[Oracle] opiodr aborting process unknown ospid (***) as a result of ORA-609

今天線上資料庫（版本11.2.0.1）無法建立新連接配接，但原有的連接配接不受影響，alert.log報如下錯誤：

opiodr aborting process unknown ospid (22997) as a result of ORA-609

但在listener.log裡卻顯示連接配接已建立

03-APR-2014 16:05:44 * (CONNECT_DATA=(SERVICE_NAME=orcl2.localdomain)(CID=([email protected])(HOST=lx151)(USER=gl))) * (ADDRESS=(PROTOCOL=tcp)(HOST=10.10.100.151)(PORT=52903)) *establish * orcl2.localdomain * 0

在sqlnet.log裡報12537錯誤

當用lsnrctl status檢視監聽器狀态時，卡住

通過查詢官方文檔，知道這是個bug，後來根據網上搜尋的解決辦法，連結：http://forums.oracle.com/forums/thread.jspa?messageID=4489745

删除主機檔案/etc/resolv.conf，果然恢複了，具體原因不清楚，這隻是一個臨時的解決辦法，要想徹底解決，應該要更新。
