Hi,
I am trying to update an Oracle table using dataTableModel. The table does not have any foreign keys. I can correctly display the table. I display it by pages, 10 rows per page. I display four read-only columns of the PK and two Varchar2 updatable columns. The "Update Database" button has the text I grabbed from the "Java Studio Creator Field Guide":
try {
dataTable1Model.commit();
dataTable1Model.execute();
info("Update Successful");
} catch (SQLException e) {
log("Safeguard Prod Bom Update: " + e);
error("Safeguard Prod Bom Update: " + e);
return null;
When I press the button I get the following error:
[Sun][Oracle JDBC Driver]Unable to determine the type of the specified object.
Any help would be greatly appreciated!
Thanks
Slava

Hi Slava,
Does your datatable have any null values? If so that could cause problems... this is a known issue w/editable datatables. The next update should fix that particular problem.

Slave instance can not synchronized with the master for a long time

Hi,
Slave instance can not synchronized with the master for a long time, and the gap of LSNs between slave and master are more and more larger. The transfer bytes per second between master and slave is 118MB/s , upper limit to the ethernet card. Why???
ENVIRONMENT:
1. A network program which we called mcdb is based on BDB 4.8.30. It is used to accept get/set requests and then query data from bdb or save data to bdb.
2. mcdb implements replication with bdb replication manager api. The default start replication policy is DB_REP_ELECTION, rep ack policy is DB_REPMGR_ACKS_ONE_PEER and rep priority is 100.
3. The bdb data files, bdb log files, region files and rep files are all in the same home directory.
4. There are two instances of the mcdb are separately on two standalone servers which has no other programs. These two instances are in one replication group which can elect a master automatically.
5. The master instance is online, which has lots of requests (get, set, delete).
ACTIONS:
1. Start two mcdb instances on two servers and the two instance make a replication group. Slave has already synchronized with the master.
2. Stop the slave for a long time (more than 20 hours).
3. Start the slave instance to synchronize data with master.
RESULT:
1. the gap of LSNs between slave and master are more and more larger.
2. db_stat of master and slave:
master db_stat:
467170     Number of PERM messages not acknowledged

Hi,
Unfortunately, this issue is beyond the level of what is supported over the forum. Performance related issues are extremely complex and require an in-depth understanding of your environment and dedicated support. In a generic sense, you can look at this as a basic queueing problem. You have a server that went down and work is still coming in. When the server gets started it is possible that it may never catch up depending on new work coming in and the rate at processing the old work.
So what would you do in this case --- one thing would be to reduce the new work coming in. In HA terms this would be slowing the master down and you can increase DB_REP_ACK_TIMEOUT for this. Another thing you could do is add fresh servers to help reduce the workload. In HA terms, this would be the equivalent of restarting the client and give it a fresh look at everything. Another thing you could do is replan the system and load balance. In HA terms, it would mean something like take a hot backup of the master and reinit a client from scratch.
If you are interested in getting a dedicated support person working on this concern, please let me know and we can move forward down that path. Just respond to the thread with your email address and I will get in contact with you so we can pursue that approach.
thanks

Can you program a Slave's Node ID or Zone ID using the USB-8476 as the LIN Master?

I am planning on using the USB-8476 LIN interface as the LIN bus Master in an application. The application would require the USB-8476 (Master) to program a Node ID and Zone ID into a slave device that is on the LIN bus. The slave device is a PIC12F1822 mcu + MCP2021 LIN transceiver. After reading through the User/Software Manual for the USB-8476, it does NOT seem possible to assign an ID to a slave device. It seems like you can only communicate with slaves that already have an ID programmed into their memory. The Node/Zone ID terminology is used by our customer and may not conform exactly to the IDs associated with LIN. I am new to the LIN world, so please let me know if you need more information about what I'm trying to accomplish. Can you program a Slave's Node ID or Zone ID using the USB-8476 as the LIN Master?

