Oracle中查看当前执行的sql或PL/SQL

来自TOM的showsql.sql
It shows everyone logged in and if they are active, what they are doing and how long they've been doing it. If someone is executing PLSQL, what you will see will depend on what the plsql is currently doing. If the plsql is doing SQL, you'll see the SQL. if the plsql is doing lots of PLSQL work -- you'll see that code. What I like to do is have everyone "instrument" their code with calls to dbms_application_info which can fill in the client_info, action, and module columns in v$session. In this fashion, you can see where in a procedure someone is based on the values in these columns. showsql exposes this information to you as well. sqlplus uses it to show you what script someone is running for example... ---------------- showsql.sql --------------------------
