Multiple server sessions

Hi,
Should there be any issue mixing objects between multiple server sessions.
We have multiple services that each have each have their own ServerSession.
There are situations where objects retrieved through one ServerSession are ultimately part of an object that is persisted through another ServerSession.
Note: communication between client and services is via RMI and persistence is performed using the mergeWithReferences method.
Example,
- Person object has an Address object.
- Address is retrieved from ServerSession 1 (RMI)
- Person object is retrieved from ServerSession 2 (RMI)
- Address is added to Person and Person is persisted
thru ServerSession 2. (RMI)
The behavior I've observed is inconsistent but ultimately there seems to be problems.
From the example above, occasionally ServerSession2 will attempt to reinsert the Address object into the table.
In the case where Address is read only the cached version of Person in ServerSession2 will have a null Address attribute after persistence even though the database was updated correctly.
What accounts for this behavior?
Thanks
Mark

Marc,
The problem you are seing is related to TopLink's existence checking. When you go to write an object from session 1 into session2 and it does not exist in the cache TopLink assumes the object is new. This is very similar to when you are running in a cluster and your write request ends up in a JVM where the TopLink session has not read in the object you plan to write.
In order to make this work you can change the existence-checking setting, which I don't recommend, or you can alter your pattern for dealing with the UnitOfWork.
When you serialize the object(s) across RMI to the server that is going to do your writing I recommend the following pattern:
1. Acquire UnitOfWork from session
2. Read objects from database
unitOfWork.read(person);
unitOfWork.read(address);
3. Merge objects (unitOfWork merge APIs)
4. Commit UnitOfWork
Step #2 is important here. If you are writing to a session that has the objects cached then no database call is required. If not, the database version will be read in. The merge will copy the values over to the working copy and the commit will calculate and write any necessary changes.
Other recent threads in this forum and the documentation detail the merge options.

Similar to multiple x sessions

I know that on linux you can initiate multiple x sessions so that when you connect to the computer using VNC and use the mouse and keyboard without interfering with what the user on the computer does.
Is there some way to start a new session on the mac and do that same thing?

TL;DR version - not really.
Long winded version...
Much of the apple magic in making X11 work within the Cocoa on top of Aqua on top of Quartz/OpenGL/QuickTime stack makes this really hard to do.
Have you looked over Xnest - it's really powerful and can act as a server and a client. If remote boxes are ssh into the mac and using the multiple displays set up under Xnest your local display would be cluttered but one mac could support many remote machines with X11 services.
See these links for some good reading on the subject:
[Fun with Xnest HowTo|http://box.matto.nl/xnest.html]
[X11 for Mac OS X|http://www.scl.utah.edu/computers/mac/help/x11>
The only time I've seen this actually deployed, xnest was ditched after a few days of pain. Instead, a beefy Mac Pro with RAM/CPU to spare was set up with VMWare fusion and a virtual machine per user with linux/freeBSD installed. Then X11 could roam there free of "the dictator" known as Quartz Compositor.

JNDI Lookup for multiple server instances with multiple cluster nodes

Hi Experts,
I need help with retreiving log files for multiple server instances with multiple cluster nodes. The system is Netweaver 7.01.
There are 3 server instances all instances with 3 cluster nodes.
There are EJB session beans deployed on them to retreive the log information for each server node.
In the session bean there is a method:
public List getServers() {
List servers = new ArrayList();
ClassLoader saveLoader = Thread.currentThread().getContextClassLoader();
try {
   Properties prop = new Properties();
   prop.setProperty(Context.INITIAL_CONTEXT_FACTORY, "com.sap.engine.services.jndi.InitialContextFactoryImpl");
   prop.put(Context.SECURITY_AUTHENTICATION, "none");
   Thread.currentThread().setContextClassLoader((com.sap.engine.services.adminadapter.interfaces.RemoteAdminInterface.class).getClassLoader());
   InitialContext mInitialContext = new InitialContext(prop);
   RemoteAdminInterface rai = (RemoteAdminInterface) mInitialContext.lookup("adminadapter");
   ClusterAdministrator cadm = rai.getClusterAdministrator();
   ConvenienceEngineAdministrator cea = rai.getConvenienceEngineAdministrator();
   int nodeId[] = cea.getClusterNodeIds();
   int dispatcherId = 0;
   String dispatcherIP = null;
   String p4Port = null;
   for (int i = 0; i < nodeId.length; i++) {
    if (cea.getClusterNodeType(nodeId[i]) != 1)
     continue;
    Properties dispatcherProp = cadm.getNodeInfo(nodeId[i]);
    dispatcherIP = dispatcherProp.getProperty("Host", "localhost");
    p4Port = cea.getServiceProperty(nodeId[i], "p4", "port");
    String[] loc = new String[3];
    loc[0] = dispatcherIP;
    loc[1] = p4Port;
    loc[2] = null;
    servers.add(loc);
   mInitialContext.close();
} catch (NamingException e) {
} catch (RemoteException e) {
} finally {
   Thread.currentThread().setContextClassLoader(saveLoader);
return servers;
and the retreived server information used here in another class:
public void run() {
ReadLogsSession readLogsSession;

