Database rolling upgrade in a Data Guard scenarios | physru script vs. DBMS_ROLLING PL/SQL package
Dear HA Data Guard community,
We are lloking for guidance on upgrading Oracle Database 11.2.0.4 to Oracle Database 12.1.0.2 in a Data Guard scenario. We got from Support some details regarding rolling upgrades using a standby database:
Oracle Database Rolling Upgrades Using a Data Guard Physical Standby Database
http://www.oracle.com/technetwork/database/availability/database-rolling-upgrade-3206539.pdf
However, it's still not clear to us in this upgrading process scenario (from 11.2.0.4 to 12.1.0.2) whether we would be using the physru script (as indicated in above documentation) or the DBMS_ROLLING PL/SQL package.
Would you be so kind to give us official confirmation on this point? How would any of this options impact regarding Oracle Data Guar licensing?
