Signals (POSIX only)¶

Signals are a POSIX inter-process communications mechanism. If you are using Windows then this documentation does not apply.

Zope responds to signals which are sent to the process id specified in the file ‘$INSTANCE_HOME/var/Z2.pid’:

SIGHUP  - close open database connections, then restart the server
          process. A idiom for restarting a Zope server is:

          kill -HUP `cat $INSTANCE_HOME/var/z2.pid`

SIGTERM - close open database connections then shut down. A common
          idiom for shutting down Zope is:

          kill -TERM `cat $INSTANCE_HOME/var/Z2.pid`

SIGINT  - same as SIGTERM

SIGUSR2 - close and re-open all Zope log files (z2.log, event log,
          detailed log.) A common idiom after rotating Zope log files
          is:

          kill -USR2 `cat $INSTANCE_HOME/var/z2.pid`
