Removing an IIOP User connection to an EJB on JServer

I am writing an application using a servlet engine to connect to an EJB in JServer. I am not using connection pooling because each user will be logging in with their database username. When the session times out on the servlet, I would like to clean up the connection, and release the EBJ/IIOP connection. Is there a preferred method to do this, or should I let JServer time out?
Thanks
Ken

The beans have session lifetime and will be removed/cleaned up when the session is deleted.
The session is constructed when the first JNDI lookup (on InitialContext) to an object (EJB in your case) of a given database instance is made. The session is deleted when there are :
a) no connections to the session
-and-
b) the EJB timeout has expired.
The timeout only starts ticking when there are no connections to the session.

File sharing reports too many users connected

SPECS: Mac Mini Core 2 Duo 2 GHz, 2G RAM, Mac OS X 10.6.4. Other users in office also running similar hardware and Mac OS X 10.6.4.
CLARIFICATION: This Mini is used as a file server in a small law office (4 other workstations). It is running Mac OS X Client, not Server. I refer to the machine as "the server" but wanted to be clear the operating system is the same on all stations.
HISTORY & CONFIG: This system was setup in November 2009. It provides simple file sharing storage for a 4-user law office and runs Retrospect (version 8.1.626) to do some local and network backup operations. At the time it was setup, it was also running Now Up-to-Date Server but that program is no longer supported, and it has been removed from the computer (May 31, 2010). In late March 2010, I installed Daylite Server as a replacement for Now Up-to-Date. All stations are running Mac OS X 10.6.4, and have always been at the most recent Mac OS X 10.6.x revision within a few days of the release of a major update.
PROBLEM: Occasionally, clients cannot connect to the server (and I don't have the exact error message -- next time it happens, someone is supposed to get a screenshot). When this happens, if you go to the server and open the file sharing control panel, then click "options", you will see an impossible number of people are connected. The first time this happened was on April 28, 2010, when it reported 41 users were connected. Mac OS X Client has an upper limit of 10 simultaneous user connections, so you can see this number is not possible. Additionally, these are "phantom" logins because you can execute this command in Terminal to see the IP addresses of any connected users:
netstat -n | grep '.548'
And when I do this, unless there was someone who had logged in prior to the "phantom explosion", it never shows any connections. On two occasions, I've actually been in the office late one night to do maintenance, checked the server before I left and found 0 connected users, then got a call in the morning that the first person who attempted to connect was blocked and the server showed 10 or more users connected.
I do not believe this is some kind of security breach. The server is not Internet-accessible, and as is shown by the netstat command, there really isn't anyone logged in anyway. I consulted with Marketcircle (makers of Daylite) because it seemed very coincidental that I installed their software just prior to the beginning of this problem, but they claim Daylite does not make any use of the Mac file sharing system. But, again, since these aren't real users, I suppose it's possible a bug in their software is somehow upping the Mac's connected user count erroneously?
Restarting the server always fixes the problem -- until it happens again. This Mac Mini is a pretty simple station -- just runs Daylite Server and Retrospect Single Server, plus the basic file sharing. Anyone have any ideas why this keeps happening?

I would say odds are likely this is correct. On at least two occasions I can think of where I verified everything was okay and later discovered a "phantom explosion", a Retrospect backup would have run. Our backups typically run at 3 AM. Is this a known issue with Retrospect? If so... not sure why it doesn't happen all the time. And in my own office I have a pretty similar setup on an entirely different computer that multiple people connect to, and it never does this. Color me confused.

How to send notification when too many users connected

Hi all !
I need to send a notification from my web container when there are over 100 users connected, does anybody know how to do it without using vendor's Api but just JEE Api ?

