Runtime Control

EJB Service provides the runtime management of deployed EJBs. The “Runtime Control” tab provides statistics about the number of active and passive instances of EJBs and their number in the container. In the “Enterprise JavaBeans” box, there is a list of all EJBs deployed on the EJB Container of SAP J2EE Engine 6.20. There are several options to manipulate them:

Properties –displays properties of a selected EJB. They can be changed to change the bean. These changes take effect only if the “Set” option is used at the end. Enterprise JavaBeans properties are also displayed by choosing (Properties) on the toolbar.
Set – sets the changes to an EJB made when the “Properties” option was used. Changes can also be set by choosing (Set) on the toolbar.
Set all – similar to “Set” option. Used to set changes made to several EJBs simultaneously. All changes can also be set by choosing (Set all) on the toolbar.
Restore – restores EJB properties from the last-used “Set” option. This can also be performed by choosing (Restore) on the toolbar.
