&DEPENDENCIES&
If one of the following criteria is exceeded, an application server
provides <zh>no resources</>:
<zh>number of free dialog work processes</>
These are provided as available resources by the application server. A
certain number of dialog work processes are retained by default as
reserve instances for other purposes, e.g. system logon or
administration programs. The default value is 1 and can be specified in
the profile parameter <zh>rdisp/rfc_min_wait_dia_wp</>.
<zh>proportion of user dialog work processes</>
The default value is 75% of all dialog work processes. This value can
be specified in the profile parameter <zh>rdisp/rfc_max_own_used_wp</>.
The number of dialog work processes is specified in the profile
parameter <zh>rdisp/wp_no_dia</>.
<zh>proportion of the waiting requests in the dialog queue</>
The default value is 5% of the total dialog queue length.
This value can be changed in the profile parameter
<zh>rdisp/rfc_max_queue</>.
The length of the dialog queue is determined by the profile parameter
<zh>rdisp/elem_per_queue</>.
<zh>proportion of logons in system</>
The default value is 90%. If the proportion of logged on users is
greater, no resources are released.
This value can be changed by the profile parameter
<zh>rdisp/rfc_max_login</>.
The maximum number of logons to a server is set in the profile
parameter <zh>rdisp/tm_max_no</>.
<zh>number of user logons in system</>
The default value is 25% of all logoons. This value can be changed by
the profile parameter <zh>rdisp/rfc_max_own_login</>. Each RFC logs on
to the target system.
<zh>proportion of communication entries used</>
Each server has a limited number of communication channels. The default
limit is 90%.
This value can be changed by the profile parameter
<zh>rdisp/rfc_max_comm_entries</>. The maximum number of communication
channels is determined by the profile parameter
<zh>rdisp/max_comm_entries</>. An entry is made for the client and the
server for each connection.
&HINTS&
An application server <ZH>must</> have at least 3 free dialog processes
to be able to be used for RFC parallel processing.
