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Schema

a）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：prod
b) 普通用户scott，密码 scott
c) Oralce 源数据库分析
PPAS_Oracle
PPAS环境(OS:Linux,IP:192.168.1.116)

b) PPAS pg_hba.conf文件基础配置

-bash-4.1$ vim /opt/PostgresPlus/9.3AS/data/pg_hba.conf
host    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 restart
Restarting Postgres Plus Advanced Server 9.3: 
waiting for server to shut down.... done
server stopped
waiting for server to start.... done
server started

lrwxrwxrwx. 1 root root 22 Jun 13  2016 /usr/bin/java -> /etc/alternatives/java

f) JDBC配置

 [root@test06 ext]# cp /usr/lib/oracle/11.2/client64/lib/ojdbc6.jar /usr/lib/jvm/jre-1.7.0/lib/ext/
[root@test06 ext]# ls

gnome-java-bridge.jar  meta-index      pulse-java.jar  sunpkcs11.jar

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$ psql
psql.bin (9.3.1.3)
Type "help" for help.
edb=# create user scott password 'scott' createrole createuser createdb login;
CREATE ROLE
edb=# create database scott owner scott;
CREATE DATABASE

MTK配置文件toolkit.properties

/opt/PostgresPlus/9.3AS/etc/toolkit.properties
[root@test06 etc]# vim toolkit.properties

SRC_DB_USER=scott
SRC_DB_PASSWORD=scott

TARGET_DB_URL=jdbc:edb://localhost:5444/scott
TARGET_DB_USER=scott

运行/runMTK.sh进行数据迁移

Creating User: SCOTT
Error 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. Please review the migration output for more details.
