Two instances running at the same time on one machine - error ORA-28547

Hi,

Two processes running at the same time in Lookout

I have installed Lookout 5.0 with 200 I/O Points onto our server computer. The application of motion control is next to the 200 I/O points through OPC PMAC server/client. Now I would like to have a second process in the same server for trouble shooting and testing without stopping the motion control process. However, this second testing process could have also many I/O points through Serial and USB ports. I assume that the total amount of I/O points of both processes will be greater than 200.I prefer to have independent processes for control and testing because access levels. Can I have these two processes running at the same time when needed?

Hi,
From your description you are using a third party OPC server for the motion application. You could have a second Lookout process communicating with the same OPC server with no problems, as long as you do not exceed the number of I/O points your license supports.
Also, the process you are using for testing obviously could not overwrite datamembers (or registers if you will) that would interfere in the overall application, in other words you can test your application as long as you keep the coherency of the test.
So the answer would be, yes it is possible, however you are still limited to the number of I/O's your license supports... You may even consider upgrade the number of I/O's you have in your license.

How Can I create a cluster of two instances running on the same server?

Hello,
I can't find how to create a cluster or even a failover rule for my two instances running on the same server ODSEE 11gR1.
Could you please help?

Hello,
Clustering (intended as Sun Cluster, Veritas Cluster, etc... ) IS NOT SUPPORTED since 7.0:
http://docs.oracle.com/cd/E20295_01/pdf/821-1216.pdf [page 20]
and, based on my own experience, is the WORST way of achieving high availability of an LDAP Directory Service and an almost GRANTED way to get replication issues in your topology (lock, split, re-init, etc...).

Running two stepper motors at the same time from one port

Hello,
I have to run two motors at the same time - one used to move a linear ball screw and one to turn a grip. I am doing tension and torsion testing on small wires, but tension and torsion have to be done at the same time. I also have to build in the ability for each motor to take multiple steps, ie. have a motor take x number steps at y velocity and then move x number of steps at z velocity. Both motors need to be able to do this. However, I am having problems getting the motors to run at the same time and to take all the steps. The motors are connected to two RMS Technologies R356 controllers. Both of the controllers are then connected to one RS485 to USB converter card, and that card is connected to one of the USB ports in the computer. Currently, I pass an array of commands to two for loops each containing VISA read and writes. I've attached the vi to look at. All of the timing stuff in the code is because a new command cannot be sent to the controller before the motor is done executing the previous command. If commands are sent right after one another, the controller will only execute the first command and then return with an error.
Does anyone have a suggestion as to what I am doing wrong?
Thanks in advance for any help.

I'm not too clear on exactly what you are trying to accomplish or some of the details.
Are there equal number of torsion and tension steps?
Is there a pairing between a torsion and tension? For example, you want to tension and torsion simultaneously, but those two together make a complete step?
Do you want to wait until both the torsion and tension have completed before moving on to the next torsion/tension pair?
Is there any time delay you want to hold at before moving on to the next step.
When working with state machines, it is important not only to define the states, but also the logical stepping from one state to the next, or alternatives based on conditions. It could be flowchard, but sometimes people call them state charts.
Right now your latest posting has goes to "Write to Motor" event though and will wait there forever because there is nothing in the queue to write out through the VISA port.
Let's assume your first state would happen to be Enqueue Tension (in order to get something in the queue), you will actually queue up all your tension commands at once with the For loop. Then i will be 1 less than the size of the array it always will be because for an array size n, i will go from 0 to n-1 on each iteration. So your false case will run and you will go to "Write to Motor". Write to Motor will run and dequeue the first command then go to Waiting for Response. Waiting for response will iterate through the while loop until 66 or 67 comes back. I assume only 66 will come back for tension since you have yet to write a torsion command. Once that comes back, it will go to Enqueue Tension again and insert a whole other series of commands. Then go back to write Motor and will take out the 2nd queue element from the first set of commands your wrote. It will stay in a Tension mode and the Queue will grow endlessly putting in a whole new series for each element that you dequeue.
A state machine is the way to go, but I can't really sketch one out for you because I'm not sure exactly how your applications is supposed to work. If a tension and torsion command are paired together, perhaps you should just queue them together and write them out at once. But the key thing is to sketch out on paper your application and flowchart exactly how the program should progress from step to step.
PS: One other thing, make sure you wire the queue reference wire through all states.

