Dynamic hostname registration

Hello,
I'm wondering if anyone is aware of any configuration on LAN switches or routers which would allow me to configure a hostname on the device and have it dynamically register to a DNS server? I'm thinking of a function roughly analagous to ipconfig /regsiterdns in Microsoft Windows hosts. This of course would prevent me from having to manually create A records in DNS for all my network devices. Thanks in advance.

The final bits - you need to create a new key file to authenticate your Bonjour updates using the following:
rndc-confgen -a -c /etc/dns/bonjour.key -k com.apple.ServerAdmin.DNS.bonjour.sharedSecret
As you can see above, I stuck my new key in /etc/dns/bonjour.key (no idea where the 'real' place is). You then need to include this file into your /etc/named.conf. Note that the com.apple.ServerAdmin.DNS.bonjour.sharedSecret name is what is put into the relevant zone file by the serveradmin tool.
For you client config, you'd setup like this:
Hostname: <mymachine>.bonjour.example.com
User: com.apple.ServerAdmin.DNS.bonjour.sharedSecret
Password: <whatever secret it generated and put in your bonjour.key file>
Hopefully it's obvious which bits you change for your own configurations.
The only downside I've seen so far with this is that the IP address that gets registered with Bonjour is that of my firewall, which is annoying since I wanted to use this inside a set of VPNed clients (since multicast bonjour didn't seem to work in this situation).

2012 Dynamic Event Registration Array of Controls

In upgrading to LV2012, I have discoverd what may be a bug, or at least an incompatability between 2011 and 2012 with respect dynamic event registration of an array of controls as opposed to individual control references.
This bit of code worked in 2011 but doesn't in 2012, with error 1 generated at the reg events block when run in 2012. I have been in contact with technical support, but haven't yet heard their take on this.
Any thoughts.
Solved!

I've got the bug too -- it appears this bug is present when arrays of control refs are connected to the ConPane. Link to cross-post on LAVA about the original problem. As Patrick@Vision mentions above, one workaround is to ensure that the array of control refs is no longer on the ConPane by collapsing the Register for Events node onto the caller.

Hostname Registration Popup Messages

Started getting these pop up messages every so often with Mavericks & never had them b4.
This computer’s local hostname “<computer name>-iMac-152.local” is already in use on this network. The name has been changed to “ <computer name>-iMac-155.local”.
To change the local hostname, open System Preferences and click Sharing, then click “Edit” and type the name in the Local Hostname field.”
Is this something that has always happened & I’m only now being notified about it?
I did get a new router when I upgraded to Mavericks (Apple Airport Extreme Base Station)
My iMac is hard wired to the router.
Do I have some new issue with my hostname registration after all these years?
System Preferences/Sharing Has for Computer name: “<computer name>iMac- (8)”
I’m posting with brackets & computer name instead of my actual computer’s name.
Originally I named it w/o any number in parentheses after the name. Last month when I checked it had (7) after the name & now has (8).
I have file sharing & printer sharing enabled.

Steve

Thanks for the reply.
1) I only have 1 computer on my local Network, my iMac.
2) I do have other devices connected via WiFi to that network but doubt they access it at the same time; My Smartphone & My Oppo Blu-ray player which is off when I’m using my computer.
3) I don’t know when/if my iMac wakes fron sleep unless I’m siting there.
4) Maybe but which other device?
5) My router is Apple.
6) Re the article, I have not noticed any problems connecting to the Internet & other than that do not attempt to connect to other computers or services. I do receive IP addresses automatically via DHCP
When I set up my Network with my new Apple router, I also set up a Guest Network. No one has yet used it though. (Have a long password so doubt any neighbors have guessed it)
So far it is not a big problem compared to several other Mavericks issues I have had & will be posting soon.

Dynamic Event Registration Error

Hi,
I'm getting to grips with Dynamic events in LabVIEW. However, I've encountered an issue i'm not sure on. When I try to register a cluster of control refs to the Register for Events function I get an error.. See Dynamic Event Registration.vi for small vi highlighting the issue.
Thoughts?

That helped me somewhat, however, I'm still experiencing problems. My events seem to be registering correctly but don't seem to generate when I trigger them. I've configured the event structure to execute should one of the controls in my cluster change value. However, the only event case that get's executed is the timeout case.
I've attached a vi highlighting my problem named Dynamic Event Problem.vi. My real vi is much larger and contains many sub vis so hopefully what I've attached suffices..

