I have model which I can successfully run using oplrun from command line. But if I launch the same model from the IDE, I get the error "OplRun is not responding, you must relaunch the RunConfig". This is even before the model starts running, so I am pretty sure it is not a memory issue. I faced this issue with 12.6 and so upgraded to 12.8 last week, but the issue persists.I also recenly ran Windows Update(the machine runs on Windows 7 Professional).

Any help to fix this will be appreciated. Here is the dump from the log file -

Hi,

can you attach your complete project so that other users could try ?

Alex,

This is not an issue with just one project, but with all the projects ( > 10 ) in my workspace. I uninstalled and re-installed OPL, but the error is still repeating. Could the recent Windows Update be the reason?

Thanks!

could  help

You could also try

oplide -clean

in the command line

I tried both the solutions you mentioned,but the problem still persists. It is not a memory issue, as I tried increasing operating system stack size. The log is still the same as I have posted in my original post. I believe this is the error -

ENTRY ilog.odms.ide.core 4 0 2018-06-25 11:18:53.570

!MESSAGE Connection refused to host: 127.0.0.1; nested exception is:

                java.net.ConnectException: Connection refused: connect

!STACK 0

But no idea how to fix this!

Hi,

have you tried to delete your workspace ?

Workspace

The workspace is the working directory in which you store your resources and work with them.

The workspace can be located anywhere on your file system, but its default location is:

C:\Users\IBM_ADMIN\workspace

Tried this just now - didn't help. But I noticed that when I created the new workspace, opened OPL and imported the project, the IDE was stuck at "Building Workspace(0%)" and finally had to kill it using task manager. What could cause the building process to hang?

Ok what about trying in collocated mode ?
