TG is developed using Java. therefore TG can run on any platform. TG emulates multiple user transaction environments using the Java THREAD function. TG generates random transactions which are constructed by SQL statements and enables you to send queries on the database, as well as calculating the TPS (Transaction Per Second). TG executes Job(SQL, PL/SQL, Shell script) on command. You can choose the command-line and GUI interface to control TG. TG can generate bigger transactions with multiple synchronized TG servers.
