    All,
    Do i need to configure backup_tape_io_slaves for rman to use large pool ? I''ve setup large pool but it is not being used at all (queried v$sgastat for free memory) and it is the same as total memory initialised. Any inputs ?
    OS is Solaris 2.6 and Oracle version is 8.1.7

    Thanx

    LARGE_POOL is only used if I/O Slaves are specified by DISK_IO_SLAVES or BACKUP_TAPE_IO_SLAVES.

    Moreover, you cannot perform duplexed backups with backup_tape_io_slaves set to true.

    Thanx. in that case i'm better off without large pool coz my SGA is sized large enough for backup and restores.

    Well, you may set BACKUP_TAPE_IO_SLAVES = TRUE and allocate some megas for the large pool size. I do that. Then forget about duplexed backups :-)
