db_create
Creates a new database. A database with this name or UUID must not already exist.
Mandatory Parameters
Parameter Name | Data Type | Description |
---|---|---|
db_name | string | Unique name of the new database |
version | string | Version of the database, i.e. "8.0.0" |
data_volume_name | string | Volume name for the database data. The volume must be created beforehand. This parameter may be substituted by data_volume_id. |
mem_size | string | Amount of memory (RAM) allocated to the database in MiB, GiB, or TiB, i.e. "2048 MiB" |
nodes | list | List of active and reserved node IDs for this database. The node IDs are integers. |
num_active_nodes | integer | Number of active nodes in the database |
Optional Parameters
Parameter Name | Data Type | Description |
---|---|---|
db_uuid | string | UUID for the database cluster in base64 format. Name is used as fallback if it is a valid UUID. |
data_volume_id | integer | Volume ID for the database data. data_volume_id can substitute data_volume_name. If both data_volume_id and data_volume_name are specified, data_volume_id is used instead. |
port | integer | Port that the database is reachable on. If no port is specified, the database is created with port 8563 |
owner | tuple, list | Tuple of (User id, group id) of the database owner in type integer or (user name, user group name). If no owner is specified, the owner is the user who executed the db_create job. |
params | string | A space-seperated list of extra database parameters that are set when the database is created. In general, parameters are in the format "-param=value", e.g. "-param1=1 -param2=0" |
enable_auditing | boolean | Enables or disables auditing for the database. The default value is True. |
ldap_server | string | Comma-separated list of LDAP Servers to use for remote database authentication, e.g. "ldap[s]://192.168.16.10". Each server must start with "ldap://" or "ldaps://". |
cloud_data_volume_name | string | The name of the cloud-based storage volume to use (e.g. "DataVolume3"). The volume must be created beforehand. |
snapshot_sync_volume | string | The name of the cloud-based snapshot sync volume to use (e.g. "SnapshotSyncVolume1"). The volume must be created beforehand. |
cache_volume_disk | string | Specify disks to use for cache in the format <diskname>:<volumesize>, e.g. "disk1:7 GiB". |
interfaces | string | Comma-seperated list of network interfaces to use for the database. Leave empty to use all possible network interfaces. The default value is "". |
volume_quota | integer | Maximum size of the data volume in GiB. If the quota is reached, the database tries to shrink the volume on start-up if required and possible. |
volume_move_delay | integer | Specifies the delay in seconds after which the volume on a failed node is moved to the reserve node automatically. When no value is set, there is no delay. |
master_database | string | The name of the master database if a worker database is being created. |
auto_start | boolean | Specifies if the database starts on cluster boot automatically. The default value is True. |
default_sys_passwd_hash | string | The hash used to set the default SYS password during database creation. |
additional_sys_passwd_hashes | string | A semi-colon seperated list of password hashes that allow authentication as SYS independent of the SYS password set. |
builtin_script_language_name | string | Name of the script language container to use per default without a file name extension. |
jdbc_urls | tuple, list | List of URLs used to search for JDBC drivers, like: bucketfs://bfs2/bucket3/jdbcdir or file:///exa/etc/jdbc_drivers. |
oracle_url | string | An URL used to search for oracle instant client, like: bucketfs://bfs2/bucket3/oracle_dir. |
initial_sql | string | Absolute path to a YAML file with SQL statements to run during the first database startup. |