Hello,
If you create an object that implements javax.servlet.http.HttpSessionBindingListener,
you can define valueBound and valueUnbound methods. I usually call it a User class. Also you
can have a static int, counter, in this class, which is accessible by all
classes (make it public or create increment, decrement and getValue methods). In
the valueBound method, get it to increment the static int, in valueUnbound call
decrement).
Now in the JSP pages, at the top, check if the User object exists in the Session
scope. If it doesn't, create one and add it to the Session. This will
automatically call the valueBound on that object and increment the counter. When
a persons session expires, or the User object is removed from the session, the
valueUnbound is automatically called and the counter decrements.
I usually make this check a seperate JSP page which I include on all the other
pages. Then all you need to do is get the User.counter value at any time to see
how many people are on the system.
Hope it helps

Red-5 how to show live users connected

Hi,
I am working on an Flex application with red-5. It is based live broadcast, the flow is:
1. user connects to red5 and starts broadcasting
2. viewers also connect to same location on red5 and receive live broadcast.
I have to show how many people are attending the live broadcast. I am using remoteSharedObject thanks in advance for any help.

The GUI design/function of Lync is so flawed I prefer not to argue the point.
But to the previous comments, why would Microsoft NOT have an option to a 'compact view'; to see more contacts at a time -- is it because it doesn't fit in with your 'touch' interface? And just how many corporations/companies are using a touch interface
with all their workstations? Why remove features from an application in a so-called upgrade? Is it so hard to understand that desktop real estate is valuable and that's why most companies have two monitors for workstations? Pretty isn't productive, and sometimes
productive can't be pretty...
I recently had to update from Microsoft Communcator for work and at this point, I think I could've vomited a better GUI than Microsoft has 'planned out'.
It's hard not to be sarcastic on this one, but good job on the roll out and execution of Lync Microsoft; good job. Way to look out for the users...
Next time I need a 'train wreck' execution of an upgrade, I will keep you guys in mind.
You'd been a heck of a lot better just replacing Lync with Skype...
Isn't that why you buy ccompanies like Skype for $8bn dollars?

Cannot send email via ActiveSync when user connect from Internet (Exchange 2010 SP3 RU5)

Hi All.
This is the first time I encounter this kind of issue, whenever user connect from the internet they cannot send email from their Phone or Windows Mail App, but they can retrieve email
But when they connect from Internal Network they can send email. I already test ActiveSync from internet using www.testexchangeconnectivity.com and it pass all tests.
I also check the Firewall and all the necessary ports already opened (we even open all ports) , the default TTL on the firewall 3600 second.
From what I read ActiveSync use some kind of HTTP POST or in MS terminology "PING" command, but still have no idea what kind of configuration that should be made to the Firewall so it can pass this "PING" command. Because from what I
see in Android Logcat the problem always related to this PING command

Hi ronaldosy,
How about the work flow of Outlook or OWA on PC internally/externally?
If only phone has this issue, I suggest ask ActiveSync Forum for help so that you can get more professional suggestions. For your convenience:

How to make Adobe acrobat feature to convert SAP Pages to PDF available for multiple users connected to the same server

We have installed Adobe Acrobat X Pro- English,Francais,Deutsch version 10.1.9 in our test environment and tried testing it for converting SAP pages into PDF with a few pilot users. In doing so we faced a challenge, where only one user at a time can use Adobe Acrobat PRO to convert SAP pages in to PDF.As long as the first user who is connected to Adobe Acrobat Pro via SAP isn’t logged off, other users connected to the same server are not being able to get the “Save As” dialog box to save the PDF in their preferred location.
This is a business requirement and we need an urgent solution for the same. Can anyone help us in telling us if this is possible and if yes the how to go about?

It's not something we deal with here, the LiveCycle products are a different world. Key points: Adobe LiveCycle is a range of products, some desktop, some server. LiveCycle PDF Generator is the one you should look at, it comes in 3 editions. License terms are by negotiation. Key management is via its Java API.