JDBC com channel(receiver): dynamic hostname.

Dear,
Imagine the following scenario: a company needs to push data to the pc of it's clients. On the pc of each client a dbase server is installed and the pc of each client will always be online/reachable.
Seeing the large number of clients and the need of easy/flexsible configuration it would not be handy to configure a communication channel per client pc.
Can a jdbc receiver channel be created that allows to configure the hostname of the sql server in a dynamic way (~dynamicconfigurationbean). The xml message will contain all needed data (hostname-userid-password...).
Kind regards
Joris

Hi All,
The conclusion is that dyamic configuration of the receiver jdbc adapter is not yet possible.
Jeol, when we are talking about hundreds of clients, this might be a problem. It is quiet easy to create such a channel, but I wanted to avoid the fact that a creation for each client was needed.
Kind regards
Joris

Dynamic event registration only works for 2 inputs??

Hello,
I have written a routine that traverses for GObjects when the user runs the VI. Based on some information contained within the label of the control, the routine puts a reference to the control in one of 4 arrays. I dynamically register these 4 arrays as part of an event structure.
What I'm finding though is that only objects within the first 2 arrays (rw_event_array and wtc_event_array) ever trigger the event structure. I have used the probes and breakpoints to verify that the other 2 arrays (wo_event_array and other_event_array) both are full of references, yet they never trigger the event.
As a specific example, I have a control that is of type wo. I stepped through my code and saw a reference to the object stored in the "other_event_array" variable. I put a breakpoint on the event structure (which is triggered by a value change on the boolean control), yet it's never triggered.
Why would it be working for 2 of the arrays I input, and not the other 2?
A couple screen caps...here's the place where the arrays are built:
Here's where they are registered:
Just to be clear - it's not that the code inside the event structure "isn't working"...it's that the code inside the event structure is never executed. The breakpoint you see surrounding the event structure never triggers. And again, the first two arrays (rw and wtc) reliably trigger the event structure.
thanks

It's very hard to tell from your limited screenshots where the problem might be. Is there any chance you could upload the VIs instead?
Why are you using local variables for the array references? Given that you must find all the references before you register for events on them, those should be wires. Otherwise there's a possibility of a race condition - the events could be registered before the arrays are filled. That's my best guess as to the problem. You wrote that you probed the array wire and confirmed that there are values in it, but did you probe the wire going into the Register for Events, or only the wire going into the array indicator?
Have you checked if there are any error from the Register for Events node?

Listener dynamic service registration not working

I just set up an Oracle 11.2 instance for the first time and, for some reason the instance would not register with the listener. Any idea for how I would debug this to isolate where the problem is?
For now I have worked around the problem by manaully editing the listener.ora to specify the SID of my instance - this works OK, so I suppose all I want to know is to learn what the problem was to avoid future frustration.
'nstrctl services'was just showing up an instance for the CLRExtProc service and not my new instance.

ADR_BASE_LISTENER = D:\oracleThe listener was created using netca, also at 11.2. According to the doc, I believe that since the listener port is 1521, the LOCAL_LISTENER parameter is correct in being NULL.
I tried alter system register, to make sure it wasnt a delay problem. I also tried bouncing the listener and database.
Thanks for any help.

Dynamic Events Problem

I am fairly new to LabVIEW and I am trying to make a GUI that uses
events to pass messages between three separate event loops, GUI,
Messaging and Logging. GUI controls the state of the other two event
loops by generating control events and using semaphores. While the
messaging semaphore is released by the GUI, Messaging generates
messages and raises them as events. Some message events are handled by
the GUI event loop and others by the Logging event loop. Logging, once
it receives a 'logging ON' control event dynamically registers for
certain message events and logs the message events it handles to file.
When Logging receives a 'logging OFF' control event, it dynamically
unregisters the message events. The logging control events are
registered for the life of the Logging event loop.
I have created a cut-down version of my GUI that exhibits the same
problem. The problem is that after I have turned Logging on and off
once, it no longer responds to logging control events from the GUI.
Even though the GUI is still generating the events. I have looked at
the dynamic logging example in LabVIEW and thought I did the same sort
of thing but I just can't get it to work that way. The only way I got
it working was by creating a clean event registration with all events
each time I want to change the event registration. This is how I have
done it in the example file and it works. But I don't want to use this
method, I don't want to have to re-register the control events each
time I unregister/register message events.
If anyone knows what I'm doing wrong please edit the example vis and post them back.
Notes for the example:
Files are LabVIEW 7.1.1
Just open the front panels for all the vis before running the GUI vi.
The Display vi just does the same thing as the logging vi.
Run the GUI vi and turn on Messaging then turn Logging on and off a few times.
The example works, but if you wire the event registration refnum
input when doing dynamic event registration, Logging will only turn on
and off once, then no longer respond to log control events... what's
going on?

