You can delete EJB
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, select
Deployments.
In the right
pane, expand the application that contains the EJB component for which
you want to delete credential mappings; to expand an application,
click + next to the application name.
Within the
expanded application, locate and click the name of the EJB component
for which you want to delete credential mappings.
Click 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).
