Answer / sudhir
by default Trigger doesnt allow a commit;
however we can create a stored procedure which will only do
commit.
create or replace procedure to_commit_trigger
begin
commit();
end to_commit_trigger
now execute this stored procedure to_commit_trigger inside a
trigger to perform a commit. However it will cause serious
performance issues.
