Using the User Transaction Management MBean, a client can demarcate transaction boundaries for a subset of profile-management operations, by:

  • starting a user transaction

  • performing some profile-management operations, across a number of different profiles (in the context of that transaction)

  • then committing the transaction — resulting in an atomic update of profile state.

Binding user transactions with authenticated subjects

The SLEE binds user transactions to the java.security.auth.Subject associated with the invoking thread. For all user-transaction management, the thread invoking the management operation must therefore be associated with an authenticated subject. The command console interface handles this task as part of the client-login process. (Other user-provided m-lets installed in the Rhino SLEE will need to take care of this requirement in their own way.)

Executing Profile Provisioning operations in a user transaction

The following operations on the Profile Provisioning MBean support execution in a user transaction: createProfile, createProfiles, removeProfile, getDefaultProfile, getProfile, and importProfiles

Furthermore, accessing a Profile MBean while a user transaction is active:

  • enlists that MBean into that user transaction

  • changes that MBean to the read/write state

  • puts any changes to the profile in context of the user transaction.

Note
Committing or rolling back profiles enlisted in user transactions

You cannot invoke the ProfileMBean.commitProfile() or ProfileMBean.restoreProfile() operations on a Profile MBean enlisted in a user transaction. Any changes made to such a profile will be committed or rolled back when the user transaction is committed or rolled back (respectively).
