Which task would you recommend before using the Database Upgrade Assistant (DBUA) to upgrade a single-instance Oracle 11g R2 database to Oracle Database 12c?
A.
shutting down the database instance that is being upgraded
B.
executing the catctl.pl script to run the upgrade processes in parallel
C.
running the Pre-Upgrade Information Tool
D.
copying the listener.ora file to the new ORACLE_HOME
C
For all upgrades, before using DBUA to upgrade your system, Oracle strongly recommends that you run the Pre-Upgrade Information Tool manually. DBUA runs the Pre-Upgrade Information Tool as part of the prerequisite checks it performs before starting the upgrade. However, to reduce downtime, Oracle recommends that you run the Pre-Upgrade Information Tool as part of your upgrade planning, so that you can analyze the database, and take proactive steps before your planned upgrade date.
