Hello,
I am new to polygraph, and unfortunately, the lab I have at my disposal
is entirely Solaris, so I can't run Polygraph on Freebsd. I am
currently running successfully with version 2.2.9, however, I ran into a
problem with the 2.5.4 version that I wanted to share (and fix if
possible).
First, let me say I am running solaris 7, and compiled without errors
using GNU C++. The problem is a clock sync error -
When I run the simple.pg workload for both the server and client on the
same system, I get clock out of sync errors. They appear to be off by 1
hour, but since the client and server are on the same system, obviously
the clocks aren't off. I am wondering if different time functions are
used, and maybe one is implemented differently under solaris than other
unix varieties...
Here are some details from my tests:
aqua$ sudo src/server/polysrv --config workloads/simple.pg --verb_lvl
5
aqua$ sudo src/client/polyclt --config workloads/simple.pg --verb_lvl
5
Here are some of the messages from the Client Console. The messages are
frequent in the begining, and then the time between them seems to
double:
