Scope of local modules

Many articles concerning PL/SQL best practices promote the use of local modules for code clarity. I am wondering how this affects testability due to limited scope (we use utplsql.)
For example, if I write
PROCEDURE A
IS
PROCEDURE B...
PROCEDURE C...
BEGIN
// procedure A body
END A;
is there any way that I can expose or fully qualify B or C for testing, without moving them outside of A ?? As far as I can tell, the answer is no, but I'm wondering if someone out there knows a trick that I have overlooked.
Thanks for the help,
Mark

Hello
Well, I'm probably going to get slated for saying this but [opinion]I think the idea that local modules somehow improve code clarity is highly misguided. There are cases (very few I have come across) where they can be of use but in the long term I think they can easily lead to very poorly structured code and make it very easy for subsequent developers to take nasty little short cuts. I accept that virtually all program constructs can be abused, but I have found that local modules bring out some of the worst coding "practices" I have ever seen, and I am yet to see any benefit other than for anonymous pl/sql blocks, and very simple helper routines such as string formatters or expression generators.
Like all tools, they should be used when necessary, when they fit the problem at hand, and not applied as an over-all "best practice". I tend to be very sceptical of any one size fit's all approaches to development so maybe I'm slightly prejudiced.
The issue you have raised, to me at least, is one reason why you would not use local procs. If they are complex enough to require testing that requires them to be called in isolation, I think they should probably be separate.

"Local Module is not an executable or is a link" when starting Messaging Server

If you see error messages like this one when you try to start Netscape
Messaging Server:
19971009095543:Dispatch:Notification:Local Module (Account-Handler) is
not an executable or is a link.
Module not loaded.
Startup Problem:
Module Error-Handler is required for proper operation.
Netscape Messaging Server Exiting!
You may have a file permissions problem. This can happen if you change
the Unix account that Messaging Server runs as. Try changing the
permissions on the "bin" directory in your Netscape server root to make
sure that the current Messaging Server user account has access to it
(try granting public read and execute permissions to that directory);
this should solve the problem.

Amazing how you can do something as difficult as mod a game not yet built to be modded and yet not even know the basics of the basics of the command prompt, nor have the capacity to research it apparently.

Local Module (Error-Handler) Failed the verify environment test

When attempting to start the Messaging Server, the following error
message occurs and the server fails to start:

19980226114147:Dispatch:Notification:Local Module (Error-Handler) Failed
the verify environment test.
 Module not Loaded.
 Startup Problem:
 Module Error-Handler is required for proper operation.
 Netscape Messaging Server Exiting!

This problem can be caused by a corruption to the configuration file
for the admin server that controls the Messaging server
(install_dir/admin-serv/ns-admin.conf).
Specifically, if the
Port setting is missing, the above-mentioned error will occur.

Add a valid Port setting to the
ns-admin.conf file and
rerun the /etc/NscpMail start command.

Is anyone having any idea about it...

Scope order: local vs argument

Hi,
According to http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec09af4 -7fdf.html, LOCAL variables take precedence to ARGUMENTS variables. However, when I access an unscoped variable in a CFC function that is available in both LOCAL and ARGUMENTS, I get back the ARGUMENTS scope. Why is that? I am using CF 9,0,0,251028.
<cfcomponent>
 <cffunction name="testFunction" access="public" returntype="string">
 <cfargument name="x" default="argument">
 <cfset LOCAL.x = "local">
 <cfreturn x />
 </cffunction>
</cfcomponent>
<cfset obj = createObject( "component", "component.Test" )>
<cfoutput>#obj.testFunction("argument")#</cfoutput>
The output I get back is "argument" instead of "local".
The other thing that I find weird is that if I replace
<cfset LOCAL.x = "local">
with
<cfset var x = "var">
I get the error message "X is already defined in argument scope".

Hmm, I have never heard of the "local" scope. Are you sure the doc is not referring to <cfset var x = "local" /> as being a local variable? Try changing your example to the following:
 <cffunction name="testFunction" access="public" returntype="string">
 <cfargument name="x" default="argument" />
 <cfset var x = "local" />
 <cfreturn x />
 </cffunction>

Cannot find scope's local variable

I am doing the soa tutorial. In the step of 5.11.5 Task 5: Reference the RequriesApprovalRule Dictionary in the BPEL Designer, I cannot find the variable of IorderApproved when I add "assign output facts" in the business rule activity.
A local variable named "lOrderApproved" was defined in the scope Scope_CheckApprovalLimit. According to the tutorial, I create the business rule and refered it in BPEL.
However, in the step of Assign Input Facts, I cannot see the lOrderApproved under the Scope_CheckApprovalLimit.

