Linux下启动Oracle11g数据库监听问题的解决

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：

TNSLSNR for Linux: Version 11.2.0.1.0 - Production
System parameter file is /home/oracle/oracle/product/11.2.0/db_1/network/admin/listener.ora

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

发现数据库实例已经注册监听成功。

关闭的步骤如下：

sqlplus下执行

shutdown

exit