No need to respond to this topic. The company that builds the slave device has a communications specification that was recently provided to me. I should be able to use the NI USB-8476 and a call to the ncWrite function (NI-CAN Frame API function) to accomplish my goals.

Have 2 airport extreme base stations connected in chain. Airport utility shows slave unit without power. However, power is on slave unit, but status lights do not show up at all. Small green lights at each back port blink. Anyone have any ideas?

Have 2 airport extreme base stations connected in chain. Airport utility shows slave unit without power. However, power is on slave unit, but status lights do not show up at all. Small green lights at each back port blink. Anyone have any ideas?

Unfortunately, you are describing the symptoms of an AirPort Extreme with a failing (or failed) internal power supply.
As a last resort, try a Factory Default Reset on the AirPort Extreme as follows:
Power off the AirPort by pulling the power cord
Wait a minute or two
Hold in the reset button first, and keep holding it in for an additional 8-10 seconds while you simultaneously plug the power back into the AirPort
Release the reset button and allow a full minute for the AirPort to restart
Now try to configure the AirPort again. If you continue to see the same symptoms as before, the AirPort will need to be replaced.

A call for help! Can I make my master my slave?

Hi, friends. I hope these few words find you in good spirits.
I am trying to recover data from about 10 years of my life, and I am hoping one of you will point me in the right direction.
I have an old Power Mac G4 tower (Sawtooth, AGP from about 2000). It has two hard drives: the original, a 10 GB drive in the master position, and a newer 80 GB Seagate in the slave position. The original drive is running OS 9.2.2 and the Seagate is running 10.3 (Panther). Right now it is booting off the original drive. I'd like to boot it off the Seagate, if I can.
First, my question: may I safely and correctly swap the two drives, or just the cables, so that the Seagate drive becomes the 'default' master drive?
Now, the problem, which is knotty and may indicate hard drive failure:
I last booted the computer two years ago, and at that time, both drives worked just fine. Now I am trying to retrieve all my data to a new external drive, and wipe the old Power Mac clean. That data represents a fair bit of my personal life, and I am willing to do just about anything to retrieve it.
Now I cannot get the master drive (OS 9.2.2.) to boot all the way. I booted it with extensions loaded, and I get to the desktop photo and the time (the correct time) in the menu bar, but then the process seems to stop. The hard drive does not appear on the desktop, and although the cursor is not frozen, there is nothing to click on. Then I booted it with extensions off, and again I reached the same place (desktop photo, correct time).
I do not have the startup CD with me. I tried to boot the machine with my OS 10.6 disk (holding down the 'c' key), but the OS 9.2.2 loaded. I tried that twice.
Then I tried to access the original hard drive in target disk mode. The yellow moving 'TDM' symbol on the original computer's screen is visible, but no hard drive icon appears on my laptop (Intel, 2008, 10.6.8). I tried Disk Utility, and then TechTool Deluxe, but nothing appears in either of them. So I cannot access the hard drive in order to try a software repair, or to change the startup drive.
I am hoping that the Seagate slave drive is working -- that has almost all of my data anyway -- and that I can get it to boot if it is in the master position. If you savvy and experienced people say that I can swap them, then I'll give it a shot.
If you have any better suggestions, I am willing to follow those too. I am running out of things to try!
Thanks in advance, and peace,
Charles

Hi BDAqua,
And thanks for your prompt help. I like the idea of using the cable to connect my two old hard drives directly to my laptop. I am unfamiliar with the cable, however, and I have three questions:
1. Will it come with instructions for use?
2. It looks like I simply remove the hard drive and connect it to the USB port on my laptop. Why then do I need to set the drive to master? (I installed my second hard drive about 8 years ago, and I no longer remember the significance of master/slave.)
3. If I am very careful -- and I am -- are you fairly certain that I'll not fry my hard drive?
If you cannot help me with these questions, or are too busy, please know that I am grateful for your help.
Peace,
Charles

I want to Connect my Mac Mini as a Slave to a Mac pro Server while at the same time using the Mac mini's thunderbolt ports peripherals ( ie monitor, Sound Card, Hard drives) Creating a poor man's new mac Pro. Can this be Done?

