    Hello Christian,

    the parameter SGA_TARGET is "not longer" supported by SAP.

    Take a look at sapnote #828268

    At the beginning of oracle 10g we have activated the ASMM ... but there is still a bug with oracle 10g which results in a hang situation (solved in 11g ... no backport planned)

    For more information regarding to the bug... take a look at bugnotes on metalink 4466399/4472338

    SGA_MAX_SIZE should be a little bit higher than the sum of all your memory pools (SGA), because of you can extend some areas dynamically on the fly (if you are using a spfile).

    Regards

    Stefan
