JDBC type data source A JDBC data source retrieves its data via a JDBC driver, usually type 4 network. The JDBC connection is available either directly from the ServiceNow instance (a VPN setup required), or via a dedicated MID Server installed inside your firewall that can access the database port. Note: JDBC calls from the MID Server are never encrypted. Limit the rights available to the MID Server user whenever making JDBC calls from a MID server. JDBC data source supported database formats JDBC data sources support several database formats and ports. Table 1. Supported database formats SQL Server Type Port MySQL 3306 Microsoft SQL Server 1433 Oracle 1521 Note: Oracle DATE fields are loaded as ServiceNow datetime fields. JDBC data source SQL statement requirements JDBC queries that run SQL statements must specify a column name. For example, this query specifies the column name ServerID.SELECT DISTINCT 'server_name:' + CONVERT ( VARCHAR , lg .ResourceID ) AS 'ServerID' ,LastHWScan ,Account0 ,Category0 Fromv_GS_WORKSTATION_STATUSsInner JOIN v_GS_LocalGroupMembers0lg ON s .ResourceID = lg .ResourceID WhereType0 = 'Local' AND Category0 = 'SystemAccount' SQL server integrated authentication for Windows A JDBC data source can use the ID of for the Windows MID Server service user to authenticate with SQL Server. The Use integrated authentication check box on the Data Source form determines if the JDBC data source uses the MID Server service user credentials. For this field to appear on the Data Source form, the integration must meet these criteria: The MID Server must be running on a Windows computer with SQL Server. The MID Server service must use the same credentials that SQL Server requires. The data source Type is JDBC. The data source Use MID Server check box is selected. The data source Format is SQLServer. Important: If integrated authentication is chosen, and you are integrating with Microsoft System Center Configuration Manager, the account running the MID Server service must have read rights on the SCCM database. Figure 1. Data Source form Adding JDBC drivers for unsupported database formats Use the following procedure to extend the data source to use a driver for a database that is not provided in the base system. JDBC connections are supported for the following default databases: Add a new JDBC format choice Extend the available JDBC driver options by creating a new choice list entry to specify the JDBC driver Java package name. Before you begin Role required: import_admin About this task Add a new choice list entry for the new database to the Format field in the sys_data_source table. Procedure Navigate to System Import Sets > Administration > Data Sources. Click New. In the Data Sources form, right-click the Format field label, and select Show Choice List from the pop-up menu. Click New in the list of choices. Provide the following values to create the new database choice. Look at the existing drivers for examples. Table: sys_data_source Label: Database name that appears as an option in the Format choice list, for example: Teradata. Value: Package name and class of the driver. For example, the value for TeraData is com.ncr.teradata.TeraDriver.Note: The driver package and class must be provided by the driver vendor. This information is often available in the vendor's documentation, such as for MariaDB or Teradata. Dependent value: JDBC Click Submit. The new data source now appears in the list of available JDBC formats. Add Sybase or DB2 JDBC format choices Extend the available JDBC driver options by activating the Sybase or DB2 choices. Before you begin Roles required: admin Important: To use Sybase or DB2 JDBC drivers, you must manually install the driver JAR file on a MID server. Refer to KB0551236 for more information. About this taskActivate the Sybase or DB2 JDBC drivers to connect with those database formats through a MID server. This procedure assumes you are using the following Sybase or DB2 drivers:Table 2. Drivers Format Driver Driver class Sybase jconnect-jdbc com.sybase.jdbc3.jdbc.SybDriver DB2 db2jcc com.ibm.db2.jcc.DB2Driver If you are using a different implementation of the Sybase or DB2 driver, you must modify the choice Value to use the driver class from your driver implementation. Procedure Navigate to System Import Sets > Administration > Data Sources. Click New. In the Type field, select JDBC. Right-click the Format field label, and select Configure Choices from the pop-up menu. Move the Sybase or DB2 Universal choices from the Available column to the Selected column. Click Save. The new data source now appears in the list of available JDBC formats. Install a driver on a MID Server You can install a new JDBC driver JAR file to a MID server to access database formats that are not supported by default. Before you begin Role required: agent_admin Procedure Navigate to MID Server > JAR Files. Click New. Complete the following fields: Name: A unique and descriptive name for identifying the file in the instance. Version: A version number for the file, if one is available. Source: Location of the JAR file for reference purposes. Source information is not used by the system. Description: Short description of the JAR file and its purpose in the instance. Click the paper clip icon in the banner and attach the JAR file to the record. Click Submit. Restart the MID Server service. The platform makes the JAR file available to any MID Server configured to communicate with the instance. Create a new JDBC data source for an unsupported database format Add a new JDBC data source by defining a data source record. Before you begin Role required: import_admin Procedure Navigate to System Import Sets > Administration > Data Sources and click New. In the Data Source form, select JDBC from the list in the Type field. Select the new data source from the choice list in the Format field. Configure the form and add the Connection URL field. Provide the connection URL to the JDBC data source, and then click Submit. No other connection information is required.
