ORA-28509: unable to establish a connection to non-oracle system
Cause: Initialization of a database link to a non-Oracle system failed to connect to the Heterogeneous Services agent process for this non-Oracle system.
Action: Check the Net8 service name definition in the following places: — the USING clause of the CREATE DATABASE LINK statement — the TNSNAMES.ORA file — the Oracle Names Server The following are possible reasons for name mismatches: — The USING clause in the CREATE DATABASE LINK statement has to match the service name defined in the TNSNAMES.ORA file or in the Oracle Names Server. — The protocol-specific infORMation in the service name definition must match the protocol-specific definition of the responding listener. — The SID= in the service name definition (in the TNSNAMES.ORA file or in Oracle Names Server) must match the value in the LISTENER.ORA file for the responding listener.
1.首先,检查网络连接是否正常并仔细检查服务名称,确保它是正确的,以便Oracle可以访问外部系统。
2.然后,检查外部系统中设置的网络权限和保护,如果有问题,可能需要更改来允许来自Oracle的连接。
3.最后,要检查目的地的系统,试图确定是否是DRDA和DRCP问题。
