Zhangxiaobai teaches you how to use Ogg to synchronize Oracle 19C data with MySQL 5.7 (1)

（ One ） sketch

OGG yes Oracle GoldenGate For short , It can do Oracle Real time data synchronization to heterogeneous databases .

Use OGG complete Oracle To MySQL Synchronization of , The principle is as follows ：

Therefore, using OGG complete Oracle To MySQL Data synchronization for requires the following steps ：

（ One ） stay Oracle End installation OGG for Oracle

（ Two ） Source end OGG To configure

（1）OGG Source side related Oracle To configure （ establish c##ogg user 、 Build a test table test_ogg wait ）

（2）OGG Source side table level completion log trandata To configure

（3）OGG Source side management process MGR To configure （ Listen on local port 7809）

（4）OGG Source side extraction process extorcl To configure （ from Oracle Database tables extract data into data files ）

（5）OGG Source side transport process pumysql To configure （ Send the extracted data file to OGG Destination ）

（6）OGG Source end heterogeneity mapping file defgen Generate

（ 3、 ... and ） stay MySQL End installation OGG for MySQL

（ Four ） Destination OGG To configure

（1）OGG The end MySQL To configure

（2）OGG Destination management process MGR To configure （ Listen on local port 7810）

（3）OGG Destination checkpoint log table checkpoint To configure

（4）OGG Destination playback thread r_tab1 To configure （ Write the extracted data file to MySQL Database table ）

（ Two ） stay Oracle End installation OGG 21 for Oracle

download OGG for Oracle Installation package 213000_fbo_ggs_Linux_x64_Oracle_shiphome.zip

With Oracle The user login ：

modify .bashrc, Add the following

export JAVA_HOME=$HOME/jdk1.8.0_141export PATH=$JAVA_HOME/bin:$PATHexport TNS_ADMIN=$ORACLE_HOME/network/adminexport OGG_HOME=/opt/ogg/source_endpointexport LD_LIBRARY_PATH=$JAVA_HOME/jre/lib/amd64:$JAVA_HOME/jre/lib/amd64/server:$JAVA_HOME/jre/lib/amd64/libjsig.so:$JAVA_HOME/jre/lib/amd64/server/libjvm.so:$OGG_HOME/lib:$LD_LIBRARY_PATH:$ORACLE_HOME/lib:/usr/libexport PATH=$OGG_HOME:$PATH:$ORACLE_HOME/bin

Switch to root user

su - root

useradd ogg -g oinstall

passwd ogg

mkdir -p /opt/ogg

chown -R ogg /opt/ogg

mkdir -p /home/oracle/oradata/OGG/ORCLCDB

mkdir -p /home/oracle/oradata/OGG/tablespace

chown -R oracle:oinstall /home/oracle/oradata/OGG

Switch to ogg user ：

take ogg Installation package 213000_fbo_ggs_Linux_x64_Oracle_shiphome.zip to /home/ogg Next ：

unzip -d ~ 213000_fbo_ggs_Linux_x64_Oracle_shiphome.zip

cd fbo_ggs_Linux_x64_Oracle_shiphome/Disk1/response/

edit oggcore.rsp

Update the following lines ：

INSTALL_OPTION=ORA19CSOFTWARE_LOCATION=/opt/ogg/source_endpoint

cd ..

./runInstaller -silent -nowait -responseFile /home/ogg/fbo_ggs_Linux_x64_Oracle_shiphome/Disk1/response/oggcore.rsp

newspaper /u01/app/oracle/oraInventory No permission to write ... Checked the , Not really. , Then add permissions .

again ：

Switch to ogg user ：

cd fbo_ggs_Linux_x64_Oracle_shiphome/Disk1/

./runInstaller -silent -nowait -responseFile /home/ogg/fbo_ggs_Linux_x64_Oracle_shiphome/Disk1/response/oggcore.rsp
