TNS-03505 名稱無法解析,tns-03505名稱解析

TNS-03505 名稱無法解析問題現象:
[oracle@db01 admin]$ tnsping priTNS Ping Utility for Linux: Version 11.2.0.4.0 - Production on 15-JUN-2015 21:57:52Copyright (c) 1997, 2013, Oracle.  All rights reserved.Used parameter files:TNS-03505: Failed to resolve name[oracle@db01 admin]$ sqlplus system/oracle@priSQL*Plus: Release 11.2.0.4.0 Production on Mon Jun 15 21:58:48 2015Copyright (c) 1982, 2013, Oracle.  All rights reserved.ERROR:ORA-12154: TNS:could not resolve the connect identifier specifiedEnter user-name: ^C

問題分析:    出現該問題的原因通常有兩個:1、名稱不存在  2、tns設定檔不存在。

問題處理:1、首先檢查tnsnames.ora的所有配置資訊,一切正常沒有任何問題。
[oracle@db01 admin]$ cat tnsname.ora pri =  (DESCRIPTION =    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.50)(PORT = 1521))    (CONNECT_DATA =      (SERVER = DEDICATED)      (SERVICE_NAME = woo)    )  )

2、檢查tnsnames.ora的檔案及檔案所屬使用者及使用者組  
[oracle@db01 admin]$ ll tnsnames.ora -rwxr--r-- 1 oracle oinstall 350 Jun 16 22:04 tnsname.ora#從這裡來看也是沒有問題,檔案是屬於oinstall使用者組,及其所有許可權也是Oracle

3、那麼這個時候我們選擇跳過tnsnames.ora通過手工登陸進行驗證資料庫是否正常
[oracle@db01 admin]$ sqlplus system/oracle@192.168.1.50/wooSQL*Plus: Release 11.2.0.4.0 Production on Tue Jun 16 22:34:40 2015Copyright (c) 1982, 2013, Oracle.  All rights reserved.Connected to:Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - ProductionWith the Partitioning, Oracle Label Security, OLAP, Data Mining,Oracle Database Vault and Real Application Testing options              SQL> select name from v$database;NAME---------WOOSQL> select instance_name,status from v$instance;INSTANCE_NAME    STATUS---------------- ------------woo              OPENSQL> --從這裡我們可以看到,資料庫肯定是沒有問題的,那麼下一步我們通過拿一個好的監聽檔案替換這個監聽檔案來處理該問題。

4、通過上傳一個之前可用的監聽設定檔進行對比
[oracle@db01 admin]$ lslistener.ora  samples  shrept.lst  sqlnet.ora  tnsname.ora  tnsnames.ora[oracle@db01 admin]$ chmod u+x tnsnames.ora [oracle@db01 admin]$ lltotal 24-rwxr-xr-x 1 oracle oinstall  711 Jun 16 22:08 listener.oradrwxr-xr-x 2 oracle oinstall 4096 Jun 11 21:56 samples-rw-r--r-- 1 oracle oinstall  381 Dec 17  2012 shrept.lst-rw-r--r-- 1 oracle oinstall  221 Jun 16 21:59 sqlnet.ora-rwxr--r-- 1 oracle oinstall  350 Jun 16 22:31 tnsname.ora-rwxr--r-- 1 oracle oinstall  350 Jun 16 22:04 tnsnames.ora        #這個是後面上傳的#通過對比,我發現之前手工些的那個檔案名稱不對,即使裡面內容正確也無濟於事。

5、通過修改替換監聽檔案,該問題得到解決:
[oracle@db01 admin]$ cat tnsname.ora > tnsnames.ora[oracle@db01 admin]$ rm -rf tnsname.ora [oracle@db01 admin]$ sqlplus system/oracle@priSQL*Plus: Release 11.2.0.4.0 Production on Tue Jun 16 23:02:15 2015Copyright (c) 1982, 2013, Oracle.
