配置静态监听sid_name大小写造成无法登录

对于Oracle数据库来说同样的名字不一样的大小写表示完全不同的数据库实例。一旦静态监听的实例名字与对应的数据库实例不一致时，

配置静态监听时sid_name名字大小写造成的远程登录失败。

对于Oracle数据库来说同样的名字不一样的大小写表示完全不同的数据库实例。一旦静态监听的实例名字与对应的数据库实例不一致时，便会出现无法连接数据库的问题。

【Oracle】静态监听导致的ORA-12523错误

Oracle静态监听配置示例

Oracle DBA之配置静态监听（listener registered statically）

由于原来的1521端口要给另一个实例使用,现在的这个实例要使用另外的端口客户的就使用静态监听在设置完重启监听后远程登录出错.

 SQL> conn test/test@127
 ERROR:
 ORA-01034: ORACLE not available
 ORA-27101: shared memory realm does not exist

查看oracle home目录和oracle_sid
 [oracle@ggfwweb admin]$ echo $ORACLE_HOME
 /u01/app/oracle/10gR2/db
 [oracle@ggfwweb admin]$ echo $ORACLE_SID
 hygeia
 [oracle@ggfwweb admin]$ ps -ef | grep pmon
 oracle  25830    1  0 09:39 ?        00:00:00 ora_pmon_hygeia
 oracle  25950 25585  0 09:59 pts/1    00:00:00 grep pmon
 

查看监听文件文件
 [oracle@ggfwweb admin]$ cd $ORACLE_HOME/network/admin
 [oracle@ggfwweb admin]$ ls
 listener.ora  listener.ora.bak  samples  shrept.lst  tnsnames.ora
 [oracle@ggfwweb admin]$ cat listener.ora
 # listener.ora Network Configuration File: /u01/app/oracle/10gR2/db/network/admin/listener.ora

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /u01/app/oracle/10gR2/db)
      (PROGRAM = extproc)
  )
    (SID_DESC =
      (GLOBAL_DBNAME = HYGEIA)
      (ORACLE_HOME = /u01/app/oracle/10gR2/db)
      (SID_NAME = HYGEIA)
    )
  )
 

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST =10.142.11.108)(PORT = 1568))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
  )
 可以看到监听文件中使用的是HYGEIA,而ORACLE_SID是hygeia
 

将SID_NAME=HYGEIA修改为SID_NAME=hygeia后重启监听
