Restriction of Session of individual clients

Hello,
How can i make the restriction on server for not connecting sessions
more than 1 from the client machine. i.e. my connection should fail if
my session already connected whether it is active or inactive.
Please reply....
Thanks
Ramesh Ganji

weightings are controlled when you add the column to the template.
the application has logic so that it doesn't exceed 100% within the criterion group, each of your sections individual goals, team goals, corporate goals, will be setup as a criterion in your template with a free enhancement.
then at the criterion level you can define weightings on the "element" level of your template.
so i think the best way you could make this work is with this example:
individual goals = 50%
team goals = 25%
corporate goals = 15%
corporate values = 10%
employee and manager would not have control on the weightings above...
then within each criterion group, as the employee adds things such as individual goals...
they have control..
so goal1 = 10%
goal2 = 20%
goal 3 = 70%
(this 100% reflects 50% towards the overall appraisal weighting)
and then the manager when defining team goals does weightings:
goal 1 = 40%
goal2 = 10%
goal 3 = 10%
goal 4 = 20%
goal 5 = 20%
then similar logic for corporate goals and values...

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

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?

Restricting particular session variables being shared

i am using weblogic 10.3.
I have an EAR with has 2 WAR in it , with session sharing enabled in the weblogic-application.xml . I understand that this will make all the variables that are added in the session to be shared by both WAR, but i want a particular variable added in the session not to shared by both WAR, it should be accessible by only WAR1.
Please help me
Zeeshan

"Restricting particular session variables being shared"
You can use the 'transient' keyword for this purpose, for example,
public class Example implements Serializable {
private String replicate;
private transient String notReplicate;
}The 'replicate' attribute is replicated when the Example object is put in the session, the 'notReplicate' attribute is not.

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!

Detect orphaned sessions for which client is terminated

Hi,
We have REST service. Client will establish session to service. There is max num of sessions limit (10). If I kill client app 10 times, 11th time I will not be able to establish connection to service as max sessions reached. This is because previous sessions
are still active and will be active for session time out period.
Now how to know such kind of sessions for which client app is killed. Is there any setting in IIS for this?
Any inputs on this will be helpful.
Thanks.

Hi,
For this situation, you could try to disable session state in IIS:
Open IIS Manager and navigate to the level you want to manage. For information about opening IIS Manager, see
Open IIS Manager (IIS 7). For information about navigating to locations in the UI, see
Navigation in IIS Manager (IIS 7).
In Features View, double-click ASP.
On the ASP page, under Services, expand
Session Properties.
Select False from the Enable Session State drop-down list.
In the Actions pane, click Apply.
Besides, for more information, you could refer to:
https://msdn.microsoft.com/en-us/library/ee377050(v=bts.70).aspx
http://blogs.msdn.com/b/david.wang/archive/2006/04/12/howto-maximize-the-number-of-concurrent-connections-to-iis6.aspx
And for more detailed information about IIS, it's recommended that you could ask the IIS issues in IIS Forum:

Restrict User Sessions

Hi,
Is there a profile parameter or setting that restricts user sessions by user name or user groups ? I have looked up the thread which suggests changing profile parameter rdisp/max_alt_modes. But this would be system wide.
I really need it to be user group or user or role specific !

Hi Kunal,
Parameter rdisp/max_alt_modes is to change the maximum number of GUI sessions systemwide (or at lease in the instances where the paremeter is set). Theres no way to change the ammount of session for 1 user or a group of users..

Individual client SSL PSE

Hi all,
We tried to create an individual client SSL PSE. In order to do that, we went to: environment ->SSL-> Client identities
But there we got that message:
SAPCRYPTOLIB not installed
Message no. TRUST059
Diagnosis
The SAP Cryptographic Library (SAPCryptolib) is not installed on the application server. It is therefore not possible to maintain PSEs that allow encryption.
Procedure
Download the SAP Cryptographic Library from the SAP Service Marketplace (Alias Security).
Unfortunately, we did not find the relevant library in the market place (maybe it is there but we missed it, and maybe it is not there). The question is how do we get and use that library?
Many thanks,
Tuvia.

Hi r035198x,
Thank you for some solid advice and would rather JPA take care of all the special cases such as keeping the records unique.
Below are the changes made as suggested in ( 1 ), ( 2 ), ( 3 ):
@Entity
@IdClass(EmployeePK.class)
@Table(name="EMPLOYEE", catalog="EmployeeDB", schema="")
public class Employee implements Serializable {
    @Id
    @Column(name="FIRSTNAME")
    private String firstName;
    @Id
    @Column(name="SURNAME")
    private String surName;
    @Id
    @Column(name="DOB")
    @Temporal(TemporalType.DATE)
    private Date dob;
    @ManyToMany(cascade={CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH}, fetch=FetchType.EAGER)
    @JoinTable(name="EMPLOYEE_PROJECT", catalog="EmployeeDB", schema="",
           joinColumns={@JoinColumn(name="FIRSTNAME_ID", referencedColumnName="FIRSTNAME"),
                        @JoinColumn(name="SURNAME_ID", referencedColumnName="SURNAME"),
                        @JoinColumn(name="DOB", referencedColumnName="DOB")},
           inverseJoinColumns={@JoinColumn(name="PROJECT_ID")})
        private Set<Project> projects = new HashSet<Project>();
@Entity
@Table(name="PROJECT", catalog="EmployeeDB", schema="")
public class Project implements Serializable {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name="ID")
    private int id;
    @ManyToMany(mappedBy="projects", cascade={CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH}, fetch=FetchType.EAGER)
        @JoinTable(name="EMPLOYEE_PROJECT", catalog="EmployeeDB", schema="",
           joinColumns={@JoinColumn(name="PROJECT_ID", referencedColumnName="PROJECT_ID")},
           inverseJoinColumns={@JoinColumn(name="FIRSTNAME_ID", referencedColumnName="FIRSTNAME"),
                        @JoinColumn(name="SURNAME_ID", referencedColumnName="SURNAME"),
                        @JoinColumn(name="DOB_ID", referencedColumnName="DOB")})
    private Set<Employee> employees = new HashSet<Employee>();
@Stateless
public class EmployeeSessionBean implements EmployeeService {
    @PersistenceContext(unitName="EmployeeDB-PU") private EntityManager manager;
    public void create(Employee employee)
        manager.persist(employee);
public class applicationClient {
    @EJB
    private static EmployeeService bean;
    public static void main(String[] args) {
    Employee employee = new Employee()
    bean.create(employee);   // line 209
} I have diverged slightly from using simple primary key (EMPLOYEE_ID) to composite key class (FIRSTNAME, SURNAME, DOB) to resemble the actual application.
Also gone back to using non - XADatasources since I am depending on JTA to do all the hardwork on the server side.
Unfortunately, we have hit a snag once again with the following exception still:

