReader using a
// try-with-resource statement
try (BufferedReader reader = new BufferedReader(new DataSetReader(
zosHostConnection, sequentialDataSetName))) {
// read the sequential dataset data using the reader
String record;
while ((record = reader.readLine()) != null) {
// note: non-displayable characters will be output as the
// '\uFFFD' (lozenge) character (displays as '?' in some
// character sets)
System.out.println(record);
}
} catch (DataSetAccessException e) {
// the user does not have access to the sequential dataset
...
} catch (DataSetInUseException e) {
// the sequential dataset is enqueued by another user or job
...
} catch (DataSetMigratedException e) {
// the sequential dataset is migrated
...
} catch (DataSetNotFoundException e) {
// the sequential dataset could not be found or is not a sequential
// dataset
...
} catch (IOException e) {
// an IO error has occurred reading a line and/or closing the reader
...
}
