Debugging a tuxedo service using dbx
Hi,
Is is possible to debug a tuxedo service using dbx by enabing the tmboot switches
and -g option of the compiler. I am able to step into tpsvrinit during initialisation,
but not able to do when a client calls a service. I could not step into the service
by setting breakpoints. Please help.
rgds,
Dominic
The only thing to be aware of is that while you play around in the debugger, Tuxedo
is timing out your transaction.
So, if you want things to keep working while you debug, setup some nice long timouts.

I have not done this on Solaris in a while but basically, what you have
to do is
to build the process with -g and start it with tmboot as you would normally.
After the process is running, you can attach by typing:
dbx name pid
where the name is the name of the executable and pid is the process id
of the
server process (obtained either with ps -ef | grep name or with verbose
mode psr
in tmadmin). This will break into the running process. You can then
set your
break points in the service routines as required. When the service is
entered,
control will return to your debugger session and you can debug as you
normally
would.
Incidentally, I find the buildserver -k (keep) option to be useful when
debugging
servers. This allows you to debug through the startup code that is normally
deleted
as a part of the buildserver process.

Any clue on this.
With Regards,
MVSIf you are trying to create a Tuxedo service in Java using WTC you need to develop an EJB that implements the TuxedoService interface and register its home in JNDI so WTC can look it up. Once that is done you can then export the service to a remote domain in the WTC configuration.

Debugging of Tuxedo Service in C/C++
Hi All,
I am trying to debug tuxedo service (C code on HP-UNIX 11.00) in the following ways :
shprod25 48: gdb csbfp001 -> csbfp001 is the application service exe
(gdb) b GetRecircRow -> GetRecircRow is the function name
(gdb) r
Starting program: /appl/bstar/bin/csbfp001
Error while reading dynamic library list.
(gdb)
Looks like it is not able to read DLL and it exists. Can anyone please tell me how can i debug the code line by line ?It's even more complex than this, because Tuxedo Services has to attach IPCS and register in the BBL/DBBL in order to communicate with the world. The problem you are facing is because you are trying to boot the server without all the variables that tuxedo programs (like tmboot) uses when starting all the stuff.
So, I will recommend you two different aproaches:
1) Start tuxedo server as usual (with tmboot a/o tmadmin) and attach gdb to the pid when it has started, debugging from then on. It is the easiest and safest way.
2) If you need to debug from the start (which is a little more complex), load the environment that starts initially the domain (BBL/DBBL), start tuxedo server as usual, take note with a "ps" of all the parameters tuxedo uses when starting this server, shutdown it and start debugging with gdb using this parameters to run the server.
Hope this helps.

You can't do that with JOLT. You will need to use the WTC product,
currently in beta - see WTC Questions and Answers

Hi All ,
Is it possible to debug Tuxedo Services using GDB in Unix environment (AIX) ..
Could you please share your experience in this regard
Thanks in advance
Nadeer.Nadeer,
Yes, it is possible to debug services using GDB. To get the most debugging
information, you should "export CFLAGS=-g" when running buildserver so that
your server will be compiled with debugging on. After booting the server,
you can attach to the running server using "gdb myserver process_id" and set
breakpoints. After setting breakpoints, you can give the "continue" command
and send a client request to the server.

TPESYSTEM error when calling tuxedo service
Hello,
I have a problem when running my own EJB as a TUXEDO service using WTC.
Im using TUXEDO 8.1 and WL 8.1.
My TUXEDO and WTC configuration seems OK, because TOLOWER example is running OK.
When im trying to run my own EJB as a TUXEDO service on TUXEDO side TPESYSTEM
error appears.
JDNI name and configuration of the EJB is correct, because when I put wrong JNDI
then on TUXEDO side TPENOENTRY error appears. Additionally - my EJB's bussines
logic is pretty the same as TOLOWER example.
I think that is EJB issue because in server logs there is an information that
domains are connected but ejbCreate method isn't called. My EJB was developed
using JBuilder 9 WebLOgic Edition and WL Workshop 8.1.
Thanks,
PatrickHi Hemant,
I'm not sure, but my guess is it was a setup problem. Perhaps not implementing the right interface in the EJB, not having the correct home specified, etc.
Usually the best way to find these errors the first time is to turn on some debugging information in WLS. More information can be found at: http://edocs.bea.com/wls/docs91/wtc_admin/Install.html
For this sort of problem, it probably makes sense to enable -Dweblogic.debug.DebugWTCGwtEx=true and/or -Dweblogic.debug.DebugWTCJatmiEx=true
The above examples are for WLS 9.1 and later. For earlier releases of WLS, check edocs for the settings of weblogic.wtc.TraceLevel

