12.2 / Exadata : Session connect/disconnect & performance issue
Hello,
I have an Oracle job that is having performance issue.
The ADDM findings is : "session connection / disconnection"
In this job, there is only one active main session with the same SID, SERIAL #
Can a session disconnect and reconnect with the same SID / SERIAL #? Is it possible ?
How to diagnose this problem ?
See attached file.
Thanks.
GD.
