OGG的Extract进程启动报错：Operation not supported because enable_goldengate_replication is not set to true

一、环境

CentOS6.9，Oracle12C，OGG18.1.0.0 for Oracle1.

二、问题

启动OGG的Extract进程，状态为STOPPED：

查看 ggserr.log日志：

more $GG_HOME/ggserr.log

错误信息为：
Operation not supported because enable_goldengate_replication is not set to true

三、解决方法

原因是Oracle的ENABLE_GOLDENGATE_REPLICATION参数未启用，将其启用即可。

参数ENABLE_GOLDENGATE_REPLICATION说明：

To better track GoldenGate product license, a new database init parameter, ENABLE_GOLDENGATE_REPLICATION, is introduced in Oracle 11.2.0.4 and 12.1.0.2 and up.
For Oracle DB versions 11.2.0.4 and 12.1.0.2 there will be a new init.ora parameter called ENABLE_GOLDENGATE_REPLICATION. In order for some of the Oracle GoldenGate functionality to work, this parameter must be set to true. It will enable access to the TDE/TSE integration with classic extract, Integrated Capture, Integrated Apply, DBLOGREADER functionality, replicat functionality like suppression of triggers and deferring referential constrains, and other integration points.
为了更好的使用OGG，只有设置了该参数为true，才能使用OGG的一些功能。

ALTER SYSTEM SET ENABLE_GOLDENGATE_REPLICATION = TRUE;

完毕。
