It requires the cdb to use shared undo management.Question # 3 Which two benefits are obtained by using Affinity to reduce global resource contention? (Choose two.) A. Oracle RAC affinity for partitioned tables routes all database requests for a partition tables to a single Oracle RAC instance leading to higher Oracle RAC performance and scalability because of improved cache locality and reduced internode synchronization and block pings of the partition tables.B. Oracle RAC affinity for partitioned tables routes database requests to Oracle RAC instances in such a way that each instance always gets requests for a disjoint subset of rows in the database, this affinity leads to higher Oracle RAC performance and scalability because of improved cache locality and reduced internode synchronization and block pings.C. Oracle RAC affinity for partitioned tables routes database requests to all available Oracle RAC instances evenly to create a global affinity in such a way that each instance always gets an even number of requests leading to higher Oracle RAC performance by using a higher levels of available global cache to reduce global resource contention.D. To enhance the performance of distributed transactions with applications server that provides XA affinity, you can automatically spawn new dedicated database RAC instances to isolate distributed transaction.E. To enhance the performance of distributed transactions with applications server that provides XA affinity, you can direct all branches of a distributed transaction to a single instance in the cluster to improve cache locality and reduce internode synchronization and block pings.

The oracle SID environment variable must be set to the SID of the ASM instance in the installation owner's environment.D. The oracle home environment variable must be set to the Grid Infrastructure home directory in the installation owner's environment.E. The upgrade must be done in-place.

A. When possible, clients with the samecolocation_tagare routed to the same instance that offers a given service.B. When possible, clients with the samecolocation_tagare routed to the same available instance even if a preferred instance is available.C. When possible, clients with the samecolocation_tagcould be routed across a set of preferred instances based on a specific load balancing option.D. When possible, clients with the samecolocation_tagare routed to the same available instance when a preferred instance is not available.

A. When possible, clients with the samecolocation_tagare routed to the same instance that offers a given service.Question # 6 Which two steps must always be performed to delete nodehost04from an Oracle 19c Clusterware cluster that does not use Grid Naming Service (GNS)? (Choose two.) A. Run the crsctl unpin css - host04 command as root on host01, or on either host02 or host03.B. Run the crsctl delete node -n host04 command as root on host04.C. Run the crsctl delete node -n host04 command as root on host01, or on either host02 or host03.D. Run the crsct1 unpin css - host04 command as root on host04.E. Run the rootcrs.pl -deconfig -force command as root on host04.
