合 OGG从入门到高可用系列
【OGG】OGG的下载和安装篇
实验环境介绍
11.2.0.3 RHEL6.5
本文简介
有个同事喊我解决OGG不能同步的问题,汗颜啊,我也就之前学过安装和简单的配置,当时是成功的,结果帮同事搭建的时候数据死活不能同步。于是下决心这几天好好再研究一下OGG的内容。
OGG安装
在Linux上安装OGG很简单,总体分为以下几个部分:
- Downloading Oracle GoldenGate software.
- Setting ORACLE_HOME and ORACLE_SID
- Setting library paths for dynamic builds
- Installing the Oracle GoldenGate software
Downloading Oracle GoldenGate software.
第一步,下载gg软件,可以有2种途径直接下载
第一种: http://edelivery.oracle.com
1. On a browser, go to http://edelivery.oracle.com
2. Welcome page:
- Select language
- Continue
3. Export Validation:
- Enter your name, company, email, country
- Accept Trial License (even if you have permanent license)
- Accept Export Restrictions
- Continue
4. Media Pack Search:
Select a Product Pack: Oracle Fusion Middleware
Select a platform from the drop-down list
Go
5. Results:
Select the Oracle GoldenGate Media Pack you want
Continue
6. View Readme
7. Download software
8. Download documentation
第二种:http://www.oracle.com
- 登录www.oracle.com ,选择Middleware下的See All
- 选择GoldenGate
注意选择好对应的版本及平台:
不用详细说明了吧,所以最终的下载地址:
英文:http://www.oracle.com/technetwork/middleware/goldengate/downloads/index.html
中文:http://www.oracle.com/technetwork/cn/middleware/goldengate/downloads/index.html
Setting ORACLE_HOME and ORACLE_SID
Set the environment variables in your .bash_profile (Bash)
ORACLE_BASE=/u01
ORACLE_HOME=$ORACLE_BASE/oracle
ORACLE_SID=ggsource
PATH=$ORACLE_BASE/gg11:$ORACLE_HOME/bin:$PATH
LD_LIBRARY_PATH=$ORACLE_BASE/gg11:$ORACLE_HOME/lib:$LD_LIBRARYPATH
export ORACLE_BASE ORACLE_HOME ORACLE_SID
export PATH LD_LIBRARY_PATH
自己:
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1
export OGG_HOME=/u01/gg11
export PATH=$OGG_HOME:$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$OGG_HOME:$ORACLE_HOME/lib:$LD_LIBRARYPATH
stty erase \^h
alias ggsci='rlwrap ggsci'
Setting library paths for dynamic builds
Platform | Environment variables |
---|---|
IBM AIX | LIBPATH |
IBM z/OS | |
HP-UX | SHLIB_PATH |
Solaris | LD_LIBRARY_PATH |
HP Tru64 | |
Linux |
Installing the Oracle GoldenGate software
Use the gzip and tar options appropriate for your system. If you are installing GoldenGate into a cluster environment, make certain that the GoldenGate binaries and files are installed on a file system that is available to all cluster nodes. After installing GoldenGate, make certain to configure the GoldenGate Manager process within the cluster application, as directed by the vendor’s documentation, so that GoldenGate will fail over properly with the other applications. The Manager process is the master control program for all GoldenGate operations.
A GoldenGate instance is a single installation of GoldenGate.
- Unzip the Oracle GoldenGate media pack .zip file on a Windows system. This produces a .tar file.
- FTP the .tar file in binary mode to the system and directory where you want GoldenGate to be installed.
- Extract the .tar file into the current directory:
tar -xvof \<filename>.tar
- Run the command shell and change directories to the new GoldenGate directory.
GGSCI> CREATE SUBDIRS
GoldenGate Directories
Directory | Contents |
---|---|
dirchk | GoldenGate checkpoint files |
dirdat | GoldenGate trail and extract files |
dirdef | Data definitions produced by DEFGEN and used to translate heterogeneous data |
dirpcs | Process status files |
dirprm | Parameter files |
dirrpt | Process report files |
dirsql | SQL scripts |
dirtmp | Temporary storage for transactions that exceed allocated memory |
a.dirchk:存放检查点文件
b.dirdat:存放Trail文件
c.dirdef:存放通过DEFGEN工具生成的源或目标端数据定义文件
d.dirpcs:存放进程状态文件
e.dirprm:存放配置参数文件
f.dirrpt:存放进程报告文件
g.dirsql:存放sql脚本文件
h.dirtmp:当食物所需要的内存超过已分配内存时,默认存储在这个目录。
系统要求
- 一个 OGG 实例最多支持 300 个并发 extract 和 replicat 进程,每个进程需要 25-55M 内存。
- GGSCI,view report,找到 PROCESS VM AVAIL FROM OS,大约就是系统所需 要的 swap space 大小
3. 磁盘空间每个实例 50-150M,外加 trail 等等,至少给 1G。trail 所需空间 的预估方法是:[log volume in one hour] x [number of hours downtime] * 0.4
4. /tmp 空间,默认是 dirtmp 目录,可以通过 CACHEMGR 参数的 CACHEDIRECTORY 选项指定
5. 安装 OGG 的用户必须属于 ORACLE 数据库实例的组,通常就是 dba。
6. 要想支持RAC里的RMAN log retention特性, 得在add extract之前安装patch BUGFIX 11879974
自己的安装例子
source和target端的安装过程是一样的。
