Oracle 10g to 12c with Dataguard

396 Views

As per my original question https://archive.sap.com/discussions/thread/3888922 I have come to now do the upgrade only to find I have an error.

I came to start mount the standby database after installing and patching Oracle 12c but was greeted with

SQL> startup mount
ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file '/oracle/SID/121/dbs/initSID.ora'

So I thought ok I'll copy the original one over to that location and try again only to be greeted with another error.

SQL> startup mount
ORA-32004: obsolete or deprecated parameter(s) specified for RDBMS instance
ORA-00401: the value for parameter compatible is not supported by this release

What do I do?
