Re: hot backup mode?
Posted in 1995
The hot backup mode (data replication) works only with Informix 6.0 and greater. The backup site should be set up similarly. One catch is that if your database has BLOBs, this solution will not work for you as Informix does not buffer BLOB transactions to the logical logs. Informix' data replication in version 6 is very twitchy and procedures to set up replication must be done with precise timing. One good feature with data replication is that you can use the 'hot backup' site to perform read-only transactions (DSS). If you are sticking with Informix 5.x, you can use triggers, stored procedures, and two-phase-commits to do data replication. However, this solution can be very time consuming to setup. ##################################################################### David Nguyen \\\\\\|||/// ---------- Internet: david_nguyen@notes.pw.com . ======= / Uh... \\ Price Waterhouse / \\| O O | / Just restore \\ 3110 Fairview Park Dr \\ / \\v_'/ <- from tape. / Suite 300 # _| |_ \\ / Falls Church, VA 22042 (#) ( ) ---------- (703) 641-5597 #\\//|* *|\\\\ #\\/( * )/ # ===== #include disclaimer.h # (\\ /) Blah, Blah, Blah. # || || .#---'| |----. #----' -----' #####################################################################
