Not able to insert the same record after connection interruption

Question

I was inserting some records in the production table ,while doing that before commit ,I lost the production connection and none of the record got inserted.

Now when I am trying to insert the same record ,the sql plus is getting hanged and data is not getting saved.

But when I tried for other record which I was not inserted ,those records are getting inserted.

I have checked the table again ,for availability of data.Those previous data has not stored anywhere.

SQL plus is not generating any error also ,so that I can check the error and try to rectify.

Can anyone please help me to analyse and troubleshoot the problem.

while inserting in oracle the connection has lost now I am not able to add the same data

Answer 1

If your SQL/Plus session hangs, it's probably being blocked by your previous session. To find the offending session, you can use (requires DBA privileges):

select * from v$lock where block = 1

This should give you the session ID of the blocking session. Now you can run

select * from v$session

and check whether the session ID returned by the first query indeed belongs to your previous session. To kill the session, use the command

alter system kill session '<SID>,<serial#>'