How to provide access to multiple users connected to a Dumb switch? (multi-auth/multi-domain)

Good morning everybody,
I am writing on behalf of not being able to implement a desired outcome in our company network. In fact the situation is as follows:
What I want to do is to be able to authenticate users (802.1x authentication) in our company radius server and authorize them access by having a dynamic VLAN assignment in a multi-user environment on one and the same port of a Cisco 2960 switch. So far, the authentication and authorization has been working completely smoothly (there are no problems with itself). The concept involves the configuration of both DATA and VOICE VLANs as I there is also phone authentication implemented. In order to simulate this environment I introduce a Dumb switch connected to my Cisco 2960 Catalyst.
What I have successfully managed to get to work so far is this:
1) On one switch port I have tried the “authentication host-mode multi-domain” and it worked perfectly for a PC behind a telephone, or with one PC connected to a the dumb switch + the telephone connected to another port of the dumb switch. Logically it is the same situation as there is a separation in two domains – DATA and VOICE. Bellow is an output from show authentication sessions for this scenario.
Interface MAC Address Method Domain Status Session ID
Fa0/23 0021.9b62.b79b dot1x DATA Authz Success C0A8FF69000000F3008E (user1)
Fa0/23 0015.655c.b912 dot1x VOICE Authz Success C0A8FF69000000F9009F (phone)
2) On the other hand, when I try the same scenario with the “authentication host-mode multi-auth”, the switch still separates the traffic in two domains and is able to authenticate all users, AS LONG AS they are in the same VLAN.
show authentication sessions:
Interface MAC Address Method Domain Status Session ID
Fa0/23 0021.9b62.b79b dot1x DATA Authz Success C0A8FF69000000F3008E (user1)
Fa0/23 b888.e3eb.ebac dot1x DATA Authz Success C0A8FF69000000F8008C (user2)
Fa0/23 0015.655c.b912 dot1x VOICE Authz Success C0A8FF69000000F9009F (phone)
However, I cannot succeed authentication of many users from DIFFERENT VLANs, neither in multi-auth nor in multi-domain modes.
What I want to get is an output like this:
Interface MAC Address Method Domain Status Session ID
Fa0/23 0021.9b62.b79b dot1x DATA Authz Success C0A8FF69000000F3008E (user1)
Fa0/23 b888.e3eb.ebac dot1x DATA Authz Success C0A8FF69000000F8008C (user2)
Fa0/23 0015.655c.b912 dot1x VOICE Authz Success C0A8FF69000000F9009F (phone)
I want the switch to authenticate the users anytime they connect to itself and for them to have an instant access to the network. (I tell this because I tried scenario 1) with multi-domain mode and authentication violation replace, and it worked but, two users never had access to the “Internet” simultaneously!!!
The configuration of the interface connected to the Dumb switch is as follows.
interface FastEthernet0/x
description Connection to DUMBswitch
switchport mode access
switchport voice vlan XXX
switchport port-security maximum 10
switchport port-security
switchport port-security violation protect
authentication host-mode multi-auth
authentication priority dot1x
authentication port-control auto
authentication timer reauthenticate 4000
authentication violation replace
dot1x pae authenticator
dot1x timeout tx-period 10
spanning-tree portfast
The way I see it is explained in the following steps:
- PC1 connects to the Dumb switch. This causes the Cisco switch to authenticate user1. This creates an auth. session with its MAC address linked to a domain DATA.
- When PC2 connects to the Dumb switch, this causes the violation replace which replaces the recent authenticated MAC address with the MAC of PC2. I would like it once authenticated to appear in the authentication sessions with a link to a new DATA domain linked to the VLAN assigned from the RADIUS server.
Is this possible? I think (in theory) this is the only way to provide authenticated access to multiple users connecting through Dumb switch to the network.
Has anybody ever succeeded in such a configuration example and if yes, I would be love to get some help in doing so?
Thank you
Stoimen Hristov

Hi Stoimen,
I have done a setup similar to yours with the only exception being VLAN assignment. When I used dACLs only, it makes things somewhat easier as the VLAN no longer matters. Remember that the switchport is in access mode and will only allow a single VLAN across it (with the exception of the voice VLAN). I think that is the real cause of your problem.
From what I can see, you have 2 options available to you:
1) Use dACLs instead of VLAN assignment. This means that an access list will be downloaded from the radius server straight to the authenticated user's session. I have tested this and it works perfectly. Just Google Cisco IBNS quick reference guide and look for the section that deals with Low Impact mode.
2) Get rid of the dumb switches and use managed switches throughout your network. Dumb switches will always be a point of weakness in your network because they have no intelligence to do advanced security features like port security, 802.1x, DHCP snooping, etc.
Hopefully someone else will chime in with another option.

