    Log Archive Format

    beside this format below:

    log_archive_format = %%ORACLE_SID%%T%TS%S.ARC


    what is other good and short format can someone suggest me to use???

    the above format make the archive log file too long.

    If you are running more than 1 DB PLEASE make sure you uniquely identify the log files (ie by using the SID somewhere in the filename).

    Otherwise you're asking for trouble.

    Or use different directories (log_archive_dest).

    If you insist, something like:

    log_archive_dest = X:\%ORACLE_SID% <--- check this, never used a substitution myself here
    log_archive_format = A%S.%T

    is about as short as possible, while remaining generally unique.
    Could be shorter still if you can abandon the thread number.

    (Never seen %TS in this context - can't find it in the doc - what is it?)

    Whoaaaaa! are you talking about the length of the file name (as we all assumed - 'coz that's what this param does) or the SIZE of the file (in Kb)?

    The SIZE is determined by the size of the redologs. Archivelogs zip/compress quite nicely to save space.

    Dapi,

    sorry I mistyped.

    I mean the name of the archived log file NAME not the SIZE.

    Thanks
