    V$DATAGUARD_STATUS - Log Transport Services Warning

    oraman
      Hello gurus,

      OS read hat, oracle enterprise edition 11g release 2, dataguard 2 physical standby's

      everything works fine but since 1 day we get following warnings from dataguard on the primary server:

      SELECT * FROM V$DATAGUARD_STATUS;

      FACILITY          SEVERITY     DEST_ID MESSAGE_NUM ERROR_CODE CAL TIMESTAM
      ------------------------ ------------- ---------- ----------- ---------- --- --------
      MESSAGE
      ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
      Log Transport Services     Warning          0 309911     0 NO 01.11.12
      RTC returned 2, disabling RTC for next 2 I/Os.

      does anybody know this warning message?

      in the alert log it looks like this:

      RTC returned 2, disabling RTC for next 2 I/Os.
