如果沒有修改參數(shù)文件中的DB_NAME參數(shù)，那么在MOUNT的時(shí)候，會(huì)報(bào)ORA-01103錯(cuò)誤。
修改DB_NAME參數(shù)，嘗試直接打開數(shù)據(jù)庫(kù)。
提示必須使用RESETLOGS的方式才能打開數(shù)據(jù)庫(kù)。
默認(rèn)情況下，db_unique_name 和service_names都會(huì)伴隨著DB NAME一起改變，此時(shí)由于service_names發(fā)生了變化，正常情況下應(yīng)用是無(wú)法連接數(shù)據(jù)庫(kù)的(以SID連接方式除外)。

備庫(kù)：
1.創(chuàng)建ogg用戶并授權(quán)
create user goldengatet identified bygoldengatet default tablespace tbs_ogg;
grant dba to ogg;
execdbms_streams_auth.grant_admin_privilege(grantee => 'ogg',grant_privileges=> true);
ALTER SYSTEM SETENABLE_GOLDENGATE_REPLICATION = TRUE SCOPE=BOTH;
2.配置環(huán)境變量（oracle用戶下）

參數(shù)介紹：
REPLICAT RINI_1：說明這是REPLICAT應(yīng)用進(jìn)程，名字叫RINI_1
SETENV：語(yǔ)言變量，同捕獲進(jìn)程EINI_1
ASSUMETARGETDEFS：告訴OGG目標(biāo)端和源端需要同步的表的結(jié)構(gòu)完全一致，不需要OGG去檢查表的結(jié)構(gòu)，包括表名、字段名、字段類型、字段長(zhǎng)度等，如果目標(biāo)端和源端同步的表的結(jié)構(gòu)不一樣，需要使用SOURCEDEFS參數(shù)，詳見OGG官方文檔。
USERID、PASSWORD：同捕獲進(jìn)程EINI_1參數(shù)介紹
DISCARDFILE：錯(cuò)誤信息存放位置及命名規(guī)則
MAP：源端捕獲的表的名字
TARGET：目標(biāo)端同步的表的名字，可以不在同一SCHEMA。
