LINUX環境OGG同步測試

因爲剛換工作所以開始有點忙，剛閒下來就把以前的案例又重新測試給大家分享一下。本文主要記錄了測試的過程命令，雖然結果沒截圖，但是結果是ok的而且經過多次測試。如果本文中有問題的地方歡迎留言指出

環境準備(源目的相同)

創建目錄賦權

--賦權歸檔目錄
mkdir -p /u01/archivelog
chown -R oracle:oinstall /u01
chmod -R 775 /u01
--賦權軟件安裝包目錄
mkdir -p /u01/zky
chown -R oracle:oinstall /u01
chmod -R 775 /u01
--創建OGG安裝目錄
mkdir /ogg
chown -R oracle:oinstall /ogg
chmod -R 775 /ogg
--設置OGG環境變量
echo 'export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib'>>/home/oracle/.bash_profile

數據庫準備(源目的相同)

--登錄數據庫
sqlplus / as sysdba
--創建ogg賬戶
create tablespace ogg_tablespace datafile '/u01/app/oracle/oradata/ogg01.dbf' size 10m autoextend on next 5m;
create user goldengate identified by goldengate default tablespace ogg_tablespace;
grant dba to goldengate;
--查看歸檔、強制日誌模式、數據庫級別的補充日誌是否開啓（注意歸檔存放目錄）
archive log list;
select force_logging,supplemental_log_data_min from v$database;
show parameter enable_goldengate_replication;
--開啓歸檔方法
shutdow immediate
start mount
alter database archivelog;
--設置歸檔日誌路徑
alter system set log_archive_dest_1='location=/u01/archivelog' scope =both;
alter database open;
--開啓數據庫強制日誌模式、數據庫級別的補充日誌
alter database force logging;
alter database add supplemental log data;
--修改允許使用ogg的參數（針對11.2.0.4庫）
ALTER SYSTEM SET ENABLE_GOLDENGATE_REPLICATION = TRUE SCOPE=BOTH;

更改tnsname(源目的相同)

vi /u01/app/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora 
ZHANKYS =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST =192.168.214.52)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = ZHANKYS)
    )
  )
ZHANKYT =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST =192.168.214.53)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = ZHANKYT)
    )
  )

初始化數據(源目的相同)

初始化數據準備(源目的相同)（初始化就是保持兩邊數據庫的基礎數據一樣。ps：這裏因爲測試等後面有時間在從新弄一份模擬真實環境初始化）

connect goldengate/goldengate
--創建表
DROP TABLE tcustmer;
CREATE TABLE tcustmer ( cust_code VARCHAR(4) NOT NULL, name VARCHAR(30),
city VARCHAR(20), state CHAR(2), PRIMARY KEY (cust_code));
DROP TABLE tcustord;
CREATE TABLE tcustord ( cust_code VARCHAR(4) NOT NULL, product_code VARCHAR(8) NOT NULL,
order_id INTEGER NOT NULL, product_price DECIMAL(8,2), product_amount INTEGER,
transaction_id INTEGER, PRIMARY KEY (cust_code, product_code, order_id) );

select * from goldengate.tcustmer;
select * from goldengate.tcustord;

圖形化安裝OGG(源目的相同)

創建ogg目錄(源目的相同)

cd /ogg

創建checkpoint表(源目的相同)（如果有多實例的時候需要在dblogin的時候@庫名：dblogin userid goldengate@庫名,password goldengate）

{
dblogin userid goldengate,password goldengate
add checkpointtable goldengate.ggs_checkpoint
}

設置globals(源目的相同)

edit params ./globals
