Manage Java 2 Connector Architecture authentication data entries for JAAS
This task creates and deletes Java 2 Connector (J2C) authentication data entries. Java EE Connector authentication data entries are used by resource adapters and Java DataBase Connectivity (JDBC) data sources. A Java EE Connector authentication data entry contains authentication data, which includes the following information:
Alias
An identifier that identifies the authentication data entry. When configuring resource adapters or data sources, the administrator can specify which authentication data to choose using the corresponding alias.
User ID
A user identity of the intended security domain. For example, if a particular authentication data entry is used to open a new connection to DB2, this entry contains a DB2 user identity.
Password
The password of the user identity is encoded in the configuration repository.
Description
A short text description.
Procedure
- Delete a J2C authentication data entry.
- Click Security > Global security.
- Under JAAS, click J2C authentication data. The J2C Authentication Data Entries panel is displayed.
- Select the check boxes for the entries to delete and click Delete. Before deleting or removing an authentication data entry, make sure that it is not used or referenced by any resource adapter or data source. If the deleted authentication data entry is used or referenced by a resource, the application that uses the resource adapter or the data source fails to connect to the resources.
- Create a new J2C authentication data entry.
- Click Security > Global security.
- Under JAAS, click J2C authentication data. The J2C Authentication Data Entries panel is displayed.
- Click New.
- Enter a unique alias, a valid user ID, a valid password, and a short description (optional).
When creating a new authentication data entry and specifying an alias, be aware that the node name is automatically appended as a prefix to the alias name you specify. For example, if you specify the alias, tek_test_Con3, and the node is MyNode, then the final alias name is: MyNode/tek_test_Con3.
Remember that this full alias name is the one used in your deployment descriptor.
- Click OK. No validation for the user ID and password is required.
- Click Save.
Make sure that a file synchronized operation is performed to propagate the changes to other nodes.
Results
A new J2C authentication data entry is created or an old entry is removed. The newly created entry is visible without restarting the application server process to use in the data source definition. But the entry is only in effect after the server is restarted. Specifically, the authentication data is loaded by an application server when starting an application and is shared among applications in the same application server.If you create or update a data source that points to a newly created J2C authentication data alias, the test connection fails to connect until you restart the dmgr. After you restart the dmgr, the J2C authentication data is reflected in the run-time configuration. Any changes to the J2C authentication data fields require a dmgr restart for the changes to take effect. The node agent must also be restarted.
What to do next
This step defines authentication data that you can share among resource adapters and data sources. Use the authentication data entry that is defined in the resource adapters or the data sources.