I can't tell you how to solve you problems - without code this is always quite tricky.
But in case you want to log messages to a log file, have a look at this thread

Dynamically build VI using LabVIEW

I'm currently working on an application and I would like to be able to generate VI's using LabVIEW. I remember seeing something like this being used before, so I would like to know how one would go about accomplishing such a feat. The point is that I want to be able to use LabVIEW to generate LabVIEW VI's add some elements to those VI's (controls, functions, etc).
Thanks in advance,

I can not comment on when, but it will become available, someday.
Vision Builder has been doing this for years.
The LV State Diagram Editor (which is wonderful by the way) can obviously edit diagrams and is apparently implemented as a VI!
THe SD Editor (which is great by the way, I love this thing, NO MORE PowerPoint to design) is an incredibly small add-on. This leads me to suspect much of this functionality (i.e. VI's to edit VI's) is already implmented in LV, we just do not have mechanisms to get at it (other than using the very restricted tools mentioned above).
I stongly agree with Wiebe in that this functionality will be rather challenging to master.
It will also be dificuly to support!
Imagine the type of code that would result. here
is one mind bogling possiblity.
Write three VI's
"A.VI" alternately calls "B" and "C".
"B.VI" Executes a "random VI" evaluates the reuslts and clones a modified version of itself as "C.VI" based its evaluation of the random code results and any prior experiments it has performed.
C.VI then duplicates the actions of B.
This could lead to a type of artificial intellegent code that is able to adapt it own algorithm.
What happens if the code after learning and growing decides it does not want to do math anymore and would rather just listen to the same albumn over and over again?
How does a support engineer address that?
The reason I present this extreme case was that this functionaly, when it comes, it will be limited at first (as we see in dynamic event registration).
I seem to remember Rolf Kalbermatter (on Info-LabVIEW) saying something like "Self modifying code is a bad idea and went out style years ago".
Just my thoughts,

Can you post that vi? I am unable to drag and drop it because I have LV2010.
tst wrote:
Static events are fully configured at edit time. They're the ones you know.
Dynamic events are also configured at edit time (because the event structure needs specific data types), but you can play with the event source and whether or not you actually get the event the event at run time.
I am still finding it hard to understand. I get the configured part. THat's coz you have to set up the event structure. What I don't understand is how exactly it becomes dynamic? We still add event cases just like static events. My mind is hurting so much thinking about this
I may not be perfect, but I'm all I got!

Well your image is confusing because you can't run without wiring that reference. But if you did do that then the error comes from the fact that your VI doesn't have a front panel that is open when you register for it. So that control reference doesn't really exists. I mean it exists but you can't reference a control that hasn't been opened.
I think what you'll want to do is open the front panel, but then set it to hidden. Then after the front panel has been opened, and hidden, register for the control event.

Dynamic event multiple loops

I'm trying to see if I can use one Dynamic User Event to control multiple Event Structures. It seems that sometimes once a dynamic event occurs and its "interrupt" is answered by an event case, other VIs only have a short amount of time (<50ms) to reach their event case state for accepting this event otherwise the event seems to be cleared and the other VIs are oblivious that the event even occured.
My Question: Is it possible to use one dynamic event to control multiple Event Structures reliably?
A previous post somewhat speaks of this issue but does not provide a solution or anything insightful.

Thanks to both of you. I found the answer to my question in the second posted link. "the common, correct use case is to have one Event structure per dynamic event registration". I tested this out with the previous attachment by registering the User Event refnum from the ESTOP functional global to another Event Registration node. I then ran this refnum to the top loop. (instread of the top loop sharing the registration refnum with the middle loop). Now I can put a delay of 2000+ ms and not even miss an event. cooool. This will probably NOT be my final solution but its good to know in the future.
Most likely I am going to design each of my main VIs to have a main while loop with a User Event Structure listening for dynamic events. Associated with each of these VIs will be a functional global which contains its User Event Refnum and Registration Refnum. This functional global will act as a gateway into the associated VI for other VIs/Subvis to use. This will follow the "one Event structure per dynamic event registration" rule while keeping my API organized and allowing room for scalability by simply adding more functional globals in the future.
Just putting this info out there for other users.
Thanks again,

Dynamic Event Registration in Reentrant VI

I have a VI running two reentrant Clients. The client uses a subVI (not reentrant) to handle keystrokes. The client passes a VI refnum to the subVI to dynamically register the keydown event. When I run the main VI I receive the FP not open error (1001). I have made the subVI reentrant and did not change the error output, any ideas?

