You want to verify if the user's session has waited for certain types of I/O activity Which view displays all waits waited on by a session at least once?

The source and destination platforms have the same endian format.

Examine this list of steps:1. Make the UNIVERSIRY tablespace read-only on the source system2. Export the UNIVERSIRY tablespace metadata using EXPDP3. Create a cross-platform backup set from the UNIVERSITY tablespace on the source system, using an

RMAN command that includes the DAMAPUMP clause4. Copy the cross-platform backup sets to the destination system5. Copy the Data Pump dump set from the source to the destination system6. Restore the cross-platform backup set on the destination system using an RMAN command that includes the pamapump clause7. Import the UNIVERSIRY tablespace metadata using IMPDP8. Make the UNIVERSIRY tablespace read/write on the destination system

Which are the minimum number of steps required, in the correct order, to transport the UNIVERSIRY tablespace?
