Hi ,
I got an issue in Performance testing. we are not using connection pooling in clinet side. I want to check how many connections still opened , which class it opened when i got Maximum connectioned reached exception. Kindly let me know if any body have idea to solve this .
Thanks in Advance,

... anybody have idea to solve this. In the client add code to keep track of how many connections are open
and display this and a stacktrace when you get Maximum Connections Reached Exception.
Even if you were using connection pooling
the database can still reject connections above a certain number of concurrent connections.

  • Application Maximum Connection Reached

    Hi there,
    I have installed a new Application Server and I have my forms and reports running on it. My users have receive an error as above. It seems the AS can only allow 20 max concurrent user?
    How can i enlarge it? My server should be able to cater to more than that.

  • ISA 2006 slow response, connections timeout, maximum limit reached?

    Hey guys, 
    I've been having an issue with a client's ISA Server for the past couple of weeks and haven't been able to understand why this is happening.
    They have a couple of ISA Servers Enterprise Edition in an array. This ISA Servers give Internet access to the entire company. They have significant amount of traffic through a Cisco Iron Port that all the users proxy settings are configured to this device
    and the Iron Port forwards the requests to the ISA Servers.
    This implementation have been working fine for months, until a few weeks back that started to have slow response problems from the ISA Servers.  Analyzing the reports from the ISA Servers, I've noticed an increased amount of traffic a few times this
    has happened and mostly from the Iron Port. The Cisco people says this increase amount is due to the fact that the ISA Server stops responding and new requests are made at the moment from the device. We have configured the Iron port IP in the exceptions of
    the Flood Mitigation Settings of the ISA Server, and configure it to take more than 20,000 connections.
    Still after this configuration, the same problem raised a couple of days back. The ISA Servers stops responding and they need to be forced shut down and restarted to get them back to work.
    There are also some errors from some other internal IPs that it reaches maximum connection limits, but these are about 10 errors like this only. I was thinking maybe there are some infected computers or something but they said that they scanned the ones
    that show the errors and nothing is detected.
    From the ISA reports of the time of the incident, I saw that it reached more than 15,000 concurrent connections. More than double of what it usually handles throughout the day.
    I don't know if there is like a connection limit that the ISA can handle before it hangs of something? 
    Is there any ideas on what can be happening with this? 
    Thanks for any replies!

    Hi,
    Have you check the Event logs on the ISA Server? Any error?
    You could use ISABPA to do some basic troubleshootings.

  • ASA5510 - Maximum connect time

    Quick question.  I have configured the "Maximum Connect Time" as unlimited in my group policy but when a connection is established it shows a "Conn Time Out: 120 minutes".
    The connection does get dropped with this timer.  Any idea how to actually make it unlimited and why it get sets to 120?
    I having a problem with SSL phone clients dropping throughout the day and think this may be the cause.
    Thanks

    I ended up rebooting the ASA this morning and it fixed the issue.  Right away the timeout changed to what I had configured it to be and I was also able to make changes.
    Here's the response from TAC.  Thanks for helping with this.  Much appreciated.
    "I am glad that the issue was resolved on a reboot. Might be that svc sessions were stuck in the memory for some reason and the same sessions would be invoked every time you connected rather than tearing it down and creating a new svc session.
    Once rebooted I believe the sessions stuck in memory were cleared and new sessions came up as a result the issue vanished. I shall surely update you as I have an update from the devs on this."

  • LDAP "ServerListener" stops responding (Max number of connections reached)

    Hi --
    The last four work days, in the evening, our OAS 10G server stopped processing portal logon requests. The response to login requests was this message:
    Internal error WWC-00006 Unexpected error
    encountered in wwsec_app_priv.process)signon
    (User-Defined Exception) (WWC-41417)
    An exception was raised when accessing the
    Oracle Internet Directory 81: Can't contact
    LDAP server. Details:
    Operation dbms_ldap.simple_bind_s (The message also included other details such as the host, port and DN, and a reference to error message WWC-41743.)
    Suspecting an LDAP problem, we looked on the server, and in ORACLE_HOME/LDAP/LOG I found recent log files (oidldapd[instance]s[pid].log) with several megs of messages that look like this:
    2005/06/17:17:59:33 * ServerListener :2 * ERROR :
    ServerListener : Max numbers of connections reached.
    Num Conns = 874, Max Conns = 874, Closing the
    connection. These messages repeated, several times per minute, overnight and the next day until I restarted the server. The same thing happened again the next night.
    A metalink search pointed to docid "293391.1" which, in part, suggests that the problem may be caused by improper programming, and that the solution may be to, "investigate the applications that connect to OID and where possible modify them to perform an explicit disconnect."
    Does anyone have any reference to how an application can perform an explicit disconnect from the OID? We do have a relatively new application which follows the "Java API for Oracle Internet Directory" -- documention found here: http://download-west.oracle.com/docs/cd/B10501_01/network.920/a96577/oid_java.htm -- but in that document we cannot find any reference for how to "perform an explicit disconnect".
    The application already calls the "context.close()" method, which according to the documentation closes the connection to the OID, but we cannot find any other "explicit disconnect". And, since the problem happens even though our app is already calling the context.close(), there must be something else.
    Opened this up as a Metalink question related to Portal, but they said it's not their problem, and we should ask over here.
    Any thoughts?

