vCenter connections - Idle sessions hang out

Hello

We use the VI SDK 2.5 to Windows XP SP3 to connect to vCenter to QueryPerf to get data from the perf.

A specific user account to connect to the vCenter.

In some cases, we note that there are a few sessions 'dormant' left hanging out.  I see them listed in the console of Administration/Management/Sessions of the vCenter.  I think that these "idle sessions" when the application is connected to vCenter using the API and attempts a "logout" and disconnection fails for some reason any.  It is also possible, I think that, when the application terminates abnormally.  I noticed a case when there is an end to the session "inactive" after 30 minutes of inactivity.

Is there anyway to make the API using the same session or inform not to create a new session, if it already exists for the user?  Something similar to a SQL Server how "connection pooling"?

I appreciate any input in this case.

Concerning

I hope my blog can help you understand the session management:

  • Idle sessions are automatically generated in the database

    I am facing a strange problem to get the very large number of idle sessions generated th the database server which leads to closing of connection is.
    The error reads as "Failed to check-out a demand account held the failure of connection of the Application Module.»
    This happens whenever I execute the following code:

    String amDefName = "amendprgo.model.CSDInvFRCAmendPrgoServices";
    String configName = "CSDInvFRCAmendPrgoServicesLocal";
    ApplicationModule App1 = Configuration.createRootApplicationModule (amDefName, configName);
    String voInstanceName = "prgoHdrRO";
    ViewObject prgoHdrROVO = app1.createViewObjectFromQueryStmt (voInstanceName, "select * from INV_PRGO_HDR");
    prgoHdrROVO.setWhereClause ("PRGO_ID =" + tempRow.getAttribute ("PrgoId") +' and DEPOT_CD = '0' and ITEM_CAT = 'I3' ");
    prgoHdrROVO.executeQuery ();
    If (prgoHdrROVO.getEstimatedRowCount () > 0) {}
    Returns true;

    I know there is a process of creating a connection and the View object in part of model in JDeveloper, but I want to know why this problem occurs.

    As I said before

    Configuration.releaseRootApplicationModule(app1 , true);
    

    My advice is to read the links I gave you!

    Thank you

    If you just want to remove the server from the main server support, just reset the settings in the primary database server as remote destination of archiving to archive for sleep. This will simply stop the transport of the archives of the day before.

    Kind regards

  • Idle sessions

    Hi all

    Can someone please explain me on idle sessions in oracle? I used the following query to get the list of inactive requests:

    SELECT the sid, osuser, schemaname, ROUND ((last_call_et) / (60 * 60), 2) inactive_from_hours, program

    SESSION $ v

    Situation WHERE = "IDLE";

    According to the result of this query, I asked the users responsible for killing their sessions. But many of them have complained that their request is completed a long time ago. I'm in a dead end in this situation.

    When a session is inactive?

    If a query is completed, why he is indicated as inactive?

    Closing the window through which the query ran, will solve this problem? This method has something to do with this bad result?

    The user connects to the database - a session is open.

    Run a query - session been ACTIVE

    Ask finishes - session is shown to be INACTIVE.

    Disconnect the user from the database - a session does not exist anymore in the session of $ v

  • Idle sessions of VMware

    Hi friends,

    We see too many idle session in the sessions vCenter tab. Although it should not harm immeidate, we always want to find a way to hollow compensation even some settings build-in if possible.

    Article, I came across what suggests to change the vpxdclient configuration file where vSphere client is installed. But in our various teams access infra vcenter from different client computers. Is it possible to clear the list of inactive session of vCenter settings the value?

    Thank you!

    Kind regards

    Hari.

    Idle session configured in vSphere client machine and RDP timeout as well through AD.

    Thank you!

  • It is safe to kill idle session?

    Hello
    Recently working on the production environment I've met customer number of connection problem as follows

    sqlplus username/password

    SQL * more: release 9.2.0.4.0 - Production Wed Feb 25 15:46:31 2004

    Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved.

    ERROR:
    ORA-00020: maximum number of processes (%s) exceeded


    After trying several times I connected and identified about 250 idle sessions of the only user of view V$ session.
    I have questions about this scenario.

