Is it any possible creating standby DB with different version(11.2.0.4) to primary DB(12.2.0.1.0
My primary DB version is 12.2.0.1.0 and I try to created physical standby DB in another server with the version 11.2.0.4. I can restore/recovery the Standby DB via RMAN, but if I try to run "alter database open read only;" , I encountered error as below:
SQL> alter database open read only;
alter database open read only
*
ERROR at line 1:
ORA-01092: ORACLE instance terminated. Disconnection forced
ORA-00704: bootstrap process failure
ORA-39700: database must be opened with UPGRADE option
Process ID: 161403
Session ID: 581 Serial number: 13
So, I try to switch it to R/w DB, the active step is ok:
SQL> alter database activate standby database;
