HADR使用的端口不能为 SVCENAME or SVCENAME +1

Comm time-out in unforced HADR primary start, to avoid split-brain

发现两边的设置HOST不能使用ALIAS，端口最好不要使用字母

          because the HADR configuration parameters do not match. Change the
          configuration parameters HADR_TIMEOUT and HADR_SYNCMODE on either the
          HADR primary or standby so that they match the other system's values,
          and ensure that HADR_LOCAL_HOST and HADR_REMOTE_HOST match the host
          name of the local and remote machines.

检查两边的设置，发现HADR_SYNCMODE 不一致导致
