Open LMS Session from client host

Dear all,
i have a LMS application installed on a server X, the campus manager version is 3.2.
the application version is pretty old, but it is just working fine.
LMS is opening normally from the server itself.
My problem is that if i try to open Campus Manager/Topology services from a host different than the server itself a java screen opens mentioning trying to connect to ani server, and it just freeze and do not proceed. if i reopen from the server itself it works fine.
the server and the client host are on the same vlan, so no network access limitation exists.
Note: When i open the http request on LMS server from the client side, i authenticate and enter to the app normally but if i try to open the topology services or path analysis it do not proceed.
While checking the logs i found that it is like denying the Client Host name or IP Address.
please find log attached.

Dear Afroj,
Concerning the above mentioned debug steps; i don't find the option in the sequence on my server.
Point 1)      I can find LMSHomeScreen --> ServerConfiguration --> Setup --> ANI ServerAdmin --> DebuggingOptions
Point 2) & 3) I Select "Enable tracing on the selected modules". From the drop down list i check the "Trace enable" check box for the Module "topo".
       On the same page down, i check the "Record trace messages in log file", i enter the name and the path for the log file, C:\ANI_Debug
       And i press apply,
Point 4) & 5) From here i am not able to continue, there is no button to start debug nor under LMSHomeScreen --> ServerConfiguration --> Setup --> ANI Server        Admin --> Debugging Options nor under LMSHomeScreen --> Campus Manager --> Topology Services
There no path Campus Manager --> Admin
Point 6) How to run a new data collection?!
Point 7) if i enable "debugging" of java from control panel and i select to "show" java console, how to view Java Logs?
Thank you for your help

How call session bean from Client side

Hi
calling session bean from client side it gives Lookup erroe, it gives JNDI error
how we know session bean is working. in Admin tree bean statis is reb Flaf, and ID is "Down" how we activate it..
null

If you can make a connection using sess_sh, then you know that you have configured your database and listener properly. If it is not working, read the manuals that you can download from technet. They are pretty good, and if you follow the directions, you should see success.
Good Luck!

Restrict concurrent user and/or session from a client

Hi All:
We have an application with database Oracle 10g.
I want to add a new validation to restrict concurrent user and/or session from a client. (we have almost 60 client firms using the software to enter daily trasnactions).
All users from all clients are connecting to the database using a common functional ID.
What I did was:
1) Add a column 'user_logged_in' in the master table for client and update it as Y when user from that client logged on to the system,
2) Insert the application logon details (we can figure out the client details from this) into a global temp table,
3) Create a logoff trigger to update the 'user_logged_in'flag in client master table by using values from global temp table when session logged off and
4) Restrict the users from same client if the flag is 'Y'
But the problem in this case is logoff trigger will not be executed in case if the session got killed or terminated abnormally.
Is there any other good solution for this scenario?
Thanks
Robin

A better question might be - is there any other 'worse' solution than that?

Meaning - if that session goes down you have NO logon details since the data isn't persistent. Is that really useful?
There is nothing you can do to account for someone just pulling the plug on: the server, the network connection, the bridge, the router, etc. And if a user is connected, starts a long-running process and then gets disconnected the process is likely to keep running in the background until Oracle needs to talk to the user again and then realizes that they are gone.
Meanwhile the user is trying to logon again but can't because the system thinks they are already logged on.

Doesn't that kind of make it harder, not easier, to track who is really connecting and using your application?

Fetch Value from Client Session

Hi,
I have a requirement where Vendor code is getting set in the session from a Hidden iView on Portal. Now, my Web Dynpro application has to extract the vendor code value present in the session. I have read few threads and tried by using different code :
1) HttpSession session = ((IWebContextAdapter)WDWebContextAdapter.getWebContextAdapter()).getHttpServletRequest().getSession();
String abc = (String)session.getAttribute("VendorCode");
2) IWDProtocolAdapter protocolAdapter = WDProtocolAdapter.getProtocolAdapter();
IWDRequest request = protocolAdapter.getRequestObject();
String paramValue = request.getParameter("VendorCode");
3) WDScopeUtil.get(WDScopeType.CLIENTSESSION_SCOPE,"VendorCode")
None of the code seems to work. All return a null value. Is there any way I can check when the Session contains the attribute Vendor Code itself or how I can get the Value.
Can I fetch the same by creating a custom portal development where in I can have the Web Dynpro application running in an iView or is there any other way to extract the session attribute itself?
Please reply,
Points will be awarded.

