Database connection problems
A faulty JDBC driver or data source can prevent you from accessing a Lotus Connection feature. Here's how to test the connections and correct problems. If you encounter a HTTP 500 - Internal Server Error when attempting to access a Lotus Connections feature for the first time, make sure that you are using the Web address. If the Web address is correct, test the validity of your database connection, by performing the following steps from the WAS admin console:
- Verify the database connections by selecting Resources > JDBC > JDBC Providers > feature_nameJDBC > Data Source.
- Select a Lotus Connections data source, and then click Test Connection.
- If the connections fails, use one of the following approaches to locate and resolve the problem:
- Data source problems – Select the data source and review the database server values to ensure they are correct. Check the port number, server name, and database name. If you discover an error, change the value, click OK and Save, and then retest the database connection.
- JDBC driver path problems – Check to ensure the path assigned to a feature's JDBC driver is correct. Select Environment > WebSphereVariables, and then review the path for the JDBC driver variable to make sure it is correct. The driver path is named using the syntax: <FEATURE>_JDBC_DRIVER_HOME. Note that on Linux this path is case-sensitive. If the path is incorrect, change it, and then click OK and Save.
- JAAS credential problems – Check the JAAS J2C authentication settings by selecting Resources > JDBC > JDBC Providers > <Feature_name>JDBC > datasource > <Feature_name> > JAAS-J2C authentication data. Select <Feature_name>JAASAauth, and then view the user ID and password credentials you entered during installation to verify that they are correct. If they are not correct, make any required changes.
