SocketPermission error in applet when accessing the same domain
Hello, my applet downloads the contents of an URI from the same domain, using a relative URI. This should be AFAIK an unprivileged operation and should be always allowed, even for unsigned applets, such as mine.
(In contrast to accessing URIs from a different domain, which requires the applet to be signed or self-signed & confirmed).
Indeed, the applet works perfectly under Windows, both with MSIE+Microsoft JVM, MSIE+Sun JVM and SeaMonkey+Sun JVM and Opera+Sun JVM.
In contrast, under my Gentoo Linux, in SeaMonkey+Sun JVM this doesn't work. Under both Windows & Linux the Sun JVM version is 1.6.0, SeaMonkey version 1.1.7, Java plugin "Java(TM) Plug-in 1.6.0_03-b05". - Everything is emerged from the current stable Portage tree (ebuilds www-client/seamonkey [1.1.7], virtual/jre, dev-java/sun-jdk [1.6.0.03], plus I created a symlink 'libjavaplugin_oji.so' in directory '/usr/lib/seamonkey/plugins' pointing to '/usr/lib/jvm/sun-jdk-1.6/jre/plugin/i386/ns7/libjavaplugin_oji.so'
I have made no changes to my java.policy file. [Yet it seems that such rule as "allow URI access in the same domain" cannot be expressed in this file's language]
The error message I get is exactly what I would get have I tried to access an URI from a different domain. [See below].
Googling as well as searching Sun's forums failed to give an answer. Has anyone have had similar problems? Is it more likely to be just a configuration/Gentoo problem, a more general problem, or perhaps the problem is just between the monitor and the keyboard?
Any help is most welcome. TIA,
Jiri Svoboda

Thank you for contacting us to let us know you are experiencing a problem. Yes, we have addressed the issues we were experiencing earlier.
I believe the problem you are facing is bcause you must use the original user ID you provisioned with your Xfinity Home account. Unfortunately, we only support a single user ID per account on the mobile applications today. We do plan to change this in the future.
I will private message you with the user ID to try on your mobile account.

http://support.apple.com/kb/ht5209 might help you. An iPhone 4 can airplay content from apps that support airplay and iTunes but it cannot mirror. If your game does not have airplay in the app you cannot mirror it to the apple TV so I don't know if you can play just the music. You should have no problem playing your iTunes over airplay though.

ITunes for Windows: Error -9812 when accessing the iTunes Store
So here is the situation. When I try to access our iTunes U site from the public link it works great, when I go thru the link that has me authenticicate it works on macs but on PC's I get the error message "iTunes for Windows: Error -9812 when accessing the iTunes Store" it's happening all thru our campus with PC users. Any ideas?????
We're having similar connection issues, and the error log on our web server says something about a certificate error. I noted that last year on this date there were messages related to certificates. Is it possible they are updated every Dec 2, and we should count on some down time?

iTunes is a program on your computer, it is not "the Internet". The fact that the program runs has no bearing on Internet connectivity.
Maybe if a little more information was supplied, like version of the Operating system on the computer and version of iTunes, then a little more assistance could be provided. -
Accessing the same stateful session bean from multiple clients in a clustered environment
I am trying to access the same stateful session bean from multiple
clients. I also want this bean to have failover support so we want to
deploy it in a cluster. The following description is how we have tried
to solve this problem, but it does not seem to be working. Any
insight would be greatly appreciated!
I have set up a cluster of three servers. I deployed a stateful
session bean with in memory replication across the cluster. A client
obtains a reference to an instance of one of these beans to handle a
request. Subsequent requests will have to use the same bean and could
come from various clients. So after using the bean the first client
stores the handle to the bean (actually the replica aware stub) to be
used by other clients to be able to obtain the bean. When another
client retrieves the handle gets the replica aware stub and makes a
call to the bean the request seems to unpredictably go to any of the
three servers rather than the primary server hosting that bean. If the
call goes to the primary server everything seems to work fine the
session data is available and it gets backed up on the secondary
server. If it happens to go to the secondary server a bean that has
the correct session data services the request but gives the error
<Failed to update the secondary copy of a stateful session bean from
home:ejb20-statefulSession-TraderHome>. Then any subsequent requests
to the primary server will not reflect changes made on the secondary
and vice versa. If the request happens to go to the third server that
is not hosting an instance of that bean then the client receives an
error that the bean was not available. From my understanding I thought
the replica aware stub would know which server is the primary host for
that bean and send the request there.
Thanks in advance,
Justin
If 'allow-concurrent-call' does exactly what you need, then you don't have a problem,
do you?
Except of course if you switch ejb containers. Oh well.