SYS user connects at database level, is it correct?

My senior colleague has given me following information about the sys user. I want to know, is it correct?
Since SYS user connects at the database level, therefore, on killing the active session of the SYS user,only the current statement is cancelled. The database session does not disconnect. Instead it continues to run the remaining statements in the script file in case we are running a script file containing a lot of SQL statements.

Instead it continues to run the remaining statements in the script file in case we are running a script file containing a lot of SQL statements.Running a SQL script very likely means SQL*Plus is used. One of two types of Oracle sessions will be created via sqlplus. A dedicated session. Or a shared server session.
A dedicated session can also be local (sqlplus connects "directly" to the dedicated server process), or remote (sqlplus connects via tcp/ip to the dedicated server process).
A server session is usually "killed" using the alter system kill session command. Despite the differences between shared and dedicated server connections, the end result is the same. The session terminates abnormally (session UGA will be released, session will be cleaned up, rolled back, etc) - and the session ceases to exist.
So irrespective of how that sqlplus session runs that script - the session, when killed, will cause a sqlplus failure. And no subsequent script commands would be executed by that Oracle session.
What can happen is that sqlplus continues running, continues reading the script, and continues submitting commands to be executed. However, with the server session killed, there is no server process to service the commands submitted by the sqlplus client. In this case, sqlplus will throw the error "+SP2-0640: Not connected+" after each of the commands it tries to execute after the server session was killed.
The only time when sqlplus will be able to continue is when the session is not killed, but interrupted. The Oracle Call Interface (OCI) supports a OCIBreak() call - allowing the client to interrupt-and-abort the request that its server session is currently executing.
For example, sqlplus sends a OCIBreak() while it waits for a server response (e.g. waiting for the answer to a SQL select query), when the user presses Ctrl-Break to abort that request.
In this case, the session still exists - and the client can issue a new request that the session will service. But an OCIBreak() cannot be triggered (to my knowledge) externally from another Oracle session. You need to send the client process a "break request" (like a Ctrl-Break keystroke) in order to trigger that client process to make an OCIBreak() call to Oracle and interrupt its server process.

OIM 9.1.0.2 Group Membership Removal for Disabled Users

Hello
In OIM 9.1.0.2, when a user is disabled, they are removed from the groups they are a member of within 24 hours. i was wondering if this is a set time and if so, can this be extended to a specified time so membership can be left for a week before it is removed from the user. If you can let me know on this I would appreciate it.
Thanks
Nick

Today, when accounts are disabled, within 24 hours all the group memberships are removed on the OIM side. I would like to change the interval for the cleanup so that when an account is disabled, all the existing group (role) memberships stay assinged to the account then after 30 days of the account being disabled, the group (role) memberships are removed. Not sure if this would be an ORM thing or OIM, but I think it would be OIM since ORM still has the role mappings for users when they are disabled.
Thanks
Nick

Max no. of users connections in essbase

Hi All,
How can i find what is the max. no. of users connections is allowed for essbase. If there is some setting in EAS console or we can define it through MAXL. We are using very old version (version 6- using ESSCMD commands). We have already provided access to about 475 users. 200 more users are waiting for access.
Thanks,
Anchit

