Marco,

 

see this post:

VKTM - The virtual keeper of time provides wall-clock time and reference
time for other sessions/processes.

Apparently I missed something somewhere... 

 

Errors in file /oracle/diag/rdbms/test/TEST/trace/TEST_pmon_16980.trc:
ORA-56703: VKTM process died unexpectedly
Mon Sep 15 22:16:47 2008
Error occured while spawning process q001; error = 56703
PMON (ospid: 16980): terminating the instance due to error 56703
Mon Sep 15 22:16:53 2008
Termination issued to instance processes. Waiting for the processes to
exit
Instance termination failed to kill one or more processes
Mon Sep 15 22:17:15 2008
Instance terminated by PMON, pid = 16980

 

[oracle@srv trace]$ oerr ora 56703


56703, 00000, "VKTM process died unexpectedly"
// *Cause: An explicit kill or internal error caused the death of VKTM
//         background process.
// *Action: Restart the instance.

Apparently that this is serious enough, my instance crashed and to my
surprise without something like a ORA-0600 (maybe because "it is
handled..."), although I can imagine that this process, apparently with
dependencies with PMON, will cause the other important backgound
processes to shut down (if not already the case). 

 

For those who are interested this happened after trying to insert a lot
off big xml files into a binary xml xmltype, table which caused a lot of
ORA-04030, that caused job queue processes to die, that caused server
(shared server) processes to die, that signaled pmon to terminate the
instance.

 

 

So my question...

 

Does anyone know what a "VKTM" background process is...?