I have attached a modified VI testing the difference between the "This VI" refnum constant and the "This VI's path" -> open refnum constant. The comparison equates both, but the hex values are different. The FP 1001 error still occurs with the Dynamic event registration, the DER requires that the disk FP is open...Why? I don't know.
Odd show...

How to prevent Mac DNS registration with W2K3 DNS

I have a Mac with two ethernet cards. The Mac is bound to a W2K3 AD and presents LAN services via one card (LAN IP). The other card is connected to a non-routed separate network used for other purposes (Private IP).
The Mac registers its forward lookup A record in the AD DNS twice, once with the wanted LAN IP address and once with the unwanted Private IP.
The Private IP address is not reachable by clients so I don't want it to register. Because of the round robin nature of AD DNS, it serves out the wrong IP address to 50% of LAN clients, who then fail to connect.
On Windows, it is possible in the GUI to specifically set a network card's properties not to register with the DNS. On the Mac this setting is absent in the GUI.
I assume there is a setting I can throw from terminal to block dynamic DNS registration for a specific ethernet card, whilst retaining it for the one I want. But I cant find it.
Can anybody point me in the correct direction please?

I think you will have a better chance of seeing your problem solved if you post on the XServe or Server forums.

Time-out issue Always on SQL 2012 Cluster

Currently I'm working on a large deployment of a SharePoint 2013 environment (stretched farm over 2 DC's). We are using a SQL 2012 alwayson multisubnet cluster (each DC has 1 SQL node). During the installation of SharePoint we encountered several connection
time-out errors from the SQL environment. (Exception calling "Open" with "0" argument(s): "Connection Timeout Expired. The timeout period elapsed during the post-login
phase. The connection could have timed out while waiting for server to complete the login process and respond;)
Steps we follow for SharePoint installation are:
Steps to configure SharePoint 2013 on an AlwaysOn Availability group:
1>Create SharePoint databases (with the PowerShell script)
Configure a SQL alias for a consistent SQL instance name.
Create farm on SQL instance/replica 1 (one of the SQL nodes), creating all databases needed (service-apps & web-apps). -->
we are connected directly to 1 SQL node and not connecting to the cluster. Installation server is in same DC as the SQL node.
Stop SharePoint so databases remain static during migration to an AlwaysOn cluster.
2>Move database to AlwaysOn high-availability group.
Restore all the DBs onto SQL replica 2 (with NORECOVERY).
Create AlwaysOn availability group, or use existing
Join the replica 2 databases to availability group.
Create listener.
3>Migrate SharePoint onto AlwaysOn on cluster
Make all SharePoint DB MultiSubnetFailover aware with PowerShell Cmdlet
Reconfigure SQL alias for new listener
àat this point the SharePoint farm is connecting to the SQL cluster (listener of AlwaysOn availability group of the SQL Instance), but we never reached this point so far.
Restart SharePoint services with updated alias.

We are not allow to update/write in the DNS for the multisubnet cluster IP registration, so I think that explains the "failed registration
" error. But can this explains our time-out errors during the SharePoint installation? For the installation we are connection directly to 1 SQL node and not to the SQL
cluster.
Any help is appreciated!

Don't just change the connection timeout on your SharePoint farm. This will just hide the real issue. From your error message, it seems that the DNS record for the Availability Group listener name is not being written. Talk to your AD administrators to validate
if dynamic DNS registration is configured for the DNS servers. If it is, AD will create the DNS entry of the virtual computer object for the Availability Group listener name. The WSFC should also have Create Computer Objects permission in the AD Organizational
Unit where your Availability Group listener name will be created.
On a side note, make sure that you configure a separate SharePoint 2013 farm for your DR environment that will use the content databases joined in the Availability Group. For a stretched farm deployments, latency should be less than 1ms one way as
per this article. And while you can add your admin content and config databases on the Availability Group, asynchronous commit is
not supported.
