我在Windows Server 2008R2上運行Oracle 11g。我有一個客戶端應用程序(Zabbix)正在嘗試連接到其他地方。與即時客戶端連接時出現ora-12154問題
客戶機具有:
- 甲骨文instantclient11.2-基本-11.2.0.3.0-1.i386.rpm
- 甲骨文instantclient11.2-devel的-11.2.0.3.0 -1.i386.rpm
因此,它沒有sqlnet.ora或tnsnames.ora文件。它試圖建立與直接尋址的連接。隨着在php print語句,我看到它被調用
ociplogon(user,password,$connect);
與連接被設置爲// dbhostmachine:1521/ZABBIX。所以一切看起來都不錯。

然而,遠程我得到的流行錯誤:
ociplogon(): ORA-12154: TNS:could not resolve the connect identifier specified
奇怪的是,這是間歇性地工作之前。我會得到一個錯誤關於我的應用程序每10秒:
30923:20121101:142237.595 [Z3001] connection to database '//dbhostmachine:1521/zabbix' failed: [-1] ORA-12516: TNS:listener could not find available handler with matching protocol stack
30923:20121101:142237.596 watchdog: database is down
但肯定是在通過網絡發送的數據,並在數據庫中仍然存在。重新啓動應用程序和服務器後,我不再能夠獲得連接,並且正在研究ORA-12154
