Which two statements are true for crsctl and srvctl?
A.
crsctl is used to manage resources defined in the OCR
B.
srvctl can manage Clusterware daemons
C.
crsctl is used to manage CSS and CRS
D.
only srvctl can manage nodeapps
E.
srvctl is used to determine the status of Clusterware installation
Explanation:
C:
* CRSCTL is an interface between you and Oracle Clusterware, parsing and calling Oracle
Clusterware APIs for Oracle Clusterware objects.
* CSS- Cluster Synchronization Services – a daemon process that is used for synchronization
between different RAC nodes and synchronization between ASM and Oracle database instances.
* CRS – Oracle Clusterware is run by Cluster Ready Services (CRS)
D: SRVCTL Node-Level Tasks
The node-level tasks are:
Adding and deleting node level applications.
Setting and unsetting the environment for node-level applications.Administering node applications.
Administering ASM instances.
Starting and stopping a group of programs that includes virtual IP addresses, Listeners, Oracle
Notification Services, and Oracle Enterprise Manager agents (for maintenance purposes).
Note: The Server Control (SRVCTL) utility is installed on each node by default. You can use
SRVCTL to start and stop the database and instances, manage configuration information, and to
move or remove instances and services. You can also use SRVCTL to add services. SRVCTL
also manages configuration information.
Some SRVCTL operations store configuration information in the Oracle Cluster Registry (OCR).
SRVCTL performs other operations, such as starting and stopping instances, by sending requests
to the Oracle Clusterware process (CRSD), which then starts or stops the Oracle Clusterware
resources.
