ORA-28544: connect to agent failed, probable Net8 administration error

ORA-28544: connect to agent failed, probable Net8 administration error
Cause: Net8 reported a failure to make a RSLV connection or a protocol mode error when the Oracle server attempted to establish communication with a Heterogeneous Services agent or an external procedure agent. This usually is due to an administration error in setting up Net8 service definitions in TNSNAMES.ORA or LISTENER.ORA: A basic network connection is opened, but it connects to a program which does not use the appropriate protocol. This often is a sign that the connection goes to the wrong program.
Action: Check Net8 administration in the following ways: -- When using TNSNAMES.ORA or an Oracle Names server, make sure that the connection from the ORACLE server uses the correct service name or SID. -- Check LISTENER.ORA on the agent's host machine to assure that the service name or SID refers to the correct agent executable in its (PROGRAM=...) clause. -- Confirm in TNSNAMES.ORA or the equivalent service definition that sevice 'extproc_connection_data' does NOT contain (HS=), or that the service definition used by a Heterogeneous Services database link DOES contain (HS=).

ORA-28544：连接到代理失败，可能的Net8管理错误,
.原因：当Oracle服务器尝试与异构服务代理或外部过程代理建立通信时，Net8报告无法建立RSLV连接或协议模式错误。这通常是由于在TNSNAMES.ORA或LISTENER.ORA中设置Net8服务定义时出现管理错误：打开了基本网络连接，但它连接到不使用适当协议的程序。这通常是一个标志，连接到错误的程序。,
.操作：以下列方式检查Net8管理： - 当使用TNSNAMES.ORA或Oracle Names服务器时，请确保来自ORACLE服务器的连接使用正确的服务名称或SID。 - 检查代理主机上的LISTENER.ORA，以确保服务名称或SID指向其（PROGRAM = ...）子句中的正确代理可执行文件。 - 在TNSNAMES.ORA或服务'extproc_connection_data'不包含（HS =）的等效服务定义中确认，或者异构服务数据库链接使用的服务定义包含（HS =）。,
