We just upgraded to PB 2019 R3 Build 2728 from PB 2017 R3 Build 1858.

Same problem here. Java program hangs after calling the pb application. No change were made on the java side either. PB upgraded to PB 2019. Worked fine in PB 2017. Broke in PB 2019.

Same OS version (Win 10), Same Java version, SameOS configuration.

Is adding "Start" on the calling application the only real solution for this issue?

I'm having the same problem executing my PB app from Java. Adding the "start" to the front like Marie did solves the problem when it's ok to run the exe in the background, but I have some exe's I need to wait until they're finished to get the results.

 

They hang in PB 2019 R3 but not PB 2019 R2. Nothing else changed. I am running on Windows 7, so I'll see if it's a problem under Windows 10, but I suspect it will be.

Hi Tom;

Just an FYI that PB2019R3 no longer supports W7.

HI,

We got it right with chaging Oracle forms and ADDED the start in the command line

lv_host_cmd := 'cmd.exe /c start S:\PB\' || lv_env || '\Test.exe ' || lv_exp_date || ' ' || lv_rand;

Client_Host(lv_host_cmd);

Regards

Hi Marie;

   In addition to Armeen's questions ...

    When the PB App hangs ... have you tried entering Task Manager and looking to see what TM says that the App is "waiting for"?

Regards ... Chris

This doesn't make any sense to me because they changes we have made I don't see how would possibly affect this.  Are you sure the only difference in PB versions?  It is same Windows OS version?  Same Oracle Forms version?  Same machine (i.e. Windows config exactly same)?