Herewith the relevant parameter you can define in your ESSBASE.CFG - it should answer your question:
MAXLOGINS
Sets a limit on the number of user sessions that can be connected to the Essbase Server at any one time.
Syntax
MAXLOGINS n
n Any integer from 1000 to 1048575 is valid. The default value is 10000.
Description
This setting limits the maximum number of user sessions allowed to connect to the Essbase Server at any one time. This number includes multiple instances of the same user.
You may wish to adjust the value of MAXLOGINS to match computer resources, or to more closely manage concurrent ports and user sessions. A concurrent port is used for each unique combination of client machine, Essbase Server and login name. For example, the same user > with five open Excel worksheets connected to the same Essbase Server use one port, but five sessions.
Notes
Increasing the value of MAXLOGINS increases memory use approximately 6 bytes per user session.
If the setting is less than the minimum value, 1000, the value is assumed to be 1000.
Example
MAXLOGINS 50000
increases the maximum number of simultaneous logins possible, from the default of 10000 to 50000. > Kind regards

Connecting to an ejb from another appserver

Hello,
I need to connect to an EJB running on a company's REMOTE Weblogic
appserver. I have done so using normal class files but now I wish to use an
EJB to do so. I am using Jboss but am getting errors from Jboss saying that
it cannot find certain files. Should I be able to connect to the remote
Weblogic server simply by giving JBOSS the url/t3 of it? This is what I am
doing in the JBOSS deployed ejb:
Properties properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
properties.put(Context.PROVIDER_URL, "t3://xxx.xxx.xx.xx");
InitialContext ctx = new InitialContext(properties);
should I just be using JBOSS context factory in my bean code or do I need
weblogic's? Doing this the way I am above, Jboss says it cannot find
"weblogic.jndi.WLInitialContextFactory". So I jared up the parent directory
inserting it into jboss and the next time it told me it couldn't find
com.java.util.collections.ArrayList. So I jarred up the com directory from
weblogic and gave jboss access to it. I now get a classnotfound for a class
which IS contained in the com directory which is now available to Jboss.
This tells me that I am going about this THE WRONG WAY. If anyone can help
or point me to a tutorial telling me how I can use another appserver to
connect to a remote Weblogic Server I would greatly appreciate it.

Easier said then done (getting the higher ups to spend money on an expensive

No, you would need the weblogic classes on the client-side. You'd be

Connecting to an EJB using an standalone client

I'm trying to connect to an ejb deployed on my Application server (not standalone). But i always get the exception: javax.naming.AuthenticationException: No such domain/application

Anyone has any suggestion on what's the problem?
Cant find any topics on internet describing this error :-(
Oeyvin J.

Same error.
The real application (web and ejb's) are running on the same OC4J instance. The Web client are accessing the ejb's on port 3101, so i think this is the correct rmi port.
The server is a part of an infrastructure that are running on the same server, the server is one of two ApplicationServers that the infrastructure (farm) is controlling.
each server has an instance name, the server i was deplying to has name instance2. Maybe i have to give a reference to to the instance?

HT201317 Remove the "By user name" title in Photo Stream

Is there a way to remove the "By User Name" title displayed in the upper right-hand corner of a shared Photo Stream? I sell stuff online and I would like to use the Photo Stream to post photos of, let's say, a furniture set. However, I'd like to maintain a little privacy by not having my first and last name displayed in the shared Photo Stream page.
Is there a way to do that, or would I have to change my profile name entirely to something like Furniture Master, so that iCloud displays that instead?

I don't think Photo Stream is for commercial use.

RAR: Risk resolution options , Remove access from user is disabled

Hi All,
In RAR , After risk analysis, if we click on risk description 3 Risk resolution options are there.
Mitigate Risk
Remove access from user
Delimit access for user
In these options mitigate risk only working.I am using GRC SP 5.
How about other two options , save button is disabled.How to enable this?
can we remove/delimit access to user using these options? any body tested these options?
Thanks n Regards,
Joseph

Joseph,
These functionalities do not exist in the tool and these buttons have been in the RAR for past 2 years. SAP wants clients to use CUP for removing or delemiting access so I highly doubt this will ever work.