FRM: 10270 Cannot attach the library when two forms run at the same time

I get the error message FRM: 10270 Cannot attach the library SYSLIB while opening menu BMENU but only when i try to open a second form while the first form is still running.
Both forms are working fine as long as they ar not running at the same time.
It seems like the second form opening does not have access to the FORMS60_PATH, because you can not open a third form because it can't find it.
All the forms anf libraries (plx)is in the FORMS60_PATH.
I am running developer_6i forms & reports on a HPUX 11i machine and I am trying to access them through jinitiator 1.3.1.9 on a XP machine.

Thanks a lot for the tip. I used truss and realised that it found the library but was not allowed to open it. The kernel parameter maxfiles was set to low.
I increased it and everything works ok

Multiple Libraries for Video running at the same time on one PC

Hi Everyone -
I want to clarify this is for VIDEO files, not music for my 6 ATV's on the network.
Problem: I have well over 1000 VIDEOS in my iTunes Library, and I am wanting to have multiple libraries availible at the same time; not just whichever the computer has open.
We have several atv's on the network and I would like to take my video organization one step further; instead of scrolling forever in the atv menus for the video you want; I could make several libraries all availible at the same time.
Such as:
Kids Library
Workout Library
Parents Library
etc
This in turn would shrink the primary library and have less videos to sort by. I know how to create the Libraries, I just dont know how to have them all running at the same time.
Infastructure:
Windows 7 Ultimate with Drobo B800FS (16TB of storage) all connected to Cisco 3660 Gig switch with multiple atv's hardwired back.

iTunes can only open one library at a time. If you have multiple computers, or virtual machines, each could be serving a different library.

The message "restore previous settings" (or somethinglike that) comes up when mozilla is launched. Are there two programs running at the same time.

Frequently there are two mozilla programs launched when the icon is hit. Often the "restore previous settings" message is displayed. I also often loose my connection to the internet which I suspect is somehow connected to the dual mozilla problem. How can I eliminate this situation? Can I uninstall mozilla and then download it again via explorer?

Having two background brarchive running at the same time with -f 1 options

Good morning,
I need to run two brarchive in parallel as background process.
I would like to have on for the save and one for the copy.
I need that because they would have different files.
1. Is this configuration supported or not?
As a file is created for the locking (.lock.bra) I have the feeling that a single process is supported?
2. Just to double check, can I run two brarchive with two different config file in a serial manner
(lauch the 1st one, wait for its end, launch the 2nd one, waits for its end).
3. If you are using that kind script on your systems, could you please provide them?
4. If brarchive is launched by a script how do you shut it?
Do you do just a kill of the script or do you kill it and send another signal to the brarchive if it is currently running?
Thanks in advance for your answers.

Good afternoon Eric,
> Why do you want to use option -f 1? what are the reasons being this?
-f makes it run in background.
For me, there two advantages for doing that.
1. You start it once, when you start sap, and it runs regularly
2. When you stop sap, you stop braarchive. Then you are sure that no crontab jobs are going to be started when you have stopped SAP.
> you want to stop brarchive with option -f running? try:
>
> brarchive -f stop
This is what is currently done right now.
It works well.
I can use it because we do a single copy of the archive log up to now.
We are going to run two brarchives (one to save to a tape robot with backint and one that scp).
I would like this to run as daemon.
Now, that you have answered that I can not have two brarchives running at the same time (thanks for your answer),
I need to write my own daemon in sh or perl that would do:
1. Run brarchive first run (with -p backint init<SID>.sap file)
2. Wait for the en of the brarchive process and log
3. Run brarchive second run (with -p scp/stage init<SID>.sap file)
4. Wait for the end of the brarchive process and log
5. Sleep during a few minutes
6. Handle stop signal so that it ends the forked brarchive that may be running.
I am sure that people on this forum have already wrote such scripts.
I may open another thread as it divert a little from my original question.
Thanks in advance for your help.

