How to make response time of switch faster?

on 3750, when
1. execute ping -t command from a PC to the switch interface vlan 1 ip address,
2. unplug the cable and plug it again,
it takes about 30 seconds to start pinging again.
i disabled the STP protocol and observed that; with the same procedure, recovering ping replies decreased to 3 seconds.
is there any other tuning that i can configure and make response time even faster?
thank you for helping :)

Hi,
STP convergence is typically the biggest part of host connection delays. Rather than disabling STP, you can configure "spanning-tree portfast" on the port which will achieve the same end.
Beyond that, some of the response time delays are going to be part of MAC address learning, ARP, and the fact that the switch places a low priority on processing ICMP packets. A better test is to ping from another device _through_ the switch rather than to or from the switch.
Here's a good document that covers various commands you can use to mitigate connectivity delays.

How to enhance response time on select?

I'm using ibatis/mySql in my struts application and apparently the response time to receive data (select) is quite long.
I'm referring to a select statement to receive data from 5 diff tables (~6 column each). there are 500 objects (Cars) and it takes around 63 seconds (my computer has 2GB Ram).
can someone advise how to enhance the response time.
thanks

yes, they all have primary keys and indexes.
Do you do the JOIN in the database or are yougetting a ResultSet and then iterating over it to
SELECT the rest? (This will kill you with network
traffic.)
yes I'm using the select with no join.
I'm using abator to auto-generate the sql statements
and therefore I loop on every car'd id and get my
releven info. so basically it's all select after
select and integrate them in the car object. That's the reason then: If your outer select returns N rows, you're doing N network roundtrips to get the rest of the data. It's a certain performance killer.
is there major diff between reading one by one oever
reading everything in one go? meaning right now i do
this:
get list of all car_idNetwork roundtrip #1
iterate through db with car_id and construct a CAR object...Which means one round trip per row. You're dead in the water here, no matter how you optimize the database.
add object to LinkedList move to the next car...Rewrite that query and bring all the data back in one network roundtrip. You'll notice an immediate improvement.

How to view response time for each execution in OEM 12c Cloud Control

Hi All,
I want to view response time of each execution for my SOA composite in OEM 12c Cloud Control. Can anyone tell me how can I achieve that?
Thanks in Advance!!

You should open an SR and support can assist you with it. The only current case where that feature is known to not work is in the case where the Dehydration Store is running on RAC. Otherwise, it should be possible to get it to work. The main thing is that you need to have DB configuration properties (host, port, sid) that have a 3-way string match between the JDBC data source configuration in the WLS server, the JDBC properties you add to the Monitoring Properties of the SOA Infrastructure target, and the connect settings of the Database target in EM that matches to the dehydration DB.
If there isn't a match in all 3, the Dehydration Diagnostics page will not work. But again, to look into your specific setup, you should file an SR and work with support.

How to calculate Response time in HH:MM:SS format ?

Hi,
How can we calculate reponse time in HH:MM:SS format?
I have tried this formula but doesnt really seems to be providing desired output
CAST (FLOOR (TIMESTAMPDIFF (SQL_TSI_HOUR, "Service Request"."Opened Date and Time" , "Service Request"."Closed Date and Time" ) /24) as CHAR) || ' Days, ' || CAST (FLOOR((TIMESTAMPDIFF (SQL_TSI_MINUTE, "Service Request"."Opened Date and Time" , "Service Request"."Closed Date and Time" ) - FLOOR (TIMESTAMPDIFF (SQL_TSI_HOUR, "Service Request"."Opened Date and Time" , "Service Request"."Closed Date and Time" ) /24) *1440)/60) as CHAR) || ' Hours, ' || CAST (TIMESTAMPDIFF(SQL_TSI_MINUTE, "Service Request"."Opened Date and Time" , "Service Request"."Closed Date and Time" ) - (FLOOR (TIMESTAMPDIFF (SQL_TSI_HOUR, "Service Request"."Opened Date and Time" , "Service Request"."Closed Date and Time" ) /24) *1440) - (FLOOR((TIMESTAMPDIFF (SQL_TSI_MINUTE, "Service Request"."Opened Date and Time" , "Service Request"."Closed Date and Time" ) - FLOOR (TIMESTAMPDIFF (SQL_TSI_HOUR, "Service Request"."Opened Date and Time" , "Service Request"."Closed Date and Time" ) /24) *1440)/60)*60) as CHAR) || ' Minutes'
Output for this formula :
Opened Time Closed Time Response Time
16/10/2008 08:50:00 21/10/2008 11:33:21 5 Days, 2 Hours, 43 Minutes
16/10/2008 08:57:00 24/10/2008 15:17:38 8 Days, 6 Hours, 21 Minutes

