A服务器需要与C服务器通讯
企业内部
建立dblink
但是 经常性出现
ORA-12170: TNS: 连接超时
PING C主机IP,网络一直正常。
MOS
解释如下
OERR: ORA-12170 TNS:Connect timeout occurred [ID 194295.1]
--------------------------------------------------------------------------------
修改时间 21-OCT-2010 类型 REFERENCE 状态 PUBLISHED
{ This note contains error information about an "Oracle Server"
error number. It may contain additional support notes as
described in Note:22080.1 }
Error: ORA-12170 (ORA-12170)
Text: TNS:Connect timeout occurred
---------------------------------------------------------------------------
Cause: The server shut down because connection establishment with a
client failed to complete within the allotted time interval. This
may be a result of network/system delays; or this may indicate
that a malicious client is trying to cause a Denial of Service
attack on the server.
Action: If the error occurred because of a slow network/system,
reconfigure the SQLNET.INBOUND_CONNECT_TIMEOUT parameter in
sqlnet.ora to a larger value. If a malicious client is suspected,
use the address in sqlnet.log to identify the source and restrict
access. Note that logged addresses may not be reliable as they can
be forged (e.g. in TCP/IP).

其它与C服务器通讯的D、E、F等服务器均无此情况。
不知道该怎么测试了,请 Liu_Maclean 指点 |
