ERROR at line 1:
ORA-3113: end-of-file on communication channel
ORA-3113: end-of-file on communication channel
Alert.log shows
ORA-7445: exception encountered: core dump [slmecpy()+132] [SIGSEGV] [Address not mapped to object] [0x400000000] [] []
Or an
ORA-00600: internal error code, arguments: [evapls1], [], [], [], [], [], [], []
The call stack for the ORA-7445 [slmecpy()+132] is as follows:
ksedmp <- ssexhd <- sigacthandler <- slmecpy
<- kzctxEUsrEnv <- evactx <- evaopn2 <- evaopn2
<- evareo <- expepr <- kzftChkAudit
<- kzctxEUsrEnv <- evactx <- evaopn2 <- evaopn2
<- evareo <- expepr <- kzftChkAudit
The call stack for the ORA-600 [evapls1] is as follows:
ksedst <- ksedmp <- ksfdmp <- kgerinv <- kgeasnmierr
<- evapls <- evaopn2 <- evareo <- expepr <- kzftChkAudit
<- evapls <- evaopn2 <- evareo <- expepr <- kzftChkAudit
The following queries can confirm if FGA is enabled on the base table's column(s):
SQL> select object_schema, object_name, policy_name
from DBA_FGA_AUDIT_TRAIL;
SQL> select OBJECT_SCHEMA, OBJECT_NAME, POLICY_NAME,
POLICY_COLUMN, POLICY_COLUMN_OPTIONS, ENABLED,
SEL, INS, UPD, DEL
from DBA_AUDIT_POLICIES;
from DBA_FGA_AUDIT_TRAIL;
SQL> select OBJECT_SCHEMA, OBJECT_NAME, POLICY_NAME,
POLICY_COLUMN, POLICY_COLUMN_OPTIONS, ENABLED,
SEL, INS, UPD, DEL
from DBA_AUDIT_POLICIES;
