Using MapViewer from PL/SQL vs Java

Hi group!
The MapViewer User's Guide has this to say about using MapViewer from PL/SQL:
"The usage model for the SDO_MVCLIENT package is almost identical to that of
MapViewer JavaBean-based API" etc etc .. "For usage and reference information about specific functions or procedures, see the description of the associated JavaBean-Based API. methods and interfaces in Chapter 4"
If I don't misunderstand the basic concept, in a Java Web App (using the MapViewer Bean) you create a MapViewer object for each HTTP-user-session, like so:
MapViewer mv = new MapViewer("http://my_corp.com:8888/mapviewer/omserver");
... which you would then store in the user's session object, so that the MapViewer Bean conveniently holds the map's state on the user's behalf.
To do the equivalent in PL/SQL, the User's Guide suggests:
"connect scott/tiger
call sdo_mvclient.createmapviewerclient(
'http://www.mycorp.com:8888/mapviewer/omserver') ;
The preceding example creates, in the current session, a unique MapViewer client
handle to the MapViewer service URL"
Does "current session" refer to the HTTP-user-session? While I've used PL/SQL before, I've not used the PL/SQL Web Toolkit. Is the session handling implicit here (and invisible?) or should the sdo_mvclient be subsequently stored in the PL/SQL equivalent of a (J2EE) HttpSession object?

Part of the answer will depend on how you plan to deploy the application. If you have a few, local clients you could go with the traditional client/server model. If you have a lot of clients and/or they are spread out over a relatively large area (like a campus setting), a web front-end will save you a lot of hassels down the road when it comes time to upgrade.
Regardless of the the front end, I can tell you that I have been greatly impressed with the throughput you can get by moving most of the code to PL/SQL packages. A few years ago we reworked a VB/Oracle app by moving a lot of the code out of VB and into packages, leaving the client to essentially call procedures and format the output. We had more than a 3x performance increase on the same hardware and our network utilization decreased noticably.
I am now in the process of replacing the client code with Java servlets/JSP, primarily because of the maintenance hassles I mentioned earlier. There are some limitations with an HTML page but most of these have been cosmetic so far.
We are still relying heavily on PL/SQL packages. The servlet code basically gets a request, calls a package to get the data, then hands the results to a JSP page. The JSP then formats the output and sends it to the client. We are little more than halfway through the re-write, but it appears performance will increase again. Not as noticably as before, but I will take what I can get. As you have seen, once something is rolled out it always ends up getting used more than you anticipated. Better to over-engineer now than have to patch it once it is live.

Call DLL from pl/sql

Hi Every one
I have to call one microssoft dll from the pl/sql using form .
How can I do it.
Prashant

That likely means that the DLL call failed.
Some basics.
A DLL exposes an interface where it lists the names of the proc/func exposed (together with a number/ordinal for each).
The Win32 LoadLibrary() call is used to load a DLL. This returns a handle that is then used by subsequent calls to the DLL.
In order to make the actual call, the caller needs to know the address of the procedure/function in the DLL. The GetProcAddress() is the Win32 call I remember using to get the address to call (but I think it has been deprecated since).
Anyway, for the caller to call that proc/func in the DLL, it needs these steps:
- load that library
- get the "address" of that proc/func in the DLL
- make the call
The DLL is then executed - in the address space of the caller. Yes, the DLL's code segment is loaded once and shared amongst how ever many executables are using that DLL. But the DLL has no data segment - the data segment of the DLL lives in the address space of the caller.
Should the DLL do something dirty/wrong, it can crash the caller by corrupting its address space. Or the DLL call could simply fail, throw an exception and terminate unexpectedly.
This is the basics of the a DLL call - and also why Oracle wants to run that DLL call externally using the EXTPROC interface, so as not to risk that DLL compromising the memory space of the Oracle server process.
This makes it a tad more complex now as the Oracle server process makes a call to EXTPROC (an IPC/RPC call) - and the EXTPROC process makes the DLL call (as described above).
If that EXTPROC process crashes, the call that the Oracle server process made also terminates unexpectedly.
Why can the EXTPROC process crash? Well, there are more meaningful errors returned when the DLL fails to load in my experience. So I expect that your DLL was found and that the EXTPROC process did a successful LoadLibrary() call - and even made a successful GetProcAdress() (or whatever call).
But when the actual call to the DLL func/proc was made, an error resulted (incorrect parameter passing, invalid data types being passed, invalid memory being referenced, etc).
This error caused a fatal error and terminated the EXTPROC process. No meaningful error was therefore returned to the Oracle server process - so it throws the exception "lost RPC connection to external process".
Hope this was not too technical and you got the gist of it.

