How to run SDM on OS/400

Hi Experts,

We are going to integrate XI 7.0 Server to Oracle Database, We have downloded drivers jar files which need to be deployed

in XI Server through SDM .We are using OS/400 OS.

I have edited sdm_jdk.bat as

set sdm_java_home=/QIBM/ProdData/Java400/jdk14 to set sdm_java_home=%JAVA_HOME%

and;

set sdm_heap_size=512

But still SDM is not opening and giving below error

'"java"' is not recognized as an internal or external command operable program or batch file.

Please suggest solution
