ORA-00119错误处理
今天做实验为了好识别机器随手用 hostname source 命令更改了linux主机名然后启动数据库报如下错误：
[Oracle@source dbs]$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.2.0 Production on Sat Aug 24 20:11:43 2013

SQL> startup
ORA-00119: invalid specification for system parameter LOCAL_LISTENER
ORA-00130: invalid listener address '(ADDRESS=(PROTOCOL=TCP)(HOST=source)(PORT=1521))'
看到此错误果断生成pfile文件，准备剔除LOCAL_LISTENER参数，然后启动数据库。待打开pfile文件发现里面根本就没有LOCAL_LISTERER参数的定义。这就奇怪了。
参数文件如下所示：
[oracle@source dbs]$ vi initCRM.ora
CRM.__pga_aggregate_target=503316480
CRM.__db_cache_size=268435456
CRM.__java_pool_size=16777216
CRM.__large_pool_size=16777216
CRM.__oracle_base='/oracle/app'#ORACLE_BASE set from environment
CRM.__pga_aggregate_target=503316480
CRM.__sga_target=754974720

*.db_cache_size=218103808
*.db_domain=''
*.db_name='CRM'
*.diagnostic_dest='/oracle/app'
*.dispatchers='(PROTOCOL=TCP) (SERVICE=CRMXDB)'
*.log_archive_dest_1='LOCATION=/oracle/archive'

*.open_cursors=300
*.processes=150
*.remote_login_passwordfile='EXCLUSIVE'
*.undo_retention=1200
*.undo_tablespace='UNDOTBS3'
然后不死心又用pfile参数尝试启动一样报错
SQL> startup nomount pfile='/oracle/app/db1/dbs/initCRM.ora';
ORA-00119: invalid specification for system parameter LOCAL_LISTENER
ORA-00130: invalid listener address '(ADDRESS=(PROTOCOL=TCP)(HOST=source)(PORT=1521))'
于是仔细想了想，既然更改了主机名导致这个错误，查看下/etc/hosts/是否有问题，一检查果然发现是hosts文件问题
[oracle@source dbs]$ cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 oracle localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
更改后的hosts文件如下：
root@oracle ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 source localhost.localdomain localhost
更改后启动数据库正常，如下所示：
[root@oracle ~]# su - oracle
[oracle@source ~]$ sqlplus / as sysdba
