It is alwayes me with a beginner problem!

Now the situation is this:
I mounted the mquque (OK).
Then, as I try to \"start the runtime system on the development machine\" (bash$ rt_ini &),
after having typed:

rt_xtt

what happens is nothing.
I mean that the console remains there but no new window appairs.

Since I supposed I made some error before, I tried also to do the same with the pwrdemo44
project but the result is the same.

Any idea?

Thanks in advance

Hi,

To start to runtime environment you have to define PWR_BUS_ID to the busid in the BusConfig object in the DirectoryVolume. If you use the same as in the demo project which i think it's 999 it would be

$ export PWR_BUS_ID=999

If you have made any start attemps previously, or have started the demoproject, you have to stop/remove this with

$ source pwr_stop.sh

then start the runtime with

$ rt_ini &

You now should se a lot of processes (rt_ini, rt_qmon, rt_net etc) with 'ps x'

If not, reset with pwr_stop.sh again and start rt_ini with the switch -i to get any error message

$ rt_ini -i

Messages containing -E- or -F- are error messages.

Hi,

after having applied your suggestions, I realized that I had not to use uppercase chars because not alwayes they are maintained in file names.
Now i removed the uppercase chars from my PC name and the boot file is found as well as the voume file.
But an other error happens: it is looked for
/usr/local/bin/java
while on my PC there is a
/usr/local/java

How can I say Proview to configure properly?

Hi,

I have sent an help equest some hour ago but there is some new: the problem is caused by the variable jdk_home that is set to /usr/local//bin.
Now I have manually corrected it to /usr/bin but after having launched

rt:ini -i

a lot of processesare started (I think OK) but all them give the same error:

sched_scheduler: Operation not permitted failed to set pid NNNNN's policy

Is it a mistake?

Thanks in advance

Hi,

This is no mistake. We use a program rt_prio to set the real time scheduling mechanism. You need to be root to switch to a real-time scheduler. If you change owner of the rt_prio-program located in $pwr_exe to root and also set the s-bit you will get rid of these messages and the programs will run with real-time scheduling mechanism.

If you also want the plc-program to run with real-time scheduling you should do the same thing to this (observe you have to do for every new plc-program you build). Set root as the owner and also the s-bit.

Thank you very much!
