I gave 2 commands.

1) alter table xxxxxx.xxxxxx enable row movement;
table altered.

2) alter table xxxxx.xxxxx shrink space;

After the shrink space command, I dont see any error. The command is just hanging. I checked if its running in the background,its not. Please let me know why the shrink space command is hanging and how to resolve it?

DBMS_SYSTEM.SET_SQL_TRACE_IN_SESSION(sid,serial#,true);

do above or below

You could use realtime monitoring via

SELECT DBMS_SQLTUNE.REPORT_SQL_MONITOR('<sql_id>') FROM DUAL;

It would be helpful if you followed Posting Guidelines - http://www.orafaq.com/forum/t/88153/0/

Hi - you say

How did you do this check? The compaction phase of SHRINK SPACE can take a long time, are you sure it was not running?