hi,
ulimit command- Limit user resources
su - oracle
ulimit -n (this command will show you the current value for ulimit the default value is 1024)
to increase its value:---
ulimit -n <some value> ( this command will change value for current session only)
example
ulimit -n 101062
once done check the value as:--
ulimit -n( for verification)
search in google for more explanation or revert back to me for any suggestions.... :)

All the computers are connected in LAN
So how to upload a file from client's machine to server's machine

I have a similar chat application. When the user attempts to connect, instead of sending a simple string, the client sends a serialized object(xml string) with all relevant login and session information, this includes the user's IP address. Once the server
receives said information, depending on the type of TCP broadcast (a custom enumerated type) information from one user may be passed to a single user, or distributed to many users.
If it helps, here is the TCPBroadcast object I use. But in order for your server to understand it, you kind of have to build your server and client somewhat around it.

Each app server provides their own jndi factory class. For ex for weblogic it is weblogic.jndi.WLInitialContextFactory. SInce you are using sun app server, check if there are any examples to find out or the docs.
private static String url="http://localhost:4848
Since the client is in a different machine the localhost is not going to work here. provide the url or the machine name of the system in which ur sunapp server is running. In addition u will need to have the stubs of the remote interfaces in ur client machine.

Query takes more time from client

I have a select query (which refers to views and calls a function), which fetches results in 2 secs when >executed from database. But takes more than 10 mins from the client.You are providing proof for the latter part of your statement above.
But not for the former part (fetches in 2 secs when exec'd from db).
It would have been nice if you also provide the sql-trace information for that.
Without it we cannot help you much. Other than making the observation that you obviously have a query that is I/O bound, and that I/O on your system is rather slow: on average an I/O takes 0.04 seconds (66.77 divided by 1663).

How to retrieve DN from client certificate in servlet

Hello,
My servlet has to use SSL, and authenticate users based on the owner of a client certificate.
Is there a way for my servlet to obtain the session's client certificate and extract the owner's DN from it?
Thanks!

Process wait SQL*Net message from dblink /SQL*Net message from client

Hi There,
We have an ETL process that we kindly need your help with. The process been running since Sun, where it transfers the data from one server (via remote query). The process was running ok till last night where it appeared
to have stopped working and/or the session is just idling doing nothing.
Here are some tests that we did to figure out what's going on:
1. when looking at the session IO, we noticed that it's not changing:

had a chat to the infrastructure team and they've assured us that there have been no network outages.
Also, the alert logs for both instances (local and remote) shows no errors what so ever!
Your input is highly appreciated.

Remote tuxedo domain rejects connection from client only Tuxedo JCA Adapter

I am trying to use a client only configured Oracle Tuxedo JCA Adapter 11.1.1.2.1 to connect to a remote tuxedo 10.3 domain. The connector is deployed to a JDeveloper 10.1.3.4 embedded OC4J container. The connector is failing silently when attempting to establish a connection with the remote domain. Locally, the JCA Adapter ntrace logs the following:

I can't determine if there are any problems from these log entries, but the remote tuxedo domain logs the following in the ULOG:
155138.tdtux01!GWTDOMAIN.3495.4.0: LIBGWT_CAT:1073: ERROR: Unable to obtain remote domain id (ypjspNQ5QIPKmOyk1DlAgw==) information from shared memory
155138.tdtux01!GWTDOMAIN.3495.4.0: LIBGWT_CAT:1509: ERROR: Error occurred during security negotiation - closing connection
My understanding is that the client only configuration should connect to a remote tuxedo domain as an anonymous client instead of a peer tuxedo domain, but the remote tuxedo gateway domain listener is acting like the client has to be configured in its dmconfig file before it will allow the connection request. Is there a different kind of listener the client only configuration should connect to instead of the tuxedo gateway domain listener? How can a remote tuxedo domain accept a connection from an anonymous client if the client must first be specified in the remote domain's dmconfig file? Is this a tuxedo 11g only feature? I'm trying to connect to a tuxedo 10.3 server.

