I have a red hat server running an oracle database. I can see in oracles rdbms' alert logs that a network outage of some sort occurred.
ORA-16198: Timeout incurred on internal channel during remote archival LGWR: Network asynch I/O wait error 16198 log 3 service
I want to know if the server registered something similar. I'm looking for NIC failures or simply a disconnection from the switch.
Note that the outage was temporary. I can access the server through ssh and I can ping the database service and the server itself, so my only way to tell that something happened is from logs.
Where can I look for that?
