Information in this document applies to any platform.
The issue documented here is limited in scope to 11g and newer instances.
The following errors are intermittently posted to the alert.log of an 11g database.
ORA-609 Opiodr Aborting Process Unknown Ospid <nnnn>
ORA-609 Opiodr Aborting Process Unknown Ospid
The ORA-609 might be accompanied by either the TNS-12537 or the TNS-12547 and might also include the following timeout messages:
Fatal NI connect error 12170.
TNS-12535: TNS:operation timed out
ns secondary err code: 12560
nt main err code: 505
This is likely a new installation of the 11g database. The ORA-609 error code was introduced in 11g. Also introduced in 11g is the ADR diagnostic method which results in TNS errors such as this to be thrown in the alert versus the sqlnet.log.
