DGMGRL> DGMGRL> [oracle@PD009 ~]$ oerr ora 16698
16698, 0000, "LOG_ARCHIVE_DEST_n parameter set for object to be added"
// *Cause:  One or more LOG_ARCHIVE_DEST_n initialization parameters that
//          contain a SERVICE attribute but not the NOREGISTER attribute were
//          set when attempting to create a configuration or add a standby or
//          far sync instance to the configuration.  askmac.cn
// *Action: If creating a configuration, clear all LOG_ARCHIVE_DEST_n
//          initialization parameters that contain a SERVICE attribute but not
//          the NOREGISTER attribute. If adding a standby database or far sync
//          instance, clear the LOG_ARCHIVE_DEST_n initialization parameter
//          that specifies the database or far sync instance to be added.

这个错误可以通过在Primary 和 Standby上取消log_archive_dest_n参数来解决，实际这一块的参数应当是交给DG broker 来管理了，不再需要人为介入设置。