Cannot open 2 Virtual Machines at the same time to access the same Database
Folks,
Hello.
I am installing Oracle Database 11gR2 RAC system using 2 Virtual Machines (rac1 and rac2) on the top of VMPlayer 3.
The VM rac1 and rac2 run correctly when one of them is shutdown.
Their locations are F:\VM_RAC\rac1 and F:\VM_RAC\rac2.
While rac2 is running, I open rac1. But this error message comes up:
Error: "Cannot open the disk F:\VM_RAC\sharerac\asm1.vmdk or one of snapshot disks it depends on. Reason: failed to lock the file."
While rac1 is running, I open rac2. But this error message comes up:
Error: "Cannot open the disk F:\VM_RAC\sharerac\asm1.vmdk or one of snapshot disks it depends on. Reason: failed to lock the file."
The 2 error messages are the same. This means I cannot open 2 VMs rac1 and rac2 at the same time. When we run RAC system, we have to open 2 machines or more than 2 machines at the same time so that all machines can access the same Database Server.
My question is:
Can any folk tell me how to have rac1 and rac2 run at the same time ?
Thanks.You need to disable disk locking, which ordinarily is performed by the first VM to prevent any other VMs from corrupting your vmdk files via uncoordinated writes. You will have to shutdown both of your VMs and edit the *.vmx flat file for each, adding lines like the following (settings taken from workstation 6, but should be nearly identical settings for VM Player 3.x):
http://crosbysite.blogspot.com/2007/10/clustering-in-vmware-workstation-6.html
scsi1.sharedbus = "Virtual"
disk.locking = "false"
diskLib.dataCacheMaxSize = "0"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.dataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "4096"
diskLib.maxUnsyncedWrites = "0"
A few comments:
- your shared disks (scsi1) must be on a separate virtual scsi bus than the boot disk (scsi0), to allow setting the sharedbus flag as seen above.
- you must also ensure the cache parameters and unsynced writes settings are set to guarantee that all IO is immediately flushed to the vmdk file so the other VM can immediately access the latest version of data. -

Error analysis
The system attempted to access an ORACLE instance to which
it is no longer linked.
This situation may arise because the ORACLE instance
has been stopped due to an error or an external operation.
How to correct the error
Database error text........: "ORA-03114: not connected to ORACLE"
Triggering SQL statement...: "CX_SQL_EXCEPTION==============CP "
The current status of the ORACLE instance cannot be determined.
It may be still inactive or the database administrator may have
restarted it.
In any case, all systems that have accessed the ORACLE instance
must be restarted after the ORACLE instance has been restarted.
If you were working on a central system, inform
your system administrator.
If you were working on an external local system, inform
the person responsible for this system.
If you were working on your own local system, restart
the system yourself.
If the error occures in a non-modified SAP program, you may be able to
find an interim solution in an SAP Note.
If you have access to SAP Notes, carry out a search with the following
keywords:
"DBIF_REPO_SQL_ERROR" " "
"CL_SQL_RESULT_SET=============CP" or "CL_SQL_RESULT_SET=============CM006"
"NEXT_PACKAGE"

1. The description of the current problem (short dump)
To save the description, choose "System->List->Save->Local File
(Unconverted)".
2. Corresponding system log
Display the system log by calling transaction SM21.
Restrict the time interval to 10 minutes before and five minutes
after the short dump. Then choose "System->List->Save->Local File

The Windows SMB feature has file locking if multiple users are accessing the same file. Does File Sharing (AFP) on Snow Leopard Server provide similar services?
Were you ever able to solve this problem. I'm having similar issues since upgrading to snow leopard. Four macs connect to a Windows Server 2003 for shared files. Each user has full permissions & when we "get info" it shows read & write permissions. Two of the computers were running 10.4, two were running 10.5. Everything worked properly until upgrading to snow leopard. Some files let me copy, move, delete. Others either just hang up or we get a "no permission" error. Also getting a "pdf is in use" error, even when the file/folder doesn't contain a pdf. We had our IT rep check the server who said everything is in working order. They don't represent macs any longer but feel that it's a mac problem. I would have to agree since this problem only started after the upgrade, and the one machine that was not upgraded (still running 10.5.8) is not dealing with these problems.
Lastly, I would install 10.5 back on all of the computers if I could, but the leopard disk that came with one of the computers wouldn't work with the 2 machines running 10.4 and I didn't see it available at the apple store. I'll buy it if it's still available, but why wouldn't the disks that I have work?

Multiple users accessing the same server.
Ok here is my issue, about 2 months ago I started having issues with Filesharing on my 2012 Mac Mini running Lion server (current update). We have 3 users that VPN into our conpany network and usually access the same folder, 2 months ago they started conflicting with each other. When one VPNs into the network and connects to the server they are fine, if the second one connects to the network they are fine but if the second one tries to access the fileshare they knock the second one off the server. The first one's connection eventually hangs and they have to completely disconnect from the VPN. I am wondering if this was caused by a patch or if there is something else going on. I have tried to reboot the server and checked the logs for anything but I am not seeing what may be causing this. I have restarted the Filesharing in the Server app and still get the same problem, the users are connecting via local credentials to the server. I don't think it is a password issue since either user can log in and access as long as another user doesn't so I am not sure what the issue could be.
any help appriciated,
joshBy 'standard record locking system' do you mean there is nothing I need to do programatically? No block level properties to change?
So you are saying this is just the way it always works. So as soon as one of our call center agents opens a record all I have to do is create a pending update to any field?
But won't another user be able to open the form and just query that record not knowing another user has it open?
