Application Server Memory Requirements from 4.6C to ECC 6.0

The projected physical memory increase for the Application servers from 46C to ECC6 appears to between 45% - 66%. This is based on the delta notes 517085, 752532, 778774 and 901070. It also appears from a presentation from Christian Oehler called "Transition and Upgrade to SAP ERP" to be the case.
I cannot find anything in the above referenced SAP notes that indicates where this additional memory is consumed, so I'm concerned SAP is factoring in new functionality and/or JAVA stack in this. Furthermore we have upgraded our HR system from 46C to ECC6 sometime ago and included JAVA and saw around a 20% memory increase.
We are doing a strictly technical upgrade and are not turning on new functionality at this point (no JAVA stack), we are also not increasing user population. Our Test Systems, which have production data volumes do not reflect any growth in this area, but we are not stressing it with user load.
Does anyone have an idea of what we could/should see given the nature of our upgrade? We are preparing for a 25% increase in App server memory, but not for 50% plus. We are not doing a sizing exercise since this is just a technical upgrade and the GLFU service has yet to start.
If anyone has any insight into what should be expected or what they have seen for memory requirements from 4.6C to ECC 6.0 Application Server sit would be greatly appreciated.
Thanks

Hi Mark,
More memory is required because ECC 6.0 is much more huge system than 4.6C. If you are planning to increase server memory by 25% only, than you can see performance problems if system will be heavyly used. But it depends mainly on number of WP and active users. 25-50% more memory is required if you are not installing J2EE addin afterwards. If you are planning to convert the database to Unicode, than you will need an additional memory....
It's not easy to say 25% will be enought or 50% is required, but I would suggest to go to 50% at least.

How to make upgrade from application server and not from central instance?

Hello SAP Gurus!
I have SAP ECC release 6.0, and I´m gonna make upgrade to enhancement package 6.06, do you know if Can I make upgrade from application server, but not from central instance?
Thanks.

Hi Victor,
Upgrade process has to execute from the server where message server is running.
So I guess it is not possible to initiate the SAP upgrade from application server.

Create XML file on application server (unix directory) from internal table

Hallo everybody,
I have got the following problem:
I am working with <u><b>release 4.6C</b></u> and have got to create XML files from HR master data and organizational data respectively.
This takes place in 3 steps:
1.     Collect the data in an internal table
2.     Convert the data to XML format using the function module 'SAP_CONVERT_TO_XML_FORMAT'
3.     Download the data
If I download the converted data, which are in an internal table, to the presentation server via the function module WS_DOWNLOAD and open it with the Internet Explorer, everything is ok.
If I download the converted data to the application server, i.e. into a unix directory via
open dataset, loop at internal table, transfer working area to file, close dataset
and then try to open it, this is not possible, because after the last tag some unreadable characters, e.g. a square, appear that arent supposed to be there. Thats what my colleagues told me, for I havent got access to the server.
I have no idea where these characters come from and how I can get rid of them. I guess that either I have to modify (how?) the table with the converted data before the download or I have to use another way to convert the data. For the second way I would probably have to work with an XML class or an XML interface. Unfortunately II am not an expert in working with classes so sample coding would have to be rather detailed.
Heres some more information about how I work with the conversion function module:
call function 'SAP_CONVERT_TO_XML_FORMAT'
       exporting
            i_field_seperator    = lv_field_seperator
           i_line_header        = lv_line_header
           i_filename           = lv_xml_file
           i_appl_keep          = ' '
            i_xml_doc_name       = lv_xml_doc_name
       importing
            pe_bin_filesize      = lv_result
       tables
            i_tab_sap_data       = gt_data
       changing
            i_tab_converted_data = lt_tab_converted_data
       exceptions
            conversion_failed    = 1
            others               = 2.
lv_field_seperator = X.
lv_xml_doc_name = Personalstammdaten Publikation
lv_result: type i
gt_data: fields: PERNR, PERSG, PERSK etc.
types:
begin of truxs_xml_line,
    data(256) type x,
end of truxs_xml_line.
types:
truxs_xml_table type table of truxs_xml_line.
data:
lv_tab_converted_data type truxs_xml_line,
lt_tab_converted_data type truxs_xml_table
open dataset lv_xml_file for output in binary mode.
loop at lt_tab_converted_data into lv_tab_converted_data.
transfer lv_tab_converted_data to lv_xml_file.
endloop.
close dataset lv_xml_file
lv_xml_file: /usr/users/.../.../Personendaten_2004-11-02.xml
Hope the information is detailed enough! Otherwise let me know. Thank you in advance.

