For Microsoft SQL Server initialization, Replication Agent for Microsoft SQL Server installs objects at both the data server and database level. The data server-level modifications are only required once. However, to make the server-level modifications, additional permission are required, the pds_dac_port_number parameter is used, and the primary database must be in standalone mode. Subsequent executions of pdb_xlog init do not modify the server again and do not require the additional permission or configurations.
