These functions enable you to perform the following operations:
Initialize the DSDL environment
Retrieve resource type, resource, and resource group names, and extension property values
Fail over and restart a resource group, and restart a resource
Convert error strings to error messages
Execute a command under a timeout
The following functions initialize the calling method:
scds_initialize(3HA) – Allocates resources and initializes the DSDL environment.
scds_close(3HA) – Frees resources that are allocated by scds_initialize().
The following functions retrieve information about zones, resource types, resources, resource groups, and extension properties:
scds_get_current_method_name(3HA) – Retrieves the last element of the path name by which a data service method was called.
scds_get_zone_name(3HA) – Retrieves the name of the zone on whose behalf a method is running.
scds_get_resource_type_name(3HA) – Retrieves the name of the resource type for the calling program.
scds_get_resource_name(3HA) – Retrieves the name of the resource for the calling program.
scds_get_resource_group_name(3HA) – Retrieves the name of the resource group for the calling program.
scds_get_ext_property(3HA) – Retrieves the value of the specified extension property.
scds_free_ext_property(3HA) – Frees the memory that is allocated by scds_get_ext_property().
The following function retrieves status information about the SUNW.HAStoragePlus resources that are used by a resource:
scds_hasp_check(3HA) – Retrieves status information about SUNW.HAStoragePlus resources that are used by a resource. This information is obtained from the state (online or otherwise) of all SUNW.HAStoragePlus resources on which the resource depends by using the Resource_dependencies or Resource_dependencies_weak system properties that are defined for the resource. See the SUNW.HAStoragePlus(5) man page for more information.
The following functions fail over or restart a resource or resource group:
scds_failover_rg(3HA) – Fails over a resource group.
scds_restart_rg(3HA) – Restarts a resource group.
scds_restart_resource(3HA) – Restarts a resource.
The following functions execute a command under a timeout and convert an error code to an error message:
scds_timerun(3HA) – Executes a command under a timeout value.
scds_error_string(3HA) and scds_error_string_i18n(3HA) – Translates an error code to an error string. Strings that are returned by scds_error_string() are displayed in English. Strings that are returned by scds_error_string_i18n() are displayed in the native language that is specified by the LC_MESSAGES locale category.
scds_svc_wait(3HA) - Waits for the specified timeout period for a monitored process to die.
