NSA (nimsoft scripting agent) : Error: Fail to load Oracle DLL

DX Unified Infrastructure Management (Nimsoft / UIM)


My Lua script is trying access UIM database running on oracle but getting the following error. The script is running on a robot server with nsa.exe.
Oracle instant client is installed on the server and LD_LIBRARY_PATH is setup but still getting this error. Please help me to jump over this hurdle.

1- Install oracle 12.x 32 bit client including ODBC drivers
2- Validate the Oracle driver appears in the windows 32 bit ODBC administrator

3- Used the following code:
print("Start database connection 1")
-- Connect to the database
local oracle_server = "oracle server hostname or IP"
local oracle_user = "oracle user"
local oracle_pwd = "oracle user password"
local oracle_service = "oracle service name (as returned by "select * from global_name;")
local oracle_port = "1521"
local oracle_database= "CA_UIM"
local database_driver = "Oracle in OraClient12Home1_32bit"

if oracle_pwd ~= "" then
    -- Build connection string
       local cs = "Driver={"..database_driver.."};Dbq=//"..oracle_server..":"..oracle_port.."/"..oracle_service..";Uid="..oracle_user..";Pwd="..oracle_pwd..""
      print (cs)
    local rc =,false)
    if rc == NIME_OK then
        local rs = database.query ("SELECT * FROM CA_UIM.CM_COMPUTER_SYSTEM")
        printf ("Number of QoS objects: %d",#rs)
            for i=1,#rs do
               print("Name Column has: " .. rs[i].NAME .. ", CS_ID Column has: " .. rs[i].CS_ID)


        print ("Failed to open database using the provided connection string!")
