ALTER PROCESS
•
ONLINEDUMP
Description: An online dump process dumps audited database files to secondary
storage, such as tape or disk. It runs only while the dump is in progress. By
default, online dump processes are dynamically assigned to one or more
processors as needed. You can override the default by adding or removing
processors for this process type.
Process start-up: An online dump processes starts whenever the TMFCOM
DUMP FILES command is issued.
•
ONLINERESTORE
Description: An online restore process copies online dump files from archive
media to disk, on behalf of a file recovery process. By default, online restore
processes are dynamically assigned to one or more processors as needed. You
can override the default by adding or removing processors for this process type.
Process start-up: An online restore process starts whenever a file recovery
process requires that one or more online dumps be restored.
•
TMFMON
Description: A TMFMON (transaction manager monitor) process is responsible for
highest-priority, performance-critical operations on the processor. It is chiefly
responsible for allocating the memory segments used by TMFLIB data structures
and notifying the TMP when disk volumes come up and go down. A TMFMON
process runs in every processor on the node. You cannot override this processor
assignment.
Process start-up: The TMFMON processes start during processor cold-load, and
persist continuously in the system.
•
TMFMON2
Description: A TMFMON2 process is a surrogate process that creates the
transaction management process (TMP) and allocates the memory segments used
by TMFLIB. It also is responsible for resynchronizing TMFLIB data structures in
their processors after processor failure and reload. It also cleans up TMFLIB and
disk process data structures after a TMF crash or a STOP TMF, ABRUPT
command. A TMFMON2 process runs in every processor on the node. You
cannot override this processor assignment.
Process start-up: The TMFMON2 processes are started during processor cold-
load by their associated TMFMON processes, and persist continuously in the
system.
