Here, the example code that contain dynamic sql to query specific data from table x in database link name y:

ds_numrows NUMBER; --as global variable
ds_cursor_id NUMBER; --as global variable
queryString := 'SELECT x.attr1, x.attr2 from x@y';
ds_cursor_id := DBMS_SQL.open_cursor;
DBMS_SQL.parse (ds_cursor_id, queryString, DBMS_SQL.v7);
DBMS_SQL.define_column (ds_cursor_id, 1, queryString, 1024);
ds_numrows := DBMS_SQL.EXECUTE (ds_cursor_id);
LOOP
IF DBMS_SQL.fetch_rows (ds_cursor_id) = 0
THEN
EXIT;
END IF;
DBMS_SQL.column_value (ds_cursor_id, 1, queryString );
END LOOP;
DBMS_SQL.close_cursor (ds_cursor_id);
COMMIT;


First step, I should install Oracle 8i in Windows XP before create the dblink. So many times I tried but the 8i setup was still not working. Then, as usual, I’m googling and.. tam.. ra.. ram…
just do this:

1. Copy the content of your Oracle CD into hard disk in your machine. For example Copy from oracle8i CD into D:\Oracle\ …
2. Search the file Symcjit.dll on the D drive (where you have copied Oracle8i. You can found it in:
   • For Oracle8i 1.7:

   D:\Oracle\stage\Components\oracle.swd.jre\1.1.7.30\1\
   DataFiles\Expanded\jre\win32\bin\symcjit.dll

   • For Oracle8i 1.6:

   D:\Oracle\stage\Components\oracle.swd.jre\1.1.7.24\1\
   DataFiles\Expanded\jre\win32\bin\symcjit.dll

3. Rename those file (Example): symcjit_back.dll
4. Execute the Oracle setup.exe from D:\Oracle\setup.exe

Yatta, it’s really works Friend..
Ok, lets go to the next step.. ^o^

To write your own PHP code to send email using SMTP-auth, there are PHP PEAR Mail package available for usage (which supports smtp-auth). PHP code sample below shows how to use this feature to send an email:


require_once "Mail.php";

/**************************************************
EDIT the following variables for your own use
***************************************************/
$from = "user@domain";
$to = "user2@domain2";

$subject = "Hi!"; //type in subject here

$host = "host_ip"; // Your domain
$username = "user"; // Your user / full email address
$password = "password"; // Password to your email address

?>


grabbed from here


conn1 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = IP_Address)(PORT = 1521))
)
(CONNECT_DATA =
(SID = XE)
or (SERVICE_NAME = conn1)
)
)


then save the file and open the command prompt (windows key + R, type cmd).

Export:

To export, type this command in cmd:
>> exp user/password@instant
It will show many questions, leave it with default answer using hit enter. But, there are the important question, such as:
- (2)U(sers), or (3)T(ables): (2)U >
2 : to export all database under user that mentioned above
3 : to export selected tables only. If 3 choosed, it will appear question what tables that will be exported
- Export grants (yes/no): yes > (type Y or N)
- Export table data (yes/no): yes > (type Y or N)
- Compress extents (yes/no): yes > (type Y or N)

In the rest, make sure that appear message Export terminated successfully without warnings.

Import:

To import full dmp file type this command in cmd:
>> imp user/password@instant file=emp.dmp log=imp.log full=yes

To import dept table alone type this command in cmd:
>> imp user/password@instant file=emp.dmp log=imp.log fromuser=user touser=user tables=dept

FROMUSER and TOUSER clause are optional. But in case if used, then create a user in the destination database that is mentioned in TOUSER clause then try importing the dmp file.

In the rest, make sure that appear message Export terminated successfully without warnings.
If there are still warnings, please check the dblink connection. If it has a problem connection with dblink, drop the current dblink (result of importing) and create new dblink with simple new name.

This LOCK file still there, because the IS machine stopped incorrectly. While system stopped, the LOCK file hadn’t deleted.

OK, this is the start. I’m still learning too..
