Starting multiple application servers

We have 4.7 system has 2 application servers as "sap1" and "sap2" installed in different Unix servers.
I would like to start "sap1" first and "sap2" next. Is there any standard script for starting multiple application servers in a sequence. We have problem, when restarting servers after weekly off-line backup. Should we go for customised Unix shell scripting?.
Thanks,
Sam

#!/bin/sh
SYSID=ABC
STARTSCRIPT="/sapmnt/$SYSID/exe/startsap"
start the Central Instance (CI)
$
start AppServers
remsh <app server> -n startsap <Instance name>
stopscript
#!/bin/sh
SYSID=ABC
Stop all app servers and the database.
stop AppServers
remsh <hostname> -n stopsap <instance name>
stop central instance
/sapmnt/$SYSID/exe/stopsap
Thanks,

Session cleanup issue with multiple Application servers

Hi ,
I am facing a strange problem with multiple application servers. The java Webdynro session does not get cleaned up completely when user closes the browser ( without using logoff ). On re-login it gets handle of old session and then fails for consecutive view on other webdynpro iviews with an invalid session error. It again starts working with a refresh event.
Any ideas/suggestion if you have seen something similar before ?
Thanks and regards,
Amit.

Hi Amit
It seems that issues is not server related, but caused by your client browser. I know, for example, that IE8.0 keeps user session even if two separate browser instances opened on the same client machine. IE 7.0 and lower behave differently - they are separate user sessions per browser instance.

Issue of multiple Application servers

I have a report which submits 5 reports(with Return
) inside it. Now if I have multiple application server then I do not know which server the job will get submitted and currently in my landscape the synchronisation time between the servers is 2 mins. Problem is some of my subsequent reports is dependent on the prev one and due to this if next report is getting called in diff application server before the sync then it is failing.
I have thought about open job and close job while submitting reports because in open job FM you can specify server but then I need to wait in main program till the report finishes.
Is there any solution more elegant ? or am I missing something ?
Regards
Somnath

Create 5 different jobs for all 5 different programs through JOB_OPEN, SUBMIT, JOB_CLOSE FM.
You can set the start date / time for the first job.
For the all rest jobs you can make them dependent on its predecessor job's status.
You can use the parameter PRED_JOBNAME and PRED_JOBCOUNT of the JOB_CLOSE FM to set the predecessor job. You can set the PREDJOB_CHECKSTAT to make it state dependent.

Load balancing across multiple application servers not working with JCo RFC

We have a problem where inbound messages to the Mapping Runtime engine (ABAP -> J2EE) are not load balanced over application servers. However, load balancing does take place across server nodes within one application server.
Our system comprises of the following:
Central Instance (2 X server nodes)
Database Instance
2 X Dialog Instances (with 2 X server nodes each)
The 1st application server that starts is usually the one that is used for inbound messaging.
We have looked at the sap gateway configuration and have tried various options without much luck:
i.e.: local gateways vs. one central gateway, load balancing type by changing parameter gw/reg_lb_level, see: http://help.sap.com/saphelp_nw70/helpdata/EN/bb/9f12f24b9b11d189750000e8322d00/frameset.htm
Here are our release levels:

WebDynpro Notification Service with multiple Application Servers

Hello Experts,
I am currently working on a project where I have to integrate a BSP Application into a new Web Dynpro ABAP Application. On the BSP Page it is possible to edit some details (for example for a customer).
When the user start to work on the BSP Page, the Web Dynpro Page should prohibit the navigation (i.e. disable all links). After Saving the BSP page, the navigation lock is released and the Web Dynpro reloads some data, which were changed from the BSP Page.
I have a NetWeaver 7.02 so I decided to use Shared Objects and the new Web Dynpro Notification Service to realize the given requirements. On the development system everything worked fine. The Notification Service was called and it took about 2 Seconds until the Web Dynpro Application updated.
But we got serious problems on the testmachine, which uses a Web Dispatcher and two application servers. After some research we managed that the application is running, and works.
But the Notification Service takes now up to 1 Minute until it fires the registered actions. And I good frequently an ASSERTION_FAILED from the method CL_WDR_NOTIFICATION=>ATTACH_FOR_READ in the ST22 as long as the application is running.
Can anybody help me how to solve this issue. It is a real blocker for the project.
If there is another way to establish eventing between Web Dynpro and BSP I would also go for another solution. But I don't think there are many other possibilities (SAP Portal and NWBC are no options - Maybe the new Web Dynpro PageBuilder?).
Best Regards
Daniel

