Module administration

A module is a set of binary codes having, in general, the same source code. Each binary code targets a specific (OS, CPU) platform. A module can be “fed” with binary codes either through a client application or by the web interface. Developers can use it as a building block to develop their applications. To create modules and administrate their access rights, you have to be administrator.

Create a module

  • Login as an administrator
  • In the home page, click on the cart at the bottom right and select “Modules” button
  • Click on “Add” button to create a new module and assign it to a user (owner). The module owner can assign binaries to that module.

Assign users to a given module

Fill a module by its binaries

  • Go to “Administration->Modules->Access rights”.
  • Choose “by users” or “by modules”.
  • Here, you can choose which users have which rights in which modules. A user can have :
    • no rights on a module
    • right to run a module (submit jobs belonging to this module)
    • right to run and modify a module (submit jobs and upload executables related to the module)

4. Test the connection pool ./bin/asadmin ping-connection-pool myxwchsqlpool

5. Create a database resource ./bin/asadmin create-jdbc-resource –connectionpoolid=myxwchsqlpool jdbc/xwchdb
