• error "too many concurrent connections" with Gmail

  I started all of a sudden the error "too many concurrent connections" with Gmail with one of my gmail accounss. I googled and it seems like an old problem and I tried all the recommended solutions, but none worked. I have two gmail accounts and the other continues to function properly. Suggestions!

  Reduce the number of labels has solved this problem. Seems specific to TB and GMail (google says you can have hundreds of emails - I have about 60). There are mentions of which can be found via google - but no definitive statement on the problem, with workarounds, etc.. Now I will be anxious the next time I have to add a label, not knowing if it will work or cause this problem.

• Recommendations of the RAM to 7000 concurrent connections

  Hi all

  I need your kind recommendations.

  We have installed oracle database enterprise edition 12 c on windows server 2012. the two 64-bit.

  We have 14000 students. We want to provide to 7000 concurrent user connections.

  How much RAM we forced to 7000 concurrent connections?

  What CPU is necessary?

  Concerning

  You have 2 possibilities to process client connections in the database - dedicated server and shared server (or a combination of both).

  Shared server has a smaller footprint resource wise. In dedicated server, each client connection is served by a dedicated server process. With a shared server, something like a 100 customer connections can be repaired by a pool of 10 shared server process. Shared server requires however a larger SGA as the UGA for a client connection must reside in the global shared memory, and not local in the process of shared server maintenance in this regard. Also, shared server is only really suitable for OLTP and not the customers of type OLAP.

  Shared server can drastically reduce the footprint of server for a large client connection resource base - if configured and used correctly.

  As for Windows. Oracle uses Windows threads. A process unique oracle.exe stops, and all the system processes (process monitor, writer of the db, etc.) and all (dedicated and shared server process) user processes running such as discussions in this process of exe. A thread has a minimum size imposed by the kernel - and a default size (often larger than the minimum) is defined by the process that created the thread.

  The last time I ran Oracle on Windows has been with Oracle 7.1 - so I'm not at all recent with Oracle running on the NT kernel. But I remember correctly, the Oracle default threads thread size is 2MB. Determine the current size and plug that number into the following discussion:

  So for a dedicated server, you'll need 7000 x 2 MB of memory for threads in dedicated server - which will develop according to the UGA and needs PGA of the session of customer served by this thread.

  If is considered shared server, you can try a pool shared of a 1000 servers, with a 100 dispatchers - (1000 + 100) x 2 MB of memory. In this case, the server shared memory can develop due to the needs of PGA. The UGA lies in the SGA however (so a larger SGA is required with dedicated server where the UGA is local and resides in the PGA).

  The average size of the PGA and UGA can be complex - because it depends entirely on the running of this process (shared/dedicated) server code. Lots of bulk code treatment? You can expect PGA and ramp up a lot as a binder in bulk and extraction in block needs memory to the process.

  Whatever it is, you need a 64-bit platform to a 64-bit operating system.

  Issue. Why Windows as a server database? Oracle Linux as the operating system is in my view, greater flexibility of choice ito, scalability and costs.

• NX3000 concurrent connections

  Does anyone know what a reasonable number would be for the maximum number of connections on a single nx3000?  I actually know the real storage will have an impact as well on this, but I need to know if the nx3000 could be a cause of a potential bottleneck.

  Thank you

  Kevin

  You are running Windows Storage Server 2008 on the NX3000? From what I could find in Windows Server 2008, the default limit is 16 777 216, which is, in effect, unlimited. In reality, the real storage will be dependent on your individual network configuration.

• Block of concurrent connections

  Hi, I'm trying block simultaneous connections.

  What I've done so far:

  I added a new column in the table called connection connected, who holds the values 1 or 0

  When a user connects, it updates the value 1.

  It will open a session to the user that has the status is 0.

  When users click on logout, it gives the status 0

  The problem

  If the user closes the browser just, how is the system supposed to know that the user connected status should be 0?

  I reasoned that the onSessionEnd method would do the trick. When the session expires, it simply updates the database for this user to 0. So I put in the code but nothing.

  < cffunction name = returnType 'onSessionEnd' 'Cancel' = >
  < cfquery name = "updateloggedstatus" datasource = "datadsn" >
  UPDATE usermanagerlogin
  The VALUE logged = < cfqueryparam cfsqltype = "CF_SQL_INTEGER" value = "0" >
  WHERE userid = < cfqueryparam cfsqltype = "CF_SQL_VARCHAR" value = "user1" >
  < / cfquery >
  < / cffunction >

  In another application, I used the onSessionEnd method succesully. I used it to remove items that were in the shopping cart, which were in the database, who stopped was not complete.

