Logfile switch is not causing checkpoint.
Hi,

Doesn't log switch cause checkpoint ?.

Log switch imply checkpoint but checkpoint does not imply log switch, when you make a log switch it initiate a checkpoint and move to another log file for writing, when a log switch occur every contents within the redo buffer should be written to log file before its reuse though it is already written to log file when it is
1/3 filled
after 3 second
but still it make sure to write alls the contents within cache to disk.Its a slow background process.

Software Update Point Switching is not working for some Clients
Hi there,
I found nothing similar here and I hope this is the right section.
I´m running ConfigMgr 2012 R2 where one of the Site Systems from one of the Primaries is located in an untrusted Forest in a perimeter Network. The Site System there has the MP, SUP and DB Roles. In general it works great. The Systems in that untrusted Forest
get the SCCM Agent pushed, see and can install published Software packages and receive Windows Updates. But there are a few systems where everything works, except Windows Updates.
So I had a deeper look at what is happening and found out that the SUP switching is not working for them. They always try to contact the SUP from the Primary, which they cannot reach (this is intended).
From how I understand SUP switching as described here
http://blogs.technet.com/b/configmgrteam/archive/2013/03/27/software-update-points-in-cm2012sp1.aspx#pi140062=1
the Windows Update Agent tries to connect to a SUP every 30 minutes and after 4 failed attempts he will try to connect to the next one until he finds one which works.
As I said before, this seems to work for most systems in the untrusted forest, but some do not make any intentions to switch the SUP.
So my next step was to find out from where the Update Agent can get the information of the available SUPs. I think they either don´t receive the information that other SUPs exist, or if the Information is there, they don´t realize that there´s an error and
make no attempt to switch.
I used the System Center Support Center to gather all Information from some of the systems with that problems (Log Files, WMI information, registry information, policies etc.) but I cannot find where SCCM or the Update Agent store the information which SUPs
are available in my environment.
I´m sure the problem is on the Systems which fail to connect to the right SUP and not in the SCCM infrastructure itself, because for most of the systems everything is working just perfect. Unfortunately in the Blog Post above there´s also no information
where this information is stored and how it is obtained by the clients. In the comments there´s even one post which describes the same problem I have here, but there was no answer. I hope someone can point me into the right direction, because I´m stuck currently.
Things I tried additionally to all the log file / WMI / registry sniffing:
Removing the Software Distribution Folder and restarting the Windows Update Agent
Removing the WindowsUpdate Registry folder in the HKLM\SOFTWARE\Policies\Windows section in the Registry and restarting the Windows Update Agent.
Tried to reset the WUAgent with wuauclt /Resetauthorization additionally to the steps above.
I also tried to manually set the WUServer and WUStatusServer Keys in the registry to the new Server, but as soon as the next Update Scan cycle runs, the value is set back to the URL of the Primary Sites SUP
Is someone having additional ideas? It seems to me older systems are more affected (which were configured for a standard WSUS before SCCM 2012 was deployed) than newer ones which were installed when SCCM was in place already. But I don´t know what else to
"reset" on those machines without reinstalling them.Thank you very much for your response. I must have missed that one by looking through numerous Logfiles. In this, there´s indeed a list of all available SUPs. So according to the LocationServices.log the machine should have a choice.
The WMI Key however, contains just one entry and this is the URL of the Primaries SUP which is not reachable in the untrusted forest. Is it OK that the WMI entry includes only one entry? If yes, what process is putting the results from the LocationServices
into WMI? It seems like the Windows Update Agent is feeded from the WMI Key then. If this is the case my problems seems to be the "communication path" between these two components.
Is this the job from the SCCM Agent, the Windows Update Agent or maybe some third component I´m not aware of? I wonder how I can fix this. -
Good day all,
I have been looking at the -logfile switch when invoking dgmgrl to log out the output of some commands.
I want to try and log out things like show config and show database to be mailed to our help desk to allow them to monitor that the standby db is working.
Every time I invoke dgmgrl -logfile <File Name> I can't find the file it should be creating.
I have read the documentation and it does not say that the logfile is put in a different location but it does infer that you need an observer and the -logfile switch (command line switch not redo log switch) can only be used when logging onto an observer.
Is this true?
Is the only way to log these commands to use an external command like script?
Thanks
SteveThanks Mseberg.
From what I can see, the observer is utilised to monitor and effect automatic failover when in Max Availability mode.
We are running in Max Performance and do failover by hand when the decision is taken.
It looks like the -logfile switch can only be used with the observer as using this switch without an observer no log file is produced which is a shame as it would be very useful to be able to log out show configuration and show database by a job and then e-mail it rather than having to log onto each DG configuration to ensure it is still functioning.
Is my understanding correct?
If so then we won't be able to do what I was hoping other than using a linux/unix script command as we won't be using the observer.
Or can the observer be used but actually switch off the fast_start_failover stuff just so we can use it to monitor the configuration?
I hope I am making sense. -

