3.安装：oracle-instantclient12.2-tools-
[root@JZGZdaping12 tools]# rpm -ivh oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm

4.添加环境变量，在文件末尾添加环境变量
[root@JZGZdaping12 tools]# vi /etc/profile
export PATH=/usr/lib/oracle/11.2/client64/bin:$PATH
export ORACLE_HOME=/usr/lib/oracle/11.2/client64/lib
export LD_LIBRARY_PATH=/usr/lib/oracle/11.2/client64/lib:$LD_LIBRARY_PATH
[root@JZGZdaping12 tools]# source /etc/profile
[root@JZGZdaping12 bin]# chmod 755 sqlldr
[root@JZGZdaping12 tools]# cd /usr/lib/oracle/11.2/client64
[root@JZGZdaping12 client64]# mkdir rdbms
sqlldr、mesg 找已安装Oracle服务到/bin 、rdbms目录下下载上传到已安装Oracle客户端服务器上
[root@JZGZdaping12 tools]# cp /home/data/tools/sqlldr /usr/lib/oracle/11.2/client64/bin
[root@JZGZdaping12 bin]# cp -r /home/data/tools/mesg /usr/lib/oracle/11.2/client64/rdbms
5.测试
/usr/lib/oracle/11.2/client64/rdbms/mesg
[root@JZGZdaping12 mesg]# sqlldr

(Default: Conventional path 64, Direct path all)
bindsize -- size of conventional path bind array in bytes (Default 256000)
silent -- suppress messages during run (header,feedback,errors,discards,partitions)
direct -- use direct path (Default FALSE)
parfile -- parameter file: name of file that contains parameter specifications
parallel -- do parallel load (Default FALSE)

PLEASE NOTE: Command-line parameters may be specified either by
position or by keywords. An example of the former case is 'sqlldr
scott/tiger foo'; an example of the latter is 'sqlldr control=foo
userid=scott/tiger'. One may specify parameters by position before
but not after parameters specified by keywords. For example,
'sqlldr scott/tiger control=foo logfile=log' is allowed, but
'sqlldr scott/tiger control=foo log' is not, even though the
position of the parameter 'log' is correct.