Troubleshooting tuxedo services .. related to Oracle deadlock errors
Afternoon all,
I support an application that allows API calls to tuxedo services using messages comprised of FML fields. Our application sits on an OracleDB that is experiencing deadlock issues, one of the tuxedo servers involved in the deadlock is one that advertises services accessed by the API calls so I'm trying to rule it out as the source.
Is there any way to trace/log the services in detail so that I can tie the deadlocks directly to a call of a tuxedo service?
I've looked into TMTRACE, but I'm not sure this is going to give me the detail I need.
Changing application code is not an option unfortunately.
Thanks,
AdamHi Todd,
Thanks for the quick response.
Aplogies for the ignorance, but what do you mean by XA / local database transaction?
Our architecture is such that a tuxedo server, that offers the services our APIs talk to, makes the Oracle updates. Is that XA or local?
Oracle's logging and deadlock messages show me what the updates are, but I'm trying to make sure 100% that an API called service is instigating that update.
Hope that is clear enough!
Cheers,
Adam

Hi Adam,
Are the Tuxedo services using XA transactions or only local database transactions? The reason I ask is that TSAM offers the ability to track XA transactions and might be able to tell you what's happening. It can also track services and call paths, i.e., complete end-to-end call tracking from a Tuxedo client, through intervening servers (services).
If you are not using XA transactions, I'm afraid there isn't a lot that Tuxedo can provide you as Tuxedo is unaware of the underlying database requests. In fact, if you aren't using XA transactions, Tuxedo doesn't even know a database is involved it the processing of requests.
I would think you should be able to trace things from the database side, but you'd have to ask that question over in the database forums as I'm not familiar enough with what tracing/debugging facilities on the database side to give you much help.

Can i write a tuxedo service using JAVA...does tuxedo provide APIs for that ?
Hi,
You can build any binary executable that calls Java and vice versa, using JNI, but then, manageing a tpreturn(3c) without getting back to the C stub sounds dangerous, when you know what tpreturn(3c) does (longjump). Put your JavaCose Caller C Function in a library, and it can be called from any C code.
Then you need to be aware that you loose some good points of Java: How can you make a ThreadDump in that context?
Also it rises new basic questions: Will Java's Multiple threads interfere with Tuxedo MultiThreaded server-side architecture? How can all the threads of your server safely share the same JVM instance? What about the classloaders? The Database connections? The XA Interface?
But if you do so, be warned about the memory leak problems you may face. Some products use that technology, but have to commit suicide every 10000 requests to avoid memory leaks.
I would strongly advice you to benchmark your executables so as to prevent that from happening...

Judging by WS6U2 above, I assume you are using dbx 6.2, which is very, very old. Unless you need it to work on similarly old Solaris, please consider upgrading to Sun Studio 11 (supports Solaris 8) or Sun Studio 12 (supports Solaris 9+). Both are free and contain many improvements.

However, I can not resume the service process either. when I use cont command, the dbx seems to stop there with no input prompt.That's kind of expected behavior from the debugger - it resumes debuggee and sits there until debuggee generates some event (like hitting breakpoint or receiving a signal). Once dbx gets notified of this event, it presents details to the user and provides input prompt.
Did you put any breakpoints in (with stop command)? You'll also need to make sure breakpoint is reached by that service you are debugging.
Anyways, if all you need is to trace the service, it might be easier to use truss(1) command like this:
$ truss -p `pgrep Tuxedo` -
How to deploy and debug java web service in eclipes or using any other soft
Hai,
can any one tell me how to deploy and debug java web service in eclipes or using any other software.
i have used tomcat web server and jdk1.4.0 to develop web service.
we have used web service to interact with MS outlook .
bye
sudhakar.mHi Sudhakar,
If you are used to working with ant then you can very well use eclipse to deploy your web service.
You would usually have the ant script in the source root working directory. From eclipse if you select the build file from the navigator view and right click you will see a run ant option in the pop up menu.
Select that option and you would be able to see each targets with a checkbox select option. So define each target maybe one for wsdl2java conversion, one for compilation and one for deploying your web services. You can either make all of them run by having depends option on or you can run them individually as it takes your fancy.
I am not sure about debugging a web service yet.
Hope this helps

Is it possible to modify SQL DB tables using TUXEDO services???
Hi,
I dont know how to use to resource manager to connect to the SQL Server Database
nor have I ever worked with SQL Servers.
But you could possibly try doing the following.
In the Tuxedo Server / Service, using Pro*C, you can use the
EXEC SQL CONNECT :userid IDENTIFIED BY :password statment.
This should open the connection to the SQL Server DB. and then using the regular
Pro*C SQL Statement you should be able to do modify the tables.
But please be sure that the user id you use has the Insert/Update/Delete rights
on the tables that you access.
I hope this helps.

Thanks you very much for your advise.
[roll.ec]If ud32 reported a syntax error, then your service was never called.
Normally, a service running under XA control should not issue transactional SQL
statements. Begins and Rollbacks are issued from the transaction manager, not the
application code.
Can you post the Tuxedo message catalog number, and your ud32 script, as well as
your environment variables?

