hi, friends,
We have a few database which stores archived data, it become huge in the past few years, as big as 100TB+.
We have used compress table to reduce size for non-long/long raw tables and it helps reduce size to 1/3-1/6 with proper sort during CTAS. But 50%+ of the data are actually with LONG column. Two questions; 1. With 11g secure lob compression, anyone has experience with that? We can consider upgrade to 11g if that really helps. 2. Any solution outside of database? Like at Host/SAN layer... We considered ZFS (we are on Sun) and SAN team declined the idea.
Any comment/experience is welcome. Thanks.