How to insert into two differents tables at the same time

Hi
I'm newer using JDev, (version 3.1.1.2 cause the OAS seems to support just the JSP 1.0)
and I want to insert into two differents tables at the same time using one view.
How can I do that ?
TIA
Edgar

Oracle 8i supports 'INSTEAD OF' triggers on object views so you could use a process similar to the following:
1. Create an object view that joins your two tables. 'CREATE OR REPLACE VIEW test AS SELECT d.deptno, d.deptname, e.empname FROM DEPT d, EMP E'.
2. Create an INSTEAD OF trigger on the view.
3. Put code in the trigger that looks at the :NEW values being processed and determines which columns should be used to INSERT or UPDATE for each table. Crude pseudo-code might be:
IF :NEW.deptno NOT IN (SELECT deptno FROM DEPT) THEN
INSERT INTO dept VALUES(:NEW.deptno, :NEW.deptname);
INSERT INTO emp VALUES (:NEW.deptno, :NEW.empname);
ELSE
IF :NEW.deptname IS NOT NULL THEN
UPDATE dept SET deptname = :NEW.deptname
WHERE deptno = :NEW.deptno;
END IF;
IF :NEW.empname IS NOT NULL THEN
UPDATE emp SET empname = :NEW.empname
WHERE deptno = :NEW.deptno;
Try something along those lines.

How to run two vi's at the same time, one uses an AI task with 8 AI channels the other a single AI and AO channel???

Hello Everyone,
Here is my situation. I have one vi that is reading an AI task of 8 channels AI0 --> AI7 (one sample on demand) and also has control of all of the digital outputs on the board. My problem is that I want to run another vi that will use the last AI channel AI8 and an AO channel AO0. These two vi's do not need to know anything about one another but I do need them both to be running at the same time. Currently when I try running the two vi's together both vi's crash and I get an error message stating that the AI8 pin is reserved. AI8 is not part of the task and is not refrenced anywere in the larger vi. I am assuming that this problem is do to the fact that the larger vi is occupying the DAQ board, cycling through the task when the smaller vi is requesting data from AI8 and the DAQ board cannot do two things at once. The sampling rate on the smaller vi is not really that important. Is there anyway I can get the smaller vi to read from AI8 and not crash??? Software and Hardware listed below. Thanks in advance for any suggestions.

Two Telnet read VI's running at the same time interfere with each other

I have a situation where multiple tests must test multiple UUT’s on the same computer. To send commands to and get responses from the UUT's I use a telnet session. The telnet read VI uses a semaphore. Therefore when two separate top level VI's are running, each calling the Telnet read VI, if one Top Level VI is using the Telnet Read VI the other Top Level VI waits for the first one to complete before it can use the Telnet Read VI. This VI is setup for reentrant execution but because of the semaphore it cannot truly be used as a reentrant function. This causes severe problems when trying to communicate with two different telnet sessions simultaneously.
In the past I have avoided this problem by compiling everything into an executable. Then each Top Level program runs completely independently with no interdependences. However, now I am implementing Teststand and I need to call the same Top Level VI's. I need to be able to get information into them and back out of them from Teststand. This means that I can no longer compile them into stand alone executables. I did compile each top level VI into its own Share DLL thinking that then each top level program would have its own library to call upon. This did not work. Even though both top level programs are compiled into their own DLL there is still interdependency when calling the telnet read VI. One program waits for the other to finish reading from its telnet connection before it can read from its own telnet connection. Since I have to continuously read from the telnet connection, sometimes for up to half and hour, the tests do not function simultaneously. How can I get around this? Is there a solution?
Josh
PS The Telnet Read VI I am refering to came with the Internet Toolset package. Attached is a copy of the VI I use to communicat with the UUT's.
Attachments:
GUI_Telnet_W-R_Auto.vi ‏64 KB