    Looks like that's helped. While the errors persist, OID isn't dieing.
    For anyone with similar problems, it looks like docid 437493.1 is useful. Upgrade clients to at least 10.2.0.3 to defeat a sqlnet problem.
    Just tried it with the 10.2.0.5 patchset and it seems to be working and not generating the 104 error on the OID server.

  • Maximum connections allowed for AMS 5.0.1

    How can I find out the maximum connection allowed for adobe media server 5.0.1 standard license?

    ...that would depend on your application.
    For a one-way video-on-demand system that streams recorded video at the user's request. Adobe Media Server serves only one stream to each user.
    Here are the bandwidth calculations you would make:
    Calculating server bandwidth needs (BWs):
    BWs = N × S
    where N = number of simultaneous users (subscribers)
    and S = average bitrate of encoded A/V content
    For example to calculate the overall server bandwidth needed to stream video encoded at 500 Kbps to 1000 simultaneous users:
    500 Mbps = 1000 × 500 Kbps
    The above assumes that content is encoded at a constant bitrate. Most often, however, you will vary the bitrate of the content to suit the viewing audience. This affects your bandwidth needs at both the client and server level.
    For example, suppose you estimated that half of the 1000 simultaneous users were going to connect via 350 Kbps DSL modem and the other half via 3 Mbps cable modem. Suppose further that while the video encoded at 500 Kbps was appropriate for the cable viewers, you wanted to encode a separate video at 150 Kbps for the DSL modem users.
    In this case, the total bandwidth required of the system is lowered to 325 Mbps:
    325 Mbps = (500 Kbps × 500) + (150 Kbps × 500)
    This help ?

  • ## NEED HELP ## Weblogic Managed Server Holding Maximum Connections

    In one of our weblogic setup, we have weblogic cluster with 4 members. This cluster has been setup with 2 physical servers, each server having 2 cluser members like below...
    Host Server 1 : ManagedServer1:7003, ManagedServer2:7004
    Host Server2 : ManagedServer3:7003, ManagedServer4:7004
    Cluster member of ManagedServer1:7003 holding maximum connection to HostServer2 and same cluser member of ManagedServer3:7003 holding maximum connection with HostServer1.
    As my assumption, since members are in cluster, heartbeat between the members (Host Server 1 : ManagedServer1:7003 and Host Server2 : ManagedServer3:7003) are holding the connections.
    Currently each managed server 8000 to 10000 connections holding as ESTABLISHED.
    Please let me know, what may be the reason, but other members of same cluster are fuctionality fine.

  • SCOM 2007 - SharePoint 2007: Maximum connections counter

    Hello,
    I am trying to locate the "Maximum connections counter" for SharePoint 2007 using SCOM 2007. I don't see it so far!!!
    "Web Service - Maximum Connections" does not show anywhere any idea?
    Thanks,
    Dom
    System Center Operations Manager 2007 / System Center Configuration Manager 2007 R2 / Forefront Client Security / Forefront Identity Manager

    The object is Web Service, which then has several different counters, which then might have several instances.
    If this performance object is something you want to monitor for, and it is not included in the mp, then you just need to create a performance monitor or collection rule, depending on what you want to do with the data.
    The Exchange 2013 MP, for example, has no performance collection rules.  So it's very possible, while the product group wanted to include everything most people need, they could have forgotten or were just not able to do so before they had to release
    the mp.  The MOSS 2007 MP has been around for years, was never updated, and isn't one of the better mps from MSFT.  So if you want to extend it with a custom management pack, or just add something via the console, then you should be fine.

  • Maximum Connections Oracle can provide

    I have this query, how many maximum connections does oracle provide to any applications server.
    I am aware that the number of connections are configurable. But i wanted to know the maximum number of connections after which there is a possibilty of oracle to crash, or after these particular number connectins oracle wont support any more connections.
    Please help me with this, as im in desperate need of a solution.
    Thanx for your time.
    Nikhil

    There is no functional limit to the number of connections Oracle can support. There may be some internal limit (i.e. session ID may be an integer, which would limit you to 4 billion connections on a 32-bit system) but I've never heard of anyone actually hitting such a limit. In reality, you will be constrained by your hardware long before you are constrained by Oracle.
    Unfortunately, estimating how many connections your particular hardware can support is not trivial. It depends, obviously, on your hardware, but it also depends on your application and on how your database is configured-- shared server vs. dedicated server would be the largest factor here.