I want to Connect my Mac Mini as a Slave to a Mac pro Server while at the same time using the Mac mini's thunderbolt ports peripherals ( ie monitor, Sound Card, Hard drives) Creating a poor man's new mac Pro. Can this be Done?

Well, I really would love the new unreleased mac pro however , I'm not sure of the expected cost , Everyone speculates from $3,000 to $8,000, in which I may have to wait a while to purchase.
To the point .... I want fully functional thunderbolt ports to be on the current mac pro's .... wonder if anyone had workarounds yet?... or could I chain the the current mac pro to a mac mini to make that happen?

[SOLVED]New Build, no sound, Alsa unable to open slave

I've been happily using Arch on an old laptop I had lying around for 4/5 months, alongside ARM on my Raspberry Pi for a year or so. Being more than happy with it I decided to sell my 2011 i5 iMac, build a pc and hopefully learn something along the way. I mention this as it's my first build and the issue may be hardware realted, or more likely my assembly of the hardware, I've updated my sig to reflect the new parts.
The first decision I made two days ago upon putting the system together. I had two plugs, one for HD audio, another for Realtek audio, I went with the HD option. The other variable that is new to me is an audio option in the Gigabyte uefi/bios for audio which has options for enabled, disabled & auto - I've tried all three. I thought at first going with HD option may have meant sound only via hdmi, I'm using an old vga monitor, but after a little reading it seems the HD option should work with the standard audio out's on the motherboard & case too.
I've got a 3.5mm jack plugged into the line out on the back of the motherboard going to a phono connection on my stereo, I've also tried the headphone out on the front of the case, Zalman Z9.
I've installed alsa-plugins and alsa-utils. Upon running speaker-test, or speaker-test -c 2 I'm getting:
speaker-test -c 2
speaker-test 1.0.27.2

I've tried a few variations in .asoundrc based on the wiki example with no luck.
I'm lost, this is the first time I've had sound issues with linux and I'm really not sure if it's rooted in the hardware, my first attempt at building a pc or a simple alsa config issue.
Googling for unable to open slave in alsa seems to bring up mainly conflicting programm issues whic I don't think is my issue as I have no sound at all.
*edit*
perhaps this should be in newbie corner? my linux sound knowledge is definitely newbie status.

Solved, not sure where I was going wrong in my initial attempts but a simple .asoundrc has my speakers singing. Could have sworn this was tried to death in the first half hour or so, oh well.
On the plus side I spent my lunch hour today getting a rough idea of sound on linux and alsa preparing for a fight with my new build, ten minutes after booting up the new machine on my return home & all is well.

Error when running ethernet modbus slave demon in an executable - reoccurence

Thought I'd solved this with the help of the mass compile function. However, it seems to have come back. Maybe it never went away.
Brief summary - I'm trying to create an exe of the MB Ethernet Slave example.vi in LV 2013. I can create the exe OK but when I run it I get an error 1003 at invoke node. "This VI is broken or contains a sub VI that LabView can't locate. Verify that you can run the VI. VI path C:\Modbus\Source code\Slave demon.vi."
Well I can run the slave demon VI with no problems. I can also run the MB Ethernet Slave example VI with no problem.
In the MB Ethernet slave example VI there is an invoke node that calls the slave demon vi. I've used the slave demon VI path constant as an input to the invoke node so that the exe shouldn't have a problem locating it.
I've also checked out the sub VIs of the slave demon and they all seem to be present in my project. I've also tried a few different build settings - all to no avail. All VIs have been mass compiled under LV 2013.
Maybe the exe is struggling to locate the TCP functions.
Any help would be much appreciated.
Attachments:
MB Ethernet Example Slave.vi ‏47 KB

I have checked the path and double checked by dragging the VI into an empty path constant. I also created a version that uses the file dialog express VI so that I can select the slave demon VI when the program runs. I've also set the slave demon to be always included in the project build. The error message still appears.
By disabling sections of the slave demon vi I found that a VI called Internecine Avoider was linked to the appearance of the invoke node error message. By disabling this VI I could get the invoke node error message to disappear, although the slave demon then didn't work as intended. This VI is included in my project under the vi.lib so it should be found.

