Construct a JDBC URL | Generated by AI

Home PDF

To construct a JDBC URL for connecting to a DB2 database based on the properties.db2.jcc element in the server.xml file of a WebSphere Liberty Profile, you need to use the values provided for certain key attributes, such as databaseName, serverName, and portNumber. Here’s how to do it:

Basic JDBC URL Format for DB2

The standard format for a JDBC URL using the DB2 JDBC Type 4 driver (which is commonly used in Liberty Profile setups) is:

jdbc:db2://<serverName>:<portNumber>/<databaseName>

Steps to Construct the URL

  1. Identify the Required Properties: From the properties.db2.jcc element in server.xml, extract the values for serverName, portNumber, and databaseName. These are the essential components needed for the URL.
  2. Assemble the URL: Combine these values into the format above, ensuring proper separators (: between server and port, / before the database name).
  3. Handle Additional Properties (if present): If properties.db2.jcc includes other attributes (e.g., currentSchema, sslConnection), they can sometimes be appended to the URL, but this depends on their nature. Typically, properties like user and password are passed separately when establishing the connection, not in the URL, for security reasons.

Example

Suppose your server.xml contains the following properties.db2.jcc configuration:

<properties.db2.jcc databaseName="SAMPLE" serverName="localhost" portNumber="50000" user="dbuser" password="dbpass"/>

The JDBC URL would be:

jdbc:db2://localhost:50000/SAMPLE

Including Additional Properties (Optional)

If additional properties are specified in properties.db2.jcc, such as currentSchema or sslConnection, and you want to include them in the URL (though some may be better set in connection properties), append them after the database name with a colon (:) followed by semicolon-separated property=value pairs. For instance:

<properties.db2.jcc databaseName="SAMPLE" serverName="localhost" portNumber="50000" currentSchema="MYSCHEMA" sslConnection="true"/>

The URL could become:

jdbc:db2://localhost:50000/SAMPLE:currentSchema=MYSCHEMA;sslConnection=true;

However:

Final Answer

In the context of your query, assuming properties.db2.jcc provides at least databaseName, serverName, and portNumber, the JDBC URL is constructed as:

jdbc:db2://<serverName>:<portNumber>/<databaseName>

Replace <serverName>, <portNumber>, and <databaseName> with the actual values from your properties.db2.jcc configuration. If additional properties are present and intended for the URL, append them as :property1=value1;property2=value2;, but typically, properties like user, password, and sslConnection are handled separately in the connection setup.
