You could try to find the accessing sessions by

select /*+ rule */ sid from  v$access where object='<YOUR TABLE NAME>' and owner='<YOUR OWNER>';

Forget about it and remove it from the query, it's just a comment for you.

i apply the fol on sql prompt after logging " / as sysdba"
select  sid from  v$access where object='schema12.table1' and owner='schema12';

but i got no result and the query is going and going. i do not get my sql prompt. i started this query since last 40 min uptill now still processing, why is this behavior of the query? it should get me the session ID but it stuck or it will take time?

kindly advice

Regards

Object names and owners are stored in upper case in the data dictionary by default so that needs to be:
select sid from  v$access where object='SCHEMA12.TABLE1' and owner='SCHEMA12';

And the schema name won't be in the object name, so actually:
select sid from  v$access where object='TABLE1' and owner='SCHEMA12';

It is generally problematic to select from v$access. The hint RULE helps to get the result relative quickly (at least in some cases).

I really didn't understand anything you said here. Did the table drop? I think someone is not going to be happy because you said it was not in use, yet something was using it, hence the ORA-00054 error.

yes, table doped but let me say it again that it was not used by our application but even then i was getting this error but now next day i came and try to drop it so they got dropped which i am surprise too and also querying the same strange behavior.

Note that we have some 10 stations where this activity has to perform and it was successfully completed but in station 7 i had this problem. so problem is solved but no learning take place for me and may be anyone else.

Hi jana,

While i was searching for the solution to the resource busy wait error, i found your topic to be interesting.
Thought of replying to the issue you faced.

I faced the same error while trying to drop a table.Actually what happened is i ran one table import and
due to client connectivity got disconnected ,import got terminated in the middle.So when i try to drop the same table from database i get error "resource busy bla bla ..

So what action i took is i found which session id is blocking me to drop the table using below query

select sid from  v$access where object='TBL_TEMP' and owner='JACK';


Then found the serial# for the SID using v$session view using

select sid,serial#,status,program from v$session where status='ACTIVE' and sid='21'


Then killed it using
ALTER SYSTEM KILL SESSION '21,2825';


If the above scenario doesn't work , wait for the lock to get release and then drop the table.

I hope the solution which i provided might help you in future.

All the best!!!
