You can delete EJB 2.X
component credential mappings that are no longer needed.
If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
In the left pane of the Console, select
Deployments.
In the
Deployments table, expand the application that
contains the EJB component for which you want to delete credential
mappings.
Select the
name of the EJB component for which you want to delete credential
mappings.
Select Security > Credential
Mappings.
In the EJB Component Credential Mappings
table, check (select) to box next to the name of the credential
mapping you want to delete.
Click Delete.
Click
Yes to confirm your decision.
To activate these changes, in the Change Center of the Administration Console, click Activate Changes. Not all changes take effect immediately—some require a restart (see Use the Change Center).
