Hi all

Restricted rowid listed by Eterprise manager was 221682.13.9

Ok solved the problem to get from restricted rowed as listed for blocking locks to actual row involved in problem.

To get the extended rowid:

select dbms_rowid.rowid_to_extended('221682.13.9','COR','CUSTOMERS',1) FROM DUAL;=20 Or for the same value

select dbms_rowid.rowid_create(1, 8172, 9, 221682, 13) from dual; with 8172 determined before hand.

And now to get the actual row in the table involved use the above query in line:

select * from customers where rowid=3D(extended rowid =3D select dbms_rowid.rowid_create(1,8172,9,221682,13) from dual);

thanks for the help guys.

George

it is the rowid on which the waiting session is we... waiting. That can be seen in v$session, the columns to use are

row_wait_obj# -> the object

row_wait_file#  -> datafile number
row_wait_block# - > block#
row_wait_row# -> row within the block.

then use dbms_rowid package to construct the actual rowid.