Modbus Slave Demon - Executable cannot find VI.

I have included in my application Modbus Ethernet Example Slave, which I've altered a bit ( only the inside of While Loop ). Everything is working fine until I've come to using an executable built from my project.
When I start it I got: Error 7 occurred at Open VI Reference in Modbus Init.vi->Main_v0.3.5.vi
Possible reason: LabVIEW: File not found. The file might have been moved or deleted, or the file path might be incorrectly formatted for the operating system.
In my project library I have Modbus Ethernet Example Slave in directory where the .lvproj file is, and the so the "Open VI Refference.vi" gets it from there (path is built using "Application Directrory Constant" + Name of VI).
I've also set "Always include" for MB Eth Example Slave in build properties but I still get the error of not founding the VI.
Do You have any idea why is it happening?

For your example, your exe has to reside in the same folder as the project as well.
Kudos and Accepted as Solution are welcome!

How do I set up a PCI-DNET card as master with A-B DNI as slave?

I'm trying to communicate with an Allen Bradley PLC through DeviceNet. I have a NI PCI-DNet card in my computer, and an Allen-Bradley 1761-NET-DNI interface between my PLC and the DeviceNet network. Does anyone know how to set up my National Instruments card as the Master of my PLC/DNI combination? Thanks in advance for the help.
Mark

Hi Mark:
The PCI-DNET card should set itself up as the master by default. As a matter of fact it should take more work to get it be the slave than to get it to be the master. Is this not what you are experiencing? Is there some sort of Allen-Bradley software that you have installed that is not allowing the NI board to be the master?
The DNET Manual states on page 4-8 that NI-DNET assumes that it is the only master in your DeviceNet system.

How can I run more than one VST on a PC slave running Logic 5.5?

I have moved from PC to Intel Mac (good!) and wish to run several non Intel VST apps from a slave PC running Logic 5.5 (ie Trilogy, Atmosphere).
My question is (and forgive my stupidity if the answer is obvious) how can I address each virtual instrument from the Mac? Currently I operate MidioverLAN CP which enables my PC computer to receive midi but I seem only to be able to access one instrument at a time, not permitting me to run several apps at once.
many thanks in advance for any kind help

Logic 5.5 is not an ideal VST host, as by default, only one virtual instrument is in Live mode, and you can't rig up environment solutions without a large latency (which makes it unusable).
There is a workaround involving putting a bypassed IO plugin on your instrument tracks, and then you can use environment cabling without the large latency (it tricks Logic into putting all instruments in Live mode). Then you'd cable your physical input through a channel splitter and onto the audio instruments to assign each a MIDI channel as has been discussed to death on this forum.
If there isn't a reason you must use Logic 5.5 PC to do this, then there are much better PC VST hosting apps and I recommend looking into them...

How to slave a Macbook pro with no OS

Helping a friend who just got a (Macbook pro 2) secondhand without any OS installed (HD wiped clean).
He is replacing his current MB Pro that is running 10.4.11.
I hoped a USB to USB would allow the new computer to be recognized as a HD on the desktop of the old one, but that's not working.
How do I get the old one (MB Pro) to recognize the new OS-less one (Macbook pro 2) so that I can clone the old computer to the new. He cannot find any disks in his house after version 9 (!!), so I cannot install another copy of the OS on the new computer and slave it directly.
Any ideas how to accomplish this? Seems like it ought to be easy, but I'm doing this long distance without the computers in front of me, and I'm at a loss.
Thanks for your help.

