今天在一臺(tái)服務(wù)器的日志文件中，發(fā)現(xiàn)如下信息：

查看mos，有幸發(fā)現(xiàn)關(guān)于該錯(cuò)誤的相關(guān)文章

Fatal NI connect error 12170′, ‘TNS-12535: TNS:operation timed out’ Reported in 11g Alert Log [ID 1286376.1]

做了一些摘要，算是給自己做個(gè)記錄，也給不能訪問mos的朋友一個(gè)參考

1、適用范圍

Oracle Net Services - Version: 11.1.0.6 to 11.2.0.2 - Release: 11.1 to 11.2

Oracle Server - Enterprise Edition - Version: 11.1.0.6 to 11.2.0.2 [Release: 11.1 to 11.2]

Information in this document applies to any platform.

2、問題原因

These time out related messages are mostly informational in nature. The messages indicate the specified client connection (identified by the 'Client address:' details) has experienced a time out. The 'nt secondary err code' identifies the underlying network transport, such as (TCP/IP) timeout limits after a client has abnormally terminated the database connection.

The 'nt secondary err code' translates to underlying network transport timeouts for the following Operating Systems:

For the Solaris system: nt secondary err code: 145:

#define ETIMEDOUT 145 /* Connection timed out */

For the Linux operating system: nt secondary err code: 110

ETIMEDOUT 110 Connection timed out

For the HP-UX system: nt secondary err code: 238:

ETIMEDOUT 238 /* Connection timed out */

For Windows based platforms: nt secondary err code: 60 (which translates to Winsock Error: 10060)

Description: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

The reason the messages are written to the alert log is related to the use of the new 11g Automatic Diagnostic Repository (ADR) feature being enabled by default.

3、解決問題

To revert to Oracle Net Server tracing/logging, set following parameter in the server's sqlnet.ora :

DIAG_ADR_ENABLED = OFF

Also, to back out the ADR diag for the Listener component, set following parameter in the server's listener.ora:

DIAG_ADR_ENABLED_= OFF

- Where the would be replaced with the actual name of the configured listener(s) in the listener.ora configuration file. For example, if the listener name is 'LISTENER', the parameter would read:

DIAG_ADR_ENABLED_LISTENER = OFF

-Reload or restart the TNS Listener for the parameter change to take effect.

說明：這個(gè)問題是由于Automatic Diagnostic Repository中的 Oracle Net diagnostic在默認(rèn)的情況下是開啟的，當(dāng)數(shù)據(jù)庫和客戶端的連接超過特定時(shí)間，就會(huì)把這樣的信息寫入到alert日志中，所以這不是一個(gè)致命的問題，如果偶爾出現(xiàn)，可以忽略有點(diǎn)類此ora-3136的錯(cuò)誤