Hello Guys,
we decided to do a workaround for the moment. We use a refresh button on the Web Dynpro screen. That is not very nice, but sufficient for the moment.
Anyway: I am still interessted in the BSP-Web Dynpro Interaction Issue. So if somebody has any ideas, please let me know.
@PageBuilder: Currently the page builder does not work on the system, because of an 403 - Error when I try to call the Application-Configurator (the SICF service is active). But I will try this also as soon as this problem is solved.
Best regards
Daniel

Top Essentials Cache and Multiple Application Servers

Hello,
I'm developing a new servlets/services application in Java using tomcat and playing around with toplink essentials. Is it possible, when using multiple servers, to expire cached objects? Eg I update user account info on server 1, but 2 and 3 still have old data. The documentation and blogs I have read seem to indicate you either have to force a refresh of the object or set up readAllQueries to go direct to the db (which rather defeats the purpose of having a cache?) - for fresh data. Though I agree there are some places where up to the moment data is not always required, building a system to scale with expiry caching across multiple app servers seems like something toplink essentials SHOULD be able to do.
Also, is there any work on when the new rev of Toplink Essentials would be out? I see posts about the 11G preview but that's regular toplink.
Thanks in advance!

There are several caching options in TopLink Essentials to handle stale data.

Some of the settings are available through properties in the persistence.xml, but for most you will need to use a DescriptorCustomizer or SessionCustomizer and use the API of ClassDescriptor (refer to JavaDocs for additional info).

Caching options include:
- Cache Type : (weak, hard, soft, none), a weak cache will decrease stale data.
- Isolated (shared) : You can set the descriptor to be isolated or cache not shared to avoid caching the class.
- Refresh : You can enable refreshing at the class or query level.

A ClassDescriptor does have an invalidation policy, but the policies for invalidating based on a time-to-live or time-of-day were not ported from TopLink to TopLink Essentials, however you could write your own pretty easily.

If you upgrade to using TopLink 11g (preview), which you can download and use under the Oracle OTN license, then you have support for using cache invalidation and cache coordination. This functionality is also available in the Eclipse EclipseLink project currently in incubation.

Multiple Application Servers - Same class instance

Hi,
Due to increasing load we have to add multiple Web Servers and Application Servers (custom built) for our Web Application.
As currently we are using 'synchronized' for adding and releasing connection in ConnectionPool and also using static in several other classes - we have to make these few classes single instance across the application servers.
We are using iPlanet 6.0 for Win 2000. Is there any way we can direct specific classes for a single instance. Please provide me with all sorts of alternatives.
Thanks a lot,
Suman Biswas

Hi,
Yes, we have different JVMs. Different JVM means different processes,now there can be two cases,these process running on same machines
or on different machines.If it is in different machines then undoubtly you require to go for the Distributed Technology(RMI for java).
As we have couple of classes which are using
'synchronized' - cann't we use centralized classes for
these couple of classes to maintain integrity?Yes you can do it,now this centralized class should be available in common place from where your all applications can get results,and for avoiding the data corruption your require to go for synchronized(if some global variables) block,since the same instance will be serving all the requests.
When you say RMI - my question is how the commercial products handle these kind of issues while they are in multiple servers?I have created some application using RMI but not the same one which you had specified.I had used it for different purpose.

Check SITSPMON at multiple application servers at once

Dear Sirs,
we are in a setting with close to 10 application servers. To the memory consumption and current status on my system, I need to check SITSMON on every application server.
Is there an easy way to get a STISPMON like (e.g watch memory) on all the application servers in one go?
best regards,
Jørgen

Dear Jørgen,
at the moment we do not have an easy way to monitor more than one application server within SITSPMON. I am the developer of SITSPMON and happy to read your question. I do agree in your wish to have a feature like this.
How to implement? I would suggest to provide an additional check box in the dialog panes for
*the memory staistics,
*the HTML templates cache directory, and
*the Mutex lock statistics.
This checkbox allows to switch between 'system' and 'application server mode' checking it will result in an enhaced table, containing an additional column for the appl server...
Do you agree? Better ideas? If this fits to your requirement, I will implement this. And ideas are welcome always.
BTW: Did you already check the CCMS? There a technical experts monitor for the internal ITS. This might be helpful four you.
best regards
Tobias

