Hi all ,

we have configured a Primary and Standby database environment. We have a cascaded and a cascading Standby database in this environment. The Oracle release of all 3 databases is 12.2.0.1.0. The ugrade onto this release is several months ago. Since this week we are receiving the error "ORA-07445: exception encountered: core dump [ktaftt()+85] [SIGSEGV] [ADDR:0x7FFEC94075F8] [PC:0x166F995] [Address not mapped to object] []" in the cascaded Standby database. The functionality of the database seems not to be disturbed - redo log transport etc. works as expected. The command "validate check logical database include current controlfile plus archivelog" didn't return any failure

Howdy, Stranger!
