ScenarioLoder Error "Permission denied"

[José Carlos de Campos]

Hi,

I compiled DX10 and installed it on my computer. After I changed config.xml of ExampleDA to enable system ADAPT and ran ./ScenarioLoder , the application returns:

SL: INFO: Iterating through DAs in:
/home/zecarlos/Desktop/DXC10v2.1-Linux-x86-Oracle_0/DXC/Algs
SL: INFO: Loading Diagnoser: Example Diagnosis Algorithm
SL: ERROR: Permission denied
SL: ERROR: Exception. Terminating DA.
DA unable to connect. Make sure ScenarioLoader (or StandaloneSDS) is running.
SL: INFO: Exiting...
SL: ERROR: Timed out waiting for scenario start (check DA -> SDS connection).
SL: ERROR: Exception. Terminating DA.
SL: INFO: Exiting...

I analyzed the ScenarioLoder.cpp and the "SL: ERROR: Permission denied" happend at line 192 "da->start();" .

It doesn't permission to run or write something, but what?!

---8<---

When I run ./SDS -a -v ADAPT -o ../Scenarios/Results/a.out ../Scenarios/ADAPT/Exp_1158_pb_ADAPT.scn the aplication returns:

Writing to file.

Awaiting DA...

SDS: INFO: Parsing scenario file: ../Scenarios/ADAPT/Exp_1158_pb_ADAPT.scn

SDS: INFO: Running in abbreviated mode.

Scenario ended.

The first four lines of a.out (output file):

Can you tell me if this result is correct? Only just to know that I am running the example correctly.

FYI: my sistem is Debian GNU/Linux Wheezy

Hi José,

It seems to me that the problem is that you're trying to run a 32-bit executable on a 64-bit machine or vice-versa or a missing/wrong .so or something like that. To solve this fully could you also send the output of:

ldd /home/zecarlos/Desktop/DXC10v2.1-Linux-x86-Oracle_0/DXC/Algs/ExampleDA/ExampleDA

also

ldd /home/zecarlos/Desktop/DXC10v2.1-Linux-x86-Oracle_0/DXC/Lib/libdxcApi.so

Sorry it took so many steps - I am still unsure in the RCoF.

I don't think so.... I tried it in a virtual machine with Ubuntu 32bits ( uname -a : Linux vb-VirtualBox 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:50 UTC 2011 i686 i686 i386 GNU/Linux ) and the ./ScenarioLoader returns the same output.

I think the problem might be with the Oracle, since running SDS in standalone mode seems to work. Just to make sure it isn't a permissions issue, could you check that the following files are readable:

bin/models/*
SystemCatalogs/*

And that the Oracle binary in bin/ has the +x bit set?

Yes, the files on this foldes are readable. All files have -rw-r--r-- .

 

And that the Oracle binary in bin/ has the +x bit set?

Oracle binary had -rw-r--r-- so I changed to -rwxr-xr-x .

Now, when I run ./ScenarioLoader the output is:

What hostname?

[David Garcia]

It's trying to resolve the hostname "localhost". Do you have it in your /etc/hosts?

And if you type just `hostname'?

I get "vaio" (without quotes).

Please consider the environment before printing this e-mail

[David Garcia]

Can you "ping localhost"? I suspect you will be able to, since the other DXC programs seem to be communicating fine, but it's worth a shot.

If ping works, I think we'll have to send you an updated version of the Oracle. (There is a patched version available on the website, but I think the issue it patches is different--though you should give it a try anyhow).

NASA folks will have to help us out with this, as the Oracle depends on the HyDE API, which I don't currently have a copy of.

[Alexander Feldman]

José,

Which track are you in? If you're not developing for the industrial track you can disable the Oracle and the rest should work just fine.

No, I am not developing for the industrial track but for the software track. How can I disable the Oracle?

Yes, I can ping localhost and vaio.

I can try, where is the new version or patch?

Make sure there there is the line

RUN_ORACLE = "FALSE"

in Dxc.cfg

Yah, now it runs ok.

In the past other participants doesn't had the same problems with Oracle? Or everyone use the version for windows?!
