Can I enforce unique client naming without creating a transaction log file?

AMPS enforces unique client naming whenever there's a journal (transaction log) configured, and allows duplicate clients when there's no journal configured.

If you'd like to enforce unique client naming, but don't need a journal, there's a simple workaround. You can enable transaction logging without capturing any topics. The configuration file snippet below shows how:

<TransactionLog>

   <JournalDirectory>./journals</JournalDirectory>

</TransactionLog>

 With this snippet, AMPS enables transaction logging for the instance, but does not capture any messages to the log file. This enables the client name uniqueness checks.
