SNAP session in CatOS
Hello,
How do I make more than 1 SPAN sessions on CatOS 6500 switch?
Hi Kapishhohole.
To create more than 1 SPAN session on your cat6k with CATOS you have to use "create" keyword.
Something like this
set span tx create
Remember few guidelines
If you do not specify the keyword create with the set span command and you have only one session, the session will be overwritten. If a matching destination port exists, the particular session will be overwritten (with or without specifying create). If you specify the keyword create and there is no matching destination port, the session will be created
I am posting you the link for cat6k span configuration on catos please read the span session limits and config guideliens

Does WL console provide a snap shot of active http sessions ?
Hi all,
Does WL console provide a snapshot of active http sessions ?
The list of users currently logged in for a web application in admin console ?
Regards,
HarshaYes you are right.
But does it show the list of user names which are logged in active sessions ? -
Performance issue showing read by other session Event
Hi All,
we are having a severe performance issue in my database when we are running batch jobs.
This was a new database(11.2.0.2) and we are testing the performance by running some batch jobs. These batch jobs included some inserts and updates.
I am seeing read by other session in top 5 timed events and cache buffers chains in Latch Miss Sources section.
Please help me to solve this out.

Audition 1.5 has problem playing back MT session if I have a ton of stretched clips
I might be doing something AA is not designed to do, I don't know. Perhaps (I wish) there are a lot easier ways of doing this, but I have a band that recorded, with a song that has 8 vocal tracks, singing as a group. However, they don't all start every word/phrase exactly at the same time, but should - therefore I use the clip stretching abilities in MT to cut the track up each place it's off and stretch it to fit. Normally I don't need to stretch it much at all, but after that tedious job is done the overall project sounds a lot better.
However, now I have this session that has maybe 150 stretched clips (pretty crazy, huh?) and it takes about 30 minutes or more to open. Problem is, now it won't play back decently for some reason; certain tracks sound like a bunch of garble and warble - nothing that can be made out. I do not know if all the stretched clips have anything to do with it. The wave files appear the same as before - example, you can see where a louder portion of audio is but it is nothing synced with what I hear on the speakers.
I should also mention that I had an under-rated computer run AA one time and the same thing happened there so I thought it just got tired and so I restarted AA and it worked fine after that. Here I also restarted AA but the problem is not better - worse if anything.
Some tracks play fine, others don't. Another thing of interest is that I have only stretched the vocal tracks; by far the worse garble is on the instrument tracks; they even play back as quirks and garble in Edit View if I go there.
Anyone have any solution why this happens? Am I over doing AA in some way?
Also, is there a more automated way of matching and syncing vocals? I'm talking about them being .1 - .01 seconds off the beat; is there some way AA will automatically stretch clips to match beats with - say - the beat markers?I am not surprised at all by your reply!
I would do that, soon as I'm done with stretching/timing adjustment; thing was I was still 10 seconds from the end when it started acting up. But Just as a safe precaution in case it would do something like that I had already backed up a couple of times so thankfully I don't need to do it all over again!
So, you don't think that "set beat markers" (or something like that) can be locked to beats in MT? For example if I run the "Find and Mark" beats in EV and then use those beats to snap to the closest beat in MT, stretching the file as need be in order to get it there.. ? Maybe I'm dreaming out of this world.. Next time I'll have to force my clients to sing until they sing it dead on right!
Thanks for your response! -
I'm using iMovie to prepare a short holiday video. Snap to beat markers worked great for the first song but doesn't seem to work when I try to extend my project with a second song and more video and stills. I dragged in the song and marked the beats but when I bring in stils and video clips they just ignore the beat markers. Can anyone help please. Thanks.
I am having the same issue. The first song and beat markers work great. I add a second song and set beat markers. When I add photos, the appear at random spots with random lengths. I haven't seen a pattern yet. Spent 30 minutes on this topic at my last 1:1 session in the store. No luck figuring it out.
One work-around might be to create one song per project (so beat markers work), then combine the two (or more) projects. But I'm not sure if that's possible or how to do it.
Thanks for any help on this. -
How do you turn off the Auto-Maximize Snap Feature
Hi,
I am sure that the auto-maximize is useful but there are occasions when I want to push a window out of the way to the top of the screen. I use this so I can either keep it open and work on other windows or when I have a large spreadsheet and every pixel is needed. It would be useful to over-ride it by holding down a key(s) for those occasions.

