  • logical停止 apply解决一例

    今年五一因更换存储柜,更换服务器,DB重作,logical standby也重做了。三号检查状况,如下:

    SQL> SELECT SESSION_ID, STATE FROM V$LOGSTDBY_STATE;

    SESSION_ID STATE

    ---------- ----------------------------------------------------------------

             1 APPLYING

    SQL>SELECT NEWEST_SCN-APPLIED_SCN scn FROM DBA_LOGSTDBY_PROGRESS;

    发现大量SQL没有Apply

    等了很久,发现没有apply的越来越多。查看log,发现如下log.

    以上是physical时数据库的log,在变为logical后的log如下。发现之前已经recover的某些loglogical又重新apply

    数据库apply1133后停了。1134—1137已经end mining.检查状态,仍然在applying.可是数据库的确没有动作,百思不得其解。

    发现如下log.没有办法的时候,决定试一下再手工注册一下D:\mes\archive\ARC001_071784095401138.arc这个log,发现数据库开始apply.再手工注册剩余未注册的log,数据库正常工作。

    SQL>select sid,type,status_code,status from v$logstdby_process;

    SID      TYPE   STATUS_CODE          STATUS

    2730    COORDINATOR        16116 ORA-16116: no work available

    2728    READER         16240 ORA-16240: Waiting for logfile (thread# 1sequence# 1138)

    2726    BUILDER        16116 ORA-16116: no work available

    2727    PREPARER     16116 ORA-16116: no work available

    2721    ANALYZER    16117 ORA-16117: processing

    2725    APPLIER         16116 ORA-16116: no work available

    2724    APPLIER         16116 ORA-16116: no work available

    2723    APPLIER         16116 ORA-16116: no work available

    手工注册log的语句如下:

    ALTER DATABASE   REGISTER logfile 'D:\MES\ARCHIVE\ARC001_071784095401138.ARC';
