Which three programs or utilities can be used to convert a single-instance database to a Real Application Cluster database?

• A.the RCONFIG utility
• B.the CRSCTLl utility
• C.DBCA
• D.Enterprise Manager
• E.the SRVCTL utility

A policy-managed RAC database that hosts the ACCOUNTS service has only three instances running rather than the usual four on a six-node cluster.
Five of the six cluster nodes are active and the sixth (RACNODE6) is down for maintenance.
You decide to check the state of the servers in the server pools to see if there are problems with the OLTP pool to which the ACCOUNTS service has been assigned.
You used the crsctl status server-f command and see that the RACNODE3 node has STATE=VISIBLE.
What is true about this situation?

• A.The Cluster Ready Services Daemon (crsd) is running and RACNODE3 is considered to be a part of the cluster, but the Cluster Synchronization Services Daemon (cssd) is currently not running.
• B.Both the Cluster Ready Services Daemon (crsd) and the Cluster Synchronization Service Daemon (cssd) are running on RACNODE3, but RACNODE3 is currently being moved to another server pool.
• C.Neither the Cluster Ready Services Daemon (crsd) nor the Cluster Synchronization Services Daemon (cssd) is running on RACNODE3.
• D.The Cluster Synchronization Services Daemon (cssd) is running and RACNODE3 is considered to be part of the cluster, but the Cluster Ready Services Daemon (crsd) is currently not running.

You need to set up a three-Instance RAC database. The data files and fast recovery area will be stored in ASM diskgroups called +data and +fra, respectively. The ASM disk groups will be mounted on all ASM Instances.
Which are the two best location options for archivelogs so that they can be accessed during recovery without DBA intervention?

• A.the ASM diskgroup +fra with the db_recovery_file_dest parameter set to the same value on all instances
• B.Cluster File System with each instance writing to a shared location
• C.a raw or block device
• D.Cluster File System with each instance writing to a separate location as long as all the locations are in directories under the same mount point

You are managing a single-instance database and your company wants to convert the single instance database to an Oracle RAC database. You plan to use the rconfig utility to accomplish this task.
What are the prerequisites for converting the single-instance database to an Oracle RAC database?

• A.Oracle Clusterware and Oracle Database software are installed on all target nodes.
• B.The Oracle Database binary is enabled for Oracle RAC on all target nodes.
• C.Oracle Clusterware is stopped.
• D.Automatic Storage Management (ASM) must be enabled and the ASM disk should be available on all nodes.
• E.The database being converted has been backed up successfully.

Which two statements are true regarding the Active Session History (ASH) reports for RAC?

• A.They provide statistics about Oracle databases for the active sessions on all the RAC nodes.
• B.They report on data captured for active sessions. The volume of data is directly related to the work being performed by sessions.
• C.They provide details about Oracle databases for all current sessions, and history of past session all RAC nodes.
• D.They report on data captured for active sessions. The volume of data is directly related to the number of sessions on the system.
