**To describe extension pack associations**

The following ``describe-extension-pack-associations`` example retrieves the status of operations that apply an extension pack to the target database, identified by their request IDs. ::

    aws dms describe-extension-pack-associations \
        --migration-project-identifier arn:aws:dms:us-east-1:123456789012:migration-project:EXAMPLEABCDEFGHIJKLMNOPQRS \
        --filters Name=request-id,Values=a1b2c3d4-5678-90ab-cdef-EXAMPLE11111,a1b2c3d4-5678-90ab-cdef-EXAMPLE22222,a1b2c3d4-5678-90ab-cdef-EXAMPLE33333

Output::

        "Requests": [
            {
                "Status": "SUCCESS",
                "RequestIdentifier": "a1b2c3d4-5678-90ab-cdef-EXAMPLE11111",
