新版本通过ORACLE官方网站可以直接进行下载Oracle GoldenGate Downloads：
https://www.oracle.com/technetwork/middleware/goldengate/downloads/index.html。
但历史版本需要通过Delivery网站进行下载：https://edelivery.oracle.com/。
新版本的GoldenGate支持通过图形界面进行初始化安装。相比以前的操作会复杂一些，GoldenGate 11可以通过直接解压的方式进行安装。
解压软件包后，通过runInstaller命令启动安装图形界面。
[oracle@oradb1 Disk1]$ ./runInstaller
以安装OGG 12.3为例，12.3支持ORACLE 11G和 12C，因此安装过程中会进行数据库版本的选择。
GoldenGate 11可以通过直接解压的方式进行安装。
[root@gxoradb1 oracle]# cd /oracle
[root@gxoradb1 oracle]# mkdir GoldenGate
[root@gxoradb1 oracle]# chown oracle:oinstall ./GoldenGate/
[root@gxoradb1 oracle]# su - oracle

GoldenGate在Linux和Unix下安装后，需要ORACLE安装环境下的库文件才能启动，因此必须$ORACLE_HOME/lib目录配置到LD_LIBRARY_PATH环境变量中：
export ORACLE_SID=ora11g
export ORACLE_BASE=/oracle/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/database/12c
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH;
export GG_HOME=/oradata/ogg12c/ogg123
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
export NLS_DATE_FORMAT='YYYY-MM-DD HH24:MI:SS'
export PATH=$ORACLE_HOME/bin:$GG_HOME:$PATH:$HOME/bin
alias gg='cd $GG_HOME; ./ggsci'
GoldenGate 启动前，需要对ggsci应用的库文件进行检查，如果有无法找到的库文件，会导致ggsci启动失败。
[oracle@oradb1 ~]$ cd /oradata/ogg12c/ogg123
[oracle@oradb1 ogg123]$ ldd ./ggsci | grep 'not found' -> 确保所有库文件都可以找到
[oracle@oradb1 ogg123]$ ./ggsci

OPatch是ORACLE用来进行补丁安装的程序，补丁安装前，建议阅读补丁包中的说明文件，升级OPatch到官方指定的版本。
下面是MOS中OPatch的说明文档，OPatch的下载和使用可以参考该文档。
OPatch - Where Can I Find the Latest Version of OPatch(6880880)? [Video] (文档 ID 224346.1)
OPatch的替换比较简单，将p6880880_<版本>_<操作系统平台>.zip压缩包解压后，使用操作系统命令进行软件替换即可。非ORACLE用户替换OPatch目录后，需要进行权限修改。OPatch软件的版本编号(6880880)是固定的，可以在MOS上直接进行该补丁的下载。
解压最新的OPatch软件：
[oracle@oradb1 ~]$ cd /oradata/ogg12c/software/
[oracle@oradb1 software]$ unzip p6880880_122010_Linux-x86-64.zip
备份旧的OPatch软件：
[oracle@oradb1 ~]$ cd $OGG_HOME
[oracle@oradb1 ogg123]$ mv OPatch/ ./OPatch.20190425
替换新的OPatch软件，并修改软件权限：
[oracle@oradb1 ogg123]$ mv /oradata/ogg12c/software/OPatch/ ./
[oracle@oradb1 ogg123]$ chown -R oracle:oinstall ./OPatch
替换完成后，检查新的OPatch软件的版本。
[oracle@oradb1 OPatch]$ ./opatch version
OPatch Version: 12.2.0.1.17
通过MOS的补丁查找功能，可以获取当前软件的最新补丁信息。
需要注意OGG补丁是针对不同数据库的版本。下载时需要注意版本信息。
补丁程序29636573: Patch for MLR 29600067: Linux x86-64: Oracle 12c: OGG 12.3.0.1.4
查看补丁安装自述文件：
(1) Prerequisites
--------------------
Before you install or deinstall the patch, ensure that you meet the following requirements:
1. Ensure that the Oracle GoldenGate on which you are installing the patch or from which you are rolling back the patch is Oracle GoldenGate V12.3.0.1.4 for Oracle.
2. Oracle recommends you to use the latest version of OPatch.
3. Ensure that you set the ORACLE_HOME environment variable to the Oracle GoldenGate home.
4. Ensure that you set the PATH environment variable to include the location of the unzip executable, and the <ORACLE_HOME>/bin and the <ORACLE_HOME>/OPatch directories present in the Oracle GoldenGate home.
5. Ensure that you verify the Oracle Inventory because OPatch accesses it to install the patches. To verify the inventory, run the following command. If the command displays some errors, then contact Oracle Support and resolve the issue.
$ opatch lsinventory
6. Ensure that you shut down all the services running from the Oracle GoldenGate home.
7. Install the latest opatch version (i.e.,12.2.0.1.13).
8. Change file permissions for $ORACLE_HOME/crypto and $ORACLE_HOME/directc to be writable (patch will fail to install if this is not done prior to applying the opatch).
(2) Installation
-----------------
To install the patch, follow these steps:
1. Maintain a location for storing the contents of the patch ZIP file. In the rest of the document, this location (absolute path) is referred to as <PATCH_TOP_DIR>.
2. Extract the contents of the patch ZIP file to the location you created in Step (1). To do so, run the following command:
$ <PATCH_TOP_DIR> p<Patch_number>_<version>_<Platform>.zip
3. Navigate to the <PATCH_TOP_DIR>/<Patch_number> directory:
$ cd <PATCH_TOP_DIR>/<Patch_number>
4. Install the patch by running the following command:
$ opatch apply
1. 检查当前GoldenGate版本为V12.3.0.1.4
[oracle@oradb1 ogg123]$ ./ggsci
Oracle GoldenGate Command Interpreter for Oracle
Version 12.3.0.1.4 OGGCORE_12.3.0.1.0_PLATFORMS_180415.0359_FBO
2. 安装OPatch 12.2.0.1.13
[oracle@oradb1 ~]$ cd $OGG_HOME/OPatch
[oracle@oradb1 OPatch]$ ./opatch version
OPatch Version: 12.2.0.1.17
3. 设置ORACLE_HOME环境变量到Oracle GoldenGate安装目录下
[oracle@oradb1 ogg123]$ export ORACLE_HOME=$OGG_HOME
[oracle@oradb1 ogg123]$ export PATH=$ORACLE_HOME:$PATH
4. 确认Oracle GoldenGate目录下没有运行的进程
[oracle@oradb1 ogg12c]$ fuser ./ogg123/
5. 检查$ORACLE_HOME/crypto和$ORACLE_HOME/directc文件权限为可写
[oracle@oradb1 ogg123]$ ls -ld crypto
drwxr-xr-x 2 oracle oinstall 4096 Apr 24 18:46 crypto
6. 执行补丁安装
[oracle@oradb1 ~]$ cd /oradata/ogg12c/software/
[oracle@oradb1 software]$ unzip p29636573_123014_Linux-x86-64.zip
[oracle@oradb1 software]$ cd 29636573/
