We recently upgraded SAP R/3 4.7 ext 200 Oracle 10g to 11g on production server and now plan to upgrade the DR server which is running on 10g. Is there a possibility to upgrade Oracle directly as how its being done on production server? Reason being upgrade will not run fundamentally if the database is not open which in this case DR which is on Oracle dataguard is only or standby database mode.
Please advise and I'd really appreciate it.
