    RMAn backup time increasing.

    I am seeing increase in my backup time. I am using RMAN backup. If I recycle the database it works fine, but over a period of time the backup time starts increasing.
    After restarting the database, backup can be done in 3-4 hours, but after few days it may take 18-20 Hours.

    I am on Windows 2000, Oracle 8173, database size is around 200GB.

    Any Clues...........

    Hi,
    could it be that some resources will not get free
    for example increasing number of sessions due to
    ApplicationServer holding them ...
    Check V$sesstat for memory-usage of the sessions.
    Hope it's not a Win2K-problem.

    * Also look at oracle.exe in the taskmamanger, increases the memory-usage? day by day ?
    * Look to the memory-usage befor and after rman.backup.
    * will the rman-sessions terminated when backup finished
    * Also look on the size of the system-cache, and use of the memory on win2k (virtual + real )
