Which two Cluster ware stack administration actions must be performed as the root user?

checking the health of the Clusterware on one node
starting the Clusterware manually on one node
disabling the Clusterware from automatic start at node reboot
checking the health and viability of the Clusterware on all nodes
listing the location of the voting disks

Correct answer: BC

Explanation:

Controlling Oracle Clusterware The crsctl utility can be used to control Oracle Clusterware. To start or stop Oracle Clusterware on a specific node:# crsctl start crs # crsctl stop crs To enable or disable Oracle Clusterware on a specific node:# crsctl enable crs # crsctl disable crs D60488GC11 Oracle 11g: RAC and Grid Infrastructure Administration Accelerated 3 - 5

Controlling Oracle Clusterware

The crsctl utility can be used to control Oracle Clusterware.

To start or stop Oracle Clusterware on a specific node:

# crsctl start crs

# crsctl stop crs

To enable or disable Oracle Clusterware on a specific node:

# crsctl enable crs

# crsctl disable crs

Which four statements are true about ADVM interoperability?

Using fdisk or similar disk utilities to partition ADVM-managed volumes is not supported
On Linux platforms, the raw utility can be used to map ADVM volume block devices to raw volume devices.
The creation of multipath devices over ADVM devices is not supported.
You may create ASMLIB devices over ADVM devices to simplify volume management.
ADVM does not support ASM storage contained in Exadata.
F. ADVM volumes cannot be used as a boot device or a root file system.

Correct answer: ACEF

Explanation:

Oracle Automatic Storage Management Cluster File System (Oracle ACFS) and Oracle ASM Dynamic Volume Manager (Oracle ADVM) extend Oracle ASM support to include database and application executables, database trace files, database alert logs, application reports, BFILEs, and configuration files. Other supported files are video, audio, text, images, engineering drawings, and other general-purpose application file data. Because of the fact that Oracle ADVM Volumes are technically spoken ASM files located on ASM Disk groups, and the fact that the Dynamic Volumes do not use the traditional device partitioning, it enables Oracle to extend some of the ASM features to the ASM Clustered File Systems, which are created inside these ADVM Volumes, such as dynamic resizing or dynamically adding volumes. This makes ADVM and ACFS a far more flexible solution than traditional physical devices. Important Notes:

Important Notes:

Your four-node cluster was originally purchased, installed, and configured three years ago. You recently added another four nodes to the cluster.

Now you want to remove two of the older nodes that are still accessible to be redeployed elsewhere in the data center.

Which two are true regarding the procedure for removing one or more cluster nodes?

The procedure requires that all commands be invoked from one of the surviving cluster nodes.
All commands are run as root regardless of which nodes are used to invoke them.
The procedure requires that some commands be invoked on the node or nodes to be removed and that some be invoked from all surviving cluster nodes.
The procedure requires that some commands be invoked on the node or nodes to be removed and that some be invoked from one surviving cluster node.
Some commands require that the name of the node or nodes to be removed are passed as arguments, and some commands require the name of existing nodes to be passed.

Correct answer: DE

Explanation:

# crsctl delete node -n node_to_be_deleted $ ./runInstaller -updateNodeList ORACLE_HOME=Grid_home "CLUSTER_NODES={node_to_be_deleted}" CRS=TRUE -silent -local On any node other than the node you are deleting, run the following command from the Grid_home /oui/bin directory where remaining_nodes_list is a comma-delimited list of the nodes that are going to remain part of your cluster:$ ./runInstaller -updateNodeList ORACLE_HOME=Grid_home "CLUSTER_NODES={remaining_nodes_list}" CRS=TRUE -silent $ cluvfy stage -post nodedel -n node_list [-verbose] Oracle® Clusterware Administration and Deployment Guide

# crsctl delete node -n node_to_be_deleted

$ ./runInstaller -updateNodeList ORACLE_HOME=Grid_home "CLUSTER_NODES={node_to_be_deleted}" CRS=TRUE -silent -local

On any node other than the node you are deleting, run the following command from the Grid_home /oui/bin directory where remaining_nodes_list is a comma-delimited list of the nodes that are going to remain part of your cluster:

$ ./runInstaller -updateNodeList ORACLE_HOME=Grid_home "CLUSTER_NODES={remaining_nodes_list}" CRS=TRUE -silent

$ cluvfy stage -post nodedel -n node_list [-verbose]
