Add tnsping into Oracle Instant Client on CentOS RHEL OEL

tnsping is a very handy tool from Oralce.
But it does not include with Oracle Instant Client!

To add it, you will need a Oracle Client software installed on the other machine with same OS (Notice:32/64 differently)

Then copy 3 files to the Oracle Instant Client folder:

scp root@192.168.1.4:/u01/app/oracle/product/10.2.0/db_1/bin/tnsping  /usr/lib/oracle/10.2.0.5/client/bin/
mkdir -p /usr/lib/oracle/10.2.0.5/client/network/mesg
scp root@192.168.1.4:/u01/app/oracle/product/10.2.0/db_1/network/mesg/tnsus.msb /usr/lib/oracle/10.2.0.5/client/network/mesg/
scp root@192.168.1.4:/u01/app/oracle/product/10.2.0/db_1/network/mesg/tnsus.msg /usr/lib/oracle/10.2.0.5/client/network/mesg/
