我在Linux机器上安装了Oracle Database 11gR2以及Oracle Grid Infrastructure,然后创建了orcl
数据库。
我一直能够使用SQL * Plus或OEM连接到我的数据库。但是最近,我在输入命令lsnrctl status
时遇到了问题,因此我无法连接到数据库。
我的listener.ora
文件:
# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/grid/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = pc.company.com)(PORT = 1521))
)
)
ADR_BASE_LISTENER = /u01/app/oracle
我的tnsnames.ora文件:
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = pc.company.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl.example.com)
)
)
输入lsnrctl status
时,我会收到以下信息:
LSNRCTL for Linux: Version 11.2.0.1.0 - Production on 21-JUL-2014 03:35:48

Listening Endpoints Summary...

The listener supports no services
The command completed successfully
在输入sqlplus / as sysdba
然后startup
时,我明白了:
ORA-01078: failure in processing system parameters
ORA-01565: error in identifying file '+DATA/orcl/spfileorcl.ora'
ORA-17503: ksfdopn:2 Failed to open file +DATA/orcl/spfileorcl.ora
ORA-29701: unable to connect to Cluster Synchronization Service
srvctl start database
命令也无法启动数据库。
我的oratab
文件如下:

#
# This file is used by ORACLE utilities. It is created by root.sh

# A colon, ':', is used as the field terminator. A new line terminates
# the entry. Lines beginning with a pound sign, '#', are comments.
#
# Entries are of the form:

#
# The first and second fields are the system identifier and home
# directory of the database respectively. The third filed indicates

# "N", be brought up at system boot time.

# Multiple entries with the same $ORACLE_SID are not allowed.

数据库在启动时向侦听器注册其服务名称。如果它无法这样做,那么它会定期再次尝试 - 所以如果监听器在数据库之后启动,那么在识别服务之前可能会有一段延迟。
如果数据库没有运行,则没有任何内容会注册该服务,因此您不应期望听众了解它 - lsnrctl status
或lsnrctl services
赢了&# 39; t报告尚未注册的服务。
您可以在没有监听器的情况下启动数据库;从Oracle帐户开始,您可以使用ORACLE_HOME
,ORACLE_SID
和PATH
设置:
sqlplus /nolog
然后从SQL * Plus提示符:
connect / as sysdba
startup
或者通过网格基础架构,从网格帐户中使用srvctl start database
command:
srvctl start database -d db_unique_name [-o start_options] [-n node_name]
您可能希望查看数据库是否设置为oratab
文件中的自动启动,具体取决于您使用的是否应该自动启动。如果您期望它正在运行而且它不是,或者您尝试启动它并且它不会出现,那么这是一个完全不同的场景 - 您是需要查看错误消息,警报日志,可能跟踪文件等,以确切了解它为什么不能启动,如果您无法弄清楚,可能会询问数据库管理员而不是堆栈溢出
如果数据库看不到+DATA
,那么ASM可能没有运行;你可以see how to start that here;或使用srvctl start asm
。正如文档所述,请确保从网格主页而不是数据库主页执行此操作。

您需要重新配置tnsnames.ora,以便它可以指向您的主机名 之后,监听器将能够选择新的主机名。之后检查监听器lsnrctl状态的状态并启动监听器lsnrctl start 然后注册你的听众。改变系统寄存器

检查spfile或pfile中的local_listener定义。在我的情况下,问题出在pfile上,我已经从类似的环境中移动了pfile,它将LISTENER_sid视为LISTENER而不仅仅是LISTENER。
答案 3 :(得分:0)
您需要在listener.ora文件中添加ORACLE_HOME
定义。目前,它尚未在任何ORACLE_HOME
中注册。
样本listener.ora
abc =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = abc.kma.com)(PORT = 1521))
)
)
SID_LIST_abc =
(SID_LIST =
(SID_DESC =
(ORACLE_HOME= /abc/DbTier/11.2.0)
(SID_NAME = abc)
)
)

对于不支持监听器的服务,您可以使用以下命令在spfile中使用监听器端口和服务器ip地址设置local_listener参数
更改系统设置local_listener ='(DESCRIPTION = {ADDRESS = {PROTOCOL = tcp)(HOST = 192.168.1.101)(PORT = 1520)))'sid ='testdb'scope = spfile;