Hi Raja,
tried the "TEXT" mode, but that didn't help.
There are still characters after the last tag, that are not supposed to be there including a date that is not
the creation date of the file.
Thank you for your help.

Create application server moves files from i drive to c drive?

Hello,
my set up:
windows 2003
sql server 2008
peopletools 8.51
application FMSC 9.1
PS Home on I:\TFS91
While setting up a demo system for FMSC 9.1, I noticed that the application server and process schedulers are being created on the C: drive.
This is strange because the PS Home are on the I: drive.
I start PSADMIN from the I drive, but every time I create an application server on the I drive it copies the application server to the C: drive.
Why is this happening?

JNDI on a Sun Application Server 9.0 from a Java SE Client

Where do I go to find a listing of property pairs I have to set to allow my Java SE application to make use of JNDI (to find Session and Entity beans)?
This is my approach from what I have read so far:
      Context context;
      Properties properties = new Properties();
        // Assign configuration properties here.
        try {
            context = new InitialContext(properties);
        } catch (NamingException ex) {
            ex.printStackTrace();
        // Put code here to start getting references to JNDI stuff....
        // ...and other neat Java EE things. :)If anyone in-the-know can help steer me a little on this, I'd be very grateful!
My current setup is just a netbeans development environment. I'm using the included application server.

I receive an exception in the J2SE client when trying to do lookups.
I have created a simple test of a bean and a JMS Queue
package ent1;
@Remote
public interface HelloWorld {
public String sayHello();
public void sendQueueMessage(String message);
package ent1;
@Stateless
public class HelloWorldBean implements HelloWorld {
@Resource(mappedName="jms/QueueFactory")
private QueueConnectionFactory m_QueueFactory;
@Resource(mappedName="jms/myQueue")
private Queue m_Queue;
private static final Logger logger = Logger.getLogger("ent1.HelloWorldBean");
public HelloWorldBean() {
public String sayHello() {
    return "Hello From "+this.getClass().toString()+"!";
public void sendQueueMessage(String message) {
    Connection conn;
    Session session;
    MessageProducer producer;
    TextMessage msg;
    try{
      conn=m_QueueFactory.createQueueConnection();
      session=conn.createSession(false,Session.AUTO_ACKNOWLEDGE);
      producer=session.createProducer(m_Queue);
      msg=session.createTextMessage(message);
      producer.send(msg);
    }catch(JMSException e){
      logger.log(Level.SEVERE,e.getMessage(),e);
      return;
    logger.log(Level.INFO,"Message '"+message+"' sent");
}And I can connect to the bean and Queue from an enterprise application with resource injection.
But when I try to lookup the bean or JMS QueueConnectionFactory from an J2SE client..
    InitialContext ic;
    HelloWorld hello;
    Hashtable<String, String> env = new Hashtable<String, String>();
    env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
    env.put("java.naming.provider.url", "iiop://localhost:3700");
    try{
      ic=new InitialContext(env);
      hello=(HelloWorld)ic.lookup("ent1.HelloWorld");
    }catch(NamingException ne){
    }or
    javax.jms.ConnectionFactory connectionFactory;
    try{
      ic=new InitialContext(env);
      connectionFactory=(javax.jms.ConnectionFactory)ic.lookup("jms/ConnectionFactory");
    }catch(NamingException ne){
    }I get an exception

Problems in starting up Application Server Control from SOA Suite

I have an issue starting up the Application Server Control page from the SOA Suite (10.1.3.1.0) welcome page. I can open all other control pages by entering the oc4jadmin/<password> where <password> is the password specified at the time of installing (Standard Install) the SOA suite.
Application Server Control accepts the oc4jadmin/<password>, but shows another page to "Supply Administration Credentials". The following error message is shown on the page.
+++++++++
This OC4J is configured to make JMX connections via RMIS and fall back to RMI if the RMIS port is not configured. The RMIS connection on the OC4J instance home on Application Server shara.SHARA_HP is configured but a connection could not be established. The JMX protocol is specified by the oracle.oc4j.jmx.internal.connection.protocol property in opmn.xml
You are logged in as oc4jadmin.
Enter the credentials for a cluster-wide user in the oc4j-administrators group. These credentials are needed by Application Server Control to make remote connections.
* User Name
* Password

