安装oracle之后执行dbca的时候报错；

sh:/bin/ksh:Nosuch file or directory

怀疑是没有安装ksh包，yum installksh

搞定！

File “/etc/oratab” is not accessible

原来是没有执行root.sh脚本，在oracle的家目录下（cd$ORACLE_HOME）product/11.2.0/db_1/ 目录下执行./root.sh

执行之后还是有报错，

ORA-00119: invalid specification for system parameter LOCAL_LISTENER
ORA-00132: syntax error or unresolved network name'LISTENER_ORCL'

怀疑是监听的问题，lsnrctlstart启动失败，具体的报错信息既不清楚了，于是重新添加监听。

执行netca的时候报错；

TNS-12545Connectfailedbecausetargethostorobjectdoesnotexist

经过检查是由于tnsname.ora文件不存在导致的，因为oracle不是我安装的，不太清楚为什么没有这个文件。于是从其他服务器上拷贝了一份过来：

# tnsnames.ora Network Configuration File:/u01/app/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora

# Generated by Oracle configuration tools.

Oracle11g=

(DESCRIPTION =

(ADDRESS = (PROTOCOL =TCP)(HOST = *.*.*.*)(PORT = 1521))

)

(CONNECT_DATA =

)

ORCL =

(DESCRIPTION =

(SERVICE_NAME = orcl)

)

拷贝之后执行lsnrctl,监听启动成功。

执行startup的时候