Transactions over multiple application servers

Hello,
we have following situation.
We have a bunch of core services deployed on a central application server and some applications deployed on individual application servers.
The services are developed as normal remote interfaces.
The core service interfaces have special annotations, so the service locator knows, that he has to lookup them on other servers.
Now we have the following case:
This code is executed in application server 1.
Service2 is deployed in application server 2 and Service3 in application server 3.
public void doSomething() {
        ServiceLocator locator = ServiceLocator.getInstance();
        Service2 service2 = locator.getService(Service2.class);
        service2.doSomething();
        Service3 service3 = locator.getService(Service3.class);
        service3.doSomething();
}Each of the calls to service2 and service3 performs some database operations.
But, if service3.doSomething() fails, the database operations done by service2.doSomething() are not rolled back. (no surprise)
What do we have to do, so that the service2 operations are also rolled back on service3 failures?
Thanks
Dirk

Doesn't work... :(
Here my sample code:
Service1 (deployed on AS1)
@TransactionAttribute(TransactionAttributeType.REQUIRED)
    public void doSomething() {
        Logger.getLogger(getClass().getName()).info("doSomething");
        ServiceLocator locator = ServiceLocator.getInstance();
        Service1Entity entity = new Service1Entity();
        entityManager.persist(entity);
        Service2 service2 = locator.getService(Service2.class);
        service2.doSomething();
        Service3 service3 = locator.getService(Service3.class);
        service3.doSomething();
    }Service2 (deployed on AS2)
@TransactionAttribute(TransactionAttributeType.MANDATORY)
    public void doSomething() {
        Logger.getLogger(getClass().getName()).info("doSomething");
        Service2Entity entity = new Service2Entity();
        entityManager.persist(entity);
    }Service3 (deployed on AS3)
@TransactionAttribute(TransactionAttributeType.MANDATORY)
    public void doSomething() {
        Logger.getLogger(getClass().getName()).info("doSomething");
        Service3Entity entity = new Service3Entity();
        entity.setUuid("Bang");
        entityManager.persist(entity);
    }Each service has a XA datasource configured. The all access the same database.
But when I call service1.doSomething(), I get a javax.ejb.EJBTransactionRequiredException from service 2.
Does somebody has an idea?
thanks
Dirk

Portal pointing to Backend (Multiple Application Servers)

Hello Experts,
Landscape details : NW04s SP17 Portal for Travel Expense pointing to ECC 6.0 backend (running with 3 application servers). We don't have web dispather installed on the ECC 6.0 system, and client has no plan to install that also.
We have created portal system with Load Balancing template and using logon group (all 3 backend application servers are part of this logon group). In portal system, we have configured -
1. Connectors - using logon group.
2. User Management with LogonTicket.
3. ITS - pointing to specific application server - Can't we use logon group for ITS traffic going to backend
4. WAS - pointing to specific application server - Can't we use logon group for WAS traffic going to backend
In ESS/MSS (Travel Expense) scenario, what kind of calls will be made to backend and will these be through Connector, or ITS, or WAS?
As per my understanding ITS is used for transactional Iviews.
When will Connector and WAS connections will be used?
Thanks
Davinder

Hello Experts,
1. Connectors - using logon group.
2. User Management with LogonTicket.
3. ITS - pointing to specific application server - Can't we use logon group for ITS traffic going to backend
4. WAS - pointing to specific application server - Can't we use logon group for WAS traffic going to backend
In ESS/MSS (Travel Expense) scenario, what kind of calls will be made to backend and will these be through Connector, or ITS, or WAS?
Regarding points 3 & 4:-
http://help.sap.com/saphelp_nw04/helpdata/en/42/5cfd3b0e59774ee10000000a114084/frameset.htm
You can only use the SAP Message Server for HTTP load distribution, if the browser is the direct client of the message server. If another component lies between the client (browser) and the message server, (for example, the portal), you cannot use the message server to distribute the load.
So this is a requirement to use the webdispatcher if your backend is called from the Portal. Otherwise all requests will go to the CI.
(Q) In ESS/MSS (Travel Expense) scenario, what kind of calls will be made to backend and will these be through Connector, or ITS, or WAS?
(A) It depneds on how you have configured the services. Usually its via HTTP, HTTPS or a SOAP adapter to a FM.
Hope this helps

Broadcasting with Multiple Application Servers

Hi, If I schedule a query broadcast to fill olap cache and I have multiple production servers which App server(s) will get the cache filled? What ever server the broadcast job runs on?
If anyone can give some insight it is greatly appreciated.
Thanks,
Ken Murray