Has any one encountered this? Any clues where to look for things? Initially I had the problem with all the controls due to my computer name as it has an underscore ie., SHARA_HP. I had to use localhost to overcome this ie., http://localhost:8888/em
Any help/clue would be appreciated.
Thanks

At install time there is a question that asked if you would like to configure adminstration now. (Something like that). By default this is not checked. If you did not check it you cannot access enterprise manager.
The is probably a way to configure it, but it might be faster reinstalling.
There is a simple way to de install by going to the ORACLE_HOME/bin and run the deinstall script.

Why it take so long to start the SAP Web Application Server?

As I read from the doc that starting the SAP Web Application Server will take from 25 to 40 minutes, I don't believe. But as I try it on my machine, it does take really so long. Isn't it a wonder?
I am used to work with Tomcat, JBoss, BEA etc. None of them will take so long.

Hi Chen,
In a WAS I assume that it has dual stack (ABAP + JAVA)
For the startup of a ABAP Stack it generally takes about 2 minutes or so.
And for the WAS JAVA STACK should take around 8 to 15 minutes depending on the application, services and hardware sizing.
The reason for the long time required for a WAS Java Stackis:
JAVA Stack depends on three diffrent components: a) dispatcher(java) b)SDM c) Server0 process.
Now before the execution of all these the first thing what happens is the initializastion of jcontrol which inturn initiates the java bootstrap process.
At this moment of time the JVM environment takes some time for the loading and memory management. Once the JVM is loaded successfully then only the three compnents (SDM, dispatcher and server0) are initiated to run.
The SDM and dispatcher do started up with a couple of services and hence require not toomuch of time.
But the main component i.e Server0 process consumes a lot of time to startup at it requires many of the Java stack services to start before it reaches running state.
Again the port configuration for HTTP for SDM , dispatcher , server0 and java process also takes place.
So this was an overview for the Time required for a WAS Stack to come up in operational condition.
Apart from this , seeing specifically to your scenario, wherein it takes 25 - 40 minutes could be an issue with the Hardaware sizing of the Server and the Sofware compnents / tools loaded. We might need to analyze it in more detail to get a clear picture.
I hope this helps you!

Prem

SAP ERP 2005 ECC 6.0 with Windows 2000 Application Server

Hi,
We are currently running SAP 4.6C in iSeries model 570 OS V5R3.
I would like to know after upgrade from 4.6C to ERP 2005 ECC 6.0 if we will gain any performance improvement by adding Windows 2000 Application Servers in our environment. Second Question - how much load will be taking away from the iSeries if adding one application server (Memory and CPU).
Ramon

Hi Ramon,
what hardware do you use at the moment ?
820, 870, 5xx ?
How any CPUs ?
How much memory ?
You are on 4.6C ASCII right now ?
In your case, I don't see, that Win 2003 servers help in performance, I would guess, that the CPU after the upgrade is about 60% which is still ok - then using 3-tier - especially in R3 environments is mostly not good for the performance because of the DB time increasement.
The memory you will need is pretty the same for the iSeries.

Hi
I think some basis related configuartions to be done
Try like this and inform me
A cyclic job runs, which processes the messages seen in the SOST queue.
Are you sure it's not the frequency of the cyclic job, rather than the
number of messages in the queue, that you are observing? In messages
that are queued and before the cyclic job runs, "wait for comm. service"
is the normal status.
If you mean that there are always 4 items queued in SOST regardless of
the cyclic send job, then I have no ideas. I would have thought there
was no way to do that.
when the send job runs it just never
picks them up & sends them, while it picks up many others. The send job
is somehow blind to these; no error message occurs. In this case, I
'delete' them from the queue (in SOST) and then 'undelete' (drop down
menu -> /Go to /Deleted Items) them and then re-queue them. THEN they
actually get picked up & sent when the next cyclic send job executes.
Regards
Pavan

