are you using enterprise edition and is it feasible to use partitioning?, if you partition on the field that defines "older than 12 months", its easy enough to drop a partition(or exchange a partition with a non-partitioned table, export that and drop it.

hi there is this project that is going on for archiving old data from oltp system that is older than 12 months and then purging them in the main db.
the tables that are to be archived are with long rows. they cannot be converted to lobs since this is a third party application. here is where the problem lies. oracle support when contacted says either mv to lobs to make this move easier or use oci ..blah.blah.. to get this working if you want to remain in longs.
there are some options i have though about: 1. export /import ..but should make this highly automated since the main db and archival db will be on different hosts, this will not be monitored and import has to go thru w/o issues etc. 2. create snapshot - but they dont work with long..hence not an option. 3. getting sqlldr to work but i think it has that 32k column size limitation.
so can you please suggest me whetehr there is something else i can do or option 1 is the best given the environment. the oracle is 8.1.7.2 on sun 2.8.
thanks
sai
