Goldengate简单搭建

SQL> select tablespace_name from dba_tablespaces;

TABLESPACE_NAME

SYSTEM

UNDOTBS1

SYSAUX

TEMP

UNDOTBS2

USERS

GOLDENGATE

7 rows selected.

二

SQL> create user ogg identified by a default tablespace goldengate temporary tablespace temp;

User created.

三

SQL> grant connect to ogg;

Grant succeeded.

SQL> grant alter any table to ogg;

Grant succeeded.

SQL> grant dba to ogg;

Grant succeeded.

SQL>

SQL>

SQL>

SQL>

SQL>

SQL> grant resource to ogg;

Grant succeeded.

四、检查RAC节点间同步

时间不同步，不单单是ogg，集群可能由于时间不一致导致出错，ogg的错误可能是抽取进程中断。

五

SQL> archive log list;

Database log mode Archive Mode

Automatic archival Enabled

Archive destination +DATA/test/archivelog

Oldest online log sequence 54

Next log sequence to archive 55

Current log sequence 55

六

export LD_LIBRARY_PATH=$ORACLE_HOME/lib

七：添加最小附加日志及FORCE_LOGGING

SQL> select SUPPLEMENTAL_LOG_DATA_MIN from v$database;

SUPPLEME

NO

SQL> alter database force logging;

Database altered.

SQL>

SQL> alter database add SUPPLEMENTAL log data;

Database altered.

注：打开补充日志最好在夜里业务很少的时候进行。如果是RAC需要在每个节点上都执行。

完成后建议执行一次归档操作：

alter system archive log current;

开始安装Goldengate

start ext_app

–启动抽取进程（这个暂时不要起，等ogg目标端把数据都恢复的差不多了再起，那样就可以快点）

–如10T数据500G的归档(RMAN)，每天产生100G归档，那么现把10T的数据和500G的归档恢复完，看这段时间产生了多少归档，

–比如总共用了3天，那么还可以接着追300G的归档，在最后一次备份归档的之前记录下SCN号再去备归档，然后再做恢复。

–这样避免exttrail文件产生大量数据，ogg恢复应该也比不上recover（毕竟走网络）

SQL> select CHECKPOINT_CHANGE# ,CURRENT_SCN from v$database;

CHECKPOINT_CHANGE# CURRENT_SCN

1651897 1673978

这里就是ogg数据的初始化。

目标端的replicate配置

GGSCI (bsr.com) 3> dblogin userid ogg,password a

–添加检查点表(强列建议为每个Replicat进程创建checkpointtable)

GGSCI (bsr.com) 4> add checkpointtable ogg.rpt_app_ckpt

Successfully created checkpoint table ogg.rpt_app_ckpt.

–注意这里的trail要和源端的rmttrail一致

GGSCI (bsr.com) 6> add replicat rpt_app,exttrail ./dirdat/t1,checkpointtable ogg.rpt_app_ckpt

REPLICAT added.

附注:

GGSCI (bsr.com) 10> delete replicat RPT_APP

Deleted REPLICAT RPT_APP.

–对于replicat有checkpoint表在ogg用户上，所以建议到ogg用户下删除相关表

如:checkpointtable RPT_APP_CKPT2

则对应的表有两张

RPT_APP_CKPT2_LOX TABLE

RPT_APP_CKPT2 TABLE
