Constructor Detail

AlterResourceGroupRequest

public AlterResourceGroupRequest()

Constructs an AlterResourceGroupRequest object with default parameters.

AlterResourceGroupRequest

public AlterResourceGroupRequest(String name,
                                 Map<String,Map<String,String>> tierAttributes,
                                 String ranking,
                                 String adjoiningResourceGroup,
                                 Map<String,String> options)

Constructs an AlterResourceGroupRequest object with the specified parameters.

Parameters:

name - Name of the group to be altered. Must be an existing resource group name or an empty string when used inconjunction with the is_default_group option.

tierAttributes - Optional map containing tier names and their respective attribute group limits. The only valid attribute limit that can be set is max_memory (in bytes) for the VRAM & RAM tiers. For instance, to set max VRAM capacity to 1GB and max RAM capacity to 10GB, use: {'VRAM':{'max_memory':'1000000000'}, 'RAM':{'max_memory':'10000000000'}}

• MAX_MEMORY: Maximum amount of memory usable in the given tier at one time for this group.

The default value is an empty Map.

ranking - If the resource group ranking is to be updated, this indicates the relative ranking among existing resource groups where this resource group will be moved; leave blank if not changing the ranking. When using before or after, specify which resource group this one will be inserted before or after in adjoiningResourceGroup. Supported values:

• EMPTY_STRING
• FIRST
• LAST
• BEFORE
• AFTER

The default value is EMPTY_STRING.

adjoiningResourceGroup - If ranking is before or after, this field indicates the resource group before or after which the current group will be placed; otherwise, leave blank. The default value is ''.

options - Optional parameters.

• MAX_CPU_CONCURRENCY: Maximum number of simultaneous threads that will be used to execute a request for this group.
• MAX_DATA: Maximum amount of cumulative ram usage regardless of tier status for this group.
• MAX_SCHEDULING_PRIORITY: Maximum priority of a scheduled task for this group.
• MAX_TIER_PRIORITY: Maximum priority of a tiered object for this group.
• IS_DEFAULT_GROUP: If true, this request applies to the global default resource group. It is an error for this field to be true when the name field is also populated. Supported values:
  • TRUE
  • FALSE
  The default value is FALSE.
• PERSIST: If true and a system-level change was requested, the system configuration will be written to disk upon successful application of this request. This will commit the changes from this request and any additional in-memory modifications. Supported values:
  • TRUE
  • FALSE
  The default value is TRUE.

The default value is an empty Map.