Location switching does not work on Vista
Hi, my location switching does not work. I have reinstalled my Access Connection several time but still does not work. I have several profiles and I need to switch manually depending on my location profile. My Access Connetion however seem to know the right profile (dot next to the profile indicate it picked up the right wireless signal) but never connect to the profile
Is there any Vista feature that is controlling the access as well? Do I need to disable? I remember the older version of Access Connection will ask to disaable some windows services when using Access connection.
My Config is
- R61
- Intel(R) Wireless WiFi Link 4965AG. File Version 11.1.1.16
- OS Vista 32 Business - with up to date patches
- Access Connection 4.42 for Vista Build 7RCN38WW

I found this (TS3579: If the wrong date or time is displayed in some apps on your Mac Learn about If the wrong date or time is displayed in some apps on your Mac) useful because I did not know about the effect of typing in data and that you could only drag to rearrange the data. I had typed in data before and this had caused problems but restoring defaults did not cause correct dates to show up in Finder.
It sounds like there are a couple things going on here. First check if you have a successful install of SQL Server, then we'll figure out the connection issues.
Can you launch SQL Server Configuration Manager and check for SQL Server (MSSQLSERVER) if default instance or SQL Server (other name) if you've configured your instance as a named instance. Once you find this, make sure the service is started.
If not started, try to start it and see if it throws an error. If you get an error, post the error message your hitting. If the service starts, you can then launch SSMS and try to connect. If you have a default instance, you can use the machine
name in the connection dialog. Ex: "COWBOYS" where Cowboys is the machine name. However, if you named the SQL Server instance during install, you'll need to connect using the machine\instance format. Ex: COWBOYS\Romo (where Romo
is the instance name you set during install).
You can also look at the summary.txt file in the SQL Server setup error logs to see what happened on the most recent install. Past install history is archived in the log folder if you need to dig those up to help troubleshoot, but the most
recent one may help get to the bottom of it if there is an issue with setup detecting a prior instance that needs to be repaired.

My iphone 4 has suddenly ceased to operate with a full battery and switch will not display slider. How can I reactivate it? Is the memory gone? Will T Mobile replace the memory or the phone if necessary?
Hello,
If you're in a country where there's an apple shop (unfortunately not mine), go check it and ask the employee about it: he's gonna check your Iphone on a "device"
I've got an iphone 5 and it's working very well with me but I have to admit that its battery lasts (slower) than my Ipad 2.
Still i can help with some tips that may improve your iohone's battery by an hour in addition (hopefully):
- close all apps by multitasking....
- do NOT keep the brightness to the max
Believe me you're gonna regret changing your phone to a samsung
Hope i've helped and sorry for my bad english (has english as 3rd language) -
KM Switch (Video not needed) or software solution
*Short version* - I need a USB switch that will allow me to share just my keyboard and mouse with my 3 PCs. Anyone know of one that works good and has that "sniffing" feature as to reduce any USB delay. I tried a 4 port Belkin USB switch, but it wasn't good. I want a KM only hardware or software solution that is convenient and supports my mouse's back button and does not have scrolling issues.
Thanks for any input...
*More details* - I have a monitor on my mac and a monitor on my xp machine. I don't want to spend hundreds of dollars on a 4 port, DVI, USB KVM switch. I already have a 4 port PS/2 KVM switch and I am using it for my windows PCs. I am only using the video from it to switch between the windows PCs. I just want to be able to use my Mac keyboard and mouse (logitech) on all my PCs. I first tried using RDP, but I was not able to use the back button and had some scrolling issues that were unacceptable. Next I decided I would buy a Belkin 4 port USB switch. I just returned it because besides being a bad solution, the mouse locked up continuously. I then tried using KMremoteControl, but I am having trouble getting the license to activate (I emailed the company). From what I understand it is a free program, but they still sell it? Not sure what thats all about, but that also does not allow the back function on my mouse. Basically the best thing is for me to unplug the keyboard and plug it into each computer as I use it. Does anyone know of a good switch, so I don't have to do that? One that is compatible with windows of coarse and has a simple method of switching. The Mac usb extension cable was also incompatible with the Belking switch. Not sure why apple makes such a short cable in the first place.
For anyone who has read this, thank you, I appreciate it.I have figured out why KMremote was not activating. I installed wireshark to sniff the network and I noticed some DNS issues during the activation process. For some reason it didnt like using my Linksys router as a DNS forwarder. I added the direct comcast DNS entries and it now works. I still dont have the back button on my mouse, but this is the best solution.
Thanks and hopefully this can help someone else. -
When I plug in my Lacie Firewire 800 drive into my Mid-2009 Macbook Pro running Mountain Lion - 10.8.2, it causes certain apps to crash. Chrome will immediately crash when I open it, so will DVD player. It's only when I plug in my Firewire 800 drive, USB does not cause issues. What's the deal?
I've restarted, verfied the disk, repaired permissions, smc reset.. don't know what else to do..Contact Lacie since it's their product you are having issues with.

