Actually after processed a PL/SQL statement with DBMS_DATAPUMP in a Java program, the dmp file and log were created. I want to count the rows in which the table was exported, so my solution is to read the log file right after processing the PL/SQL statement. My problem is that the log file was created but seems not flushed. I can't fine anything in it with a InputStreamReader. Does anyone know how to solve this problem? Thank you!!