  < cffunction name = returnType 'onSessionEnd' 'Cancel' = >

  < cfargument = "SessionScope" required = True name / >
  
  < cfquery name = "deletesessionendticket" datasource = "tickdsn" >
  DELETE FROM tbltick

  WHERE oid = ' #Arguments.SessionScope.oid # '.
  AND ordered = < cfqueryparam cfsqltype = "CF_SQL_INTEGER" value = "0" >
  < / cfquery >

  < / cffunction >

  The difference between the two is that the new application is developed in cf9, while the older app was built in cf8

  In the current application, the session ends successfully, it asks me to login, but the onSessionEnd method is not executed.

  Any ideas?

  Very much appreciated.

  What I did is I tried to have the status of the logged on user to update on '1' just at the moment where the user connects and then update the '0' State when the user disconnects. When someone tries to use the same account from another place, and the status of this account is '1', that the user would not have recorded.

  I strongly suggest that you go in the other direction.  Instead of not to allow the opening of the current session, put an end to the previous state of the connection.  Otherwise you're condemning those who may have logged on a computer, that they no longer have access from the possibility of using another computer.  For example, someone connects to work, go home and can not connect because they are connected to work.

  What are you tryting to make in the case of OnSessionEnd?  HOW is - it does not work?

  P. S.

  Have you ever noticed significant differences between these two WHERE clauses?

  n_kip wrote:
  
  WHERE userid = 
  
  WHERE oid = '#Arguments.SessionScope.oid#'
  

  One uses a literal string 'user1', the other uses a variable "#Arguments.SessionScope.oid #".  Also the premiera would be using a variable not defined if changed to "#user1 #" while the other uses a variable in the "SessionScope' structure that is passed as part of the"Arguments"when the end of session event is triggered.

  It is important to remember that the session event fires it is several extended variables that no longer exists, over the scope of the session itself.  The session is terminated, the scope is no longer valid.  So what was in the field of application is passed in argument of the function so that the data can be used in the event handler.

  P.P.S.

  I wanted to remind you of your original message that the event onSessionEnd has little or nothing to do with when a user closes a browser.  Your browser does not go back to all the web sites you have visited and each say "Kip closed me ', and you probably wouldn't want to do.  All servers can do is wait and wait and wait and if it receives no new applications containing known identification of an existing session data in a certain period of time then close the session.  It's the session end event fires and the onSessionEnd handler to be executed.

  You CAN configure only the identification data--(CFID et CFTOKEN) or JSESSIONID - normally stored in cookies to "session cookies" which are only stored in memory by the browser and retired by the browser when it is closed.  So if a user opens a new browser connects to your server before the previous session has expired, the browser will present cookies previous but rather presented nine by the server, thus creating a new session.  And the old one will be left to die his timeout expires.

• Concurrent user connections to vCenter

  Hello

  We have about 50 virtual machines on our infrastructure with ESXi 5 5.5. hosts. They are all machines Windows 7 and users access via vCenter console (they can use the RDP sessions for different reasons). Now, I would like to know how this is handled by the vCenter? Can this has led to a kind of overload on the vCenter server or can it lead to some other performance issues? There are about 15 to 20 concurrent connections but about 50 in total. I couldn't find any documentation on the number of connections could cause the vCenter overload and no valid explanation would be appreciated.

  Thank you

  Hello

  This isn't really the best practice, but you do not hit the limit yet.

  Take a look at a maximum of configuration: http://www.vmware.com/pdf/vsphere5/r55/vsphere-55-configuration-maximums.pdf

  It says 100 simultaneous vSphere Client connections and 180 simultaneous vSphere Web Client

• CIP for EthernetIP connections

  Hi all

  I was wondering how many connections CIP for beacon Communications EthernetIP are there?

  Also, I would like to know how I can it read a subtag, as a program label, using the VI Tag EthernetIP reading to read from a PLC.

  #1. We support a maximum of 128 concurrent connections for incoming and outgoing requests.

  #2.

  In general, the tag name is exactally what you see in RSLogix5000. Tags controller

  you create the show upward in the worksheet "Tags Controller". My understanding is that the

  only difference between program tags and tags controller is scope. Only tags controller

  are accessible outside the controller however.  If the data type can be extended then

  RSLogix shows you the syntax to access subelements.

  If I add a controller called "TestArray" tag, which is a type of table DINT [3] in application, I

  It can get to one of the following ways:
  -By "TestArray" - is / prepares the array of items 1-3, according to the count parameter
  -By "TestArray [N]" (where N is a clue) - Gets or sets the array starting at offset N
  -By 'TestArray [N].0' - Gets or sets a BOOL individual bit of FORCE to offset N

  From my understanding, 'program tags' are like local variables in a C program. They are

  restricted to be accessible only from the scope, that they are declared in, which in this case

  is a particular program. As much as I know there is no way to access these premises

  variables through the ControlLogix EtherNet/IP interface. If you declare them in the

  "tags controller" then they are as globals in C and is accessible from other

  programs on the PLC and externally of the automaton, as via EtherNet/IP.

