Miscellaneous changes in 10.5.1 affecting backwards compatibility
The following changes in Apama 10.5.1 affect backwards compatibility to previous Apama versions:
If the correlator or the IAF is configured to log to a file, then the log file being used is now output to
stderr. In the case of the correlator, this is the full path and filename, whereas the IAF only logs the filename.
The shutdown order of the connectivity chain components has changed. In previous versions, the codecs were shut down first, followed by the transport and host. As of this version, the host is shut down first (that is, calls into the host component of the chain are unblocked), followed by the codecs and the transport. See also
Lifetime of connectivity plug-ins.
When you develop your own connectivity plug-ins, you may have to update your plug-ins to reflect the changed behavior. Make sure that your testing includes shutting down the correlator (for example, using the PySys correlator.shutdown() method), since it is possible that this change in behavior makes shutdown issues in user-defined plug-ins more likely to show up.