The application is working for multiple server instances with a single cluster node but not working for multiple cusltered environment.
Anybody knows what should be changed to handle more cluster nodes?
Thanks,
Gergely

Thanks for the response.
I was afraid that it would be something like that although
was hoping for
something closer to the application pools we use with IIS to
isolate sites
and limit the impact one badly behaving one can have on
another.

JPA Project, TopLink Server session and ClassLoader issue

hi,
I'm working on the project where JPA annotations are used to describe the mapping between POJOs and the database tables. JpaHelper class is used to bridge the gap between toplink-essentials and toplink. The EntityManagerFactory and the oracle.toplink.threetier.Server are obtained as following:
emf = JpaHelper.getEntityManagerFactory(Persistence.createEntityManagerFactory("myUnit"));
server = JpaHelper.getServerSession(emf);
Due to different functional and architectural constraints the same Server session has to be shared across different web applications. Thus the EntityManagerFactory has been bound to Weblogic JNDI tree and used by web applications to obtain Server session. It works very well for the very first client that is trying to query the data, but due to the fact that in the web container different web applications are using different ClassLoaders the QueryException “Missing descriptor for [class ...]” is being thrown for all consecutive call from other web applications. The same behaviour is observer after re-deploying the “first” application.
Going throughout different threads in the forum I learned that it could be solved for the "pure TopLink" projects where “sessions.xml” is used as following:
oracle.toplink.internal.helper.ConversionManager.getDefaultManager().setShouldUseClassLoaderFromCurrentThread(true);
boolean shouldLoginSession = true;
boolean shouldRefreshSession = true;
boolean shouldCheckClassloader = true;
session = SessionManager.getManager().getSession(new XMLSessionConfigLoader(), "mySession",
Thread.currentThread().getContextClassLoader(), false, true, true);
Could you please let me know if there is something similar for JPA projects where “sessions.xml” isn’t used or other options have to be considered?
regards,

I am not completely sure I understand what product and version you are using. TopLink Essentials and Oracle TopLink are independent products. They share the same heritage and much of the same functionality but typically you would only use one of them in an application.
If you have multiple web applications (WAR) that need to share the same JPA persistence unit I would package all of the JPA classes in their own JAR file and co-locate all of these WARs with the persistence JAR in a single EAR file. This should give you the capability to share the classes across the web applications.

Multiple j-sessions for IOP fail-over?

Weblogic has the ability to support multiple j-sessions to allow fail-over of the connection.
My understanding is that this is not currently supported in IOP.
When will IOP support multiple j-sessions?
Is it possible to get a patch for this in the current version 11 of IOP?
Thank you.

That is part of the product roadmap to support multiple j-sessions for IOP fail over using Weblogic. That way, if the primary IOP server fails, the user can be re-routed to the backup server in a high-availability fashion. However, that is not supported currently, but will be over the next couple of releases.

How Can i specify multiple server names in rwservlet.properties file?