Sorry about the confusion.
The file I attached is in the hierarchy of two separate top-level VI's. The telnet connect is opened once and closed once in each top-level program. The ref number is then passed into and out of the VI that I attached. I use this VI to repeatedly send commands via telnet and wait for the appropriate responses. The telnet read VI is given a read line separator and reads from the telnet connection until it matches the read line separator with a text string read back from the telnet connection. If not match is found it times out and creates an error.
I am not sure how to provide an example of the overall scheme since the problem occurs when both top level VI's are compiled each into their own shared DLLs. Those DLLs are then call from Teststand and at some points they are both running at the same time on the same computer connected to two different UUT's.
The question I have is why does one DLL share functions with the other? When one DLL is using the telnet read VI the other DLL waits for the first one to finish with it before it can it use the telnet read VI. If they were both compiled separately each into their own DLL shouldn't they each have their own set of functions to call upon instead of having to share? I know that if the two top-level VI's are not compiled they cannot both execute the same sub-VI at the same time. The only way to get around this is to set the execution property on the sub-VI to reentrant.
I actually fixed the problem by setting the VI I attached and the Telnet Buffered Read.VI (called by Telnet Read.vi) execution properties to reentrant. However, I am still concerned about two separate DLLs sharing sub-VIs. Why does it do this?

Collecting data from advantech-usb4704 with two different apps at the same time

I wonder if I can access to Advantech-4704 with two different applications at the same time?
I use this block in my vis.
I have enough ports, but inputs are needed in completely different applications. Do I have to close one of them or can they run simultaneously?
Thankyou!

Dear gtu,
as nathand said, usually it is not supported to access the same physical resource simultaneously from multiple programs. In case of DAQmx for instance, you will get an error message which says that the resource is already reserved. I suppose the same would happen with your driver, however it might be worth a try.
One workaround could be however if you revise your applications and merge the codes if it is possible so that no concurent resource allocation takes place.

Multiple scripts running at the same time?

Is there a way to have multiple scripts successfully running at the same time?
At the moment if I start a second script while the first one is still running, the second one completes successfully but the first one stops. This seems to be because the first one is no longer the active document once the second one opens so can't continue.
Is there another way to script things like this so that multiple can run independently at the same time? You might ask why I'd want to run two at the same time and not just wait, but i've setup an asp.net web form front end and having problems if two people click the button around the same time.
I'm guessing this isn't going to be possible and i'm going to have to look for ways of doing this in asp.net instead and somehow queue the requests so you have to wait longer if the script is already running?
Thanks,
Andy

This is correct. The scripting interface to PS is single-threaded so you will need to queue up requests.

Play two video files at the same time.

I am trying to play two video files at the same time. I create two threads, each of which has its own frame, playing button, and builds its own graph to play the file. Now everything seems works except that when the first file is being played and I hit PLAY
to play the second file, the program plays the second file but the first one is paused; furthermore the control button has no response for the first one. Did I miss anything? Can anyone help me figure out the problem?
Best,
Fayin

You don't need separate threads for 2+ playback pipelines because the filters create worker threads internally and don't block execution on calling thread.
If you decide to keep separate threads, you will have to follow Michel's advice and have message pumps on those threads.
You can also have both files in the same graph, in which case you have perfect sync between them (both start playing together in sync), however you cannot pause/stop/run files separately.
The problem you described is most likely not a DirectShow problem and is rather about generic threading, COM or window messaging.
