Cache=file
    Nocache

    Specifies an after-image journal cache file specification on a
    solid-state disk. If the Cache qualifier is specified, after-
    image journal caches are enabled. If you specify a file name, but
    not a file extension, the file extension .aij is used by default.

    If the Nocache qualifier is specified, AIJ caches are disabled.
    You can use this qualifier only when users are detached from the
    database.

    This file must be written to a solid-state disk. If a solid-state
    disk is not available, after-image journal caching should not be
    used. Unless you are involved in a high performance, high-volume
    environment, you probably do not need the features provided by
    this qualifier.

    You can determine whether the cache file is accessible by
    executing the RMU Dump command with the Header qualifier. If
    caching is enabled, but the cache file is unavailable, the cache
    file is marked inaccessible and after-image journaling continues
    as if caching was disabled. Once the cache file has been marked
    inaccessible, it will remain so marked until either the existing
    cache file is dropped from the database, or a new cache file is
    added to the database (even if this is the same cache file as was
    previously used).

    If this qualifier is omitted, the AIJ cache state remains
    unchanged.
