1.查看OGG线程状态
GGSCI (klcoredb-node1) 46> info all
Program Status Group Lag at Chkpt Time Since Chkpt

2.查看replicate线程在什么
send REPLICAT REP_1B trace2 /home/oracle/trace2.log

4.查看系统当前运行的sql
多次刷新发现sql
ALTER SEQUENCE "LP_GL_INTERFACE_SEQ" NOCYCLE
5.查看当前sequnce的裱花
SQL> set time on
14:14:27 SQL> SELECT LAST_NUMBER,INCREMENT_BY FROM DBA_SEQUENCES WHERE SEQUENCE_NAME='LP_GL_INTERFACE_SEQ';
LAST_NUMBER INCREMENT_BY

6.缓解同步sequence延时 在replice相关参数文件中添加参数：
DBOPTIONS _NOAUTOMATICSEQUENCEFLUSH
--Metalink 说明
The replicat changes the last_number in target sequence by querying the nextval, but this change is not secured if the target database goes down. The observed DDL will move the high water mark (HWM) of target sequence and make sure sequences replicate reliably for each sequence record.
The DDL may be skipped with replicat parameter:
DBOPTIONS _NOAUTOMATICSEQUENCEFLUSH
However, if target db goes down, the sequence number may be out of sync with source. then you will need to use FLUSH to make sure they are in sync (or FLUSH it before the target goes down, for scheduled shutdown).