How to make a Time Machine drive writable?

Hello,
I had an iMac (1TB) and backed it up on a external HD using Time Machine (running Mavericks) Now i want to make changes to the Time Machine HD (I don have the iMac anymore) I have a 500GB MBP, so i cannot restore the backup.
Is there anyway i can make the Time Machine HD writable as i want to delete / move a couple of folders/files from it.
If i can boot from the TM HD also i am ok. Any suggestions would help.
TIA..
Yo

Time Machine deals with something called "snapshots" - and you can delete these snapshots if you are trying to find room on the Time Machine backup disk or make the space of what it consumes smaller.
But not sure what you're trying to do - so just to make it more clear, are you trying to get the size of all the Time Machine backups small enough so that you can do a restore to your new MacBook Pro or are you trying to make room on the Time Machine disk in order to backup the MacBook Pro to the Time Machine disk you now have?
So which scenario are you trying to accomplish?
In any event I would not start removing files on your own from the Time Machine backups - you risk corrupting the whole Time Machine backup database.

How to Make a Timer with Milliseconds

I am trying to create a timer that tracks milliseconds. The reason being is that I want to track key strokes, store them, and later repeat them. In order to repeat each key's input interval accurately, I need to
track amount of time each key is pressed between each other and to do so I plan to record by the millisecond. I won't be storing each millisecond but rather I want to make sure that the Controls.TextType and Timer event can be processed at any moment. From
my observation, I can't go any lower than one second because, realistically, multiple keys can be pressed in less than a second and also I can't recreate one second (accurately) out of milliseconds unless its ticking by one millisecond. As far as I know, I
can use the Timer object but I encountered a limitation. The Timer.Interval only goes as low as 10 milliseconds. I looked at other options and considered using Clock.Millsecond and subtracting two versions of Clock.Millisecond at a millisecond difference but
did not manage to make a working sample.
I also tried using using Program.Delay() but I don't understand how this doesn't measure one millisecond:
gw = 600
gh = 300
GraphicsWindow.Width = gw
GraphicsWindow.Height = gh
GraphicsWindow.KeyDown = onKeyDown
GraphicsWindow.KeyUp = onKeyUp
GraphicsWindow.Left = 0
GraphicsWindow.Top = (Desktop.Height - gh)*0.20
TextWindow.Left = (Desktop.Width - gw)*0.90
TextWindow.Top = (Desktop.Height - gh)*0.20
txtSize = 20
tx = (gw - txtSize)*0.20
ty = (gh - txtSize)*0.50
GraphicsWindow.FontSize = txtSize
GraphicsWindow.DrawText(tx,ty,"CLICK GRAPHICS WINDOW SCREEN THEN")
GraphicsWindow.DrawText(tx,ty+txtSize,"PRESS ENTER TO USE KEY EVENT")
milliSec = 0
sec = 0
print = "True"
While "True"
milliSec = milliSec + 1
If (milliSec > 999) Then
milliSec = 0
sec = sec + 1
TextWindow.WriteLine(sec)
EndIf
If (keyDown["Return"] And print = "True") Then
TextWindow.WriteLine("You pressed at " + sec + ":" + milliSec)
print = "False"
ElseIf (keyDown["Return"] <> "True") Then
print = "True"
EndIf
Program.Delay(1)
EndWhile
Sub onKeyDown
lastKey = GraphicsWindow.LastKey
keyDown[lastKey] = "True"
EndSub
Sub onKeyUp
lastKey = GraphicsWindow.LastKey
keyDown[lastKey] = "False"
EndSub
Why do I suspect my timer isn't accurate? For one, when I count by one (like so one crocodile, two crocodile, etc) it doesn't match up. Also, I've compared it with many online stop watches and it's apparent they run seconds ahead.
My three options:
1) use the Timer object
2) use Clock.Millisecond
3) use Program.Delay
After constant failure and researching, I forgot to consider what is the default rate of a small basic program when its running as a whole and each line. Is it possible to go lower than it? Again the current goal
of my project at the moment is tracking a key stroke and returning the time the user inputted. That's why, I want my timer to move
by one millisecond so I am able to process every action. Any explanation, samples, or guidance would be helpful. Thank you.