    (1) I guess that inactive session consume processes, that triggered this error. Please correct me if I'm wrong.
    (2) is it safe to kill these idle without the approval of customers sessions because their status says they are 'INACTIVE '?
    (3) if not then, when idle, do these sessions are certain activities of long durations and because of their laziness oracle mark as inactive?

    My apologies for being naïve... :) Thanks in advance...

    Yes - in a perspective of database instance. Oracle is very robust. It does not choke when a user session suddenly disappear.

    Course from the point of view of the customer? Not really. The client may always require this session - it may even have a unique transaction to validate.

    From a point of view s/n? Joy. Let me count the ways of contentment by waving the old lead pipe and killing sessions... ;-)

    (3) if not then, when idle, do these sessions are certain activities of long durations and because of their laziness oracle mark as inactive?

    You can watch the session $ v and that there should be a column that contains the current state of waiting for event time / elapsed (take a look at the Oracle Reference guide). If this wait state is SQL * Net client message or similar and the wait state has quite a long time (you set this number), then it would be wrong to kill the session in order to allow new.

    Another option is looking at shared server sessions. Here is the light weight in comparison to the server by default. For example a sessions 100 user may be services by 2 dispatchers and 10 shared - server process that oppose an almost 10 x more charge of a 100 process heavy process.

  • Removal of my own (idle) sessions

    Removal of my own (idle) sessions

    What is needed to be able to delete my own sessions "inactive"? At least for me, they are inactive, but Oracle, they are still in business.

    I'm allowed a maximum of 10 simultaneous sessions_per_user on a database for which I have very limited permissions (pretty good read-only). The problem I have is that my internet connection to my agent is unbelievebly bad. I can rarely connect to the Oracle server for more than ten minutes about until I get an error 'connection reset by peer '. And it seems to me that whenever that happens, I don't get gracefully disconnect from the server. Finally, after I reconnect enough times, I will not exceed the limit, and I get the error ORA-02391. The kicker is that once I have get locked, it forces me to jump through two levels of the bureaucracy to get the ADMINISTRATOR to remove my idle sessions. If I wait a few days, the sessions sometimes seem to disappear on their own, but if I need to log in the server path right, well that's won't happen until I can get the DBA to help me.

    I asked if it is possible for me to delete my own sessions, and they said no. My guess is that if I was able to remove my own sessions, then I would have probably allowed to delete the session of anyone. But I hope I'm wrong, and that it is possible for me to be able to remove my own sessions without being able to remove sessions of other people. And that the required permissions to be able to delete my own sessions are give not as me excessive permissions to do other things potentially harmful to the database.

    So, if you were a DBA on a system and you want to grant permission to individual users to delete their own idle sessions, would it be possible? Or would it be opened too big a hole for you to be comfortable?

    The database that I sign too has the following properties:
    Oracle Database 10g Enterprise Edition Release 10.1.0.4.0 - production
    PL/SQL Release 10.1.0.4.0 - Production
    "CORE 10.1.0.4.0 Production."
    AMT for 32-bit Windows: Version 10.1.0.4.0 - Production
    NLSRTL Version 10.1.0.4.0 - Production

    Hello

    To do this DBA should give "alter system" and a specific view select privileges which could open up a hole in the large loop without DBA would be comfortable with it.

  • Firefox hangs out because of norton toolbar - get corrupted files

    Hello

    Recently, Firefox crashes * much * to exit. Sometimes I quickly leave Firefox when I switch to another application, and then a few seconds after the release, the crash reporter will appear.

    I've read elsewhere that it could be caused by the Norton Toolbar. I have the latest version of Firefox 38.0.5 and the Norton Toolbar 2014.7.12.14, and I think they are compatible, but I don't think.

    In addition, I make violations of integrity on my PC Windows 8.1. SFC is display of corrupted files. I was able to set this number, only to return the next day. I understand that a program ending abruptly can cause these corruptions, so I wonder if Firefox is the cause?

    In a world of perfect Mozilla and Norton would work out their differences. For now I have disabled the Norton toolbar, which is not a solution because I need to stay safe as I Browse. I'd rather not spend in IE or Chrome or the other. This isn't a solution.

    Everyone knows about this problem? Does anyone have a solution for my particular case crashing on the release of Firefox?

    Thank you
