Sheduled jobs on redunant application server environment

I've been taking a brief look at running sheduled (housekeeping) task in an environment where we have multiple redundant app servers (Oracle, for our sins).
These servers are coupled so that deployments propagate automatically.
What I was wondering was - how would you shedule a Timer so that a housekeeping task was run on exactly one server. This should cope if one of the servers is down at the time sheduled. Are there facilities for this?

SuperScheduler and SuperWatchdog: a task will be executed once and once only. You can visually set a URL task or use SuperPeekPoke to visually set an EJB task. See http://www.acelet.com/super/index.html.

Creating Oracle Application Server Environment?

Hi All,
i am new to AS
i need to know the way that i should build my Application server environment
suppose i am a company that sells a software package, i have 2 clients for this package
so i should install
1 infrastructure (for both clients)
1 middle tear (for both clients)
2 application servers ( 1 each)
please help as i asked a lot of questions before and no one reply me, it seems that this forum is not very active like the DB Admin one
Thanks for any contribution

If you are actively supporting 2 clients, but the codestream for each is the same then you really only need one AS... just use 2 databases and access the relevant one depending on your url parameters.
You could create seperate AS but sounds like overkill to me.

Mixed application server environment with z/OS

Hello,
I'm looking for more information from SAP when running a system in a mixed application server platform environment. In other words, the system would look like the following:
1. Central instance (only MS and EN processes - i.e. standalone enqueue) running on AIX
2. Dialog instance (disp+work processes - i.e. spool, batch, dialog, upd) running on Windows 2003 or Linux
3. Database running on z/OS
I see from the Product Available Matrix, that Windows and/or Linux are supported with z/OS, but there is no mention of running a mixed environment as described above.
Any help/guidance would be appreciated.
Regards,
David

Yes, we have already been down the road of zLinux. Thanks to some pricing issues on the DB2 z/OS side, we had to give up our IFLs and thus zLinux. Our application servers are now on Windows 2003 x64. Even when we were on zLinux, we were forced to run some Windows application servers for Adobe Document Services as this is not supported on zLinux and SAP/Adobe have thus far refused to port it.
The inconsistency is that while SAP says it is "ok" to use something like SAMBA to share out SAPMNT and have it work under windows, it introduces unneeded complexity in many areas. SAP note 680617 describes this process. For us, it was a neverending headache with the unix vs windows text file format differences (supposedly handled by instance parameter abap/NTfmode=b) and there are complications for path names for batch jobs, etc.
I am sure all of those issues can be sorted out eventually, but it is just much easier to stick with one application server platform.
If you're considering zLinux, I would be extremely careful. There are only a handful of SAP customers in the world running it. Most likely you'll run into problems that no other customer has encountered yet and which will require a PTF or a new SAP kernel to fix (when you can finally get them). We ran into one such problem communicating to the ASCS/SCS in USS from zLinux over hipersockets. This really plagued our project team with hung locks (especially during LSMW imports of master data) until SAP released kernel 150 for zLinux which coded around the "unexpected" extreme low latency of hipersockets.
Caveat emptor.

SNC configuration in multiple application server environment

Hello Experts,
We are planning for SNC configuration between ECC 6 and NW04s Portal systems.
ECC 6.0 is running with Central Instance and two application servers.
NW04s EP is running with 4 server nodes.
I am very much clear about setting up SNC between ABAP and JAVA running with single application server and server node.
But totally confused about SNC/SSL setup in multiple server environment. Would really appreciate if you can provide some ideas/docuements on setting up SNC/SSL in multiple server environment.
1. Do we need to create multiple PSE for each of the ABAP application server? If yes then would the CN should be same or different.
2. If we create only one PSE for central instance and copy this to other application server - will this work.
Looking forward to hear from your experiences.
Regards
Davinder

I have installed Oracle As (infratructure & middlie tire) on same box.
10g Release 2 (10.1.2)
Now I need to do post installation steps as below.
ORACLE_HOME
1) How to set to the full path of the installation's Oracle home?
2) Do I need to also set ORACLE_HOME for middle tier?

Hello,
I have installed Oracle AS Infrastructure (10.1.2) and BI & Forms on our Linux box.
Now I am doing some post installtion steps .
Per Oracle® Application Server Quick Administration Guide 10g Release 2 (10.1.2) B14126-02
\http://download-west.oracle.com/docs/cd/B14099_10/core.1012/b14126/toc.htm
**Set to the full path of the installation's Oracle home
ORACLE_HOME=/opt/oracle/infra; export ORACLE_HOME
** Set to the OracleAS Metadata Repository SID you supplied during installation.