Hi,
Thank you for posting.
We can do this to enable the keyboard actions and disable the mouse actions:
1. Please go to “Control Panel - Ease of Access Center”.
2. Go to “Make the mouse easier to use” and check the item “Prevent windows from being automatically arranged when moved to the edge of the screen.”.
3. Then go to “Make the keyboard easier to use” and uncheck the item “Prevent windows from being automatically arranged when moved to the edge of the screen.”.
After applying the settings, if you drag the window to the edge of the screen, it will not be “auto-maximize”; and you can use the function with the hotkeys (Win+Up, Win+Left Win+Right,etc.).
Hope this helps.
Nicholas Li - MSFT
Seems like a strange way of doing it, however it still does not work as intended, the behavior i am seeing is this.
1. Please go to “Control Panel - Ease of Access Center”. no problem
2. Go
to “Make the mouse easier to use” and check the item “Prevent windows
from being automatically arranged when moved to the edge of the
screen.”. no problem mouse will not snap windows problem hot keys disabled
3. Then
go to “Make the keyboard easier to use” and uncheck the item “Prevent
windows from being automatically arranged when moved to the edge of the
screen.”. no problem hot keys enabled problem mouse snaps windows as setting is now unchecked that was checked in #2
In addition to this behavior if “Prevent windows
from being automatically arranged when moved to the edge of the
screen.” is checked it only applies to the current session as davehc1 noted. The only way i have found to keep the setting from reverting back to on is to alter the registry entry HKEY_CURRENT_USER\Control Panel\Desktop\WindowArrangementActive -
PowerShell 2.0 - When to use SqlServer Snap-In
Hello there,
Just started learning about sending Sql Server command through PowerShell.
I understand that we can use .Net objects like SQLConnection, SqlCommand (just like we do in C#) to send the CRUD request to Sql Server database (as $sqlcmd = New-Object System.Data.SqlClient.SqlCommand...)
However, I was reading about Provider and SnapIns and have two doubts. Below is the snippet from my PS v2.0 window:
PS C:\> Get-PSSnapin -Registered
returns:---------------------------------------------------------------------
Name : SqlServerCmdletSnapin100
Name : SqlServerProviderSnapin100
#If I see what commands are available in above SnapIns, I get following:
PS C:\> get-command -module SqlServerProviderSnapin100
#returns:---------------------------------------------------------------------
CommandType Name Definition
Cmdlet Convert-UrnToPath Convert-UrnToPath [-Urn] <String> [-Verbose.
Cmdlet Decode-SqlName Decode-SqlName [-SqlName] <String> [-Verbos.
Cmdlet Encode-SqlName Encode-SqlName [-SqlName] <String> [-Verbos.
PS C:\> get-command -module SqlServerCmdletSnapin100
#returns:---------------------------------------------------------------------
CommandType Name Definition
Cmdlet Invoke-PolicyEvaluation Invoke-PolicyEvaluation [-Policy] <PSObject.
Cmdlet Invoke-Sqlcmd Invoke-Sqlcmd [[-Query] <String>] [-ServerI.
Two questions:
1. Do I need to Add-PSSnapin only when I need to run above commands?
So, I don't need to import any snap-ins if I want my PowerShell to use .net framework objects to communicate with SQL Server.
2. I can send any CRUD request to database using SqlServerCmdletSnapin100 command 'Invoke-Sqlcmd'.
Which one is preferred method of sending CRUD requests - 'Invoke-Sqlcmd' or .Net Framework objects?
Can anyone please clarify.
Thank you!Hi Iniki,
You only need it to perform the exposed commands. You can use .NET types without them.
I recommend doing it all with one tool - if you're going to use .NET, do it all in .NET. That way, all your trouble will be in one spot. And if you're already familiar with the C# .NET way ...
I implemented this with .NET types, especially since I could add better connection handling for the interactive Shell of our techs (They can register connections, manage them, declare a default connection to use and so on) ...
Cheers,
Fred
Ps.: Oh, and of course I implemented my own Invoke-SQLCommand function, so users can use it comfortably in interactive sessions. If you got regular admin users, they need Functions / Cmdlets to use ...

