One way is to use a Java stored procedure, this can then be called from a map or a process flow. The Java stored procedure will use the Zip capabilities in Java to do what you need. For example you will need the following procedure and you will have to grant privileges for your file to ZIP and the entire directory for zipping into (since the file name will be dynamic):
For example grant YOURSCHEMA (change to your tgt schema) read on your extract directory where your file to zip is and write on your zips directory (where the zips will go);
exec dbms_java.grant_permission('YOURSCHEMA', 'SYS:java.io.FilePermission', 'c:\staging\extracts\*','read');
exec dbms_java.grant_permission('YOURSCHEMA', 'SYS:java.io.FilePermission', 'c:\staging\zips\*', 'write' )
You can then create your procedure which you can invoke
CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "otnZipFile"
AS
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
public class otnZipFile
public static void zipFile(String zip, String filename)
byte[] buf = new byte[1024];
try {
String outFilename = zip;
ZipOutputStream out = new ZipOutputStream(new FileOutputStream(outFilename));
FileInputStream in = new FileInputStream(filename);
out.putNextEntry(new ZipEntry(filename));
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
out.closeEntry();
in.close();
out.close();
} catch (IOException e) {
create or replace PROCEDURE zip_file(
dir IN VARCHAR2,
file_name IN VARCHAR2) IS
LANGUAGE JAVA NAME 'otnZipFile.zipFile(java.lang.String, java.lang.String)';
For example here I zip a file MYCSV.csv into the zip file MYZIP.zip
exec zip_file('c:\staging\zips\MYZIP.zip', 'c:\staging\extracts\MYCSV.csv');
