Access Jira Service Management Data as a Remote Oracle Database

The Oracle Database Gateway for ODBC and Heterogeneous Services technology enable you to connect to ODBC data sources as remote Oracle databases. This article shows how to use the CData ODBC Driver for Jira Service Management to create a database link from Jira Service Management to Oracle and to query Jira Service Management data through the SQL*Plus tool. You can also create the database link and execute queries from SQL Developer.

Connect to Jira Service Management as an ODBC Data Source

Information for connecting to Jira Service Management follows, along with different instructions for configuring a DSN in Windows and Linux environments.

You can establish a connection to any Jira Service Desk Cloud account or Server instance.

Connecting with a Cloud Account

To connect to a Cloud account, you'll first need to retrieve an APIToken. To generate one, log in to your Atlassian account and navigate to API tokens > Create API token. The generated token will be displayed.

Supply the following to connect to data:

• User: Set this to the username of the authenticating user.
• APIToken: Set this to the API token found previously.

Connecting with a Service Account

To authenticate with a service account, you will need to supply the following connection properties:

• User: Set this to the username of the authenticating user.
• Password: Set this to the password of the authenticating user.
• URL: Set this to the URL associated with your JIRA Service Desk endpoint. For example, https://yoursitename.atlassian.net.

Note: Password has been deprecated for connecting to a Cloud Account and is now used only to connect to a Server Instance.

Accessing Custom Fields

By default, the connector only surfaces system fields. To access the custom fields for Issues, set IncludeCustomFields.

Windows

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Note: If you need to modify the DSN or create other Jira Service Management DSNs, you must use a system DSN and the bitness of the DSN must match your Oracle system. You can access and create 32-bit DSNs on a 64-bit system by opening the 32-bit ODBC Data Source Administrator from C:\Windows\SysWOW64\odbcad32.exe.

Linux

If you are installing the CData ODBC Driver for Jira Service Management in a Linux environment, the driver installation predefines a system DSN. You can modify the DSN by editing the system data sources file (/etc/odbc.ini) and defining the required connection properties.

/etc/odbc.ini

For specific information on using these configuration files, please refer to the help documentation (installed and found online).

Set Connection Properties for Compatibility with Oracle

The driver provides several connection properties that streamline accessing Jira Service Management data just as you would an Oracle database. Set the following properties when working with Jira Service Management data in SQL*Plus and SQL Developer. For compatibility with Oracle, you will need to set the following connection properties, in addition to authentication and other required connection properties.

• MapToWVarchar=False

  Set this property to map string data types to SQL_VARCHAR instead of SQL_WVARCHAR. By default, the driver uses SQL_WVARCHAR to accommodate various international character sets. You can use this property to avoid the ORA-28528 Heterogeneous Services data type conversion error when the Unicode type is returned.

• MaximumColumnSize=4000

  Set this property to restrict the maximum column size to 4000 characters.

• IncludeDualTable=True

  Set this property to mock the Oracle DUAL table. SQL Developer uses this table to test the connection.

Linux Configuration

In Linux environments, Oracle uses UTF-8 to communicate with the unixODBC Driver manager, whereas the default driver encoding is UTF-16. To resolve this, open the file /opt/cdata/cdata-driver-for-jiraservicedesk/lib/cdata.odbc.jiraservicedesk.ini in a text editor and set the encoding.

cdata.odbc.jiraservicedesk.ini

Configure the ODBC Gateway, Oracle Net, and Oracle Database

Follow the procedure below to set up an ODBC gateway to Jira Service Management data that enables you to query live Jira Service Management data as an Oracle database.

1. Create the file initmyjiraservicedeskdb.ora in the folder oracle-home-directory/hs/admin and add the following setting:

   initmyjiraservicedeskdb.ora

   HS_FDS_CONNECT_INFO = "CData JiraServiceDesk Sys"
2. Add an entry to the listener.ora file. This file is located in oracle-home-directory/NETWORK/admin.

   If you are using the Database Gateway for ODBC, your listener.ora needs to have a SID_LIST_LISTENER entry that resembles the following:

   listener.ora

   SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = myjiraservicedeskdb) (ORACLE_HOME = your-oracle-home) (PROGRAM = dg4odbc) ) )

   If you are using Heterogeneous Services, your listener.ora needs to have a SID_LIST_LISTENER entry that resembles the following:

   listener.ora

   SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = myjiraservicedeskdb) (ORACLE_HOME = your-oracle-home) (PROGRAM = hsodbc) ) )

3. Add the connect descriptor below in tnsnames.ora, located in oracle-home-directory/NETWORK/admin:

   tnsnames.ora

   myjiraservicedeskdb = (DESCRIPTION= (ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521)) (CONNECT_DATA=(SID=myjiraservicedeskdb)) (HS=OK) )
4. Restart the listener.

5. Test the configuration with the following command:

   tnsping myjiraservicedeskdb

6. Open SQL*Plus and create the database link with the command below:

   CREATE DATABASE LINK myjiraservicedeskdb CONNECT TO "user" IDENTIFIED BY "password" USING 'myjiraservicedeskdb';

You can now execute queries in SQL*Plus like the one below (note the double quotation marks around the table name):
