安装环境：
Oracle_HOME = /home/oracle/oracle/product/11.2.0/db_1
ORACLE_HOME/network/admin/listener.ora文件如下：
# listener.ora Network Configuration File: /home/oracle/oracle/product/11.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = sqtest)
(ORACLE_HOME = /home/oracle/oracle/product/11.2.0/db_1)
(SID_NAME = sqtest)
)
)
LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = drum)(PORT = 1521))
)
ADR_BASE_LISTENER = /home/oracle/oracle
ORACLE_HOME/network/admin/tnsnames.ora文件如下：
# tnsnames.ora Network Configuration File: /home/oracle/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
sqltest =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
(CONNECT_DATA =
(SID = sqtest)
)
)
执行lsnrctl start，结果如下：

在sqlplus下执行以下命令修复注册实例，
sqlplus / as sysdba
startup
alter system register;
再执行lsnrctl status命令，显示如下信息