How Can i specify multiple server names in rwservlet.properties file without clustering?
I am using oracle 10g Application server. we have 3 servers Repsvr1, RepSvr2 and RepSvr3. Now i need to configure rwservlet.properties file to point to these servers based on any running report. i got 3 keymap files with reports info.
Sample entry in the key map file is:
key1: server=Repsvr1 userid=xxx/yyy@dbname report=D:\Web\path1\path2\reports\Report1.rdf destype=cache desformat=PDF %*
key2: server=Repsvr2 userid=xxx/yyy@dbname report=D:\Web\path1\path3\reports\Report2.rdf destype=cache desformat=PDF %*
rwservlet.properties file letting me to enter only one servername. Even though i merged all 3 keymap files into 1, still i have the server name issue. If i leave the server to the default name still i am getting the below error.
REP-51002: Bind to Reports Server Repsvr1 failed. However, i know the default rep_<servername> would be used incase we dont have SERVER=<value> parameter in the rwservlet.properties file.
If i specify the servername in the rwservlet.properties file then only Repsvr1 reports are working fine and other 2 server reports are giving the same error like
REP-51002: Bind to Reports Server <<Server Name>> failed.
how can i configure the info which will work all 3 reports. 2 Port servers are invoking using oracle forms and report server is invoking using ASP pages.
If i specify Server name & Key map file in rwservlet.properties one at a time, all the reports are working without any error, whenever i am trying to integrate all 3 to workable i am getting binding error. if i exclude the server from rwservlet.properties still i am getting the same error.

My RELOAD_KEYMAP setting is YES only.As i said If i specify Server name & Key map file in rwservlet.properties one at a time, all the reports are working without any error.
keymap file entries
key1: server=Repsvr1 userid=xxx/yyy@dbname report=D:\Web\path1\path2\reports\Report1.rdf destype=cache desformat=PDF %*
key2: server=Repsvr2 userid=xxx/yyy@dbname report=D:\Web\path1\path3\reports\Report2.rdf destype=cache desformat=PDF %*
If i use http://server.domain:port/reports/rwservlet? cmdkey = key1 should bring the report from Repsvr1 and http://server.domain:port/reports/rwservlet? cmdkey = key2 should bring the report from Repsvr2, but i am getting an error from Repsvr2 saying that REP-51002: Bind to Reports Server repsvr2 failed.
Only Servername Repsvr1 is in rwservlet.properties file. Now what is the best option to by pass the server from rwservlet.properties file and should be from keymap file. if i comment server name in rwservlet.properties file still i am getting REP-51002: Bind to Reports Server <<Server Name>> failed error for both keys.

Load Data from a table on one server's database, to the same table structure in multiple server databases

Hi,
I have a situation where i have to load data from one server/database table to multiple servers/databases.
Example:
I need to load data from dbo.TABLE_A (on Server: Server_A & Database: Database_A) to the same table on the list of server databases like
Server: Server_B , Database: Database_B
Server: Server_C , Database: Database_C
Server: Server_D , Database: Database_D
Server: Server_E , Database: Database_E
Server: Server_F , Database: Database_F
Server: Server_G , Database: Database_G
Server: Server_H , Database: Database_H
so on and so forth on 250 such server database combinations.
The table structure is the same on all the servers.
If i make the source or destination dynamic, it throws an error while mapping ?
I cannot get Linked server permissions and SQL Server Config thing doesn't work as well.
Please suggest on how to load data from one source to multiple server/databases.
Thank you.

I just need to transfer one table's data. its like i have to use a query to pick data for
the most recent data. So i use something like, select A, B, C, D from dbo.table where ETL_TIMESTAMP > (the max(etltimestamp) in the destination on different server). There are no foreign key relationships and the data should not be truncated. it just had
to append the new records.

Application Server Session timed out (-11) (lack of debug in internal ITS)

Dear Sirs,
I get the error message below, when I try to run a IAC through internal ITS. The IAC worked for a while (<30 minutes), and then suddenly this error appeared.
I can see that this error message has been asked about previously, but then in connection with statefull/stateless BSP applications (e.g "Session timed out thread", on this forum May 31 2005).
In this thread the solution is apparently to alter the 'rdisp/plugin_auto_logout', is this the case for us as well?
I have read Error handling using the ICM , but not able to actually beeing able to pinpoint the problme.
All our other IAC are working it is only a problem with one of them. The problem is still valid even if I log on with different user, and the error is still there now even after two hours. The problem transaction is a altered version of the WSTA, and I am able to get the first screen where I enter the store number.
Any tips or suggestions to pinpoint the error?

