DEV410: Inside the ASP.NET Runtime

Some code shows how to manage transaction in multiple database system


we create a table test_log in remote database, and a procedure test_log_pkg.insert_log to insert log into this table

create or replace package body test_log_pkg is
procedure insert_log(pvs_log in varchar2) is
begin
insert into test_log values (pvs_log);
end;
end test_log_pkg;


we create a procedure test_dblink_pkg.insert_remote_log in local database which invoke the insert_log in remote database by database link. we added PRAGMA AUTONOMOUS_TRANSACTION in declaration section, and commit the insert at the end.

create or replace package body test_dblink_pkg is

procedure insert_remote_log(pvs_log IN varchar2) is
PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
insert_log@remote_db(pvs_log);
commit;
END;

end test_link_pkg;

then we create a table test_log in local database, and we create a test procedure which insert log into test_log in local database, and
invoke insert_remote_log to insert log into test_log in remote database, at the end, we rollback all of operations.

procedure test(pvs_log IN varchar2) is
BEGIN
insert into test_log values(pvs_log);
insert_remote_log(pvs_log);
rollback;
END;

after we run test, test_log in remote database has a new record, but test_log in local database has nothing.
It shows that the transaction for local database is rolled back, but the transaction for remote database is commited

ObjectSpaces and Whidbey

ObjectSpace will be come later than Whidbey, the reason seems like that ObjectSpace use some new feature in WinFS, such as a new Query syntax(hybrid-SQL-and-XPath),
is that means ObjectSpace only for Sql Server because WinFS use Sql server

Essential Delphi 8 for .NET

There are a preview chapter available for downloading.
Something I got from this charper,
1. Initialization in D.net become the Static Class Method and called from Class Constructors
2. sets in D.net become the enumeration class (marked as sealed) that inherits from System.Enum.
3. the difference between record with methods and class in D.net is the way the use memory, the record is in stack and the class is in heap, so the record is a little bit more efficient.
4. StringBuilder is for increasing the performance of string concatenation. it is much faster than common string concatenation.
5. the Direct type cast became more restrictive in D.net. Integer (anObject) is no longer allowed
6. protected symbols defined in another unit are accessible only within the same assembly/package, but not across package boundary
7. ECO framework use Class Helper too, the Class Helper in D.net looks like the partial class in c#
8. published property in D.net become the BrowsableAttribute in CLR
9. Any class needing resource clean-up should implement the Dispose method of the IDisposable interface,
and add the 'using' clause in c#. the VM will free the object and resource in the the score of 'using' clause, this way eliminate the delay of GC.
in D.net, the Destroy() method becomes an implementation to Dispose. nice
10. However the Delphi 8 compiler cannot impose the presence of a specific metaclass for classes not
compiled by Delphi but imported from assemblies written in other languages.
