SYSADMIN_VDB Procedures

The procedures described on this page enable you to manage virtual databases and SSH tunnels.

SYSADMIN_VDB.createVdb

This procedure creates a virtual database:

SQL

SYSADMIN_VDB.createVdb("name" => 'string_name');;

Example

SQL

CALL "SYSADMIN_VDB.createVdb"("name" => 'newVDB');;

SYSADMIN_VDB.dropVdb

This procedure removes a virtual database by ID:

SQL

SYSADMIN_VDB.dropVdb("id" => biginteger_id);;

To view the ID of the virtual database you need to delete, you can use the SYSADMIN_VDB.VirtualDatabases table.

Please be aware that this operation cannot be undone, and a dropped virtual database is gone for good.

Example

SQL

CALL "SYSADMIN_VDB.dropVdb"("id" => 10);;

SYSADMIN_VDB.generateCloudAgentApiKey

This procedure generates a new CLOUD_AGENT_CLIENT_API_KEY option value.

SQL

SYSADMIN_VDB.generateCloudAgentApiKey(OUT newApiKey string RESULT)

Example

SQL

CALL "SYSADMIN_VDB.generateCloudAgentApiKey"() ;;

SYSADMIN_VDB.getCloudAgentConfiguration

The procedure retrieves the contents of all configuration files from all connected agent instances.

SQL

SYSADMIN_VDB.getCloudAgentConfiguration(OUT clientId string NOT NULL, OUT file string NOT NULL, OUT configuration string)

clientId here is a randomly generated UUID assigned to an agent instance upon startup, provided one does not already exist. It is stored in the client_id file within the agent's configuration directory. The clientId serves as a unique identifier for an instance, enabling it to be differentiated from other instances, particularly in environments where multiple agents are deployed in a cluster.

Example

SQL

SELECT * FROM SYSADMIN_VDB.getCloudAgentConfiguration() ;;

SYSADMIN_VDB.getCloudAgentConnectionStatus

This procedure is designed to assess the connection status of a cloud agent for a specific data source or the server in general if NULL is passed as a datasource value.

SQL

SYSADMIN_VDB.getCloudAgentConnectionStatus(IN datasource string, OUT connected boolean NOT NULL)

Parameter name	Parameter type	Mandatory	Description
datasource	string	`NULL`	This parameter specifies the data source for which the connection status needs to be checked.

Examples

SQL

SELECT * FROM "SYSADMIN_VDB.getCloudAgentConnectionStatus"() ;; 

SELECT * FROM "SYSADMIN_VDB.getCloudAgentConnectionStatus"(
    "datasource" => 'some_datasource'
) ;;

SYSADMIN_VDB.getJavaProp

This procedure gets the translator-related client secret:

SQL

SYSADMIN_VDB.getJavaProp(IN key1 string NOT NULL, OUT value1 string RESULT)

Example

SQL

CALL "SYSADMIN_VDB.getJavaProp"("key1" => 'user.language');;

SYSADMIN_VDB.setJavaProp

This procedure sets the translator-related client secret:

SQL

SYSADMIN_VDB.setJavaProp(IN key1 string NOT NULL, IN value1 string)

Example

SQL

CALL "SYSADMIN_VDB.setJavaProp"("key1" => 'user.language', "value1" => 'en');;

SYSADMIN_VDB.updateCloudAgentConfiguration

This procedure creates or updates the configuration in the specified file across all connected agent instances.

`file`	string	`NOT NULL`	The name of the cloud agent properties file to be created, updated, or deleted across all agents
`configuration`	string	`NULL`	Specifies the agent configuration to be written to the designated properties file. If the argument is set to `NULL` or omitted, the properties file will be deleted

Examples

SQL

--Update the configuration stored in "agent_A.properties" file of some cloud agent.
CALL SYSADMIN_VDB.updateCloudAgentConfiguration (
    file => 'agent_A.properties',
    configuration => 'dvsaas.ws.url=ws://localhost:8080/cloud-agent
