Amount of time for clients to join a Coherence cluster?

What are some of the factors that affect the amount of time it takes for a client (without local storage) to join the cluster?
We are seeing some tests where the time is a few seconds and other tests where the time is 10's of seconds (up to 30-40 seconds). Would like it to be as deterministic as possible. Any ideas?
Thanks!
Andy

Hi Andy,
We have found that JMX Mbean registration is one factor in startup time, if you have JMX turned on. On joining the cluster, nodes register their MBeans with the MBean servers. If every node has management=all, every node is an MBean server node, whether its needed or not. This can result in an MBean registration storm as every node registers their Mbeans with every other node at startup. Its especially noticable if you have a lot of caches in your cluster. We suggest that only MBean server nodes have the management=all setting to minimize this registration process on startup.

Amount of time for backup with Time Machine

How long should it take to backup my hard drive with Time Machine?
I have an iMac (late 2007). My hard drive has 222.88 GB of data according to Time Machine which is now running. However, it has only backed up 11.47 GB of data since it started almost 7 hours ago. It is backing up to an iOmega 1TB USB 2 partitioned external hard drive. The partion for the backup is 444 GB or so of space.
Can the backup be speeded up? It seems like an it is taking an extradordinary amount of time for the backup.
Thanks for your help.

Can Mac OS Server limit up time for clients

Can Mac OS Server limit up time for clients like a linksys router can? I want to base the time limit on mac addresses.

what exactly do you want to limit?
uptime is the time since the computer has been turned on (total time running), sounds more like you would like to limit internet acccess...??

What's a reasonable amount of time for time machine to "prepare" a hard drive?

I'm trying to put my time machine backup onto a new 3TB external hard drive (my iMac has 500Gb of data). The first external drive said it would take 11 days to back up. After it was running for 3 days I asked an apple genius how long it should take to create this time machine using USB 2.0 and was told it should take no more than 10-11 hours. He informed me that the hard drive was probably bad. I have since purchased a new hard drive and am currently trying to put a time machine backup on it. I started 4 hours ago and the time machine still says it is "preparing backup." At least the first drive was quicker to prepare the backup and gave me a time estimate.
Is this an appropriate amount of time to set up time machine? Is something wrong with my iMac? Can both hard drives be bad out of the box? Am I too impatient?

How do i change the amount of time for slides in a keynote presentation so they are not the same

how do i vary the times for the slides in a keynote presentation, i have 3 videos i need to run longer and the slides I want to run the same

Is this for an unattended presentation?
1. If not, the option would seem to be:
Manually advance the slides containing the videos or
set the transition delay time to the next slide to occur after the video completes using the
Slide > Transition Inspector > Delay (max delay is 600 seconds so if video is longer than 10 minutes, an automatic delay wouldn't work)
2. If you plan this to be unattended your best bet is to compile it in iMovie and have a looping video with all parts timed in the video to your liking.

TS3988 I am in the midst of setting up my new iPad Air, and the process seems to be stuck on "Updating iCloud settings..." What is a reasonable amount of time for this step to take?

I am in the midst of setting up my new iPad Air, and the process seems to be stuck on "Updating iCloud settings..." What is a reasonable time for this step to take?

Shouldn't take more than a few seconds to a minute. If it's stuck, you might want to give Apple support a call to see if they are experiencing unreported server issues. Since your device is new, you are within the 90-day free call support period. You can set up the call here: http://www.apple.com/support/icloud/contact/. You will need your serial number, which is on the box and (I believe) the back of your iPad.

SQL report to get average amount of time for helpdesk closures Pin

Hi, I've been asked to write a report which lists the average time it takes for a helpdesk job to be closed. There isn't a closed date as such, the table column is simply an audit date/time which can be for various tasks.
I need to use this column along with another which is an ID of the action. For example:
User     TaskID   Task    AuditDatetime
Bob        2    Opens job   1/8/2014 11:14:29
Bob        5    Closes job 2/8/2014 10:12:26
Joe        2    Opens job   2/8/2014 11:01:45
Bob        5    Closes job 3/8/2014 11:44:22
My SQL is very rusty, I'm sure the report is technically possible but I can't for the life of me figure out what the SQL is.
I'm aware of the SQL AVG function and also know I may need to GROUP BY the user. I'm thinking some kind of CASE statement perhaps but again I can't think of the SQL to achieve this...
Can anybody please help?