45 min long session of log file sync waits between 5000 and 20000 ms
45 min long log file sync waits between 5000 and 20000 ms
Encountering a rather unusual performance issue. Once every 4 hours I am seeing a 45 minute long log file sync wait event being reported using Spotlight on Oracle. For the first 30 minutes the event wait is for approx 5000 ms, followed by an increase to around 20000 ms for the next 15 min before rapidly dropping off and normal operation continues for the next 3 hours and 15 minutes before the cycle repeats itself. The issue appears to maintain it's schedule independently of restarting the database. Statspack reports do not show an increase in commits or executions or any new sql running during the time the issue is occuring. We have two production environments both running identicle applications with similar usage and we do not see the issue on the other system. I am leaning towards this being a hardware issue, but the 4 hour interval regardless of load on the database has me baffled. If it were a disk or controller cache issue one would expect to see the interval change with database load.
I cycle my redo logs and archive them just fine with log file switches every 15-20 minutes. Even during this unusally long and high session of log file sync waits I can see that the redo log files are still switching and are being archived.
The redo logs are on a RAID 10, we have 4 redo logs at 1 GB each.
I've run statspack reports on hourly intervals around this event:
Top 5 Wait Events
~~~~~~~~~~~~~~~~~ Wait % Total
Event Waits Time (cs) Wt Time
log file sync 756,729 2,538,034 88.47
db file sequential read 208,851 153,276 5.34
log file parallel write 636,648 129,981 4.53
enqueue 810 21,423 .75
log file sequential read 65,540 14,480 .50
And here is a sample while not encountering the issue:
Top 5 Wait Events
~~~~~~~~~~~~~~~~~ Wait % Total
Event Waits Time (cs) Wt Time
log file sync 953,037 195,513 53.43
log file parallel write 875,783 83,119 22.72
db file sequential read 221,815 63,944 17.48
log file sequential read 98,310 18,848 5.15
db file scattered read 67,584 2,427 .66
Yes I know I am already tight on I/O for my redo even during normal operations yet, my redo and archiving works just fine for 3 hours and 15 minutes (11 to 15 log file switches). These normal switches result in a log file sync wait of about 5000 ms for about 45 seconds while the 1GB redo log is being written and then archived.
I welcome any and all feedback.

acyoung1Lee,
log_buffer = 1048576 we use a standard of 1 MB for our buffer cache, we've not altered the setting. It is my understanding that Oracle typically recommends that you not exceed 1MB for the log_buffer, stating that a larger buffer normally does not increase performance.
I would agree that tuning the log_buffer parameter may be a place to consider; however, this issue last for ~45 minutes once every 4 hours regardless of database load. So for 3 hours and 15 minutes during both peak usage and low usage the buffer cache, redo log and archival processes run just fine.
A bit more information from statspack reports:
Here is a sample while the issue is occuring.

What's a good speaker to use in an iOS Garageband Jam session ?
What's a good speaker to use in an iOS Garageband Jam session ?
Really I want to connect a few iOs devices together to create a loud sound...
Any thoughts....Snapping with the iPhone is great when you out and want to catch something, but the care needed to capture a sheet of music requires focus, lack of keystoning (that's the big one - you're really going to have that lens absolutely perpendicular to the centre point of the sheet, and ignore any distortion towards the edges?).
Sorry - if you want to reproduce music at a decent level, it has to be a scanner. -
Sessions were still active eventhough Dead lock detected
Hi all,
Yesterday I saw very odd oracle behaviour.When oracle finds Dead lock it should kill those sessions automatically.In my case those two sessions were still trying to run the same update command and were casuing dead locks again and again for 1 Hour.I had to kill those sessions manually to avoid these dea lock.
How can those sessions were still trying eventhough dead lock detected and causing deadlocks.My logfile filled with this dead lock error.When I killed those sesions it end up with snap shot too old error.
Please suggest me
Thankshi
just ROLLBACK or COMMIT any one session. you will out of dead lock.
and one more thing is in dead lock situation the sessions were not terminated
and session wating for releasing locks aquire by another session
try this one if not work plz reply
have a nice time
best luck -
How can I Deny permissions to logon to Remote Desktop Session Host server in powershell script?
I am need of some assistance please. I am a system admin and I am trying to create a script that will assist with the tedious tasks I have to do with disabling a user that no longer works for the company.
I have created a script so far that will reset the users passwords and remove them from all groups (minus domain users).
I am trying to make it where it will deny permissions to logon to Remote Desktop Session Host server as well as give full mailbox permission to the manager in Exchange Server 2010.
I know with Exchange 2010, I will need to add the Powershell snapin. Is there a way for this to be added into the script? I am thinking to add the code:
add-pssnapin Microsoft.exchange.management.powershell.e2010
Is there another way to do this? Any help or recommendations would be much appreciated.
$ou = Get-ADUser -SearchBase "<*OU info here*>" -Filter * |
Set-ADAccountPassword -Reset -NewPassword (ConvertTo-SecureString -AsPlainText "<*Password here*>" -Force)
foreach ($user in $ou) {
$UserDN = $user.DistinguishedName
Get-ADGroup -LDAPFilter "(member=$UserDN)" | foreach-object {
if ($_.name -ne "Domain Users") {remove-adgroupmember -identity $_.name -member $UserDN -Confirm:$False} }Why not just disable the account?Why are you searching an OU foro users when you just want to terminate one user?
You can remotely connect an exchange session and manipulate the mailbox permissions. You do not load a snap-in except on the Exchange server.
$Session=New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri http://<FQDN of Exchange 2013 Client Access server>/PowerShell/
Import-PSSession $Session
# exchange commands here
\_(ツ)_/
We have a checklist we have to go through with the tasks listed. We have to keep to the account enabled until HR changes
the status which is usually 30-90 days depending. Managers sometimes need to access the accounts to retrieve information, etc. We put the users in an OU; once we are given permission from the manager we move forward in the removal. -
Jump in users session with control Server 2008 R2/Windows 7 64 Environment
For two hours I've searched and searched and can't find MY answer. My goal is to jump in and control workstations of my employees (a bunch of old farts that would blank out if they had to do anything to allow me to do this) without the use of VNCs or third
party installs. I'm running Active Dir. This is what I've done WITH THE NETWORK FIREWALL OFF:
installed the mmc Remote Desktop Services Manager
at root level I can only see my sessions automatically
I am remoted into Server 2008 R2 using this snap it to remote into Old Lady #1
I'm a member of:
--Administrators (for domain)
--Domain Admins
--Remote Desktop Users
When I add a computer to the MMC I get: "The computer can't be reached..."
Using GP, I pushed out a policy to the computers in that department the 2 firewall changes necessary
--One about allowing remote access for administration
--One about allowing remote desktop access
----I * the allowed computers until I figure this out, afterwards I will further restrict the "from" computers for security
I'm inches from thinking that what I want can only be done with VNCs or third party apps. I manage beach houses for a living and don't have time to spend like this on helping my old fogies OR walking all over 2 floors to help someone because the printer
is only printing black and white or "my mouse is too fast" or "how do find an email that I deleted"...
Is it possible for me to be all mighty and powerful and take control of my Win7 workstations without them doing anything more than pressing OK when I just in there session?
I don't like third party. I like everything Microsoft unless 100% unavoidable.
Thanks,

