    Hi,
    If u want to take a export of the table which is 10GB in size then i think that u should

    exp sys@plan_mts file=a.dmp log=a.log tables=user.bigtable
    indexes=y rows=y consistent=y(read only view from rollback segment) statistics=none
    compress=N constraints=y
    direct=y(bypasses SQL command Processing Layer)


    In case of any help please be free to ask me at rohitsn@altavista.com

    Most of the OS wil not support > 2 GB file size. To split the dump file, you need to use filesize parameter in the exp command.

    I do an export of few of my tables daily, which are as big as 6GB.I use the direct =y option and put them in a partition where there is about 12GB disk space.

    I do the exports of such big tables every day as a backup strategy. I cannot put these tables into archive mode as the redo logs will fillup the file system.



    exp file=exp_${ORACLE_SID}_${expdate}.dmp Tables=rei_usage_history consistent=y direct=y statistics=none log= /u01/app/oracle/product/8.1.6/admin/rel/exp/logs/exp_${ORALCE_SID}_${expdate}.log>/dev/null 2>&1


    This works
