Implementation of the ‘OracleDBChannelInfo’ model.

Note: The name of this proto message is out-dated. This proto can represent more than just the database channel information. It should be renamed in the future.

Attributes:

archivelog_keep_days (int): Archived log deletion policy for this

unique Oracle database. 1: keep archived log forever 0: delete archived log immediately n>0: delete archived log after n days

db_unique_name (string): The unique name of the database. db_uuid (string): Database id, internal field, is filled by magneto

master based on corresponding app entity id.

enable_dg_primary_backup (bool): If set to false, and if the DG database

role is primary, we will not allow the backup of that database.

host_info_vec (list of OracleDBChannelInfoHostInfo): Vector of Oracle

hosts from which we are allowed to take the backup/restore. In case of RAC database it may be more than one.

max_num_host (int): Maximum number of hosts from which we are allowed

to take backup/restore parallely. This will be less than or equal to host_info_vec_size. If this is less than host_info_vec_size we will choose max_num_host from host_info_vec and take backup/restore from this number of host.

num_channels (int): The default number of channels to use per host per

db. This value is used on all hosts unless host_info_vec.num_channels is specified for that host. Default value for num_channels will be calculated as minimum number of nodes in cohesity cluster, and 2 * number of cpu on Oracle host. Preference order for number of channels per host for given db is: 1. If user has specified host_info_vec.num_channels for host we will use that. 2. If user has not specified host_info_vec.num_channels but specified num_channels we will use this. 3. If user has neither specified host_info_vec.num_channels nor num_channels we will calculate default channels with above formula.

rman_backup_type (int): Type of Oracle RMAN backup rquested (i.e

ImageCopy, BackupSets).

classmethod from_dictionary(dictionary)

Creates an instance of this model from a dictionary

Args:

dictionary (dictionary): A dictionary representation of the object as obtained from the deserialization of the server’s response. The keys MUST match property names in the API description.

Returns:

object: An instance of this structure class.
