Mark, Folks We are also facing a similar issue with our "Banking" Application product where approx 1/3rd of the Database size is taken up by 1 Table which stores the Customer Signatures in one of its LONG/LOB fields. Database Sizes are in the range of a few Tera Bytes. The Banking Product is a primarily Pro C Application, with java functions too. Qs When accessing the Signature, in case compression techniques are used, is there a certain performance impact? SOME ADDITIONAL QUESTIONS ARE EMBEDDED BELOW IN CAPITALS. Thanks indeed -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Mark Strickland Sent: Friday, September 29, 2006 3:33 AM To: oracledba.williams@xxxxxxxxx Cc: dubey.sandeep@xxxxxxxxx; ORACLE-L Subject: Re: Storing blobs in database vs filesystem We're seriously considering doing the same thing. Out of 1.6-Tb, we have 1.3-Tb in LONGs, LONG RAWs and CLOBs that we're probably going to move out of Oracle. We're reaching a tipping point where we'll soon have to buy more SAN storage, multiplied by three (physical standby and full copy for Staging environment). I'm very interested in seeing other replies, ie, horror stories, gotchas, etc. We're also testing compressing the LONGs and CLOBs before they're inserted into the database and engineering the application to compress/uncompress in flight. * IF YOU COULD POSSIBLY SHARE YOUR APPROACH, ALGORITHM OR SOME SAMPLE FUNCTIONS FOR COMPRESSING LONGS/CLOBs "IN-FLIGHT"? * ARE YOU USING SOME STANDARD ORACLE COMPRESSION FEATURES / FUNCTIONS? * ANY SAMPLE COMPRESSION JAVA/ C FUNCTIONS? * ANY LINKS , DOCS WILL HELP Regards, Mark Strickland Seattle, WA **************** CAUTION - Disclaimer ***************** This e-mail contains PRIVILEGED AND CONFIDENTIAL INFORMATION intended solely for the use of the addressee(s).
