Adding

Groups (sometimes referred as Permissions), determines the feature

and privileges of the user. A privilege may be the ability to create

Account users, or the amount of Memory RAM allocated to the

JVM (Runtime) running the application server for the user.

The Application Server available to a group must have enough RAM

memory. The following is the minimum RAM Memory required for the

associated application server:

Jetty: 64MB

Tomcat: 64MB

JBoss 4.x: 128MB

Glassfish 2.x: 128MB

JBoss 5.x: 256MB

JBoss 6.x: 256MB

Glassfish 3.x: 256MB

Oracle-OC4J: 128MB

A Summary of the Group Attributes is displayed below the selected

group in the NGASI AppServer Manager.

2 types of Groups.

1) - Admin Group

are groups with privileges to manage other User

Accounts (and User Groups).

Some attributes of an Admin Group is:

webhosting - The maximum Web Accounts the Admin belonging to the

group can create or manage.

The default Admin Group that is created at the first time

NGASI AppServer Manager is started is called

"webhostingsample".

The following are the Group Attributes:

owner - admin

webhosting - 1

maxMemory - 250000000

java_ee - Tomcat,JBoss,Jetty,Glassfish,Oracle-OC4J

2) - User Group - End users belong to User Groups. Privileges in

User Groups include the ability to install and run an Application Server.

Some attributes of a User Group:

maxMemory - the Maximum Memory allocated to the Java Application Server

The default User Group that is created at the first time

NGASI AppServer Manager is started is called

"default".

The following are the Group Attributes:

owner - admin

maxMemory - 250000000

java_ee - Tomcat,JBoss,Jetty,Glassfish,Oracle-OC4J

As you can see the main difference between a User Group and an

Admin Group is that there is no value for "webhosting" in a User Group.

While in Admin Group, the value is 1 or greater.

NOTE: Please refer to the "Automation" topic in the Advanced section

to see how to automate Account and Group Management from a script.

NOTE: You can manage Groups directly from the Control Panel by

clicking on any of the "Groups" link located in various places in the

Admin Control Panel. For Groups with less than 50MB RAM, please edit the

value for min_memory in the following file:

/usr/ngasi/webapps/ROOT/WEB-INF/ws/webapps/appservermgr/ZP-INF/wsportal.properties
