有没有简单方法通过命令行列出系统中所有可用的tnsnames?
每当需要查找tnsname时,我只需使用 tnsping 命令搜索 tnsnames.ora 文件,然后在文本编辑器中打开它以进行扫描。然后,随后运行 tnsping [tnsname] 来检查连接运行状况。我在想是否有像 tnslist或tns -l 这样的简单命令列出所有tnsname,但我找不到。
最佳答案
假设您有一个tnsnames.ora
文件:
DB01 =
(DESCRIPTION =
(FAILOVER=off)
(LOAD_BALANCE=off)
(ADDRESS = (PROTOCOL = TCP)(HOST = db01-vip)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = mydb1)
)
)
DB02 =
(DESCRIPTION =
(FAILOVER=off)
(LOAD_BALANCE=off)
(ADDRESS = (PROTOCOL = TCP)(HOST = db02-vip)(PORT = 1531))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = mydb2)
)
)
像这样编辑您的.profile或.bash_profile:
ORACLE_HOME=/u01/app/oracle/product/12.1.0.2/dbhome_1; export ORACLE_HOME
...
alias lstns="sed -n '/DESCR/{x;p;d;}; x' $ORACLE_HOME/network/admin/tnsnames.ora | sed "s/=/${s}/""
echo 'lstns : tnsnames.ora listing'
lstns : tnsnames.ora listing
DB01
DB02