Client/server vs. Application Server

Our company has around 30 sites with each one having its own Oracle database server and file server (repository for executables of Forms6i/Reports6i). All the sites have the same applications running, i.e., the same set of programs are replicated to each site. At present we are running the applications in client/server mode (Forms6i/Reports6i runtime is installed on each client machine).
We are also using some third party modules developed in VB/VC++.
Now we are looking for the Centralized Solution, i.e., We want to have a Single Database Server available to all the sites all the sites are already linked with Network Leased lines).
Now we want to know the impact of running centralized file server (located at Corporate Office site) accessible from all the sites (through same client/server mode).
Will this solution work for us or we should move to 3-tier mode? Please suggest us the best feasible solution which can be implemented as early as possible.
What I mean to ask in the question above is: if a good intranet connectivity is available among sites, what would be the better approach, client/server or n-tier?
What actually would we gain by using application server in this context? Does the Data travelling is reduced from Database Server through to the Client Node in 3-tier AS approach? Does this 3-tier approach will reduce the Burden on Leased Lines? Does we gain more network resources available in 3-tier?
What I think is that in client/server mode, the data is travelled from Database Server to Client Machine, but using Application Server, the Data from Database Server will travel upto Application Server and NOT to the Cleint machine (on browser etc.), hence reducing Network Load.
Please clarify as your input makes a valuable role in our decision-making.

Hello,
I'll take a stab at this one...
If you have enough network bandwidth, you should be fine funning in client/server mode. I have worked with clients with this same configuration. In addition to having a centralized DB, we have also centralized the forms on a network drive allowing users to access the same files and removing the need for users having to update their files locally. The biggest problem I see with this configuration, as long as you have enough band width, is that your configuration is not supported as 6i has been desupported.
From my perspective you really don't have any choice but to upgrade your application so that you can be supported. The good news is that for the clients we have worked with upgrades have gone very smoothly. In fact recently we have started to partner with another vendor that has a tool specifically designed to upgrade Oracle Forms and it includes additional features above and beyond what you get from Oracle. This tool has drastically reduced the amount of time to complete upgrades (like going from a 2 year project to just a few weeks).
I hate to answer this question because it is hard to answer without really getting into the details with you. The good news is once you do have a centralized DB and centralized application maintenance will be significantly easier.
One last option you might consider that our company has done is to use Citrix. I've never used it for Oracle Forms, but for other client/server applications it has allowed out clients to web enabled their existing applications without changing them at all and also get a boost in performance. I wouldn't recommend this approach to you because what you have should be short term until you get your forms/reports upgraded.
If you have any specific questions I can try and answer them for you. Good luck and let me know if I can be of any assistance.

JMS & Application Server

hi,

VJThanks for your answer. It doesn't help me very much.
I find always over ejb but never jms. I need to connect to application server to get the connection factory.
thanks for your help.

Migrating applciation from weblogic to oracle 9i application server(OC4J)??????

Hi,
I am migrating my ejb application from weblogic to oracle 9i application server.What changes are needed to be made in code and what configuration changes are required.
In my application i use a couple of session beans wherin a session bean calls the method of the other session bean which acceses the database.I am using a jdbc thin driver for the database connection. is it possible for a session bean to call a method of another session bean which access the database??This concept works well in weblogic where the current application is running.
The problem is that while migrating the application to the orion server, it gives an OrionCMTException ...
memory leak..etc.
Could any one clarify.
Thanks in advance!!!

Hi Avi and Harrison,
Cease Fire avi!!!!.First of all let me clear the issue of posting the same problem twice.Well, when i mentioned the problem the first time , i found the title session bean deployment was not right and few people would look into it as it was a common problem so i thought it would be appropriate if i mentioned the title correctly , so i posted the query again with the change in title.
Now coming to the answer for ur questions.
The platform used is MS Windows NT.
The (OC4J) version is 1.0.2.2.1.
I am not using JDeveloper.
The database is oracle 8i and i am using the thin driver.
The beans to be deployed are stateless session beans.
The client involved is a web client i.e a jsp application.
The first session bean is as follows.

But if the DBUTILITY session bean is changed to a simple bean and accessed the code works fine and i am able to retrieve the data.Is the problem there because u one session bean cannot access a database connection method from another one or could it be because of the driver???
I hope i am clear.Please revert back in case any more references are needed.
Thanks in advance!!!!!!