Fabric with two Nexus-5548 and a brocade switch does not get fabric updates

Workflow not starting and RFC status is 'User Switch Is Not Possible'
Hi All,
I am using ABAP classes to raise an event that triggers the workflow.
When I am executing the workflow from SWUS or raising event from SWUE or SE24, the workflow is starting fine.
But when I am raising the event from a Webdynpro application, the same event is raised, but the workflow is not getting triggerred.
I could see a record in SWEL, but the workitem is not created.
In SWEL, it is showing the RFC status as 'User Switch Is Not Possible'.
When I go to SM58, I am able to re-execute the failed transaction and this time the workflow is getting triggered.
The same workflow is working fine in D env. but not in T env.
The event linkages are all same and I also used the COMMIT WORK statement after raising the event.
Another problem is the RFC status is sometimes set to SYSFAIL and sometimes as 'System overloaded, repeat immediately by batch' other than 'User Switch Is Not Possible'.
Please help.
Thanks,
Cay.Hi,
call function module AUTHORITY_CHECK_RFC explicitly before a remote call to be able to treat a possible exception. If the authorization exists, the function module does not return an explicit result but, like all successfully executed function modules, sets sy-subrc to 0. If sy-subrc is not equal to zero then it could be the problem with the user authorization.
I also think it could alos possible because of your Host name check whether any changes are done to host name.

Mac InDesign CS5.5: can someone please check if variables do not cause crash when copied
Hello
There is a bug in Mac InDesign CS4 and CS5 which causes InDesign to crash if text containing a variable is copied. I am hoping this bug is fixed in CS5.5.
So can someone with Mac CS5.5 try this for me and report back:
1. create a variable, or use one already created by Adobe
2. insert it into some text
3. copy the text
4a. try pasting it into another part of the same document
4b. try pasting it into an external document, for example an Excel file.
Hopefully it won't crash and you will be able to tell me whether it is fixed or not! If variables do not cause InDesign to crash when copied then it might be worthwhile for me to upgrade to CS5.5.These problems are rarely easy to debug.
It appears from your crash report:
5 com.adobe.PDFL 0x216ef8e3 PDDocGetMergedXAPKeywords + 86221
That the problem is in the Adobe PDF Library (not surprising, this is what reads PDF files) when getting "merged XAP keywords," whatever those are.
I believe the XAP: metadata has been superceded by XMP metadata, so this suggests your PDF files have corrupt XMP metadata, or XMP metadata that InDesign cannot deal with.
You might try running some of the preflights and fixups in Acrobat that relate to analysis of XMP metadata,
or simply removing XMP Metadata from the PDF entirely, again in Acrobat.
It sounds like this is a genuine InDesign bug (even if your PDF file was damaged, it should not crash ID!), so you should open a case with Adobe Support and get them to file a bug (http://adobe.com/go/supportportal). Optimistically, such a bug is unlikely to be fixed in time for CS6, so don't expect miracles. Think of it as making sure your bug doesn't hurt other people two years from now. -
My off switch is not working on my iphone 5
Make an appointment at an Apple Store and have them evaluate the device and possibly replace it if still under warranty.
In the meantime, you can enable AssistiveTouch which floats a virtual button on-screen which can mimic all hardware buttons on the device:
Settings>General>Accessibility>AssistiveTouch: turn ON
*Note* If you power off the device using the AssistiveTouch panel (tap the on-screen AssistiveTouch button, Device>Lock Screen (tap and hold to power off)), you will NOT be able to power on the device if your Sleep/Wake (power) button is not functioning. You will need to connect the powered off device either to a PC's USB port or an external charger to power the device back on.
