Tom Tom, To solve the error "out of resources" in AIX you need to configure the environment variavle IFMX_AIXKAIO_NUM_REQ, there are no problems to run IDS in AIX 5.3 or AIX 6.1, check this option with IBM Support Center. In IDS11 there are many new features to help you , like Direct I/O to bypass double buffering , maybe you can use this feature instead of raw volumes. Vagner