DECLARE @helpDesk TABLE (JobID INT, userName varchar(10), TaskID INT, Task VARCHAR(20), AuditDatetime DATETIME)
INSERT INTO @helpDesk (JobID, userName, TaskID, Task, AuditDatetime)
VALUES
(17, 'Bob', 2, 'Opens job', '8/1/2014 11:14:29'),
(17, 'Bob', 5, 'Closes job', '8/2/2014 10:12:26'),
(22, 'Joe', 2, 'Opens job', '8/2/2014 11:01:45'),
(22, 'Bob', 5, 'Closes job', '8/3/2014 11:44:22'),
(25, 'Bob', 1, 'Opens job', '8/4/2014 11:40:22'),
(25, 'Joe', 3, 'Assigned job', '8/5/2014 11:47:22'),
(25, 'Joe', 5, 'Closes job', '8/5/2014 11:49:22')
SELECT *, DATEDIFF(minute,h2.AuditDatetime,h.AuditDatetime)/60.0 AS hours
FROM @helpDesk h
INNER JOIN @helpDesk h2
ON h.jobID = h2.jobID
AND h2.task = 'opens job '
WHERE h.task = 'Closes Job'
As far as open Jobs go, you could flip it around, like this:
DECLARE @helpDesk TABLE (JobID INT, userName varchar(10), TaskID INT, Task VARCHAR(20), AuditDatetime DATETIME)
INSERT INTO @helpDesk (JobID, userName, TaskID, Task, AuditDatetime)
VALUES
(17, 'Bob', 2, 'Opens job', '8/1/2014 11:14:29'),
(17, 'Bob', 5, 'Closes job', '8/2/2014 10:12:26'),
(22, 'Joe', 2, 'Opens job', '8/2/2014 11:01:45'),
(22, 'Bob', 5, 'Closes job', '8/3/2014 11:44:22'),
(25, 'Bob', 1, 'Opens job', '8/4/2014 11:40:22'),
(25, 'Joe', 3, 'Assigned job', '8/5/2014 11:47:22'),
(25, 'Joe', 5, 'Closes job', '8/5/2014 11:49:22'),
(26, 'Joe', 5, 'Opens job', '8/5/2014 11:49:22')
SELECT *, DATEDIFF(minute,h.AuditDatetime,COALESCE(h2.AuditDatetime,GETDATE()))/60.0 AS hours
FROM @helpDesk h
LEFT OUTER JOIN @helpDesk h2
ON h.jobID = h2.jobID
AND h2.task = 'Closes job '
WHERE h.task = 'Opens Job'
and coalesce the current date in for a close date.

Can I control the amount of time for timed loop

I was curious if it is possible to control how long each frame of the time loop takes or does it have to be constant for each section?

You can change the period for the following iteration.

I'm running Mac OS 10.5.8 & Firefox 9.0.1. It takes a significantly longer amount of time for Firefox to open now. I've always had about 5-6 pin tabs that automatically open, but this was never a problem before. Should I downgrade, or is there a fix? Thx.

Not sure why it takes almost 1-2 minutes for Firefox to fully open and load. It's also not an internet issue, as Safari opens immediately.

Perform the suggestions mentioned in the following articles:
* [[Session Restore#w_configuring-session-restore|Configuring Session Restore]]

Check and tell if its working.

What is the typical amount of time for an iPad to fully charge?

I have a brand new iPad, third generation, WiFi/LTE, 64 GB. It seems to take up to 6-7 hours to fully recharge. I am concerend, only because I had a first generation iPad, and it would charge in 2 1/2 hours. Is this normal?
Thanks

The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

Amount of time for 70GB transfer?

Hi everyone,
Would anyone have a guesstimate on how long it would take to transfer 70GB from an Intel G5 to a Powerbook G4?

Probably the easiest thing for you to do would be to hook the Macs together with a FireWire cable. Put one of them into FireWire Target Disk Mode. Once it's ready, the hard drive of the Mac in Target mode will show up as a removable drive on the other. Copy the files like you would to any other drive.
70GB on a FireWire 400 cable should take roughly 10 minutes.

Same query takes different time for two different users with same privileges

Hi,
Just wanted to know if it is possible for an INSERT query to take different amount of time for two different users for the same volume of data. If so, what could be the reason? I would like to add that we are not executing the query simultaneously. But it is always faster for user1(within 10-20 seconds) and slower for user2(takes around 8-10 minutes).

Show execution plan for each user. I think there is other reasons which you didn't not tell

Installation fine - except the amount of time.

Over all, the installation on my G4 PPC iBook 14" went well. All of my Apps work (so far) including my VPN to my office with Remote Desktop. I was actually surprised.
The only problem I have (so far) is the amount of time for the install.
* disk validation - way too long.
* nearly 3 hours of actual upgrade install.
* spotlight indexing probably will not be done till in the morning.
Well, 1 Mac down and 2 more to go: 12" PPC G4 iBook and PPC MacMini. (yes I got the family pack)

Just skip the verification, especially on your other machines since you now know it's fine. I never wait for that, especially if it would take 3 hours :-O.

Trouble for Client Logging in

I've had this happen a couple of times for clients. I could
be running a sesstion with 16-20 people in it from the same
company. Out of the group, 1-2 people will get hun on the Adobe
Connect "Connecting" screen. It is very hit and miss. One day they
could get in, the next - no luck. This is a big issue for multi day
classes as you could understand.....anyone have any
ideas????

Hi,
I searched around and only find these parameters on Exchange 2013 Mailbox Role. There are no appsettings in the OWA web.config file on Exchange 2010.
Based on my knowledge, OWA logs in Exchange will be mentioned in IIS log. The default path is %SystemDrive%\inetpub\logs\LogFiles. We can check the logs about OWA in these IIS logs.
However, Mailbox Audit Logging feature that allows you to track mailbox owner, delegate, and administrator logons to a mailbox, as well as what actions are taken while the user is logged on. Is this what you need?
Refer to this article about Understanding Mailbox Audit Logging
