Oracle X$TRACE, Wait Event Internals and Background Process Communication
 
01:48:41
In this session we will look into some internals of Oracle background process communication and also some special types of wait events that most people aren’t aware of. We will use some exotic tracing for internals research and fun and some of this stuff is actually useful in real life too! I’m not going to reveal everything upfront, as this is a secret internals hacking session after all ;-) We will use various techniques to research what the “reliable message” wait event is about and how reliable background process communication is orchestrated in Oracle. This is a hacking session, not formal structured training, so I’ll just do free form demos and talk (probably no slides, just hacking stuff on the command line). Also, check out my full-week Advanced Oracle Troubleshooting online training at https://blog.tanelpoder.com/seminar
