PL/SQL Wrap

Are you planning to add a feature to Wrap packages and compile them directly into the database from SQL Developer (Raptor)?
thanks
Al

We did not plan on it however I'm going to write up a short howto on adding custom context menu items to the right click. So with this you could have a right click on a procedure to wrap yoru code for you. I'll try and get this written up today and use the wrapping as the example.

PL/SQL Wrap files

Hi All,
Just like to know What are PL/SQL wrap files and what is the use of these files ?
Thanks

We cannot read the source of wrapped PL/SQL files. This protects your code from prying eyes, something you might wish to do for either security or commercial reasons. The important thing about wrapping is that it is one way. There is no mechanism from reconstructing the source in plain text from a wrapped procedure.
Cheers, APC

There is nothing wrong with the code. I have created a package body and some procedures inside of it. Can anyone help?

I think the problem is that you are trying to compare a date value to a string in your PL/SQL, try something like this:
if to_char(:P_Year,'YYYY') !='2004'

DBMS_JOB (proc_1/sec) versus pl/sql wrap that calls proc_1 in a loop

Hello,
What implementation will have a better performance, in terms of using oracle resources(connections)?
I have Implementation # 1 deployed to an Oracle 10g database.
The DBA has complained that Implementation # 1 consumes too many resources to get a connection and Implementation # 2 is better because there will be one connection every 5 minutes.
Thanks.
Implementation # 1

job_no,
'BEGIN PKG_JL.RUN(300,1,'proc_1'); END;',

The business behind this 1 second job is an external process (a box passing by a bar code reader generates an event that is inserted in an event table TMSEVENTS). So this process only inserts rows into a table? When and how does it commit that insert? Does it do any other database activity/transactions?
The event generated by the external process will be processed by a PL/SQL procedure in my database and may take longer than one second.Why does this PL/SQL procedure only need to process a single row at a time? Why cannot it pick up a number of rows to process and process these in a fast and tight processing loop?
What the DBA has complained is the number of connections/unit of time created by the oracle job. He suggested that instead of 300 connections in 5 minutes (generated by DBMS_JOB) to use a new dbms_job that will execute every 5 minutes and call the same SP in a loop for 300 times with a sleep period of 1 second.
So my question is what implementation is better for oracle? 1 sec job or 5 min job?Neither. If I understand your process flow correctly, there is an external process throwing data into the database. This data needs to be processed as close to real-time as possible.
I would use Advance Queue feature of Oracle. I would want background server processes that listen on a queue for data process requests, dequeue the request, and process the request. This then provides a pool of processes that can dequeue and process requests - in parallel.
The external process now needs to enqueue processing requests - where that request will be dequeued and processed by this pool of processes.
This provides a scalable architecture. More external processes can be used to submit (enqueue) data processing requests. More dequeue processes can be created to allow for more requests to be processed in parallel. This also supports RAC - allowing you to scale horizontally (more db servers) and not just vertically (increase the size/capacity of the single db server).
You can roll this yourself, without using AQ. The issue is serialisation of the server worker processes looking at whatever object (e.g. table) for work to do (new rows inserted and not yet processed). You will need to find a way where there's minimal serialisation when multiple workers look for new rows to process, and process the oldest rows first. Not an impossible task, but a complex one - that using AQ eliminates as it handles that complexity for you.
And if I'm not mistaken, AQ is also available on XE. Which means this type of processing architecture you can use on XE and scale all the way up to the Enterprise and RAC editions of Oracle.

PL/SQL Wrap utility

Is there any information available on oracle's site about security with the wrap utility provided by oracle.
Can it be un-wrapped, can I get some pointers to it withing the oracle site.

Ten seconds work with "Search" on the 9i documentation pages gives this:
http://otn.oracle.com/docs/products/oracle9i/doc_library/release2/appdev.920/a96624/c_wrap.htm#138
You can't "unwrap" previously wrapped code, as that would defeat the point of wrapping it in the first place.

PL/SQL Wrap Utilityhttp://download-west.oracle.com/docs/cd/B10501_01/appdev.920/a96624/c_wrap.htm#LNPLS016
Note, however that you cannot revert back to original un-wrapped code from a code that has been wrapped. You would need access to the original source files to get the original source code.

Not able to compile wrapped package bodies.

