Slight static during major memory read/write
It just started doing this. Random static comes on whenever I load a big program like firefox. Stops as soon as firefox is done loading. (not a page, the application)
Does the same thing for other programs like openoffice.
The enterprise manager said the the datafile needs recovery but when I execute the recover I receive:

LabVIEW for memory read/write?
I know LabVIEW has In Port / Out Port vi for the I/O space read /
write. I am wondering if LabVIEW has read/write memory vi? As we know,
Windows 2000/XP do not allow to read/write I/O port and memory
directly from user level(kernel level is OK).May be this post can be of interest to you (I haven't try this myself but it looks like a solution). Hope this helps.

I'm trying to do something that is probably simple but I seem to be missing something. I need to read and write to a memory location (such as 0D00:0000) through LabView. I have downloaded accessHW (Port and Memory Utilities for Windows) but it still doesn't seem to work. I checked and the cvirte.dll and accessHW.dll are loaded when I run LabView (6.0). Any clues?
Try using the read port and write port functions native to LabVIEW. They are under the advanced palette in Port VIs. They are called In Port and Out Port, and read and write to memory locations.
However...I have not been successful in using these very well, probably because I haven't a clue about writing manually to the memory locations.
Good luck, and please let everyone know how you do. -

Hi All,
This question may be outside the scope of Java and this forum (appologies if so). However, I'm trying to read/write some PCI memory locations in either Linux or Windows. I'd like to access these locations via Java. Is there any direct method to do this? Is there an API to access more low level hardware? Currently, I can read/write the memory locations with a program called PciTree. So, I know my PCI device is working, and the basic driver for the PCI device is installed.
If this is not possible in Java, I can try C and study the device driver's functionality.You could write something in C/C++ and then expose methods to Java via JNI. But Java doesn't have built-in support for accessing memory at that level. A third party library may be availble though. Good luck.

Automotive Diagnostic Command Set & kwp2000 Read/Write Memory By Address
I used NI Automotive Diagnostic Command Set 1.0 Read/Write EEPEOM By Address of ECU base VW TP2.0 KWP2000 diagnostic protocol . I used NI example ReadWrite Memory.vi but not successful. I know must use below step.
Description
The usual procedure for getting a security access to the ECU is as follows:
Request a seed from the ECU using RequestSeed.vi with access mode = n.
From the seed, compute a key for the ECU on the host.
Send the key to the ECU using SendKey.vi with access mode = n + 1.
The security access is granted if the ECU validates the key sent. Otherwise, an error is returned.
Who has used NI Automotive Diagnostic Command Set 1.0 and know VW TP2.0 KWP2000 protocol. Please support some suggest and example VI.
ThanksI modify NI example Read/Write Memory lool at attached files.
Now I know how to calculate the key and successful.But sometimes ok and sometimes no ok. The best luck is pass three error.

A Unix Utility (or Scripting) to Do Major Read-Write-Seek Testing on a HD?
I'm wondering if there is a utility in Darwin -- or a (reliable, safe, free) Unix utility I can download -- that will do extensive read-write-seek testing on a hard drive?
Or if not, could I use some kind of scripting commands in Terminal to do something along these lines? Which you'd have to walk me through... : )I don't think this is what you're looking for but at least the suggestion will keep your quest visible if it does nothing else.
smartmontools can monitor hard drives with SMART and can run tests to check the integrity of the disks and (hopefully) warn of imminent failure. The links suggest you want something to test speed/performance, though, so I don't know that smartmontools will be of any use. Since I don't really understand the content of the links well, though, I thought I'd mention this just in case.
smartmontools is available from sourceforge at http://smartmontools.sourceforge.net/. You may have to compile it yourself. I know I compiled it, though you could check for a pre-compiled version. (I might have decided to compile from source for some reason anyway.) The compilation is straightforward, though. Just takes a little time to get it configured the way you want and installed as a daemon if that's how you want to run it. (If you don't want to run it as a daemon, of course, you don't have to spend time getting that bit to work!)

