Examine these commands:
$ srvctl add service -db racdb -service erp -serverpool srvpooll
- failovertype TRANSACTION -commit_outcome TRUE - replay_init_time 1800
- retention 86400 -notification TRUE -rlbgoal SERVICE_TIME -clbgoal SHORT
- failoverretry 30 - failoverdelay 10
$ srvctl start service - db racdb - service erp
Instances RACDB_1 and RACDB_2 run on host01 and host02, respectively.
Which three statements are true regarding the service erp?
A. Connections to the database using erp benefit from Application Continuity.
B. erp is configured for an administrator-managed RAC database.
C. Load Balancing Advisory (LBA) will be disabled for this service.
D. Connections to the database using erp benefit from Load Balancing.
E. Connections to the database using erp benefit from Transaction Guard.
Answer: A,D,E
Explanation/Reference:
Explanation:
A: To enable Application Continuity for Java, set the failovertype parameter to TRANSACTION.
D: -clbgoal {SHORT | LONG}
Connection Load Balancing Goal. Use a value of SHORT for this parameter for run-time load balancing, or if using an integrated connection pool.
E: Enable Transaction Guard through the -commit_outcome parameter. When it is set to TRUE, the commit outcome for a transaction is accessible after the transaction's session fails due to a recoverable outage.
Incorrect Answers:
C: Load Balancing Advisory (LBA) is set through -rlbgoal parameter. Set this parameter to SERVICE_TIME to balance connections by response time

NEW QUESTION NO: 12
Which task must be performed before running the OPatch utility to patch Oracle Grid Infrastructure 12c?
A. Stage the patch on the cluster nodes.
B. Update the PATH environment variable on each cluster node to point to the $ORACLE_HOME/OPatch directory.
C. Stage the patch on the cluster node where the OPatch utility will be executed.

NEW QUESTION NO: 13
Which four statements are true concerning the upgrading of Oracle Grid Infrastructure 12c?
A. The ORACLE_HOME environment variable must be set to the Grid Infrastructure home directory in the installation owner's environment.
B. The upgrade must be done in-place.
C. The upgrade must be done out of place.
D. Upgrade validation may be done using the Oracle Universal Installer which in turn invokes the built-in cluster verification utility.
E. The cluster verification utility cluvfy.sh can verify that the cluster is ready for an upgrade.
F. The ORACLE_SID environment variable must be set to the SID of the ASM instance in the installation owner's environment.
G. The cluster verification utility cluvfy.sh can generate fixup scripts to run on all nodes of the cluster.
Answer: A,C,E,G
Explanation/Reference:
Explanation:
A: Use the following command to start the installer, where the path you provide for the flag ORACLE_HOME is the location of the home directory from the earlier Oracle Clusterware installation For example:
$ cd /u01/app/12.1.0/grid/oui/bin
$ ./runInstaller -nowait -waitforcompletion -ignoreSysPrereqs -updateNodeList -silent CRS=true ORACLE_HOME=/u01/app/crs
C: Oracle Clusterware and Oracle ASM upgrades are always out-of-place upgrades. You cannot perform an in-place upgrade of Oracle Clusterware and Oracle ASM to existing homes.
E, G: Run the CVU manual script cluvfy.sh script to perform system checks and generate fixup scripts Incorrect Answers:
A, F: For the installation owner running the installation, if you have environment variables set for the existing installation, then unset the environment variables $ORACLE_HOME and $ORACLE_SID, as these environment variables are used during upgrade. For example:
$ unset ORACLE_BASE
$ unset ORACLE_HOME
$ unset ORACLE_SID
D: You can run upgrade validations in one of two ways:
Run OUI, and allow the CVU validation built into OUI to perform system checks and generate fixup

scripts
Run the CVU manual script cluvfy.sh script to perform system checks and generate fixup scripts.

$ srvctl stop instance -db prod -instance " PROD1, PROD2 " -stopoption
immediate -f
Which statement is true about the outcome of this command?

B. It shuts down PROD1 and PROD2; OLTP will not be started on PROD3.
C. PROD1and PROD2 are not shut down because OLTP must first be manually relocated to PROD3.
D. PROD1and PROD2 are not shut down because OLTP must first be stopped.
E. It shuts down PROD1 and PROD2; OLTP will be started automatically on PROD3.
Answer: E
