Hello,
I got an issue related to lock.
Now the daabase was re-started and the issue is solved.
But during investigation I did not get sucess to identify who were locking
a table.
A table is used like this:
SELECT ID FROM TABLE_BLA
where id = :1
for upate;
The query did not return the result and looking for lock using this query :
select s.sid, s.blocking_session, do.object_name,
row_wait_obj#, row_wait_file#, row_wait_block#, row_wait_row#,
dbms_rowid.rowid_create ( 1, ROW_WAIT_OBJ#, ROW_WAIT_FILE#,
ROW_WAIT_BLOCK#, ROW_WAIT_ROW# )
from v$session s, dba_objects do
where s.ROW_WAIT_OBJ# = do.OBJECT_ID
I saw the row_wait_obj#, ROW_WAIT_FILE#, ROW_WAIT_BLOCK# and ROW_WAIT_ROW#
values.
In this situation how can I find the blocker?
or
I used a lot of queries that show blocker and locked but without sucess to
see the blocker.
Regards
Eriovaldo
