Start the standalone enqueue server at the command line using this command:

enserver pf=<enserver_profile>

You can then also start up the replication enqueue server:

enrepserver pf=<enrepserver_profile>

Since the replication server connects to the enqueue server, you should only start the replication server once the enqueue server is running.

Later, you can integrate the programs in your SAP system startup sequence.