Program Code: FRT619
Removing the comments tags (from the last three lines at the bottom of the mainTimer subroutine) will show that I can store time values and rely on the fact that they can be compared. It's no where near completion
but, hypothetically, this will allow me to achieve my main goal: storing time intervals from any key and repeat them at the user's command accurately when the timer restarts. I'm sure I've compromised the timer's accuracy though. What are your thoughts? Do
you see a better way to approach this problem? Also, I wasn't able to display the milliseconds but realized that it may not be necessary since I only need it to process events and store variable accurately. Not to display the precise time. Although, I am open
to any solutions to this minor problem. One more note: I nested the main loop with a small loop that changes run to true when milliseconds is zero. This is used to assure that milliSec has an initial value of zero, which is crucial to store time accurately.
Bug: Timer stops if user holds enter key. Solution: remove program delay in sub routine control, however, user can't hold key and record same key multiple times.
New Solution to bug: implement button and textbox events (allows user input while recording time through PC's clock--in milliseconds).
On a side note, the clock object communicates with the PC's clock, which would mean it's asynchronous from the program and isn't affected by program delay. However, if the PC's clock is ticking by the millisecond(s) and the program stores the time from the
PC's clock and display it with a delay of 1000 milliseconds. The clock object may not be affect but displaying the time will be?

How to improve response time of queries?

Although it looks that that this question relates to Reports but actually the problem is related to SQL.
I have a Catalogue type report which retrieves data and prints. That is not much calculations involved.
It uses six tables.
The data model is such that I have a separate query for each table and then all
these tables are liked thru link tool.
Each table contains 3000 to 9000 rows but one table contains 35000 rows.
The problem is that the report is taking too much time - about 3-1/2 hours while
expectation is that it should take 20 to 40 minutes max.
What can I do to reduce the time it takes to produce report.
I mean should I modify data model to make a single query with equi-join?
A)Specially I want to know what is traffic between client and server when
1) we have multiple quieries and LINK tool is used
2) Single query and equi-join is used
B)Which activity is taking most of time ?
1) Retrieving data from server to client
2) Sorting according to groups (at client) and formating data and saving in file
Pl. guide.
Every body is requested to contribute as per his/her experience and knowledge.
M Tariq

Generally speaking, your server is faster than your PC (if it is not, then you have bigger problems than a slow query), let the server do as much of the work as possible, particularly things like sorting, and grouping. Any calculations that can be pushed off onto the server (e.g. aggregate functions, cola + colb etc.) should be.
A single query will always be faster than multiple queries. Let the server do the linking.
The more rows you return from the server to your PC, the more bytes the network and your PC have to deal with. Network traffic is "expensive", so get the result set as small as possible on the server before sending it back over the network. PC's generally have little RAM and slow disks compared to servers. Large datasets cause swapping on the PC, this is really expensive.
Unless you are running on a terribly underpowered server, I think even 30 - 40 minutes would be slow for the situation you describe.

How to make detection and acquasition processes faster on 6602 board ?

