$DCDIR/lib/sysconf/mcf max_socket_descriptors The definition must be reviewed when the number of UAPs that request message transmission from the MCF communication process and the number of operation commands that issue processing requests concurrently increase.
MCF manager common definition mcfmcomn -c The definition must be reviewed when an SPP that performs synchronous transmission is added.
mcfmcomn -p The definition must be reviewed when an MHP is added.
If the value must be increased, the amount of the increase is added to the value of the static_shmpool_size operand in the system environment definition (env).
Extended reservation definition mcfmexp -g The definition must be reviewed when an extended reservation definition has been defined and a new MHP service group is added.
Status inheritance definition mcfmsts -g The definition must be reviewed when the number of service groups whose status is inherited increases.

mcftsts -a The definition must be reviewed when an MHP that inherits the status is added.
Definition of a logical terminal that starts applications mcftalcle -m The definition must be reviewed when a user server that starts applications is added.

The following table lists the OpenTP1 files that must be reviewed when a server is added and indicates under what conditions a review is required.
