CREATE VIEW RAISES ORA-03113 ON SESSION LEVEL AND 7445[QCDLGTD] WITHIN ALERT
(Doc ID 602111.1)
Last updated on NOVEMBER 28, 2016
Applies to:Oracle Server - Enterprise Edition - Version: 22.214.171.124.0
This problem can occur on any platform.
not been raised as a bug but instead is covered here with a recommended workaround
should the same situation be seen for other users.
Please be aware that whilst this Internal error in this situation does not correlate to any invalid
data or result in any impact beyond session termination it MUST NOT be implemented on
anything other than a TEST instance/machine and appropriate backups should always be taken
in advance of this type of testing.
The symptoms are :-
a) CREATE or REPLACE view : Performed on non SYS schema and on a SYS DBA view eg DBA_ROLE_PRIVS
b) CREATE fails at session level with ORA-03113 and session is disconnected
c) ORA-07445 reported in alert similar to :-
ORA-07445: exception encountered: core dump [qcdlgtd()+265] [SIGSEGV]
[Address not mapped to object] [0x000000000]  
However some platforms will not show a failing function so the tracefile also needs to be
d) Stack in trace file will be similar to :-
Function List (to Full stack) (to Summary stack)
ksedmp <- ssexhd <- sigacthandler <- qcdlgtd <- qcsfplob <- qcsprfro <- qcsfpaj <- qcsprfro <- qcsfpaj <- qcsprfro <- qcsfpaj <- qcsprfro <- qcsfpaj <- qcsprfro <- qcsfpaj <- qcsprfro <- qcspafq <- qcspqb <- kkmdrv <- rpiswu2 <- opiSem <- opiprs <- kksald <- rpiswu2 <- kkslod <- kglobld <- kglobpn <- kglpim <- kglpin <- kksfbc <- kkspsc0 <- opiosq0 <- opipls <- opiodr <- rpidrus <- skgmstack <- rpidru <- rpiswu2 <- rpidrv <- psddr0 <- psdnal <- pevm_EXIM <- pfrrun <- peicnt <- kkxexe <- opiexe <- opiall0 <- kpoal8 <- opiodr <- ttcpip <- opitsk <- opiino <- opiodr <- opidrv <- sou2o <- main <- start
QCDLGTD must be seen in alert or trace for this article to be considered.
e) Also in stack trace file we will see evidence of an object not existing ie NEXS status :-