Connect them with a Firewire cable then Boot the old MacBook Pro with 'T' held down to force Target disc mode (will appear as a Volume on the other Desktop) then you should be able to clone over.

Using a second computer as a external midi instrument or DAW slave?

So this is my current setup:
iMac 24(FW 800 & 400) with logic 8 & reason 4,
Focusrite Saffire Pro 40 firewire (x2) sound card/pre-amp,
Blackbook with MainStage & Reason 4.
& this is what I would like to do:
Use my imac as my main DAW master, (currently tracking to an external FW800 drive & pulling loops from a USB drive), & use my blackbook to run reason as a external midi device or slave.
My Saffire Pro 40 has 2xFW400 ports so I can connect both machines to it.
The idea behind this setup is to pull as many software sounds from the Blackbook & mainly use the imac to run Logic.
Does this make sense? & if so, what's the best way to execute this?
thanks in advance

Hello -
I'm not entirely sure that one audio device such as the Saffire Pro 40 with 2 Firewire ports can be shared between two computers. It was always my impression that the second Firewire port was available to "daisy chain" another audio device or hard drive. Before you proceed, you might want to check with the company that manufactures the Saffire Pro 40 and make sure that two computers can interphase with it.
With regards to using a second computer as a "slave machine", it seems that many, many people do have such configurations to help spread the CPU and memory work-load. My happy Mac Pro is set up to work with a potential of two other "slave machines". When I use this set up, it works wonderfully. But, for most of the time, my happy Mac Pro can manage most sequencing projects (mostly orchestral with LOTS of instruments) on its own. Each computer, however, has its own audio device. All are connected to the Mac Pro using the ADAT light inputs/outputs from each audio device (I use MOTU's audio devices) and are managed midi-wise using Music Lab's MOLCP 3.
Good luck. . .

Why can't i read lin slave response in xnet

Hello,
we have developed a small lin application that starts xnet schedulle and sends master frames and headers.
I am trying to read all the frames on the bus and unfortunately i only see the master frames. The slave headers from master are not filled by the slave.
We are using single point frame approach.
Also, i have observed that when i disconnect the slave from the network, the slave headers are send very fast(as it should be). But when i
connect the slave, the headers are sent more rare and the payload is not completed by the slave.
The slave is working ok! because we send frames manually without the schedulle and the slave always responded good.
Which seems to be the problem?

It's hard to say, can you post your source? I've had success with LIN and XNet with signals, but haven't had a need to try frames yet. My setup is similar to what you described. I create two sessions for Signals Out Single-Point, and Signals In XY. Then I have a write LIN Schedule on the Signal Out session selecting a schedule from the database. Then I write Signal Single-Point on the Signal Output. Then periodically I read Signal XY using the Signal Input session. After doing this my read then returns all my signals once every 200ms or so, which is based on the schedule selected. I've never done frame on LIN but I assume it is similar.

How to navigate from view of slave DC to view of matser DC?

Hello!
I've got DC1 (master) and DC2 (slave) in different projects. Both projects are WD Java local DC projects. DC2 has one component (say A) with view, window, view interface, controller and controller interface and has no applications. This view should be called at start of application. Only DC1 has application. Public parts created properly so DC2 visible for DC1.
In main window of DC1 I embedded View Interface from DC2 and make it default. View Interface has outbound plug connected with inbound plug for View of DC1.
What I should to do to allow user navigate from View Interface of DC2 to view of DC1 by press button placed at view of DC2?
I'm working with NW7.0.
Regards, Lev.

Hi
One solution will be already provided by jithin james .
Apart from that if u want to make something generic (For your case View interface of different Dc) follow this [Best practices |https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/a0409d83-5ed5-2910-ef91-e41da6d5b8b4]