  If you want to access the data in local variables of out of their limited reach.

  Perhaps their scope should not be declared as a local in their program. If you are working

  around the existing code, my best guess is that you would have to have the data mirrored somehow.

  I would suggest adding a level in your ladder logic to any variables you need to mirror

  in a controller or tag a set of data in your LabVIEW System. A simple

  experience, I do not think that RSLogix5000 allows you to simply alias tags controller program

  Tags (and it would defeat the purpose of limiting their reach in the first place...).

• Maximum number of connections at the same time of the print server?

  in our society, we have same HP LaseJet P2015 printer for about 90 users. printer was attached with the XP machine, and we have had no more (more simultaneous then 10) connections. After consulting with one of my friends I purchsed impression D-Link DPR-1020 sever. Now I m not sure how many concurrent connections could be maximally & what time interval is for each connection (XP, it is 15 minutes)?  I also need advice for the installation of a shared printer said to XP client machines

  Waiting for an answer urgent nice

  Simultaneous connections in XP is 10, until all have been disconnected. You will need to contact support on installing printer.

• Sharable desktop to any number (say up to 50) of users in Windows XP and Vista when all are connected to a wireless ad-hoc network? Or is there a limit on the number of users that can be shared? ___Thanks

  Need to have this configuration in a classroom environment.

  I don't know what you mean when you ask a desktop or sharing users.

  A network computer can share files and printers with other computers, but there are limits that might make it unusable for you.  Windows XP and Vista allow 5 or 10 concurrent connections by other computers, depending on the version.

  You need an operating system of Windows Server or Linux server to allow for more concurrent connections to shared files and printers.

  I also fear that an ad - hoc network does not work well with 50 computers.

• Connection to Ports transferred to a LRT224 of the internet

  Having just Port Forwarding working on my LRT224 (thanks Chad!), I have the following questions:

  All transferred ports will be visible on the WAN IPs?

  example: forwarded Port 550, IPs WAN; IP1.com and Ip2.com - connections are possible on EACH Ip2.com:550 or Ip1.com:550

  If the answer to the first question is 'yes', then can the LRT224, the active support of concurrent connections, i.e. the TWO Ip1.com:550 AND Ip2.com:550?

  I currently have the WAN configuration in failover mode, however, I would like to know if the WAN2 (Ip2.com:550) connection would be available when the router did not breach the wire, i.e. normal running.

  autodrivel wrote:

  Hi Chad,

  After reading your reply and in turn, then read the user's Guide, let me clarify my original question.

  The LRT224 is currently setup in failover mode of connection with WAN1 as the primary WAN.

  Reading the manual (and your response); in normal operation, only the connections that are made to WAN1 will succeed, my initial example, that means only incoming connections to Ip1.com:550 will succeed, incoming connections to Ip2.com:550 will fail.

  When failover mode, the reverse will be true;  only incoming connections to Ip2.com:550 will succeed, incoming connections to Ip1.com:550 fails.

  The above assumption is correct? Yes

  Question, when the installer in failover mode and function normally (i.e. all traffic directed by WAN1), is it possible to explicitly road some thorough traffic WAN2 using, for example, static routing rules OR not Mode failover blocks all access to the WAN backup, except to failover? WAN2 is completely disabled until failover

  Reviewing the configuration of the load balancing.

  Your response the following assumptions are correct:

  If all the connections to the forwarded port lights WAN1, I need to configure the appropriate binding protocol to ensure that all responses sent off WAN1 - Correct? Yes

  In a situation where WAN1 is down and the traffic is received on WAN2 only protocol links above would prevent a connection to the transferred via WAN2 port to function properly, or the LRT would ignore the links if it knows that the WAN1 is down? I have not tested this scenario but I guess that the binding of the Protocol would be ignored with WAN1 downwards. Worst case you will need to temporarily disable the protocol binding rules.

  If the answer to the question above is "the connection would fail", then I must activate an appropriate set of links to WAN2 Protocol not simply disable the existing ones would be sufficient if necessary.

  Thanks for your help with these queries

• Concurrent logins on Windows 7

  Windows XP Pro allows 10 concurrent connections for file sharing. Number of concurrent connections WIndows 7 allows.  House? Activities? Ultimate?

• Number of simultaneous connections that I have in a shared folder on Windows 7 Professional?

  I just need to confirm something.

  Is there a limit the number of users who can access a shared folder on a Windows 7-based computer at the same time?

  As far as I can see the limit seems to be 20 users... the reason why I say that it is when you share a folder, you cannot increase the limit to users who access the folder above 20?

  The solution would be to install the server operating system instead of a workstation OS.

  Any thoughts would be appreciated.

  The limit is 20 concurrent connections. Remember, however, that one device can do multiple connections.

  In any case you would be much better at this sort of level with an operating system server in any case. Office of the OS are not intended to be used for sharing files on this scale.
