GoldenGate单向DDL同步
1. 源库和目标库ogguser用户都赋予dba角色和执行utl_file的权限：
[oracle@dd1 ~]$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.3.0 Production on Tue Apr 16 16:15:18 2013
Copyright (c) 1982, 2011, Oracle. All rights reserved.
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
SQL> grant dba to ogguser;
Grant succeeded.
SQL> grant execute on utl_file to ogguser;
Grant succeeded.
2. 编辑源库全局参数文件
[oracle@dd1 ogg11]$ cd $ORACLE_BASE/ogg11
[oracle@dd1 ogg11]$ ggsci
Oracle GoldenGate Command Interpreter for Oracle
Version 11.1.1.1.2 OGGCORE_11.1.1.1.2_PLATFORMS_111004.2100
Linux, x64, 64bit (optimized), Oracle 11g on Oct 4 2011 23:49:46
Copyright (C) 1995, 2011, Oracle and/or its affiliates. All rights reserved.
GGSCI (dd1) 1> edit param ./GLOBALS
ggschema ogguser
3. 启用DDL支持设置（只需在源库设置）
[oracle@dd1 ogg11]$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.3.0 Production on Tue Apr 16 16:21:35 2013
