《卸甲笔记》-Oracle线下迁移到PPAS
本文共 15928 字，大约阅读时间需要 53 分钟。
迁移原则
1、尽量保持Oracle与PPAS一致，这会使得日后应用程序迁移更为简单
2、迁移前检查PPAS中是否有同名帐号及同名的Schemaa）如果有，建议考虑删除或改名b）如果没有，先手工建立与Oracle同名的帐号及Schema
3、用MTK迁移时，配置文件中目标数据库建议使用与Oracle同名的帐号（如本案例中使用scott），这样可以保持目标数据库中所有表和对象的主属用户都和Oracle中一致
一 环境准备
Oracle环境(OS:Linux)
a) IP:192.168.1.113，管理员用户 ：sys，system，SID：prodb) 普通用户scott，密码 scottc) Oralce 源数据库分析
PPAS环境(OS:Linux,IP:192.168.1.116) a) 安装PPAS [root@test06 PPAS9.3GA]#tar zxvf ppasmeta-9.3.1.3-linux-x64.tar.gz[root@test06 PPAS9.3GA]# cd ppasmeta-9.3.1.3-linux-x64[root@test06 ppasmeta-9.3.1.3-linux-x64]# setenforce Permissive[root@test06 ppasmeta-9.3.1.3-linux-x64]# ./ppasmeta-9.3.1.3-linux-x64.run --mode textLanguage SelectionPlease select the installation language[1] English - English[2] Japanese - 日本語[3] Simplified Chinese - 简体中文[4] Traditional Chinese - 繁体中文[5] Korean - 한국어Please choose an option [1] : ----------------------------------------------------------------------------Welcome to the Postgres Plus Advanced Server Setup Wizard.--------------------------------------------------------------------------------------------------------------------------------------------------------Please specify the directory where Postgres Plus Advanced Server will be installed.Installation Directory [/opt/PostgresPlus/9.3AS]: ----------------------------------------------------------------------------Select the components you want to install.Database Server [Y/n] :YConnectors [Y/n] :YInfinite Cache [Y/n] :YMigration Toolkit [Y/n] :YPostgres Enterprise Manager Client [Y/n] :Ypgpool-II [Y/n] :YEDB*Plus [Y/n] :YSlony Replication [Y/n] :YPgBouncer [Y/n] :YIs the selection above correct?