Is it possible to change the read/write permissions on a time machine back-up of iTunes? I'm needing to restore it as my phone deleted half our playlists during sync & am not seeing a way to unlock the permissions. I have the current version unlocked, but can't seem to get the backed-up version. When I click on restore I get a pop-up that says iTunes can't be deleted as it is part of the OS. I'm not even trying to delete, just restore the old version. Any suggestions?
Hmmm, ok I'll give it a shot. I've always had the iTunes sync w/ my phone set up to only load selected playlists to the phone b/c there's a lot more in iTunes than I have room or desire for on my phone. A few months back I started having trouble w/ trying to sync everything & subsequently adding more to the phone than it could hold. The quickest thing at the time was to unclick the sync music option in iTunes so I could still backup the phone to the computer & not have a problem.
When I asked about it during one-to-one session shortly after, they advised me to delete the music off my phone & then re-sync it to the computer, run a backup of the phone & redownload the music to the phone. When I tried this it ended up deleting all my playlists (but not my husband's) from iTunes. Irritating, but I've been rebuilding the playlists since. I had also unclicked sync music again & an Apple person told me the most likely best fix was to delete & reload iTunes completely.
A few days ago I realized I hadn't backed up the phone to the computer in over a month so after deleting & reinstalling iTunes, & w/o changing anything (sync music was STILL unchecked) I ran a backup & my phone went from having 4 GB free space to being 2 GB over capacity due to iTunes trying to download the entire music library to the phone. I made a one-to-one appt again & it was suggested AGAIN that I delete all the music off my phone & then resync it to the computer & redownload the music. We did this (though a few random songs that had previously been purchased somehow remained on the phone), I got home, connected the phone & instead of the music that shows as 'on my device' disappearing from iTunes it just sat there, so, as the guy had told me I MIGHT have to do, I threw all those songs showing in iTunes as being on my phone, in the trash so that it was completely clear.
At this point I checked sync music, made sure the options were 'selected playlists only', checked the ones from my own list that I wanted (I usually have one playlist of comedians from my husband's folder that I also have on the phone, but didn't check it at this point). It uploaded all my stuff just fine, but for whatever reason when it saw that I wasn't uploading that comedy playlist any longer, it not only didn't upload it but proceeded to delete my husband's entire folder of playlists from iTunes. -_- I got on the phone w/ an Apple support person right away but he wasn't able to tell me anything .. basically said we'll have to rebuild everything. I asked about the possibility of using time machine, he said he's not qualified to answer that, so that's when I started looking around online & found, among others, the link I referenced a couple replies ago.
I hope this all makes sense. It's been a long-term issue so I'm trying to go from memory as I figured to begin w/ that I had just made a mistake somewhere, so didn't try to document anything. Now w/ it having happened a 2nd time, I'm not sure if it was 'user error' or something else....... -
I setup some variables in the StationGlobals.ini, which I could then see in my sequence file under Variables:tationGlobals, etc. What I ran into at runtime, however, was that the StationGlobals.ini file had to be read/write. I'm not sure that's a good idea, since I have so many read-only things being read from there, and if it were messed up during a write, I'm not sure how the operators in the field would recover .
If I want a variable to have scope throughout the life of the sequence file, such that (1) Setup/Main/Cleanup can see it (2) I can read/write from/to it (3) I don't have to leave my .seq file unprotected (remove the read-only attribute), what do you recommend?Hi,
If you are writing to the StationGlobals, you will need the file attributes as read/write. The StationGlobals file only gets updated when TestStand shuts down or when if you force a Save Station Globals using the API function.
With the FileGlobals, usually you are changing the Runtime version and therefore you are not changing your Sequence Files. If you are changing the static version of the FileGlobals (DefaultSequenceFileGlobals), then obviously, you will have to have the sequence file with file attribute of read/write.

