DCN Ring Communication Errors / Database issue...
Later, we tried to download a small loop descriptor change to a loop in a different 460 subsystem. At this point the advabuild PAS entered a restart cycle (and continued to fail at the OMO step). The installed database, shown in Advabuild, had a strange ascii string as the project name, and a 12:00 AM install time.
A separate yet related issue is that Diagnostic Message list is reporting ring communication errors, yet DCNLOAD data loops show normal runtime values ~30% load.
I'm pretty sure we're hooped and need a full database compile & node reboots.
Well, I Think that once you restored the old database Backup you jeopardize the system, it seems that not all changes could have been successfully updated. I think that you already did it, but try to reboot all nodes one at a time, forcing every node to reload its portion of the database, I suggest try to do it first with the node where the issue started.
Compiling top-down the database (also compiling and linking all TCL codes and TLL) and re-booting nodes for sure will eliminate this head ache.
Feel free to contact me if needed.
