    Re: ORA-04031: unable to allocate 8388608 bytes of shared memory ("large

    So do you have a large pool or not?

    In your init.ora you have:

    #large_pool_size=10485760

    Run:

    show parameter large

    and

    select * from v$version; and post here the output

    the key is shared_pool_size and restart the DB once you change it unlesss you're using spfile.

    The error message points rather to the large pool than the shared pool.

    Why are u killing ur SGA? ..

    Make it dedicated type, u will not see the error ..

    Note :

    * Is sort area size of 5GB really necessary ?
    * Is Shared Pool Reserved Space of 20M necessary ?
