今天有个朋友出现了这么一个情况,在使用pl/sql连接数据库的时候提示ORA-12537:TNS:连接关闭。
今天有个朋友出现了这么一个情况,,在使用pl/sql连接数据库的时候提示ORA-12537:TNS:连接关闭。
查看过程(为了保密,特模拟过程):
查看过程:
1)查看客户端tnsname.ora文件信息如下:
# tnsnames.ora Network Configuration File: E:\softsetup\Oracle_client\oracle_base\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.
RHYS =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.101)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = RHYS)
)
)
没有问题
2)查看服务器监听状态
[oracle@oracle-one ~]$ lsnrctl status
