VISA Set I/O Buffer Size fails with all but one value on Linux RT

I was unable to initialize a serial port on a cRIO-9030 using a code that works fine on VxWorks and Windows, when I tracked it down to this somewhat strange behaviour;
If you call VISA Set I/O Buffer Size on Linux RT (at least on the 9030 device) you will get error code 1073676424 for all size values other than 0.
That is a bit strange (what will the buffer size be then I might add...), but something even uglier is that if you leave the function's buffer size unwire, you will also get the error (because the function's default is 4096).
MTO

Under the hood VISA is using the POSIX serial interface for Mac OS X (same as for Linux and Solaris). This interface does not support changing the buffer size. Hence, the buffer size is fixed to the internal OS buffer size. The only thing that changing the buffer size will do (for the out buffer) is to have VISA not flush the data after every write. This is a limitation in the serial API for Mac OS X. Therefore, VISA reports a warning.

Warning 1073676424 from VISA Set I/O Buffer Size.vi on a serial port

I am porting an application from LabVIEW 6.1 on Windows to LabVIEW 7 on OS X (Mac). It was very painless except some GUI modifications.
The application involves 30 KB data from a instrument through a RS232 serial port. I found the application misses data whenever the computer is busy. The problem came down to the unchanged buffer size.
Attempt to change the buffer size of a serial port with "VISA Set I/O Buffer Size.vi" fails with a warning of 1073676424 (The specified I/O buffer is not supported). Even the example vi from NI web site "Advanced _Serial_Write_and_Read.vi" has the same warning.
I wonder what I am missing.

Reset your iPad and see if that helps.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

I need help setting up my daughters iPod. She has been using her iPod touch for 6 months using my ID. This caused a problem now that she is a bit more savvy and has learnt to message and FaceTime. I get her calls and she gets mine. I have set her up her own ID with iCloud but when I go to settings for FaceTime and messaging I can't erase my ID. So the problem is not really solved. She will have to access iTunes through me as she doesn't know my password and any games etc have to pass the mummy test. Can anyone help?

Thanks. I have my iPad on my lap and her iPod in my hand. We can FaceTime each other but it won't let either of us message each other. I know mine is activated as I use it frequently. I have activated hers as well. Maybe I will put it in the too hard basket for tonight, sleep on it and try again tomorrow.

I find using the iPhone / iPod size virtual keypad much easier to use with a stylus...as when an iPhone app is installed on the iPad. Anyway to use the iPhone size keypad with all apps?

I don't want the keyboard to become bigger. Wish there was a way to always have the iPhone sized keypad available for use with any app. When typing with fingers or stylus, the distance between keystrokes is SO much shorter and efficent on the iPhone keypad vs the "full size" iPad keyboard.
I've heard that there will be some keyboard options when the new IOS comes out...wish this was one of them.
Haven't looked yet, but is there a place you can recommend things such as this to Apple?
Thanks.

PUT Blobs of size greater than 5.5MB fail with HTTPS but not HTTP

I have written a Cygwin app that uploads (using the REST API PUT operation) Block Blobs to my Azure storage account, and it works well for different size blobs when using HTTP. However, use of SSL (i.e. PUT using HTTPS) fails for Blobs greater than 5.5MB.
Blobs less than 5.5MB upload correctly. Anything greater and I find that the TCP session (as seen by Wireshark) reports a dwindling window size that goes to 0 once the aforementioned number of bytes have been transferred. The failure is very repeatable and
consistent. As a point of reference, PUT operations against my Google/AWS/HP accounts work fine when using HTTPS for various object sizes, which suggests my problem is not in my client but specific to the HTTPS implementation on the MSAZURE storage servers.
If I upload the 5.5MB blob as two separate uploads of 4MB and 1.5MB followed by a PUT Block List, the operation succeeds as long as the two uploads used
separate HTTPS sessions. Notice the emphasis on separate. That same operation fails if I attempt to maintain an HTTPS session across both uploads. This is another data point that seems to suggest that the Storage
server has a problem
Any ideas on why I might be seeing this odd behavior that appears very specific to MS Azure HTTPS, but is not seen when used against AWS/Google/HP cloud storage servers?

