setRdbcX stored procedure in Watson Query

setRdbcX stored procedure (Variation 2)

Defines a new data source connection on one or more endpoint nodes. This variation is intended for use with discrete parameters. The schema is DVSYS.

Input parameters

src_type

The type of this required parameter is VARCHAR(20). Specifies the data source type.

host_name

The type of this required parameter is VARCHAR(2000). Specifies the data source hostname.

db_port

The type of this required parameter is INTEGER. Specifies the network port of the data source service.

database_name

The type of this optional parameter is VARCHAR(128). Specifies the name of the database for the connection.

connection_options

The type of this optional parameter is VARCHAR(2000). Specifies a comma-delimited list of extra options in the following format:

'<key1>=<value1>, <key2>=<value2>,
...'

user

The type of this required parameter is VARCHAR(128). Specifies a database username .

password

The type of this unencrypted required parameter is VARCHAR(128). Specifies a database user password.

use_SSL

The type of this required parameter is INTEGER. Specifies whether the database connection uses SSL. Valid values are 0 (the connection does not use SSL) and 1 (the connection uses SSL).

validate_cert

The type of this required parameter is INTEGER. Specifies whether the endpoint validates the database server SSL certificate. Valid values are 0 (no validation) and 1 (validation is required).

cert_host_name

The type of this optional parameter is VARCHAR(2000). Specifies the name of the host that is associated with the SSL certificate. Specifying an empty string or the null value prevents hostname validation.

SSL_certificate

The type of this optional parameter is VARCHAR(32672). Specifies a database server certificate, if required.

node_name

The type of this required parameter is VARCHAR(32672). Specifies the names of the nodes on which the data source is defined.

Run the following query to find valid values for node_name.

SELECT * FROM DVSYS.LISTNODES;

additional_options

The type of this optional parameter is VARCHAR(32672). Specifies a comma-delimited list of extra parameters in the following format:

'<key1>=<value1>, <key2>=<value2>,
...'

. Supported options include EDITCID, DRIVERID, and JWTTOKEN. If you specify EDITCID, existing connection information is replaced with the new information that you provide. For example:

call DVSYS.setRdbcX('old_dsDriver', 'old_dsUrl', 'old_usr', 'newP@ssw0rd', '', '', '', 'NodeIdForMyDB2', 'EDITCID=MYSQL11941', ?, ?, ?)

DRIVERID (the ID of the driver that is to be downloaded) and JWTTOKEN (the Java web token) are used together when these parameters are set. The connector/endpoint downloads the driver from the server.

Access restrictions: Use this option to enable access restrictions Watson Query. Add the restrictions in the form of a nested comma-separated list of tuples specifying the type of access grantee (user, group, or role), and their names. For example:

ACCESS_RESTRICTION={U username, G groupname, R rolename}

Do not use quotation marks to wrap the names. For example, use ACCESS_RESTRICTION={G ALL USERS} instead of ACCESS_RESTRICTION={G "ALL USERS"}.

Output parameters

connection_ID: The type of this parameter is VARCHAR(20). Represents the generated connection ID for Watson Query.
number_of_defined_connections: The type of this parameter is INTEGER. Represents the total number of added connections.
diagnostics: The type of this parameter is VARCHAR(32672). Represents diagnostic output if a failure occurs.

Example

call DVSYS.setRdbcX('DB2','9.30.167.128','50000','TPCDS','','<user>','<password>','0','0','','','qpendpoint_1:6415','',?,?,?);

If you want to edit a data source with a new password, you can use the additional_options parameter with EDITCID.

call DVSYS.setRdbcX('DB2','9.30.167.128','50000','TPCDS','','<user>','<password>','0','0','','','qpendpoint_1:6415','EDITCID=DB2002',?,?,?);
