ccmd
If ccmd detects a hard error, it starts the hard_logger script to extract
additional information from the node through the JTAG interface. After
the hard_logger runs, ccmd resets the node or complex that failed.
This behavior can be stopped with autoreset.
ccmd sends output to the console. If running under X-windows as
sppuser, it sends its output to the teststation console message output
window. The -d debug option generates a substantial amount of console
output. Output is also sent to the file /spp/data/ccmd_log.
ccmd does respond to several signals. The SIGHUP signal tells ccmd to
rebuild the teststation database. A sigint or sigabort signal terminates
the ccmd process.
NOTE The time zone information is read when ccmd starts. If the time zone
information changes, ccmd should be restarted as well.
