Question

Hi,
Oracle Ver: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production
Os:Win Xp
I am trying to create a Standby through Rman....
I am using this Run Block to take backup of Primary Database.......
run {
allocate channel d1 type disk;
allocate channel d2 type disk;
setlimit channel d1 kbytes 2097150;
setlimit channel d2 kbytes 2097150;
backup incremental level 0 format 'e:\Oracle\standby\rman\df_%U' database
include current controlfile for standby;
sql "alter system archive log current";
backup
archivelog all format 'e:\Oracle\standby\rman\al_%U' delete input;
}After taking the Backup when I am trying to create the standby with Duplicate command it s giving me Error...
The Run Block I am using is ......
RMAN> run {
2> allocate auxiliary channel dup1 type disk;
3> allocate auxiliary channel dup2 type disk;
4> set newname for datafile 1 to 'E:\Oracle\standby\system01.dbf';

Answer 1

Check the value for the parameter "COMPATIBLE" in the source and standby database instance parameter files.
"COMPATIBLE" should be the same.
See http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/create_ps.htm#i70517
"... ensure the COMPATIBLE initialization parameter is set to the same value on both the primary and standby databases"