System Folder errors after I changed all permissions on HD to read & write
Hi,
Two things may have caused probs on my new 2010 iMac (Snow Leopard), and Applecare is shut so I would really appreciate some help as I have urgent work.
1) INCORRECT PERMISSIONS
I have been stupid. I clicked on Macintosh HD and changed all permissions to read & write because I wanted to be sure I could open and edit all documents on other computers.
I ran Disk Utility Repair Permissions from the install disc, but I am still getting system error messages, and my HP printer won't work.
The first message, in Repair Permissions, said: Warning: SUID file System/Library/Cores has been modified and will not be repaired. I have read a support doc on this which says no need to worry but I don't like it and would like to fix this.
More importantly, my HP printer won't work, displays error beside the document in print dialogue box.
Deleting the printer and readding it didn't work, so I downloaded new drivers and tried to install them, which is when I got the second system error message: System extension System/Library/Extensions/BJUSBLoad.kext was installed improperly and cannot be used. Please try reinstalling it or contact product's vendor for an update.
I checked the permissions on the file and they were still wrong despite Repair Permissions, allowing everyone to read & write. So I have now clicked on the entire System folder and changed the permissions to: System read & write, admin read only, everyone read only.
Will this fix it or do I need to do something else, such as check ownership, to make sure all permissions on the computer are now correct?
2) MEMORY STICK SHUT DOWN MY IMAC
Additionally (though I don't think this had anything to do with my problems), I inserted a Sandisk USB memory stick the other day and it immediately shut down the computer. When I inserted it into my Macbook it initially rejected it and gave me a message saying the device wanted too much power so it had ejected it to prevent damage to my computer. When I tried again it was OK. I totally reformatted the stick in case there was something harmful on it, but should I now bin the stick as faulty? Scared to use it again.
3) IS IT BEST TO REINSTALL ENTIRE SOFTWARE?
If I do a reinstall of all the software from the install disc, will it wipe out all my data, such as Mail, documents, bookmarks and other apps?
I would back-up, but if I try and back up files on my external drive it will automatically do a Time Machine back-up and I don't want to do that in case it backs-up all the corrupted files. Otherwise, I wouldn't mind starting again just to be sure all is well.
Expert advice would be very much appreciated.
Thank you
SarahOh, silly really. I was in a hurry and working on docs that I needed to take to the office and open on another computer there.
But when I checked the permissions on the doc it said I could read & write but everyone else was read only.
I thought if I opened it on another machine I'd be stuck with read only access and not be able to work on there. I think I couldn't change it, so I thought to avoid any future problems like that I would change everything on machine!
Yikes. Won't do that again