Hi
I have a task assigned to debug an application which is using multithreading and written in c.
Sould you please help me how i can debug a Daemon written in c.
If i donot have to use DBX then i will simply run my program as:
nohup /dir1/dir2/executable_name /dir1/file_name
The code is complied with -g option.
But what i'm not sure is how i will execute the binary from DBX and with the paramtere (file_name).
Help is greatly appreciable.
Thanks.First of all, run command cannot be used for debug target specification, it accepts parameters that you want debuggee to run with. In order to specify program to debug, use debug command like this:
(dbx) debug /path/file_nameAlso, you don't have to run a program from the dbx in order to be able to debug it later.
You just do
$ nohup /path/file_name &
Sending output to nohup.out
$ pgrep file_name
12345
$ dbx - 12345And dbx will attach to recently started program with pid 12345.
If you need you daemon to stop before main, then you can simply use debug dbx command as usual, no nohup is needed. If you need i/o redirected, use > like this:
(dbx) run > log (there's no way to redirect stderr, only stdout).
And remember: run command is for starting the program, debug command is for specifying which program to start. -
Hi everybody,
I wrote a "Class Library" project which is a service using Visual Stodio 2008 recently, then tried to use a Visual Studio 2008
Setup Project to install it.
Here is what I did for the "Class Library":
1. Finish the program.cs, Service.cs
2. Add Installer
3. Change the serviceInstaller so that "StartType" to be Aotumatic
4. Change the ServiceProcessInstaller2 so that "Account" to be LocalSystem
5.
6. Click in F5 (Start Debugging)
Here is what I did for the Setup Project:
1. Add the exe file built from the "Class Library" project to the Application Folder
2. On the Custom Action Editor, add the exe file from 1 to Install and Commit
3. Change the property of the project so that "RemovePreviousVersion" to be true
4. Click on F6(Build Solution)
Then I tried to run the msi file from the built of the Setup Project. Because I modified the two projects serveral times, I uninstalled the Class Library using "Control Panel->Add or Remove Programs" before I reinstall. Two things I notived:
1. After unstall, the registry was not cleaned up about the installed program
2. After several rounds install/uninstall, I got "Error 1001. The specified service already exists"
My questions are:
1. How to cleanup the registry when uninstall a program?
2. How to deal with the "Error 1001. The specified service already exists"?
3. Did I do anytbing wrong with the "Class Library" or the "Setup Project"?
Thanks a lot!
HelenHi Simon, not a problem!
I spent some more time on this and here are few more notes:
it is called Major Upgrade, when you are installing new version of the product upon a previous one and
MSI supports 2 strategies:
Strategy 1. Install a new version and uninstall previous one. (Install a new version right upon previously installed version (file merging is performed based on dll version number) and the delete previously
installed files)
Strategy 2. Uninstall previous version and install a new one (Delete all previous files and install from scratch new files.)
From the first look it seems that 1st strategy is weird and buggy. But, remember, MSI is great because it's transactional!!! That means that if once some of the phases (Installation, Uninstallation, Rollback, Comit) fails, your machine
will be reverted to the previous state and it'll be still functional.
Let's consider both strategies:
Consider you have installed product_v1.msi and you want to install product_v2.msi.
Strategy 1
1. MSI engine copies files from Product_v1 directory to TEMP directory
2. MSI engine merges files based on the assembly version (between v1 and v2)
3. Once merging is completed successfully it removes files in TEMP (RemoveExistingProducts action triggers it) and you got product_v2 installed, otherwise if it fails MSI engine revert machine to V1 and copies previous files from TEMP.
Strategy 2
1. MSI engine tottaly removes all files from v1.
2. MSI engine installs v2 files and if something goes wrong you cannot revert back, because RemoveExistingProducts allready worked out and MSI doesn't have files to revert machine back
I recommend to everybody to use Strategy 1 and leverage MSI transaction functionality. And you can set this strategies by defining sequence of RemoveExistingProducts action. See more info
here. So, I think it's not even a bug in VS as I said in the upper post it is default recommened behaviour.
AND, you got "Error 1001. The specified service already exists"
because if we follow Strategy 1 MSI engine tries to install Windows Service on top of the existing service and OF COURSE it fails MSI engine (StopServices, DeleteServices actions are executed before actual
installation and they look at ServiceControl table). In order to stop service first and delete them you have to fill ServiceContol table of the MSI (and then StopServices, DeleteServices actions will recognize what to they have to stop
and delete), like this:
*clip*clip*clip*
' see http://msdn.microsoft.com/en-us/library/windows/desktop/aa371634(v=vs.85).aspx for more info
' Update the Service Entry to stop and delete service while uninstalling
query = "INSERT INTO ServiceControl (ServiceControl, Name, Event, Arguments, Wait, Component_) VALUES ('MAD_Service', 'Service name', '160', '', '1', '"
+ componentName + "')"
Set view = database.OpenView(query)
: CheckError
view.Execute : CheckError
' Update the Service Entry to stop and delete service while installing
query = "INSERT INTO ServiceControl (ServiceControl, Name, Event, Arguments, Wait, Component_) VALUES ('MAD2_Service', 'Service name', '10', '', '1', '"
+ componentName + "')"
Set view = database.OpenView(query)
: CheckError
view.Execute : CheckError
*clip*clip*clip*
We can uninstall service first by following Strategy 2, but then we lose transactional support.
So, Simon did I encourage you to change your code a bit?:)
And, btw, if you don't want to change the strategy, please don't rely on SequenceID in MSI table, it can be change, you have to get the at the runtime.
Hope it will help to everybody!
