    Hi Raj,

    You need to run SGEN on the main Server and refresh the memory buffers

    on the application servers if its required but I assume this is

    automatically performed anyway so as the program buffers, PXA,

    are all in sync.


    From the tcode itself here is the info. on Parallel Generation

    2. Select Server for Parallel Generation.

    The generation is based on a parallelized method, where the generation

    set is divided into small subsets that are processed by parallel process

    Depending on resources, available servers are included in the parallel

    processing, whereby multiple parallel processes run on one server.

    From the Selection of Server for Parallel Generation screen, you can

    select the servers that are to be used in the parallel processing.

    Note that loads depend on the machine type (MT) of a host.

    This means that it only makes sense to parallel process the

    generation set of servers of the same machine type.

    The default selection orientates itself by the server to which it

    is logged on. It corresponds to your logon server and all servers

    on your system that have the same machine type. If you want to use

    the default selection, choose Continue.

    If you want to exclude individual servers from the generation, or

    if you want to generate the load for a particular machine type

    that is different to that of the logon server, then use the

    pushbutton to select the corresponding servers and choose Continue.

    Note: The parallel servers are depicted via the logon groups in

    transaction RZ12. For transaction SGEN, logon group 'parallel_generators

    is created. Do not use this group for your own purposes, as transaction

    SGEN uses and continually redefines this group.

    From the selection of the servers, the system starts to automatically

    define the generation set, and to store it on the database

    (DB table GENSETC).

    This may take several minutes.


    Thank You.

    There is no different procedure to RUN SGEN in IDES.

    FOr ECC 6.0 EHP4 IDES it and that too your 2 GB RAM,I guess it will take 4-5 days time.

    I had the similar experience with 4 GB RAM, it took 3 days.
