Which two statements are true about server categorization in Oracle 19c Clusterware? (Choose two.)
Which two statements are true about server categorization in Oracle 19c Clusterware? (Choose two.)
Different nodes in a cluster may belong to separate administrator-defined categories, allowing for flexible management based on specific roles or characteristics. All server attributes used for categorization are modifiable by administrators, enabling the customization of categories to meet unique clustering requirements. This flexibility supports efficient cluster management and aligns resource allocation with organizational needs.
A is correct because Oracle Clusterware allows administrators to define different categories and assign nodes to these categories based on the roles or characteristics of the servers. E is correct because the attributes used to categorize servers can be modified by administrators to suit their specific clustering requirements. Incorrect statements: B is incorrect because not all nodes in a cluster must belong to the same Oracle-supplied category; administrators can create custom categories. C is incorrect because a server can belong to multiple categories. D is incorrect because while Oracle Clusterware can discover some server attributes automatically, administrators can also manually set and modify these attributes. F is incorrect because server categories are not limited to nodes running an application server; they can be used for various types of nodes within the cluster.
Administrators can create different categories based on specific attributes and assign different servers to them. This allows for the creation of heterogeneous nodes within a cluster, and facilitates workload isolation and resource agility. A server may be added to only one category using the crsctl utility. This statement is correct
