Multiple Creo sessions problem

[mawyr]

Hello,

I have a problem with running multiple Creo sessions. I use Creo 2 and Creo 4 on Windows 10 and I have floating license in company. Problem occurs when I start second Creo session (2 or 4, does not matter). Second Creo opens but then every Creo start to work very very slow, it is impossible to do anything in program. When I close one session in Task Manager it goes back to normal work. Do you have any ideas how to fix it? 

Thank you in advance,

Maciej

Why are you running 2 sessions of Creo in the first place? One session can open multiple objects.

How much memory is on your machine?

What graphics card do you have?

Are you using Windchill for PDM?

Sometimes I need to work on two or more different projects with the same parts names inside. I have 16 GB memory and NVIDIA Quadro M1000M. I do not think it is hardware problem. I do not use Windchill at all.

Same part names in 2 sessions may be the problem.

Creo is designed, like it or not, to work with Windchill. There could be some file checking going on even when not using Windchill that could be causing the slowness. With Windchill if one user checks out a file, Windchill will notify ALL workspaces that contain that file that JoeJones has it checked out now. Some of that cross checking code could be working against you.

Hi,

maybe you can try creating second startup command in Creo.

1st startup command modification

Go to Parametric\bin directory.

Open parametric.psf in Notepad.

• modify DESC=Creo Parametric (default) line to DESC=Creo Parametric 1st
• add ENV=PTC_WF_ROOT=<some_absolute_path>\PTC_WF_ROOT_CR2_1st at the end of the file
  (I use ENV=PTC_WF_ROOT=E:\PTC\PTC_WF_ROOT_CR4_M090 in Creo 4.0)
• save

2nd startup command creation

Copy parametric.psf to parametric2.psf

Open parametric2.psf in Notepad.

• modify DESC=DESC=Creo Parametric 1st line to DESC=Creo Parametric 2nd
• add ENV=PTC_WF_ROOT=<some_absolute_path>\PTC_WF_ROOT_CR2_2nd at the end of the file
• save

Start Creo and select Creo Parametric 1st description from dialog box.

Start Creo and select Creo Parametric 2nd description from dialog box.

Test Creo response.
