Re: [U2] UniObject .NET Session and Common Block Bug
Maybe you could return something in SR.AHTEST.CALL1 and try to run
ahsub1.GetArg(1); before ahsub1.Dispose(); , so you can make sure the first
subroutine has been finished before you run the second one.

Hi All,
I am trying to call 2 subroutines using the same session in UniObject

I call the first subroutine without any issues. But when I call the

subroutine I get the following error.
[IBM U2][UODOTNET - UNICLIENT][ErrorCode=30105] Unable to load the

I only have this issue in .NET and not in VB6.
I believe that the .net UniSession is storing the Common Block variables
and when I try to call another subroutine with a different common block
it
fails to load.
I have read in another post on the web that people have created a Common
Block loading subroutine to load all Common Blocks when they create the
session.
This way when ever they call any subroutine they know the common block
does not increase.
This seems a like a hack to me.
I am worried that when ever a developer creates a new Common Block that
they have to remember to update the Common Block loading Subroutine.
Also we have thousands of Subroutines that may or may not include some
common blocks.
If a subroutine has the same variable name as a variable used in common
block it does not insert will its value change.
The other hack is to close and open the session every time I want to call
a subroutine.

COMMON /AHC1/ AHCOMMON1 COMMON /AHC2/ AHCOMMON2 That way there won't be any conflict between the two blocks.

Re: [U2] UniObject .NET Session and Common Block Bug
Hi Adrian I've never seen this particular issue before. What release of UniVerse or UniData is this (likewise the clients too)? What OS/platform is your U2 installation on? I would suggest some of the following to assist you in drill down the root cause: a) Execute a DIVERT.OUT or COMO ON (or call !COMO) to capture the host sessions standard output errors. Sometimes you can see the actual error in your output file (if there is any additional errors output) b) Check the VOC entries for the subroutines you're calling c) Call the subroutines as globally catalogued subroutines (CATALOG BP *MYSUB).. see if there is a difference Regards, David ** IMPORTANT MESSAGE * This e-mail message is intended only for the addressee(s) and contains information which may be confidential.

Hi All Within an execution environment, all subroutines using a given common name, including unnamed common, must have each common the same size as every other subroutine in the same environment, otherwise you get a COMMON SIZE MISMATCH ERROR. That is why, when you have 2 includes containing unnamed common, and include one in one subroutine and both in another, you get the common size mismatch error.

Re: [U2] UniObject .NET Session and Common Block Bug
Adrian: An unnamed common is not lost between subroutine calls. It is only lost when a program (not a subroutine) completes execution. So, If I run PROGRAM1, set unnamed common within it, then call SUBROUTINE1, then call SUBROUTINE2, unnamed common is kept until PROGRAM1 completes execution, even though SUBROUTINE2 completed execution then SUBROUTINE1 completed execution. This is where you have to be careful with non-telnet connectivity. Sometimes, a product has a BASIC subroutine listening at the U2 end then CALLS the subroutines specified. In this case, the use of all common has to be thought about. Bill Adrian Halid said the following on 10/7/2009 11:36 PM: Thanks for the help. It seems once you name your common block you do not get the error anymore. Just having a read of the documentation about the common statement in the documentation.

Re: [U2] UniObject .NET Session and Common Block Bug
Just an update with common blocks.
What I am doing is calling two different subroutines with the same UniSession.
The first Subroutine inserts 1 common variable to the common block.
The second Subroutine inserts 2 common variables to the common block.
I am calling these subroutines consecutively and not nested.
This means that after each subroutine call the common area should be lost and
therefore I should not get a common miss match exception.
From UniVerse BASIC Reference
A common area can be either named or unnamed. An unnamed common area is
lost when the program completes its execution and control returns to the
UniVerse
command level. A named common area remains available for as long as the user
remains in the UniVerse environment.
I decided to compare the difference between UniObject .NET, VB6 and Java.
The results are as follows.
UniObjects VB6 and Java
Can use the same session to call subroutines consecutively.
The common block is cleared after each subroutine call.
UniObjects .NET
Can NOT use the same session to call subroutines consecutively.
The common block is not cleared after each subroutine call. Causing the second
subroutine to not load and throw and exception.
This to me sounds like a bug in the .NET implementation of UniObjects.
Example code for .NET, VB6 and Java can be found via the link below.

SUBROUTINE SR.AHTEST.CALL1
COMMON AH1
RETURN
END
SR.AHTEST.CALL2-

RETURN
END
Below is the same example in Java
import asjava.uniobjects.*;
public class test
{
public static void main(String [ ] args)
{
System.out.println(Start);
try{
UniJava objUJ;
objUJ = new UniJava();
UniSession ahsession = objUJ.openSession();
ahsession.setHostName(HOST);
ahsession.setUserName(USERNAME);
ahsession.setPassword(PASSWORD);
ahsession.setAccountPath(ACCOUNT);
ahsession.connect();
UniSubroutine ahsub1 =
ahsession.subroutine(SR.AHTEST.CALL1, 0);
ahsub1.call();
UniSubroutine ahsub2 =
ahsession.subroutine(SR.AHTEST.CALL1, 0);
ahsub2.call();
}catch(Exception e){
System.out.println(e.toString());
}
System.out.println(End);
}

[U2] UniObject .NET Session and Common Block Bug
Hi All,
I am trying to call 2 subroutines using the same session in UniObject .NET but
have an issue when the second subroutine Inserts a larger common block.
I call the first subroutine without any issues. But when I call the second
subroutine I get the following error.
[IBM U2][UODOTNET - UNICLIENT][ErrorCode=30105] Unable to load the subroutine
on the server
I only have this issue in .NET and not in VB6.
I believe that the .net UniSession is storing the Common Block variables and
when I try to call another subroutine with a different common block it fails to
load.
I have read in another post on the web that people have created a Common Block
loading subroutine to load all Common Blocks when they create the session.
This way when ever they call any subroutine they know the common block does not
increase.
This seems a like a hack to me.
I am worried that when ever a developer creates a new Common Block that they
have to remember to update the Common Block loading Subroutine.
Also we have thousands of Subroutines that may or may not include some common
blocks.
If a subroutine has the same variable name as a variable used in common block
it does not insert will its value change.
The other hack is to close and open the session every time I want to call a
subroutine.
But once again this is not suitable for my application.
Here is my common blocks in universe

Hi Adrian I don't have problem with named commons. There is a problem if you update the parameters in a named common and you do not compile all the subroutines with the named common. If you call a routine that has not been recompiled you get a fatal, named common mismatch. Is that a possible issue for you. This is a general basic issue and is not an issue with .Net API.