There are lot of sequence of steps in this tutorial. If you miss something you cannot proceed further. I would redo from first step.

Dear All,
My Client is implementing all the following modules: OM; PA; Time; Payroll; Comepnsation Mgmt.; Training & Event Mgmt; Personnel Development; Recruitment.
Now they want to go for ESS & MSS also. I have rough idea of ESS & MSS functionalities but not aware what all functionalities it give with respect to these modules.
I need to give the scope/efforts along with the timelines.
Kindly help me in understanding the functionalities of ESS/MSS related to above mentioned modules.
If you have any document, kindly share.

Scope of Func module???

Hi guys
Customer using Func group ZXXXXX, and using BDCRECXY include inside funcgroup
to access for Func modules.
In func module Z_XXXX_PLAN, PERFORM BDC_TRANSACTION statement is
called and "Call transaction CJ30" is used under Subroutine "BDC_TRANSACTION"
inside the BDCRECXY
How to make sure that This Func module is calling include BDCRECXY using BDC_TRANSACTION Subroutine.
In the where used list for BDCRECXY program,it listed only 2 other programs(Func module) LZPS00010U14 and LF040TOP.
How to make believe that BDC_TRANSACTION is calling BDCRECXY include?

Inter module call ( no ear )

I have an appli say A containing EJB A, and a standalone module say MB containing EJB B.
MB is deployed standalone ( not in an ear).
I do not succeed to call EJB B from EJB A.
there is an ejb-ref in the module of A with an ejb-link to ejb B but when I deploy I get : Error: Unresolved : Test9
I alse have tried this syntax :
<ejb-link>moduleName#Test9<ejb-link>
I also get an error saying it could not find the module.
Any idea ?
thanks
Michel

I suppose you're trying to access the EJB's using "Local Interfaces". If this is the case your problem is due to the scope of every module, I mean MA can only see the LocalInterfaces of its EJB container, so it won't see any Local Interfaces from MB.
If you put this two modules in a single EAR you can use local references from MA to MB adding the MB jar file to the classpath of MA (using the "manifest" archive of the jar file).
I hope this helps you.

ModuleData.getPrincipalData returns null in the adapter module development

Hi gurus,
i am doing a test on the adapter module development following an article written by William Li:
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/f0ac06cf-6ee2-2c10-df98-e17430ca5949?QuickLink=index&overridelayout=true
my problem is after the EJB has been deployed, it seems that the return of inputModuleData.getPrincipalData() is always null which makes the program can not get the xml payload from the framework.
the main process of the example has been simplified like this:
     public ModuleData process(ModuleContext moduleContext, ModuleData inputModuleData) throws ModuleException {
          Object           obj = null;
          try {
          obj = inputModuleData.getPrincipalData();
          Message     msg1 = (Message) obj;
                XMLPayload xmlpayload = msg1.getDocument();}
          catch (Exception e) {
               ModuleException me = new ModuleException(e);
               throw me;
          return inputModuleData;
after deployed, i get the following error in the adapter monitor of RWB: (my JNDI is testtest)
17.02.2012 17:13:44.643 Information Send binary file "test8.xml" from FTP server "10.18.48.150:/encrypt_test/", size 206 bytes with QoS EO

whereas if the code has been changed like this:
     public ModuleData process(ModuleContext moduleContext, ModuleData inputModuleData) throws ModuleException {
          Object           obj = null;
          try {
               obj = inputModuleData.getPrincipalData();
               Message     msg1 = (Message) obj;
               if (obj != null )
                    XMLPayload xmlpayload = msg1.getDocument();
          catch (Exception e) {
               ModuleException me = new ModuleException(e);
               throw me;
          return inputModuleData;
the file can be read by the file adapter.
i just quite confused that why the return of the getPrincipalData() is null? where is the problem? thanks
Edited by: Stephen Xue on Feb 17, 2012 5:22 AM

I'm gonna reply to myself here. I changed the processing sequence of the adapter modules in the in the FileSender channel so that my module comes first then CallSapAdapter. Then getPrincipalData() contains the message.
Hope this helps someone else.