How to determine from PL/SQL which processes are running

Hi,
I would like to find out which processes are runing. Is there any way how to determine this directly from PL/SQL? I know I can run external C libraries, but if there is another way, that would be great.
Thanks for help, Dan

HOW TO LOGIN FROM PL/SQL?

I want to test some application logic that uses
wwctx_api.get_user and other session related information. Instead
of logging in from the web, I want to login from PL/SQL and
test the rest of my logic. How do I do that? I tried using
PORTAL30_SSO.wwsso_app_admin.ls_login. But it raised exceptions
since SYS.OWA_UTIL is failing.

You can use WWCTX_API.SET_CONTEXT - this is documented in the
PLSQL PDK.

How to integrate from MS SQL SERVER 2005 and Flatfile to Oracle 10g.

Hi
I am new to ODI. I am trying to load sample data from MS SQL Server 2005 and Flatfile to Oracle 10g.
1. I have created three models.
1-1. SQL2005 (SRC_CUSTOMER table)
1-2. Flatfile (SRC_AGE_GROUP.txt & SRC_SALES_PERSON.txt)
1-3. Oracle 10g (TRG_CUSTOMER table)
You may know I got those environments from the ODI DEMO environment.
2. I could able to reverse the tables also.
3. I have created an interface which contains source table (from MSSQL 2005), Flatfile and target table from ORACLE model.
4. I have imported the knowledge modules. But I am confusing in selecting the knowledge modules to source and target tables.
I've selected LKM File to SQL for flatfile model.
I've also selected LKM SQL to SQL for MSSQL 2005 model and IKM Oracle Incremental Update for the target table (ORACLE).
I've also implemented the interface that I created. It worked without errors. But there is no data in target table which is TRG_CUSTOMER.
I really would like to know what happened and what the problems are.
You can email me [email protected]
Thanks in advance
Jason Lee

what did give for SRC_AGE_GROUP SRC_CUSTOMER join condition
if it is
(SRC_CUSTOMER.AGE=SRC_AGE_GROUP.AGE_MIN) AND SRC_CUSTOMER.AGE=SRC_AGE_GROUP.AGE_MAX
give it as
(SRC_CUSTOMER.AGE>SRC_AGE_GROUP.AGE_MIN) AND SRC_CUSTOMER.AGE<SRC_AGE_GROUP.AGE_MAX

Call Micrsosoft DLL from pl/sql

Hi
i have one dll microsoft VB. which returns some control chars.I have to call it from my PL/SQL code.How can I do it.Please help
Prashant

