• 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.

• 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.

  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!

• 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.

• Idle sessions for machine networking not released (NOT related to RDP)

  In a workgroup environment consisting of a Win 7 32-machine acting as a server and mixed 5 machine (Win 7 64 bit, Win 7 32 bit and XP), I get the following error message on any random on the network machine attempts to access a share on the Win 7 'server: '

  "No more connections are possible at this remote computer at this time because there are already as many connections as the computer can accept."

  In the past, I rebooted just the Win 7 'server' and it fixed the issue - for awhile.  Now, I'm tired of having to do it.

  I completely understand what means this error (i.e. of 20 exhausted max connections) as well on the Win 7 'server' I went into computer management > system tools > Shared Folders > Sessions.  Wow!  A single Win 7 machine on the network had 15 of the 20 connections available, and all these connections had been slowed for days - some as long as the last reboot 15 days ago.

  I restarted the machine and these 15 connections disappeared on the Win 7 server - as one might expect.

  I run "net config server" on both this machine as well as on the 'server' of Windows 7 machine and it sees to the idle disconnect time 15 minutes on both.

  Why these idle connections are not be released?  I'm not sure which side is to blame for hold on these - which side is disconnected?

  I have a theory that somehow connections to hidden shares (for example, //xy-server/backup_machine1$) are initially that as a backup program (Macrium Reflect) uses these, but I'm not sure at this point.

  Thank you.

• Complete the VI Client with PowerCLI Script idle Sessions

  Hello gurus PowerCLI

  I searched the net for a script PowerCLI that would end all the VI client sessions that have been inactive for x period of time.  I found a post on the forums of VMware (http://communities.vmware.com/message/914858?z=zI0r8n) but had no luck with it.  I also found a script created by A.Mikkelsen, to http://www.amikkelsen.com/?p=384 , but that one does not work either.

  Here's the actual script by A.Mikkelsen that is based on code by LucD in the forum mentioned previously.

  END

  The error message I get is:

  I should mention that my knowledge of PowerCLI is almost nothing, so any help in tweaking this script to make it work with PowerCLI 5.1 Release 2 and VC 5 U2 would be much appreciated.

  The error is caused by the fact that you are trying to kill your own session (if it was started long time ago).

  Apparently in vSphere 5. they included a security mechanism integrated to avoid this.

  You can take this by adding a simple test.

  ## max number of idle minutes for sessions to keep$intOlderThan = 60$serviceInstance = Get-View 'ServiceInstance'## get the session manager object$sessMgr = Get-View $serviceInstance.Content.sessionManager## array to hold info about stale sessions$oldSessions = @()foreach ($sess in $sessMgr.SessionList){    if (($sess.LastActiveTime).addminutes($intOlderThan) -lt (Get-Date) -and          $sess.Key -ne $sessMgr.CurrentSession.Key){        $oldSessions += $sess.Key    } ## end if} ## end foreach
  
  ## if there are any old sessions, terminate them; else, just write message to the Warning streamif (($oldSessions | Measure-Object).Count -gt 0) {    ## Terminate sessions than are idle for longer than approved ($intOlderThan)    $sessMgr.TerminateSession($oldSessions)} ## end ifelse {Write-Warning "No sessions that have been idle for more than '$intOlderThan' minutes; no action taken"}

  How do you géreriez idle time session for multiple applications?

  Connect to the OUTER workspace and set a similar attribute in there.

  That is to say - it can be set at the level of the instance and application.

  Slim,

  --> When you see these sessions? and what are the changes on the environment after this observation?

  --> Any change in the parameters of database?

  --> Other services running on this server? If so, what are they?

  --> Also to shoot down two or three reports AWR, a 30-minute snap shot interval would be fine... and download the reports AWR here?

• idle sessions with sql_address = 00

  Hi gurus,
  
  DB: oracle 11g
  application: weblogic
  
  I could see a lot of sessions not valid with sql_address = 00 and Virgin sql_id appearing intermittently and causing connection problems.
  prev_sql_id of the majority of the lines are the same and the sql_text is "select count (*) from dual!
  
  What could be the reason for these invalid sessions? not able to understand the prev as sql_text
  
  Help, please
  Charles

  The sessions are not disabled. They do nothing.
  Also, this causes no problems connecting.
  Applications such as weblogic has several "features".

  -They often perform dummy sql to check the availability of data, such as select count (*) of the double
  -They do not have persistent connections

  This point is addressed by setting up shared server and enabling connection pooling.

• Cisco TMS first activate Idle all sessions

  Hello.

  We have the video conferencing system with Cisco TMS, blades MCU 8420, Tandberg Gatekeeper and Cisco in the series C endpoint, MXP series etc...

  This week we have problems with planning because when we planned to meet his past of in waiting for idle session direct and all sessions the codec says no connection.

  never start the meeting on active sessions.

  then that we end the session or meeting and reprogram this session and that begins at the current session.

  IM verified the conectivity between Cisco TMS and MCU, Endponits its Ok.

  rigth now we rebooted the server and MCU and the GA but when even continue the problem.

  The cisco TMS its located in other areas with transit to WAN network. We reserve the bandwidth with QoS for video, voice and data for im MCUS and endpoints asking its required reserve BW TMS Cisco commands API, Https, Https and other protocols? the problem may be congestion in WAN networks?

  This Protocol should ensure guarantee connect API orders end to end of Cisco TMS - MCUS and endpoints.

  I appreciate your support.

  Giacomo BR P.

  I did not completely understand your description.

  The communication is done on MSDS by HTTP or HTTPS, depending on your settings.

  In general, I would say that the management / follow-up will also through these ports, I would

  expect tickets with problems logging on your TMS.

  I could look at the logs and see: is the Conference properly generated on the MCU.

  is the dial in number okay, can the scope of endpoint the mcu, can the mcu reach end points.

  y at - it something suspicious on the GK, conferences and any other reservation of port

  on the MCU
