Which RDBMS version/release ? I found Data Guard documentation quite sufficient. Actually I never used anything else but the official docs and few MOS notes. Links to the docs for 10.2.x (if you are interested in different database version/release search for the correspondent docs on http://tahiti.oracle.com): Creating Logical Standby Database http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/create_ls.htm#SBYDB00300 Managing Logical Standby Database http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/manage_ls.htm#SBYDB00800 The following MOS Notes are useful for troubleshooting: 215020.1, 233519.1, 233261.1, 241512.1 ~Mihajlo **