Hi,
I'm getting this problem also when trying to upload blobs > 5.5mb using the Azure PHP SDK with HTTPS.
There is no way I can find to get a blob > 5.5mb to upload, unless you use http, rather than https, which is not a good solution.
I've written my own scripts to use the HTTP_Request2 library, to send the request as a test, and it fails with that also when using the 'socket' method.
However, if I write a script using the PHP Curl extension directly, then it works fine, and blobs > 5.5mb get uploaded.
It seems to be irrelevant which method is used, uploading in 1 go, or using smaller chunks, the PHP SDK seems broken.
Also, I think I've found another bug in the SDK, when you do the smaller chunks, the assigning of the BlockID is not correct.
In: WindowsAzure/Blob/BlobRestProxy.php
Line: $block->setBlockId(base64_encode(str_pad($counter++, '0', 6)));
That is incorrect usage of the str_pad function, and if you upload a huge blob that needs splitting, then the blockIDs will after a while become a different length and therefore fail.
It should be: str_pad($counter++, 6, '0',STR_PAD_LEFT);
I also think there is 1 too many base64_encodes() in there, as I think its being done twice, once in that line, and then again within the createBlobBlock() just before the send() for a 2nd time.
Can someone please advice, when this/these bug(s) will be fixed in the PHP SDK, as at the moment its useless to me as I cant upload things securely.

Creating Open Directory Replica fails with Server Admin Error Value 1127

Hallo,
I have seen a lot of similar threads here and they were helpful up to a certain point, but in the end, they did not solve my problem.
Currently, it comes down to this. The Server Admin Error message ist really meaningless and I could not find a single for the error value on the whole wide web. As such, I switched to the command line versions of the tools involved to geht more meaningful results. It worked. Specifically, creating a replica of an openldap master means using slapconfig.
When executing
slapconfig -createreplica master.ourdomain.com diradmin
as root on the prospective replica machine, I get the following error message:
ssh command failed with status 127
That command is not allowed with the root account via public key authentication.
That makes perfect sense to me, but how is it meant to work then?
Executing slapconfig as admin tells me that this tool is to be executed as root. On the other hand, root login via ssh is not allowed in Mac OS X by default, which seems fine to me. I even changed /etc/sshd_config on the Open Directory Master machine to "PermitRootLogin yes". However, neither reloading ssh using launchctl nor restarting the whole server made this setting operational. Trying to login from command line as root still tells me:
root login is not permitted to this machine via public key authentication.
While this is the current state where I need help urgently, I changed some other things before. I tell about to exclude these issues as possible reason of failure. I got this message for quite a while:
Replica Setup failed : This machine does not have a valid computer name
I was sure, this machine meant the target machine, the open directory master, because the domain had changed there once before I had taken over responsibility as an admin in this environment. And in fact, changeip disguised an issue there. The command proposed by changeip to fix the situation did not seem appropriate because this machine is multihomed with a public and a private IP adress. Proper name resolution is available for both interfaces including reverse lookup. I dont like this setup, but it was the only way to get mail service running smoothly. Running changeip on the machine itself using these arguments
changeip /LDAPv3/127.0.0.1 internalIP internalIP old.ours.com current.ours.com
reported success in updating password server, open directory, both interfaces, hostconfig (which in fact did not change) and samba. It reported an issue with kadmin which is related to Kerberos (we dont use Kerberos yet).
Changing the hostname of the server using changeip did not solve the issue. I then found the hint to check with scutil. This showed that the Hostname was not set on the prospective replica machine. (A question aside: in how many place is the hostname stored? The traditional /etc/hostname has gone, but seems to be replaces with several other configuration files and databases. I cant see this as an advantage). Setting the hostname using scutil worked fine. However, it did not solve the problem either. At least, slapconfig now started to complain about not being able to log in as root instead of failing from the start.
I also checked all log files on bboth machines that might have to do with openldap, as there are /var/log/slapd.log, /var/log/system.log and /Library/Log/slapconfig.log. I also checked the log of th layer on top of openldap which is /Library/Log/DirectoryService.server.log. None of them revealed anything noticeable beside a lot of of entries that I have googled in the last few hours and which all dont seem to be associated with the problem in question.
I will take a break now, but I have to fix this until tomorrow and I hope to get the ultimate hint from you, dear reader.
Thanks and bye, Christian Völker

