0509-036 Cannot load program brconnect

Question

Hello Guru,
Good day!
Im having problem in running jobs in DB13 as we encounter error below.
I also encounter this in the same system when I tried to execute brtools to extend tablespace and I was able to resolved by setting environment of LIBPATH. 
for your information I was able to run the brconnect -u / -c -f cleanup from the OS level.  But in using DB13 it was failed
Do you any idea how to resolve it?

You are missing the Oracle 10g instantclient, the client software is no more linked from /oracle/<SID>/102_64 to /oracle/client/<version> but you have to install it separately.
