解决ORA-02069: global_names parameter must be set to TRUE for this operation 问题

解决ORA-02069: global_names parameter must be set to TRUE for this operation 问题

问题产生背景：

多数据库分库，在各个库之间采用dblink连接，DML操作会导致该问题的产生。

解决步骤

各个数据库设置独立地global name， 并enable global name.



select * from global_name;

alter database rename global_name to MAINDB;

修改tnsnames.ora 和listener.ora.

vi $ORACLE_HOME/network/admin/tnsnames.ora

MAINDB =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.198.135)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

)

)

IPDB =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.198.136)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

)

)

vi $ORACLE_HOME/network/admin/listener.ora

SID_LIST_LISTENER = (

SID_LIST = (

SID_DESC =

(GLOBAL_DBNAME = MAINDB)

(ORACLE_HOME = /db/oracle/product/11.2.0/db_1)

(SID_NAME=orcl)

)

)

各个库都要这样修改。

把DBLINK name 设置成和global name保持相同.

删除旧的db link： drop database link ORCLMAIN;

在MAINDB上建立到IPDB的link

Create database link IPDB connect to admin identified by 123

using ‘IPDB’;

从库也要建立到主库的反向DBLINK，命名原则同上.

在IPDB上建立到MAINDB的link

Create database link MAINDB connect to admin identified by 123

创建表同义词

create synonym IP_RECORD for IP_RECORD@IPDB ;