ssh command failed with status 127
That command is not allowed with the root account via public key authentication.
Initial OD replication takes place via 'ssh'. If you have 'sshd' configured on the OD Master to authenticate with public keys then the OD replica will not be able to communicate with the OD Master via 'ssh'. You must configure the OD Master to use 'ssh' with password authentication and root login enabled.
Demote the replica back to standalone. Stop any services that you may have running on the primary network interface. Then stop any services that you may have running on the secondary network interface. In the 'Network' System Prefpane remove the IP number from the secondary interface then deactivate the secondary network interface.
Assign the private IP address and hostname that you wish to use for the replica to the primary network interface. Assign the 'public' IP number to the secondary interface. Check the DNS to see that the IP address and hostname for the primary network interface resolve both forward and reverse for the hostname of the replica that you have chosen. If it does not, fix your DNS before proceeding.
In the 'Sharing' System Prefpane, change the name of the machine to the hostname (server.domain.tld) of the replica that you have chosen. Then use 'changeip -checkhostname' to see if the IP/hostname matches. Fix it if it doesn't.
Then configure the /etc/sshd_config file on the OD master like this:
\# Authentication:
PermitRootLogin yes
PasswordAuthentication yes
PubkeyAuthentication no
and the /etc/ssh_config file on the OD replica like this:
PasswordAuthentication yes
PubkeyAuthentication no
Then from the OD replica as the 'root' user issue:
slapconfig -createreplica <ODMasterIPorFQDN> <diradmin user>
Make sure that the 'diradmin' user's password contains only alpha-numeric characters -no 'option-characters' or symbols, change it first if it does. Once the process completes, reactivate the secondary interface for the 'public' IP and check the configuration of services that will be using that IP, then start your other services. Secure the 'ssh' service on both machines to disable password authentication and 'root' logins.

Large XML Publisher reports fail with client-error-request-value-too-long

The linux sysadmins set the cups max_request_size at 10 MB, which was causing this error. Once the restriction was lifted, the reports ran without error.

Can't set up wireless connection for HP C4385 All-In-One with Windows 7.

Hi guys,
I just got a new laptop with Windows 7 64 bit. I already had an HP C4385 All-In-One that I was using with my last computer. I have also just set up a new wireless network because I got a new cable provider. So basically I needed to do everything from the beginning.
When I inserted the setup CD and ran the setup program, it said I couldn't continue because my OS was not supported. I went to the HP website and found the solution, which was to plug the printer in via USB and let Windows Update find the latest driver. Ok, that's fine, the printer works now when the USB cord is plugged in.
To set up the wireless connection, the instruction manual says I need to do it through the network setup wizard p on the CD. But that brings me back to my original problem-- the setup CD won't work because it doesn't recognise Windows 7.
So my question is-- how can I update the network settings (SSID and key) on the printer without the network setup wizard?
Thanks for any help, this is really driving me crazy!

Creation of a Table Type value set with 'ALL' as one of the value

Gurus,
My requirement is to create [table type]value set which would show the [LOV]values in parameter of Conc Progr .
So far we have three such values to chose from ,they are, 'Frozen', 'Pending' and 'Testing'. I achieved it.
My question is ,
if user wants to choose 'ALL' three values , how shall I accommodate it in this table type value set?
Giving fourth option as ALL, which would eventually select 'ALL' three values 'Frozen', 'Pending' and 'Testing'.
thanks in advance.

You can't have UNION in the value set.
Try creating a view, which is having UNION with ALL.

DB13 BRBackup fails with br0227e, but plenty of space.

Hi: We use DB13 to schedule brbackup as disk backup to our DataDomain DDR (Deduplication device). However just recently the device filled to 60%.
Brbackup checks the raw space on the device, not the space available considering the great compression we will acheive, and it fails with a BR0227e. Note 17131 says to run BRbackup with "option -q" which will only issue a warning when space is an issue. I'd like to do that using DB13 to schedule the backup, but I can't determine how to apply the -q option using DB13. I thought it might be a parameter for init<SID>.SAP, but I don't know how I would apply the parameter in this parameter file.
How do I apply this parameter?
The other option I suppose, is to create a brbackup script with the option -q and schedule at OS, but I really want to use DB13.

Hi Shashi,
As CDC is built on top of Oracle streams framework, for better responses you can post this ques under {forum:id=70} category.
"ORA-01438: value larger than specified precision allowed for this column" is usually encountered for NUMBER datatype columns. At what level did you check the datatypes? Please confirm if the precision(for NUMBER datatype) are also similar.
Please attach output for the following queries:
select error_message from dba_capture;
select error_number, error_message from dba_apply_error;Please re-validate the data types and then run the same API with remove_ddl = 'Y' option, like this:
exec DBMS_CDC_PUBLISH.ALTER_CHANGE_SET(change_set_name=>'CHANGE_SET_NAME' , recover_after_error=>'Y' , remove_ddl=>'Y');
Hope it helps!
