oracle中ENABLE_GOLDENGATE_REPLICATION参数

gg版本为：112101，数据库版本为：11204

一、在部署ogg时目标端出现如下错误：

2015-03-31 00:49:34 WARNING OGG-00869 Oracle GoldenGate Delivery for Oracle, repcal01.prm: OCI Error ORA-26945: unsupported hint RESTRICT_ALL_REF_CONS (status = 26945). INSERT /*+ RESTRICT_ALL_REF_CONS */ INTO "XXXXX"."XXXXX" 
source database version 11.2.0.3.10 （aix) ogg version 11.2.1 
target database version 11.2.0.4 (linux) ogg version 11.2.1

二、错误分析：

查询文档发现oracle 11204不支持replicat进程中的DBOPTIONS DEFERREFCONST参数。如果要使这个参数正常生效必须在数据库中配置ENABLE_GOLDENGATE_REPLICATION = TRUE。

I look for this err on network,it say it is a bug,please tell me how can I solve.

Bug 17550807 : ORA-26945: UNSUPPORTED HINT RESTRICT_ALL_REF_CONS ON 11.2.0.4

三、ENABLE_GOLDENGATE_REPLICATION参数说明：

Property	Description
Parameter type	Boolean
Default value	false
Modifiable	ALTER SYSTEM
Range of values	true | false
Basic	No
Oracle RAC	All instances must have the same setting

ENABLE_GOLDENGATE_REPLICATION controls services provided by the RDBMS for Oracle GoldenGate (both capture and apply services). Set this to true to enable RDBMS services used by Oracle GoldenGate.

This parameter primarily controls supplemental logging required to support logical replication of new data types and operations. The redo log file is designed to be applied physically to a database, therefore the default contents of the redo log file often do not contain sufficient information to allow logged changes to be converted into SQL statements. Supplemental logging adds extra information into the redo log files so that replication can convert logged changes into SQL statements without having to access the database for each change. Previously these extra changes were controlled by the supplemental logging DDL. Now the ENABLE_GOLDENGATE_REPLICATION parameter must also be set to enable the required supplemental logging for any new data types or operations.

All enhancements to supplemental logging required to support logical replication are also controlled by this parameter.

The RDBMS services controlled by this parameter also include (but are not limited to):

· Transparent Data Encryption (including Tablespace Encryption) utilities used by GoldenGate Extract

· Service to read redo logs used by GoldenGate Extract

· Service to suppress triggers used by GoldenGate Replicat

· Service to handle transient duplicate handling used by GoldenGate Replicat

· Service to bypass referential integrity checking used by GoldenGate Replicat

· Services required to run Oracle GoldenGate in Integrated Extract and Integrated Replicat

四、解决方案

1.设置ENABLE_GOLDENGATE_REPLICATION参数为true

SQL> ALTER SYSTEM SET ENABLE_GOLDENGATE_REPLICATION = TRUE SCOPE=BOTH;

System altered.
