What does ChgCnt: value in SHOW CPU /FULL mean?

[Sebastian Bazley]

Not using Galaxy on the ES40 (obviously).

I've seen non-zero ChgCnt fields in output from GS160s that are not running Galaxy.

Hi,

I've tried it and it really changes when you stop or start CPU. So I assume it is an counter for CPU state changes.

Galaxy doesn't needed. MultiCPUs-systems with EV68 and EV7 work right. It's the fact. Decription of ChngCnt is very difficult to find ... next fact :-)

Maybe I need to file a documentation bug ...

Sebastian,

the Change Counter (ChgCnt) is part of the CFG_NODE structure (field cfg$w_change_counter, see SYS$LIBRARY:LIB.REQ). It is used to synchronize state changes for machines, which support a configuration tree (see SDA> SHOW GCT).

After a successful configuration tree node state change (routine cfg$set_node_flags), this counter is incremented.

Volker.