We have a problem with one of our deployments of Windows Server 2012 Hyper-V with a 2 node cluster connected to a iSCSI SAN.
Our setup:
Hosts - Both run Windows Server 2012 Standard and are clustered.
HP ProLiant G7, 24 GB RAM, 2 teamed NIC dedicated to Virtual Machines and Management, 2 teamed NIC dedicated to iSCSI storage. - This is the primary host and normaly all VMs run on this host.
HP ProLiant G5, 20 GB RAM, 1 NIC dedicated to Virtual Machines and Management, 2 teamed NIC dedicated to iSCSI storage. - This is the secondary host that and is intended to be used in case of failure of the primary host.
We have no antivirus on the hosts and the scheduled ShadowCopy (previous version of files) is switched of.
iSCSI SAN:
QNAP NAS TS-869 Pro, 8 INTEL SSDSA2CW160G3 160 GB i a RAID 5 with a Host Spare. 2 Teamed NIC.
Switch:
DLINK DGS-1210-16 - Both the network cards of the Hosts that are dedicated to the Storage and the Storage itself are connected to the same switch and nothing else is connected to this switch.
Virtual Machines:
3 Windows Server 2012 Standard - 1 DC, 1 FileServer, 1 Application Server.
1 Windows Server 2008 Standard Exchange Server.
All VMs are using dynamic disks (as recommended by Microsoft).
Updates
We have applied the most resent updates to the Hosts, WMs and iSCSI SAN about 3 weeks ago with no change in our problem and we continually update the setup.
Normal operation
Normally this setup works just fine and we see no real difference in speed in startup, file copy and processing speed in LoB applications of this setup compared to a single host with 2 10000 RPM Disks. Normal network speed is 10-200 Mbit, but occasionally
we see speeds up to 400 Mbit/s of combined read/write for instance during file repair
Our Problem
Our problem is that for some reason all of the VMs stops responding or responds very slowly and you can for instance not send CTRL-ALT-DEL to a VM in the Hyper-V console, or for instance start task manager when already logged in.
Symptoms (i.e. this happens, or does not happen, at the same time)
I we look at resource monitor on the host then we see that there is often an extensive read from a VHDX of one of the VMs (40-60 Mbyte/s) and a combined write speed to many files in \HarddiskVolume5\System Volume Information\{<someguid and no file extension>}.
See iamge below.
The combined network speed to the iSCSI SAN is about 500-600 Mbit/s.
When this happens it is usually during and after a VSS ShadowCopy backup, but has also happens during hours where no backup should be running (i.e. during daytime when the backup has finished hours ago according to the log files). There is however
not that extensive writes to the backup file that is created on an external hard drive and this does not seem to happen during all backups (we have manually checked a few times, but it is hard to say since this error does not seem leave any traces in event
viewer).
We cannot find any indication that the VMs themself detect any problem and we see no increase of errors (for example storage related errors) in the eventlog inside the VMs.
The QNAP uses about 50% processing Power on all cores.
We see no dropped packets on the switch.
(I have split the image to save horizontal space).
Unable to recreate the problem / find definitive trigger
We have not succeeded in recreating the problem manually by, for instance, running chkdsk or defrag in VM and Hosts, copy and remove large files to VMs, running CPU and Disk intensive operations inside a VM (for instance scan and repair a database file).
Questions
Why does all VMs stop responding and why is there such intensive Read/Writes to the iSCSI SAN?
Could it be anything in our setup that cannot handle all the read/write requests? For instance the iSCSI SAN, the hosts, etc?
What can we do about this? Should we use MultiPath IO instead of NIC teaming to the SAN, limit bandwith to the SAN, etc?Hi,
> All VMs are using dynamic disks (as recommended by Microsoft).
If this is a testing environment, it’s okay, but if this a production environment, it’s not recommended. Fixed VHDs are recommended for production instead of dynamically expanding or differencing VHDs.
Hyper-V: Dynamic virtual hard disks are not recommended for virtual machines that run server workloads in a production environment
http://technet.microsoft.com/en-us/library/ee941151(v=WS.10).aspx
> This is the primary host and normaly all VMs run on this host.
According to your posting, we know that you have Cluster Shared Volumes in the Hyper-V cluster, but why not distribute your VMs into two Hyper-V hosts.
Use Cluster Shared Volumes in a Windows Server 2012 Failover Cluster
http://technet.microsoft.com/en-us/library/jj612868.aspx
> 2 teamed NIC dedicated to iSCSI storage.
Use Microsoft MultiPath IO (MPIO) to manage multiple paths to iSCSI storage. Microsoft does not support teaming on network adapters that are used to connect to iSCSI-based storage devices. (At least it’s not supported until Windows Server 2008 R2. Although
Windows Server 2012 has built-in network teaming feature, I don’t article which declare that Windows Server 2012 network teaming support iSCSI connection)
Understanding Requirements for Failover Clusters
http://technet.microsoft.com/en-us/library/cc771404.aspx
> I have seen using MPIO suggests using different subnets, is this a requirement for using MPIO
> or is this just a way to make sure that you do not run out of IP adressess?
What I found is: if it is possible, isolate the iSCSI and data networks that reside on the same switch infrastructure through the use of VLANs and separate subnets. Redundant network paths from the server to the storage system via MPIO will maximize availability
and performance. Of course you can set these two NICs in separate subnets, but I don’t think it is necessary.
> Why should it be better to not have dedicated wireing for iSCSI and Management?
It is recommended that the iSCSI SAN network be separated (logically or physically) from the data network workloads. This ‘best practice’ network configuration optimizes performance and reliability.
Check that and modify cluster configuration, monitor it and give us feedback for further troubleshooting.