You must build an external library, declare it as a LIBRARY object inside Oracle, configure your lib paths, and configure your listener.
Once you've met the config procedures, next you have to create a wrap function to access your external funcion inside a PLSQL block.
Check this documents:
http://download-west.oracle.com/docs/cd/B19306_01/appdev.102/b14289/dcimethcj.htm#sthref250
http://download-west.oracle.com/docs/cd/B19306_01/server.102/b15658/ldr_demo.htm#sthref565
http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14231/manproc.htm#ADMIN00501
Step 1 - Make entry in the TNSNAMES.ORA.
======
Make the following entry in the TNSNAMES.ORA:
extproc_connection_data.world =
     (DESCRIPTION =
          (ADDRESS =
          (PROTOCOL = IPC)
          (KEY = extproc))
          (CONNECT_DATA =
               (SID = extproc)
Step 2 - Make the necessary entries in the LISTENER.ORA.
======
You can either add an entry to the existing listener or add another listener
process.
Option 1: Add an Entry to the Existing Listener
The information contained in each listener differs. Defining the
listener process is done in two parts. The first part is as follows:
LISTENER =
(ADDRESS_LIST =
(ADDRESS=
(PROTOCOL= IPC)
(KEY= V803)
(ADDRESS=          <-Add this line.
(PROTOCOL= IPC) <-Add this line.
(KEY= extproc)     <-Add this line.
(ADDRESS=
(PROTOCOL= TCP)
     (Host= ###.#.#.#)
(Port= ####)
Step 3 - Start the listener process.
======
Any modifications to the existing listener require that you stop and
restart the listener to reload the new listener configuration. Adding a
second listener process, instead of modifying the current, only requires
the startup of the new listener process.
Step 4 - Create a sample DLL using the following code.
======
The following is a basic example of an external procedure. It is a good
way to test to ensure that the environment (mainly the listener) is configured
correctly.
Note: For the remaining steps, the DLL name should be MYEXTPROC.DLL.
#include <stdio.h>
int __declspec(dllexport) square(int x)
return(x*x);
Step 5 - Move the DLL to same server where the database is located.
======
The DLL can be placed in any directory. One approach would be to create an
EXTPROC directory under the ORACLE_HOME and use this to house all external
procedures.
Step 6 - Create the required library.
=======
Log into SQL*Plus and create a library to be associated with the external
procedure.
Note: The user must have CREATE LIBRARY privileges.
CREATE LIBRARY <mylib> AS <path\filename>;
SQL> CREATE LIBRARY SQUARE_LIB AS 'D:\ORANT\EXTPROC\MYEXTPROC.DLL';
Step 7 - Register the external procedure.
======
An external procedure is not called directly. Instead, you call the PL/SQL
subprogram that registers the external procedure. This can either be a
Function or a Stored Procedure.
CREATE OR REPLACE FUNCTION <FunctionName> (<parm1>...) RETURN <value> AS
EXTERNAL LIBRARY <mylib>
NAME "<Name Of Function In DLL>"
LANGUAGE C;
CREATE OR REPLACE PROCEDURE <ProcedureName> (<parm1>...) AS
EXTERNAL LIBRARY <mylib>
NAME "<Name Of Function In DLL>"
LANGUAGE C;
CREATE OR REPLACE FUNCTION square_of (X BINARY_INTEGER)
RETURN BINARY_INTEGER AS
EXTERNAL LIBRARY SQUARE_LIB
NAME "square"
LANGUAGE C;
Step 8 - Run the external procedure.
======
Use the following code to execute the external procedure:
CREATE OR REPLACE PROCEDURE EXTPROCTEST (X BINARY_INTEGER) AS
RetValue BINARY_INTEGER;
BEGIN
RetValue := square_of(X);
DBMS_OUTPUT.PUT_LINE(RetValue);
End;
EXECUTE EXTPROCTEST(15);

Issue in using DLLs from a VC++ 6.0 MFC application

Hi Mukund!
I found this response on another forum thread that looked like it could help you out:
==============================================================
MSVC++ error (system error 998)
This is actually a Microsoft issue. It has something to do with static and
dynamic linking of the MFC DLL. Our R&D engineers have verified this with projects created with no LabVIEW code at all (that is why we believe it to be solely a Microsoft issue). There are three options at this time:
1. Link with the DLL form of MFC.
2. Do not link with the .lib from the LV DLL, instead use LoadLibrary and GetProcAddress to dynamically load the DLL and call the function.
3. Use the VC delayload feature to make the LV DLL not get loaded until the first call is made into it. See VC help on "delayload" for information on setting this up.
