The following example creates a PKCS10 certificate request for a client that can be used to send to a CA : 

createCertRequest.sh -keyStoreAlias ClientDefaultKeyStore -subjectDN CN=mycn,o=ibm,c=us -alias cert1
CWPKI0403I: Trace is being logged to the following location:
           C:\opt\WebSphere\AppClient\logs\caClient.log
CWPKI0422I: Generating a PKCS10 certificate request CWPKI0421I: A PKCS10 certificate was successfully created.  The request     is stored in file:
    C:\opt\WebSphere\AppClient\etc\certReq26924.req  
C:\opt\WebSphere\AppClient\bin>createCertRequest.bat -keyStoreAlias ClientDefaultKeyStore 
-subjectDN CN=mycn,o=ibm,c=us -alias cert1
CWPKI0403I: Trace is being logged to the following location:
           C:\opt\WebSphere\AppClient\logs\caClient.log
CWPKI0422I: Generating a PKCS10 certificate request CWPKI0421I: A PKCS10 certificate was successfully created.  The request     is stored in file:
