Hi all , I've been assigned mission to develop a script which create standby db from primary . I've seen this link http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14239/rcmbackp.htm#i636427 , which suggest to use RMAN with duplicate command. It's seems to be the most simple way . is anyone has expernice with that ? Anyhow , in oracle documentation it seems that the standby db has to have a different name . This doesn't make senesce to me , because this will required different connect string on the client side (after switchover) , I guess I'm missing something here ? For example if I can't set log_archive_config to use the one name SQL> alter system set log_archive_config='DG_CONFIG=(ora10)'; alter system set log_archive_config='DG_CONFIG=(ora10)' * ERROR at line 1: ORA-32017: failure in updating SPFILE ORA-16187: LOG_ARCHIVE_CONFIG contains duplicate, conflicting or invalid attributes thanks Amihay Gonen, DBA amihay.gonen@xxxxxxxxxxx<mailto:amihay.gonen@xxxxxxxxxxx>