Hi All,
Issue has been resolved. There was some minor issue in the XSL. The XSL Stylus studio was not reporting this as an error. However PI's XSL engine was reporting that error. This error message was not showing up in runtime workbench. However, when i looked at the default trace, there were few more errors. After fixing the XSL, I am able to received the email

Mayank,
Using Request Response bean had some problems when used in PI 7.1, I don't whether it is still in Ehp1 as well but we could use the RequestResponse bean by implementing OSS note 1261159.

Local procedures: in the documentation [FOUND!]

Within a procedure or function, you can declare local procs/functions. These have to be declared after all the other variables, cursors, etc.
However, I'm struggling to find where it states this in the oracle documentation (although I found a comment in Steve Feuerstein's Oracle PL/SQL Programming)! Can anyone with better oracle-documentation-fu than me find it - or confirm that it's not there?
(This came about because one of my colleagues raised an issue with declaring a local procedure before the variable declarations, and I wanted to point them to a link in the docs which tells them about where they should declare it.)

heh, no didn't think of subprograms either. Subprocedures Sub procedure (did you know there's a procedure called Sub?!), sub module, local procedure, local module... etc
My oracle-documentation-fu severely lacking today! Thankfully, its working for others *{:-D

Hello Hery,
Generally, supervisor probe all the linecard by using hearbeat messages. Due to some reason supervisor did not hear any keepalive reply from any linecard then supervisor reset that linecard to recovery .
2014 Nov 21 11:47:39 WIB MASTER %MODULE-2-MOD_NOT_ALIVE: Module 3 not responding... resetting (Serial number: JAF1612ASPA)
From the above log, it looks like same thing happened in your case also . This is due to multiple reason , But most of the time EOBC congestion, EOBC drop or bad fabric connection . This could be either hardware issue or transit issue.
you can set diag level complete and reset the linecard once . After reseat (physical reseat- means remove the Linecard and insert it back) if you see any diagnostic failure or crash again then you need to replace the card otherwise its transit issue .

Flex 4 Modules and Stylesheets

I am having trouble using stylesheets in a module, in particular with class styles (i.e. ".myStyle"). They are not loading at compile time. My module is:
<?xml version="1.0" encoding="utf-8"?>
<mx:Module xmlns:fx="http://ns.adobe.com/mxml/2009"
 xmlns:s="library://ns.adobe.com/flex/spark"
 xmlns:mx="library://ns.adobe.com/flex/mx"
 xmlns:views="com.fosrias.portal.views.*"
 xmlns:maps="com.fosrias.portal.maps.control.*"
 layout="absolute">
 <fx:Style source="../assets/styles/main.css"/>
 <views:PortalUI left="0" top="0" right="0" bottom="0"/>
</mx:Module>
Any my main.css contains
mx|SomeComponent {
 etc.
.myStyle {
 etc.
The type style mx|Component loads, but the class style .myStyle does not. Should this work, or do I have to compile my styles to a swf and load them a runtime? Thanks

So, the component's (which is a UIComponent subclass in the module) styleManager.ModuleFactory is the top-level application (ii.e. app embedding the module) system manager. Not, the local modul's systemManager.
Chokes, means returns null on the getStyleDeclaration call.
However, per the documentation here :
http://help.adobe.com/en_US/flex/using/WS2db454920e96a9e51e63e3d11c0bf69084-799a.html
Using styles with modules
When you set styles on modules, the style properties are set on the local StyleManager. Each module has its own instance of the IStyleManager2 class. This means that each module can load its own set of styles, and its styles do not necessarily affect the styles of other modules.
After an application finishes loading a module, the module’s styles are merged with the styles of the application. The module’s StyleManager walks the chain of parent modules and applications, up to the top-level StyleManager, and merges its styles with those set on the StyleManagers above it.
Thus, it seems the styles should merge and thus be accessible by the top-level system manager, no?
That being said, if not, how do you actually locate the the local system manager instance to use it? Or can't you?
Thanks.
