    <DS:TRAN.RZ12>Perform function</>
    &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.

  • What is the cause and solution for SAP error message SPTA005 - No resources available for server group &v1 ?

    The SAP error message SPTA005 indicates that there are no resources available for the specified server group. This error typically occurs in the context of SAP's background processing or when trying to execute jobs that require specific server resources.

    Cause:

    1. Resource Allocation: The server group specified does not have any available resources (e.g., application servers) to handle the request.
    2. Server Group Configuration: The server group may not be properly configured or may not have any active servers assigned to it.
    3. System Load: The system may be under heavy load, causing all available resources to be occupied.
    4. Maintenance Mode: Some servers in the group may be in maintenance mode or down for other reasons.
    5. Network Issues: There could be network connectivity issues preventing access to the servers in the group.

    Solution:

    1. Check Server Group Configuration:

      • Go to transaction SMLT (for logical system configuration) or SMLT (for server group configuration) and verify that the server group is correctly set up and that there are active servers assigned to it.
    2. Monitor System Load:

      • Use transaction SM50 or SM66 to monitor the workload on the application servers. Check if the servers are busy and if there are any jobs queued.
    3. Check Server Status:

      • Use transaction SM51 to check the status of the application servers. Ensure that the servers in the group are up and running.
    4. Review Job Scheduling:

      • If the error occurs during job scheduling, check the job definition and ensure that it is correctly assigned to the appropriate server group.
    5. Adjust Resource Allocation:

      • If necessary, adjust the resource allocation for the server group or redistribute the workload among different server groups.
    6. Check for Maintenance:

      • Ensure that no servers in the group are undergoing maintenance or are intentionally taken offline.
    7. Consult Logs:

      • Check the system logs (transaction SM21) for any additional error messages or warnings that might provide more context about the issue.
    8. Contact Basis Team:

      • If the issue persists, it may be necessary to involve the SAP Basis team to investigate further, especially if it relates to system configuration or performance tuning.
