Linux安装oracle客户端连接远端数据库

Linux安装oracle客户端连接远端数据库

 

方法一（不需要tnsnames.ora）：

1、安装软件（https://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html）
#rmp -ivh oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm 
#rpm -ivh oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64.rpm 
#rpm -ivh oracle-instantclient11.2-sqlplus-11.2.0.4.0-1.x86_64.rpm 
2检查
# rpm -qa|grep -i oracle
oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64
oracle-instantclient11.2-sqlplus-11.2.0.4.0-1.x86_64
oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64

3环境变量
[root@redaht69 tmp]# tail -15 /etc/profile
#oracle_client11
export ORACLE_HOME=/usr/lib/oracle/11.2/client64
#export TNS_ADMIN=$ORACLE_HOME/network/admin
export NLS_LANG='simplified chinese_china'.ZHS16GBK
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export PATH=$ORACLE_HOME/bin:$PATH

5测试
#sqlplus system/123456@//192.168.1.200:1521/orcl

# vi /tmp/tablespace.sh 
sqlplus -S /nolog <<eof
conn system/[email protected]:1521/orcl
set line 200;
set feedback off;
set pagesize 50000;
col member for a45;
select a.tablespace_name,a.summary,b.free,b.maxf "MAX_FREE_EXTENT",b.free_exts "FREE_EXTENTS",
100-b.free/a.summary*100 "USED%"
from
(select tablespace_name,sum(bytes/1024/1024) "SUMMARY" from dba_data_files
group by tablespace_name) a,
(select tablespace_name,sum(bytes/1024/1024) "FREE",max(bytes/1024/1024)
"MAXF" ,count(*) free_exts
from dba_free_space group by tablespace_name) b
where a.tablespace_name=b.tablespace_name order by 6 desc;
eof

exit;

1、安装软件
#rmp -ivh oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm 
#rpm -ivh oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64.rpm 
#rpm -ivh oracle-instantclient11.2-sqlplus-11.2.0.4.0-1.x86_64.rpm 
2检查
# rpm -qa|grep -i oracle
oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64
oracle-instantclient11.2-sqlplus-11.2.0.4.0-1.x86_64
oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64

[root@redaht69 tmp]# tail -15 /etc/profile
#oracle_client11

#export TNS_ADMIN=$ORACLE_HOME/network/admin
export NLS_LANG='simplified chinese_china'.ZHS16GBK
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export PATH=$ORACLE_HOME/bin:$PATH
4创建tnsnames.ora
vi /usr/lib/oracle/11.2/client64/network/admin/tnsnames.ora
# 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 = 192.168.1.200)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ORCL)
)
)

 

5测试
#sqlplus system/123456@orcl

# vi /tmp/tablespace.sh 
sqlplus -S /nolog <<eof
conn system/123456@orcl
set line 200;
set feedback off;
set pagesize 50000;
col member for a45;
select a.tablespace_name,a.summary,b.free,b.maxf "MAX_FREE_EXTENT",b.free_exts "FREE_EXTENTS",

"MAXF" ,count(*) free_exts
from dba_free_space group by tablespace_name) b
where a.tablespace_name=b.tablespace_name order by 6 desc;
eof

exit;