1. If the OLAP cache is set to main memory than the OLAP Cache only gets created on the server in which it is run? So if I have 4 servers with load balancing then it is possible for the next 3 people who run the query to not benefit from the initial OLAP Cache created.
--> Next 3 people will benefit only if they log in to the same server, if cache was created in app server 1 and next 3 login to app server 2, 3 and 4 they wont hit the cache from app server 1.
2. If I change it to BLOB than any of the query runs on any server would access the initial OLAP Cache Entry that was created?
--> Yes.
3. Where is this BLOB Cached created and made available from? The DB Server or on 1 of the APP Servers?
--> DB Server
http://help.sap.com/saphelp_nw04/helpdata/en/00/241da12ef84f40bb6ecd3ae73d8b58/content.htm
4. If SAP can make BLOB Cache available to all servers then why couldn't they make Main Memory Cache available to all servers?
Main memory is specfic to a server like how you have RAM for your PC, this is not accessible by other system. BLOB is Database and can be accessed by multiple systems.
Thanks.

Installing multiple Application Servers using setup

Hi there,
I successfully installed SunONE application Server on my machine. I wish to install a completely new Application Server in a different directory, however using the setup GUI - when I get to the "Select Components" screen, all options are greyed out and I cannot continue.
I have already created a new domain in the original install and deleted the default "domain1" domain, however it seems that there can only be one installation of Appserver 7.0 on a machine.
Is this correct?
If not, how do I install this a second time?
Regards
Brian.

With the full version of the product (non evaluation copy) that installs as root on your unix environment, you can only have one install image. That is not a problem it is designed that way.
You can have as many admin domains as you wish on a server. With the PE version, you can only have one instance per domain. With the SE version this restriction is lifted. You can put those domains anywhere you want and have them owned by any user (as long as asadmin create-domain is run as root)
For assistance you and get help from asadmin:
# ./asadmin help create-domain
User Commands create-domain(1)
NAME
create-domain - creates a domain with the given
name
SYNOPSIS
create-domain [--path domain_path ] [--sysuser
sys_user ] [--passwordfile filename ] --adminport
port_number adminuser admin adminpassword password
domain_name
DESCRIPTION
Use the create-domain command to create a domain
with the specified administration port number,
administration user, administration password, and domain name.
By creating a domain, an administration server is
created in a directory named as the domain name. This
command can be run locally only.
OPTIONS
--path directory path where the domain should be
created. If specified, path must be accessible in the
filesystem. If not specified, the domain is created under
$AS_DOMAINS_PATH directory.
--sysuser owner of the domain directory. Must be
a valid user on the system (Solaris only). The
domain is created under the specified system username.
If not specified, the current username is used.
--passwordfile file containing passwords
appropriate for the command (e.g., administrative instance).
--adminport port of the administrative instance.
The port number cannot be currently active.
--adminuser user name assoicated with the administrative instance.
--adminpassword password associated with the administrative name.
OPERANDS
domain_name name of the domain. Must be a unique name.
EXAMPLES
Using create-domain
asadmin> create-domain --path /u/domain1/domain_root
sysuser user1 adminuser admin --adminpassword
adminadmin --adminport 6868 domain1
created domain domain1 successfully
Where: the domain1 domain is created in the domain_root
directory.
EXIT STATUS
0 command executed successfully
1 error in executing the command

NT startup parmaters for multiple weblogic servers started as a service

I have the need to start multiple weblogic servers, using NT services.
I have created a second folder with a properties file listening on another
port.
I am using the following startup parameter
-J-Dweblogic.system.name=Test
My question, this works when I type the startup parameter, is their anyway
to have this automatically entered
on server startup.
Is their a registry setting to make this permanent
Thanks

The answer is...
- Use a product to turn applications into an NT Service (e.g.
ServiceMill)
- Directly run the Weblogic Server Java class via that application
--> As many WLs on one machine as you like.
Send mail if you need specific details.
Best regards

Conversation: NT startup parmaters for multiple weblogic servers started
as a service
Subject: Re: NT startup parmaters for multiple weblogic servers started
as a service
I wish that was the case.
The problem is, while you enter the startup parameter once, it only
is good for that startup of the weblogic server,
The next time the server reboots and the services start, unless you
re-enter the startup parameter -J-Dweblogic.system.name=Foldername
The weblogic server starts using the wrong properties file.
Is their anyway using NT services to have the correct instance of WL
to start everytime.
I have checked this newsgroup and this question has been posted
before, but so far no one seems to have the answer.
I know in a production eniviorment someone must be running more that
one instance of a WL server as a service, Hopefully their is an
answer on how this is done.
Thank you