Hi to everybody,
Currently I am using a NI 6602 board. And I am designing my project using VC++ in .NET framework(1.1) .
In my application, I have to wait a digital signal(triggering signal) to go high level to start my acquasition.
At first, I tried to check continuously that incoming digital signal in a seperate thread using ReadSingleSampleSingleLine() fxn (polling). In my application there aren't so much threads , just 3-4 threads, and this thread has the highest priority.
But I recognised that I am missing some acquasition data after I detect the trigger signal.
In more detail the case is: when the trigger signal arrives, I have to capture an incoming byte(which is available on another 8 digital input lines for just 5-6 microseconds).
And the problem is : I can detect the trigger signal by polling but I am missing the incoming byte. I am trying to detect the incoming byte using ReadSingleSamplePortByte() function again by polling. The incoming byte disappears before I manage to read it.
My fist question:
1. Is there anything that you can suggest to make my detection and acquasition process faster?
I tried to use digital edge triggering and change detection events hoping to faster my process. But I got an exception about my board does not support that kind of triggering.
My second question:
2. Is there any way to use digital edge triggering or change detection events in 6602 board?
This is the first time I am using an NI board.
I noticed that 6602 is specialized on timer counter concepts, not on digital I/O concepts. But I don't have a chance to use any other board right now and I have to manage my application using 6602.
any help is welcomed.
thanks in advance.

How to make real-time report per subscriber ( SCE2020)

From the link below Cisco SCA BB SNMP Real Time Monitoring User Guide, 3.1

Thanks in Advance.

SCE platform supports a limited set of variables that may be configured via SNMP (read-write variables). Setting a variable via SNMP (as via the CLI) takes effect immediately and affects only the running-configuration. To make this configuration stored for next reboots (startup-configuration) the user must specify it explicitly via CLI or via SNMP using the Cisco enterprise MIB objects.

How to make a time lapse video in iMovie using a point and shoot camera?

I recorded an approx. 45-minute long video on my Canon point and shoot digital camera, then imported it on to my computer. (The file format is .MOV)
Now I would like to turn this video into a time lapse, of about a minute or two long. I know that iMovie HD has a time lapse feature, but it seems to only be for camcorders?
How can I import this .MOV file and turn it into a time lapse?

Kirk, I think Nancy wants to just take a frame from her video every minute or so, so that the 45 minute video runs for, say, 45 seconds.
I don't think she wants to "speed it up" and make it run at breakneck speed, but wants to put together frames taken at a particular interval ..e.g; one frame per minute.
I'm sure you know how best to do that using QuickTime. Any suggestions?
(..Otherwise, Nancy, choose a point in your video - using iMovie - about one minute into the video and then use 'Create Still Frame' (or ShiftApple'S') and make the new still frame just a few moments long ..repeat through your 45 minute movie. Drag all those 45 stills together and you have a time-lapse movie. You could make each of them one-and-a-half seconds long, and apply a half-second Cross Dissolve between each of them. You'd then have a less "stuttery" and smoother time-lapse video..)

One improvement.. To get a line that is neat, use a bit of Graphics2D
    public void paintComponent(java.awt.Graphics g)
        int w = getSize().width;
        int h = getSize().height;
        // draw a line between (0,0) and (w,h)
        g.setColor(getForeground());
        if (strTop == null)
            strTop = " ";
        if (strBottom == null)
            strBottom = " ";
            java.awt.Graphics2D g2 = (java.awt.Graphics2D)g;
          g2.setRenderingHint(java.awt.RenderingHints.KEY_ANTIALIASING,java.awt.RenderingHints.VALUE_ANTIALIAS_ON);
          //g2.setStroke(new java.awt.BasicStroke(14.0f));
        g.drawLine(0, 0, w, h);
        //the following lines will draw the two strings,
        //one above the top of the line and the above below it.
        g2.drawString(strTop, (w/2)+2, (h/2)-2);
        g2.drawString(strBottom, 2, (h / 2) + 2);
        //the x,y for drawString are only based on assumption.   //do necessary changes to suit ur needs.
    }Then create a TableCellRenderer and set it to the Table Header for ur table's 1st row.....
