This task creates and deletes Java™ 2
Connector (J2C) authentication data entries.
Before you begin
Java Platform, Enterprise Edition
(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 by 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 Java Authentication
and Authorization Service, 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 Java Authentication
and Authorization Service, 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).
Important: 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
.
This
full alias name is the one used in your deployment descriptor.
- Click OK or Apply.
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 deployment manager.
After you restart the deployment manager, the J2C authentication data
is reflected in the runtime configuration. Any changes to the J2C
authentication data fields require a deployment manager 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.
