Hi!
I prefer v$bgprocess to X$ tables, primarily because I can query it from
any user, not just SYS
For TMON v$bgprocess says the following:
SQL> select name,type, description from v$bgprocess where lower(name)
2 like '%tmon%';
NAME TYPE DESCRIPTION
----- -----
----------------------------------------------------------------
TMON Transport Monitor
Elapsed: 00:00:00.00
SQL>
The x$ksbtabact table gives the following result:
select PROCESS_NAME_KSBTABACT as PNAME, ACTION_DESCRIPTION_KSBTABACT
as ACTIONS
2 from X$KSBTABACT
3 where lower(PROCESS_NAME_KSBTABACT) like '%tmon%';
PNAME
----------------------------------------------------------------
ACTIONS
----------------------------------------------------------------
TMON
KSB action for X-instance calls
TMON
KSB action for bast checking
TMON
generic shutdown background
TMON
ksim instance group membership notifier
TMON
KSB action for ksbxic() calls

The v$bgprocess gives me the idea what the process is about: monitoring
my data guard configuration. Unfortunately, such information can no
longer be found at MOS.

Hello Nenad,
just for completeness. There is a x$ table which lists all the actions/tasks
regarding background processes.
SQL> select PROCESS_NAME_KSBTABACT as PNAME, ACTION_DESCRIPTION_KSBTABACT as
ACTIONS
from X$KSBTABACT
order by PNAME, ACTIONS;
