Dependencies

If one of the following criteria is exceeded, an application server provides no resources:

  • 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 rdisp/rfc_min_wait_dia_wp.
  • 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 rdisp/rfc_max_own_used_wp. The number of dialog work processes is specified in the profile parameter rdisp/wp_no_dia.
  • 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 rdisp/rfc_max_queue.
    The length of the dialog queue is determined by the profile parameter rdisp/elem_per_queue.
  • 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 rdisp/rfc_max_login.
    The maximum number of logons to a server is set in the profile parameter rdisp/tm_max_no.
  • number of user logons in system
    The default value is 25% of all logoons. This value can be changed by the profile parameter rdisp/rfc_max_own_login. Each RFC logs on to the target system.
  • 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 rdisp/rfc_max_comm_entries. The maximum number of communication channels is determined by the profile parameter rdisp/max_comm_entries. An entry is made for the client and the server for each connection.

Notes

An application server must have at least 3 free dialog processes to be able to be used for RFC parallel processing.