Including DLL in application server environment

Hi.
I'm running my application under JBoss Apps Server 2.44. I need to use a tool call Bridge2Java to access some DLL files. In order to install Bridge2Java, you will need to install in not only java classes but a DLL file as well. I managed to deploy the java classes but have absolutely no idea where to put the DLL files. I've tried within the bin folder but that doesn't work. Also tried to deploy with the application - doesn't work either. Anyone has any ideas?
Thanks in advance!
Meng.

Should work if you put it in any directory that exists
in your PATH environment variable.Restating that slightly...
It must be in the PATH environment variable of the environment under which the JVM runs. That might not be the same as a user, as servers usually end up starting up as a service. And since each service can have a different user or no user at all, that has to be checked.
I believe you can also put it in the execution directory. But figuring out what the execution directory actually is can sometimes be very difficult.

Running "scheduled jobs" in an application server

Hi, I'm working on a project where we run some middleware integration software on websphere 5. What I need to create is a component that really is a thread that polls a database table and pull out the data, format it and send it to another system if there's any data available in the table. This is relatively easy using a standalone application, but I'd like this to run inside websphere so we don't have to manage a new application, just a new component in the app server. But on the other hand, manipulating threads (for sleep, etc) is not a thing one should do in an app server. So, does anyone have an idea for an elegant solution for doing this task inside websphere?

What about JBoss? Can you implement the "timer" from this app server? I'm doing the same type of thing, but using JBoss.
Also, why do you say that you shouldn't manipulate threads from inside an app server?

Generate Application Server Load Through Siebel Jobs

I am interested in scheduling a simple job that would tax the CPU of the application server. I can schedule many jobs, such as admin notify, which barely tax the cpu.
Peoplesoft had some called the simpleAEtest job that I executed on the process scheduler, for a similar need.
It would be really great If I could configure this job from the command line server manger until,.
What do you guys do for siebel load balancing and stress testing?
I have a test siebel Application server environment configured with the following:
Siebel 8.1.1
Database Server, Oracle 11g
Gateway Server, Windows 2003
Application server, Windows 2003 running the following components
Callcenter, Sales, and ADM
There are so many jobs and parameters, its hard to short out what parameters to use.
Thanks for the help

Hi Sergiy,
We currently have the Scheduled Tasks turned off so I know that it is not causing the slow down. I also know that we do not have any custom code that is hitting those tables, as I am the only one that is doing any of the customization.
However, you bring up an excellent point with regards to other Activities. We have noticed that this does not occur at specific times so that would suggest it was not on some sort of schedule so perhaps a certian Activity is the cause. You mentioned "RMA SFC Receipt", could you find out if there are any other sorts of Activities that may cause this while I look into this one?
I will perform some tests on our Test machine with the "SQL Trace" and "Debugging Information" turned on as you suggested.
Thanks,
Mike

Download to application server using job open/close

Hello people,
Currently I am using open/close dataset to download to the application server automatically. What I do here is submit a program execute in background when the report is done the report is automatically downloaded to the application server.
My problem now is that I want to use job open/close. With this, unfortunatley, my current method of open/close dataset will be unsuable to download to application server once the background job is done.
My question is, is there a way for me to automatically download a file to the application server using the job open/close method?
Thank you so much and take care.

<b>Hi,
What you can do is to write a report program that downloads the data to the file on the app server.
Now, you can use the JOB_OPEN and JOB_CLOSE and submit this program in the background which will write the file.
Regards,
Ravi</b>
So what you are saying is that I create two programs, where the job open/close program is the one I will run?
Problem is that I plan to get the values of the selection-options from the original program using the program with the job open/close. How will that work.
Thanks

How to get the list of batch jobs running in a specific application server

Hi Team,
I am trying to check in SM37 if there is any specific condition to get the list of batch jobs assigned to a specific target server but cant find any.
Is there is way to find the list of batch jobs assigned to run in one specific application server.( Target server specified in SM36 while job creation)

Hello,
This is what you can do in SM37.
Execute the list of batch jobs, when the result appears on the screen edit the ALV grid via CTRL+F7.
Now add the following columns "TargetServ" and "Executing server".
You will now have two extra columns in your result list.
TargetServr contains the value of the application server where the job should run when you have explicitely filled it in.
Often this is empty, this means that at runtime SAP will determine itself on which application server the job will run (depending of course where the BGD processes are defined).
Executing server is filled in always for all executed jobs, this is the actual application server where the job has run.
You can also add these two fields in your initial selection screen of SM37 by using the "Extended job selection" button.
I hope this isusefull.