Dear Sirs,
The error has been solved. It was a matter of an illegal input sendt to the RetailHeaderFunction.
However, this makes way for another question.
On the standalone ITS, it was possible to get error messages which indicated where the code contained errors, when it was runned.
How is it possible to make the internal ITS gives better feedback (errors?), and show where the error is?

[solved] who command doesn't show X server session

Alright. The point is, what do I need to do in order that who shows my X session?
I tried export DISPLAY=:0 but this doesn't add :0 to the who command listing.
The reason I am asking is that I want to use the following dispatcher script which queries for :0, assuming that who shows the display variable.

Does GRC AC 5.2 supports multiple server nodes

Hello Experts,
Does GRC AC 5.2 is supported with multiple server nodes.
Thanks
Davinder

Thanks once again Harleen,
For AC 5.2 i will raise an SAP OSS message and share the results with community.
For AC 5.3, we have configured SAP logger and make neccesary changes in NWA. But log information over here is not as detailed (background job information is missing) as we get in RAR -> Background Jobs ->View Logs.
I have generated another thread for this issue (GRC AC 5.3 Logging strategy in multi server nodes), would appreciate if you can show some light on this issue
Thanks

Multiple View sessions, same PC?

View 6.0.1, Client 3.3.0
Can I have multiple View sessions from the same PC? In other words
Launch the Horizon View client, login, and access a desktop
Launch the Horizon View client again, login as a different user, and access a different desktop
Repeat until I have many session open at once
The reason I ask is we are migrating from Exchange to Gmail. Google provides a utility called GAMME that in a larger environment can be run from multiple machines with each machine migrating one portion of the alphabet. Rather than using 10 physical machines I would rather use 10 View desktops. This will work slick if from my real PC I can access all 10 view desktops. I will be using a different login account to access each desktop.

Have not tried yet. I did not want to go through the time setting up a separate non-persistent desktop pool if I could not login to more than one desktop at the same time. Now that I know it will work, I will run with it. Thanks for the help

Multiple user sessions for ADF application

Hi All,
We have a ADF application with 3-4 pages starting with a login screen.
Assume we have two users, user1 and user2. In same system but different browser windows, when both users are logging in, only user2 's session is active. Though user1 logged in first and is able to perform transactions, the moment user2 logs in, user1's session is being over-written by user2 (user1's window now displays user2's information). I have observed the URL of user1 window which now changes to user2's URL (_adf.ctrl-state parameter of user2 is displayed in user1 browser)
How do we overcome this?? We have a requirement to be able to open multiple user sessions.
We are using JDeveloper 11.1.2.3.0 and browsers being used are IE 8, IE9 and chrome.
Thanks,
Deepti

Hi,
Continuation to my above question
I am using these two statements in my code..
ExternalContext ectx = FacesContext.getCurrentInstance().getExternalContext();
HttpSession httpSession = (HttpSession)ectx.getSession(true);
On any event in Window1, I gues it is getting the context and session of window2(this being the latest)..
Shouldnt it return the context and session of the current window instead of the latest window???
This problem is well explained here
internet explorer 8 - How to avoid session sharing provided by IE8 programmatically in Java EE application? - Stack Over…
I want to know.. what is the best way to handle this in ADF... We are using managed beans with request scope and using HttpSession to store few values like user Id.

Hello,
ORA-01194: file 1 needs more recovery to be consistent
ORA-01110: data file 1: '/u01/app/oracle/product/10.2.0/oradata/db/system01.dbf'The system01.dbf which belongs to the Tablespace SYSTEM is still inconsistent.
So, I think you'll need to start from a Backup and apply all the Archived Redo logs before the ORA-600 occured.
More over, try to open a Service Request to My Oracle Support and, send them all the Traces Files and Alert Log so that they can follow all the actions which has occured on this Database. You may need their help.
Best regards,
Jean-Valentin
