Class ZipDatasets

java.lang.Object
com.ibm.jzos.sample.ZipDatasets
public class ZipDatasets extends Object
A sample Java main class that can be invoked to create a Zip archive from one or more datasets or PDS members. Datasets are treated as text and converted from EBCDIC to ASCII (ISO8859-1) or to the specified target codepage.

Details on the input arguments to this class are available by executing the main method with no arguments. (see usage())

Example: Zip several partitioned datasets to a Unix zip file: 

com.ibm.jzos.sample.ZipDatasets test.zip sys1.proclib(asm*) hlq.**.jcl

Example: Zip all datasets matching two patterns to a dataset: 

com.ibm.jzos.sample.ZipDatasets //hlq.backup.zip payroll.*.data gl.**.dat*

Example: Zip data using DDs and input and output: 

com.ibm.jzos.sample.ZipDatasets //DD:ZIPOUT //DD:INSEQ1 //DD:INPDS1 //DD:INPDS2(FOO*)

Since:
2.3.0
