If you need to capture SQL statements to replay in another instance you can turn trace on and capture in the trace files located in the udump folder.
– turn timing on.
alter session set timed_statistics=true;
– set to unlimited otherwise you may get an incomplete trace file when dump file size limit is reached.
alter session set max_dump_file_size=unlimited;
alter session set events ’10046 trace name context forever, level 12′;
– ******* run all of your processing here *******
alter session set events ’10046 trace name context off’;
