Problem
You have a problem with a process, running some job on Solaris and need to see some debug information.
Sometimes the problem is a missing library, etc and you need to spot the missing dependency.
Symptoms could be a binary runs fine on one system and fails on another.
Solution
Run truss with the binary, to spot all the files it opens and for additional information. Sometimes you can even spot where the log files are. 🙂
Example
This will show system process debug (solaris) for all exec/reads for a running process.
truss -xall -vall -rall -t'read' -p PID
This will run truss with the process.
truss -xall -vall -rall -t'read' program