Changing VTP Setting and VLANs on CatOS
Greetings to all...
I'm working replacing our old 5505 Core switches running CatOS with 6509s running IOS with a new VLAN structure (VLAN 100 (5505) will be 400 (6509)). The down stream switches are 2948s running CatOS.
My problem is that everytime I either change SC0 or port 2/1 to the new VLAN, I lose my connectivity. Anyone know of a hot command that will change both at the same time?
Thanks,
TomDo I understand that port 2/1 is the uplink port? If so, it should not be difficult. It is not necessary for the management and the trunk native VLAN to be the same, so your should be able to do them in sequence. In fact, I have just changed the management VLAN of our 20 Cat4000 CatOS switches remotely without any problem.
However, you will get cut off at the moment that you change the SC0, but this has nothing to do with the port 2/1 (assuming that the trunk is carrying both old and new management VLANs).
The way I did it was to start with the management station and all the switches on the old management VLAN. On your router (or L3 switch), create the new management VLAN, give its L3 interface a junk IP address, and enable ip proxy-arp on both old and new management VLANs. Note that the router is still routing the old management subnet, say 192.168.2.0/24, to the old management VLAN.
Now pick on an address which will be the router's IP address on the new management VLAN, say 192.168.2.254. Go into your access switch, and configure that address as the default gateway, set ip route default 192.168.2.254. Then reconfigure the SC0 interface to its new VLAN. At that point, your telnet session will get cut off because the management function of the 2948 is on the new VLAN. So, go to your router at set a host route for the access switch to the new VLAN, ip route 192.168.2.2 255.255.255.255 VLAN400. You should now be able telnet to the switch from your management station. Packets from the management station to the switch will be routed by the host route. Packets from the switch to the management station will be routed courtesy of the proxy-arp.
Repeat this for each access switch, and once they are all done you can move your management station and give the router its proper address 192.168.2.254 on the new VLAN. You can then remove the proxy ARP and/or change the native VLAN of the trunks at your leisure. If you are changing the native VLAN of the trunks, do the remote end first ;-).
Hope I have understood your question correctly, and hope this helps.

Oracle 9i Snap shot too old error
Hello All,
We are using Oracle 9i. When I refresh M Views manually they are executing fine.
Initionally while creating M Views. I did a auto refresh for every 4 hours. After a week of sucessfull execution they error out giving snap shot too old error.
Upon my DBA request We have increased UNDO space from 500 MB to 2 GB.
And also removed AUTO refresh of M Views and created a procedure to refresh M View one after the other and scheduled to run 4 times a day.
Logic is to avoid parallel M View refresh.
However, non this helped to resolve snap shot too old error.
Now My DBA is asking increase the space by 2 more GB. I think the issue is some thing else.
Similar jobs are running perfectly in my Dev environment (DATA is almost same 10% varience) with UNDO size 500 MB.
Can you please help me here.
Thanks,
Ravi.There are some questions,
first is about undo parameters, what is the value of undo retention and how many time execute the refresh.
second. Can you modify your undo to autoextend?
third. Who is using the undo?
This can be found in my friend Google:
http://oracledisect.blogspot.com/2008/05/who-is-using-your-undo-space.html
V$UNDOSTAT: histogram-like view that shows statistics for 10-minute intervals.
V$TRANSACTION: present time view providing information on current transactions.
