我在 Linux 机器上安装了 Oracle Database 11gR2 和 Oracle Grid Infrastructure,然后我创建了 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。 ,所以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)
)
)
输入时
lsnrctl status
,我得到以下信息:LSNRCTL for Linux: Version 11.2.0.1.0 - Production on 21-JUL-2014 03:35:48

The listener supports no services
The command completed successfully
输入时
sqlplus / as sysdba
然后 startup
,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
和
srvctl start database
命令也无法启动数据库。我的
oratab
文件如下:#Backup file is /u01/app/oracle/product/11.2.0/dbhome_1/srvm/admin/oratab.bak.pc150 line added by Agent

最佳答案
数据库在启动时向监听器注册其服务名称。如果它无法这样做,则它会定期再次尝试 - 因此,如果监听器在数据库之后启动,则在识别服务之前可能会有延迟。
但是,如果数据库未运行,则不会有任何内容注册该服务,因此您不应期望监听器知道它 - lsnrctl status
或 lsnrctl services
不会报告尚未注册的服务。
你可以在没有监听器的情况下启动数据库;来自 Oracle 帐户和您的 ORACLE_HOME
, ORACLE_SID
和 PATH
设置你可以做:
sqlplus /nolog
然后从 SQL*Plus 提示符:
connect / as sysdba
startup
或者通过网格基础设施,从网格帐户,使用
srvctl start database
command :srvctl start database -d db_unique_name [-o start_options] [-n node_name]
您可能想在
oratab
中查看数据库是否设置为自动启动。文件,并取决于您使用的内容是否应该自动启动。如果您期望它运行但它没有运行,或者您尝试启动它但它不会出现,那么这是一个完全不同的场景 - 您需要查看错误消息,警报日志,可能是跟踪文件等,以确切了解为什么它不会启动,如果您无法弄清楚,可以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;您可以see how to start that here ;或使用 srvctl start asm
.正如文档所说,请确保您从网格主页而不是数据库主页执行此操作。