Hi All
Can anybody pls help me finding me the reason why I m not able to compile .plb (wrapped package body). There are no compilation errors. But when I run the .plb file (as @xyz.plb), sqlplus window hangs. No error shown. Everytime I had to close the window after waiting for 8-10 minutes.
This is happening only with 11 files out of 200.Rest were compiled.
Any ideas? Do we have any other way to wrap than using pl/sql wrap utility or pl/sql plug-in for wrapping(which is actually the same as former)??
ThanksInAdvance!!
Keep striking the iron until it's hot!

yes, I did check for locks from pl/sql developer only. No Locks.
I waited for 10 minutes for a 6 kb .plb file to get compiled. But had to close the session after that.
I am using oracle 10g, pl/sql developer 7.1.0.1337

Unwrap Pl/sql stored procedure

Hi,
I have a pl/sql wrapped stored procedure which needs to be unwrapped. I know its kind of difficult. Has anybody ever tried doing it or achieved some positive results. Please let me know. I dont have the source code with me and hence the situation. thanks...

I dont have the source code with me and hence the situation...Unfortunately , your code cannot be modified.....You cannot unwrap your code.
That's why Oracle insists on keeping a copy of the wrapped routine in a readable text format....

Wrap utility security strength

Hello,
I am using the PL/SQL wrap utility to protect my source codes
that contains an encryption key. But my client wants to know
what is the security strength of the wrap utility. Anyone has
that information?
Thanks a lot,

How to make one map dependent on another ?

Assume you have 2 maps - M1 and M2
How to execute M2 automatically after successful run of M1 ?
or if I have process flows PF2 start after success of PF1 without a manual intervention
I looked at scheduling,.You can only set timing there but don't know how long your map runs.
Thank You

To make map dependant of another map you can use process flow. In process flow you can call M2 only if M1 is success. If M1 is failure you may exit the process flow.
Am not sure how it will work for process flow. May be writing a 3rd process flow and call PF1 & PF2 within it based on success status? or write some PL-Sql wraper procedure for the same???!!! give it a try.

Calendar Display Column Content Ordering

I would like to order the items returned to be displayed for a day by their values or a different column? The executing SQL wraps my source and adds an order by for the date. I don't see a way to modify that in 3.1.
e.g.
select date, name, name_sort from table order by date, name_sort
becomes
select * from (select date, name, name_sort from table order by date, name_sort) where <date range test> order by date
I can have 0 to 88 different names for any given date. I want to display the name, but order the names by the name_sort column.
Thanks,
Ed

Ed,
Your query for the calendar could look like this
SELECT ename, hiredate + rownum / 24 / 60
FROM (SELECT   ename, hiredate
        FROM emp
       ORDER BY ename)which will sort the values in ascending order.
SELECT ename, hiredate + 1 / rownum / 24 / 60
FROM (SELECT   ename, hiredate
        FROM emp
       ORDER BY ename)See this example:

Uploading a csv file through XDB FTP

Hello
I'm developing a project where i need to upload a big amount of data, contained in a CSV file, on the file system of a database server and it would be great if the FTP service provided with XDB could be used to achieve such a job.
Does somebody know if XDB-FTP is able to upload files outside the XML repository and to upload them directly ( without intermediate steps that may generate heavy redo-log generation ) into a file-system on the database server?
I'd like to consider other good alternatives too, now I'm using a different FTP server but I would like to avoid this dependency.
Thanks

Encryption in oracle

i create a program in my database and
i want that no one see it source code
even DBA and my BOSS
how i can do this
kuljeet pal singh

You can use the PL/SQL wrap utility to encrypt source code http://download-west.oracle.com/docs/cd/B10501_01/appdev.920/a96624/c_wrap.htm#LNPLS016. Make sure that you keep the actual PL/SQL source in some sort of version control system if you do this-- otherwise no one (not even you) will be able to get the original source code back.
I would be curious, though, why you would want to prevent people like your boss from seeing your source code. I can understand not wanting customers who are being shipped applications to see the source, but I'm hard pressed to come up with a situation where I would have an ethical reason to prevent my boss from seeing the source.

Hi all..

{code}

Assuming that PL/SQL Developer doesn't display Java stored procedures...
The Java source is not stored in the file system. It is stored somewhere in the data dictionary. I couldn't tell you how to extract the source from the data dictionary, though. It's not as simple as grabbing the source from DBA_SOURCE. You might ask over in the Java Stored Procedure forum. The folks over there may be more familiar with the Java stored procedure data dictionary views.
Personally, I'd tend to just grab SQL Developer and/or grab the source from your source control system.