Looks like this is an RTFM question. From:

Is the following:
Dynamic RemoteAccessPoint (RAP) Insertion
In order to make default LocalAccessPoint to work, Oracle Tuxedo GWTDOMAIN gateway configuration is required in order to make this simplified /Domain configuration to work.
GWTDOMAIN gateway must be modified to allow Dynamic RemoteAccessPoint (RAP) Registration. If DYNAMIC_RAP is set to YES, it will also update the in-memory database of the status of the connection from those dynamically registered RAP. If the connection from those dynamically registered RAP lost then the information about that RAP will be removed from the SHM database.
GWADM must be modified to process the DM MIB correctly to reflect the connection status of those dynamically registered RAP. When the connection from those dynamically registered RAP lost their entries in the SHM database will also be removed so that the DM MIB query can return the connection status correctly.
The dynamically registered RAP will be added to /DOMAIN configuration permanently. Their existence will only be known when the Session is established. Their existence will be lost when the connection is lost.
The DM_CONNECTION Oracle Tuxedo /Domain DMIB call returns all the connected dynamically registered RemoteAccessPoint. All other dynamically registered RemoteAccessPoint that are not connected will not be shown.
The OPENCONNECTION DMIB request will not be supported to connect to those dynamically registered RAP.
The CLOSECONNECTION Oracle Tuxedo /DMIB request closes the connection and remove the session from those dynamically registered RemoteAccessPoint, and returns its connection status as 'UNKNOWN.
The PERSISTENT_DISCONNECT type of CONNECTION_POLICY will be honored that means when PERSISTENT_DISCONNECT is in effect all connections request from any RAP, whether they are dynamically or non-dynamically registered, will be rejected.
I must have overlooked this section when reading it. Looks like I've got more configuration to do.
Thanks,

SQL*Net message from client - huge wait in trace file

Dear All,
I am facing a performance issue in a particular operation ( which was completed in 21 Minutes earlier). Now the same operation takes more than 35 Minutes. I took a trace for those session ( 10046 level 12 trace ) and found Lot of waits in SQL*Net message from client.
Elapsed times include waiting on following events:
Event waited on Times Max. Wait Total Waited
---------------------------------------- Waited ---------- ------------
SQLNet message from client 611927 10.00 1121.35*
I copied only the highest wait in the tkprof output.
And I found from the tkprof and even in raw trace file this event waits more time after excuting
SELECT sysdate AS SERVERDATE from dual;
Elapsed times include waiting on following events:
Event waited on Times Max. Wait Total Waited
---------------------------------------- Waited ---------- ------------
SQL*Net message to client 115 0.00 0.00
SQLNet message from client 115 10.00 724.52*
Please help me to find out why this wait taking long time, especially on the above query..
Regards,
Vinodh

In awr report , this query taken less than a sec for more than 2000 executions.
Regards,
VinodhGood idea to check the raw trace file. It is important to notice that this particular wait event appears after the fetch of the result from the database. The client receives the SYSDATE from the database server, and then the client performs some sort of action for about 10 seconds before submitting its next request to the database. The SQL statement that immediately follows and immediately preceeds this section of the trace file might provide clues regarding what caused the delay, and where that delay resides in the client side code. Maybe a creative developer added a "sleep for 10 seconds" routine when intending to sleep for 10ms? Maybe the client CPU is close to 100% utilization?

Can we stop shared server from client m/c

Hi all,
Can we stop Oracle Shared and Dedicated server from Client Machine if i am connecting through SYSDBA.
Thanks

Yes. No.
Yes, you can stop shared server. Simply decrease the shared server pool to zero. (see below for details)
No, you cannot stop a dedicated server as "The Thing" that creates dedicated server connections is the Listener. So you will need to stop that.
# stop shared server:
SQL> show parameter shared_servers

max_shared_servers integer 20
shared_servers integer 10

System altered.
