ORACLE_关于OGG参数.ENABLE_GOLDENGATE_REPLICATION
下面客户现场包的错：
2014-03-20 13:27:40 INFO OGG-01815 Oracle GoldenGate Delivery for Oracle, rdb3mis.prm: Virtual Memory Facilities for: COM anon alloc: mmap(MAP_ANON) anon free: munmap

2014-03-20 13:27:40 ERROR OGG-02091 Oracle GoldenGate Delivery for Oracle, rdb3mis.prm:
Operation not supported because enable_goldengate_replication is not set to true.
DB Version: 11.2.0.4 Goldengate Version: 1121016_Linux-x86-64
先字面分析一下错误，第一个，是GG的处理机制出现了问题。第二个，要求设置DB 参数 enable_goldengate_replication 为true.（没见过）
APPLIES TO:
Oracle GoldenGate - Version 11.2.0.0.0 and later
Information in this document applies to any platform.
PURPOSE
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.
这个参数在11.2.0.4和12.1.0.2以后才出现。
DETAILS
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.
上面的意思是为了更好的监视你使用OGG，所以把gg绑定到DB中，只有设置了改参数为true,才能使用OGG的一些功能。
So, in order to use OGG, on Oracle 11.2.0.4, or Oracle 12.1.0.2+, you will need to issue the following command through SQL*Plus.
ALTER SYSTEM SET ENABLE_GOLDENGATE_REPLICATION = TRUE SCOPE=BOTH;
This only needs to be done once, and in a RAC environment, will take effect on all instances. It can be done without bouncing the database instance, and you’ll want to use SCOPE=BOTH or update the init.ora file to ensure that when the database is bounced, the setting remains in effect.
以后对操作GG的用户还要设置权限。
If this parameter is not set and/or missing privileges (exec DBMS_GOLDENGATE_AUTH.GRANT_ADMIN_PRIVILEGE ( '' ); exec DBMS_XSTREAM_AUTH.GRANT_ADMIN_PRIVILEGE ( '' );), you may get an Oracle error, ORA-26947 or ORA-26945 when attempting to use any of the GoldenGate functionality.
Here is the complete text of the oracle error (as shown from orerr utility)
26947, 00000, "Oracle GoldenGate replication is not enabled."
// *Cause: The 'enable_goldengate_replication' parameter was not set to 'true'.
// *Action: Set the 'enable_goldengate_replication' parameter to 'true'
// and retry the operation.
// Oracle GoldenGate license is needed to use this parameter.
To correct, grant privileges to the Replicat Oracle DB user by running the dbms_goldengate_auth.grant_admin_privilege procedure.
ie:
exec dbms_goldengate_auth.grant_admin_privilege('gguser','*',TRUE);
下面报错以上由于没设参数以及授予权限，通过上面两步解决。