EJB 3.0 Session Bean Remote Client

Hi,
I am planning to migrate my EJB 2.1 to EJB 3.0. My old session bean is accessed by a remote java client. I just have to include this piece of code:
Hashtable props = new Hashtable();
props.put("java.naming.factory.initial", com.sun.jndi.cosnaming.CNCtxFactory");
props.put("java.naming.provider.url", "iiop://" + host_ + ":" + port_);I also have to generate rmistubs for the ejb. I have deployed my EJB 3.0 in a Sun Appserver, checking the "Generate RMIStubs" box but I couldn't find the client jar file. In EJB 3.0, should I use the same approach as the 2.1? Or should I use the @EJB annotation? How will I access a remote EJB 3.0 using the @EJB annotation? Thanks in advance.
Regards,
Andrew

EJB 3.0 remote business interfaces are do not have the same interoperability requirements as the EJB 2.x Home/Remote view. If you need access to your EJB 3.0 bean from a legacy client, you can add a 2.x-style Home/Remote view to your bean by either using the <home>/<remote> elements in ejb-jar.xml or the @RemoteHome annotation. Note that the 2.x-style Home/Remote interfaces are completely separate from the 3.0 Remote Business interface.
Also, in SUN's implementation if your EJB 3.0 bean has both a 3.0 Remote business and a 2.x Home/Remote interface there is no default global JNDI name for the bean. You'll need to assign it explicitly using the @Stateless/@Stateful mappedName() attribute or sun-ejb-jar.xml.

Retain session in java client , which invokes a dotnet webservice

Hello Forum,
I am invoking a dotnet webservice using a java client. But I am not able to maintain session in this java client. I googled this, I got many links for the above. But none of the solution was using pure sun api's. My need is to do the same only using sun api's. Please guide. Any help will be appreciated.

Apache HttpClient can do that.

Removing session/thread after client disconnect

I'm using blazeDS to stream data in a push-only sort of fashion so I'm using a StreamingAMFChannel. This channel is configured as such:
<properties>
                <idle-timeout-minutes>1</idle-timeout-minutes>
                <max-streaming-clients>100</max-streaming-clients>
                <invalidate-session-on-disconnect>true</invalidate-session-on-disconnect>
                <user-agent-settings>
                   <user-agent match-on="MSIE" kickstart-bytes="2048" max-streaming-connections-per-session="1"/>
                   <user-agent match-on="Firefox" kickstart-bytes="0" max-streaming-connections-per-session="4"/>
                   </user-agent-settings>
                <server-to-client-heartbeat-millis>500</server-to-client-heartbeat-millis>
</properties>
When a new client subscribes to the channel, a new thread is created. The problem is that when the client has disconnected, the thread remains and will remain not being used (as in a pooling sort of fashion) by future clients. I believe the problem is that, although the client was disconnected, the session never ends?
If this is the case, shouldn't invalidate-session-on-disconnect enable this? What steps are needed to make sure a thread/session dies when the client is disconnected (by idle or call)?
I understand the a session might have multiple channels it is subscribed to, so the idea that one channel can cause a session disconnect is a bit strange (and maybe this is where things fall apart).

The invalidate-session-on-disconnect property comes into effect only when you explicly send a disconnect message to the server. Consider calling channelset.disconnectAll() explicitly from your client. The documentation describes how it can be done.

Restrict the session's time limit

Friends ,
In my oracle database 10g server the process limit is 400 and session limit is 445 .
Look at the following v$resource_limit output :
RESOURCE_NAME CURRENT_UTILIZATION MAX_UTILIZATION INITIAL_AL LIMIT_VALU
processes |399 |400| 400| 400
sessions |406| 408| 445| 445
Now the problem is , in my database more than 100 users are added last week and for this reason my database process crosses its limit (400) . In this case , when a user tries to login then he gets error :
" SQL> conn user@PROD
Enter password:
ERROR:
ORA-12537: TNS:connection closed"
In this moment , I dont want to increase the process value and want to find out the session who are idle for last 10 minues . Is there any parameter in oracle which helps to find out the idle session ?
Also , I want to disconnect those users who are IDLE for 10 + minutes . How can I restrict this without using any profile and also not incresing the v$process value ?
Waiting for reply .. .