Deploy to Application Server Failed on a distributed environment

Hi All,
I am trying to configure new Hyperion verion 11.1.2.2 on distributed environment but during configuring calculation manager to application server failed and getting error message like "Deploy to Application Server Failed". I am not sure what is issue and how to fix it. I have tried to read log files but I am not able to undersantd where to look and debug this issue.
My Hyperion Environment over view as a below:-
1- I have used Microsoft VMWARE to build my Hyperion Enviornment
2- I have created 1 window server 2003 domain and made 4 clients of that domain. (All these systems have windows server 2003 installed). I have given name to each client server i.e. System A, System B, System C, System D
3- I have installed SQL 2005 and created databases for all Hyperion components i.e. Shared services, calculation manager, epma on a system A
5- I have installed and configured foundation services and weblogic server on a system B. (In this system I have installed and configured shared services, weblogic, workspace, and able to deploye application server on a same system)
6- On a system A I am able to complete installation for hyperion Performance Management Architect and Calculation Manager and able to finish all type of configuration for these two components but as soon as system trying to configure any related to APPLICATION SERVER services it fails to configure. On a configuration summary page system shows everything is configured but APPLICATION SERVER says FAILED wrtten on a red color letters.
I have explored log files and found that Calculation Manager application server failed to deploy or Deploy to Application server failed.....
Since, I am not sure where to look and how to debug this issue I am requesting to all hyperion friends to help and guide me to debug as I have been trying to install this product since last friday and still no out put....
I will be really thankful if someone share his or her wisdom to help me....
Thank you to all in Advance.....
Thanks,
Safi

Did you install all the WebLogic web applications on the foundation machine as well as the machine they are going to be deployed to.
"On the machine on which you plan to administer the WebLogic Server, you must install all Web applications for all applications you plan to deploy on any machine in the environment. (The WebLogic Administration Server is installed and deployed on the Foundation Services machine.)"

External commands fail in Background Jobs on Application server

Hi,
We are having problems with jobs that include External Commands. The jobs run successfully if on the Central Instance. But if they run on either of the two Application Server's it fails with 'Unable to connect to Target Host' error message.
I can run the External Commands from SM49 on both AS's. But as soon as its run in background it fails.
I have read the rfcexec.sec file needs to be in the .\work directory on the application so I have this in place.
This is what gets written to dev_w0 when the failure occurs :

Hi Siddhesh,
Thank you for your prompt response. I'm confident all of the prerequisites are set correctly.
I have enabled the trace on SAPXPG but its only writing to the log dev_cp and dev_xpg when the command is executed successfully.
For example, if I use SM49 to run the External command from one of the Application Servers dev_cp & dev_xpg are updated and the command completes successfully. However if I run the job (that has the external command as a single step) from SM37 it fails and doesn't log anything to dev_cp or dev_xpg??
Is this normally how the trace would work?
Thanks again,
Kye

All the DTP jobs are routing to one application server

HI all,
DTP process job is triggering 3 child jobs all those child jobs are going to one application server, we have many DTP jobs all the jobs are routing to one paticular server that is causing application server to be hang(high cpu, memory utilization) .could you please suggest me in the process chain, is BI team can assign the application, i am not getting why dtp child jobs are executing only one application server, i have obesereved since 10 days it is happening. could you please suggest me how we can over come this.
Thanks & Regards.
Venugopal

Check tcode RSBATCH, If I'm not wrong DTP_LOAD process type is assigned to application server on which these DTP jobs are running. Remove that application server name and save.
Again use RSBATCH, under 'Background and Parallel Processes' tab, click 'Switch Off F4 Popup for Server/Host/Group', enter *** (star) under Users for 'Users for Whom NO Server/Host/Group Popup Should be Processed'. Now activate the PC and execute and check the DTP jobs.
Since u have 4 Appln Servers, best bet would be creating a server group. See the below link.