b) PPAS pg_hba.conf文件基础配置
-bash-4.1$ vim /opt/PostgresPlus/9.3AS/data/pg_hba.confhost all all 0.0.0.0/0 md5
c) 重新启动PPAS服务
[root@test06 data]# /etc/init.d/ppas-9.3 restartRestarting Postgres Plus Advanced Server 9.3: waiting for server to shut down.... doneserver stoppedwaiting for server to start.... doneserver startedPostgres Plus Advanced Server 9.3 restarted successfully
d) Oracle Client安装
[root@test06 ppasmeta-9.3.1.3-linux-x64]# rpm -ql oracle-instantclient11.2-basic-11.2.0.1.0-1.x86_64package oracle-instantclient11.2-basic-11.2.0.1.0-1.x86_64 is not installed[root@test06 oralceclient]# lsoracle-instantclient11.2-basic-11.2.0.1.0-1.x86_64.rpm[root@test06 oralceclient]# rpm -ivh oracle-instantclient11.2-basic-11.2.0.1.0-1.x86_64.rpm Preparing... ########################################### [100%] 1:oracle-instantclient11.########################################### [100%][root@test06 oralceclient]# rpm -ql oracle-instantclient11.2-basic-11.2.0.1.0-1.x86_64/usr/lib/oracle/11.2/client64/bin/adrci/usr/lib/oracle/11.2/client64/bin/genezi/usr/lib/oracle/11.2/client64/lib/libclntsh.so.11.1/usr/lib/oracle/11.2/client64/lib/libnnz11.so/usr/lib/oracle/11.2/client64/lib/libocci.so.11.1/usr/lib/oracle/11.2/client64/lib/libociei.so/usr/lib/oracle/11.2/client64/lib/libocijdbc11.so/usr/lib/oracle/11.2/client64/lib/ojdbc5.jar/usr/lib/oracle/11.2/client64/lib/ojdbc6.jar/usr/lib/oracle/11.2/client64/lib/xstreams.jar
e) JDK确认（1.6以上）
[root@test06 ppasmeta-9.3.1.3-linux-x64]# rpm -qa|grep javajava-1.7.0-openjdk-devel-1.7.0.45-2.4.3.3.el6.x86_64java-1.7.0-openjdk-1.7.0.45-2.4.3.3.el6.x86_64tzdata-java-2013g-1.el6.noarchgcc-java-4.4.7-4.el6.x86_64java_cup-0.10k-5.el6.x86_64java-1.5.0-gcj-1.5.0.0-29.1.el6.x86_64java-1.6.0-openjdk-1.6.0.0-1.66.1.13.0.el6.x86_64libvirt-java-0.4.9-1.el6.noarchjava-1.6.0-openjdk-devel-1.6.0.0-1.66.1.13.0.el6.x86_64libvirt-java-devel-0.4.9-1.el6.noarch[root@test06 ppasmeta-9.3.1.3-linux-x64]# which java/usr/bin/java[root@test06 ppasmeta-9.3.1.3-linux-x64]# ll /usr/bin/javalrwxrwxrwx. 1 root root 22 Jun 13 2016 /usr/bin/java -> /etc/alternatives/java
f) JDBC配置

二、迁移测试
在PPAS中建立测试用户及数据库
[root@test06 ppasmeta-9.3.1.3-linux-x64]# su – enterprisedb-bash-4.1$ psqlpsql.bin (9.3.1.3)Type "help" for help.edb=# create user scott password 'scott' createrole createuser createdb login;CREATE ROLEedb=# create database scott owner scott;CREATE DATABASE
MTK配置文件toolkit.properties

运行/runMTK.sh进行数据迁移
[root@test06 etc]# cd /opt/PostgresPlus/9.3AS/bin/[root@test06 bin]# ./runMTK.sh scottSource database connectivity info...conn =jdbc:oracle:thin:@192.168.1.113:1521:produser =scottpassword=******Target database connectivity info...conn =jdbc:edb://localhost:5444/scottuser =scottpassword=******Connecting with source Oracle database server...Connecting with target EnterpriseDB database server...Importing redwood schema scott...Creating Schema...scott Creating Tables...Creating Table: BONUSCreating Table: DEPTCreating Table: EMPCreating Table: SALGRADECreated 4 tables.Loading Table Data in 8 MB batches...Loading Table: BONUS ...[BONUS] Table Data Load Summary: Total Time(s): 0.04 Total Rows: 0Loading Table: DEPT ...[DEPT] Migrated 4 rows.[DEPT] Table Data Load Summary: Total Time(s): 0.01 Total Rows: 4Loading Table: EMP ...[EMP] Migrated 14 rows.[EMP] Table Data Load Summary: Total Time(s): 0.049 Total Rows: 14Loading Table: SALGRADE ...[SALGRADE] Migrated 5 rows.[SALGRADE] Table Data Load Summary: Total Time(s): 0.008 Total Rows: 5Data Load Summary: Total Time (sec): 0.371 Total Rows: 23 Total Size(MB): 0.0Creating Constraint: PK_DEPTCreating Constraint: PK_EMPCreating Constraint: FK_DEPTNOSchema scott imported successfully.Creating User: SCOTTError Creating User SCOTT (由于已经在目标端数据库创建了一个名为scott的用户，所以重新创建同名Scott用户时出错，如果目标端没有scott用户则不会出现错误。)One or more schema objects could not be imported during the migration process.
