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-12545 Connect failed because target host or object does not exist
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.

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

)
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL =TCP)(HOST = oracle)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
拷贝之后执行lsnrctl,监听启动成功。
执行startup的时候
