開啟Oracle 9i Client sqlnet trace@Windows

最近發現資料庫連接到另一台有問題,但又馬上好了...下次如果再發生 可以開啟sqlnet trace...

Fatal NI connect error 12541, connecting to:

進到C:\oracle\ora92\network\ADMIN\下,

建立一個sqlnet.ora 檔案 與
                空白資料夾trace

sqlnet.ora內容如下

DIAG_ADR_ENABLED = OFF TRACE_LEVEL_CLIENT = SUPPORT TRACE_DIRECTORY_CLIENT = C:\oracle\ora92\network\ADMIN\trace

確認設定完畢後 使用sqlplus 連接

就會發現client 連接的trace log已經被產生