How do is get back to Read & Write permissions on HDs ?
Hi gang,
I was trying to set up one central folder for 4 iTune users (accounts) in our household.
One of the blogs said put in "Shared" folder and set permissions to "Read & Write". I tried but on "Everybody" is does not offer the "R&W" option, just "Read". They also said to be sure you clicked "Apply to Enclosed Items" in the drop down. Although I could not set "Everyone" to "R&W", I clicked on "Apply to Enclosed Items" and the hard drives clicked for at least 15 minutes.
Afterward I got a pop up that said... System Extension "/System/Library/Extension/ACard6280ATA.kext" was installed improperly and can be used. Try reinstalling. and an OK button to click. I clicked OK and at least 100 more popup appeared, one after the other as I clicked OK. They all had the same basic message except the info after /System/Library/Extension/, it kept changing slightly on each new popup.
The big problem is I now have three of my four internal hard drives locked to my access and all they say custom on the permissions Privilege window. Only my main HD is working, thank God.
How do I get back to Read & Write on Privileges, and on all Hard Drives?
Thanks for any help, I just made the move to MAC but have good background with windows operating system.
GaryThanks for all the reply's, I really appreciate your time. I have Apple Care so I worked with Apple tech last night and today, but they had to pass problem on to their engineers. They did a great job trying to help and spent 2 hours helping me input in code through the Terminal screen. It helped a little, but we still can access drive 2, 3 and 4 due to the global permissions that were changed. All in all, it looks like we have to reinstall the OS on a washed HD.
I found out that the Repair program (Disk Utilities) only repairs permissions that were created after the initial set up. It won't correct original setting and that's what happened when I clicked on "Apply to Enclosed Items" at the root level. Likewise Time machine does not clone the main operating system so a restore would probably not get all the pieces back in their proper places.
I was thinking of doing a reinstall of the whole Mac HD drive (boot drive) with an exact copy I made with Carbon Cloner a month back, but the techs seem to think they will have to work on of the 4 individual HD I have.
Thanks again for the quick responses, I will let you know what happens in a few days.

Lion server file sharing issue with windows API read/write ini file (GetPrivateProfileString)
Hello,
I try to config lion server as file server for a windows application we use at work. All other computers are windows 7 or XP, lion server is the only mac. I choose lion server because it's size, quality and personal love of apple products.
10.7.2 lion server's samba file sharing works almost perfectly with all my windows machines, I can copy, delete, modify any text files or office files without any issue, but the most important windows application for my business doesn't work with samba file sharing. After some digging, I found it is because windows program can't read or write INI file stored on lion share. Windows API GetPrivateProfileString always returns empty if the INI file is store on lion share.
You can download a small application for read/write windows INI file from codeproject.com to test this problem:
http://www.codeproject.com/KB/files/ini.aspx
I can open/edit the in file using any text editor without any problem. The only problem is with those windows APIs. ACL is turned on for my lion share and assigned "delete" rights to samba users.
I install samba3 on the same server; it works perfectly with windows API. My windows program also works. Looks like there is something wrong with lion server's sambax.
I'd prefer to use built-in samba even I have samba3 working. Built-in samba is very immature right now, but considered how young it is, I will give apple some time to make it mature.
Does anyone have same issue or knows how to fix it?
Thanks,
Michael.All the memory is fine. The server rarely if ever goes down when there are only around 10-12 users connected. When there are 20+ users connected and working heavily it goes down often. When I say working heavily, I mean they are transferring huge files to the SAN (100GB+), sometimes 5 at a time per user, and there are a bunch of others who are reading large video files at a minimum of 220MB/sec from the SAN.
Though this worked on Snow Leopard without any issues, Lion just doesn't seem to be able to handle it. The odd thing is, on Snow Leopard there was only a single 1GB ethernet connection to a NAS system, whereas with Lion we have a much more powerful machine with a 6-port 10GB ethernet card and a 4 lane 8GB fiber card to a true SAN. You would think that the newer scenario with Lion would handle far more users with ease.
So far, very disappointing with regards to Lion's file serving performance.
